§ 383. Care and custody of children. 1. The parent of a child remanded or committed to an authorized agency shall not be entitled to the custody thereof, except upon consent of the court, public board, commission, or official responsible for the commitment of such child, or in pursuance of an order of a court or judicial officer of competent jurisdiction, determining that the interest of such child will be promoted thereby and that such parent is fit, competent and able to duly maintain, support and educate such child. The name of such child shall not be changed while in the custody of an authorized agency.

2. The custody of a child placed out or boarded out and not legally adopted or for whom legal guardianship has not been granted shall be vested during his minority, or until discharged by such authorized agency from its care and supervision, in the authorized agency placing out or boarding out such child and any such authorized agency may in its discretion remove such child from the home where placed or boarded.

3. Any adult husband and his adult wife and any adult unmarried person, who, as foster parent or parents, have cared for a child continuously for a period of twelve months or more, may apply to such authorized agency for the placement of said child with them for the purpose of adoption, and if said child is eligible for adoption, the agency shall give preference and first consideration to their application over all other applications for adoption placements. However, final determination of the propriety of said adoption of such foster child shall be within the sole discretion of the court, as otherwise provided herein.

Foster parents having had continuous care of a child, for more than twelve months, through an authorized agency, shall be permitted as a matter of right, as an interested party to intervene in any proceeding involving the custody of the child. Such intervention may be made anonymously or in the true name of said foster parents.

4. An adult married person who has executed a legally enforceable separation agreement or is a party to a marriage in which a valid decree of separation has been entered and who becomes or has been the custodian of a child placed in their care as a result of court ordered foster care may apply to such authorized agency for placement of said child with them for the purpose of adoption. Applications filed pursuant to this subdivision by persons who, as foster parents, have cared for a child continuously for a period of twelve months or more shall be entitled to the same consideration and preference as are given to applications filed pursuant to subdivision three of this section. Final determination of the propriety of said adoption of such foster child, however, shall be within the sole discretion of the court, as otherwise provided herein.

5. Any proceeding brought in connection with the provisions of this section shall have preference over all other causes in all courts.
