Illinois Statute of Limitations on Debt: Time Limits by Type

The statute of limitations on debt sets how long a creditor or debt collector has to file a lawsuit to collect what someone owes. In Illinois, the deadline depends on the type of debt, and it can reset if a payment or a written promise to pay is made after the account defaults. This article is part of Illinois consumer protection laws and how they are enforced. It covers the specific time limits, when the clock starts, what restarts it, and how the deadline works if a collector files suit.

How long a creditor has to sue on debt in Illinois

Illinois sets the limitation period by the kind of obligation, not by the dollar amount. Three periods cover most consumer debt.

Written debts get the longest window. Under 735 ILCS 5/13-206, actions on written contracts, promissory notes, written leases, and other written evidence of indebtedness must be brought within 10 years after the cause of action accrues.

Oral and unwritten debts get a shorter window. Under 735 ILCS 5/13-205, actions on unwritten contracts, whether express or implied, must be commenced within 5 years. This 5-year period also catches most open accounts that are not backed by a signed written agreement.

Debts for the sale of goods follow the Uniform Commercial Code. Under 810 ILCS 5/2-725, an action for breach of a contract for sale must be commenced within 4 years after the cause of action accrues, and the parties may shorten that period by agreement to as little as one year but may not extend it.

A related but separate deadline applies to claims under the Illinois Consumer Fraud and Deceptive Business Practices Act, which carry a 3-year limitation period under 815 ILCS 505/10a. That period governs a consumer’s own fraud claim against a seller, not a creditor’s suit to collect a debt.

Written debts, oral debts, and credit cards

The line between a written debt and an unwritten one decides whether the 10-year or the 5-year period applies, and it is not always obvious. A written contract is one where the essential terms, the amount, the parties, and the promise to repay, appear in a signed writing. When those terms have to be supplied from outside the document, Illinois courts have generally treated the obligation as unwritten and applied the 5-year period in 735 ILCS 5/13-205.

Credit card debt is the common source of confusion. Because a cardholder agreement is often not a single signed document setting every term, Illinois courts have generally applied the 5-year unwritten-contract period to credit card balances that lack a signed written agreement. Where a signed written contract does govern the account, the 10-year written-contract period in 735 ILCS 5/13-206 can apply instead. The distinction turns on the paperwork behind the specific account.

When the clock starts and what restarts it

The limitation clock generally starts when the cause of action accrues, which for most consumer debt is the date a required payment is missed and the account goes into default. From that date, the applicable 10-, 5-, or 4-year period runs.

Two kinds of events can restart the clock. Under 735 ILCS 5/13-206, if a payment or a new promise to pay is made in writing on a written debt, a fresh 10-year period runs from the date of that payment or promise. The federal Consumer Financial Protection Bureau describes the same trap more broadly: making a partial payment or acknowledging that an old debt is owed may restart the time period, even after the original limitation period has run.

Figuring out the deadline on a specific debt follows a consistent sequence.

1. Identify the type of debt

   Written contracts, promissory notes, and other signed written agreements fall under the 10-year period. Oral agreements and open accounts without a signed contract fall under the 5-year period. A contract for the sale of goods falls under the 4-year period.

2. Find the date of last activity

   The clock generally starts when a required payment is missed and the account goes into default. Locate the date of the last payment or the first missed payment on the account statements.

3. Add the statutory period

   Count forward from that date: 10 years for written debt, 5 years for oral or unwritten debt, and 4 years for goods. The result is the approximate date by which a collector must file suit.

4. Check for events that restarted the clock

   A payment or a written promise to pay made after default can restart the period under 735 ILCS 5/13-206. Note any later payments, written settlement offers, or written acknowledgments of the debt.

What happens when the statute of limitations runs out

A debt that is past its limitation period is called time-barred. The period bars the lawsuit, not the debt. As the CFPB explains, a debt does not generally expire or disappear until it is paid, and a collector can still contact a consumer about a time-barred debt through letters or calls as long as the contact otherwise follows the law.

What a collector cannot do is sue or threaten to sue on a time-barred debt. Filing or threatening a lawsuit on a debt that is past the limitation period violates the federal Fair Debt Collection Practices Act. A consumer sued on a time-barred debt may have both a defense to the collection case and a claim against the collector for the FDCPA violation, according to the CFPB’s guidance on old debts.

Because the limitation period runs from the date of last activity in Illinois, and because a payment can restart it, an old balance that a collector reports as recently active is worth checking against the consumer’s own records.

Raising the statute of limitations as a defense

The statute of limitations is an affirmative defense. That means the court will not apply it automatically; the person being sued has to raise it. If a defendant does not appear and point out that the deadline has passed, a court may still enter a judgment on a time-barred debt.

In a collection suit, the defense is raised in the written answer to the complaint and shown with evidence, such as records establishing that there has been no activity on the account for longer than the applicable period. The CFPB notes that it is ordinarily the responsibility of the person being sued to raise an expired statute of limitations. A defendant who ignores the lawsuit gives up the chance to use the defense at all.
