Ohio Rev. Code § 505.43
In order to obtain police protection, or to obtain additional police protection, any township may enter into a contract with one or more townships, municipal corporations, park districts created pursuant to section 511.18 or 1545.01 of the Revised Code, county sheriffs, joint police districts, or with a governmental entity of an adjoining state upon any terms that are agreed to by them, for services of police departments or use of police equipment, or the interchange of the service of police departments or use of police equipment within the several territories of the contracting subdivisions, if the contract is first authorized by respective boards of township trustees or other legislative bodies. The cost of the contract may be paid for from the township general fund or from funds received pursuant to the passage of a levy authorized pursuant to division (J) or (JJ) of section 5705.19 and section 5705.25 of the Revised Code.
Chapter 2744. of the Revised Code, insofar as it is applicable to the operation of police departments, applies to the contracting political subdivisions and police department members when the members are rendering service outside their own subdivision pursuant to the contract.
Police department members acting outside the subdivision in which they are employed may participate in any pension or indemnity fund established by their employer to the same extent as while acting within the employing subdivision, and are entitled to all the rights and benefits of Chapter 4123. of the Revised Code, to the same extent as while performing service within the subdivision.
The contract may provide for a fixed annual charge to be paid at the times agreed upon and stipulated in the contract.
