The 10-Day Rule: Serving a Washington Small Claims Defendant

This is one of the procedures covered in How Washington Small Claims Courts Work. After a claim is filed, the court sets a hearing date and the plaintiff is responsible for getting the notice of small claim into the defendant’s hands within the statutory window. This article explains the two service methods Washington allows, who may serve the notice, how service works for an individual versus a business, the calendar-day deadline, and the proof of service the court expects before the hearing.

The two methods of service Washington allows

RCW 12.40.040 specifies exactly two ways the notice of small claim may be served. The first is service “as provided for the service of summons or complaint and notice in civil actions as described in RCW 4.28.080,” which covers personal delivery and the substituted-service alternative used in regular civil cases. The second is “registered or certified mail if a return receipt with the signature of the party being served is filed with the court.”

Email, ordinary first-class mail without a return receipt, fax, and informal hand-off without compliance with the personal-service rules are not authorized. Service that does not follow one of the two statutory methods does not give the district court power to enter judgment against the defendant, and a judgment entered without valid service can be vacated under CRLJ 60.

The statute also restricts what can be served with the notice. No other legal document or process may be attached. Court-provided information about the small claims department, local procedure, and dispute resolution services may be included.

Who can serve the notice

The plaintiff cannot serve the defendant. Under CRLJ 4(c), the rule that applies to process in courts of limited jurisdiction, the notice “may be served by any person who is competent to be a witness in the action, other than a party.” In practice that means any adult who is not a plaintiff in the case can serve it. Three common choices:

• A county sheriff’s office or marshal. Fees are set by RCW 36.18.040 and can be added to the judgment if the plaintiff wins.
• A registered process server. Washington does not require statewide licensing, but King, Pierce, Snohomish, and Spokane counties register process servers under local rules. Fees typically run $40 to $75 for routine service.
• A friend or relative who is at least 18 and not a party to the case. The person serving must be willing to sign a declaration describing the service.

For service by certified mail under the second statutory method, the clerk of the district court may mail the notice on the plaintiff’s behalf in many counties, with the return receipt filed directly with the court. The plaintiff pays the mailing fee at filing.

Serving an individual defendant

Personal service on a person who is not a represented business entity is governed by RCW 4.28.080(14). The notice can be delivered to the defendant personally, anywhere the defendant can be found in the state, or it can be left “at the house of his or her usual abode with some person of suitable age and discretion then resident therein.” A teenager who lives at the address generally qualifies; a casual visitor does not.

If personal delivery cannot be accomplished with reasonable diligence, RCW 4.28.080(15) provides a fallback. A copy can be left at the defendant’s usual mailing address with a person of suitable age and discretion who is a resident, proprietor, or agent of that address, and a second copy must then be sent by first-class mail, postage prepaid, to the defendant at the same address. The statute is explicit that “usual mailing address does not include a United States postal service post office box or the person’s place of employment.”

Substituted service under subsection (15) is deemed complete on the tenth day after the required mailing. That ten-day completion period is in addition to the ten-day pre-hearing notice deadline discussed below, so a plaintiff relying on substituted service has to start the process at least 20 days before the hearing.

Serving a business or registered entity

Service on a corporation, limited liability company, limited partnership, or other entity that has filed organizational documents in Washington is governed by RCW 4.28.080(8), which routes to RCW 23.95.450. The notice is delivered to the entity’s registered agent at the address on file with the Washington Secretary of State.

The current registered agent and registered office for a Washington-registered entity, or a foreign entity registered to do business in the state, can be looked up through the Corporations and Charities Filing System operated by the Secretary of State. Service on a stale registered-agent address is not valid; if the agent has resigned or the entity has been administratively dissolved, RCW 23.95.450 specifies the alternate addresses that can be used.

For sole proprietorships and general partnerships that have no registered agent, service is on the owner or any general partner under the individual-service rules in RCW 4.28.080(14).

The certified-mail option through the court

The second method under RCW 12.40.040, registered or certified mail with a signed return receipt, is the simpler route for defendants who can be reliably reached at a known address and who are likely to sign for mail. Most district courts handle the mailing through the clerk’s office at filing.

Service by this method is complete only when the defendant personally signs the return receipt card. A receipt signed by a spouse, a roommate, or someone else at the address does not satisfy the statute, and the court will reject the proof if the signature does not match the named defendant.

The signed return receipt must be filed with the court before the hearing. If the receipt does not come back signed, or comes back signed by the wrong person, the plaintiff has to switch to personal service under the first statutory method.

Proof of service and the 10-day rule

The court does not assume service happened just because the plaintiff says so. Whichever method was used, the plaintiff has to put written proof in the file before the hearing.

1. Identify the deadline from the hearing date

   Count back at least ten calendar days from the hearing the clerk assigned at filing. Service must be complete by that day. If substituted service under RCW 4.28.080(15) is used, count back at least twenty calendar days, because that method does not become complete until the tenth day after mailing.

2. Have the notice served

   Arrange for an adult who is not a party to deliver the notice in person, or for the clerk or a process server to send it by certified mail with return receipt. The server brings a blank declaration of service to fill out as soon as service is complete.

3. Get the server's signed declaration or the return receipt

   For personal or substituted service, the server completes a declaration stating who was served, where, when, and how. For certified-mail service, the signed return receipt card is the proof.

4. File the proof with the court

   File the declaration of service or the return receipt with the same district court where the claim was filed, before the hearing date. Many courts accept the proof at the hearing itself, but filing in advance avoids continuances if the judge wants to review the proof first.

A declaration of service that omits the time, address, or manner of service may be treated as defective even if service actually happened. Standard declaration forms are available from the clerk and from county district court self-help centers.

What if the defendant cannot be served

A defendant who cannot be located, who refuses to accept service, or whose registered agent is no longer valid creates a procedural problem the plaintiff has to solve before the hearing date. Three patterns are common:

A defendant who is evading service can still be served under the substituted-service rule in RCW 4.28.080(15), as long as the plaintiff can document reasonable diligence: repeated attempts at the home address, attempts at different times of day, and confirmation that the person actually lives there.

A defendant who has moved out of state can be served outside Washington under RCW 4.28.180 if Washington has personal jurisdiction over them. The methods are the same; the service just happens in the other state.

A defendant who genuinely cannot be located, after diligent search, requires service by publication under RCW 4.28.100, and even then only in the limited circumstances the statute authorizes. Publication is not generally available in routine small claims cases for money owed.

When the deadline cannot be met, the right step is to ask the court for a continuance before the hearing. A continuance request explaining what service has been attempted and what additional time is needed will usually be granted; failing to appear, or appearing without valid service, can result in dismissal.
