1. Mandatory Adoption Consents
Under Section 23 of Republic Act No. 11642, domestic administrative adoption requires the written consent of specific individuals to ensure the protection of family harmony and the child's welfare. For an adoption petition, mandatory consents include the adoptee if ten years of age or older, the biological parents of the child, the legitimate and adopted children aged ten years or older of the adopter, and the spouse of the adopter. Requiring these consents protects successional rights and maintains stability within the domestic household.

2. Spousal Consent Exception
Under Section 21 of Republic Act No. 11642, a married person may adopt independently without joining his or her spouse under specific statutory exceptions. One recognized exception occurs when the spouses are legally separated from each other. Where a decree of legal separation has been granted by a court, the legal tie of cohabitation and mutual spousal consent for adoption is severed. Consequently, a legally separated spouse can adopt independently without obtaining the written consent of the other spouse.

3. Adoption Without Separation
Under Section 21 and Section 23 of Republic Act No. 11642, a married person who is not legally separated may still adopt his or her own illegitimate child, provided that statutory conditions are met. However, because the marriage remains legally subsisting and unsevered by legal separation, the adopter must obtain the explicit written consent of his or her spouse. Obtaining spousal consent protects the conjugal harmony, property regime, and successional rights of the existing legitimate family.
