A proceeding under Family Code Section 7800 et seq. may be brought if the child has been left in any of following circumstances:
1) Without provision for identification by his or her parent or parents; or
2) By both parents or by his or her sole parent in the care and custody of another person without any provision for support or without communication from the parent or parents for six months; or
3) By one parent in the care and custody of the other parent without any provision for support or without communication from the absent parent for a period of one year.
All of my cases were brought under the factual situation described in option three. There are, unfortunately, many parents who leave their child or children in the custody of the other parent and fall off the face of the earth for periods over one year and fail to provide support or communicate with their child. Under the law this is abandonment and your parental rights can be terminated.
