It’s a bright-line deadline for filing a lawsuit claim

It serves as a complete bar to suit

(i.e., it’s a threshold inquiry)

It is an affirmative defense

Must plead in answer

It varies by state and kind of action

Analogous equitable doctrines are laches and estoppel

For equity, it’s not a bright-line deadline. Instead, it’s essentially a fairness inquiry. Reliance can be important.

Federal statutes often borrow state limitations.

It’s a legal malpractice trap!

Deterioration of evidence

Avoiding the re-ignition of conflicts quieted by time

Peace of mind for potential defendants

Ability to throw out trash

Promotes forward-looking investments

Avoids costs to society through increased insurance costs

Social value of stable transactions and relationships

Having a claim one day but not the next is irrational

Bars otherwise just claims

Inflexible

Prevents some kinds of torts from being compensable at all

Note: These examples could be out-of-date! Check the up-to-date law!

While the statute of limitation is ostensibly a bright-line deadline, there are some key flexibilities:

When the statute starts running

When it is tolled

(i.e., when the clock is put on pause)

Which statute applies

Control over these variables introduces room for courts to tailor the application of the law to conceptions of fairness.

It depends on what rule is applicable in a given jurisdiction.

Accrual rule

Harm (rather than act)

When damage is done and you can sue

Discovery rule

When relevant facts are discovered (or should have been discovered by the reasonable person)

E.g., foreign object left by surgeon

These are “time outs” on the running of the limitation period.

Reasons might include:

Minority age

Military service

Mentally incompetent

Prison

Another suit pending on the same matter

Prerequisite administrative proceedings

Defendant’s agreement

These are outside time limits that run from the act.

The “act” can vary by state. For negligence, it’s probably the breach. For product defects, the statute might run from manufacture date, first sale, or first use.

The duration depends on the state. Some examples:  5 years, 10 years, 12 years, 15 years, 20 years, “the expiration of the ordinary useful life of the product.”

As a baseline/fallback, if the act is more than 20 years in the past, you can figure the statute of repose is likely a claim-killer. But in some states, the claim could still be viable.

Even if you are within the statute of limitations, your claim might still be barred by the statute of repose.

Defendants helped include product manufacturers, engineers, architects, physicians.

But you never know!

You have to check a jurisdiction’s particular law.

Interestingly, in 2025 a court noted:

"No statute of repose exists for product liability claims under New York law.”

Francis v. Johnson & Johnson No. 22-cv-3812 (ALC) (S.D.N.Y. Nov. 24, 2025) (cleaned up)

Example: You buy a vintage 1950s blender at a garage sale. You get injured by a product defect of the blender that same day and immediately sue the manufacturer.

Will the manufacturer have a winning statute of limitation or statute of repose defense?

The statute of limitations will not bar your claim. But the statute of repose likely will.

Example: On Monday Bob buys a 12-year-old car seat (automotive baby safety seat) from a thrift store. A reasonable thrift store wouldn’t sell such old car seats. Because of an outdated design, currently counting as a product defect, the car seat injures Bob’s baby on Tuesday. If the baby sues the thrift store for strict products liability and negligence, does the store have a good statute of limitations or statute of repose defense?

The statute of limitations won’t bar either claim. The statute of repose won’t bar the strict product defect claim if the statute of repose starts running from the defendant’s act, but it could if it runs from manufacture, first sale, or first use. The statute of repose shouldn’t bar the negligence claim.
