Personal Injury Laws in Ohio: Deadlines, Fault Rules & Damages

In Ohio, you generally have two years from the date of injury to file a personal-injury lawsuit for negligence — car crashes, slip-and-falls, dog bites, and most other injury claims. This comes from Ohio Revised Code §2305.10(A). Miss that window and, with a few narrow exceptions, an Ohio court will dismiss your case no matter how strong it is. Claims against a city, county, or the state itself can require formal notice much sooner, so don't wait to sort out who is responsible.

This guide explains Ohio's specific rules on deadlines, shared fault, damage limits, car insurance, and dog bites — with citations to the Ohio Revised Code so you can read the actual law yourself. It is general information, not legal advice, and Ohio's statutes are amended periodically, so always confirm the current text at codes.ohio.gov or with an Ohio court before relying on any deadline.

1. Ohio's Personal Injury Statute of Limitations

Ohio Revised Code §2305.10(A) sets a two-year limit for "an action for bodily injury or injuring personal property," measured from the date the injury occurred (when the "cause of action accrues"). This two-year clock applies to most everyday injury claims: car and truck accidents, slip-and-falls, dog bites, and product-related injuries.

• Medical malpractice has its own one-year statute under Ohio Revised Code §2305.113, generally running from the date of the negligent act or its discovery, with a separate outer "statute of repose."
• Toxic or chemical exposure claims under §2305.10(B) can accrue later — when a doctor or "competent medical authority" informs you of the injury and its cause, or when you reasonably should have known, whichever is first.
• If the person responsible is out of state, hiding, or imprisoned, Ohio Revised Code §2305.15 can pause ("toll") the clock until they're found or released.
• Claims against a government entity almost always carry a shorter effective deadline because of notice and procedural rules — see the government-claims section below.

Because exceptions and tolling rules are fact-specific, confirm the deadline that applies to your situation against the current text of the Ohio Revised Code rather than assuming two years automatically applies.

2. Shared Fault: Ohio's 51% Bar Rule

Ohio uses modified comparative negligence with a 51% bar, codified at Ohio Revised Code §2315.33. In plain terms:

• If you were 50% or less at fault, you can still recover damages, but the award is reduced by your percentage of fault. Example: $100,000 in damages, found 20% at fault, you collect $80,000.
• If you were 51% or more at fault, Ohio law bars you from recovering anything from the other party.

Insurance adjusters routinely push to assign injured claimants extra fault specifically because crossing that 51% line eliminates the entire claim. Get any fault percentage the insurer proposes in writing, and don't accept a fault assignment before you've reviewed the accident report, photos, and any witness statements.

3. Damage Caps in Ohio

Ohio does not cap economic damages (medical bills, lost wages, future income loss) in any personal injury case. It does limit certain non-economic and punitive awards:

• Non-economic damages, general tort cases (Ohio Revised Code §2315.18): capped at the greater of $250,000 or three times economic damages, up to $350,000 per plaintiff (or $500,000 per occurrence for multiple plaintiffs). The cap does not apply to cases involving permanent and substantial physical deformity, loss of a bodily organ system, or a permanent injury that prevents the person from being able to independently care for themselves and perform life-sustaining activities.
• Medical malpractice non-economic damages (Ohio Revised Code §2323.43): a similar $250,000/3x formula, capped at $350,000 per plaintiff or $500,000 per occurrence — rising to a $500,000 (or $1 million per occurrence) ceiling for the same catastrophic-injury categories.
• Punitive damages (Ohio Revised Code §2315.21): generally capped at twice the compensatory damages awarded; for an individual or "small employer" defendant, the cap is the lesser of twice compensatory damages or 10% of that defendant's net worth, up to $350,000. Punitive damages require proof of malice or egregious/fraudulent conduct, not ordinary negligence.

Important caveat: Ohio's medical-malpractice non-economic cap has been challenged in court. In Paganini v. Cataract Eye Center of Cleveland (8th Dist. Ct. App., 2025), an Ohio appeals court held the cap unconstitutional as applied to a patient who permanently lost an eye, allowing an award well above the statutory ceiling; that decision is now under review by the Supreme Court of Ohio. The ruling does not repeal the cap statewide — the Supreme Court of Ohio has previously upheld Ohio's damage caps against constitutional challenge (facially in Arbino v. Johnson & Johnson, 2007, and as applied in Simpkins v. Grace Brethren Church of Delaware, 2016) — but it shows the cap's application to severe/"catastrophic" injuries is an unsettled, actively litigated area. Confirm the cap's current enforceability for your type of injury and county with a current review of Ohio case law.

4. Car Insurance: Ohio Is an At-Fault (Tort) State

Ohio is a traditional at-fault/tort state, not a no-fault state — there is no mandatory personal injury protection (PIP) requirement. The driver who caused the crash (and their liability insurer) is responsible for the other party's injury and property damage.

• Minimum liability limits are 25/50/25: $25,000 bodily injury per person, $50,000 per accident, $25,000 property damage.
• Insurers must offer uninsured/underinsured motorist (UM/UIM) coverage; you can reject it only in writing. Given how many drivers carry only the state minimum, UM/UIM coverage is worth keeping.
• You can pursue the at-fault driver's insurer directly, or, depending on your own policy, look to your own UM/UIM coverage if the other driver is uninsured or underinsured.

For current requirements or to check whether a driver is insured, the Ohio Department of Insurance is the state regulator to consult.

5. Dog Bites: Ohio Is a Strict Liability State

Ohio Revised Code §955.28 makes the owner, keeper, or harborer of a dog liable for injuries the dog causes — you generally do not have to prove the owner knew the dog was dangerous ("one bite" is not the rule in Ohio). This is closer to strict liability than most states that still use a one-bite standard.

• Liability can extend beyond the legal owner to a "keeper" (someone with custody/control of the dog) or "harborer" (someone who shelters the dog or allows it to live on their property), though Ohio courts continue to refine who qualifies — a 2026 Supreme Court of Ohio decision narrowed "harborer" status, holding that a residential property owner who merely allows tenants to keep dogs is not, by itself, a harborer of a tenant's dog.
• Statutory exceptions bar recovery if you were trespassing or committing a crime on the owner's property, committing a crime against a person, or teasing/tormenting/abusing the dog at the time of the bite.
• The general two-year personal injury deadline under §2305.10 applies to dog-bite claims.

Claims Against the Government: Shorter, Stricter Deadlines

If your injury involves a government entity — a city bus, a pothole on a state highway, a fall at a public building, a county employee's vehicle — different rules and much tighter practical timelines can apply:

• The State of Ohio: Claims go to the Ohio Court of Claims, not a regular county court. Ohio Revised Code §2743.16 sets a two-year filing deadline (or any shorter deadline that would apply between private parties), but the process also requires the claim to first go through the state's Office of Risk Management for possible settlement — start this immediately rather than waiting.
• Cities, counties, townships, and other political subdivisions: Governed by Ohio Revised Code Chapter 2744 (the Political Subdivision Tort Liability Act), which grants broad immunity except in specific carved-out situations (e.g., negligent operation of a motor vehicle by an employee). Even when a claim is allowed, it generally still must be filed within two years, and some subdivisions require earlier notice under their own charters or insurance procedures.
• Because government immunity exceptions are narrow and technical, and notice requirements vary by entity, don't assume you have the full two years to act — confirm the specific notice and filing rules for the exact city, county, or state agency involved as soon as possible after the injury.

Where to File: Ohio's Courts

Most personal injury lawsuits in Ohio are filed in the Court of Common Pleas for the county where the injury happened or where the defendant lives/does business; smaller claims may go to a county or municipal court. Claims against the State of Ohio go to the Ohio Court of Claims in Columbus. The Supreme Court of Ohio's website links to every county's court system if you need to identify the right venue.

What to Do in Ohio After an Injury

1. Get medical care and document everything. Prompt treatment protects your health and creates the medical record that proves both the injury and when it happened.
2. Identify who's involved before you talk fault. Note whether a government vehicle, employee, or property was involved — this changes your deadline and process dramatically.
3. Preserve evidence fast. Photos of the scene, the accident report, witness names, and the other driver's or dog owner's insurance information.
4. Report government-related injuries immediately. If a state, city, or county entity may be responsible, don't wait — contact the relevant office (or the state's Office of Risk Management) right away given the shorter practical windows involved.
5. Be careful with fault statements. Given Ohio's 51% bar, avoid signing any insurer document assigning you a fault percentage before you've reviewed the facts.
6. Track every calendar date. Mark the two-year mark from your injury date, and note any shorter deadline that might apply (medical malpractice, government claims).
7. Confirm current law before you rely on it. Statutes and case law — especially damage caps — are actively being litigated in Ohio; check codes.ohio.gov or with an Ohio court for the current text before you make decisions based on a specific number or deadline.
