Petition for Dissolution of Marriage in Washington

In Washington, a divorce case begins when one spouse (the “Petitioner”) files a Petition for Dissolution of Marriage with the appropriate Superior Court. This filing signals the start of legal proceedings to end the marriage.

Where to File

  1. County of Filing
    In Washington, you generally file the Petition in the Superior Court of the county where you or your spouse resides.
  2. Residency Requirements
    At least one spouse must be a resident of (or stationed in) Washington at the time the Petition is filed. Washington does not impose a strict “six-month” residency rule, but physical presence or intent to stay is typically required.

Does Filing Immediately Dissolve the Marriage?

No. Filing a Petition for Dissolution does not itself end the marriage. A judge must sign a Final Decree of Dissolution before your divorce is considered complete. Until then, either spouse may generally request to withdraw or dismiss the Petition (subject to local rules and any court orders in place).

Mandatory Waiting Period

Washington imposes a 90-day waiting period from the later of:

  1. Filing the Petition, or
  2. Serving the Other Spouse

The court cannot finalize your divorce before these 90 days expire, except under highly unusual circumstances (e.g., certain domestic violence situations or procedural specifics dictated by local rules). Typically, after the 90-day period, you can move forward with final orders, provided all required documents and steps are complete.

Moving from Petition to Final Decree

  1. Negotiation & Agreement
    If you and your spouse can agree on property division, support, and (if applicable) a parenting plan, you may finalize the divorce as an uncontested matter.
  2. Court Approval
    Only when the judge signs the Final Decree of Dissolution does the marriage legally end.
