The general rule: two years, under ORC 2305.10
Under ORC § 2305.10(A), most lawsuits based on bodily injury, product liability, or damaged personal property must be filed within two years of accrual. Wrongful death claims carry the same two-year period, under ORC § 2125.02.
Two notable carve-outs: half the general time
Both assault and battery claims, and medical malpractice claims, get only one year — half the general rule. See our full guide to Ohio's discovery rule and tolling for exactly how these shorter periods work, along with a genuinely significant pending change for sexual assault survivors.
Minors and legal disability
Ohio tolls the clock for an injured minor until they turn 18, at which point the full relevant period begins running — so a child injured at age 10 generally has until age 20. A similar tolling rule applies when a legally disabled person suffers an injury.
Government vehicle accidents: a short notice requirement
If the at-fault vehicle was a government vehicle, additional steps and shorter deadlines can apply. See our full guide to Ohio government claim deadlines.
