Paraquat Lawsuit Settlement
Calculator (2026)
Estimate a potential settlement range for a paraquat-related Parkinson's disease claim. No global paraquat settlement has been reached — the figures below are illustrative, pre-settlement estimates based on comparable finalized herbicide-MDL litigation, not confirmed paraquat-specific payouts.
Deadlines to file a paraquat lawsuit vary by state and generally range from 1 to 6 years from diagnosis or discovery of the link between exposure and Parkinson's disease. Missing your state's deadline can permanently bar your claim. Do not wait — consult a licensed attorney promptly to confirm the deadline that applies to you.

Paraquat MDL: Where the Litigation Stands
Paraquat lawsuits allege that long-term exposure to the herbicide paraquat dichloride is linked to an increased risk of developing Parkinson's disease, and that manufacturers failed to adequately warn users. As of the site's content-reviewed date, this litigation remains in the pretrial and discovery phase — no global settlement has been announced or finalized.
| MDL Detail | Status |
|---|---|
| Consolidation | Multidistrict Litigation (MDL No. 3004), In re: Paraquat Products Liability Litigation |
| Court | U.S. District Court, Southern District of Illinois |
| Presiding Judge | Judge Nancy Rosenstengel |
| Approximate pending claims | Roughly in the thousands, as of the most recent filings (case counts change constantly and should not be treated as precise) |
| Global settlement | Not yet reached — bellwether trials and pretrial proceedings are ongoing |
| Case type | Individual claims consolidated for pretrial purposes — this is an MDL, not a class action |
Litigation status changes frequently. This table reflects the general posture of the case as of the site's stated content-review date and should be verified with current court records or a licensed attorney before relying on it.
What "MDL" Means for Your Claim
Unlike a class action, an MDL consolidates individual lawsuits only for shared pretrial proceedings (discovery, expert testimony, bellwether trials). Each plaintiff's case is still evaluated and — if it resolves — settled or tried individually. That means your eventual outcome depends on your own case facts, not a single shared payout formula.
Factors That Affect a Paraquat Settlement Estimate
Because no global paraquat settlement exists yet, these factors are used by attorneys and legal analysts to build illustrative, comparable-litigation estimates rather than to quote confirmed payout figures.
1. Diagnosis Stage
The stage and severity of Parkinson's disease at diagnosis is typically the single largest driver of illustrative case value. Advanced Parkinson's disease, with significant motor and cognitive impact, generally correlates with higher estimated value than early-stage disease or general parkinsonism symptoms, largely because of higher projected future medical costs and greater loss of function and earning capacity.
2. Exposure Type & Role
Licensed agricultural applicators who directly mixed, loaded, or sprayed paraquat generally have the strongest and most direct exposure narrative. Farm workers and bystanders in treated fields, mixing/loading personnel, and residential or other exposure routes typically carry progressively lower — but still potentially viable — exposure profiles.
3. Years of Exposure
Longer documented exposure periods generally strengthen the causal link attorneys must establish between paraquat use and a Parkinson's diagnosis. Multi-year or multi-season exposure histories, especially in an agricultural occupation, tend to support stronger claims than brief or isolated exposure incidents.
4. Documentation Strength
Purchase receipts, employment records, pesticide-applicator licenses, farm logs, or co-worker affidavits that place you at a specific site using a specific paraquat product materially strengthen a claim. Strong documentation tends to support the higher end of any illustrative range; limited or entirely undocumented exposure claims are more difficult to value and may face a steeper evidentiary path.
5. Age at Diagnosis
Younger plaintiffs diagnosed with Parkinson's disease generally have more remaining work-life expectancy and a longer horizon of projected future medical costs and lost income, which can support a higher illustrative estimate. Older plaintiffs may have fewer economic damages but a shorter, more direct exposure-to-diagnosis timeline in some cases.
6. Litigation Timing & Venue
Because paraquat litigation is still consolidated in a single MDL without a global settlement, illustrative values may shift as bellwether trial outcomes, expert-testimony rulings, and settlement negotiations develop. Values discussed today are necessarily provisional and should be revisited with your attorney as the litigation progresses.
Statute of Limitations by State (General Ranges)
The figures below are general personal-injury / product-liability filing windows commonly cited for illustrative purposes. They are approximate, exceptions and "discovery rule" extensions often apply, and they are not legal advice. Confirm your exact deadline with a licensed attorney in your state.
| State | General Filing Window* |
|---|---|
| California | ~2 years from discovery |
| Texas | ~2 years from discovery |
| Florida | ~2–4 years from discovery |
| New York | ~3 years from discovery |
| Illinois | ~2 years from discovery |
| Pennsylvania | ~2 years from discovery |
| Ohio | ~2 years from discovery |
| Georgia | ~2 years from discovery |
| North Carolina | ~3 years from discovery |
| Michigan | ~3 years from discovery |
*General ranges only — approximate and simplified for illustration. Actual deadlines depend on your specific facts, the "discovery rule" in your state, and any applicable tolling provisions. This table is not legal advice.
Even where a discovery-rule extension may apply, gathering exposure evidence (purchase records, employment history, witness statements) becomes harder the longer you wait. If you or a family member has been diagnosed with Parkinson's disease after documented paraquat exposure, a prompt consultation with a licensed attorney helps preserve your options before any applicable deadline passes.
How Paraquat Compares to the Roundup (Glyphosate) Litigation
The paraquat MDL is frequently compared to the Roundup/glyphosate litigation because both involve allegations that a widely used agricultural herbicide caused serious disease (non-Hodgkin lymphoma for Roundup; Parkinson's disease for paraquat) and that the manufacturer failed to adequately warn users. The Roundup litigation is a useful reference point because it is one of the few herbicide mass torts that has actually reached large-scale settlements and trial verdicts — but it is a different chemical, different disease, and a legally distinct set of claims.
Why the Comparison Is Illustrative Only
Roundup litigation settlement and verdict patterns are sometimes used by attorneys as a rough analytical framework for estimating potential paraquat case values, since both are herbicide-manufacturer mass torts with comparable evidentiary structures (exposure history, product identification, disease-causation experts). However, paraquat litigation has not reached a global settlement, no bellwether verdicts have set a confirmed valuation benchmark at the time of this review, and Parkinson's disease claims involve different medical causation science than non-Hodgkin lymphoma claims. Any number derived from the Roundup comparison is an estimate for educational purposes — not a confirmed or guaranteed paraquat figure.

Paraquat Lawsuit Settlement FAQ
Answers to the most common questions about paraquat lawsuits, the MDL, and this calculator's estimates.
What is the average paraquat lawsuit settlement amount?
No global paraquat settlement has been reached, so there is no confirmed average payout yet. Attorneys and legal analysts publish illustrative pre-settlement estimates based on comparable herbicide-MDL outcomes (such as the Roundup/glyphosate litigation), generally ranging from roughly $75,000 for early Parkinson's disease claims to $920,000 or more for advanced cases with strong documented exposure. These figures are estimates only, not guarantees or confirmed case values.
Is there a paraquat class action lawsuit?
No. Paraquat claims are not a class action. They are consolidated as an MDL (Multidistrict Litigation) in the U.S. District Court for the Southern District of Illinois before Judge Nancy Rosenstengel for pretrial proceedings. In an MDL, each plaintiff keeps an individual claim and receives an individual settlement or verdict rather than a shared class payout.
How many paraquat lawsuits have been filed?
As of the most recent filings referenced by court dockets, approximately several thousand paraquat lawsuits are pending in the consolidated MDL. Case counts change frequently as new claims are filed and others resolve, so any specific number should be treated as an approximate snapshot rather than a precise current total.
What is the statute of limitations for a paraquat lawsuit?
The statute of limitations for paraquat claims varies by state, typically ranging from 1 to 6 years from diagnosis or from when you reasonably discovered the link between paraquat exposure and your Parkinson's disease (the "discovery rule"). Because deadlines vary significantly and can bar your claim permanently once they pass, you should consult a licensed attorney promptly to confirm the deadline that applies in your state.
How is a paraquat settlement value estimated before a global settlement exists?
Because paraquat litigation has not reached a global settlement, estimates are illustrative and drawn from patterns in comparable finalized herbicide mass-tort litigation (such as Roundup/glyphosate), adjusted for factors specific to paraquat cases: diagnosis stage (early PD, moderate PD, advanced PD, or parkinsonism/related symptoms), type and duration of exposure, age at diagnosis, and the strength of documentation such as purchase records or employment history showing exposure.
How much will I actually take home after attorney fees?
Most paraquat lawsuit attorneys work on contingency fees of roughly 33% to 40% of the gross settlement, plus case expenses (expert witnesses, medical record retrieval, filing fees) that are typically deducted as well. Net take-home to the plaintiff after fees and expenses is commonly estimated at around 55%–65% of the gross settlement amount, though this varies by firm and case.
