Data last reviewed: October 2026. General information, not legal advice.
Illinois law requires written contract plaintiffs to file suit within 10 years of the date of breach, as established by 735 Ill. Comp. Stat. 5/13-206. Failing to file before this deadline will almost certainly result in the court dismissing your case — regardless of how strong your evidence is or how clear the defendant's liability may be.
The clock for written contract claims typically starts on the date the breach occurred — when the other party failed to perform a contractual obligation. Some states use an "accrual" rule (when you knew or should have known of the breach) rather than the strict breach date.
Illinois has one of the longest written contract periods in the US at 10 years.

The 10-year deadline in Illinois applies to the following types of written contract claims:
If your claim falls outside these categories, a different statute of limitations may apply. An attorney can confirm which deadline governs your specific situation.
Compile the original contract, all amendments, addenda, and related correspondence. Contract terms control your rights and remedies.
Determine exactly when the other party failed to perform. This is typically when the statute of limitations clock starts.
Record every loss caused by the breach: unpaid amounts, mitigation costs, lost profits, and other provable damages.
A written demand gives the breaching party an opportunity to cure and creates a record. Some contracts require a formal cure period before suit.
Many contract disputes resolve without litigation. Consider mediation, especially if an ongoing business relationship exists.
If resolution fails, file in court before the limitations period expires. Courts are strict — even one day late can be fatal to your claim.

No state-specific exceptions are formally documented for this claim type in Illinois, though general tolling rules for minors and mental incapacity may still apply. Consult an attorney.
If you miss the 10-year deadline, the defendant will file a motion to dismiss based on the expired statute of limitations. Courts virtually always grant such motions. Your case will be dismissed with prejudice — meaning permanently — regardless of how strong your evidence is. Always consult an attorney as soon as possible after an injury.
The standard rule in Illinois starts the clock on the date of breach. A discovery rule modification may apply in limited circumstances. Consult an attorney if you believe the standard start date is unfair in your situation.
Illinois's 10-year deadline for written contract claims is tied for the longest in the country. Across all states and D.C., written contract deadlines range from 3 years to 10 years.
If a city, county, state agency, or other government entity is responsible, you typically must file a Notice of Claim with the agency within a much shorter period — often 60–180 days. Missing this notice requirement can permanently bar your claim even before the main statute of limitations expires. Consult an attorney immediately if any government entity is involved.
Possibly, but it is difficult. You would need to demonstrate that a tolling doctrine applies — such as the discovery rule, minority tolling, or fraudulent concealment. An attorney can evaluate whether any exception extends your deadline. Do not assume your claim is dead until you have spoken with a licensed Illinois attorney.
