If you were hurt in Ohio by someone else's conduct, you generally have two years from the date of the injury to file a personal-injury lawsuit. The deadline comes from Ohio Revised Code section 2305.10, and the clock starts on the date the harm occurred. Miss the window and the courthouse door closes.
The two-year number is the rule most Ohio injury searches return. The single biggest trap in Ohio PI practice is the one-year SOL for medical malpractice under ORC section 2305.113, one of the shortest medmal windows in the country. The other exceptions are a two-year SOL for political-subdivision claims under ORC section 2744.04, the 180-day-letter option that can extend the medmal SOL, and a 51% modified-comparative-fault bar. This post walks each one, plus the fact patterns we see trip Ohio claimants up most.
The default Ohio PI window: two years under ORC 2305.10
Ohio Revised Code section 2305.10 sets a two-year statute of limitations for an action for bodily injury or injuring personal property. It is the catch-all for the vast majority of Ohio PI cases: car crashes, slip-and-falls, dog bites, premises liability, and most negligence claims.
The clock starts on the date the injury occurred. Ohio recognizes a discovery rule in narrow categories where the injury was not reasonably knowable at the time it occurred.
Ohio is a fault-based auto-insurance state. The injured party's recovery generally runs through the at-fault driver's insurer or your own uninsured-motorist coverage.
The 1-year medmal SOL: shortest in the country
Medical-malpractice cases in Ohio run under ORC section 2305.113(A): a one-year SOL from the act or omission, or from the termination of the physician-patient relationship for that condition, whichever is later. One year. Not two. This is the shortest medmal window in the country and the single largest trap in Ohio medical-injury practice.
ORC section 2305.113(B)(1) provides a 180-day-letter option: a claimant who delivers written notice of a potential claim to a defendant within the one-year SOL extends the SOL by 180 days. The letter must comply with the statutory requirements (specific defendant identification, claim description). Many Ohio medmal claims are saved by a timely 180-day letter.
ORC section 2305.113(C) sets a four-year statute of repose: no medmal claim may be commenced more than four years after the act or omission, regardless of discovery, with limited tolling for fraudulent concealment, minors, and unsound mind.
Exception two: political-subdivision and State claims
Claims against political subdivisions (cities, counties, townships) run under ORC section 2744.04(A): a two-year SOL with no general pre-suit notice requirement. The Political Subdivision Tort Liability Act (ORC chapter 2744) preserves immunity in most cases, with narrow exceptions under ORC section 2744.02(B): motor-vehicle operation, negligent road maintenance, certain proprietary functions, defects in public buildings, and others.
Claims against the State of Ohio are filed in the Court of Claims under ORC chapter 2743 with a two-year SOL.
Exception three: minors
ORC section 2305.16 tolls the general PI SOL during minority. A child injured at age 10 has until age 20 to file under ORC section 2305.10. For medmal, the four-year repose typically extends to age 19 for minors under section 2305.113(C)(2), but the one-year SOL still requires action shortly after the conduct unless discovery applies. Minor tolling is narrower in medmal than in general PI.
What Ohio's modified 51% comparative-fault rule means
Ohio follows a modified comparative-fault rule with a 51% bar under ORC section 2315.33. A plaintiff 50% or less at fault recovers, reduced by the percentage of plaintiff fault. A plaintiff 51% or more at fault recovers nothing.
The 51% threshold is where Ohio defense lawyers focus. Push fault from 49% to 51% and the recovery flips from partial to zero.
A common Ohio fact pattern that ends cases early
The single most common Ohio medmal trap: a patient is harmed by a surgical mistake, focuses on recovery, returns to the doctor for several months of follow-up, then consults an attorney after the relationship sours, more than a year after the surgery. The one-year SOL has run. The case ends.
The mitigation: an attorney consulted within the one-year window can send a 180-day letter to extend the SOL. The letter is cheap and reversible; failing to send it before the clock runs is fatal.
If any medical injury is suspected, treat the one-year window from the act or from the end of the physician-patient relationship for that condition as the operative deadline.
Other Ohio-specific PI rules worth knowing
Dog bites. Strict liability under ORC section 955.28(B): the owner, keeper, or harborer of a dog is liable for any injury, death, or loss caused by the dog unless the injured person was trespassing, committing another criminal offense, or teasing, tormenting, or abusing the dog. Two-year SOL under ORC 2305.10. Ohio also allows common-law negligence claims with a one-bite-style requirement; statutory and common-law theories can be pleaded together.
Wrongful death. Two-year SOL under ORC section 2125.02(D)(1).
Slip-falls and open-and-obvious. Ohio historically applied the open-and-obvious doctrine as a complete bar to slip-fall liability. Recent decisions, including Kimmel v. Lin (2024), have narrowed the doctrine and clarified that obvious hazards are typically a comparative-fault question rather than a per se bar in many fact patterns. The doctrinal posture is evolving; recent case law matters.
How the LawSensai Personal Injury Recovery Center helps with Ohio matters
We built the Recovery Center to handle the day-one organizational work in an Ohio PI case so that nothing falls through the cracks during the two-year window, or the one-year medmal window when a medical injury is involved. We document the incident through a calm, save-and-resume intake, build a medical-and-evidence timeline, and surface every applicable deadline, including the one-year medmal SOL, the 180-day-letter option, the four-year medmal repose, the two-year political-subdivision SOL, and the underlying ORC 2305.10 two-year window. When the matter is well-documented and ready, we route it to a verified personal-injury attorney licensed in Ohio. Start your Ohio intake here.
