Serving Divorce Papers in Washington
Washington requires your spouse to be formally served with the petition for dissolution of marriage. One exception: your spouse can agree to join the petition or accept service instead. Washington Superior Court Civil Rule 4 sets out who can deliver the petition and how. The superior court will not move your case forward without proof that service was completed properly. Most people filing in Washington use the sheriff or another qualified adult to serve the papers. Others skip formal delivery by having their spouse sign an acceptance of service or a joinder. If a spouse cannot be located, Washington allows service by publication after a diligent search and court approval. This page walks through each method, how to prove service, and the deadline your spouse faces once served.

Who can serve divorce papers in Washington
Washington Superior Court Civil Rule 4 says a petition for dissolution of marriage can be served by the sheriff of the county where your spouse can be found. Any competent person who is at least 18 and not a party to the case can also serve it. You, as the petitioner, cannot serve the papers on your spouse yourself. Proof of delivery must be filed with the superior court.
Joining or accepting service instead of being served
Washington family law practice often uses a joinder, where both spouses file the petition together. That avoids formal service entirely. If you file alone, your spouse can still sign an acceptance of service instead. No sheriff has to make a formal delivery. Either document gets filed with the superior court in place of a sheriff's return.
When your spouse cannot be found: service by publication
Under RCW 4.28.100, Washington allows service by publication when a party cannot be found after due diligence. Before a judge approves this method, you must file an affidavit describing the search you conducted. Notice then runs once a week for six consecutive weeks in a qualifying newspaper. Confirm the current newspaper and publication cost with the superior court clerk. No single statewide figure covers this cost.
Proving service happened
Whoever serves your spouse must return proof of service to the superior court clerk. It states when, where, and how the petition was delivered. If your spouse signed a joinder or an acceptance of service instead, that filed document takes the place of the return. The court needs this proof on file before your case can move toward a hearing or final decree.
Response deadline and cost
Once served within Washington State, your spouse generally has 20 days to file a response with the superior court. Sheriff fees for serving papers are set by county. No single statewide dollar figure applies. Confirm the current cost with the sheriff's office in the county of service. A joinder or acceptance of service avoids that fee entirely.
