Upon the request of a surrogate and not more than 30 days prior to the hearing, the court shall conduct a search of the records of the central registry established pursuant to section 1 of P.L. 1999, c. 421(C.2C:25-34) to determine whether a prospective adoptive parent or any member of the parent's household has:
The court shall provide the results of the search to the surrogate for inclusion in the court's adoption file. If the results of the search contain any material findings or recommendations adverse to the plaintiff, the surrogate shall provide the material findings or recommendations to the approved agency.
If the agency's report contains or the results of the court's search of the central registry contain any material findings or recommendations adverse to the plaintiff, the agency shall serve a copy of that part of the agency's report or the results of the court's search upon the plaintiff at least five days prior to the hearing and the court shall appoint a guardian ad litem for the child in the adoption proceeding if the court determines that a guardian is necessary to represent the best interests of the child. If the approved agency that placed the child with the plaintiff has not consented to the adoption, the court may appoint another approved agency to conduct an investigation and make recommendations in the matter. The appointment shall not deprive the placing agency of standing to appear at the hearing and contest the adoption. Personal appearance at the hearing by a representative of the approved agency conducting the investigation may be dispensed with by the court if the agency's report favors the adoption. If an appearance is required, the approved agency shall be entitled to present testimony and to cross-examine witnesses and shall be subject to cross-examination with respect to its report and recommendations in the matter. The appearance of the child to be adopted shall not be required unless ordered by the court or unless the inquiry pursuant to section 13 of P.L. 1977, c.367 (C.9:3-49) indicates that the child is opposed to the adoption.
