Roundup Lawsuit Filing Deadlines by State
Every state has a statute of limitations — a legal deadline — for filing a Roundup lawsuit. Whether that time has passed depends on your facts, so don't rule yourself out. A lawyer can tell you. Most states apply a "discovery rule" that starts the clock when you learned (or should have learned) that Roundup may have caused your cancer.
The Discovery Rule: When Does the Clock Start?
For most Roundup cases, the statute of limitations does not start when you were first exposed to Roundup or even when you were diagnosed with cancer. Instead, it starts when you discovered — or reasonably should have discovered — that Roundup may have caused your cancer. For many people, this was after the IARC classification in 2015 or after the Johnson verdict in 2018 brought widespread media attention to the cancer link.
A farmer diagnosed with NHL in 2020 learns about the Roundup-cancer link from a TV news report in 2024
In most states, the statute of limitations starts in 2024 when the farmer first connected Roundup to their cancer, not in 2020 when they were diagnosed.
A landscaper who used Roundup for 15 years is diagnosed with DLBCL in 2023
The discovery rule means the deadline starts from the 2023 diagnosis date (when the harm became known), not from when exposure began. In a state with a 2-year SOL, they would have until 2025 to file.
A homeowner who sprayed Roundup in their garden was diagnosed with follicular lymphoma in 2019 but didn’t learn about the lawsuit until 2025
Courts may consider when a reasonable person would have connected Roundup to their cancer. Given the extensive media coverage since 2018, a court might find the clock started earlier than 2025. An attorney can explain how the deadline applies.
If you used Roundup and have been diagnosed with non-Hodgkin lymphoma or another cancer, a lawyer can check your filing deadline. Whether that time has passed depends on your facts, so don't rule yourself out. A lawyer can tell you.
This table provides general guidance. Actual deadlines depend on your specific circumstances, including when you discovered the connection between Roundup and your cancer. An attorney can determine your exact deadline.
