Adoption is often viewed as a way to provide a child with a permanent and loving family. However, many people are unaware of the significant legal rights that a child acquires once an adoption is finalized.

Under Republic Act No. 11642, or the Domestic Administrative Adoption and Alternative Child Care Act, adoption creates a legal parent-child relationship between the adopter and the adoptee. This relationship carries important rights and obligations that extend beyond day-to-day care and support.

Understanding these rights helps prospective adoptive parents, biological parents, and adoptees appreciate the legal effects of adoption and the protections it affords to children.

Once an adoption becomes effective, the adoptee is generally considered the legitimate child of the adopter for all intents and purposes under Philippine law. This means that the law recognizes the adoptive family relationship in the same manner as a biological parent-child relationship, subject to the provisions of applicable laws.

As a result, the child gains various rights that promote stability, security, and family integration.

Right to use the adopter’s surname

Adoption may also affect the child’s legal identity.

Following the adoption, the child may use the surname of the adopter in accordance with law and the terms of the adoption.

The adoption may likewise result in amendments to the child’s civil registry records, allowing official documents to reflect the new legal parent-child relationship.

Inheritance and succession rights

One of the most significant legal effects of adoption relates to inheritance.

Generally, an adopted child acquires rights of succession from the adoptive parent in the same manner as a legitimate child. This means the child shall be entitled to inherit from the adoptive parent, subject to the rules on succession under Philippine law.

These rights help ensure that adopted children enjoy the same legal protections and family security afforded to other children within the family.

What happens to the biological parents’ rights?

One of the most significant legal effects of adoption is the transfer of parental authority from the biological parent or parents to the adoptive parent or parents.

Under Section 42 of Republic Act No. 11642, upon the issuance of the Order of Adoption, the adoptive parents acquire full parental authority over the child. As a general rule, all legal ties between the biological parents and the adoptee are severed and vested in the adopters.

This means that the biological parents generally lose their rights and responsibilities as parents, including parental authority and the corresponding rights to make decisions concerning the child’s upbringing, education, healthcare, and welfare.

As an exception, in a step-parent adoption, the child does not lose their legal relationship with the biological parent who is married to the adopter. Instead, the adoptive step-parent joins that biological parent in exercising parental authority over the child. This allows the child to enjoy the legal benefits of having two recognized parents while preserving their existing family relationship.

Common misconceptions about adopted children’s rights

Several misconceptions continue to persist regarding adoption, including:

• Several misconceptions continue to persist regarding adoption, including:That adopted children have fewer rights than biological children;
• That adopted children cannot inherit from adoptive parents;
• That adoption only affects custody and not legal status;
• That adopted children remain legal outsiders within the adoptive family.

In reality, adoption is intended to create a permanent and legally recognized parent-child relationship that promotes the child’s best interests and long-term welfare.

International perspective on adoption

The rights afforded to adopted children in the Philippines are consistent with international child welfare principles.

For example, the United Nations Convention on the Rights of the Child (CRC), to which the Philippines is a party, recognizes that children are entitled to grow up in a family environment and that their best interests must be a primary consideration in all actions affecting them. Similarly, the Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption promotes safeguards to ensure that adoption serves the welfare and long-term stability of children.

These principles reinforce the importance of providing adopted children with security, permanence, and equal treatment within their families. With the implementation of Republic Act No. 11642, the Philippines has strengthened its commitment to these objectives by recognizing adoption as a means of securing a child’s right to a permanent, stable, and legally protected family environment.

To summarize

Adoption is more than a change in custody—it creates a legal parent-child relationship recognized by law.

Through adoption, a child shall acquire important rights relating to support, family membership, parental authority, use of a surname, and inheritance.

By understanding these legal effects, families can better appreciate how adoption promotes a child’s welfare and secures their place within a permanent family.
