The statute of limitations for breach of fiduciary duty usually runs somewhere between two and six years, but the exact deadline depends on your state, the kind of fiduciary involved, and whether you’re asking for money or an equitable remedy like removing a trustee.1Justia. Civil Statutes of Limitations 50-State Survey Retirement plan claims are the big exception: those run on a federal clock, not a state one. Whatever deadline applies to you, it’s strict. Missing it almost always ends the case no matter how strong the evidence is.
What Determines Your Deadline
Three variables push the number up or down.
The first is your state. Legislatures set their own limitations periods, and the spread across the country is wide. Some states cap fiduciary claims at two years; others allow six or more.
The second is the remedy you want. Suing for money to cover a financial loss is often classified as a property injury claim and gets a shorter window. Asking a court to undo a transaction, remove a dishonest trustee, or impose a constructive trust is equitable relief, and equitable claims often carry a longer deadline. The same misconduct can produce two different deadlines depending on what you ask the court to do about it.
The third is the nature of the wrong. A claim built on fraud typically gets a longer filing window than one built on negligent mismanagement, because fraud is harder to detect and the law gives victims more time to find it.
When the Clock Starts Running
The deadline doesn’t necessarily begin on the day the fiduciary acted badly. Most states use a “discovery rule” that delays the start until you knew or reasonably should have known about the harm. That matters a lot in fiduciary relationships, because the whole arrangement rests on trusting someone else to handle your affairs. You aren’t expected to audit your own fiduciary.
“Reasonably should have known” is measured objectively. Courts ask what an attentive person in your position would have noticed. If your trustee mails you an annual statement showing unexplained withdrawals or strange fees, the clock may start when that statement lands in your hands, whether or not you opened the envelope.
Some jurisdictions go further and delay the clock until the fiduciary’s “open repudiation” of the relationship, meaning a clear, visible act that signals to the beneficiary that something has gone wrong. Until that happens, the filing period can stay dormant. This is one of the sharpest differences between fiduciary claims and ordinary contract disputes.
Continuous Representation
When the fiduciary is a professional like an attorney, accountant, or financial advisor, another timing rule can push the start date later. Under the continuous representation doctrine, the statute of limitations may not begin until the professional finishes work on the specific matter where the breach happened. The reasoning is practical: while they’re still on the job, you have little reason to second-guess their work.
Courts draw this narrowly. Tolling applies to the specific transaction at issue, not to the broader ongoing relationship. If your attorney mishandled a real estate closing in January but you later hired the same attorney for an unrelated contract dispute in June, the clock on the real estate claim started when that particular engagement ended.
ERISA: A Separate Federal Deadline for Retirement Plans
If your claim involves a retirement plan fiduciary, such as a 401(k) plan administrator or investment manager, federal law replaces state law. The Employee Retirement Income Security Act uses two clocks: you must file within three years of gaining actual knowledge of the breach, or within six years of the breach itself, whichever comes first.2Office of the Law Revision Counsel. 29 USC 1113 Limitation of Actions
The three-year clock requires “actual knowledge,” which the U.S. Supreme Court has interpreted strictly. You must personally be aware of the facts constituting the breach. Constructive knowledge, where a court decides you should have known based on available information, does not start this clock.
The six-year outer deadline is different. It runs from the date of the breach itself, regardless of whether you ever learned about it. The one exception is fraud or concealment: when a fiduciary actively hides the breach, the six-year period resets and runs from the date you actually discover the fraud.2Office of the Law Revision Counsel. 29 USC 1113 Limitation of Actions
What Can Pause the Clock
Once the deadline starts running, certain events can pause it. Lawyers call this “tolling.”
Fraudulent Concealment
If your fiduciary takes active steps to hide the breach, the clock pauses until you discover the fraud or could have discovered it with reasonable effort. The key word is “active.” Staying quiet about misconduct may not be enough. Fabricating records, destroying evidence, or lying about the status of your accounts almost certainly is. The clock resumes once the cover-up unravels or should have.
Legal Incapacity
If the wronged person is a minor or has been judicially declared mentally incompetent, the deadline is typically paused until the disability ends. For minors, that usually means the clock starts on their 18th birthday. Federal law extends similar protection to claims against the United States, giving an additional period after the disability ceases.3Office of the Law Revision Counsel. 28 USC 2401 – Time for Commencing Action Against United States
Active Military Service
The Servicemembers Civil Relief Act pauses the statute of limitations for the entire period of active military service, whether the servicemember is the potential plaintiff or the defendant.4Office of the Law Revision Counsel. 50 USC 3936 – Statute of Limitations The time in service is simply excluded from the deadline calculation.
Statutes of Repose: The Absolute Backstop
A statute of repose is not the same as a statute of limitations, and mixing them up can cost you the case. A statute of limitations starts when you discover the harm (or should have) and can be paused by tolling. A statute of repose starts from a fixed event, usually the date of the breach, and cannot be paused for any reason. No discovery rule, no tolling for fraud, no exceptions for incapacity. When it runs out, the claim is dead.
ERISA shows how the two work together. The three-year deadline triggered by actual knowledge behaves like a traditional statute of limitations. The six-year deadline from the date of the breach behaves like a statute of repose, and it applies even if you never learned about the misconduct. The only carve-out is for fraud or concealment.2Office of the Law Revision Counsel. 29 USC 1113 Limitation of Actions
Many states have their own statutes of repose covering professional relationships and financial transactions. The specific cutoff varies, but the principle is the same: after enough time passes from the triggering event, finality wins.
Laches: A Second Timing Risk
Filing within the statute of limitations doesn’t automatically save an equitable claim. A separate doctrine called laches can still bar the case. Laches applies when you’re seeking equitable relief such as removing a trustee, reversing a transaction, or imposing a constructive trust, rather than money damages.
To win on laches, the defendant has to prove two things: that you unreasonably delayed filing, and that the delay caused them real prejudice. Prejudice can be lost evidence, faded memories, changed financial positions, or reliance on the existing state of affairs. Delay alone isn’t enough. A defendant who suffered no harm from your wait can’t use laches to escape the claim.
Courts often use the analogous statute of limitations as a benchmark. File after that period expires, and the delay is presumed unreasonable, shifting the burden to you to explain it. File before, and the defendant bears the heavier burden. The upshot is that being technically within the deadline isn’t always enough if you sat on the claim after learning about the breach.
What Happens if You File Late
The statute of limitations is an affirmative defense. A court won’t dismiss your case on timing grounds on its own; the defendant has to raise it.5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading They almost always do, because it’s one of the most powerful tools in litigation. If the court agrees the deadline has passed, the case is over.
Once a claim is time-barred, the right to sue is effectively extinguished. The strength of your evidence, the size of your loss, and the seriousness of the breach are all irrelevant to the procedural question of whether you filed on time. Judges apply these deadlines mechanically and have almost no discretion to override them.
If you suspect a fiduciary has breached their duty, the safest move is to talk to a lawyer early. The specific deadline that governs your situation depends on facts an attorney can pin down quickly, and once the clock has run there is usually nothing left to do about it.
