How to Serve Divorce Papers in Oregon

If you filed a sole petition for dissolution in Oregon, you must formally serve your spouse with the filed petition, summons, and automatic restraining order before the case can proceed. Co-petitioners skip this entirely — but everyone else needs to get service right. Botch it and the judge won't sign your final judgment.

Who Can Serve Papers

Under ORCP 7, the person who serves the papers must be:

• At least 18 years old
• Not a party to the case (you cannot serve your own spouse)
• A resident of the state where service takes place

This means a county sheriff, private process server, or any qualifying friend or family member can serve. The petitioner's attorney can arrange service but cannot personally hand the papers to the respondent.

Five Methods of Service

Personal service: Someone physically hands the petition, summons, and restraining order directly to the respondent. This is the most straightforward method and is complete the moment the papers are delivered.

Substituted service: If the respondent isn't home, the server can leave copies with a person at the respondent's dwelling who is at least 14 years old, then mail copies to the same address by first-class mail. Both steps must happen — leaving papers without mailing is insufficient.

Office service: The server leaves copies with the person apparently in charge at the respondent's workplace during normal business hours, then mails copies by first-class mail. Like substituted service, both the delivery and mailing are required.

Service by mail: This requires two separate mailings — one by first-class mail and one by certified or registered mail with a return receipt. Service is only complete when the respondent signs the return receipt. If they refuse to sign, service by mail fails and you need another method.

Acceptance of Service: The respondent voluntarily signs a form acknowledging they received the papers. This is free and instant, but it's entirely optional — the respondent can refuse. Importantly, signing an Acceptance of Service does not mean they agree with what the petition asks for. It only waives formal service.

Alternative Service (When You Can't Find Your Spouse)

If the respondent has vanished and you've conducted a diligent search, you can file an Ex Parte Motion for Alternative Service under ORCP 7D(6). The court may authorize service by:

• Posting at the courthouse
• Publication in a newspaper of general circulation
• Email or text message
• Social media posting

You must file a declaration explaining exactly what steps you took to locate the respondent before the court will grant alternative service. "I called and they didn't answer" isn't enough — courts expect documented efforts including checking with mutual contacts, searching public records, and attempting service at last known addresses.

Filing Proof of Service

After service is completed, the person who served the papers must complete and sign a Proof of Service form documenting when, where, and how service occurred. This form gets filed with the court clerk.

Without a properly filed Proof of Service (or a signed Acceptance of Service), the judge cannot enter a default judgment and may refuse to sign even a stipulated judgment.

The 30-Day Response Clock

Service starts the respondent's 30-day window to file a formal Response with the court. If they respond, the case becomes contested (or proceeds toward a stipulated judgment if they agree to terms). If 30 days pass with no response, the petitioner can file a Motion for Order of Default.

Common Service Mistakes

Serving papers yourself. Petitioners cannot serve their own spouse — any service performed by a party to the case is legally void.

Not mailing after substituted service. Leaving papers with a household member but skipping the required first-class mailing means service was never completed. The 30-day clock never starts.

Delaying service. There's no strict statutory deadline for service in Oregon, but excessive delay can result in the case being dismissed for failure to prosecute. Courts generally expect service within 60-63 days.
