Roundup Lawsuit Statute of Limitations: How Long Do You Have to File?

What Is the Statute of Limitations?

The statute of limitations is the legal deadline by which a lawsuit must be filed. In civil litigation, including product liability claims like the Roundup lawsuit, every state imposes a deadline after which you lose your right to pursue compensation — regardless of how strong your case may be.

In Roundup cases, the statute of limitations typically begins to run from the date you were diagnosed with Non-Hodgkin Lymphoma, or from the date you discovered (or reasonably should have discovered) that your cancer may be linked to Roundup exposure. Once the clock starts, missing the deadline is almost always fatal to your claim — courts virtually never grant extensions once the limitations period has expired.

This is why legal professionals emphasize: if you believe you have a Roundup claim, do not wait. The sooner you consult with an attorney, the better positioned you are to protect your rights.

Statute of Limitations by State

Statutes of limitations for product liability and personal injury claims vary by state. The following table summarizes the general deadlines in major states — but these are general rules, and exceptions can apply. Always confirm the current law with a licensed attorney:

Note: These are general product liability deadlines. The actual deadline in your case depends on when the clock started (see the discovery rule below), your specific state's current law, and any applicable exceptions or tolling rules.

The Discovery Rule: When Does the Clock Start?

In most states, the statute of limitations does not necessarily start running on the date of your NHL diagnosis. Instead, it may start from the date you discovered — or reasonably should have discovered — that your cancer may have been caused by Roundup. This is called the 'discovery rule,' and it can be critically important in Roundup cases.

For example, if you were diagnosed with NHL in 2018 but did not learn until 2021 that Roundup may have caused your cancer, the discovery rule may extend your filing deadline to 2023 (in a two-year state). Courts examine what information was publicly available and when a reasonable person in your position would have connected their diagnosis to Roundup exposure.

The IARC's 2015 carcinogenicity classification and the widespread media coverage of early Roundup trial verdicts in 2018 and 2019 are often used as reference points for when knowledge of the Roundup-NHL connection became reasonably accessible. If you were diagnosed before that period, the discovery rule may be particularly relevant to your case.

Circumstances That May Pause the Clock

Several legal doctrines can pause (or "toll") the statute of limitations clock, potentially extending the time you have to file:

• Fraudulent concealment: If Bayer/Monsanto actively concealed information about glyphosate's risks that prevented you from discovering your potential claim, courts may toll the limitations period for the duration of that concealment
• Minority: If the claimant was a minor at the time the cause of action arose, most states toll the statute of limitations until the claimant reaches age 18
• Mental incapacity: If the claimant was legally incapacitated, tolling may apply
• Discovery during active litigation: If you were part of an MDL or other coordinated proceeding, tolling orders may apply to claims within that proceeding
• Wrongful death: In cases where a claimant has died, the wrongful death statute of limitations may run from the date of death rather than the date of diagnosis

Whether any of these tolling doctrines apply to your specific situation is a legal question that requires an attorney's analysis.

Does the Roundup MDL Affect My Deadline?

The Roundup litigation has been consolidated in a Multidistrict Litigation (MDL) in federal court in the Northern District of California for coordinated pretrial proceedings. The existence of an MDL does not automatically toll your statute of limitations. Individual claimants still need to file their claims within the applicable deadline, or risk losing their rights.

Some attorneys file a protective complaint within the MDL or in state court to preserve their clients' claims while settlement negotiations proceed. If you are represented by an attorney in an existing MDL proceeding, your deadlines should be monitored by your legal team. If you are unrepresented, you should act quickly to avoid being time-barred.

It is important to understand that mass tort settlements do not automatically include everyone who may have a claim. If you have not yet been formally enrolled in any settlement or filed a lawsuit, your rights are not automatically protected.

Why You Should Act Now

The statute of limitations is not a technicality — it is a hard legal deadline that courts enforce strictly. Unlike some procedural rules that courts may bend in the interest of justice, statutes of limitations are rarely extended once they expire. Missing the deadline by even one day can permanently extinguish your right to compensation.

Given the complexity of determining which deadline applies to your specific case, and the potential for the discovery rule and tolling to affect that calculation, the safest course is to consult with an attorney as soon as possible. A free case evaluation takes only a few minutes and can give you clarity on whether you still have time to file and what your options are.

If you or a loved one used Roundup and was later diagnosed with Non-Hodgkin Lymphoma, do not assume your window has closed without speaking with an attorney first. Many claimants who thought they had missed the deadline have been able to file valid claims through the discovery rule or other tolling doctrines.
