Ohio Statute of Repose: Medical, Product, and Construction Deadlines

The Ohio statute of repose is a hard filing deadline that permanently bars certain civil claims after a fixed number of years measured from the defendant’s act, not from when you discovered the harm. Four periods do most of the work: four years for medical malpractice, four years for legal malpractice, ten years for product liability, and ten years for construction and design defects. Each has its own exceptions, and each can expire before you even know you were injured.

How Repose Differs From a Statute of Limitations

A statute of limitations starts when you know or should know you were harmed. A statute of repose ignores discovery and counts forward from the defendant’s act: the surgery, the product delivery, the substantial completion of a building, or the attorney’s error. Once the repose period runs, the claim is gone.

That means you can still have time on your statute of limitations and be blocked anyway. When both deadlines apply, the one that expires first controls.

Four-Year Repose for Medical Claims

Under Ohio Revised Code 2305.113(C), no medical malpractice action can be filed more than four years after the act or omission that forms the basis of the claim.¹ The clock runs from the date of the alleged error, not the date you noticed something was wrong. The period covers claims against physicians, dentists, optometrists, chiropractors, nurses, and hospitals, and it reaches errors in procedures, diagnosis, and follow-up care.

Late Discovery Within the Repose Period

If you could not have discovered the injury within three years despite reasonable diligence, but you do discover it before the four-year deadline, you get one additional year from the date of discovery to file suit.¹ The plaintiff carries the burden of proving by clear and convincing evidence that earlier discovery was not possible.

Foreign Objects Left in the Body

When a provider leaves an object such as a surgical sponge or a broken instrument tip inside a patient, you have one year from the date you discovered it or should have discovered it, even if the four-year repose period has already expired.¹

Minors and Persons of Unsound Mind

The four-year repose does not run against someone who was a minor or of unsound mind when the cause of action arose. Under Ohio Revised Code 2305.16, that person may file after the disability is removed, meaning after turning 18 or regaining legal capacity.²

Ten-Year Repose for Product Liability Claims

Ohio Revised Code 2305.10(C)(1) bars product liability claims filed more than ten years after the product was delivered to its first end-user purchaser or lessee.³ Buyers who acquired the product as a component to build into another product don’t count. The clock starts at the first consumer-level sale or lease.

Several exceptions can keep a product claim alive past the ten-year mark:

Manufacturer or supplier fraud about information regarding the product, where that fraud contributed to the harm.³
An unexpired express written warranty covering product safety for longer than ten years.³
A two-year tail: if the cause of action accrues in the last two years of the ten-year window, you get two years from accrual to file.³
Disability tolling for minors and persons of unsound mind: two years after the disability is removed.³
Asbestos exposure claims are exempt from the ten-year bar entirely. The cause of action accrues when a medical professional tells you the injury is asbestos-related, or when you reasonably should have known.³
Bodily injuries caused by exposure to certain hazardous substances or devices during the ten-year period follow a similar discovery-based accrual rule, with two years from the date you learn of the connection.³

Ten-Year Repose for Construction and Design Claims

Ohio Revised Code 2305.131 imposes a ten-year statute of repose on claims arising from defective conditions in improvements to real property, and it reaches anyone who designed, planned, supervised, or built the improvement. The clock starts at substantial completion, defined as the earlier of two dates: when the owner or tenant first uses the improvement for its intended purpose, or when the property becomes available for use after the work is finished per the contract.⁴ After ten years, claims for bodily injury, property damage, or wrongful death tied to the construction defect are barred.

Exceptions:

A two-year tail for discovery of a defective and unsafe condition during the last two years of the ten-year window; you have two years from discovery to file.⁴
Disability tolling for minors and persons of unsound mind whose claims accrued during the ten-year period: two years after the disability is removed.⁴
Fraud in the design, planning, supervision, or construction, or fraud regarding a relevant fact about the alleged defect, strips the defendant of the repose defense.⁴
An unexpired written warranty or guarantee lasting longer than ten years keeps the claim alive.⁴

Four-Year Repose for Legal Malpractice

Legal malpractice claims run under two overlapping deadlines. Ohio Revised Code 2305.11(A) sets a one-year statute of limitations that starts when you knew or should have known about the attorney’s error.⁵ Behind it sits a four-year statute of repose under Ohio Revised Code 2305.117(B), which bars any legal malpractice claim filed more than four years after the act or omission itself.⁶

The interaction matters. If an attorney drafts a flawed contract in 2022 and you spot the error in 2027, your one-year limitations clock has just started, but the four-year repose already expired in 2026. The claim is dead. Section 2305.117 carries the same tolling for minors and persons of unsound mind found in the other repose statutes, and its divisions (C) and (D) contain further provisions that can affect the deadline in specific circumstances.⁶

Pin Down the Triggering Date First

The single fact that decides whether a claim survives is the date the repose clock started. For medical malpractice, that’s the date of the alleged act or omission. For product liability, it’s the date the product was delivered to its first end-user purchaser or lessee. For construction and design, it’s the date of substantial completion as the statute defines it. For legal malpractice, it’s the date of the attorney’s act or omission.

Work backward from that date before anything else. If the repose period has run and no exception fits your facts, the merits of the claim will not save it. If the period is still open, or an exception plausibly applies, the shorter statute of limitations becomes the next deadline to check.
