- Frequently Asked Questions About Mass Tort Eligibility
Mass tort litigation now represents roughly half of the entire federal civil docket. As of 2026, approximately 199,684 cases are pending across 158 active multidistrict litigation (MDL) dockets. The stakes are enormous. Settlements in recent years have reached billions of dollars. But eligibility is never automatic.
This mass tort eligibility guide walks you through every requirement. You will learn the five core criteria attorneys use to screen cases. You will see which active lawsuits are accepting new claims. You will understand how deadlines, documentation, and state laws affect your rights. If you believe you have a claim, this is where to start.
Understanding Mass Tort Eligibility: The Five Core Criteria
Every mass tort eligibility guide begins with the same foundation. Courts and attorneys evaluate potential claimants against five core criteria. Meeting all five does not mean you will receive compensation. But failing any one of them typically disqualifies a claim.
A mass tort is a civil action where many plaintiffs sue one or a few defendants. Each plaintiff must prove individual harm. This is different from a class action, where one representative sues on behalf of the entire group.
1. Product Use or Exposure
You must prove you actually used the product or were exposed to the substance. This is the most basic requirement. For pharmaceutical cases, you need prescription records. For toxic exposure cases, you need proof you lived or worked in the affected area. Military service records matter for cases like Camp Lejeune and AFFF.
2. Qualifying Medical Diagnosis
You must have a documented medical diagnosis. The diagnosis must match a condition linked to the product or substance. Not every health problem qualifies. Courts rely on epidemiological studies to determine which conditions are causally connected. Your diagnosis must appear in your medical records.
3. Causation
Scientific evidence must support a link between the product and your injury. Expert testimony is required under the Daubert standard. If a court excludes the plaintiffs’ causation experts, the entire MDL can collapse. This happened in the Tylenol/autism MDL (MDL 3043), which was dismissed in August 2024.
4. Sufficient Exposure or Dose
Courts increasingly require proof of adequate exposure. For the AFFF lawsuit, you must demonstrate exposure to PFAS-contaminated water. For hair relaxer cases, studies show that four or more uses per year significantly elevated cancer risk. Casual or minimal exposure may not meet the threshold.
5. Timely Filing
Your claim must fall within the applicable statute of limitations. These deadlines vary by state and by claim type. Missing the deadline usually means your claim is permanently barred. A licensed attorney can evaluate whether the discovery rule extends your filing window.
Mass Tort Eligibility Guide: Product and Exposure Requirements
The first step in any mass tort eligibility guide is confirming product use or exposure. This seems straightforward. In practice, it can be the hardest element to prove. Documentation is everything.
| Case Type | Required Exposure Proof | Common Documentation |
|---|---|---|
| Pharmaceutical (e.g., Roundup, Ozempic) | Confirmed product use during relevant period | Prescriptions, purchase receipts, applicator logs |
| Toxic exposure (e.g., Camp Lejeune, AFFF) | Residence or employment at contaminated site | Military records, utility bills, employment records |
| Medical device (e.g., hernia mesh, IVC filters) | Implantation of specific device | Surgical records, device identification cards |
| Consumer product (e.g., hair relaxer, talc) | Regular use over time | Purchase history, personal testimony, photographs |
| Environmental (e.g., Paraquat) | Occupational or residential exposure | Employment records, proximity data, licensing records |
For Camp Lejeune claims, exposure means living or working at the base for 30 or more days between 1953 and 1987. For Roundup claims, regular use of glyphosate-based herbicides is required. Each case has specific exposure windows and thresholds.
Medical Diagnosis Requirements in This Mass Tort Eligibility Guide
A qualifying diagnosis is central to every mass tort eligibility guide. You cannot file a claim based on fear of future illness alone. You need a confirmed diagnosis from a medical professional. That diagnosis must be documented in your medical records.
Different MDLs recognize different qualifying conditions. Here are the diagnoses courts and attorneys look for in the largest active cases.
| MDL / Lawsuit | Qualifying Diagnoses |
|---|---|
| Roundup (MDL 2741) | Non-Hodgkin lymphoma and related subtypes |
| AFFF / PFAS (MDL 2873) | Kidney cancer, testicular cancer, thyroid cancer, liver cancer, ulcerative colitis |
| Camp Lejeune (CLJA) | Bladder cancer, kidney cancer, non-Hodgkin lymphoma, Parkinson’s disease, liver cancer, leukemia |
| Hair Relaxer (MDL 3060) | Uterine cancer, endometrial cancer, ovarian cancer |
| Talcum Powder (MDL 2738) | Ovarian cancer, mesothelioma |
| Paraquat (MDL 3004) | Parkinson’s disease |
| Ozempic / GLP-1 (MDL 3094) | Gastroparesis, intestinal obstruction, ileus |
| Semaglutide Vision (MDL 3163) | Non-arteritic anterior ischemic optic neuropathy (NAION) |
| NEC Baby Formula (MDL 3026) | Necrotizing enterocolitis in premature infants |
| Hernia Mesh (MDL 2846) | Mesh migration, organ perforation, chronic pain, infection, bowel obstruction |
The Ozempic MDL (MDL 3094) has an additional requirement. The presiding judge requires plaintiffs to provide an objective gastric emptying study to confirm gastroparesis. Self-reported symptoms alone are not enough. This kind of evidentiary threshold is becoming more common in mass tort litigation.
Mass Tort Eligibility Guide to Active MDL Cases in 2026
This section of our mass tort eligibility guide covers the largest active MDL dockets. The Judicial Panel on Multidistrict Litigation (JPML) reported approximately 199,684 pending actions across 158 active dockets as of early 2026. These cases are concentrated in just 45 federal courts.
The top 22 dockets — those with 1,000 or more cases — account for 93.58% of all MDL actions. You can view the full list of active MDL cases on our tracking page.
| MDL No. | Case Name | Transferee Court | Pending Cases | Status |
|---|---|---|---|---|
| 2738 | Johnson & Johnson Talcum Powder | D. New Jersey | ~67,600 | Active — no global settlement |
| 2846 | Davol/Bard Hernia Mesh | S.D. Ohio | ~23,700 | Active |
| 2873 | AFFF Firefighting Foam (PFAS) | D. South Carolina | ~15,200 | Active — settlement anticipated |
| 3060 | Hair Relaxer Products | N.D. Illinois | ~11,400 | Active — first trials underway |
| 3004 | Paraquat Products | S.D. Illinois | ~6,580 | Master settlement signed Aug 2025 |
| 2741 | Roundup Products | N.D. California | ~3,900 | $7.25B class settlement pending |
| 3094 | Ozempic / Oral Semaglutide (GLP-1) | E.D. Pennsylvania | ~3,636 | Active — early discovery |
| 3047 | Social Media Adolescent Addiction | N.D. California | ~2,465 | Bellwether trial June 2026 |
| 3026 | NEC Baby Formula | N.D. Illinois | ~826 | Bellwethers set through 2027 |
| 3163 | Semaglutide Vision Loss (NAION) | E.D. Pennsylvania | Growing | New MDL — created Jan 2026 |
Camp Lejeune litigation is not a traditional MDL. All claims are filed directly in the Eastern District of North Carolina under the Camp Lejeune Justice Act (CLJA). Over 400,000 administrative claims were filed before the August 2024 deadline. Only about 2,353 settlements have been reached so far. Twenty-four jury trials are scheduled for 2026.
Understanding where your potential claim fits within these dockets is a critical part of any mass tort eligibility guide. A qualified mass tort attorney can evaluate whether your situation aligns with an active case.
How Statutes of Limitations Affect Your Mass Tort Eligibility
Filing deadlines are one of the most important topics in any mass tort eligibility guide. The statute of limitations sets the maximum time you have to file a claim. Miss it, and your case is likely over — regardless of how strong your evidence is.
These deadlines vary significantly by state and by claim type. Most personal injury claims have a two- to three-year window. Some states are shorter. A few are longer. Recent legislative changes have made this landscape even more complex.
| State | Personal Injury SOL | Notable Changes |
|---|---|---|
| California | 2 years | Discovery rule applies |
| New York | 3 years | Standard rule |
| Texas | 2 years | Standard rule |
| Florida | 2 years | Shortened from 4 years (HB 837, March 2023) |
| Illinois | 2 years | Standard rule |
| Louisiana | 2 years | Doubled from 1 year (mid-2024) |
| Utah | 4 years | Extended; repose extended to 8 years (HB 288, 2025) |
Check your state’s specific rules on our 50-state tort reform comparison page. You can also find detailed guides in our state tort reform directory.
The Discovery Rule
Most states apply the discovery rule to mass tort cases. The clock starts when you knew — or reasonably should have known — about your injury and its cause. This is critically important in latent-injury cases. Cancer from toxic exposure may not appear for years or decades. Without the discovery rule, many mass tort claims would be time-barred before the plaintiff even knew they were injured.
Statutes of Repose
Some states impose a statute of repose. This is an absolute deadline. It runs from the date of manufacture, sale, or last exposure. It cannot be extended by the discovery rule. These deadlines typically range from 6 to 12 years. They exist in roughly half the states.
Mass Tort Eligibility Guide: Documentation You Need
Strong documentation can make or break your claim. This mass tort eligibility guide emphasizes that evidence collection should start immediately. Do not wait until you hire an attorney. Begin gathering records as soon as you suspect a connection between a product and your injury.
| Document Type | Why It Matters | How to Obtain It |
|---|---|---|
| Medical records | Proves diagnosis and treatment timeline | Request from hospitals, clinics, specialists |
| Prescription history | Confirms product use and duration | Pharmacy records, insurance claims |
| Military service records | Proves location and dates of service | National Personnel Records Center (SF-180) |
| Employment records | Proves occupational exposure | Former employers, union records, OSHA logs |
| Purchase receipts | Proves consumer product use | Credit card statements, store records |
| Photographs | Shows injuries, products, or conditions | Personal collection, social media archives |
| Pathology reports | Confirms specific cancer type and staging | Treating hospital or oncologist |
For Camp Lejeune claims, the Department of the Navy requires proof of at least 30 days at the base. DD-214 forms and base housing records are the most common documentation. For Roundup claims, applicator logs, landscaping invoices, and photos of product use are valuable evidence.
Mass Tort Eligibility Guide to Recent Settlements and Verdicts
Understanding recent outcomes helps set realistic expectations. This mass tort eligibility guide includes 2025–2026 settlement data to show what qualifying claimants have received. Past results do not predict future outcomes. But they illustrate how mass tort settlements work in practice.
| Case | Settlement / Verdict | Key Details |
|---|---|---|
| 3M Combat Arms Earplugs | $6.01 billion total | Over $3.1B distributed; all 391,283 cases closed |
| Roundup (Bayer) | $7.25 billion class settlement | Preliminary approval March 2026; awards est. $6K–$165K |
| Camp Lejeune (CLJA) | $421 million+ paid | Elective Option offers: $100,000–$550,000 by tier |
| Paraquat | Master settlement signed | Average estimated $100,000–$150,000 per claimant |
| Philips CPAP | $1.1 billion PI settlement | Plus $479M class settlement; cancer claims ongoing |
| NEC Baby Formula | $495M verdict (Abbott) | Multiple state verdicts; no global MDL settlement yet |
| Zantac (GSK) | Up to $2.2 billion | State court settlements finalized June 2025 |
The 3M earplug settlement was the largest mass tort resolution by claimant count in U.S. history. The Roundup class settlement, if finally approved, would be one of the largest by total dollar amount. These outcomes show why understanding your eligibility matters.
Individual compensation varies widely. Settlement amounts depend on injury severity, strength of causation evidence, and exposure duration. Bellwether trials often set the benchmarks that drive settlement negotiations.
How Mass Tort Eligibility Differs from Class Action Qualification
Many people confuse mass torts with class actions. This mass tort eligibility guide draws a clear distinction. In a class action, one plaintiff represents the entire class. Members usually qualify automatically if they meet broad criteria. Individual proof of injury is not always required.
Mass torts work differently. Each plaintiff files an individual claim. Each must prove personal injury, product use, and causation. Compensation varies based on each person’s circumstances. There is no one-size-fits-all payout.
| Factor | Mass Tort | Class Action |
|---|---|---|
| Individual proof required | Yes — each plaintiff proves their case | No — class representative proves for the group |
| Compensation | Varies by individual injury and evidence | Usually uniform per class member |
| Attorney relationship | Direct attorney-client relationship | Class counsel represents the group |
| Opt-in required | Yes — you must actively file | Often opt-out (included unless you leave) |
| Eligibility screening | Detailed intake with medical record review | Broad criteria, often self-reported |
This distinction matters for eligibility. Mass tort claimants face a higher evidentiary bar. But they also have the potential for individually tailored compensation. That compensation reflects their specific injuries and losses.
State-by-State Factors That Affect Mass Tort Eligibility
Where you live — or where your injury occurred — affects your rights. This mass tort eligibility guide notes that state laws vary dramatically on key issues. Tort reform legislation has changed the landscape in many states over the past three years.
Key state-level factors include the statute of limitations, caps on damages, rules about expert testimony, and standards for proving causation. Some states are more favorable to plaintiffs. Others have enacted reforms that make filing harder.

Steps to Determine Your Eligibility: A Practical Mass Tort Eligibility Guide
This mass tort eligibility guide recommends following a specific sequence. These steps will help you assess whether you have a viable claim before contacting an attorney.
Step 1: Identify the product or exposure. Confirm that you used the specific product, took the specific drug, or were exposed to the specific substance at issue. General similarity is not enough. Brand names, formulations, and time periods all matter.
Step 2: Confirm your diagnosis. Review your medical records. Make sure your diagnosis matches one of the qualifying conditions for the relevant MDL. Ask your doctor to document the connection in writing if they believe one exists.
Step 3: Check the timeline. When were you exposed? When were you diagnosed? When did you first learn the product might be responsible? Compare these dates against your state’s statute of limitations. The discovery rule may extend your deadline.
Step 4: Gather documentation. Collect medical records, prescription histories, employment records, military service records, and any other evidence of exposure. The more documentation you have, the stronger your case will be.
Step 5: Consult a licensed attorney. A mass tort lawyer can evaluate your claim at no upfront cost. Most work on contingency — they only get paid if you receive compensation. An attorney can assess whether your claim meets the specific eligibility requirements for the relevant lawsuit.
Common Reasons Claims Are Denied: Mass Tort Eligibility Guide Warnings
Not every claim succeeds. This mass tort eligibility guide identifies the most common reasons claims are rejected or dismissed.
Insufficient exposure proof. You used the product, but you cannot document it. Without records, receipts, or corroborating evidence, your claim may not survive initial screening.
Non-qualifying diagnosis. Your health condition is real. But it is not one of the conditions linked to the product in the MDL. Courts rely on specific epidemiological evidence. Only certain diagnoses qualify for each case.
Causation failure. The science does not support a connection between the product and your injury. This is what happened in the Tylenol/autism MDL (MDL 3043). The court excluded plaintiffs’ causation experts. The case was dismissed in August 2024. An appeal was argued at the Second Circuit in November 2025.
Missed deadline. You filed after the statute of limitations expired. In Camp Lejeune litigation, the CLJA imposed a hard two-year filing deadline. It expired on August 10, 2024. Over 117,000 claims were filed in time. Those who missed the deadline are likely permanently barred.
Alternative cause. The defendant argues your injury was caused by something else. Family history, other medications, lifestyle factors, and pre-existing conditions are common defenses. Strong medical documentation helps overcome this challenge.
What to Expect During the Mass Tort Eligibility Screening Process
Once you contact an attorney, your claim goes through a formal screening process. Understanding this process is an important part of any mass tort eligibility guide. The screening typically takes two to four weeks.
Initial consultation. The attorney asks about your product use, medical history, and timeline. This is usually free. Most consultations last 15 to 30 minutes. The attorney determines whether your claim warrants further investigation.
Medical record review. If your case passes initial screening, the attorney requests your medical records. These records must confirm your diagnosis and treatment. The attorney’s medical team reviews them for consistency with known case criteria.
Case evaluation. The attorney assesses whether your claim meets all five core criteria. They evaluate the strength of your evidence. They determine which MDL or state court docket your case belongs in. They explain the likely timeline and process.
Retainer agreement. If the attorney accepts your case, you sign a retainer agreement. This spells out the contingency fee — typically 33% to 40% of any recovery. You pay nothing upfront. The attorney advances all litigation costs.
Not every case that passes screening will result in compensation. But the screening process ensures that only viable claims move forward. This protects both the plaintiff and the integrity of the litigation.
Frequently Asked Questions About Mass Tort Eligibility
How do I know if I qualify for a mass tort lawsuit?
You may qualify if you used a specific product and developed a diagnosed medical condition linked to it. This mass tort eligibility guide outlines five core criteria: product use, qualifying diagnosis, causation, sufficient exposure, and timely filing. An attorney can evaluate your situation at no cost during an initial consultation.
Is there a deadline to file a mass tort claim?
Yes. Every state has a statute of limitations for personal injury claims. These range from one to six years. Two to three years is most common. The discovery rule may extend your deadline. Check our statute of limitations guide for details.
Do I need a lawyer to join a mass tort?
You are not legally required to have an attorney. However, mass tort litigation is extremely complex. Most plaintiffs retain experienced mass tort lawyers. These attorneys typically work on contingency. You pay nothing upfront. They collect a percentage only if you receive compensation. Learn more in our guide on finding a mass tort lawyer.
What is the difference between a mass tort and a class action?
In a mass tort, each plaintiff files individually and must prove their own injury. In a class action, one representative sues for everyone. Mass tort eligibility requires more evidence. But it can result in higher individual payouts. Read our full mass tort vs. class action comparison for a detailed breakdown.
How long do mass tort cases take to resolve?
Mass tort cases typically take three to seven years from filing to resolution. Some last longer. The 3M earplug MDL took about four years from creation to final settlement. Roundup litigation has been ongoing since 2016. Camp Lejeune claims filed in 2022 are still being processed. Understanding the settlement process helps set realistic expectations.
Can I file if I live in a different state than the MDL court?
Yes. MDL consolidation is a procedural tool. Your claim is transferred to the MDL court for pretrial proceedings only. You can file regardless of where you live. However, your home state’s laws still apply. This includes statutes of limitations. State-specific rules are detailed in our 50-state comparison tool.
What compensation can I receive in a mass tort?
Compensation varies based on injury severity, medical expenses, lost wages, and pain and suffering. Recent mass tort settlements have ranged from a few thousand dollars to over $500,000 per claimant. No outcome is ever certain. Each case is evaluated individually based on its own facts and evidence.
Are there any upfront costs to file a mass tort claim?
Most mass tort attorneys work on a contingency fee basis. You pay no upfront costs. The attorney advances litigation expenses. If the case is successful, the attorney typically receives 33% to 40% of recovery. If there is no recovery, you owe nothing. Always confirm the fee arrangement in writing before signing a retainer.
