A limitation period runs quietly and it can end a good claim

The most important sentence on this site

If you think you might have a claim, find out how long you have to bring it, and do it now rather than after the correspondence has run its course. Limitation periods are the mechanism by which entirely valid claims are lost, and they are lost quietly, without anybody sending a warning.

This is not a marginal risk. Complaints processes, internal appeals, insurer negotiations and simple hope all consume months, and none of them ordinarily stops the clock. People discover the deadline at the point where an adviser tells them it passed some time ago, and there is generally nothing to be done about it.

Why systems impose time limits at all

The reasons are practical rather than punitive. Evidence decays: documents are destroyed under retention policies, witnesses move and die, and memories become unreliable long before either. A dispute litigated many years after the events is decided on materially worse information than one brought promptly.

There is also a fairness argument about finality. A person or business cannot arrange their affairs sensibly while facing indefinite exposure to claims about things done long ago, and at some point the interest in certainty is treated as outweighing the interest in allowing every claim to be heard. Different systems strike that balance in different places, which is why the periods differ so widely.

Working out when the clock started is the hard part

The length of a period is usually easy to look up. When it began is where the difficulty sits. Depending on the claim and the jurisdiction, time may run from the breach itself, from the date damage occurred, from the date the claimant knew or should reasonably have known about it, or from some other defined event.

That knowledge-based approach exists because some harms are not apparent when they happen — a latent defect in a building, a professional error whose consequences emerge years later, an injury with a delayed onset. Many systems soften the rule for such cases, and many then impose a long-stop date beyond which no claim can be brought however late the discovery. Both halves of that arrangement matter.

Things that pause, extend or restart the clock

Several circumstances commonly affect the running of time. Periods often do not run against children until they reach adulthood, and there are frequently provisions for people who lack the capacity to bring a claim. Acknowledgement of a debt, or a part payment, can restart the period in many systems, which is a detail that surprises debtors and creditors equally.

Parties can sometimes agree to suspend time while they negotiate, usually through a formal written agreement rather than an understanding. Where a mandatory complaints process or an alternative dispute route applies, some jurisdictions pause the clock during it and others do not, and assuming the generous answer is a serious risk. Different claims arising from the same facts can also carry different periods, so a single event may produce one route that is still open and another that has closed.

Deliberate concealment is the other common qualification. Where a defendant has hidden the facts that would have revealed the claim, many systems postpone the start of the period until the concealment could reasonably have been discovered, on the basis that a wrongdoer should not benefit from having covered their tracks. The threshold is usually high and it is not met merely because the claimant did not think to ask. It is worth raising with an adviser where the facts fit, but it is no substitute for acting promptly.

What being out of time actually means

In many systems expiry does not extinguish the underlying right so much as bar the remedy, meaning the other side has to raise it as a defence — which they will. In others it extinguishes the claim outright. Either way the practical result is the same, and courts have limited discretion to extend, usually confined to particular categories of claim.

The consequence is stark enough to be worth stating plainly. A claim that would certainly have succeeded is worth nothing once it is out of time. No amount of documentation, sympathy or obvious fault by the other side changes that, and it is the most avoidable loss in the whole of civil dispute resolution.

How to find out yours

The periods are jurisdiction-specific, they differ by type of claim, they are amended from time to time, and this article deliberately names none of them. A number read on a website that turns out to describe another country is worse than no number, because it produces false confidence.

Ask a qualified lawyer or a competent advice service in your own jurisdiction, describe the claim and the dates, and ask specifically when the period began and when it ends. That conversation is usually short and often free, and it is the first call to make rather than the last. If the deadline is close, say so at the outset, because it changes what any adviser will recommend doing first.
