This article summarizes Philippine law as of 18 April 2025. It is for general information only and does not constitute legal advice. Always consult a Philippine lawyer for your particular circumstances.

1. Legal Foundations

Source	Key Provisions
1987 Constitution	Art. XV (marriage as “inviolable social institution”)
Family Code of the Philippines (E.O. 209, 1987, as amended)	Arts. 1‑54 (marriage); Arts. 35‑38, 41, 44 (void marriages); Art. 36 (psychological incapacity); Arts. 45‑47 (voidable marriages/annulment); Arts. 55‑67 (legal separation); Art. 26 §2 (recognition of foreign divorce)
Civil Code (for marriages before 3 Aug 1988)	Arts. 80‑91 (void/voidable)
Rules of Court / Supreme Court A.M. Nos. 02‑11‑10‑SC & 02‑11‑11‑SC (latest amendments 2023)	Special rules of procedure for petitions for nullity/annulment and legal separation
Special laws & jurisprudence	‑ Child & Youth Welfare Code, VAWC Act, etc.; landmark cases (see § 9)

2. Conceptual Map

Remedy	What It Attacks	Status After Decree	Right to Remarry?	Property Regime	Children’s Status
Declaration of Nullity	Void marriage (never valid)	Marriage is deemed never to have existed	Yes	No CPG/ACP ever arose; property divided per Art. 147 or 148	Legitimate if art. 36; illegitimate if incestuous/bigamous, etc.
Annulment	Voidable marriage (defective but valid until annulled)	Marriage set aside prospectively	Yes	Conjugal/ACP dissolved & liquidated	Legitimate
Legal Separation	Valid marriage with grave cause	Marriage remains; only bed‑and‑board separated	No	Conjugal/ACP separated; future earnings separate	Legitimate

ACP = Absolute Community of Property; CPG = Conjugal Partnership of Gains

3. Declaration of Nullity of Marriage (Void Marriages)

3.1 Grounds (Family Code)

Art.	Ground	Notes / Examples
35	Lack of essential/formal requisites (e.g., no marriage license, no authority of solemnizing officer)
36	Psychological incapacity — a party’s enduring inability to comply with essential marital obligations
37	Incestuous marriages between relatives in the direct line or within 3rd collateral degree
38	Marriages void by public policy (e.g., step‑parent & step‑child)
41	Spouse presumed dead & 2nd marriage contracted without the 4‑year (or 2‑year) statutory period + judicial declaration
53	Subsequent bigamous marriage where first marriage was not legally terminated

3.2 Evolving Doctrine on Psychological Incapacity

Santos v. CA (G.R. No. 112019, 1995) — first recognized Art. 36 remedy.
Republic v. Molina (G.R. No. 108763, 1997) — set the Molina guidelines (medical proof, gravity, juridical antecedence).
Tan‑Andal v. Andal (G.R. No. 196359, 11 May 2021) — liberalized the doctrine:
- Incapacity is a legal, not a strictly medical concept.
- Expert testimony helpful but not indispensable.
- Focus is on “incapacity to perform,” not mere difficulty or refusal.

3.3 Procedure (A.M. 02‑11‑10‑SC)

Verified petition in the Regional Trial Court (Family Court) where either spouse resides.
Service & Answer (15 days).
Pre‑trial — mandatory; possibility of mediation for collateral issues.
Trial — testimonies, expert evidence, social worker’s report, Judicial Affidavit Rule applies.
Decision; review by the Office of the Solicitor General (OSG).
Finality & Entry of Judgment; annotation with the local Civil Registry and PSA.

Provisional reliefs available: support pendente lite, child custody, injunctions, protection orders, use of family home.

3.4 Effects

Parties may remarry upon finality.
Property: If parties lived together in good faith (Art. 147), divide co-owned properties equally; otherwise apply Art. 148 (based on actual contributions).
Children: Legitimate except those from incestuous/void by public policy marriages.
Succession: Spouses cease to be intestate heirs of each other.

4. Annulment of Voidable Marriages

4.1 Grounds (Art. 45)

Ground	Prescriptive Period to Sue
Lack of parental consent (18‑21 yrs)	5 yrs after reaching 21
Insanity of a spouse	Any time before insane spouse regains sanity; or by insane spouse within 5 yrs after regaining
Fraud (Art. 46)	Within 5 yrs of discovery
Force, intimidation, undue influence	Within 5 yrs from cessation
Impotence (incurable physical incapacity)	Within 5 yrs after marriage
Serious sexually transmitted infection	Within 5 yrs after marriage

4.2 Procedure

Identical framework to nullity petitions. The State (OSG) is still an indispensable party.

4.3 Effects

Marriage dissolved only prospectively (Art. 47).
Conjugal/ACP dissolved and liquidated; presumptive legitime of spouse and children vested.
Custody/support resolved; woman may revert to maiden name.

5. Legal Separation

5.1 Grounds (Art. 55)

Repeated physical violence or moral pressure.
Physical violence to child or to petitioner’s parent.
Attempt to corrupt or induce spouse/child into prostitution.
Final conviction of spouse for attempt on life of petitioner.
Drug addiction or habitual alcoholism.
Lesbianism or homosexuality (not mere sexual orientation, but open cohabitation or infidelity).
Bigamous union.
Sexual infidelity or perversion.
Attempt by respondent to compel petitioner to change political or religious affiliation.
Abandonment without just cause for more than one year.

5.2 Strict Time Bars

Action must be filed within 5 years of the cause, except physical violence (at any time during marriage).
No collusion or condonation; condonation bars the action.

5.3 Procedure (A.M. 02‑11‑11‑SC)

Similar to nullity; additionally requires:

Cooling‑off period of 6 months after filing (except when violence exists).
Mandatory efforts toward reconciliation by the court.

5.4 Effects of Decree

Spouses live separately; no right to remarry.
Absolute separation of property; forfeiture of share in community property in favor of common children if the respondent is at fault.
Disqualification of guilty spouse to inherit intestate from innocent spouse (Art. 63).
Custody/support determined; family home automatically assigned to innocent spouse & children.

6. Recognition of Foreign Divorce (Art. 26 §2)

Applies when one spouse is a non‑Filipino.
The Filipino spouse may remarry once foreign judgment is recognized by a Philippine court.
SC En Banc Manalo v. Rep. (G.R. No. 221029, 2018) clarified that a Filipino may invoke a foreign divorce obtained by the other spouse (even if the divorce is unilateral).

7. Ancillary & Alternative Remedies

Judicial Separation of Property (Art. 134‑136, FC) — independent action when economic abuse exists.
Violence Against Women and Children (RA 9262) — protection orders; may run parallel with marital actions.
Petition to Change Surname of a Spouse or Child (RA 9048 as amended).
Summary judicial proceedings for presumptive death (Art. 41) when spouse has disappeared.

8. Recent Jurisprudence & Administrative Updates (2021‑2025)

Case / Rule	Gist
Tan‑Andal v. Andal (2021)	Psychological incapacity = legal concept; liberality.
Alcantara v. OSG (G.R. No. 252183, 2022)	Psychological incapacity need not be shown to be incurable; must simply be permanent/incapable of change within a reasonable period.
Supreme Court Bar Matter Res. No. 17‑09‑11‑SC (2023)	Judicial Affidavit Rule now standard in family courts, shortening trial.
A.M. 02‑11‑10‑SC & 02‑11‑11‑SC (2023 Amendments)	Digital filing & videoconference testimony made permanent; encourages online publication of summons for parties abroad.
House Bill 9349 (Absolute Divorce Bill, passed on 3rd reading March 2024; pending Senate)	No effect yet, but may create a separate “divorce” remedy distinct from annulment & legal separation.

9. Practical Considerations

Item	Typical Range / Notes (Metro Manila)
Filing fees	₱ 10,000 – 15,000 (varies by asset declaration)
Professional fees	₱ 200,000 – 600,000+ (staged payments)
Psychological evaluation	₱ 25,000 – 60,000 per party (if needed)
Duration	1 – 2 years (uncontested, no backlog) to 4 – 6 years (contested/appealed)
Evidence tips	Gather text/email exhibits, financial records, medical reports; secure at least 2 corroborating witnesses; maintain paper trail of support and residence.
Common pitfalls	Collusion; perjured psychological reports; failure to notify OSG; non‑annotation of decree (causes PSA errors).

10. Step‑by‑Step Checklist (Nullity/Annulment)

Consult counsel; determine correct remedy (nullity vs annulment vs legal separation).
Collect evidence early (certified marriage certificate, baptismal records, photos, etc.).
Secure assessments (psychiatric, social worker) where Art. 36 is alleged.
Draft & sign verified petition; include certification of non‑forum shopping.
Pay fees; obtain raffle to Family Court.
Attend pre‑trial & mediation; comply with mandatory parenting seminar.
Present evidence via judicial affidavits; submit Formal Offer.
Await decision; monitor OSG review.
After entry of judgment, file Motion for Entry and secure Certificate of Finality.
Register the decree & CFI with LCRO, PSA, Bureau of Immigration (if remarriage abroad contemplated).

11. Key Take‑Aways

Annulment ≠ Declaration of Nullity: annulment cures a defect in a voidable marriage; nullity says the marriage was void ab initio.
Legal Separation safeguards spouses without severing the marital bond; it is not a stepping stone to remarriage.
The State remains an indispensable party — every petition effectively sues not only the spouse but also the Republic.
Psychological incapacity doctrine is now more humane and case‑specific, but still demands proof of incapacity (not mere marital unhappiness).
Always complete the civil registry annotation; without it, PSA will still issue a “married” status certificate, complicating future transactions.

12. Conclusion

Philippine family law strives to balance the constitutional protection of marriage with compassion for spouses trapped in irretrievably broken unions. Whether you seek a declaration of nullity, annulment, or legal separation, success hinges on choosing the correct remedy, marshaling solid evidence, and navigating procedural nuances. Legislative winds may yet introduce absolute divorce, but for now these traditional remedies—fortified by recent jurisprudence and streamlined court rules—remain the pillars of marital relief in the Philippines.
