The petitioner or attorney for the petitioner, if a decree of adoption is entered, shall mail a certified copy of the decree to the former parent of the adult adoptee, if the parent has had no notice of the proceeding and, with reasonable diligence, can be located for service by first-class mail. The petitioner or the attorney shall file proof of mailing with the court or shall file an affidavit setting forth the reasons for noncompliance if the reasons are not evident from the verified pleadings on file.
