In short
- An Ohio claims rule says an insurer must document how it applied comparative negligence to a claim settlement.
- The rule says the insurer must fully disclose that information to the claimant on the claimant's written request.
- In court, Ohio law lowers damages by the plaintiff's share of fault, and fault that is greater than the others' combined bars recovery.
What this means
This answer uses Ohio sources only. Under Ohio Administrative Code rule 3901-1-54, which defines "claimant" to include a third party claimant (see our Ohio answer on response times), an insurer must document the application of comparative negligence to any claim settlement. The rule says the insurer must fully disclose that information to the claimant upon the claimant's written request. In a court case, Ohio Revised Code 2315.33 says contributory fault does not bar a plaintiff from recovering damages if the plaintiff's fault was not greater than the combined tortious conduct of all others, and that the court diminishes the damages by the plaintiff's percentage. The sources do not say what percentage would be given in your crash, and they do not say how an insurer decides fault before any court case.
Your next step
Send a written request to the other insurer asking for its comparative negligence documentation. Keep the police report and photos. The Ohio rule gives fifteen days to respond to a communication (see our Ohio answer on response times).

Open the Ohio rule and read section (G)(9). Open Ohio Revised Code 2315.33.
