In the Philippines, the distinction between a "legal" child and a child "reared as one's own" is a critical boundary in the law of succession. While many Filipino families practice de facto or informal adoption—where a child is taken in and raised by foster parents without judicial intervention—this emotional bond does not automatically translate into legal kinship.
Under the Civil Code and the Domestic Administrative Adoption and Alternative Child Care Act (RA 11642), the right to inherit is strictly tied to the legal status of the heir.
1. The Rule of Legal Filiation
The fundamental principle of Philippine succession law is that inheritance follows legal filiation. Only those with a legally recognized relationship to the deceased (the decedent) are entitled to succeed as compulsory heirs.
- Legitimate Children: Born of a valid marriage.
- Illegitimate Children: Filiation established through the birth certificate or an admission of paternity/maternity.
- Legally Adopted Children: Filiation established through a final decree of adoption issued by a court or the National Authority for Child Care (NACC).
Informally adopted children—often referred to as "foster children" or those under a de facto arrangement—do not possess legal filiation. Consequently, in the eyes of the law, they are considered strangers to the estate of the person who raised them.
2. Absence of Intestate Succession Rights
If a "parent" dies without a valid will (intestate), the law dictates the distribution of the estate. Under the Civil Code, the estate goes to the compulsory heirs.
Because an informal adoption has no legal standing, the child:
- Cannot inherit by operation of law.
- Cannot represent their "foster parent" in the inheritance of the foster parent’s own ancestors (Right of Representation).
- Is excluded by the deceased’s biological or legally adopted children, spouse, or even distant collateral relatives (like cousins or siblings of the deceased).
3. The Impact of RA 11642 (The New Adoption Law)
Prior to 2022, adoption was a purely judicial process. With the enactment of Republic Act No. 11642, the process became administrative. However, the law remains clear: filiation is not retroactive to the start of the informal care.
Until an Administrative Order of Adoption is issued by the NACC, the child remains a legal stranger. The law does provide a "Rectification of Simulated Birth" process for those whose birth records were falsified to show the foster parents as biological parents, but this requires a formal administrative filing to grant the child legal status and, by extension, inheritance rights.
4. Inheritance Through a Last Will and Testament
The only way an informally adopted child can inherit from their foster parents is through Testamentary Succession.
A person may include an informally adopted child in their Will. However, this is subject to strict limitations regarding the Legitime:
- The "parent" can only give the child a portion of the free portion of the estate.
- They cannot give the child any part of the estate that is reserved by law for compulsory heirs (legitimate children, spouse, etc.).
- If there are no compulsory heirs, the "parent" is free to bequeath the entire estate to the informally adopted child through a Will.
5. Simulation of Birth: A Legal Trap
It is common in informal adoptions for parents to "simulate" a birth—registering the child as their own biological offspring. Under the Social Adoption Act, simulation of birth is a criminal offense, though the law now provides amnesty and a path to legalization.
From an inheritance standpoint, a simulated birth certificate is voidable. If other legal heirs (such as the deceased's siblings or biological children) contest the child's status by proving the child is not a biological descendant and was never legally adopted, the child can be disqualified from inheriting, even if they have a birth certificate naming the deceased as the parent.
6. Summary Table of Rights
| Feature | Legally Adopted Child | Informally Adopted Child |
|---|---|---|
| Status | Equal to a legitimate child | Legal stranger |
| Intestate Rights | Automatic right to inherit | No right to inherit |
| Legitime | Entitled to a reserved share | No reserved share |
| Right of Representation | Yes | No |
| Requirement | Decree from Court or NACC | None (Emotional bond only) |
Conclusion
In the Philippine jurisdiction, love and long-term care do not create a right to inherit. For a child in an informal adoption to be protected, the foster parents must either undergo the Administrative Adoption process under RA 11642 to establish legal filiation or execute a Last Will and Testament to ensure the child receives a portion of the estate from the disposable free portion. Without these legal steps, the child remains vulnerable to total exclusion from the inheritance by operation of law.
