The two-year category in § 12-542
A.R.S. § 12-542 states that listed actions, including injuries done to another person, must be commenced and prosecuted within two years after accrual. The section includes separate language for injury when death ensues, while other claims and defendants can be governed elsewhere.
Arizona’s comparative-negligence text
Section 12-2505 says a claimant’s action is not barred when the jury applies contributory negligence or assumption of risk; damages are reduced in proportion to relative fault. The same section denies that comparative-negligence right to a claimant who intentionally, wilfully, or wantonly caused or contributed to the injury or death.
Allocation can include nonparties
Section 12-2506 generally makes each defendant liable for the amount allocated to that defendant and describes when nonparty fault may be considered. That makes early identification of people and entities connected to the event practically important.
