Ohio Rev. Code § 2117.37
If a claim is contingent at the time of a decedent's death and a cause of action subsequently accrues on the claim, it shall be presented to the executor or administrator, in the same manner as other claims, before the expiration of six months after the date of death of the decedent, or before the expiration of two months after the cause of action accrues, whichever is later, except as provided in section 2117.39 of the Revised Code. The executor or administrator shall allow or reject the claim in the same manner as other claims are allowed or rejected. If the claim is allowed, the executor or administrator shall proceed to pay it. If the claim is rejected, the claimant shall commence an action on the claim within two months after the rejection or be forever barred from maintaining an action on the claim.
