Washington Statute of Limitations on Debt: How Long Can You Be Sued?

In Washington, a creditor or debt collector generally has six years to file a lawsuit on most consumer debts based on a written contract or an open account, and only three years to sue on a purely oral agreement. These deadlines come from Washington's statutes of limitation, primarily RCW 4.16.040 (six years for written contracts and accounts receivable) and RCW 4.16.080 (three years for oral contracts). Once the applicable period runs out, the debt does not disappear, but you gain a complete legal defense: if you are sued after the deadline and you raise the expired statute of limitations in court, the case should be dismissed.

How long Washington gives creditors to sue

The clock you face depends on the type of debt and how it is documented:

• Written contracts — 6 years. Under RCW 4.16.040, any action on a contract in writing, or a liability arising out of a written agreement, must be filed within six years. Signed loan agreements and installment contracts fall here.
• Credit cards and open accounts — 6 years. RCW 4.16.040 also gives a six-year limit to actions on an "account receivable." Washington courts have generally treated credit-card debt and revolving accounts as subject to the six-year period rather than the shorter oral-contract period.
• Promissory notes — 6 years. A signed promissory note is a written contract. For negotiable instruments, Washington's Uniform Commercial Code (RCW 62A.3-118) sets a six-year limit running from the note's due date or, for demand notes, from the date demand is made.
• Oral (unwritten) contracts — 3 years. Under RCW 4.16.080, an action on a contract or liability not founded on a written instrument must be brought within three years.

Because most consumer credit involves a signed agreement or a documented account, the six-year period is the one that applies in the great majority of debt-collection lawsuits in Washington.

When the clock starts

The limitation period generally begins to run when the creditor's claim "accrues" — in plain terms, when you default and the creditor has the right to sue. For a credit card or open account, that is typically your last payment or the date the account first became delinquent and was not cured. For an installment loan, each missed payment may have its own accrual date, and acceleration of the full balance can start the clock on the entire debt.

Pinning down the exact accrual date matters, because it determines whether a lawsuit filed years later is timely or barred. Old account statements, the original agreement, and your payment history are the documents that establish that date.

The critical trap: payment or acknowledgment can restart the clock

This is the single most important rule for Washington consumers to understand. The six- or three-year period is not always fixed from your original default. Two things can restart it from zero:

• Making a partial payment. Under RCW 4.16.270, when a payment of any part of the principal or interest has been made on an existing debt, the limitation period commences again from the time of that last payment. A single small payment on an old, nearly time-barred account can revive the creditor's right to sue for years.
• A written, signed acknowledgment or new promise. Under RCW 4.16.280, an acknowledgment or new promise to pay restarts the clock only if it is in writing and signed by the person to be charged. A casual verbal statement that you "owe" the money generally is not enough on its own — but do not rely on that as a strategy.

Because of these rules, debt collectors sometimes contact consumers about very old debts hoping to obtain a small payment or a written admission that resets the deadline. Before you pay anything or sign anything on an old account, confirm whether the statute of limitations has already expired. Paying even a few dollars on a time-barred debt can hand the collector a fresh six years to sue.

An expired statute of limitations is a defense you must raise

In Washington, an expired statute of limitations is an affirmative defense. That means it does not stop a lawsuit from being filed, and the court will not apply it for you automatically. You must assert it yourself, in writing, in your formal answer to the lawsuit. If you ignore the summons or fail to plead the defense, the court can enter a default judgment against you even on a debt that is decades old — and that judgment can then be enforced through wage garnishment or bank levy.

If you are served with a debt-collection complaint:

• Do not ignore it. Note the deadline to respond, which is typically stated on the summons.
• File a written answer and specifically raise the statute of limitations as a defense if the debt appears time-barred.
• Make the plaintiff prove the dates. A collector suing on a purchased debt must be able to show when the account went into default and that the suit was filed within the limitation period.
• Consider consulting a consumer attorney or a legal-aid program, especially before agreeing to any settlement that includes a payment.

How Washington compares to federal law

State law sets the deadline to sue, but federal law adds important protections. The federal Fair Debt Collection Practices Act (FDCPA) applies to third-party debt collectors and prohibits abusive and deceptive practices. Federal regulators have made clear that suing or threatening to sue on a debt the collector knows is time-barred can violate the FDCPA, and the Consumer Financial Protection Bureau's collection rule (Regulation F) bars collectors from suing or threatening suit on time-barred debt. If a collector takes you to court on an expired Washington debt, you may have both a state defense and a federal claim.

Washington reinforces these protections with its own laws: the Washington Collection Agency Act (RCW 19.16), which regulates collectors operating in the state, and the Consumer Protection Act (RCW 19.86), which can provide remedies for unfair or deceptive collection conduct. Note that an expired statute of limitations is separate from how long a debt can appear on your credit report; that is governed by the federal Fair Credit Reporting Act (FCRA), which generally allows most negative items to be reported for up to seven years.

Where to verify and get help

Because case law and statutory citations can change, and because the right deadline depends on the specific facts of your account, verify before you act. The Washington State Attorney General's Office, Consumer Protection Division publishes consumer guidance on debt and collections and accepts complaints against collectors who break the rules. You can also read the statutes themselves — RCW 4.16.040, RCW 4.16.080, RCW 4.16.270, and RCW 4.16.280 — on the Washington State Legislature's official website. For help responding to a lawsuit, contact a licensed Washington consumer attorney or a civil legal-aid organization such as the statewide CLEAR legal-aid line.

The bottom line: most Washington consumer debts must be sued on within six years (three for oral agreements), the clock can restart if you make a payment or sign an acknowledgment, and an expired deadline only protects you if you show up in court and raise it.
