Statute of limitations on debt in Washington
In Washington, a creditor or debt collector has 6 years to sue on a written contract, 3 years on an oral agreement, and 6 years on an open account such as a credit card (RCW 4.16.040 (written contracts and accounts receivable, 6 yrs); RCW 4.16.080(3) (contracts not in writing, 3 yrs)). For medical bills, the operative number is 6 years — Washington has no medical-debt-specific limitations period; an unpaid medical bill is an 'account receivable' (an obligation incurred in the ordinary course of the provider's business) under RCW 4.16.040(2), and bills tied to signed service/admission agreements are written contracts under RCW 4.16.040(1) — both carry 6 years, so 6 years applies either way.
| Written contracts | 6 years |
| Oral agreements | 3 years |
| Open accounts (credit cards) | 6 years |
| Medical debt | 6 years |
How the limitation works
- It limits lawsuits, not the debt. A time-barred debt still exists; what expires is the collector’s ability to win in court.
- It is a defense you must raise. Courts don’t apply it for you. If you are sued and don’t respond, the collector wins by default — even on a time-barred debt.
- The clock usually runs from last activity — typically your last payment — not from when the debt was sold. A debt buyer inherits the original clock.
- Threatening to sue on time-barred debt is illegal. Federal Regulation F (12 C.F.R. §1006.26) bars collectors from suing or threatening suit on time-barred debt, whether or not they knew it was time-barred.
The restart trap
Yes — under RCW 4.16.270 any payment of principal or interest restarts the limitations period from the date of the last payment, and under RCW 4.16.280 a written, signed acknowledgment or promise also revives the claim.This is the single most expensive mistake people make with old debt: a small “good-faith” payment on a nearly-expired account can hand the collector a fresh lawsuit window. Confirm the dates before paying anything on an old account.
What to do with an old collection notice
- Find the date of last activity — your own bank records beat the collector’s letter.
- Count forward using the table above. Older than the period? The debt may be time-barred in Washington.
- Send a written validation request — it forces the collector to document the debt and pauses collection until it does (15 U.S.C. §1692g). Generate it free →
- Do not acknowledge the debt in writing or pay anything until you know where the clock stands.
- If you’re sued, respond by the deadline and raise the statute of limitations. Your state’s legal aid can help free: Washington State Office of the Attorney General, Consumer Protection Division.
Washington’s own collection law
The Washington Collection Agency Act (Ch. 19.16 RCW (prohibited practices at RCW 19.16.250)) The Collection Agency Act licenses collectors and debt buyers and prohibits harassment, misrepresentation, unauthorized fees, and suing on unlicensed debt (RCW 19.16.260); violations are automatically unfair practices under the Consumer Protection Act, ch. 19.86 RCW, giving consumers treble-damages claims. Yes — collection agencies and debt buyers must be licensed by the Washington State Department of Licensing under RCW 19.16.110, and an unlicensed agency may not maintain a collection lawsuit (RCW 19.16.260).
Common questions
What is the statute of limitations on debt in Washington?
Washington allows 6 years to sue on written contracts, 3 years on oral agreements, and 6 years on open accounts such as credit cards (RCW 4.16.040 (written contracts and accounts receivable, 6 yrs); RCW 4.16.080(3) (contracts not in writing, 3 yrs)). Medical debt is generally treated as a written contract here — 6 years.
When does the clock start?
Generally from the date of default or last activity on the account — commonly the last payment or charge — not from when the debt was sold to a collector. Selling a debt does not reset the statute of limitations.
Does paying something on an old debt restart the statute of limitations in Washington?
Yes — under RCW 4.16.270 any payment of principal or interest restarts the limitations period from the date of the last payment, and under RCW 4.16.280 a written, signed acknowledgment or promise also revives the claim.
Can a collector still contact me about a time-barred debt?
Yes — the statute of limitations limits lawsuits, not requests to pay. However, under federal Regulation F (12 C.F.R. §1006.26), a collector may not sue or threaten to sue on a time-barred debt — the ban applies whether or not the collector knew the debt was too old.
What should I do if I get sued on an old debt?
Respond by the court deadline — never ignore a summons, because a default judgment revives everything. If the debt is older than the limitations period, raise the statute of limitations as an affirmative defense in your answer. Many defendants win on this alone.
How is a judgment different?
Once a creditor wins a judgment, a separate and much longer enforcement period applies, and judgments can often be renewed. That is why responding before judgment matters more than anything else on this page.
