Ohio Rev. Code § 3121.14
When a court has issued a court support order or a child support enforcement agency has issued an administrative child support order, when the issuing court or agency, or the agency administering the support order, has issued one or more notices containing one or more of the requirements described in section 3121.03 of the Revised Code or when a court or agency that issued the support order has issued one or more orders described in division (C) or (D) of that section, and when either the child support enforcement agency administering the support order receives a notification that pertains to a change in the source of income or status of accounts in a financial institution of the obligor or the agency administering the support order otherwise determines that the source of income or status of accounts in a financial institution of the obligor has changed, the agency administering the support order immediately shall conduct an investigation to determine the obligor's present source of income or assets, and the obligor's address and social security number and shall issue one or more notices described in section 3121.03 of the Revised Code that it determines are appropriate. If the agency determines that no notice of the type described in that section would be appropriate, the agency, with respect to a court support order, may request the court to issue a court order under division (C) or (D) of that section, and the agency may issue, with respect to an administrative child support order, an administrative order under division (D) of that section. On receipt of the request, the court, with respect to a court support order, may issue an order as described in division (C) or (D) of section 3121.03 of the Revised Code, and the agency, with respect to an administrative child support order, may issue an administrative order under division (D) of section 3121.03 of the Revised Code. The notices and court orders are final and are enforceable by the court. The notices shall be mailed within fifteen days after the obligor under the support order is located or within fifteen days after the default under the support order, whichever is applicable.
If the court or agency that issued the support order, or the agency administering the support order, previously has issued one or more notices containing one or more of the requirements described in section 3121.03 of the Revised Code, the court previously has issued one or more court orders described in division (C) or (D) of that section, or the agency has previously issued an order described under division (D) of that section and the agency administering the support order determines that any of the requirements or orders no longer are appropriate due to the change, the agency administering the support order immediately shall cancel any previously issued notice and cancel any previously issued administrative order under division (D) of section 3121.03 of the Revised Code that is no longer appropriate, and the court shall cancel any previously issued court order under division (C) or (D) of section 3121.03 of the Revised Code that no longer is appropriate, the agency shall send written notice of the cancellation by regular mail to the person who was required to comply with the withholding, deduction, or other requirement contained in the canceled notice or order, and the agency shall issue one or more new notices containing one or more requirements described in section 3121.03 of the Revised Code that it determines are appropriate. If the agency determines that no notice of the type described in that section would be appropriate, the agency, with respect to a court support order, may request the court to issue a court order under division (C) or (D) of that section, and the agency may issue, with respect to an administrative child support order, an administrative order under division (D) of that section. On receipt of the request, the court may issue an order as described in division (C) or (D) of section 3121.03 of the Revised Code, and the agency, with respect to an administrative child support order, may issue an administrative order under division (D) of section 3121.03 of the Revised Code. The notices and court orders are final and are enforceable by the court. The notices shall be mailed within fifteen days after the obligor under the support order is located or within fifteen days after the default under the support order, whichever is applicable.
