Introduction

For Filipino families abroad, one of the most important post-birth legal steps is reporting the birth of a child to the Philippine government. This is commonly done through a Report of Birth filed with the Philippine Embassy or Consulate that has jurisdiction over the place where the child was born.

A frequent concern arises when only one parent is available: Can one parent register the child without the other parent physically appearing at the Philippine Embassy?

In many cases, yes. A parent may generally file a child’s Report of Birth before a Philippine Embassy or Consulate without the other parent being physically present. However, the answer depends on several factors, including the parents’ marital status, the child’s legitimacy or illegitimacy under Philippine law, the child’s surname, acknowledgment of paternity, custody issues, and the specific documentary requirements of the Embassy or Consulate.

This article discusses the Philippine legal context, consular practice, and practical issues surrounding the registration of a child abroad when one parent is absent.

1. What Is Being Registered?

When a child is born outside the Philippines, the child’s birth is not automatically recorded in the Philippine civil registry. The birth must be reported to the Philippine Embassy or Consulate with jurisdiction over the child’s place of birth.

This process is usually called a Report of Birth.

The Report of Birth is transmitted by the Embassy or Consulate to the Philippine Statistics Authority, or PSA. Once processed, the child may later obtain a PSA-certified copy of the Report of Birth, which serves as the Philippine civil registry record of the child’s birth abroad.

The Report of Birth is different from the foreign birth certificate. The foreign birth certificate proves the birth under the law of the country where the child was born. The Philippine Report of Birth records that birth for Philippine civil registry purposes.

2. Who May File the Report of Birth?

Generally, the Report of Birth may be filed by:

either parent;
both parents;
the legal guardian;
the person having charge of the child; or
another authorized person, depending on consular rules.

In ordinary cases, one parent may file the Report of Birth even if the other parent is not physically present.

However, the Embassy or Consulate may require documents from the absent parent if the facts of the case affect the child’s civil status, surname, nationality, custody, or parental authority.

3. Is the Other Parent’s Physical Presence Always Required?

No. The other parent’s physical presence is not always required.

Philippine consular posts commonly allow one parent to submit the Report of Birth on behalf of the child. But the absence of the other parent may matter if:

the parents are not married;
the child will use the father’s surname;
the father’s name is to be entered in the Philippine civil registry;
there is no proof of marriage;
there is a dispute between the parents;
the child’s citizenship claim depends on proof of Filipino parentage;
the Embassy requires notarized consent or acknowledgment from the absent parent;
the child is being issued a Philippine passport at the same time; or
the child’s documents contain inconsistencies.

Thus, the practical rule is:

One parent may often register the child alone, but the absent parent may still need to sign, acknowledge, consent, or provide identification depending on the circumstances.

4. The Importance of the Parents’ Marital Status

The parents’ marital status is one of the most important issues in determining what documents are required.

Under Philippine law, children are generally classified as either legitimate or illegitimate.

A child is generally legitimate if born or conceived during a valid marriage between the parents.

A child is generally illegitimate if born to parents who are not validly married to each other, unless otherwise covered by rules on legitimation or other specific legal provisions.

This distinction affects:

the child’s surname;
parental authority;
recognition by the father;
civil registry entries;
succession rights;
custody presumptions; and
documentary requirements at the Embassy or Consulate.

5. If the Parents Are Married

Where the parents are married, either parent can usually file the Report of Birth without the other parent being physically present.

The filing parent will typically need to submit:

the child’s foreign birth certificate;
the parents’ marriage certificate;
passports or identification documents of the parents;
proof of Filipino citizenship of one or both parents;
completed Report of Birth forms;
passport-sized photographs, if required;
proof of the child’s birth details;
applicable consular fees; and
other documents required by the specific post.

If the parents were married in the Philippines, the Embassy may require a PSA-issued marriage certificate.

If the parents were married abroad, the Embassy may require a Report of Marriage or foreign marriage certificate, depending on whether the marriage has already been reported to Philippine authorities.

If only one parent is present, the Embassy may still accept the application, especially if the marriage documents clearly establish the legal relationship of the parents and the filiation of the child.

6. If the Parents Are Not Married

If the parents are not married, the situation is more sensitive.

Under Philippine law, an illegitimate child is generally under the parental authority of the mother. The child usually uses the mother’s surname unless the father expressly recognizes the child and the requirements for using the father’s surname are satisfied.

This means that when the parents are not married, the absence of the father or mother may affect the filing, especially if the absent parent’s name, surname, or acknowledgment is involved.

A. If the Mother Files Alone

If the child is illegitimate and the mother files the Report of Birth alone, the Embassy may allow registration using the mother’s surname, especially if the father is not acknowledging the child or is not included in the record.

The mother will usually need to prove:

her identity;
her Filipino citizenship, if the child’s Philippine citizenship is claimed through her;
the child’s birth details; and
her relationship to the child.

If the father’s name is not to be included, or if the child will use the mother’s surname, the process may be simpler.

B. If the Father Files Alone

If the parents are not married and the father files alone, complications may arise.

If the child is illegitimate, the mother generally has parental authority. The Embassy may require the mother’s consent, identification, or participation, especially if the child’s surname, custody, or passport application is involved.

If the father wants the child to use his surname, he usually must execute an acknowledgment or admission of paternity in the legally required form.

C. If the Child Will Use the Father’s Surname

Philippine law allows an illegitimate child to use the father’s surname if the father expressly recognizes the child, usually through:

the record of birth appearing in the civil register;
an admission in a public document;
an admission in a private handwritten instrument signed by the father; or
other legally acceptable proof of filiation.

This is associated with Republic Act No. 9255, which amended Article 176 of the Family Code, allowing illegitimate children to use the surname of the father under certain conditions.

In consular practice, this may require an Affidavit of Admission of Paternity, Affidavit of Acknowledgment, or similar document. If the father is absent, the Embassy may require the acknowledgment to be notarized, authenticated, apostilled, or executed before a Philippine consular officer, depending on where it is signed.

7. Can the Father’s Name Be Placed on the Report of Birth If He Is Not Present?

Possibly, but it depends on the documents.

If the parents are married, the father’s name is generally entered based on the marriage and birth documents.

If the parents are not married, the father’s name may require proof of acknowledgment or admission of paternity.

The Embassy may not simply enter the father’s details based only on the mother’s statement if the father has not acknowledged the child in a legally acceptable manner. This is especially important because civil registry entries have legal consequences.

Where the father is absent but willing to acknowledge the child, he may need to sign an affidavit or acknowledgment document. If he is in another country, he may need to execute the document before a Philippine Embassy or Consulate, a local notary, or another authorized officer, subject to authentication or apostille requirements.

8. Can the Mother’s Name Be Placed on the Report of Birth If She Is Not Present?

Usually, yes, if the birth certificate and supporting documents clearly identify her as the mother.

The mother’s identity is generally established through the child’s birth record. However, if the mother is the absent parent and the father is filing, the Embassy may ask for the mother’s passport, identification, consent, or other documents, especially if the child is illegitimate or if a passport is also being applied for.

If the mother is the Filipino parent and the child’s Philippine citizenship depends on her, proof of her Filipino citizenship will be important.

9. Citizenship Issues

A child born abroad may be a Filipino citizen if, at the time of birth, at least one parent is a Filipino citizen.

The 1987 Philippine Constitution recognizes as Filipino citizens those whose fathers or mothers are citizens of the Philippines.

Thus, the child’s Philippine citizenship generally depends on the citizenship of either parent at the time of the child’s birth.

The Embassy or Consulate will usually require proof that at least one parent was a Filipino citizen when the child was born. This may include:

a valid Philippine passport;
PSA-issued birth certificate of the Filipino parent;
certificate of naturalization or reacquisition of citizenship;
identification certificate under dual citizenship rules;
oath of allegiance documents;
retention or reacquisition documents under Republic Act No. 9225; or
other proof of Philippine citizenship.

If the Filipino parent is absent, the registering parent must still provide sufficient proof of that parent’s citizenship.

10. What If the Filipino Parent Is the One Who Is Absent?

The child may still be reported as a Filipino if the absent Filipino parent’s citizenship and relationship to the child can be proven.

For example:

A foreign mother may file the Report of Birth for a child born abroad if the father is Filipino, but the Embassy will usually need documents proving the father’s Filipino citizenship and paternity.

A Filipino mother may file alone even if the foreign father is absent, provided the mother’s citizenship and maternity are established.

The key question is not merely physical presence, but proof.

The Embassy must be satisfied that the child is entitled to be recorded as a Filipino citizen under Philippine law.

11. Report of Birth vs. Philippine Passport Application

It is important to distinguish between registering the birth and applying for the child’s Philippine passport.

The Report of Birth records the child’s birth in the Philippine civil registry.

A passport application is a separate process. Passport rules may be stricter regarding parental presence, consent, custody, and identification.

For minors, the Department of Foreign Affairs generally has specific rules on who must accompany the child and what consent is required. If the child is illegitimate, the mother’s presence or authorization is often especially important because the mother generally has parental authority.

Thus, even if one parent can file the Report of Birth alone, that does not automatically mean the same parent can obtain the child’s Philippine passport without additional requirements.

12. Common Documents Required for Report of Birth

Requirements vary by Embassy or Consulate, but the following are commonly requested:

completed Report of Birth forms;
original and copies of the child’s foreign birth certificate;
English translation of the foreign birth certificate, if not in English;
passports or government-issued IDs of both parents;
proof of Filipino citizenship of one or both parents;
parents’ marriage certificate, if married;
Report of Marriage, if applicable;
affidavit of delayed registration, if the report is filed late;
affidavit of acknowledgment or admission of paternity, if applicable;
affidavit to use the father’s surname, if applicable;
proof of legal name changes, if applicable;
divorce, annulment, or death documents, if relevant;
consular fees;
self-addressed envelope, if the post returns documents by mail; and
additional documents required by the specific Embassy or Consulate.

Some posts require multiple originals or photocopies. Some require personal appearance. Others allow filing by mail. The rules differ by country and post.

13. Delayed Registration

Many Embassies treat the Report of Birth as delayed if it is filed beyond the prescribed period, commonly one year from the child’s birth.

A delayed Report of Birth may require an Affidavit of Delayed Registration explaining why the birth was not reported earlier.

Delayed registration does not necessarily prevent the child from being registered, but it may increase documentary requirements and processing time.

14. What If the Other Parent Refuses to Cooperate?

If the other parent refuses to appear or provide documents, the available options depend on what the filing parent is trying to accomplish.

If the parents are married

The filing parent may still be able to proceed using the marriage certificate, the child’s birth certificate, and available identification documents.

If the parents are not married and the mother is filing

The mother may generally report the child using her surname and her own proof of citizenship, if the child’s Filipino citizenship is derived from her.

If the father is needed to acknowledge paternity

If the father refuses to acknowledge the child, the child may not be able to use the father’s surname through a simple consular filing. Proof of filiation may need to be established through legally acceptable documents or court proceedings.

If there is a custody dispute

The Embassy may be cautious and may require court orders, custody documents, or written consent before proceeding with related applications, especially passport issuance or travel documentation.

15. What If the Parents Are Separated?

Separation does not automatically prevent one parent from filing a Report of Birth.

If the parents are legally married, the child may still be presumed legitimate, subject to Philippine law on legitimacy and impugning legitimacy.

If there is a court order concerning custody, parental authority, or restrictions on travel documents, that order may affect what the Embassy will require.

If the parents are separated but not legally annulled or divorced in a way recognized under Philippine law, their marital status for Philippine purposes may remain relevant.

16. What If the Parents Are Divorced?

Divorce requires careful treatment under Philippine law.

If the parents were married and later divorced abroad, the effect of the divorce in the Philippines depends on several issues, including the nationality of the parties and whether the divorce is recognized under Philippine law.

For purposes of reporting a child’s birth, the Embassy will look at the child’s date of birth, the parents’ marital status at the time of birth, and the documents submitted.

If the divorce affects custody, surname, legitimacy, or the authority to act for the child, the Embassy may require additional documents.

A foreign divorce decree may need authentication, apostille, translation, or judicial recognition in the Philippines depending on the purpose for which it is being used.

17. What If One Parent Is Deceased?

If one parent is deceased, the surviving parent can usually file the Report of Birth, subject to submission of the deceased parent’s death certificate and other required documents.

If the deceased parent was the Filipino parent, proof of that parent’s Filipino citizenship at the time of the child’s birth remains important.

If the deceased father was not married to the mother and did not acknowledge the child during his lifetime, establishing paternity may be more complicated.

18. What If the Child Was Born Through Assisted Reproduction or Surrogacy?

Cases involving surrogacy, assisted reproduction, donor conception, or non-traditional parentage can be legally complex.

Philippine consular officers may require additional documents to determine:

who the legal parents are;
whether the child has a Filipino parent;
whether the foreign birth certificate is acceptable;
whether there are conflicting parentage laws;
whether a court order is needed;
whether the child’s citizenship claim is established; and
whether Philippine public policy concerns are involved.

In such cases, the physical absence of the other parent may be only one issue among many.

19. What If the Child Is Adopted?

A Report of Birth is generally for recording the facts of birth, not adoption.

If the child was adopted abroad, the parents may need to deal with adoption recognition, amended birth records, immigration documentation, or other Philippine legal processes.

Adoption cases should be distinguished from ordinary consular birth registration.

20. Surname Rules

Surname issues are often the reason the absent parent becomes important.

Legitimate child

A legitimate child generally uses the surname of the father, though Philippine law also recognizes rights relating to the mother’s surname in certain contexts.

Illegitimate child

An illegitimate child generally uses the mother’s surname, unless the father has acknowledged the child and the requirements for using the father’s surname are met.

Use of father’s surname by illegitimate child

If the child is illegitimate and will use the father’s surname, the father’s acknowledgment is usually necessary. The father’s physical presence may not be required if he executes the proper document elsewhere, but his legally valid acknowledgment is important.

21. Parental Authority and Custody

Under Philippine law, parental authority is generally exercised jointly by the father and mother over their legitimate children.

For illegitimate children, parental authority generally belongs to the mother.

This distinction matters in consular practice. A father of an illegitimate child may be recognized as the father for purposes of filiation, support, or surname, but that does not automatically give him parental authority equal to the mother.

Therefore, where an illegitimate child is involved, the Embassy may require the mother’s consent or presence for certain applications, especially passports.

22. Does the Absent Parent Need to Sign the Report of Birth Form?

Sometimes yes, sometimes no.

If the parents are married, one parent may often sign as informant or applicant, while the other parent’s details are supported by documents.

If the parents are not married and the father’s acknowledgment is needed, the father may need to sign a separate affidavit or acknowledgment.

If there are inconsistencies or special circumstances, the Embassy may require both parents’ signatures.

The controlling issue is not merely the Report of Birth form, but whether the civil registry facts being recorded are sufficiently supported.

23. Personal Appearance Requirements

Some Philippine Embassies or Consulates require personal appearance for certain civil registry services. Others allow applications by mail, courier, or authorized representative.

Where personal appearance is required, it may be required only from the filing parent, not necessarily both parents.

However, personal appearance may be required from the absent parent if:

that parent must execute an affidavit;
that parent’s consent is required;
identity verification is needed;
there are suspicious or inconsistent documents;
there is a dispute; or
the child is applying for a passport or travel document.

24. Special Issues When the Child Was Born Before the Parents’ Marriage

If the parents were not married when the child was born but later married, the child may possibly be legitimated if the legal requirements are met.

Legitimation under Philippine law generally applies when the parents were not disqualified by any impediment to marry each other at the time of the child’s conception and later validly marry.

If legitimation is relevant, the Embassy or Philippine civil registry may require additional documents. The child’s status and surname may be affected.

25. What If the Parents’ Names Differ Across Documents?

Name inconsistencies are common in consular registration.

Examples include:

maiden name vs. married name;
middle name differences;
spelling errors;
missing suffixes;
different transliterations;
foreign naming conventions;
incomplete names on foreign birth certificates;
different order of given name and surname; and
use of aliases.

If documents do not match, the Embassy may require affidavits, amended foreign records, PSA documents, or proof of identity.

The absence of one parent can make inconsistencies harder to resolve if that parent’s identity or consent must be verified.

26. What If the Foreign Birth Certificate Lists Only One Parent?

If the foreign birth certificate lists only one parent, the Report of Birth may usually follow the available evidence.

If the mother is listed and is the Filipino parent, the child may generally be reported based on her documents.

If the father is not listed but is being claimed as the Filipino parent, the Embassy may require strong proof of paternity and acknowledgment.

If the father is listed but the parents are not married, the listing may help, but the Embassy may still require acknowledgment documents depending on Philippine requirements.

27. What If the Child Has a Foreign Surname Different From the Philippine Surname?

A child born abroad may have a foreign birth certificate using a surname permitted by the law of the country of birth. Philippine surname rules may differ.

The Embassy may record the child’s name according to Philippine civil registry rules. This can result in differences between the foreign birth certificate and the Philippine Report of Birth.

For example, an illegitimate child may have the father’s surname on the foreign birth certificate, but Philippine authorities may require proper paternal acknowledgment before allowing use of the father’s surname in the Philippine record.

This issue should be handled carefully because later passport, school, immigration, and inheritance documents may be affected.

28. What If the Other Parent Is a Foreigner?

The other parent’s foreign nationality does not by itself prevent one parent from filing.

If one parent is Filipino, the child may be a Filipino citizen from birth. The foreign parent’s documents may still be required to complete the child’s civil registry record.

If the foreign parent is absent, the filing Filipino parent may need to provide:

copy of the foreign parent’s passport;
foreign parent’s identification;
marriage certificate, if married;
acknowledgment of paternity, if not married and relevant;
consent, if required for passport or related services; and
translated or authenticated documents, if applicable.

29. What If the Filipino Parent Has Become a Naturalized Citizen of Another Country?

The timing matters.

If the parent was still a Filipino citizen at the time of the child’s birth, the child may have acquired Philippine citizenship at birth.

If the parent had already lost Philippine citizenship before the child’s birth and had not reacquired it, the child’s claim may be affected.

If the parent reacquired Philippine citizenship under Republic Act No. 9225 before the child’s birth, documents proving reacquisition may be needed.

If reacquisition occurred after the child’s birth, the child’s citizenship situation may require closer legal analysis.

30. Can a Representative Register the Child Instead of a Parent?

Some Embassies or Consulates may allow filing through an authorized representative, especially for mailed applications or where personal appearance is not required.

The representative may need:

authorization letter;
special power of attorney;
valid identification;
original documents;
copies of parents’ passports;
completed forms; and
consular fees.

However, where affidavits, acknowledgments, or sworn statements are required, the relevant parent may still need to personally sign before an authorized officer.

31. Late, Incomplete, or Defective Registration

A Report of Birth may be delayed or complicated if:

the birth was reported years later;
the foreign birth certificate has errors;
the parents’ marriage was never reported;
the Filipino parent lacks proof of citizenship;
the parents are not married;
the child’s surname does not match Philippine law;
the father has not acknowledged the child;
the other parent refuses to cooperate;
the child is already an adult;
documents are in a foreign language;
names do not match; or
there are custody disputes.

In such cases, the Embassy may still accept the filing but require supplemental documents.

32. Adult Children Born Abroad

If the person whose birth is being reported is already an adult, the adult child may usually participate in or file the report, depending on consular rules.

The absence of one parent may still matter if parentage, citizenship, or surname must be proven.

For adult applicants, the Embassy may require the adult child’s identification, personal appearance, and proof of Filipino parentage at the time of birth.

33. Legal Effects of the Report of Birth

A Philippine Report of Birth may be used to establish:

Philippine civil registry record of birth;
Filipino citizenship from birth, if applicable;
filiation;
name and surname under Philippine records;
basis for Philippine passport application;
basis for school, immigration, and government transactions;
family records; and
potential rights under Philippine law.

However, the Report of Birth does not magically cure all legal defects. If paternity, legitimacy, citizenship, or custody is disputed, separate legal proceedings may be needed.

34. Can the Embassy Refuse to Register Without the Other Parent?

The Embassy may decline, defer, or require additional documents if the absence of the other parent prevents proper verification of the child’s civil registry details.

This is more likely where:

the parents are not married;
the absent parent’s citizenship is essential;
the absent parent’s acknowledgment is needed;
the child will use the absent father’s surname;
documents are inconsistent;
there is a dispute;
there are signs of fraud;
custody is unclear;
the child’s foreign record conflicts with Philippine law; or
the application is combined with passport issuance.

The Embassy’s role is not merely clerical. It must ensure that the report complies with Philippine civil registry law and documentary standards.

35. Practical Scenarios

Scenario 1: Married Filipino parents, mother files alone

The mother can usually file the Report of Birth without the father present, provided she submits the child’s birth certificate, parents’ marriage certificate, passports, and proof of citizenship.

Scenario 2: Filipino mother, foreign father, unmarried, mother files alone

The mother can usually report the child as Filipino through her citizenship. The child may generally use the mother’s surname unless the father properly acknowledges the child and the requirements for use of the father’s surname are met.

Scenario 3: Filipino father, foreign mother, unmarried, father files alone

This may require the mother’s participation or consent, especially because an illegitimate child is generally under the mother’s parental authority. The father may also need to prove paternity and Filipino citizenship.

Scenario 4: Foreign mother files for child of Filipino father, father absent

The Embassy will likely require proof that the father is Filipino and that he is legally recognized as the child’s father. If the parents are not married, acknowledgment documents may be required.

Scenario 5: Father wants child to use his surname but is abroad

The father may not need to appear at the same Embassy, but he may need to execute an acknowledgment or affidavit before a Philippine consular officer or other authorized official.

Scenario 6: Other parent refuses to give passport copy

The Embassy may still process some cases if the filing parent provides alternative proof, but lack of the other parent’s identification can delay or prevent completion depending on the facts.

Scenario 7: Report of Birth plus passport application

Even if one parent can report the birth alone, the passport application may require separate parental consent, appearance, or proof of custody.

36. Key Philippine Laws and Principles

The main Philippine legal principles involved include:

1987 Philippine Constitution — citizenship of children whose fathers or mothers are Filipino citizens.
Family Code of the Philippines — legitimacy, illegitimacy, parental authority, surname, and family relations.
Civil Registry Law and civil registration rules — recording births, marriages, and civil status.
Republic Act No. 9255 — use of the father’s surname by illegitimate children under certain conditions.
Republic Act No. 9225 — retention and reacquisition of Philippine citizenship by former natural-born Filipinos.
Passport laws and DFA regulations — separate rules for issuance of Philippine passports to minors.
Rules on authentication, apostille, and consular notarization — for foreign-executed documents.
Court rules on filiation, custody, and recognition of foreign judgments — where disputes or foreign court orders are involved.

37. Practical Checklist When One Parent Is Absent

A parent filing alone should prepare:

child’s original foreign birth certificate;
certified translation, if needed;
completed Report of Birth forms;
filing parent’s valid passport or ID;
absent parent’s passport or ID copy, if available;
proof of Filipino citizenship of the Filipino parent;
PSA birth certificate of Filipino parent, if required;
parents’ PSA marriage certificate, if married in the Philippines;
foreign marriage certificate or Report of Marriage, if married abroad;
affidavit of delayed registration, if late;
acknowledgment of paternity, if applicable;
affidavit to use father’s surname, if applicable;
custody documents, if relevant;
death certificate, divorce decree, annulment decree, or court order, if relevant;
proof of name change, if relevant;
copies required by the Embassy;
consular fees; and
return envelope, if filing by mail.

38. Common Mistakes to Avoid

Common mistakes include:

assuming the foreign birth certificate is enough for Philippine registration;
assuming both parents must always appear;
assuming one parent’s absence never matters;
failing to prove Filipino citizenship at the time of birth;
using the father’s surname without proper acknowledgment in illegitimate-child cases;
confusing Report of Birth with passport issuance;
submitting inconsistent names without explanation;
failing to report the parents’ marriage first, where required;
ignoring translation, apostille, or authentication requirements;
waiting many years without preparing a delayed registration affidavit;
assuming foreign custody rules automatically control Philippine consular practice; and
failing to distinguish between legitimate and illegitimate status.

39. The Core Rule

A parent can often register a child’s birth at a Philippine Embassy or Consulate without the other parent physically present.

However, the absent parent may still need to provide documents, identification, consent, or acknowledgment when required by Philippine law or consular rules.

The most important factors are:

whether the parents are married;
whether the child is legitimate or illegitimate;
whether the child will use the father’s surname;
whether the absent parent is the Filipino parent;
whether paternity or maternity is clearly established;
whether the child is also applying for a passport;
whether there are custody issues;
whether documents are complete and consistent; and
the specific requirements of the Embassy or Consulate.

Conclusion

In the Philippine context, the physical absence of one parent does not automatically prevent the registration of a child’s birth at a Philippine Embassy or Consulate. A Report of Birth may commonly be filed by one parent, particularly where the parents are married and the documents clearly establish the child’s birth, parentage, and Filipino citizenship.

The absence of the other parent becomes legally important when the parents are unmarried, when the child will use the father’s surname, when paternity must be acknowledged, when the absent parent is the Filipino parent, or when custody and passport issues are involved.

The safest legal understanding is this: personal appearance of both parents is not always required, but legal proof from both parents may be required depending on what facts must be recorded.
