Wyoming uses modified comparative fault with 50% bar. Authority: Wyo. Stat. § 1-1-109.
The Wyoming pattern jury instructions ask jurors to determine: (1) was the defendant negligent? (2) was the plaintiff negligent? (3) was each party\'s negligence a substantial factor in causing the injury? (4) what percentage of fault, totaling 100%, do you assign to each party?
The court applies the modified comparative fault (50% bar) formula to those percentages after the verdict form is returned.
In any contested Wyoming injury case, fault is not a single yes-or-no. The jury allocates responsibility between the plaintiff and the defendant (and any third parties), and the state's comparative-fault rule then converts those percentages into the final dollar recovery.
Under Wyoming's modified-comparative rule, a 49%-at-fault plaintiff with a $1,000,000 verdict recovers $510,000. A 50%-at-fault plaintiff with the same verdict recovers $0. One percentage point converts to a million dollars.
Pre-trial settlement valuation and trial strategy in Wyoming both turn on these numbers. Below: five scenarios at common verdict sizes and fault percentages, with the recovery a Wyoming plaintiff would actually receive under the state\'s modified comparative fault (50% bar) rule.
| Verdict | Plaintiff fault | Net recovery | Reduction |
|---|---|---|---|
| $100,000 | 10% | $90,000 | $10,000 |
| $250,000 | 25% | $187,500 | $62,500 |
| $500,000 | 49% | $255,000 | $245,000 |
| $500,000 | 50% | $0 | $500,000 |
| $1,000,000 | 60% | $0 | $1,000,000 |
Scenario: a slip-and-fall plaintiff is awarded $1,000,000 by a Wyoming jury, with 10% of fault attributed to them for not watching where they walked. Under Wyoming law (modified comparative fault (50% bar)), the final award is $90,000.
Scenario: a slip-and-fall plaintiff is awarded $1,000,000 by a Wyoming jury, with 25% of fault attributed to them for not watching where they walked. Under Wyoming law (modified comparative fault (50% bar)), the final award is $187,500.
Scenario: a slip-and-fall plaintiff is awarded $1,000,000 by a Wyoming jury, with 49% of fault attributed to them for not watching where they walked. Under Wyoming law (modified comparative fault (50% bar)), the final award is $255,000.
Scenario: a slip-and-fall plaintiff is awarded $1,000,000 by a Wyoming jury, with 50% of fault attributed to them for not watching where they walked. Under Wyoming law (modified comparative fault (50% bar)), the final award is $0.
Practical illustration: an injured driver wins a $200,000 verdict in Wyoming and the jury assigns 60% fault to them. Applying Wyoming's modified comparative fault (50% bar) rule yields a net recovery of $0.
The settlement value of a Wyoming case depends not just on damages but on fault projection. Adjusters discount offers heavily when liability is contested and the rule allows a bar at some threshold. A plaintiff with a "75/25" liability case in a 50%-bar state settles differently than the same case in a pure-comparative state.
Voir dire and jury instructions in Wyoming comparative-fault cases shape outcomes as much as the underlying facts. Plaintiffs' counsel often spends opening arguments framing the plaintiff's actions as reasonable, knowing that even a moderate fault allocation can significantly reduce the verdict.
Wyoming comparative-negligence rules only matter if you file on time. The state\'s personal-injury statute of limitations is 4 years from the date of injury (Wyo. Stat. § 1-3-105). Even an airtight liability case is dismissed with prejudice if the complaint is filed late.
Wyoming applies modified comparative fault (50% bar). Wyoming uses modified comparative fault with 50% bar.
Wyoming bars recovery when the plaintiff is 50% or more at fault.
Wyoming jurors are presented with a special verdict form asking them to assign fault percentages totaling 100% to each party (and any non-party at fault under joint-tortfeasor rules). The trial court then applies the comparative-fault formula to compute the final recovery.
Yes. Wyoming juries can apportion fault among multiple defendants (and sometimes non-party tortfeasors). The treatment of joint and several liability , whether each defendant is liable only for their share or for the entire judgment if others are insolvent , varies by state statute.
Wyoming courts vary on the "seat-belt defense." Some states allow evidence of non-use as a fault factor; others (by statute or judicial rule) exclude it. Plaintiffs\' counsel should consult current Wyoming appellate decisions before deciding how to handle the issue at trial.
Generally yes , Wyoming\'s comparative-fault rule applies across negligence claims, including medical malpractice. Some states adjust the framework for medmal cases (e.g., reducing the plaintiff-fault relevance because patients rarely contribute to their own injuries in the traditional sense), but the basic rule applies unless the statute carves out an exception.
In modified comparative fault (50% bar) Wyoming, the bar threshold becomes the focal point of settlement: defendants negotiate harder near the threshold, plaintiffs accept reduced offers to avoid the bar.
