Wash. Rev. Code § 11.76.050
Upon the date fixed for the hearing of such final report and petition for distribution, or either thereof, or any day to which such hearing may have been adjourned by the court, if the court be satisfied that the notice of the time and place of hearing has been given as provided herein, it may proceed to the hearing aforesaid. Any person interested may file objections to the said report and petition for distribution, or may appear at the time and place fixed for the hearing thereof and present his or her objections thereto. The court may take such testimony as to it appears proper or necessary to determine whether the estate is ready to be settled, and whether the transactions of the personal representative should be approved, and to determine who are the legatees or heirs or persons entitled to have the property distributed to them, and the court shall, if it approves such report, and finds the estate ready to be closed, cause to be entered a decree approving such report, find and adjudge the persons entitled to the remainder of the estate, and that all debts have been paid, and by such decree shall distribute the real and personal property to those entitled to the same. Upon the production of receipts from the beneficiaries or distributees for their portions of the estate, the court shall, if satisfied with the correctness thereof, adjudge the estate closed and discharge the personal representative.
The court may, upon such final hearing, partition among the persons entitled thereto, the estate held in common and undivided, and designate and distribute their respective shares; or assign the whole or any part of said estate to one or more of the persons entitled to share therein. The person or persons to whom said estate is assigned shall pay or secure to the other parties interested in said estate their just proportion of the value thereof as determined by the court from the appraisement, or from any other evidence which the court may require.
If it shall appear to the court at or prior to any final hearing that the estate cannot be fairly divided, then the whole or any part of said estate may be sold or mortgaged in the manner provided by law for the sale or mortgaging of property by personal representatives and the proceeds thereof distributed to the persons entitled thereto as provided in the final decree.
The court shall have the authority to make partition, distribution and settlement of all estates in any manner which to the court seems right and proper, to the end that such estates may be administered and distributed to the persons entitled thereto. No estate shall be partitioned, nor sale thereof made where partition is impracticable except upon a hearing before the court and the court shall fix the values of the several pieces or parcels to be partitioned at the time of making such order of partition or sale; and may order the property sold and the proceeds distributed, or may order partition and distribute the several pieces or parcels, subject to such charges or burdens as shall be proper and equitable.
The provisions of this section shall be concurrent with and not in derogation of other statutes as to partition of property or sale.
