The Washington Petition for Probate of Lost Will, Letters of Testamentary, & Nonintervention Powers is a legal document used to allow the probate court to grant an estate’s personal representative the authority to administer the deceased’s estate. This document is used in the case of a lost will or when a person dies without making a will. The petition must be filed in the county where the deceased resided at the time of death. The petition includes various provisions allowing the court to appoint a personal representative, issue letters of testamentary, and grant nonintervention powers. Depending on the county, the petition may also be used to request a warship determination or a determination of descent. The Washington Petition for Probate of Lost Will, Letters of Testamentary, & Nonintervention Powers is divided into two types: an uncontested petition and a contested petition. An uncontested petition is used when all interested parties agree on the proposed personal representative, and sign a Consent to Appointment or Waiver of Notice. A contested petition is used when all interested parties do not agree on the proposed personal representative, and the court must make a decision on whom to appoint. The petitioner must include the following information in the petition: the deceased’s name, date of death, and county of residence; the names and addresses of all interested persons; the estimated value of the estate; and a description of the property to be probated. The petition must also include a proposed personal representative, and either a Consent to Appointment or Waiver of Notice. Once the petition is filed, the court will issue an Order of Probate and Letters of Testamentary, and grant nonintervention powers to the appointed personal representative. The personal representative can then take the necessary steps to administer the estate.
