(a) A contract, otherwise valid, of a type described in Kan. Stat. Ann. § 38-618, and amendments thereto, entered into during one’s minority, cannot be disaffirmed on that ground, either during the minority of the person entering into the contract or at any time thereafter, if the contract has been approved by the district court in any county in which the minor resides or is employed or in which any party to the contract has its principal office in this state for the transaction of business.

(b) Approval of the district court may be given upon petition of any party to the contract, after such reasonable notice to all other parties to the contract as is fixed by the district court, with opportunity for such other parties to appear and be heard.

(c) Approval of the district court given under this section extends to the whole of the contract and all of its terms and provisions, including, but not limited to, any optional or conditional provisions contained in the contract for extension, prolongation or termination of the term of the contract.

(d) For the purposes of any proceeding under this act, a parent or legal guardian entitled to the physical custody, care and control of the minor child at the time of the proceeding shall be considered the minor child’s guardian ad litem for the proceeding, unless the district court shall determine that appointment of a different individual as guardian ad litem is required in the best interests of the minor child.
