Document Checklist for Filing an Annulment or Nullity Petition in the Philippines

Before you can file a petition for annulment or declaration of absolute nullity, you need more than a lawyer and a ground under the Family Code — you need a specific set of civil-registry records, identity documents, and proof tied to your residency and your ground. Gathering these before your first consultation saves time, and it often shortens how long your lawyer spends on preliminary work you can do yourself. This guide lists what is actually needed to file, what commonly supports the specific ground alleged, and what is required afterward to register a favorable decision and get your PSA marriage certificate annotated.

Direct Answer

To file a petition for annulment or declaration of absolute nullity in a Philippine Family Court, you generally need: a PSA-certified copy of your marriage certificate, PSA-certified birth certificates for you, your spouse, and any common children, a valid government-issued ID, proof of the residency that establishes venue, the verified petition itself (personally signed under A.M. No. 02-11-10-SC), and evidence specific to your ground — for example a psychological evaluation report in most Article 36 cases, or medical and documentary proof for an Article 45 ground such as a concealed sexually transmissible disease or a prior undissolved marriage. After a favorable, final decision, a separate set of documents — the court’s decree, the Certificate of Finality, and the Certificate of Registration — is required to get the PSA to annotate your marriage certificate. No single checklist fits every case; your lawyer or the Public Attorney’s Office (PAO) will tell you which items apply to your specific ground and circumstances.

Decision Snapshot

  • Applies to: Anyone preparing to file, or already filing, a petition for annulment (Article 45) or declaration of absolute nullity (Article 36 or Articles 35, 37, 38) of marriage in a Philippine Family Court.
  • Governing rule: A.M. No. 02-11-10-SC, Sections 2, 4, 5, and 6, and Family Code Articles 36, 45–46 and 50–52.
  • What changes the list: Your specific ground, whether you have common children or conjugal property, and whether your spouse’s whereabouts are known.
  • Easy-to-miss category: The documents needed after the decision — the Certificate of Finality and Certificate of Registration — are different from the documents needed to file, and are just as necessary before your civil status is reflected on your PSA record.
  • First action: Request certified true copies of your PSA marriage certificate and birth certificate now, since PSA processing can take time and a missing or defective record is one of the most common causes of delay.

Key Takeaways

  • A.M. No. 02-11-10-SC Section 5 requires the petition’s verification and certification against forum shopping to be signed personally by the petitioner — no petition may be filed solely by counsel or through an attorney-in-fact.
  • Civil-registry documents (PSA marriage certificate, birth certificates) establish the marriage and the parties’ identities and are needed in every case, regardless of ground.
  • The specific evidence you need beyond those civil-registry documents depends entirely on your ground — an Article 36 psychological-incapacity case and an Article 45 fraud case rely on different kinds of proof.
  • Venue depends on proof of residency for at least six months before filing, under Section 4 of A.M. No. 02-11-10-SC, so keep records that show where you or your spouse actually lived.
  • Winning your case does not end the paperwork: Article 52 of the Family Code requires the judgment to be registered before it binds other people, and a separate PSA annotation process requires its own set of post-decision certificates.
  • If you cannot afford a private lawyer, PAO requires its own income and merit-test documents, which are different from (and additional to) the documents needed for the petition itself.

Documents You Need Before You File

These are the baseline documents nearly every petitioner needs, regardless of ground. Confirm with your lawyer or PAO which certified copies your specific Family Court requires, since some courts ask for more than one certified copy for service on the Office of the Solicitor General and the public prosecutor.

Civil-registry and identity records

  • PSA-certified copy of your marriage certificate (the record the case is actually about).
  • PSA-certified birth certificates of both spouses, to establish identity, age, and citizenship.
  • PSA-certified birth certificates of any common children, since the court must address their legitimacy status, custody, support, and presumptive legitimes as part of the same case.
  • A valid government-issued ID for the petitioner (passport, driver’s license, UMID, or similar), for verification and court identification purposes.

Proof of residency, for venue

Section 4 of A.M. No. 02-11-10-SC requires the case to be filed where the petitioner or respondent has resided for at least six months immediately before filing. Courts commonly expect supporting proof such as a barangay certification of residency, utility bills or a lease in the petitioner’s name, a voter’s certification, or similar records covering that period. If either spouse is based abroad, the Supreme Court’s 2023 venue amendment requires additional consular certification of foreign residence — see FamilyCode.ph’s step-by-step guide to the annulment process for the specific overseas-petitioner rules.

The petition itself

The verified petition is drafted by counsel but must be personally signed by the petitioner. Under Section 5 of A.M. No. 02-11-10-SC, the verification and certification against forum shopping cannot be signed solely by counsel or by an attorney-in-fact — this is a document requirement in its own right, not just a formality, and a petition that skips it risks dismissal. The petition must also specifically allege the complete facts supporting the ground relied on, under Section 2.

Evidence That Commonly Supports Your Specific Ground

Beyond the baseline documents above, what you actually need to prove your case depends entirely on which ground you are alleging. The table below is a starting map, not an exhaustive list — discuss the specific proof available in your facts with your lawyer.

Ground Evidence commonly gathered Where to read more
Psychological incapacity (Art. 36) A clinical psychologist’s or psychiatrist’s evaluation report; lay-witness accounts of the behavior pattern. Expert testimony is persuasive but, after Tan-Andal v. Andal, not the only way to prove the condition. Psychological incapacity under Article 36
Fraud (Art. 46) Medical records, prior-conviction records, or other documentary proof of the specific concealed fact (pregnancy by another man, a loathsome STD, a prior conviction, drug addiction). Fraud grounds under Article 46
Lack of parental consent (ages 18–21) Birth certificate showing age at marriage; proof that no valid parental consent was obtained. Lack of parental consent
Unsound mind Medical or psychiatric records showing the condition existed at the time of marriage and was not known to the other party. Unsound mind as a ground
Serious, incurable STD Medical diagnosis and records showing the disease existed and was concealed at the time of marriage. STD as a ground
Bigamy or a prior undissolved marriage PSA records of the prior marriage, proof it was never validly dissolved before the second marriage. Bigamy and void marriages

Documents That Come Up During the Case

Once the case is filed, additional documents typically follow rather than precede the petition. The petitioner must serve copies of the petition on the Office of the Solicitor General and the public prosecutor within five days of filing, with proof of that service filed with the court. As the case moves through pre-trial and trial, your lawyer will prepare witness statements and documentary exhibits that support the specific ground alleged, and the public prosecutor’s collusion report becomes part of the record whenever no genuine answer is filed. If you and your spouse have conjugal or community property, be ready to produce titles, bank records, and other proof of acquisition, since Articles 50–51 require the court to address liquidation and the children’s presumptive legitimes before a decree can issue. None of this needs to be assembled before you file, but knowing it is coming helps you budget time and avoid surprises.

Documents You Need After a Favorable Decision

Many readers assume the paperwork ends when the judge rules in their favor. It does not. Two further sets of documents are needed before your civil status actually changes on official record.

To register the judgment. The entry of judgment and the decree must be registered with the civil registry where the marriage was recorded, and typically also where the Family Court sits, under Article 52 of the Family Code and Section 22 of A.M. No. 02-11-10-SC.

To get your PSA marriage certificate annotated. According to the Philippine Statistics Authority’s published civil-registration guidance, the documents generally required are the court’s Decree of Annulment or Declaration of Nullity, the Certificate of Finality, the Certificate of Registration from the local civil registry, and your un-annotated marriage certificate. These are filed through the Local Civil Registry Office (LCRO) where the marriage was registered, which endorses them to the PSA, or directly at the PSA’s Civil Registration System office. Confirm with the LCRO whether your documents have already been forwarded before requesting a duplicate submission. For the full registration sequence, see FamilyCode.ph’s guide on what happens after an annulment decision: appeal, entry of judgment and registration.

If You Are Applying Through PAO

If you cannot afford private counsel, the Public Attorney’s Office requires its own set of documents on top of the case documents above: an affidavit of indigency, and either a recent income tax return or pay slip, a certificate of indigency from the DSWD or local social welfare office, or a certificate of indigency or no income from your barangay chairperson. PAO also applies a merit test before taking a case. See FamilyCode.ph’s dedicated guide to free legal assistance through PAO for the full eligibility test and application steps.

Your Options and What to Do Next

Whichever path fits your situation, the first useful step is the same: find out what you already have and what is missing before you pay for anything.

  1. Request certified true copies now. Apply for PSA-certified copies of your marriage certificate and birth certificate (and your children’s, if any) through PSA’s online channels or a Serbilis outlet. If a record cannot be located, ask the LCRO for a specific certification of that fact rather than assuming the marriage or a required license does not exist.
  2. Match your ground to its specific evidence. Use the table above as a starting point, then bring what you already have — medical records, messages, prior civil-registry records — to your first consultation so your lawyer or PAO caseworker can tell you what else is realistically needed.
  3. If you may qualify for PAO, gather the indigency documents in parallel. Apply at your nearest PAO district office; the income-based test and required proof are separate from, and additional to, your case documents.
  4. If you are filing from abroad, secure the consular residence certification the 2023 venue amendment requires before you file, not after.
  5. Keep a dedicated case folder from day one, including a copy of everything you submit to the court, the sheriff’s return of service, and every certificate the court or civil registry issues — you will need several of these again at the registration and PSA-annotation stage.

Common Misunderstandings

  • “One checklist works for every annulment case.” It does not. Civil-registry and identity documents are common to every case, but the evidence that actually proves your ground depends entirely on which ground you allege.
  • “My lawyer can sign the petition’s verification for me.” No. Section 5 of A.M. No. 02-11-10-SC specifically requires the petitioner to sign the verification and certification against forum shopping personally.
  • “Once the judge rules in my favor, my documents are done.” Not yet. A separate, later set of documents — the Certificate of Finality and Certificate of Registration — is required before the PSA will annotate your marriage certificate.
  • “A missing PSA copy means there was no marriage or no license.” Not necessarily. It may simply mean the record needs to be requested, corrected, or specifically certified as missing; discuss the exact wording of any “no record” certification with your lawyer before drawing conclusions from it.

Practical Checklist

  1. PSA-certified marriage certificate.
  2. PSA-certified birth certificates for both spouses.
  3. PSA-certified birth certificates for any common children.
  4. A valid government-issued ID.
  5. Proof of residency covering at least six months before filing (barangay certification, utility bill, lease, or similar).
  6. Evidence specific to your ground (see the table above), gathered as early as possible.
  7. If applicable, titles, bank records, or other proof of conjugal or community property.
  8. If filing from abroad, consular certification of foreign residence.
  9. If applying through PAO, an affidavit of indigency plus proof of income or a barangay/DSWD certificate of indigency.
  10. A dedicated folder for every document the court, sheriff, or civil registry issues as the case proceeds.

Frequently Asked Questions

Do I need a psychological evaluation to file for annulment?

Only if your ground is Article 36 psychological incapacity, and even then, following Tan-Andal v. Andal (G.R. No. 196359, May 11, 2021), it is not the only way to prove the condition. Grounds under Article 45 that do not involve psychological incapacity generally do not need one at all.

What if I cannot find my PSA marriage certificate?

Request a certified true copy through PSA’s official channels first. If PSA or the local civil registrar cannot locate a record, ask for a specific written certification of that fact, since the exact wording matters for how your lawyer uses it in your case.

Can my lawyer sign and file the petition on my behalf while I am abroad?

No. The petitioner must personally sign the verification and certification against forum shopping. Overseas petitioners instead follow the Supreme Court’s 2023 venue amendment, which allows filing based on specific consular residence certification rather than personal appearance at every stage.

Do I need my children’s documents if we have no common children?

No. The requirement to submit children’s birth certificates and address their legitimacy, custody, and support only applies when the spouses have common children from the marriage.

Are the documents needed for PAO different from the documents needed for the case itself?

Yes. PAO’s income and merit-test documents (affidavit of indigency, proof of income, barangay or DSWD certificate) are in addition to, not instead of, the civil-registry and ground-specific documents your case itself requires.
