IN RE A.W.

A mother and an unknown father were the subjects of a petition to terminate parental rights and to adopt a child.  Only mother appeals.  She argues that she lacked notice of the proceedings and that the petitioners failed to comply with the parental termination statutes.  She also contests the statutory grounds relied on for terminating her parental rights and the trial court’s determination that termination was in her child’s best interest.  We affirm the termination of the mother’s parental rights.  But because the record does not reflect that the unknown father was served under the Tennessee Rules of Civil Procedure or the statutes governing substituted service, we vacate the judgment terminating his parental rights.
