Ohio Rev. Code § 3125.13
Each child support enforcement agency may enter into contracts with public agencies and private vendors for assistance in establishing paternity or support obligations, or for the performance of other administrative duties of the agency. Each child support enforcement agency may contract with a collection agent for the collection of arrearages owed under child support orders being administered by the agency. If the department of job and family services or a child support enforcement agency contracts with a collection agent for the collection of arrearages, the collection agent is not required to be licensed as a private investigator under Chapter 4749. of the Revised Code. Before entering into a contract for assistance in establishing paternity or support obligations, for other administrative services, or for the collection of arrearages by a collection agent, a child support enforcement agency shall comply with sections 307.86 to 307.92 of the Revised Code and any rules adopted by the director of job and family services pursuant to section 3125.25 of the Revised Code.
