13. In the case on hand, the decree of divorce between the biological parents clearly provides that custody of minor Harsh would be with the wife of the petitioner and respondent no.3 as former husband, has given up all his rights. The Deed of Adoption is a registered deed which is not challenged by anybody. On the contrary, as noted hereinabove, respondent no.3 who happens to be the biological father of the minor child Harsh has expressed by way of an affidavit before this Court in this petition unequivocally that he has no objection if the petitioner's name is substituted as father. Thus, as provided under section 16 of the Hindu Adoptions and Maintenance Act, 1956, minor Harsh is lawfully adopted and the Deed of Adoption is registered and therefore the presumption as per the provisions of section 16 of the Act can be drawn in favour of the petitioner as there is no rebuttal by the procedure known to the law. Following the ratio laid down by this Court in the case of N.R. Trivedi v. District Education Officer, Anand, AIR 2004 Guj S3, thus, from the record of this case, it appears that the presumption as regards adoption by a registered deed would be in favour of the petitioner.
