If the person who is adopted in an adult adoption was born in a state which requires a court order prior to issuing a new birth certificate, upon petition of the parent, parents, or the person adopted, a court of proper jurisdiction may grant a judgment recognizing the adoption based upon the authentic act of adoption without further proceedings. In this case, the validity and civil effects of the authentic act of adoption are not affected by the court order and shall continue to be governed by the applicable laws.
