Tex. R. Civ. P. 592
Either at the commencement of a suit or at any time during its progress the plaintiff may file an application for the issuance of a writ of attachment. Such application shall be supported by affidavits of the plaintiff, his agent, his attorney, or other persons having knowledge of relevant facts. The application shall comply with all statutory requirements and shall state the grounds for issuing the writ and the specific facts relied upon by the plaintiff to warrant the required findings by the court. The writ shall not be quashed because two or more grounds are stated conjunctively or disjunctively. The application and any affidavits shall be made on personal knowledge and shall set forth such facts as would be admissible in evidence; provided that facts may be stated based upon information and belief if the grounds of such belief are specifically stated.
No writ shall issue except upon written order of the court after a hearing, which may be ex parte. The court, in its order granting the application, shall make specific findings of facts to support the statutory grounds found to exist, and shall specify the maximum value of property that may be attached, and the amount of bond required of plaintiff, and, further shall command that the attached property be kept safe and preserved subject to further orders of the court. Such bond shall be in an amount which, in the opinion of the court, will adequately compensate the defendant in the event plaintiff fails to prosecute his suit to effect, and to pay all damages and costs which may be adjudged against him for wrongfully suing out the writ of attachment. The court shall further find in its order the amount of bond required of defendant to replevy, which, unless the defendant chooses to exercise his option as provided in Rule 599, shall be the amount of plaintiff's claim, one year's accrual of interest if allowed by law on the claim, and the estimated costs of court. The order may direct the issuance of several writs at the same time, or in succession, to be sent to different counties.
