1. (1) On receipt of a complaint filed under division (B)(2) of this section, the court shall schedule a hearing to determine, in accordance with Chapters 3119., 3121., 3123., and 3125. of the Revised Code, the amount of child support the minors' parents are required to pay, the method of paying the support, and the method of providing for the child's health care needs. On receipt of a request under division (B)(2) of this section, the agency shall schedule a hearing to determine, in accordance with Chapters 3119., 3121., 3123., and 3125. of the Revised Code, the amount of child support the minors' parents are required to pay, the method of paying the support, and the method of providing for the child's health care needs. At the conclusion of the hearing, the court or agency shall issue an order requiring the payment of support of the child and provision for the child's health care needs. The court or agency shall calculate the child support amount using the income of the minors' parents instead of the income of the minors. If any of the minors' parents are divorced, the court or agency shall calculate the child support as if they were married, and issue a child support order requiring the parents to pay a portion of any support imposed as a separate obligation. If a child support order issued pursuant to section 2151.23, 2151.231, 2151.232, 3111.13, or 3111.81 of the Revised Code requires one of the minors to pay support for the child, the amount the minor is required to pay shall be deducted from any amount that minor's parents are required to pay pursuant to an order issued under this section. The hearing shall be held not later than sixty days after the day the complaint is filed or the request is made nor earlier than thirty days after the court or agency gives the minors' parents notice of the action.
2. (2) An order issued by an agency for the payment of child support shall include a notice stating all of the following: that the parents of the minors may object to the order by filing a complaint pursuant to division (B)(2) of this section with the court requesting that the court issue an order requiring the minors' parents to pay support for the child and provide for the child's health care needs; that the complaint may be filed no later than thirty days after the date of the issuance of the agency's order; and that, if none of the parents of the minors file a complaint pursuant to division (B)(2) of this section, the agency's order is final and enforceable by a court and may be modified and enforced only in accordance with Chapters 3119., 3121., 3123., and 3125. of the Revised Code.
(D) An order issued by a court or agency under this section shall remain in effect, except as modified pursuant to Chapters 3119., 3121., 3123., and 3125. of the Revised Code until the occurrence of any of the following:
1. (1) The minor who resides with the parents required to pay support under this section reaches the age of eighteen years, dies, marries, enlists in the armed services, is deported, gains legal or physical custody of the child, or is otherwise emancipated.
