What Proof Do You Need For Roundup Lawsuits? (March 2025)

What Is the Roundup Lawsuit About?

The multidistrict litigation (MDL) around Roundup began in 2016. The lawsuits allege that Bayer/Monsanto knew that Roundup could increase the risk of non-Hodgkin’s lymphoma and failed to warn consumers.

Since the start of the Roundup lawsuit, tens of thousands of plaintiffs have filed lawsuits against Bayer/Monsanto. In early trials, the company awarded one plaintiff $80 million and another pair of plaintiffs, a couple, $2.055 billion.

Bayer has settled thousands of additional cases, and some have gone to trial. The litigation is ongoing, and there are tens of thousands of cases remaining.

You might wonder — what is the average payout for Roundup lawsuit plaintiffs? Given the fact that cases vary in terms of cancer severity, it’s difficult to determine an average settlement amount. Roundup lawsuit updates indicate that while Bayer/Monsanto is still settling cases, some are going to trial.

Multimillion-dollar verdicts may be the ones that make the news, but most plaintiffs do not recover nearly as much. Some experts estimate that settlements usually range from $5,000 to $250,000, and that the average settlement is around $160,000.

What Proof Do You Need for Roundup Lawsuits?

If you’ve been diagnosed with cancer after a chemical exposure to Roundup, you might be unsure of whether you have sufficient proof to win a case. Only a lawyer can answer that question for sure, but it may be helpful to know the types of evidence that can be helpful in a lawsuit:

A Qualifying Cancer Diagnosis

To join the Roundup lawsuit, you must have one of the cancers that have been linked to glyphosate through research. Non-Hodgkin’s lymphoma is the most common, but these are some of the other qualifying diagnoses:

• B-cell lymphoma
• Follicular lymphoma
• Mantle cell lymphoma
• T-cell leukemia
• T-cell lymphoma

This list is not an exhaustive one. If you have a cancer diagnosis and aren't sure if it qualifies, an experienced lawyer should be able to tell you.

Proof That You Regularly Came Into Contact With Roundup

Some people exposed to Roundup purchased it for their own use. Others were employed by farms and other businesses that required regular use of the product. Depending on your unique situation, proof of contact with Roundup may include one or more of the following:

• Receipts showing you purchased Roundup
• Photos of Roundup containers
• Bank statements reflecting purchases of Roundup
• Proof of employment with a particular company
• A statement from the employer that you regularly used Roundup as part of your job duties

If you aren’t sure how to contact an old employer, don’t automatically assume you’re ineligible for the lawsuit. An attorney may be able to reach a former employer or otherwise recover the proof you need.

Witness Testimony

In some cases, witness testimony might be necessary to strengthen your case. For example, if you purchased Roundup for your own use, your friends and neighbors might be able to testify that they saw you use it regularly. If you worked for a landscaping company that used the product, your boss and coworkers could verify the fact that Roundup usage was a regular part of the job.

Because the defendants may try to argue that your exposure was too insignificant to cause harm, establishing the fact that you were frequently in contact with Roundup is critical.

Expert witnesses might be a part of your case as well. Oncologists and other medical experts may be able to state why they believe Roundup, and not another environmental toxin, was responsible for your diagnosis.

Most law firms handling Roundup lawsuits are already connected to expert witnesses who are familiar with the harms of glyphosate, so finding expert witnesses is not likely to be difficult.

Proof of Negligence

Your attorney is responsible for proving Bayer/Monsanto acted negligently. This involves breaching a duty of care toward the public to provide reasonably safe products with adequate warnings.

Attorneys have already discovered that the company ghostwrote studies to “prove” that Roundup was safe and posed no cancer risk, and Bayer/Monsanto’s internal communications have revealed that the company knew about the risks and actively hid them.

How Do You Prove Roundup Caused Your Cancer?

Many people know or reasonably suspect that their diagnosis of non-Hodgkin’s lymphoma was caused by Roundup exposure. However, many also aren’t quite sure how to prove it. While it’s always wise to keep your medical bills and any proof that you purchased Roundup, you don’t have to figure out how to prove the cause of your cancer on your own.

The best way to ensure you have as much proof as possible is to consult an experienced attorney. The right lawyer can help you find the evidence you need, and if you qualify to join the Roundup lawsuit, they can also help you file the appropriate paperwork.
