How to File a Small Claims Case in Washington State

Someone owes you money and won't pay. In Washington State, small claims court is the simplest way to get a court order forcing them to pay — no lawyer or complex procedures; the clerk assigns a hearing date after filing.

Here's the process from start to finish.

Step 1: Verify Your Claim Fits

Small claims court only handles money disputes. The limit is $10,000 for individuals, $5,000 for business entities under RCW 12.40.010. You can't use small claims to get property returned, force someone to perform a contract, or get an injunction.

Check the statute of limitations before you file. Written contracts have a 6-year window under RCW 4.16.040. Oral contracts, property damage, and security deposit disputes have 3 years under RCW 4.16.080. Miss the deadline and your case is barred permanently.

Step 2: Identify the Defendant

Get the defendant's full legal name right. For a business, search the Washington Secretary of State's CCFS database for the exact entity name and registered agent. For a sole proprietor using a DBA, find the individual owner through the Department of Revenue — you'll name them personally (e.g., "John Smith, individually and d/b/a Smith Auto Repair").

A misspelled corporate name or wrong entity type can make your judgment unenforceable.

Step 3: Send a Demand Letter

Washington law doesn't require a demand letter before filing, but sending one strengthens your case. It proves the defendant had a chance to pay before you took them to court.

Include the exact amount owed, a clear description of the dispute, and a deadline to respond — typically 10 to 14 days. Keep the tone factual, not threatening.

Step 4: File Form MISC 05.0100

This is the Notice of Small Claim — Washington's uniform filing form, revised January 2025. Fill in both parties' information, a brief statement of your claim, and sign the verification under penalty of perjury.

File at your county's District Court clerk counter, by mail, or online if your county offers e-filing (King County has the eCourt portal; Pierce County online filers must contact the court by live chat or phone within 72 hours).

The filing fee is $35 to $50 depending on county. The clerk stamps your form, assigns a case number and hearing date, and gives you copies for service.

Step 5: Serve the Defendant

You must get the defendant served at least 10 calendar days before the hearing. Four valid methods:

• County sheriff — most reliable, costs $30–$65 or more
• Private process server — any competent, disinterested adult 18+ who isn't a party
• Substitute service — delivered to someone of suitable age at the defendant's residence
• Certified mail — with return receipt; the green card must be signed by the defendant personally

You cannot serve the papers yourself. And a USPS tracking confirmation doesn't count — you need the actual signed return receipt.

After service, file Form MISC 05.0200 (Certificate of Service) with the court.

Step 6: Prepare for the Hearing

Organize three identical evidence packets — one for the judge, one for the defendant, one for yourself. Include contracts, invoices, bank statements, photographs, text message printouts (showing dates and phone numbers), and repair estimates.

In some counties (King, Spokane), you'll go through mandatory mediation before seeing a judge. If mediation resolves the dispute, a written agreement is filed and you're done.

Step 7: Attend the Hearing

Both parties testify under oath. Present your evidence clearly and stick to the facts — the judge may ask questions directly. No attorneys unless the judge permits it.

Most hearings last 30 minutes or less. The judge may rule immediately or mail a written decision.

After the Judgment

If you win, the judgment accrues interest at 12% per annum or four percentage points above the 26-week Treasury bill rate, whichever is higher, and is enforceable for 10 years. If the defendant won't pay voluntarily, you can pursue wage or bank garnishment under RCW Chapters 6.17 and 6.27.
