How to Join a Mass Tort Lawsuit

If you have been harmed by a defective product, dangerous drug, or toxic exposure, joining a mass tort lawsuit may allow you to seek compensation. The process is simpler than most people expect, especially because experienced attorneys handle the legal complexity for you — at no upfront cost. This guide walks you through each step.

Overview: The 5-Step Process

Joining a mass tort involves five main stages. While the legal proceedings can take years, your active involvement is primarily in the early stages — getting informed, consulting an attorney, and providing your case details.

Step 1: Research Your Situation

Before contacting an attorney, it helps to understand the basics of the lawsuit relevant to your situation. Key things to research:

• What product or exposure is involved? Identify the specific drug, device, chemical, or product that harmed you.
• Who qualifies? Most mass torts have specific eligibility criteria based on timing of exposure, type of injury, and geographic location.
• What is the current status? Is the lawsuit in early stages, MDL, bellwether trials, or settlement negotiations?
• Are there filing deadlines? Statutes of limitations and specific program deadlines may apply.

You can start by reviewing our active lawsuit pages, which provide detailed eligibility criteria, timelines, and current status for each case. For a broader understanding of the process, see our guide on how mass tort lawsuits work.

Step 2: Consult a Mass Tort Attorney

Once you believe you may qualify, the next step is a free case evaluation with a mass tort attorney. During this consultation:

• The attorney reviews the facts of your situation to determine if you have a viable claim
• You describe your exposure or use of the product, your diagnosis, and your treatment history
• The attorney explains the legal process, timeline, and what to expect
• You can ask questions about fees, your rights, and the likelihood of success

This consultation is free and creates no obligation. If the attorney believes you have a strong case, they will offer to represent you on a contingency basis. You can request a free case review here.

Step 3: File Your Claim

If the attorney agrees to take your case, they handle the legal filing process. This includes:

• Drafting the complaint: The legal document outlining your claims against the defendant(s)
• Filing in the appropriate court: Your attorney determines whether to file in federal or state court
• MDL transfer (if applicable): If an MDL exists for your type of case, your claim may be transferred to the consolidated proceeding
• Serving the defendant: The defendant is formally notified of your lawsuit

You do not need to appear in court during this stage. Your attorney handles all paperwork, court filings, and communications with the defense.

Step 4: Discovery and Litigation

Discovery is the process by which both sides gather evidence. This is typically the longest phase and includes:

• Document requests: Obtaining internal company documents, emails, and research data from the defendant
• Medical records: Your attorney collects your medical records, treatment history, and expert medical opinions
• Depositions: Sworn testimony from witnesses, experts, and company executives
• Expert reports: Scientists, doctors, and other experts provide opinions on causation and damages

During discovery, your primary responsibility is to provide medical records and other documentation your attorney requests. You may be asked to complete a Plaintiff Fact Sheet (PFS) — a standardized form used in MDLs to detail your exposure, injuries, and medical history.

Step 5: Wait for Resolution

Most mass tort cases are resolved through one of three paths:

1. Global settlement: The defendant agrees to pay a total sum to resolve all or most claims. Payouts are distributed based on a tier system that accounts for injury severity. This is the most common outcome.
2. Individual settlement: In some cases, your attorney may negotiate a separate settlement for your specific claim, particularly if your injuries are severe.
3. Trial verdict: If a settlement cannot be reached, your case may go to trial. Bellwether trials in the MDL often set the stage for broader settlement negotiations.

What You Need to Get Started

To prepare for your free case evaluation, gather as much of the following information as you can. Do not worry if you do not have everything — an attorney can still evaluate your case with limited information.
