GREEN, Justice.

Believing herself to be the non-marital child of John G. Kenedy, Jr., Ann M. Fernandez has initiated multiple proceedings in both district court and statutory probate court to set aside decades-old judgments and reopen the estates of Kenedy, his wife, and his sister, and to declare Fernandez an heir to those estates. The defendants filed motions for summary judgment in the district court arguing numerous grounds, including that because Fernandez's heirship claim was barred by limitations, she could not establish an interest in the estates and could not pursue bills of review. The district court granted summary judgment against Fernandez in a broadly-worded order that did not specify the grounds. The principal issue on appeal is whether the district court had jurisdiction to render summary judgment when similar bill of review proceedings and applications for determination of heirship were pending in the probate court. The court of appeals held that the district court lacked subject matter jurisdiction and was required to abate its proceedings until the probate court first resolved questions of heirship. We disagree. Fernandez's pleadings and her direct attack on a previous judgment vested the district court with subject matter jurisdiction. Moreover, the Texas Probate Code does not authorize a probate court to exercise jurisdiction over heirship claims when an estate has been closed for decades and the decedent did not die intestate. We therefore reverse those parts of the court of appeals' judgment that relate to jurisdiction and abatement. Further, we hold that the discovery rule does not apply to inheritance or heirship claims by non-marital children, or bill of review claims to set aside probate judgments. Because Fernandez's claims were barred by the applicable statute of limitations, we render judgment reinstating the district court's judgment. In light of today's ruling, we conclude that none of Fernandez's claims for heirship or inheritance rights to the Kenedy estate remain viable, so we affirm the portion of the court of appeals' judgment that set aside the district court's anti-suit injunction.

I. Facts and Procedural Background

John G. Kenedy, Jr., died in 1948. In his holographic will, Kenedy left all his "property of every character and d[e]scription both personal and mixed" to his wife, Elena Suess Kenedy. After Kenedy's will was probated in the County Court of Kenedy County, Humble Oil Refining Company, which leased mineral interests that were part of Kenedy's estate, brought a will construction suit in district court to resolve a potential ambiguity regarding whether Kenedy's will disposed of all Kenedy's real property (the Humble Oil suit). On October 12, 1949, the district court found that all of Kenedy's heirs were before it and held that the will did not leave an intestacy but instead passed his interest in any property to his wife. The judgment states that "as a matter of law" Kenedy was survived by no children and that "all persons who would have inherited any part of the Estate of John G. Kenedy, Jr., deceased, if he had died intestate as to all or any part of his estate, are parties to this suit and therefore all necessary and interested parties are included among the defendants herein." Kenedy's estate was distributed, taxed, and closed in 1952.

Sarita Kenedy East, Kenedy's sister, died in 1961. East's 1960 will and codicils, which left the bulk of East's estate to The John G. and Marie Stella Kenedy Memorial Foundation and contained a residual clause leaving any remaining property to the Foundation, were admitted to probate later in 1961. After extensive litigation (the Trevino will contest), the district court dismissed several contests to the 1960 will and codicils. See Trevino v. Turcotte, 564 S.W.2d 682, 690 (Tex. 1978). As a part of that litigation, the district court entered a final judgment in 1975 pursuant to a settlement agreement as to some of the parties contesting East's 1960 will. We later affirmed the district court's dismissal judgment, id., and the district court then transferred the Trevino will contest back to the County Court of Kenedy County for a final accounting of East's estate in 1986. The county court closed East's estate in 1987.

Apart from the contests to East's will, a temporary administrator of her estate had also filed an action to set aside certain inter vivos mineral royalty assignments East had made to the Foundation (the Garcia suit). The district court abated this action in 1964, after the Foundation argued that it would own the property at issue under East's will regardless of the status of the inter vivos transfers, if the Trevino will contest failed. After our opinion in Trevino, in September 1978 the district court dismissed the Garcia suit with prejudice.

Mrs. Kenedy passed away in 1984, leaving a will that bequeathed most of her estate to The John G. Kenedy, Jr. Charitable Trust. That will was probated in 1984, the estate was closed in late 1987, and Mrs. Kenedy's interest in the real property at issue was distributed to the Trust. The La Parra Ranch, which was among Kenedy's real property assets that passed to Mrs. Kenedy, was the primary trust asset.

Fernandez was born in 1925 to Maria Rowland, who was then unmarried and worked for the Kenedy family. For years, Fernandez heard rumors and speculation that Kenedy was her father. Fernandez alleges that on Mother's Day of 2000, shortly before her death, Rowland revealed Kenedy's paternity when she told Fernandez's son, Dr. Ray Fernandez, that he bore a resemblance to his grandfather, Kenedy. Fernandez then began engaging in litigation to assert her putative right to inherit from the estates of Kenedy, his wife, and East.

Fernandez filed multiple lawsuits contesting court orders and probate proceedings relating to those estates, and she seeks to reopen the estates and set aside distributions of real and personal property that were made decades ago in those probate proceedings. Fernandez, who did not receive notice of the suits pertaining the estates of Kenedy, his wife, and East, contends that she should have been a party to those suits, that the judgments in those cases are not binding and should be set aside, and that she is entitled to her intestate share. We discuss the relevant underlying proceedings and filings generally in chronological order.

In October 2001, Fernandez filed her initial suit, a bill of review in the County Court of Kenedy County seeking to set aside the order probating Kenedy's will, to reopen Kenedy's estate, and to be declared Kenedy's heir. In May 2002, she filed another bill of review and application for declaration of heirship in Kenedy's estate in the County Court of Kenedy County. She filed additional bill of review proceedings in the County Court of Kenedy County relating to Mrs. Kenedy's estate and East's estate, also seeking a declaration of heirship for these estates.

Fernandez filed three petitions for bill of review in the district court for Kenedy County and Nueces County, seeking to set aside the Humble Oil, Trevino, and Garcia judgments. The district court judgments in those bill of review cases are the subject of appeals currently before us. In May 2002, Fernandez filed the first of these bills of review in the 105th District Court of Nueces County relating to the Trevino will contest ( Trevino bill of review). This suit also sought an accounting and distribution of property including the mineral interests in the land once held by the Kenedys and East.

On June 28, 2002, Judge Guy Herman was appointed to be the statutory probate judge over the above-referenced County Court of Kenedy County matters. On November 5, 2002, citing section 5B of the Texas Probate Code, Judge Herman transferred to himself and consolidated all of the four cases then pending in county court. In the same orders, Judge Herman also purported to transfer to himself the cases then pending in district court, including the Trevino bill of review.

Then, in May 2003, Fernandez filed in district court the other two bills of review that are now the subject of pending appeals. Fernandez initiated the underlying proceedings in the 105th District Court of Kenedy County with a bill of review to set aside the 1949 judgment from the Humble Oil will contest suit, arguing that she should have been notified of and made a party to the decades-earlier Humble Oil proceeding ( Humble Oil bill of review). She also filed a bill of review in the 105th District Court of Nueces County, seeking to set aside the 1978 East dismissal order, claiming that, as East's heir, she should have been notified of and made a party to the Garcia royalty suit ( Garcia bill of review).

In August 2003, Fernandez moved to abate the three district court bill of review cases, and for Judge Herman to transfer the remaining district court cases to himself. The Foundation and Trust filed pleas to the jurisdiction challenging the probate court's jurisdiction to transfer the bill of review cases from the district court. See In re The John G. Marie Stella Kenedy Mem'l Found., 159 S.W.3d 133, 139 (Tex.App.-Corpus Christi 2004, orig. proceeding). On August 27, 2003, Judge Herman denied the pleas to the jurisdiction, id., and signed a second order purportedly transferring and consolidating the Humble Oil and Garcia bill of review district court causes of action into the cause number assigned to the related cases. At this point, all three district court bill of review cases were purportedly transferred and consolidated by Judge Herman.

On petition for writ of mandamus, the court of appeals held that because there was no estate pending in the probate court, Judge Herman lacked authority under section 5B of the Texas Probate Code to transfer the bill of review proceedings that were originally filed in district court. Id. at 146. The court of appeals directed Judge Herman to vacate his transfer orders relating to the three district court bills of review, id., but the record does not show that this has yet happened.

While that mandamus case was pending in the court of appeals, Fernandez sought to exhume Kenedy's remains pursuant to section 711.004 of the Texas Health and Safety Code. On June 18, 2004, two days after the court of appeals issued its mandamus ruling, Judge Herman concluded that he had jurisdiction to consider the exhumation motion. He then granted the motion to exhume to allow DNA testing to determine if Kenedy is Fernandez's biological father. After proceedings in the court of appeals and a hearing before Judge Herman, an exhumation date was set for July 10, 2004. See In re Frost Nat'l Bank, 2004 WL 1505527, at *1 (Tex.App.-Corpus Christi July 6, 2004, orig. proceeding) (per curiam) (denying petition for writ of mandamus seeking protection from the exhumation order). The Foundation and Trust filed petitions for writ of mandamus in this Court, and we stayed the exhumation order.

In January 2006, while the exhumation mandamus cases were pending in this Court, the Trust and Foundation moved for summary judgment in the Trevino and Humble Oil bill of review cases in district court. The Foundation also moved for summary judgment in the Garcia bill of review case in May 2006. The motions presented various grounds for summary judgment, including Fernandez's lack of standing to pursue the bills of review and expiration of the applicable limitations period, both for an heirship determination and for the bill of review itself. Among other things, the Trust and Foundation argued that these bars precluded Fernandez from establishing a right to inherit from Kenedy or East, such that Fernandez could not establish a meritorious claim warranting a bill of review.

Meanwhile, the Foundation also filed an emergency application for temporary restraining order and a request for a permanent injunction in the Trevino and Garcia bills of review cases, and the Trust made similar filings in the Humble Oil bill of review case. The Trust and Foundation argued that Fernandez's filings in probate court were a continuing attempt to circumvent the district court's jurisdiction. The district court issued a temporary restraining order prohibiting Fernandez from proceeding with a motion she had filed in probate court, which sought to reopen Kenedy's estate and to have the bill of review proceedings transferred to the probate court and abated in the district court. Fernandez did not seek appellate court relief from that order.

The action in the district court proceeded. In March 2006, in the Humble Oil and Trevino bills of review, the district court denied Fernandez's motion to abate and denied a motion to transfer. Finally, on March 27, 2006, the district court rendered summary judgment for the Trust and Foundation without specifying the grounds in the Trevino and Humble Oil bill of review cases.

On April 12, 2006, the district court issued permanent anti-suit injunctions in those two cases, enjoining Fernandez from taking actions inconsistent with the district court's judgment in the probate court or any other court, including any attempt to reopen the estates, establish a right to inherit from the estates, set aside the wills, or recover an interest in property distributed from the estates. The district court issued an order on April 25, 2006 that incorporated both the March 27 summary judgment and the April 12 injunctive relief. Fernandez appealed both the summary judgment and the anti-suit injunction in those two cases.

The district court also rendered summary judgment for the Foundation in the Garcia bill of review case on June 22, 2006. The same day, as it had in the other two cases, the district court issued a permanent anti-suit injunction in this case. Fernandez appealed only the anti-suit injunction in the Garcia bill of review case.

Turning to the Humble Oil bill of review, the instant case before us, the court of appeals reversed, concluding that the probate court had dominant jurisdiction over the question of Fernandez's heirship and whether she had an interest in Kenedy's estate. 267 S.W.3d 75, 81-82 (Tex.App.-Corpus Christi 2008, pet. granted). Holding that abatement was required, the court remanded the case to the district court with instructions to abate the petition until the probate court resolves Fernandez's heirship application. Id. at 85. The court of appeals also reversed the anti-suit injunction and rendered judgment against the Trust on its request for injunctive relief. Id. The Trust appealed, and we granted the petition for review. 53 Tex. Sup.Ct. J. 15 (Oct. 23, 2009).

On the Trevino bill of review, the court of appeals also reversed, again concluding that the probate court had dominant jurisdiction and remanding to the district court for abatement. Fernandez v. The John G. Marie Stella Kenedy Mem'l Found., 315 S.W.3d 542, 544 (Tex.App.-Corpus Christi 2008, pet. granted) (mem. op.). As in Humble Oil, the court of appeals reversed the anti-suit injunction and rendered judgment against the Foundation on its request for injunctive relief. Id. at 545. The Foundation appealed, and we granted that petition for review. 53 Tex. Sup.Ct. J. 15 (Oct. 23, 2009).

On the Garcia bill of review, the court of appeals again reversed, this time concluding only that the district court acted improperly by entering an anti-suit injunction. Fernandez v. The John G. Marie Stella Kenedy Found., 315 S.W.3d 542, 544 (Tex.App.-Corpus Christi 2008, pet. granted) (mem. op.). Because Fernandez did not appeal the summary judgment in this case, the court of appeals did not remand the case. Instead, the court of appeals reversed the anti-suit injunction and rendered judgment against the Foundation on its request for injunctive relief. Id. at 545. The Foundation appealed, and we granted that petition for review. 53 Tex. Sup.Ct. J. 15 (Oct. 23, 2009).

II. Summary Judgment

The Trust first argues that the district court had subject matter jurisdiction to render judgment that Fernandez take nothing in her bill of review suit, and that the court of appeals erroneously held that the district court must abate its bill of review proceedings to allow the probate court to determine heirship. "Whether a court has subject matter jurisdiction is a question of law." Tex. Dep't of Parks Wildlife v. Miranda, 133 S.W.3d 217, 226 (Tex. 2004) (citing Tex. Natural Res. Conservation Comm'n v. IT-Davy, 74 S.W.3d 849, 855 (Tex. 2002)). "Whether a pleader has alleged facts that affirmatively demonstrate a trial court's subject matter jurisdiction is a question of law reviewed de novo." Id.

A. Jurisdiction 1. Fernandez's Pleadings

The Trust contends that Fernandez's pleading of facts supportive of standing vested the district court with subject matter jurisdiction over the Humble Oil bill of review case. We agree. Inherent in a court's jurisdiction is the authority to determine whether it can exercise subject matter jurisdiction over the case, including determining standing. See Houston Mun. Employees Pension Sys. v. Ferrell, 248 S.W.3d 151, 158 (Tex. 2007); Camacho v. Samaniego, 831 S.W.2d 804, 809 (Tex. 1992). Standing, which focuses on who may bring an action, is a prerequisite to subject matter jurisdiction. M.D. Anderson Cancer Ctr. v. Novak, 52 S.W.3d 704, 708 (Tex. 2001). To have standing to pursue a bill of review, a person generally must have been a party to the prior judgment or have had a then-existing interest or right that was prejudiced by the prior judgment. See, e.g., Rodriguez ex rel. Rodriguez v. EMC Mortg. Corp., 94 S.W.3d 795, 798 (Tex.App.-San Antonio 2002, no pet.); Lerma v. Bustillos, 720 S.W.2d 204, 205-06 (Tex.App.-San Antonio 1986, no writ). Fernandez contends that, because of her biological relationship to Kenedy, she has an interest in the Kenedy estate that was prejudiced by the 1949 Humble Oil judgment.

It has long been the rule that a plaintiff's good faith allegations are used to determine the trial court's jurisdiction. See, e.g., Brannon v. Pac. Employers Ins. Co., 148 Tex. 289, 224 S.W.2d 466, 469 (1949). A court may presume the truth of allegations supportive of standing to determine standing and dispose of litigation through summary judgment. See Tex. Ass'n of Bus. v. Tex. Air Control Bd., 852 S.W.2d 440, 446 (Tex. 1993) ("[W]hen a Texas appellate court reviews the standing of a party sua sponte, it must construe the petition in favor of the party. . . ."); Brown v. Todd, 53 S.W.3d 297, 305 n. 3 (Tex. 2001) ("Because standing is a component of subject matter jurisdiction, we consider [it] as we would a plea to the jurisdiction, construing the pleadings in favor of the plaintiff."); see also Laidlaw Waste Sys. (Dallas), Inc. v. City of Wilmer, 904 S.W.2d 656, 660 (Tex. 1995) (assuming that petitioner had standing to affirm summary judgment against petitioner); O'Quinn v. State Bar of Tex., 763 S.W.2d 397, 403 (Tex. 1988) (assuming that party had standing to decide that challenge lacked merit). In this case, Fernandez pled in her bill of review petition in district court that she is Kenedy's non-marital child and, because of that relationship, she is entitled to an intestate inheritance if the district court's 1949 judgment negating intestacy is set aside. For purposes of determining standing, then, the district court could presume that Fernandez is, as she alleges, Kenedy's biological child. The Trust favors such an assumption, and Fernandez, who is hardly in a position to challenge it, made no objection on this basis. We reject Fernandez's peculiar argument that the district court should not have assumed her pleaded basis for standing to be true.

The court of appeals believed that employing such a presumption amounts to conferring standing by estoppel. 267 S.W.2d at 81 (citing Tex. Ass'n of Bus., 852 S.W.2d at 443-46). In this case, the Trust did ask the district court to assume paternity for purposes of its summary judgment motion. But, as we have already discussed, Fernandez did not object to that request, and Fernandez's allegations, taken as true, were sufficient to establish standing. We have never said that presuming heirship in these sorts of cases amounts to conferring standing by estoppel or by agreement, or that this situation should depart from the general rule that the plaintiff's good faith allegations are used to determine jurisdiction. We see no reason to alter it now, as such a rule would prevent parties from ever stipulating to facts relating to parentage and would prevent courts from deciding dispositive motions not dependent on parentage (e.g., laches and limitations), without some sort of evidentiary inquiry into heirship claims. See Bland Indep. Sch. Dist. v. Blue, 34 S.W.3d 547, 554 (Tex. 2000) (recognizing that plaintiffs do not have to "put on their case simply to establish jurisdiction"). In this case, we conclude that Fernandez's pleadings conferred standing, regardless of whether the alleged relationship was true or subject to rebuttal on the merits.

2. Direct Attack on 1949 Judgment

Because Fernandez's claims are a direct attack on the 1949 Humble Oil judgment, brought by bill of review, the district court had authority to determine Fernandez's standing to proceed, including whether she can establish heirship. A bill of review is brought as a direct attack on a judgment that is no longer appealable or subject to a motion for new trial. King Ranch, Inc. v. Chapman, 118 S.W.3d 742, 751 (Tex. 2003). Because it is a direct attack, a bill of review must be brought in the court that rendered the original judgment, and only that court has jurisdiction over the bill. See, e.g., In re The John G. Marie Stella Kenedy Mem'l Found., et al., 159 S.W.3d 133, 141, 146 (Tex.App.-Corpus Christi 2004, orig. proceeding) (holding that Judge Herman "not only erroneously concluded he had jurisdiction over these matters, but also actively interfered with the jurisdiction of the district courts"); Richards v. Comm'n for Lawyer Discipline, 81 S.W.3d 506, 508 (Tex.App.-Houston [1st Dist.] 2002, no pet.) ("Because a bill of review is a direct attack on a judgment, only the court rendering the original judgment has jurisdiction over the proceeding."); Solomon, Lambert, Roth Assocs. Inc. v. Kidd, 904 S.W.2d 896, 900 (Tex.App.-Houston [1st Dist.] 1995, no writ) ("The requirement that a bill of review be filed in the same court that rendered the judgment under attack is a matter of jurisdiction. . . ."); Martin v. Stein, 649 S.W.2d 342, 346 (Tex.App.-Fort Worth 1983, writ ref'd n.r.e.) (per curiam) ("A bill of review or a petition in the nature of a bill of review is a proceeding in equity that has for its purpose the reversal or modification of a prior judgment of the same trial court. It is not a means of appeal of a judgment of one trial court to another trial court."); cf. Austin Indep. Sch. Dist. v. Sierra Club, 495 S.W.2d 878, 881 (Tex. 1973) ("A direct attack is a proceeding instituted for the purpose of correcting the earlier judgment. It may be brought in the court rendering the judgment or in another court that is authorized to review the judgment on appeal or by writ of error. The purpose of a direct attack is to change the former judgment and secure the entry of a correct judgment in lieu of the earlier incorrect one."). Here, the district court that rendered the 1949 will construction judgment has exclusive jurisdiction over any attack on that judgment by bill of review. See In re Kenedy Mem'l Found., 159 S.W.3d at 143-44, 146 (holding that, because the bill of review cases in the underlying proceedings were properly filed in the courts that rendered the judgments under attack, jurisdiction attached in the district court). It follows that, under the facts of this case, all issues bearing on the validity of Fernandez's attack on that earlier judgment are necessarily resolvable by the district court as part of its determination of the bill of review. When the district court has exclusive jurisdiction over the subject matter of a claim, Fernandez cannot procure relief in the probate court by characterizing the issue as solely one of heirship. See, e.g., Taylor v. Hill, 249 S.W.3d 618, 625 (Tex.App.-Austin 2008, pet. denied) (holding that district court had jurisdiction over partition action and rejecting argument that claim requiring determination of heirs' interest must be heard only in probate court); Trevino v. Lerma, 486 S.W.2d 199, 200 (Tex.Civ.App.-Beaumont 1972, no writ) (holding that district court had exclusive jurisdiction to hear suit to set aside deed and that claimants "could procure no relief in the probate court under the provisions of § 48 of the Probate Code").

3. Probate Code

The court of appeals believed that "[t]he real jurisdictional problem plaguing the summary judgment is that it was rendered by a district court that did not have control over the heirship issues that are central to Fernandez's petition." 267 S.W.3d at 81. The court held that whether Fernandez had an interest in Kenedy's and East's estates "is undoubtedly a probate question that must be resolved by the probate court and, in this case, cannot be resolved in the district court." Id. at 82. But the only given authority for this conclusion was a footnote in Palmer v. The Coble Wall Trust Co., Inc., 851 S.W.2d 178, 180 n. 3 (Tex. 1992), which does not mention exclusive jurisdiction and does not hold that only a county court acting in probate has jurisdiction over heirship claims in the circumstances presented here. The cited footnote primarily addresses counties in which there is a statutory county court or a statutory probate court, id., which is not the case in Kenedy County. However, the footnote does go on to explain:

To further complicate matters, the district courts exercise some probate jurisdiction. The Probate Code provides that "[t]he district court shall have original control and jurisdiction over executors, administrators, guardians and wards under such regulations as may be prescribed by law." TEX. PROB. CODE § 5(a) (Supp. 1992). In those counties where there is no statutory court exercising probate jurisdiction, most probate matters must be filed in the constitutional county court, id. § 5(b); however, the county judge may transfer contested matters to the district court, which may then hear them "as if originally filed in district court." Id. In this situation the county court retains jurisdiction over the uncontested portions of the case. Id. The county judge may also request the assignment of a statutory probate judge to hear contested matters. Id.

Palmer, 851 S.W.2d at 180 n. 3. Neither section 5(b) of the Probate Code nor the footnote in Palmer addresses the situation at hand, which involves attacks on district court judgments in cases where the estates were fully administered and closed decades ago. In fact, the Probate Code does not authorize probate courts to exercise jurisdiction in these circumstances, where a decedent died testate and his or her estate was fully administered and closed.

In counties such as Kenedy with no statutory probate court, county court at law, or other statutory court exercising probate jurisdiction, "all applications, petitions, and motions regarding probate and administrations shall be filed and heard in the county court," except that in contested probate matters, the contested portion can be assigned to a statutory probate court judge or transferred to district court. TEX. PROB. CODE § 5(b). "All courts exercising original probate jurisdiction shall have the power to hear all matters incident to an estate." Id. § 5(f). "'[I]ncident to an estate' . . . include[s] the probate of wills, the issuance of letters testamentary and of administration, and the determination of heirship, and also include[s], but [is] not limited to, all claims by or against an estate, . . . all actions to construe wills, . . . and generally all matters relating to the settlement, partition, and distribution of estates of deceased persons." Id. § 5A(a). But we have said that a "court empowered with probate jurisdiction may only exercise its probate jurisdiction over matters incident to an estate when a probate proceeding related to such matters is already pending in that court." Bailey v. Cherokee County Appraisal Dist., 862 S.W.2d 581, 585 (Tex. 1993); see TEX. PROB. CODE § 5A(a), (b). Therefore, the probate court in this case could exercise jurisdiction over Fernandez's heirship claim only if, before Fernandez brought that claim, a probate proceeding was already pending in that court. In this case, there is no open or pending estate in the probate court to which an heirship proceeding would be incident and, thus, the Probate Code does not authorize the probate court's exercise of jurisdiction to determine heirship. See Schwartz v. Jefferson, 520 S.W.2d 881, 889 (Tex. 1975) ("The mere filing of a bill of review does not affect the finality of the judgment which is sought to be set aside."); In re Kenedy Mem'l Found., 159 S.W.3d at 145 (acknowledging that the estates of Kenedy, his wife, and East "were closed long ago and not reopened by the mere filing of the bills of review," so none of the estates were "pending"). Indeed, if the mere filing of a bill of review or an application for declaration of heirship were to reopen a closed estate and render it "pending" within the meaning of the Probate Code, no estate or probate judgment would ever truly be final because such judgments would always be subject to additional litigation in courts other than those that issued the judgments.

Moreover, section 48 of the Probate Code provides that a proceeding to declare heirship may be filed in the probate court only when a person died intestate as to some or all of his or her property, when a will has been probated or estate administered but real or personal property was omitted, or when there has not been a final disposition. TEX. PROB. CODE § 48(a) (permitting suit for declaration of heirship "[w]hen a person dies intestate" and "there shall have been no administration in this State upon his estate" or when a will has been probated or an estate administered but property was "omitted from such will or from such administration"); see id. § 3(o) (defining "heirs" as "those persons . . . who are entitled under the statutes of descent and distribution to the estate of a decedent who dies intestate"). That is not the case here. Because Kenedy left a will that disposed of all his property, as determined by the district court in the Humble Oil suit, and because his estate was fully administered and closed, the Probate Code does not authorize the probate court to determine heirship. See Cogley v. Welch, 34 S.W.2d 849, 853 (Tex.Comm'n App. 1931, judgm't adopted) (holding that court has "absolutely no authority . . . to exercise jurisdiction to declare heirship" when decedent died testate); McMahan v. Naylor, 855 S.W.2d 193, 194-95 (Tex.App.-Corpus Christi 1993, writ denied) (recognizing that issue of intestacy should be determined before heirship); Guajardo v. Chavana, 762 S.W.2d 683, 684-85 (Tex.App.-San Antonio 1988, writ denied) (holding that heirship is not justiciable before intestacy is established); Buckner Orphans Home v. Berry, 332 S.W.2d 771, 775-76 (Tex.Civ.App.-Dallas 1960, writ ref'd n.r.e.) (holding that putative heirs "would first have to annul the wills left by deceased" before they had "such interest as would entitle them to come into the probate court asking for a declaration of heirship, or claiming rights in the estate as heirs"). Authority to decide Fernandez's heirship claims rests solely with the district court as part of its exclusive jurisdiction over the bills of review.

B. Abatement

The Trust challenges the court of appeals' holding that the later-filed case — the Humble Oil bill of review in the district court — must be abated to allow resolution of the earlier filed applications for declaration of heirship in the probate court. 267 S.W.3d at 83. As a general rule, "the court in which suit is first filed acquires dominant jurisdiction to the exclusion of coordinate courts." Bailey v. Cherokee County Appraisal Dist., 862 S.W.2d 581, 586 (Tex. 1993). We need not decide whether the general rule of dominant jurisdiction applies in this case, or in cases involving later-filed direct attacks that are exclusively within the jurisdiction of another court, because here Fernandez's claims are not within the jurisdiction of the probate court. See Gonzalez v. Reliant Energy, Inc., 159 S.W.3d 615, 622 (Tex. 2005) (holding that a dominant-servient inquiry was not implicated where the pleadings in the second-filed case could not be equally maintained in the first); Schuele v. Schuele, 119 S.W.3d 822, 824 (Tex.App.-San Antonio 2003, no pet.) (holding that the concept of dominant jurisdiction may apply only "when separate suits are filed in courts with concurrent jurisdiction"). Accordingly, we reverse the portion of the court of appeals' judgment remanding the case to the district court for abatement.

C. Merits

Although the court of appeals did not review the merits of the summary judgment, the Trust asks us to affirm that judgment, noting that the judgment does not involve and could not be affected by resolution of Fernandez's heirship claim. To avoid unnecessary delay, we may consider issues of law rather than remanding them to the court of appeals. Placencio v. Allied Indus. Int'l, Inc., 724 S.W.2d 20, 22 (Tex. 1987); see TEX.R.APP. P. 60.2(c) ("The Supreme Court may . . . reverse the lower court's judgment in whole or in part and render the judgment that the lower court should have rendered."). We therefore next consider whether Fernandez's claims are barred by limitations, one of the grounds on which the Trust sought summary judgment and Fernandez addressed on appeal. See Malooly Bros., Inc. v. Napier, 461 S.W.2d 119, 121 (Tex. 1970) (recognizing that we can affirm a trial court's judgment on a single valid ground). We review a trial court's grant of summary judgment de novo. Tex. Mun. Power Agency v. Pub. Util. Comm'n, 253 S.W.3d 184, 192 (Tex. 2007). A defendant who conclusively negates at least one of the essential elements of a cause of action or conclusively establishes an affirmative defense is entitled to summary judgment. Randall's Food Markets, Inc. v. Johnson, 891 S.W.2d 640, 644 (Tex. 1995).

1. Limitations

When limitations plainly bars a putative heir from proving her heirship, a court is not required to waste time and resources on a paternity determination before disposing of her claims. See Little v. Smith, 943 S.W.2d 414, 423 (Tex. 1997) (affirming summary judgment barring belated claims for inheritance, without first determining whether putative heir was, in fact, decedent's biological granddaughter). The district court in this case granted summary judgment on both no-evidence and traditional motions for summary judgment in a broadly-worded order that does not specify its reasons. Among other grounds, the motions asserted the affirmative defense of limitations and argued that the discovery rule does not apply because its application would frustrate the state's policy of preserving finality in probate proceedings.

When an heirship claim is brought after an administration of the decedent's estate or a conveyance of the decedent's property to a third party, courts have applied the four-year residual limitations period of Texas Civil Practice and Remedies Code section 16.051. See, e.g., Cantu v. Sapenter, 937 S.W.2d 550, 552 (Tex.App.-San Antonio 1996, writ denied); Smith v. Little, 903 S.W.2d 780, 787-88 (Tex.App.-Dallas 1995), rev'd in part on other grounds, 943 S.W.2d 414 (Tex. 1997). Under any conceivable accrual date, the four-year statute of limitations ran well before Fernandez first asserted claims to the Kenedy and East estates. Fernandez conceded that the residual statute of limitations applies and has never denied that it bars her heirship claim absent the application of the discovery rule to save her claims, arguing that we should apply the discovery rule in heirship cases such as this.

2. Discovery Rule

"Texas courts have refused to apply the discovery rule to claims arising out of probate proceedings in most instances. . . ." Little, 943 S.W.2d at 420. Fernandez does not cite a single case holding that the discovery rule applies to save a non-marital child's heirship claim. Indeed, we have not applied the discovery rule in such a context. See Natural Gas Pipeline Co. of Am. v. Pool, 124 S.W.3d 188, 198 (Tex. 2003) ("This is tantamount to saying that the running of limitations is suspended until the record titleholder obtains actual knowledge of what it owns. This is a novel proposition indeed. It would mean, for example, that limitations would be suspended whenever heirs did not realize that they had inherited an interest. That has never been the law in Texas.") We have, however, held that the rule does not apply to belated claims of inheritance brought by adoptees. Little, 943 S.W.2d at 420. In that case, we recognized the difficulty of promptly bringing inheritance claims:

In many cases, however, adoptees may be unable to timely assert inheritance rights, even with the exercise of the utmost diligence. Not all adoptees may know that they are adopted within the applicable limitations period. Even if they know that they are adopted, they may not know where they were born or, more to the point, where the adoption proceedings occurred, so that they may attempt to obtain access to their birth records. Conducting a meaningful search for your identity is difficult if you do not know where to begin that search. And assuming an adoptee found the correct court to petition, that court could well refuse to open adoption records if the only basis for doing so was to allow the adoptee to see if any inheritance claims existed.

Id. at 418. A non-marital child who grows up not knowing the identity of her father could be said to face similar difficulties. But the Court in Little balanced those concerns against a "strong public interest in according finality to probate proceedings," declining to apply the discovery rule. Id. at 421 (analyzing legislative policy governing adoption). Although the Little context of the legislative scheme governing adoption is distinguishable from the instant case, the Court's reasoning in Little applies with equal force to belated inheritance claims brought by non-marital children. See Turner v. Nesby, 848 S.W.2d 872, 877-78 (Tex.App.-Austin 1993, no writ) (holding that a state's interest in orderly administration of estates and finality of judgments distributing estates can provide a basis for barring a non-marital child's claims against an estate, even if meritorious); see also TEX. PROB. CODE §§ 40, 42(b) (demonstrating that section 42(b), which allows non-marital children to inherit from their biological parents, is in all relevant respects the same as section 40, which allows adopted children to inherit from their biological parents). We have long recognized the importance of according finality to judgments, and we have held courts to stringent bill of review standards to protect that policy favoring finality. See, e.g., Transworld Fin. Servs. Corp. v. Briscoe, 722 S.W.2d 407, 407 (Tex. 1987) ("The grounds upon which a bill of review can be obtained are narrow because the procedure conflicts with the fundamental policy that judgments must become final at some point."); Alexander v. Hagedorn, 148 Tex. 565, 226 S.W.2d 996, 998 (1950) ("As said by the Supreme Court of California, 'Endless litigation, in which nothing was ever finally determined, would be worse than occasional miscarriages of justice.'") (quoting Pico v. Cohn, 91 Cal. 129, 25 P. 970, 971 (1891)); Johnson v. Templeton, 60 Tex. 238, 238 (1883) ("Where the final judgment of a court of competent jurisdiction has been once solemnly pronounced, it ought not to be lightly disturbed. It is alike the interest of individual suitors and of the public at large that there should be at some period an end put to litigation."). Indeed, if we were to apply the discovery rule in this context, we would subject estates to open-ended litigation, a result squarely at odds with the policy that has informed our jurisprudence for more than a century. See Kerlin v. Sauceda, 263 S.W.3d 920, 932 n. 28 (Tex. 2008) (Brister J., concurring) ("Recent years have seen a number of suits in South Texas seeking to reopen title claims to lands that have been dormant for decades or centuries.").

Fernandez argues that application of the discovery rule is constitutionally required and that the United States Supreme Court already weighed the relevant policies and found the policy in favor discovery rule application to allow non-marital children to assert their inheritance rights to be the stronger interest. See Reed v. Campbell, 476 U.S. 852, 856, 106 S.Ct. 2234, 90 L.Ed.2d 858 (1986); Trimble v. Gordon, 430 U.S. 762, 776, 97 S.Ct. 1459, 52 L.Ed.2d 31 (1977). We disagree. In Trimble v. Gordon, the United States Supreme Court struck down on equal protection grounds a statute that allowed non-marital children to inherit from their intestate mothers only, while children of a marriage could inherit from both their intestate mothers and their fathers. 430 U.S. at 767, 97 S.Ct. 1459. Under the Court's analysis, a state could not provide for the total statutory disinheritance of a child from a father's estate where the child was born out of wedlock without subsequent marriage of his or her parents. Id. Later, in Reed v. Campbell, the Court struck down a Texas statute barring non-marital children from inheriting from their fathers except under special circumstances, such as where their parents had subsequently married. 476 U.S. at 857, 106 S.Ct. 2234. Although a state cannot completely bar the inheritance of non-marital children, the Court clearly indicated that states may place reasonable limitations on such inheritance, so that estates do not remain subject to claims indefinitely:

The state interest in the orderly disposition of decedents' estates . . . justifies the enforcement of generally applicable limitations on the time and the manner in which claims may be asserted. After an estate has been finally distributed, the interest in finality may provide an additional, valid justification for barring the belated assertion of claims, even though they may be meritorious and even though mistakes of law or fact may have occurred during the probate process.

Id. at 855-56, 106 S.Ct. 2234; see Lalli v. Lalli, 439 U.S. 259, 268, 99 S.Ct. 518, 58 L.Ed.2d 503 (1978) (stating that the Court has long recognized that a state's goal to provide for the just and orderly disposition of property at death "is an area with which the States have an interest of considerable magnitude"). Neither the United States Supreme Court nor this Court has held that the discovery rule applies to claims made by non-marital children, and we see no reason to change course today.

Because the discovery rule does not apply in this case, and because Fernandez concedes that absent application of the discovery rule her claims are time-barred, we need not consider when Fernandez discovered or by the exercise of reasonable diligence should have discovered the truth of her paternity. Instead, because the four-year residual limitations period expired long before Fernandez filed her bills of review, we reinstate the district court's summary judgment. See Ladehoff v. Ladehoff, 436 S.W.2d 334, 336 (Tex. 1968) (holding that a judgment admitting a will to probate is "binding upon the whole world and specifically upon persons who have rights or interest in the subject matter, and this is so whether those persons were or were not personally served").

III. Anti-suit Injunction

The court of appeals held that because its summary judgment was improper and its proceedings should have been abated, the district court could not enter an anti-suit injunction. 267 S.W.3d at 84-85. A court may exercise its discretion to issue an anti-suit injunction in four circumstances: "1) to address a threat to the court's jurisdiction; 2) to prevent the evasion of important public policy; 3) to prevent a multiplicity of suits; or 4) to protect a party from vexatious or harassing litigation." Gonzalez v. Reliant Energy, Inc., 159 S.W.3d 615, 623 (Tex. 2005). "The party seeking the injunction must show that 'a clear equity demands' the injunction." Golden Rule Ins. Co. v. Harper, 925 S.W.2d 649, 651 (Tex. 1996) (per curiam) (quoting Christensen v. Integrity Ins. Co., 719 S.W.2d 161, 163 (Tex. 1986)). Because we hold that the probate court lacks jurisdiction over Fernandez's heirship claims, we do not foresee a continuing threat of Fernandez resuming this litigation in other courts. Accordingly, while we disagree with the court of appeals' reasoning, we affirm the portion of the judgment that the district court's anti-suit injunction be reversed and the Trust's request for injunctive relief be denied. See Univ. of Tex. v. Morris, 162 Tex. 60, 344 S.W.2d 426, 429 (1961) (recognizing that this Court is not constrained to the trial court record at the time an injunction was issued when events subsequent to the issuance of an anti-suit injunction "render the cause for injunctive relief entirely moot or academic"); see also Gannon v. Payne, 706 S.W.2d 304, 307 (Tex. 1986) ("The circumstances of each situation must be carefully examined to determine whether the [anti-suit] injunction is required to prevent an irreparable miscarriage of justice.").

IV. Conclusion

For the reasons expressed above, we reverse the portions of the court of appeals' judgment that relate to jurisdiction and abatement. We hold that the discovery rule does not apply to heirship and inheritance claims brought by non-marital children, or to bill of review claims to set aside probate judgments. We therefore render judgment reinstating the district court's summary judgment. We affirm the portion of the court of appeals' judgment that relates to the anti-suit injunction.
