A letter arrives about a credit card you stopped paying years ago, and the balance has somehow grown. An old debt can still end in a judgment, and then in a wage garnishment, if you ignore the summons. California gives most creditors and collectors four years to file suit on a written agreement or a consumer account, and after that the law bars the case. But no one checks the calendar for you. If you do not answer in writing and raise the deadline as a defense, the court can enter judgment anyway. Our California debt collection defense attorneys at The Fullman Firm work to keep old claims from becoming collectible judgments.
When the Four-Year Clock Starts and When It Runs Out
California’s limitations statute for written agreements is Code of Civil Procedure Section 337. It gives four years to bring an action on a contract, obligation, or liability founded on an instrument in writing. The same period covers a book account, which is an account based on a detailed record of debits and credits kept in the regular course of business between a debtor and creditor.
One of those routes recently narrowed. Section 337a defines what a book account is for this purpose. Since January 2024, it states that a book account does not include consumer debt, meaning an obligation incurred on or after July 1, 2024 for personal, family, or household purposes where the duty to pay appears in a note or written contract. For newer consumer accounts, a collector can no longer package the claim as a book account.
A shorter period applies when nothing was put in writing. Section 339 gives two years for a contract, obligation, or liability not founded on an instrument of writing. It is subject to exceptions the statute names, including the four-year period the Commercial Code sets for breach of a contract for the sale of goods.
The start date is where most online summaries get loose. Section 312 allows an action only within the prescribed period after the cause of action accrued, but it does not supply the accrual date for your account. Section 337 fixes one. It states that for an account stated built from more than one item, time runs from the date of the last item. Beyond that, no California statute sets a single accrual date for a consumer account, so treat confident claims that the clock always starts on your last payment with caution.
What an Expired Deadline Actually Stops
Once the applicable period has run, three separate rules can apply, and they do not all reach the same companies.
State Law Bars the Lawsuit Itself
Section 337 provides that when the period under that section has run, a person shall not bring suit or initiate an arbitration or other legal proceeding to collect the debt. That language is not limited to collection agencies.
Debt Buyers
Under California’s fair debt buying statutes, a debt buyer may not bring suit or initiate an arbitration or other legal proceeding to collect a consumer debt once the applicable limitations period has expired. A debt buyer is a person or entity regularly in the business of buying charged-off consumer debt for collection, and those rules cover debt sold or resold on or after January 1, 2014.
Federal Rule
Regulation F prohibits a debt collector from bringing or threatening to bring a legal action against a consumer to collect a time-barred debt, apart from a proof of claim in a bankruptcy. That definition turns on collecting debts owed to another and excludes activity concerning a debt the collector originated, so a lender pursuing its own account can fall outside the rule.
Each ban is broad in a different direction. The Section 337 bar covers the widest range of companies, because it speaks to any person rather than to agencies alone. The other two are not tied to the four-year period, so they can also reach a stale two-year claim that Section 337 never touches.
What Can and Cannot Restart the Clock
Section 337 says its four-year period may only be extended under Section 360, which is where the acknowledgment and payment rules live. These rules include:
- A signed writing counts. No acknowledgment or promise takes a case out of the limitations rules unless it is contained in some writing signed by the party to be charged.
- A payment on a promissory note counts. A payment of principal or interest due on a promissory note, made by the party to be charged, is treated as an acknowledgment that stops the period and starts a new one.
- A payment by itself does not raise the dead. That same sentence ends with an express limit: no such payment of itself shall revive a cause of action once barred.
- A signed waiver is a separate trap. Section 360.5 makes a waiver of the limitations defense effective only in a writing signed by the person obligated. It runs no more than four years, but it can be renewed successively.
Section 360 is not the only provision that can move a deadline. Other sections in the same title stop the clock while a defendant is out of state, or while an injunction or statutory prohibition blocks the filing. Official court self help guidance also tells consumers, more simply, that a payment made after four years of inactivity restarts the period.
That summary sits in tension with statutory text tying the payment rule to promissory notes and denying revival of a claim already barred. Treat the point as unsettled rather than settled, and get advice before you send a collector money on an old account.
Why Time-Barred Debt Still Turns Into Judgments
An expired deadline is a defense, not an automatic dismissal, and nothing prevents a stale claim from being filed. California does require a debt buyer’s complaint to allege the date of default or the date of the last payment, so the facts that decide timing often appear on the face of the complaint.
Raising the defense is your job. Section 458 lets you plead the deadline without pleading the underlying facts. You may state generally that the cause of action is barred by the provisions of the Code of Civil Procedure section, and the subdivision, you rely on. It also adds the other half of the bargain. If the plaintiff disputes your allegation, you must establish at trial the facts showing the claim is barred.
The window is short. A California summons must direct the defendant to file a written response within 30 days after it is served. It must also warn that a default will be entered on the plaintiff’s application, which could result in garnishment of wages and the taking of money or property. Undoing a judgment afterward takes a motion to vacate a default judgment rather than a phone call.
How to Protect Yourself When an Old Debt Resurfaces
A few habits preserve the defense long enough for someone to use it.
- Keep every document and write down the service date. The 30 day period runs from service, so the day the papers reached you is what everything else is measured against.
- Build your own timeline before you argue about theirs. Your last statement, your last payment, the charge-off date, and anything you signed decide when the period started and whether anything restarted it.
- Respond in writing, on time, in the right court. The state courts publish step by step instructions on how to answer a debt collection lawsuit, including the forms and the fee waiver.
- Do not send a payment or sign anything to buy time. A writing you sign is what the statute treats as an acknowledgment; a payment on a note can start a new period, and a signed waiver can hand back the defense outright.
If a lawsuit has already been filed, the response deadline is the first thing to check and the first thing worth a lawyer’s eyes.
