During said period, temporary parental authority shall be vested in the adopter(s). The court may motu proprio or upon motion of any party reduce the trial period if it finds the same to be in the best interest of the adoptee, stating the reasons for the reduction of the period. However, for alien adopter(s), he/she must complete the six (6)-month trial custody except for those enumerated in Sec. 7 (b) (i) (ii) (iii). If the child is below seven (7) years of age and is placed with the prospective adopter(s) through a preadoption placement authority issued by the Department, the prospective adopter(s) shall enjoy all the benefits to which biological parent(s) is entitled from the date the adoptee is placed with the prospective adopter(s).

Decree of Adoption. – If, after the publication of the order of hearing has been complied with, and no opposition has been interposed to the petition, and after consideration of the case studies, the qualifications of the adopter(s), trial custody report and the evidence submitted, the court is convinced that the petitioners are qualified to adopt, and that the adoption would redound to the best interest of the adoptee, a decree of adoption shall be entered which shall be effective as of the date the original petition was filed. This provision shall also apply in case the petitioner(s) dies before the issuance of the decree of adoption to protect the interest of the adoptee. The decree shall state the name by which the child is to be known. Section 14. Civil Registry Record. – An amended certificate of birth shall be issued by the Civil Registry, as required by the Rules of Court, attesting to the fact that the adoptee is the child of the adopter(s) by being registered with his/her surname.

All records, books, and papers relating to the adoption cases in the files of the court, the Department, or any other agency or institution participating in the adoption proceedings shall be kept strictly confidential. If the court finds that the disclosure of the information to a third person is necessary for purposes connected with or arising out of the adoption and will be for the best interest of the adoptee, the court may merit the necessary information to be released, restricting the purposes for which it may be used. ARTICLE V EFFECTS OF ADOPTION Section 16.
