Ohio Rev. Code § 5310.12
As used in this section, "incompetent person" means a person who is so mentally impaired, as a result of a mental or physical illness or disability, as a result of an intellectual disability, or as a result of chronic substance abuse, that the person is incapable of taking proper care of the person's self or property or fails to provide for the person's family or other persons for whom the person is charged by law to provide.
No action or proceeding for compensation from the assurance fund provided for in section 5310.05 of the Revised Code for, or by reason of, any deprivation, loss, or damage shall be made, brought or taken, except within a period of six years from the time when the right to bring such action or proceeding first accrued. If at the time when such right of action first accrues the person entitled to bring such action or take such proceedings is within the age of eighteen years, an incompetent person, imprisoned, or absent from the United States in the service of the United States or of this state, such person or anyone claiming from, by, or under the person, may bring the action at any time within two years after such disability is removed.
