What Is the Discovery Rule? When the Statute of Limitations Actually Starts

| by Dean Venizelos

Most people who read a page like this one have already looked it up once. You typed your state into a search bar, found a number, did the arithmetic, and closed the tab. You arrived at an answer that felt final, and you have been carrying it ever since as a settled fact.

Wherever you are in your survivor journey, that is okay. But a single number found online is very rarely the whole answer.  And being told a deadline has passed is not the same thing as it having actually passed. This page will not tell you your claim is alive; nobody can without knowing your facts. It explains how the timing rules actually work, including the parts that are less favorable than survivors are often led to believe, so you can ask a better question of someone who can answer it properly.

The Assumption Worth Questioning

The assumption almost everyone starts with is that the clock began on the day the abuse happened, and that once enough years passed, the matter closed permanently. For survivors who were children at the time, that is usually wrong at the first step. In most states the clock does not run against a child at all; it is paused, or tolled, until the survivor turns 18. That mechanism, minority tolling, is separate from everything else on this page, and a great many people do their arithmetic from the wrong starting year.

There is not one deadline question. There are several, operating independently, and a survivor only needs one of them to work: whether the clock was paused during childhood, whether the state uses a fixed age deadline, whether a discovery rule applies to when the clock started, whether the state has opened a window reviving expired claims, and whether the state has removed the deadline outright.

How the Discovery Rule Works

Where it applies, the discovery rule delays the start of the clock. Rather than running from the date of abuse, the clock begins when the survivor knew, or reasonably should have known, of the injury and its connection to what happened to them. The phrase doing the heavy lifting is “reasonably should have known,” and the standard is objective rather than personal: a court asks what a reasonable person in that survivor’s circumstances would have understood, and when. That is why these disputes tend to turn on records and the sequence of events rather than on how a survivor describes their own experience.

The doctrine was built with three situations in mind: the memory of the abuse was unavailable to the survivor for a period of time; the abuse was always remembered but its connection to later harm was not understood until much later; or the abuse involved a trusted authority figure, which may bear on when a survivor could reasonably have recognized it as wrongful. Washington has written this into statute specifically for childhood sexual abuse, with legislative findings that a survivor may repress the memory of abuse or be unable to connect it to any injury until after the ordinary deadline has run. If your question is more about why disclosure took as long as it did, our article on grooming and delayed disclosure [LINK TBD] addresses that directly.

Where the Rule Is Strong and Where It Is Narrow

The delayed discovery rule is real, but it is not uniform. Some legislatures have written a discovery rule specifically for childhood sexual abuse, the most favorable version. Other courts have required something close to a genuine inability to recall the abuse, rather than a delayed understanding of its effects, which is a meaningful limitation for many survivors who always remembered what happened. In some jurisdictions the doctrine reaches certain causes of action and not others. And in the most important, least discussed category, where a legislature has removed the filing deadline entirely or opened a revival window, the discovery rule may no longer be the argument that decides anything – a good development, and one reason this doctrine is less central today than fifteen years ago, when it was often a survivor’s only available argument.

Why the Defendant Changes the Answer

The deadline for a claim against the person who committed the abuse and the deadline for a claim against the institution responsible for putting that person in a position of trust are not always the same, and in some states they are meaningfully different. In at least one state, delayed discovery has been treated as available against a perpetrator while allegations of repressed memory have been held not to delay the clock against an institutional defendant. In another, survivors have a long period to sue the individual while claims against an institution fall under a much shorter general deadline.

If you were once told a claim against an individual had expired, you may not have been told anything about a claim against the institution behind them, and the reverse can also be true. Where an organization’s own failures contributed to what happened, our article on reporting failures and institutional responsibility [LINK TBD] covers how those claims are built.

The Other Ways Survivors Get Through the Door

Over the past decade, legislatures rather than courts have done most of the work here. Minority tolling pauses the clock until 18 in most states, as a baseline survivors do not have to argue for. Some states set a fixed age instead of a period of years: California, for abuse before 2024, generally allowed claims until a survivor’s fortieth birthday or five years from discovery, whichever came later, while Michigan generally requires filing before the twenty-eighth birthday. Two states, two very different answers.

The more significant development is permanent elimination of the deadline. Roughly twenty states, two U.S. territories, and the federal government have eliminated the civil filing deadline for some or all childhood sexual abuse claims, and roughly forty-four states plus the federal government have no criminal deadline at all. Vermont eliminated its civil deadline in 2019, retroactively, reaching institutional defendants as well as individuals. Nevada did so permanently and retroactively in 2021. Delaware and Maine have eliminated it as well, and the federal Eliminating Limits to Justice for Child Sex Abuse Victims Act of 2022 removed the deadline for federal child sex abuse claims.

Revival windows are temporary reopenings that allow already-expired claims to be filed for a limited period; roughly thirty states, the District of Columbia, and three territories have used them at some point, and several are open right now. California’s Assembly Bill 250, the Justice for Survivors of Sexual Assault Act, opened a two-year window running from January 1, 2026 through December 31, 2027, for survivors who were 18 or older at the time of assault, reaching both perpetrators and private institutions while excluding public entities – distinct from California’s earlier Assembly Bill 218 window for childhood abuse claims, which closed December 31, 2022. New York City amended its Gender-Motivated Violence Act in January 2026 to open an eighteen-month window running through July 29, 2027. Louisiana’s window runs through June 13, 2027 and Mississippi’s through June 30, 2027.

One limit is worth knowing: revival is not available everywhere, since some state constitutions have been read to prevent reviving already-expired claims, on the reasoning that a defendant acquires a protected interest once a deadline runs. A survivor cannot assume that because a neighboring state opened a window, their own state can do the same. If your question is what might change next rather than what applies today, our article on state survivor rights legislation moving in 2026 [LINK TBD] covers the bills currently in play.

How Expert Testimony Supports a Discovery Rule Argument

Where a delayed start has to be argued rather than assumed, expert testimony often does the work. The expert’s task is narrower than survivors sometimes expect: they are generally not asked to prove abuse occurred, but to help a court understand when a survivor could reasonably have recognized the connection between the abuse and their injuries. Records that tend to carry weight include therapy and counseling records around the period when understanding shifted, the timing of a first disclosure to anyone, relevant medical history, and the specific event that preceded a survivor’s recognition of the link. Defendants contest this testimony as a matter of course and admissibility standards vary, but nobody is expected to have understood any of this alone or to arrive already holding proof of it. Assembling that record is the lawyer’s job, not the survivor’s.

Why It Can Still Be Worth Asking Early

There is no correct time to be ready, and nobody should file before they want to. Still, several open revival windows expire on fixed dates in 2027, and once they close, the claims they revived may be barred again permanently. What a claim is worth can also change even where the deadline is gone – Maryland eliminated its filing deadline in 2023, had that law upheld by its Supreme Court in a closely divided February 2025 decision, and then amended the Act in 2025 to reduce available damages for claims filed after a later date that year. And evidence simply does not improve with time, as witnesses move or die and institutional files are sometimes destroyed on ordinary retention schedules.

Frequently Asked Questions

Can I still sue for childhood abuse that happened decades ago? – In some states, yes, without qualification, because the deadline has been eliminated retroactively. In others it depends on your age, the year, the claim type, and the defendant.

Does the discovery rule apply if I always remembered what happened? – Sometimes. States diverge sharply here; some accept that a survivor may have remembered the events while not understanding their connection to later harm, while others require something closer to an actual inability to recall.

I was told years ago that my deadline had passed. Is that still true? – Possibly not. Roughly twenty states have eliminated the civil deadline and roughly thirty have opened revival windows at some point, much of it since 2019. An opinion from before then was given under a different set of laws.

Is the deadline the same for suing an institution as for suing the person who abused me? – Not necessarily, and this is one of the most commonly misunderstood points in this area. An answer about one may say nothing about the other.

What happens if the institution has filed for bankruptcy? – Bankruptcy changes the process considerably and usually imposes its own separate, often earlier, deadlines. If you believe an organization connected to your case has filed, that is worth raising early.

We Are Here to Hear Your Story

We are here to hear your story, including the part where you already looked this up once and concluded the answer was no. Constant Legal Group (CLG) evaluates every situation individually, because general rules are exactly what this area of law does not have. What applies to you depends on where the abuse happened, when, who else may have been responsible, and how the law in that state has changed since. Those are answerable questions, and answering them does not commit you to filing anything.
