How to Get an Affidavit of Sole Custody for Illegitimate Children

In the Philippine legal system, the status of a child—whether legitimate or illegitimate—determines the primary framework for parental authority and custody. For mothers of illegitimate children, the Affidavit of Sole Custody serves as a vital legal instrument to assert their rights and facilitate various administrative processes, such as passport applications, school enrollments, and travel clearances.


The Legal Foundation: Article 176 of the Family Code

The primary basis for a mother’s claim to sole custody of an illegitimate child is found in Article 176 of the Family Code of the Philippines, as amended by Republic Act No. 9255.

The law explicitly states:

"Illegitimate children shall use the surname and shall be under the parental authority of their mother, and shall be entitled to support in conformity with this Code."

Under Philippine law, parental authority (which includes the right of custody) over an illegitimate child belongs solely and exclusively to the mother. This applies regardless of whether the father has recognized the child in the birth certificate or through a private handwritten instrument.

The "Tender Age" Rule

Furthermore, Article 213 of the Family Code provides that no child under seven years of age shall be separated from the mother unless the court finds compelling reasons to do otherwise. In the context of illegitimate children, this preference for the mother is even stronger, as the law does not grant the father any inherent right to joint custody unless a court order specifically mandates it.


When is an Affidavit of Sole Custody Required?

While the law automatically grants the mother custody, many government agencies and private institutions require a formal sworn statement to process transactions involving the minor. Common scenarios include:

  • DFA Passport Application: The Department of Foreign Affairs requires this affidavit if the mother is applying for a passport for her illegitimate child, especially if the child carries the father's surname.
  • DSWD Travel Clearance: If the child is traveling abroad without the mother, the Department of Social Welfare and Development (DSWD) requires proof of sole parental authority.
  • School and Medical Records: For enrollment or major medical decisions where the father is absent.
  • Insurance and Benefits: Claiming the child as a dependent in SSS, PhilHealth, or private insurance policies.

Key Elements of the Affidavit

An Affidavit of Sole Custody is a legal document where the mother declares under oath her status and her exclusive authority over the child. To be legally sufficient, it generally must contain the following:

  1. Personal Information: Full name, age, citizenship, and residence of the mother (the affiant).
  2. Child’s Details: Name and date of birth of the child.
  3. Statement of Illegitimacy: A declaration that the child is illegitimate and that the mother and father were never legally married.
  4. Reference to Law: Explicit mention of Article 176 of the Family Code as the basis for sole parental authority.
  5. Purpose: A statement explaining why the affidavit is being executed (e.g., "to comply with the requirements of the DFA").
  6. Signature and Notarization: The document must be signed by the mother and notarized by a licensed Notary Public.

Necessary Supporting Documents

When presenting the affidavit to authorities, it is almost always accompanied by:

Document Purpose
PSA Birth Certificate To prove the child's filiation and the mother's identity.
PSA Certificate of No Marriage (CENOMAR) To prove that the mother and father are not married.
Valid Government ID To verify the identity of the mother/affiant.

Important Limitations and Nuances

1. Recognition vs. Custody

A father's recognition of an illegitimate child (by signing the birth certificate) gives the child the right to use the father's surname and the right to receive support. However, recognition does not grant the father any right to custody. He may have "visitation rights," but the primary care and authority remain with the mother.

2. "Unfitness" of the Mother

The mother’s right to sole custody is not absolute. It can be challenged in court if the father or another interested party can prove that the mother is "unfit." Reasons for unfitness include:

  • Neglect or abandonment.
  • Physical or psychological abuse.
  • Drug addiction or habitual drunkenness.
  • Insanity.
  • Engaging in behavior that endangers the child's moral or physical development.

3. The Father's Role

Unless a court grants the father custody through a Petition for Habeas Corpus or a Petition for Custody (by proving the mother is unfit), his legal standing is limited to visitation rights and the obligation to provide financial support.


Summary of the Process

  1. Drafting: The mother prepares the affidavit or seeks legal assistance to ensure the language complies with current jurisprudence.
  2. Execution: The mother appears before a Notary Public to sign the document.
  3. Filing: The notarized affidavit is then submitted to the requesting agency (e.g., DFA, DSWD, or the Bureau of Immigration) along with the child's PSA birth certificate.

In the absence of a contrary court order, this affidavit stands as the definitive proof of a mother's unilateral right to make decisions for her child under Philippine law.
