If you are being asked for an Affidavit of Sole Custody in the Philippines, it is usually because a school, embassy, airline, DFA passport officer, DSWD travel clearance officer, or foreign immigration authority wants proof of who has legal responsibility for a child. The most important thing to know is this: an affidavit is a sworn written statement, not a court decision. It can help prove facts that are already supported by Philippine law or documents, but it cannot magically remove the rights of another parent if the law requires a court order.

What Is an Affidavit of Sole Custody?

An Affidavit of Sole Custody is a notarized statement where a parent or legal custodian declares that they have sole custody, sole parental authority, or actual care and control of a minor child.

In practical use, it is commonly requested for:

Applying for a child’s Philippine passport
Visa applications for the child
School enrollment or transfer
Medical authorization
DSWD travel clearance for minors
Immigration or relocation requirements abroad
Explaining the absence, death, abandonment, or non-involvement of the other parent

In Philippine law, the more accurate term is often parental authority. Parental authority means the rights and duties of parents over the person and property of their unemancipated minor children. Under the Family Code, parental authority includes caring for the child, keeping the child in the parent’s company, supporting the child, educating the child, and making important decisions for the child. (Lawphil)

Once properly notarized, an affidavit becomes a public document for evidentiary purposes. However, notarization does not prove that every statement inside the affidavit is legally correct. It only confirms that the person personally appeared before the notary, was identified, and swore to the document. (Supreme Court E-Library)

Is an Affidavit of Sole Custody the Same as a Court Order?

No. This is where many people get confused.

An affidavit is a self-declaration. A court order is an official ruling issued by a judge after a legal process.

An affidavit may be enough when the legal basis for sole custody is already clear, such as when an unmarried mother is proving custody over her illegitimate child. But if there is a dispute, a married parent claiming sole custody, a father of an illegitimate child claiming custody over the mother, or a guardian claiming authority over both parents, an affidavit alone is usually not enough.

Situation	Is an affidavit usually enough?	When a court order may be needed
Unmarried mother of an illegitimate child	Often yes	If custody is disputed or another authority asks for a court order
Married parents who are separated	Usually no	If one parent wants sole custody despite joint parental authority
Father of an illegitimate child	Usually no	If he wants sole custody or sole parental authority
Surviving parent after the other parent dies	Often with death certificate	If there is a dispute with relatives or guardians
Grandparent, aunt, uncle, sibling, or other custodian	Usually not enough	If legal guardianship or custody must be formally established
Adoptive parent	Affidavit may support, but decree is key	Adoption decree or amended birth records are usually required
Child subject to an existing custody case	No	The court handling the case controls custody issues

Legal Basis for Sole Custody in the Philippines

Illegitimate children are generally under the sole parental authority of the mother

For many people searching this topic, the child was born outside marriage. Under Article 176 of the Family Code, as amended, illegitimate children are under the parental authority of their mother and are entitled to support. (Lawphil)

The Supreme Court has repeatedly applied this rule. In Briones v. Miguel, the Court held that an illegitimate child is under the sole parental authority of the mother, and that the father’s recognition of the child does not automatically give him custody or parental authority. The father may have visitorial rights and support obligations, but the mother cannot be deprived of custody unless there are compelling reasons showing her unfitness. (Supreme Court E-Library)

This is why an unmarried mother often uses an Affidavit of Sole Custody to prove that she is the person legally authorized to decide for the child.

Using the father’s surname does not give the father custody

Republic Act No. 9255 allowed an illegitimate child to use the father’s surname if the father expressly recognizes the child through the proper documents, such as an Affidavit to Use the Surname of the Father. PSA rules explain how recognition and surname use are recorded, including through local civil registrars and Philippine foreign service posts abroad. (Philippine Statistics Authority)

But this affects the child’s surname and civil registry record. It does not automatically transfer parental authority from the mother to the father. The child may use the father’s surname and still remain under the mother’s parental authority under Article 176. (Philippine Statistics Authority)

Legitimate children are generally under joint parental authority

If the child was born during a valid marriage, the starting point is different. Under Article 211 of the Family Code, the father and mother jointly exercise parental authority over their common children. (Lawphil)

This means one married parent usually cannot simply execute an affidavit saying “I have sole custody” if there is no legal basis. If the parents are separated, Article 213 provides that parental authority shall be exercised by the parent designated by the court, taking into account the best interests of the child. For children below seven years old, the law also states that no child under seven shall be separated from the mother unless the court finds compelling reasons. (Lawphil)

If the mother of an illegitimate child is absent, dead, or unfit, the father is not automatically next in line

A common real-life issue is this: the mother of an illegitimate child dies, disappears, works abroad, or is unable to care for the child. Can the biological father simply sign an affidavit of sole custody?

Not always.

In Spouses Gabun v. Stolk, the Supreme Court explained that when parental authority is solely vested in the mother of an illegitimate child, substitute parental authority may pass to the persons listed in the Family Code, such as the surviving grandparent, oldest sibling over 21, or actual custodian over 21, depending on the circumstances. The biological father is not automatically disqualified, but his custody must still be evaluated based on the child’s best interests. (Supreme Court of the Philippines)

This is why fathers of illegitimate children often need more than an affidavit if they are trying to prove sole legal custody.

Custody disputes are handled by the Family Court

If custody is contested, the proper court is generally the Family Court. Republic Act No. 8369, the Family Courts Act of 1997, gives Family Courts jurisdiction over custody, guardianship, support, and related cases involving children. Family Courts may also issue temporary custody or support orders while a case is pending. (Lawphil)

The Supreme Court’s Rule on Custody of Minors also governs custody petitions and habeas corpus cases involving minors filed before the Family Court. (Lawphil)

Who Can Usually Execute an Affidavit of Sole Custody?

The person who signs the affidavit should be the person with a real legal basis to claim custody or parental authority.

Common examples include:

The mother of an illegitimate child
- This is the most common and strongest non-court basis.
- Attach the child’s PSA birth certificate.
- If the child uses the father’s surname, explain that the child is still under the mother’s parental authority.
A surviving parent
- Attach the other parent’s death certificate.
- If the child is legitimate, the surviving parent generally continues parental authority unless there is a legal reason otherwise.
A parent with a court custody order
- Attach the court order, judgment, or approved compromise agreement.
- The affidavit should not replace the order; it should summarize it.
A legal guardian
- Attach the guardianship order or letters of guardianship.
- A notarized affidavit alone does not usually create guardianship.
An adoptive parent
- Attach the adoption decree or amended birth certificate.
- The affidavit may be used only as supporting proof.

Step-by-Step: How to Get an Affidavit of Sole Custody in the Philippines

1. Identify your legal basis for claiming sole custody

Before drafting anything, be clear why you can claim sole custody.

Ask yourself:

Is the child illegitimate and am I the mother?
Was there a court order giving me custody?
Is the other parent deceased?
Is the other parent absent, unknown, or has abandoned the child?
Am I a legal guardian appointed by a court?
Is there an existing custody dispute?

This matters because the affidavit must match the law and the facts. A receiving office may reject a document that simply says “I have sole custody” without explaining why.

2. Gather supporting documents

At minimum, you will usually need the child’s birth certificate and your valid ID. Depending on your situation, you may need more.

Document	Why it matters	Practical note
PSA birth certificate of the child	Proves identity, parentage, and legitimacy status	Check spelling, dates, and parent details carefully
Valid government ID of the affiant	Required for notarization	The notary must verify identity through competent evidence
PSA Certificate of No Marriage or CENOMAR	Often useful for unmarried mothers	Helps show the child was born outside marriage
Court custody order	Required if custody was decided by a court	Bring certified true copies if available
Death certificate of the other parent	Supports claim of surviving parent authority	Use PSA copy if death was registered in the Philippines
Child’s passport or school ID	Useful for travel, school, or visa purposes	Make names consistent with the birth certificate
DSWD travel documents	Needed if the child will travel abroad without a parent or with a non-parent	Requirements depend on who will accompany the child
Foreign documents	Needed if birth, death, custody, or marriage records were issued abroad	May need apostille, consular notarization, or certified translation

3. Draft the affidavit clearly and specifically

A good Affidavit of Sole Custody should not be vague. It should tell the receiving office exactly who the child is, who the parent or custodian is, and what legal basis supports the claim.

The affidavit commonly includes:

Full name, age, citizenship, civil status, and address of the person signing
Child’s full name, date of birth, place of birth, and birth certificate details
Relationship of the affiant to the child
Whether the child is legitimate or illegitimate
Whether the other parent is absent, deceased, unknown, uninvolved, or subject to a court order
Current living arrangement of the child
Statement that the affiant has actual custody and care of the child
Legal basis for sole parental authority or custody
Purpose of the affidavit
Statement that the facts are true and correct
Jurat or notarial portion

For an unmarried mother, the affidavit should usually say that the child was born outside a valid marriage and that, under Article 176 of the Family Code, the mother exercises parental authority over the child.

For a parent with a court order, the affidavit should identify the court, case number, date of order, and specific custody terms.

4. Avoid overclaiming

Do not say “the other parent has no rights” unless a court has actually said so. In many cases, the other parent may still have support duties, visitation rights, or the right to be heard in court.

For example, the father of an illegitimate child may not have parental authority equal to the mother, but he may still be required to support the child and may seek visitorial rights. The Supreme Court recognized this distinction in Briones v. Miguel. (Supreme Court E-Library)

A careful affidavit is stronger than an exaggerated one.

5. Sign the affidavit before a notary public

In the Philippines, the affidavit must be signed in front of a notary public. The person signing should personally appear, present valid identification, and swear to the truth of the document.

A notary should not notarize a document if the signer did not personally appear or was not properly identified. The Supreme Court has emphasized that notarization is not an empty formality; it requires personal appearance and competent proof of identity. (Supreme Court E-Library)

Bring:

Printed affidavit
Original valid ID
Photocopy of valid ID
Supporting documents
Extra copies for stamping and submission

Many offices, embassies, and schools prefer an affidavit issued recently, often within the last three or six months, even if there is no single national rule on expiry.

6. If you are abroad, use consular notarization or apostille

If the affidavit is signed outside the Philippines but will be used in the Philippines, it should usually be either:

Notarized or acknowledged before a Philippine Embassy or Consulate; or
Notarized locally and then apostilled by the competent authority in the foreign country, if that country is part of the Apostille Convention.

Philippine posts explain that affidavits and similar private documents may be notarized at the embassy or consulate with personal appearance, while apostille is an alternative when the document is processed through the foreign country’s apostille system. (Philippine Embassy)

For countries that are not apostille members, consular authentication or legalization may still be required. Philippine consulates also note that documents notarized by a Philippine embassy or consulate generally do not need a separate apostille for use in the Philippines. (melbournepcg.org)

Sample Statements Commonly Included in an Affidavit of Sole Custody

The exact wording depends on your facts, but useful clauses often look like this:

I am the biological mother of [child’s full name], born on [date] in [place], as shown by the child’s PSA-issued Certificate of Live Birth.

The child was born outside a valid marriage. Under Article 176 of the Family Code of the Philippines, I exercise parental authority over my illegitimate child.

The child has been living with me since [date/place], and I have been solely responsible for the child’s daily care, support, education, health, and welfare.

No court has issued an order removing, suspending, or transferring my parental authority over the child.

I am executing this affidavit to attest to my sole parental authority and actual custody over the child for [passport application / visa application / school enrollment / travel clearance / other purpose].

If there is a court order, include something like:

By virtue of the Order dated [date] issued by Branch [number] of the Regional Trial Court/Family Court of [place] in [case title and number], custody of the minor child was granted to me.

If the other parent is deceased:

The child’s other parent, [name], died on [date], as shown by the attached death certificate. Since then, I have continuously exercised care, custody, and parental authority over the child.

Affidavit of Sole Custody for Passport Applications

Under Republic Act No. 11983, the New Philippine Passport Act, passport applications for minors may generally be filed by either parent. If the application is filed by a person other than a parent, a special power of attorney executed by the person exercising parental authority must be presented. The law also recognizes special situations involving legal guardians and foundlings. (Lawphil)

In practice, DFA passport officers may ask for additional documents depending on the child’s status and who appears with the child. For an illegitimate child, the mother’s authority is usually supported by:

PSA birth certificate
Mother’s valid ID
Child’s valid ID or school ID, if available
Affidavit of Sole Custody or similar affidavit, if requested
Other DFA-required documents for minors

For a father of an illegitimate child, the DFA or another receiving authority may ask for proof beyond recognition of paternity, especially if the mother is not present.

Affidavit of Sole Custody for DSWD Travel Clearance

DSWD travel clearance rules are very important when a Filipino minor is traveling abroad.

Based on DSWD guidance, a travel clearance is generally required for a Filipino minor traveling alone, with a person other than a parent, or in certain situations involving illegitimate children traveling with the biological father. DSWD also states that an illegitimate child traveling with the biological mother is exempt from travel clearance, while a biological father of an illegitimate child may need a court order to qualify for exemption or a certificate of exemption. (DSWD-MTA)

DSWD’s Minors Traveling Abroad system provides for online application, documentary review, and issuance timelines. The agency indicates that processing may take up to three working days after complete submission, with a stated processing fee of ₱300, and that travel clearance may not be issued in a custody dispute without the proper court order. (DSWD-MTA)

For DSWD purposes, an affidavit may help explain custody, but it may not replace:

Written consent of the parent or legal guardian, when required
Court custody order, when required
Death certificate of a deceased parent
Guardianship order
Adoption documents
Proof of relationship to the child
Travel itinerary and companion details

Fees, Timelines, and Where to Process

Item	Where to process	Typical timeline	Practical notes
Affidavit drafting	Lawyer, legal document preparer, or self-prepared	Same day to a few days	Make sure facts match PSA and court records
Notarization in the Philippines	Notary public	Same day	Personal appearance and valid ID are required
PSA birth certificate	PSA channels or authorized outlets	Varies	Get a recent copy when possible
CENOMAR	PSA	Varies	Useful for unmarried mothers when an office asks proof of non-marriage
Consular notarization	Philippine Embassy or Consulate	Depends on appointment and post	Personal appearance is usually required
Apostille abroad	Competent authority in the foreign country	Varies by country	Usually needed when locally notarized abroad for Philippine use
DSWD travel clearance	DSWD MTA system	Up to 3 working days after complete submission	Requirements depend on who travels with the child
Court custody order	Family Court	Often months or longer	Needed for disputed custody or legally complex situations

Common Reasons an Affidavit of Sole Custody Gets Rejected

The affidavit claims sole custody without legal basis

This often happens when married parents are separated but there is no court order. If the child is legitimate, both parents generally share parental authority unless a court has ruled otherwise.

The father of an illegitimate child relies only on the birth certificate

Being named on the birth certificate, signing an acknowledgment, or allowing the child to use the father’s surname may prove paternity. It does not automatically give the father sole custody.

The affidavit ignores an existing custody dispute

If there is a pending court case, a barangay dispute, or a written objection from the other parent, some agencies will not rely on a simple affidavit. A court order may be required.

The document was notarized improperly

A notarized affidavit may be questioned if the signer did not personally appear before the notary, used insufficient identification, or signed abroad before a local notary without apostille or consular authentication.

The names do not match

Small differences can cause big delays. Check the spelling and order of names in:

PSA birth certificate
Passport
School records
Court orders
Affidavit
IDs of the parent or custodian

If the child has a different surname in school records or foreign documents, explain the discrepancy and attach supporting proof.

The affidavit is too old

Some receiving offices want a recently executed affidavit. Even if the legal facts have not changed, an old affidavit may be rejected because the office wants current confirmation of custody and travel consent.

Special Issues for Foreigners and Overseas Filipinos

If the child or parent is abroad

If the affidavit is signed abroad and used in the Philippines, use a Philippine Embassy or Consulate notarization when available. Otherwise, local notarization followed by apostille may be accepted if the country is an apostille member. (Philippine Embassy)

If documents are in a foreign language

Foreign birth certificates, custody orders, death certificates, or marriage records may need:

Certified English translation
Apostille or consular authentication
Clear identification of the child and parents
Consistency with Philippine civil registry records

If there is a foreign custody order

A foreign custody order may be useful evidence, but it may not automatically settle all Philippine administrative issues. If a Philippine agency or court needs to act on custody, it may require properly authenticated copies and, in some cases, a Philippine court proceeding.

If the child is Filipino and illegitimate

Philippine law on parental authority may still be highly relevant, especially for Philippine passport, travel clearance, and civil registry matters. A foreign father’s recognition of the child does not automatically override the mother’s parental authority under Philippine law.

Frequently Asked Questions

How do I get an Affidavit of Sole Custody in the Philippines?

Prepare a written affidavit stating your identity, the child’s identity, your relationship to the child, your legal basis for sole custody, the child’s current living arrangement, and the purpose of the affidavit. Then sign it personally before a notary public with valid ID and supporting documents.

Can an unmarried mother get an Affidavit of Sole Custody without going to court?

Usually, yes. If the child is illegitimate, Article 176 of the Family Code places the child under the parental authority of the mother. A notarized affidavit, together with the PSA birth certificate, is often used to prove this for administrative purposes. (Lawphil)

Does the father’s name on the birth certificate give him custody?

No. For an illegitimate child, recognition of paternity may affect support, surname, and civil status records, but it does not automatically give the father parental authority over the child. The mother remains the parent with sole parental authority unless the law or a court order provides otherwise. (Supreme Court E-Library)

Does RA 9255 change custody if the child uses the father’s surname?

No. RA 9255 allows an illegitimate child to use the father’s surname when properly recognized, but it does not transfer custody or parental authority to the father. The child may use the father’s surname while still being under the mother’s parental authority. (Philippine Statistics Authority)

Can the biological father of an illegitimate child execute an Affidavit of Sole Custody?

He can execute an affidavit stating facts within his personal knowledge, but that does not automatically make him the legal custodian. If the mother is alive and has not been declared unfit, the father will often need a court order to establish sole custody or legal authority over the child.

Is an Affidavit of Sole Custody enough for a child’s passport?

It depends on the child’s status and who is applying. For an illegitimate child applying with the mother, the affidavit may support the application if requested. If a non-parent applies, or if the father of an illegitimate child applies without the mother, additional documents such as a special power of attorney, court order, or proof of legal authority may be required under passport rules. (Lawphil)

Is an Affidavit of Sole Custody enough for DSWD travel clearance?

Not always. DSWD requirements depend on who the child is traveling with, the child’s legitimacy status, and whether custody is disputed. DSWD may require parental consent, court orders, guardianship papers, or other documents. In custody disputes, DSWD may require a court order before issuing travel clearance. (DSWD-MTA)

How long is an Affidavit of Sole Custody valid?

There is no single national expiration period for all affidavits of sole custody. However, many embassies, schools, airlines, and government offices prefer recently notarized affidavits, commonly within three to six months. Always check the specific receiving office’s requirement.

Can I make an Affidavit of Sole Custody while abroad?

Yes. You may sign it before a Philippine Embassy or Consulate, or sign before a local notary and have it apostilled if the country is part of the Apostille Convention. If the country is not an apostille member, consular legalization may be required. (melbournepcg.org)

What if the other parent is missing, absent, or refuses to sign?

State the facts truthfully in the affidavit and attach proof if available, such as messages, death certificate, court records, police or barangay records, or proof that the child has been living with you. But if the receiving office requires the other parent’s consent or there is a dispute, you may need a Family Court order.

Key Takeaways

An Affidavit of Sole Custody is a sworn statement, not a court order.
For an illegitimate child, the mother generally has sole parental authority under Article 176 of the Family Code.
A father’s recognition of an illegitimate child or use of the father’s surname under RA 9255 does not automatically give the father custody.
For legitimate children, parental authority is generally joint unless a court designates one parent.
Fathers, grandparents, relatives, and other custodians may need a court order if their authority is not clear.
Always attach supporting documents such as PSA birth certificate, valid ID, death certificate, court order, guardianship papers, or travel documents.
If the affidavit is signed abroad, use Philippine consular notarization or apostille.
For passport, visa, school, and DSWD travel clearance purposes, the receiving office may require documents beyond the affidavit.
