Process, Grounds, Requirements, Effects, and Practical Timelines

This article explains Philippine law and procedure governing the dissolution of marriages through annulment (voidable marriages) and declaration of nullity (void marriages). It synthesizes the Family Code, Supreme Court rules, and landmark jurisprudence, and is written for laypersons, law students, and practitioners alike.

I. Big Picture: Annulment vs. Declaration of Nullity

Two different legal remedies exist in the Philippines:

Declaration of Absolute Nullity (Nullity): For void marriages—those that were invalid from the start because an essential/formal requisite was absent or a prohibitive condition existed. Examples: no marriage license (with limited exceptions), bigamy, incestuous marriages, psychological incapacity under Article 36, marriages where a party was below 18, etc.
Annulment: For voidable marriages—those that were valid when celebrated but can later be annulled only by court decision because a defect existed at the time of marriage (e.g., lack of parental consent for 18–21-year-olds, fraud, force/intimidation, insanity, physical incapacity to consummate, or sexually transmissible disease).

Key consequences differ: prescription periods, legitimacy of children, property regimes, and the kind of decree the court issues.

II. Legal Bases

Family Code of the Philippines (Executive Order No. 209, as amended)
A.M. No. 02-11-10-SC (Rule on Declaration of Absolute Nullity of Void Marriages and Annulment of Voidable Marriages)
Selected jurisprudence (illustrative):
- Santos v. CA; Republic v. Molina (1997) – early guidance on Article 36
- Tan-Andal v. Andal (2021) – clarified that psychological incapacity is a legal concept, not a medical diagnosis; expert testimony is helpful but not indispensable, and incapacity must be grave, rooted in personality structure, and existing at the time of marriage (though it can manifest later).

III. Grounds

A. Grounds for Void Marriages (Nullity)

Common categories under the Family Code include:

Absence of essential/formal requisites
- No valid marriage license (except narrow statutory exceptions, e.g., certain cohabiting couples who execute a proper affidavit; note that documentary compliance is strictly scrutinized).
- Lack of authority of the solemnizing officer and the parties were not in good faith.
- No real consent (e.g., absolutely simulated marriage).
Marriages void by law
- Psychological incapacity (Article 36).
- Bigamous/polygamous marriages (a previous valid marriage still subsists; Article 40 requires a judicial declaration of nullity of the prior marriage before a subsequent marriage).
- Incestuous marriages (Article 37).
- Marriages void for public policy (Article 38), e.g., certain affinity/consanguinity relations.
- Child marriages: a party below 18 at the time of marriage—void ab initio; also criminalized by special law.
Defects in consent or ceremony so fundamental as to negate marriage.

Prescription: Actions for declaration of nullity do not prescribe—they may be filed at any time.

B. Grounds for Voidable Marriages (Annulment) – Article 45

Lack of parental consent (party was 18–21 and parental consent was absent)
Insanity (existing at the time of marriage)
Fraud (e.g., concealment of a prior conviction, pregnancy by another man, STD, homosexuality/sexual orientation per se is not fraud; jurisprudence is fact-specific)
Force, intimidation, or undue influence
Physical incapacity to consummate (incurable)
Sexually transmissible disease (serious and apparently incurable) existing at the time of marriage

Prescription: Annulment actions prescribe—typically 5 years from discovery/cessation of the defect (varies by ground). A spouse must file within the Family Code’s specific periods. If the aggrieved spouse freely cohabits after discovery or after intimidation ceases, the ground may be deemed waived.

IV. Who May File

Spouse (real party-in-interest).
In defined cases, a guardian, relative, or proper party (e.g., on insanity).
The State, through the Office of the Solicitor General (OSG), is a mandatory party in these cases to protect the institution of marriage; a public prosecutor also participates to investigate collusion.

V. Where to File (Venue) & What Court

Family Courts (Regional Trial Courts designated as such).
Venue generally in the province/city where the petitioner or respondent resides; special rules apply if the respondent is abroad or cannot be found.

VI. Core Procedure (Step-by-Step)

Pleading Stage
- Verified Petition stating the specific ground, material facts, and reliefs (status, custody, property, support, surname).
- Attach certification against forum shopping and supporting documents (copies of marriage certificate, birth certificates of children, proof of grounds, etc.).
Raffle & Summons
- Court raffle to a Family Court branch.
- Summons served on respondent; if unserved, service by publication may be allowed.
Participation of the State
- OSG is notified; public prosecutor investigates collusion and reports to the court.
Pre-Trial
- Mandatory. Issues are defined. Court-annexed mediation may tackle property, support, custody, but not the marital status itself (which is not compromise-able).
Trial
- Petitioner’s evidence (testimonial, documentary).
- Expert testimony (e.g., psychologist) is optional; after Tan-Andal, courts weigh the totality of evidence; contemporaneous acts and lay testimony are often pivotal.
- Respondent’s evidence, if any.
- Prosecutor may cross-examine to guard against collusion.
Decision
- Court grants or denies the petition; if granted, it specifies the ground and dispositive reliefs.
Finality & Registration
- After Entry of Judgment, the civil registrar issues/annotates the Decree of Nullity or Decree of Annulment.
- The decision and decree must be recorded in the Local Civil Registry where the marriage was recorded and transmitted to the Philippine Statistics Authority (PSA) for annotation.
Remarriage
- Only after the final decree is issued and civil registry records are properly annotated.
- For bigamy issues, Article 40 requires a prior final judicial declaration of the first marriage’s nullity before contracting a second marriage.

VII. Evidence & Practical Documentation

Typical documents and proofs include:

PSA-certified Marriage Certificate (and CENOMAR if relevant)
Birth Certificates of children
Affidavits and witness testimonies (family members, friends, co-workers)
Medical/psychological reports (helpful but not mandatory for Article 36)
Correspondence, photos, chats, emails, financial records (to prove patterns of behavior, abandonment, non-support, infidelity tied to legal grounds, etc.)
Proof of cohabitation duration, property acquisition records, and contributions (for property relations under Articles 147/148)

Tip: Courts look for concrete, contemporaneous acts showing incapacity at the time of marriage (for Article 36) or facts fitting the specific statutory ground (for annulment).

VIII. Effects of the Decree

A. On Marital Status

Parties become free to remarry after finality and proper annotation.

B. On Children

Voidable marriages (annulled): Children conceived or born before final judgment are legitimate.
Void marriages: Children are generally illegitimate, except those conceived or born under Article 36 (psychological incapacity)—they are legitimate by express provision of law.

C. On Property Relations & Money

If the marriage is void (Nullity):
- Article 147 (both parties not disqualified to marry and in good faith):
  - Properties acquired through joint efforts are held in co-ownership, generally equal shares unless proven otherwise by actual contributions; wages and salaries are presumed joint.
  - Children’s support and presumptive legitimes must be delivered from the net estate.
- Article 148 (one or both parties in bad faith or where the union is adulterous/bigamous):
  - Only actual contributions are recognized; no equal sharing presumption; if proven in bad faith, a party may forfeit benefits.
If the marriage is voidable (Annulment) and later annulled:
- The absolute community or conjugal partnership is dissolved and liquidated; the innocent spouse may be entitled to forfeitures in his/her favor and to damages in some cases.
Support, Custody, and Surnames
- Support for children is unaffected by the parents’ marital status; courts fix custody based on best interests of the child.
- A wife may resume her maiden name post-decree; the use of the husband’s surname is by custom and choice, not obligation.
Succession
- A void/annulled marriage generally ends rights of intestate succession between the former spouses going forward; vested rights prior to finality are treated per law.

IX. Timelines, Duration, and Practical Expectations

No fixed duration. Actual timelines vary widely by court docket, ground, witness availability, whether the respondent contests, and OSG participation.
A reasonable planning horizon is often ~1–3 years from filing to finality in straightforward, uncontested cases; longer if contested, if service requires publication, if witnesses are abroad, or if appeals occur.
Critical path items: completing evidence under Article 36, availability of the public prosecutor/OSG, and the prompt annotation of civil registry records after finality.

X. Costs (Indicative & Variable)

Filing and sheriff’s fees (court schedule-based).
Professional fees (attorney, possible psychologist/psychiatrist, document procurement, notarial fees).
Publication costs if summons by publication is necessary.
Travel/attendance costs for hearings.

Fees vary significantly by location, complexity, and professional engagement.

XI. Common Pitfalls & Practical Tips

Misgrounding: Choosing a ground that evidence cannot sustain (e.g., “incompatibility” alone is not psychological incapacity). Align your facts to the legal elements.
Article 36 specifics: Prove gravity, juridical antecedence (rooted before or at marriage), and incurability (or resistance to change), using patterns of behavior and credible witnesses; an expert is helpful but not strictly required.
Collusion is prohibited. Courts will not grant decrees where parties merely agree to end a marriage without a legal ground.
Remarriage timing: Do not remarry until the decree is final and annotated with the civil registry and PSA; otherwise, bigamy risk arises.
Property documentation: Keep receipts, bank records, titles, and proof of actual contributions—especially important under Articles 147/148.
Parallel church processes: Canon law (church annulment) is separate and does not produce civil effects. Only a civil court decree changes civil status.

XII. Frequently Asked Questions

1) Is a marriage automatically void if there was no license? No. The absence must be proven; there are exceptions (e.g., qualified cohabitation affidavits). Courts scrutinize documents and actual compliance.

2) Do I need a psychologist for Article 36? Not necessarily. After Tan-Andal, totality of evidence suffices; expert testimony can strengthen the case but is not indispensable.

3) Can we settle the case and agree to end the marriage? No. Status of marriage cannot be compromised. Parties may settle property/support issues, but the court must still find a valid legal ground to decree nullity/annulment.

4) Are children automatically illegitimate if the marriage is void? Generally yes, except children under Article 36 marriages, who are legitimate by law. Children from voidable marriages remain legitimate if conceived/born before the final judgment.

5) What if my spouse is abroad or cannot be found? The court may allow substituted service or service by publication with proper showing of diligence, which can extend timelines and increase costs.

XIII. Practical Checklist (Before Filing)

Clarify which remedy applies: Nullity (void) vs. Annulment (voidable).
Map facts to elements of the chosen legal ground.
Gather records: PSA/Local Civil Registry copies, IDs, proof of address, children’s documents.
Identify witnesses and secure affidavits (behavioral patterns, dates, incidents).
Consider whether expert evaluation is strategically helpful.
Budget for fees and logistics; anticipate service of summons challenges.
Plan for custody, support, and property proposals consistent with law.
Prepare for pre-trial and trial timelines; stay responsive to court/Osg/prosecutor directives.

XIV. Closing Notes

Philippine law protects marriage as an inviolable social institution, so courts grant decrees only upon clear proof fitting the statutory grounds.
A carefully prepared petition, credible witnesses, and organized evidence greatly improve the chances of success and can shorten timelines.
For personalized strategy and document review, consult a family law practitioner who regularly appears before the Family Courts in your locality.
