A strong legal claim can become worthless for one simple reason: it was filed too late. Every type of civil claim has a deadline, known as a statute of limitations. Once that deadline passes, the court or arbitrator will usually dismiss the case no matter how clear the evidence is.
Many people do not realize a deadline applies until they finally decide to act. Understanding how these time limits work can protect your right to recover.
What Is a Statute of Limitations?
A statute of limitations is a law that sets the maximum amount of time you have to start a legal action. The clock generally begins when the harm occurs or when you discover it.
These deadlines exist for practical reasons:
- Evidence fades and witnesses’ memories become less reliable over time
- Defendants deserve some certainty that old disputes will not resurface indefinitely
- Courts benefit from resolving disputes while the facts are still fresh
Common Deadlines by Type of Claim
Time limits vary by state and by claim type. Some typical ranges include:
- Personal injury: Often 2 to 3 years, though some states allow less or more
- Medical malpractice: Often 1 to 3 years, sometimes with a separate outer limit
- Written contracts: Commonly 4 to 6 years, and longer in some states
- Property damage: Often 2 to 5 years
- Federal antitrust claims: 4 years from when the cause of action accrued
- Claims against government entities: Frequently require a formal notice within months, not years
Because the rules differ so much, the specific deadline for your situation should always be confirmed with an attorney.
When Does the Clock Start?
The start date is not always obvious. Several legal doctrines can affect it:
The discovery rule. In some cases, the clock starts when you knew, or reasonably should have known, about the harm rather than when it happened. This often applies in medical malpractice and fraud cases.
Continuing violations. When harmful conduct is ongoing, such as repeated overcharges, each new act may restart the clock for that particular harm. Damages may still be limited to what occurred within the limitations period.
Tolling. Certain events pause the clock, such as the injured person being a minor, the defendant leaving the state, or a pending class action covering the same claims.
Contracts Can Shorten Your Deadline
Many people are surprised to learn that a contract can impose a shorter deadline than the law would otherwise allow. Insurance policies, employment agreements, and online terms of service sometimes require claims to be brought within one year or less.
Business owners should pay particular attention to this. Platform agreements for software, payment processing, and advertising often contain dispute resolution sections with their own notice and filing requirements. For example, businesses that believe they were overcharged for Google Ads following recent federal antitrust rulings need to consider both the antitrust limitations period and the arbitration terms in Google’s advertising agreement.
Signs You Should Act Quickly
You should speak with a lawyer promptly if:
- You were injured and are still receiving treatment
- You discovered a financial loss that may have been caused by someone else
- A company has admitted fault or been found liable in a related case
- You received a settlement offer and are unsure whether to accept it
- You are not sure which state’s law applies
What Happens if You Miss the Deadline?
In most cases, a claim filed after the deadline will be dismissed. The other side must usually raise the statute of limitations as a defense, but they almost always do.
There are limited exceptions, such as fraud that concealed the harm, but courts apply them narrowly. Relying on an exception is risky.
Protect Your Rights Early
The safest approach is to treat every potential claim as time-sensitive. Gather your documents, write down key dates, and consult an attorney before the deadline becomes a problem. An early conversation costs little, while a missed deadline can cost you the entire claim.
