Statute of Limitations vs. Statute of Repose: What's the Difference?
They sound similar and are easily confused, but a statute of repose can bar your claim even before you know you were harmed. Here's how the two deadlines differ.

If you’ve researched filing deadlines, you may have run into a confusing pair of terms: statute of limitations and statute of repose. They both set time limits on lawsuits, but they work in fundamentally different ways — and the difference can decide whether your claim survives.
Statute of limitations: the clock starts when you’re harmed
A statute of limitations runs from when your claim accrues — usually the date of the injury, or under the discovery rule, the date you knew or should have known about it. This is the deadline most people mean when they ask “how long do I have to sue?”
Because it can be tied to discovery, a statute of limitations is somewhat flexible: if you couldn’t reasonably have known about the harm, the clock may not have started yet.
Statute of repose: an absolute outer deadline
A statute of repose is harder-edged. It runs from a fixed event — the date a product was sold, a building was completed, or medical care was provided — regardless of when the harm occurs or is discovered. Once it expires, the claim is gone, even if you were injured the day before and had no way to know earlier.
In other words: a statute of repose can bar a claim before the statute of limitations clock even starts.
A quick example
Imagine a product with a 10-year statute of repose from the date of sale, and a 2-year statute of limitations from the date of injury:
- If the product injures you in year 3, you have 2 years from that injury to sue. Fine.
- If it injures you in year 11, the 10-year repose period has already expired — and you may be barred no matter how recent the injury.
Which claims have both?
Statutes of repose most often appear in:
- Medical malpractice (frequently a few years beyond the limitations period)
- Product liability (tied to the date of first sale)
- Construction defects (tied to substantial completion)
Because repose periods are unforgiving and vary widely by state, this is an area where confirming the rule with an attorney is especially important. Start by checking your state’s standard period on the deadline calculator, then read what a statute of limitations actually is for the full picture.
