In New Hampshire, accidents involving multiple at-fault parties are handled under the state’s modified comparative negligence law. This means that each party’s degree of fault is assessed, and compensation is adjusted accordingly. If you are found to be 50% or more at fault, you cannot recover damages. However, if you are less than 50% at fault, you can still receive compensation, but it will be reduced by your percentage of fault. It’s crucial to gather evidence and consult with a legal expert to navigate these complex cases effectively.
