(1) Any person who is eighteen (18) years of age and who is a resident of this state or who has resided in this state for twelve (12) months next before filing may file a petition for leave to adopt a child in the Circuit Court of the county in which the petitioner resides.
(2) If the petitioner is married, the husband or wife shall join in a petition for leave to adopt a child unless the petitioner is married to a biological parent of the child to be adopted, except that if the court finds the requirement of a joint petition would serve to deny the child a suitable home, the requirement may be waived.

In all other adoptions, the petition shall not be filed until the child has resided continuously in the home of the petitioner for at least ninety (90) days immediately prior to the filing of the adoption petition.
(4) No petition for adoption shall be filed unless prior to the filing of the petition the child sought to be adopted has been placed for adoption by a child-placing institution or agency, or by the cabinet, or the child has been placed with written approval of the secretary; but no approval shall be necessary in the case of:
(a) A child sought to be adopted by a blood relative, including a relative of half- blood, first cousin, aunt, uncle, nephew, niece, and a person of a preceding generation as denoted by prefixes of grand, great, or great-great; stepparent; stepsibling; or fictive kin; however, the court in its discretion may order a report in accordance with KRS 199.510 and a background check as provided in KRS 199.473(8);
