How to File a Small Claims Lawsuit in Washington (2026)
Reviewed by DocDraft Legal Team · Washington · Last updated May 12, 2026
Washington Small Claims Department of District Court handles claims up to $10,000 for natural persons and $5,000 for entities under RCW 12.40.010. Filing fees are $50 in most counties. The statute of limitations is 6 years for written contracts and 3 years for oral contracts.
How does Washington small claims court compare to other states?
Washington is unusual in two ways. First, it caps natural-person plaintiffs at $10,000 and entity plaintiffs at $5,000 under RCW 12.40.010, the only state to use a split limit. Second, RCW 12.40.080 bars attorneys from small claims trials without the judge's express consent. Most states allow attorneys with a uniform claim cap.
What is the maximum amount you can sue for in small claims court in Washington?
Under RCW 12.40.010, natural persons can sue for up to $10,000 and corporations, LLCs, and other entities for up to $5,000 in the Small Claims Department of District Court. Claims above these caps must be filed in the regular District Court civil docket (up to $100,000) or Superior Court.
Can a business sue or be sued in Washington small claims court?
Yes. Corporations, LLCs, partnerships, and other entities can sue or be sued in Washington's Small Claims Department subject to a $5,000 cap under RCW 12.40.010, half the $10,000 cap for natural persons. Entities must appear through a non-attorney employee under RCW 12.40.080. Sole proprietors are treated as natural persons at the $10,000 limit.
Can I appeal a small claims court decision in Washington?
Only when the amount in controversy exceeds $1,000 under RCW 12.36.020. Either party can appeal a Washington Small Claims judgment to the Superior Court within 30 days. The appeal is heard on the record made in District Court, not de novo. Below $1,000, the small claims judgment is final and non-appealable.
Washington small claims at a glance
Washington enforces a strict no-attorney rule in small claims under RCW 12.40.080: no lawyer or paralegal may participate in the prosecution or defense of a small claims action without the express consent of the judicial officer hearing the case. Corporations may only appear through a non-attorney employee. The two-tier limit separating natural persons at $10,000 from entity plaintiffs at $5,000 makes Washington one of the few states that deliberately favors individual access over corporate collection. RCW 12.40 has been amended several times since 2019 to expand small claims jurisdiction for natural persons. The 12% statutory post-judgment interest rate under RCW 4.56.110, or the Washington Treasurer rate if higher, is among the highest in the country and incentivizes prompt payment.
Filing cost example: $6,000 unpaid invoice
Suppose a client owes you $6,000 on a written services contract. The statute of limitations for written contracts in Washington is 6 years under RCW 4.16.040, so you must file within 6 years of the missed payment. Because you are a natural-person plaintiff, you can sue for the full $6,000 in the Small Claims Department under RCW 12.40.010 (entity plaintiffs are capped at $5,000). Filing fee is $50 statewide under RCW 12.40.020, plus a $30 to $50 sheriff service fee under RCW 12.40.040. After winning, post-judgment interest accrues at 12% per year under RCW 4.56.110. If the defendant pays in 30 days, you collect $6,000 plus filing and service fees. If unpaid for 1 year, you are owed roughly $6,720.

Frequently Asked Questions
RCW 12.40.010 sets a $5,000 limit for entities and $10,000 for natural persons. The split is a deliberate consumer-protection choice: it discourages debt buyers and collection agencies from using small claims as a high-volume collection forum while keeping access broad for individuals. The two-tier rule has been in effect since the 2019 amendments to Chapter 12.40.
The filing fee is $50 statewide under RCW 12.40.020. Sheriff service typically adds $30 to $50. There is no sliding scale by claim amount. Indigent plaintiffs can request a fee waiver by filing a Motion and Declaration for Waiver of Civil Fees and Surcharges, which waives both filing and service costs if approved.
Generally no. RCW 12.40.080 bars attorneys and paralegals from participating in small claims actions unless the judge expressly consents. Corporations must appear through a non-attorney officer or employee. The bar applies at the District Court level only; on appeal to Superior Court for claims over $1,000, attorneys are permitted under RCW 12.36.020.
Washington's statute of limitations is 6 years for written contracts under RCW 4.16.040, and 3 years for oral contracts, property damage, and personal injury under RCW 4.16.080. The clock starts on the date of breach or injury. Filing the Notice of Small Claim tolls the limitations period for that defendant from the date of filing.
After judgment, you can collect using writs of execution under RCW 6.17, wage garnishment under RCW 6.27, and bank levy. Judgments docketed in Superior Court create a real-property lien for 10 years under RCW 4.56.190. Post-judgment interest accrues at 12% per year or the Washington Treasurer rate, whichever is greater, under RCW 4.56.110.
Several Washington District Courts now accept electronic filing of the Notice of Small Claim through county-specific portals, but availability is not uniform statewide. The Washington Courts website at courts.wa.gov maintains a directory of e-filing-enabled District Courts. Most plaintiffs still file in person at the District Court clerk's office.
Yes. The defendant can file a counterclaim under RCW 12.40.050 within the small claims jurisdictional limit ($5,000 or $10,000 depending on entity status). If the counterclaim exceeds the limit, either party can move to transfer the case to the regular District Court civil docket. Counterclaim fees are the same $50 filing fee.
