Political subdivisions are immune to any subrogation claim brought by an insurer.

UM/UIM Claims - R.C. § 3937.18 (E)

In the event of payment to an insured for an uninsured/underinsured motorist claim, the insurer making such payment is entitled to the proceeds of any settlement or judgment resulting from the exercise of the insured’s rights against a legally liable party. This right is limited by relevant insolvency proceedings.

If an insurance company pays to or on behalf of its insured any amount later determined to be due from another insurer, it shall be subrogated to all rights of the insured against such insurer.

Workers’ Compensation Subrogation Rights - R.C. § 4123.93

This statute became effective April 9, 2003 , and therefore applies only to injuries occurring on or after that date. It restores subrogation rights of the Ohio Bureau of Workers’ Compensation and self-insured employers. For claims where the injury occurred prior to April 9, 2003 , there is no right of subrogation.

Employees now must notify the lienholder if there is a third-party who is responsible for their injuries so that there is a reasonable opportunity to assert their subrogation rights. Responsible parties include UM/UIM insurers.

If an employee is not made whole, then the statute prescribes a formula for pro-rata distribution of any recovery between the employee and lienholder.

If there is the potential for future payments by the lienholder, a portion of the recovery is to be put in an interest bearing trust account to protect any future lien.
