The negligence standard
Wyoming applies modified comparative fault (51% bar): a plaintiff recovers, reduced by their share of fault, as long as their fault isn't greater than the defendants'.

Sample matter
Example: "A Jackson hiking guide's client was injured by falling rock on a trail the guide company had been told was unstable." Begin with Wyoming appellate decisions on similar facts, then confirm the governing law - Wyo. Stat. § 1-1-109 on comparative fault and Wyoming's Recreation Safety Act - and each case's later treatment.
LegiMatch is built for the first step: describe the matter and get up to 100 similar decisions, ranked by a match score you can inspect, each linked to the court's own text. It's a research tool, not legal advice.
