Roundup Lawsuit Statute of Limitations: Your Deadline by State - and What Starts the Clock
Most states give Roundup (glyphosate) non-Hodgkin lymphoma claimants 2-3 years, a few only 1, some up to 6 or more - and in almost all of them the clock starts at diagnosis or discovery of the link, not the day you sprayed. Here is the full state list from our statute-of-limitations database, plus the 2026 settlement and Supreme Court wrinkles.

What Starts the Clock: the Discovery Rule
Roundup cases are product-liability claims, and nearly every state applies a discovery rule to latent injuries: the limitations period runs from when you knew - or reasonably should have known - of the injury and its likely cause, not from exposure. In practice the trigger is usually the NHL diagnosis, but defendants argue for earlier dates, often pointing to the March 2015 IARC classification of glyphosate as “probably carcinogenic” as the moment a reasonable person “should have known”. Where exactly a state draws that line is a fact question decided case by case - we found no single published Roundup ruling that settles it, so treat the diagnosis date as your safe anchor and get counsel to fix the rest.
Case Details
Wrongful-death claims run on their own clock - generally from the date of death - and many states give families a shorter window than the injured person had. Some states also impose a statute of repose (an outer limit measured from the product's sale) that can bar old exposures regardless of discovery. Both are reasons the state list below is a starting point, not a verdict.
2026: Settlement and Supreme Court Change the Calendar
Supreme Court: Monsanto v. Durnell (June 25, 2026, 7-2) held FIFRA preempts label-based failure-to-warn claims contrary to EPA's determination - which changes what you can claim, not when, but makes early legal review even more important.

How to Work Out Your Own Deadline
- 1
Fix the Diagnosis Date
Pathology and oncology records establish when NHL was diagnosed - the usual discovery-rule anchor.
- 2
Identify the Governing State
Usually where you were exposed or live; multi-state histories can offer a choice of forum with different windows.
- 3
Apply the State Rule - and Its Exceptions
Headline years above, then discovery rule, tolling (minority, incapacity), and any statute of repose.
- 4
Layer in the Class Settlement
If you are a class member, the settlement's registration and claim deadlines run from final approval (hearing Sept 14, 2026) and appeal conclusion.
- 5
File Well Inside the Window
Evidence (receipts, witnesses, employer records) decays faster than deadlines; counsel will also want time to evaluate your claim post-Durnell.
Three Deadline Mistakes
The clock is unforgiving - avoid these:
Counting from the last time you sprayed
That is exposure, not discovery. In most states the clock starts at diagnosis - but defendants will argue earlier, so do not assume generosity either.
Assuming the class settlement pauses everything
Tolling doctrines exist, but the settlement has its own registration and claim deadlines, and opt-out already closed June 4, 2026. Get the official notice.
Treating the table as legal advice
Headline years hide discovery rules, repose and tolling. A one-line statute does not decide your case - a lawyer applying it to your dates does.
Roundup Statute of Limitations - FAQ
What is the statute of limitations for a Roundup lawsuit?
It depends on the state: most allow 2-3 years, Kentucky/Louisiana/Tennessee 1 year, Florida/Nebraska/Wyoming 4, Missouri 5, Maine/Minnesota/North Dakota 6, Rhode Island 10 - generally counted from discovery (diagnosis), not exposure.
When does the clock start - exposure or diagnosis?
Under the discovery rule that nearly all states apply to latent injuries, from when you knew or should have known of the injury and its likely cause - usually the NHL diagnosis. Defendants may argue an earlier 'should have known' date (e.g., after IARC's 2015 classification); courts decide case by case.
Does the $7.25B settlement extend my deadline?
It creates its own: reported 180 days after final approval (hearing Sept 14, 2026) to register and 180 days after appeals to claim. General class-action tolling may also apply, but verify with counsel - opt-out closed June 4, 2026.
What if the person who used Roundup has died?
The wrongful-death statute applies, generally from the date of death, and in some states it is shorter than the injury window (1 year in KY, LA, TN).
I was diagnosed years ago - is it too late?
Possibly, but not certainly: tolling, the exact discovery date, the governing state and the class settlement all matter. Have a firm run the analysis - consultations are free.
Did the Supreme Court ruling change the deadline?
No - Durnell (June 25, 2026) changed which claims are viable (preempting label-based failure-to-warn where EPA said no cancer warning was needed), not the limitations clock.
Which states have the shortest Roundup deadlines?
One year for product-liability claims: Kentucky, Louisiana, Tennessee. Florida and several others are 2-4 years; check the list above for yours.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
