A Washington Petition for Divorce (Dissolution) is a legal document that is filed with the court in order to start the process of legally ending a marriage in the state of Washington. The petition must be filed in the county where either spouse resides and must include detailed information about the marriage, such as the date and place of the marriage, the parties’ names, and the reasons for the dissolution. The petition must also include the couple’s agreements about the division of property, debt, and the custody and support of any children. There are two types of Washington Petition for Divorce (Dissolution): contested and uncontested. In an uncontested divorce, both spouses agree to the terms of the divorce, including the division of property and debts, child custody, and child support. In a contested divorce, one or both spouses disagree with the terms of the divorce, and the court must decide the outcome.
