How to Legitimate an Illegitimate Child in the Philippines: 2 Ways.

Raising the status of an illegitimate child to that of legitimate is important in cases of successional rights. It also bears importance in cases where the child was born prior to March 19, 2004 and the latter wants to use the surname of the father.

1. Legitimation.

Legitimation is a process whereby an illegitimate child becomes legitimate by virtue of the marriage of his or her parents.

Sec. 177 of the Family Code provides that a child conceived and born outside of wedlock to parents, who, at the time of conception of the child, were not disqualified by any impediment to marry each other may be legitimated.

As amended by Republic Act 98581, a child born to parents who were below 18 years old may also be legitimated.

To summarize, legitimation has three requirements that must all be met in order for it to push through:

  • The child is born out of wedlock;
  • The child’s parents at the time of conception were not disqualified from marrying each, regardless if they’re both below or above 18 years of age;
  • A subsequent valid marriage between the parents of the child.

Example: You got pregnant by your boyfriend prior to you getting married and both of you have no impediment to marry each other. The child is illegitimate but could be legitimated once you get married. In contrast, if both of you have an impediment to marry each other at the time of conception and birth of the child (e.g. if you are in a bigamous marriage), the child can not be legitimated.

How does legitimation take place?

A child is legitimated by the subsequent valid marriage of the parents. Once legitimated, the child shall enjoy the same rights as a legitimate child. Please note that legitimation is retroactive. It means that the child becomes legitimate at the time of his birth, not at the time of marriage of the parents. (Sec. 178, 179,180, Family Code)

Steps to take in recording the legitimation of a child by subsequent marriage.

Even though the marriage of your parents has upgraded your status from illegitimate to legitimate, you still need to go through the process of legitimation in order to officially change your status and be entitled to all the rights of a legitimate child.

1. Complete the following requirements for registration:

a. Certificate of Marriage

b. Certificate of Live Birth of the child

c. Affidavit of legitimation executed by both parents which shall contain the following facts:

  • Names of the parents;
  • The fact that at the time when the child was conceived, the parents could have contracted marriage, and that they subsequently contracted marriage;
  • The date and place of the marriage of the parent;
  • The name of the priest or solemnizing officer who officiated the marriage;
  • The name and municipality where such marriage was recorded
  • The name of the child to be legitimated and other facts of birth, and
  • The date and place where the birth of the child was registered.

2. Go to the Office of the Civil Registrar (the city or municipality) where the child was born.

3. Register the document.

4. Request a certified true copy of the PSA birth certificate once the process has been completed. Here are the effects of the legitimation:

  • The original family name of the child as appearing in the birth certificate shall not be erased or deleted.
  • In the remarks space of the COLB, the following shall be written: “Legitimated by Subsequent Marriage” indicating the family name which the child shall bear by virtue of the legitimation.
 

2. Adoption.

Republic Act No. 85522 or the “Domestic Adoption Act of the Philippines” provides that an illegitimate son or daughter of a qualified adopter may be adopted to improve the child’s status to that of legitimacy.

Example: In a situation where the child could not be legitimated because the parents have an impediment to marry each other at the time of the child’s conception and birth, the parent could adopt his or her own child so that the latter is now elevated to the status of a legitimate child.

Effects of adoption.

  • The child shall be considered the legitimate child of the adopting parent and thus entitled to all rights and obligations provided by law to a legitimate child
  • The effectivity of the decree of adoption shall be the date the petition for adoption was filed (Sec 13, RA 8552)
  • The original Certificate of Live Birth (COLB) of the child shall be stamped “canceled” with an annotation of the issuance of the amended COLB
  • An amended certificate of birth bearing the surname of the adopter shall be issued by the Civil Registry as required by the Rules of Court
  • All hearings in adoption cases shall be confidential and not open to the public. All records relating to the adoption proceedings shall be strictly confidential
  • The child shall have the same successional rights as the legitimate child
 

Frequently Asked Questions.

1. I have an illegitimate child/children from a previous relationship. Now that I’m married, my spouse and I want to legitimize my illegitimate child/children. Can we do it through adoption?

Yes, you can legitimize the child through the process of adoption. Once adopted, the child shall become the legitimate child of the adopters, and shall acquire the reciprocal rights and obligations as a parent and child. 

2. The illegitimate child has been using the father’s surname. Legitimization is needed in order for the child to claim citizenship to the father’s country or to claim rights to the father’s inheritance. However, the father has already passed away. Can the illegitimate child still be legitimized?

No, the child can no longer be legitimized. Given the death of the father, both options for legitimization as discussed in the article above have become impossible. Legitimation, or raising the status of the child from illegitimate to legitimate, occurs when the parents, later on, entered into a valid marriage. An illegitimate child may also become legitimate through the process of adoption, i.e. the parent shall adopt his or her illegitimate child. This is done to raise the status of the child from illegitimate to legitimate, which has effects on successional rights, among others.

      Your situation fits the first scenario.

  3. How can a person’s name be removed from a birth certificate? Like an ex husband, who is not the father of the child, but signed the birth certificate, acknowledging the child as his, on the late registration. He was the step dad, who wanted to raise the child as his own. And the child was subsequently legitimized, by NSO (then) by the marriage of mother & stepfather. Now, they’re divorced x20 years and mother & adult child wants to remove his name from the birth certificate. There’s actually a court order that he is not the biological father. And he didn’t formally adopt her.. just signed the birth certificate.

  5. Good day. I was reading the article how to legitimize an illegitimate child in the Philippines and I have a question. What about in this case, the man has illegitimate children and not married. He then plans to marry his present partner, not the mother of the children. How can the man’s children be legitimated when he marries his partner? Will the present partner need to adopt the children after their marriage? I would appreciate a reply. It will be a big help. Thank you.

  6. hi yong anak ko nakaregistered yong birth certh nya but hindi kami married pero now married kami after nyang ipinanganak.anong dapat kong gawin?mahal ba magpa change ng unmarried to married?thnks.

  7. How long does it take in the Philippines to process the legitimacy of the child’s birth once it is processed in the city civil registrar’s office?

  8. Hi Attorney Karen, My situation is the same, my Mom has a subsequent marriage when she was only 15 and when I was conceived I was not able to used my Dad’s (her 2nd husband) last name because they were not married. They later got married after a year when I was born however since she has a previous marriage that makes their marriage invalid. So even if I applied for legitimation in PSA it won’t push through because I have to provide the death cert of my Mom’s previous husband (which she don’t know if alive or not). Do I fall now to the adoption process?
