Quick answer

Philippine law provides two different court remedies:

Declaration of absolute nullity applies when a marriage was void from the beginning—for example, because an essential legal requirement was absent, the marriage was bigamous or within a prohibited relationship, or a spouse was psychologically incapacitated under Article 36 of the Family Code.
Annulment applies to a marriage that remains valid unless annulled because a specific defect existed when it was celebrated, such as lack of required parental consent, legally defined fraud, force, unsoundness of mind, incurable incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

Separation, abandonment, infidelity, incompatibility, or mutual agreement does not by itself terminate a civil marriage. Even when a marriage is allegedly void, Article 40 generally requires a final court judgment declaring it void before a former spouse may remarry. The judgment, property arrangements when required, and decree must also be properly registered.

Nullity and annulment are not interchangeable

Issue	Declaration of nullity	Annulment
Status of marriage	Void from the beginning	Valid until annulled
Source of grounds	Articles 35–38 and related provisions of the Family Code and special laws	Article 45 of the Family Code
Filing deadline	An action or defense for absolute nullity generally does not prescribe	Strict periods apply, depending on the ground
Can later cohabitation defeat the case?	Generally not by “ratifying” a void marriage, although standing, good faith, and other consequences may matter	Yes, for several grounds, free cohabitation after the defect is removed or discovered bars annulment
Evidence required	Proof of the particular ground; Article 36 requires clear and convincing evidence	Proof of the particular Article 45 ground and timely filing
Effect of the other spouse’s agreement	Agreement is not enough	Agreement is not enough

Neither remedy is the same as:

Legal separation, which may allow spouses to live separately and affects property and inheritance but does not sever the marriage bond;
A church declaration of nullity, which does not by itself change civil status;
Judicial recognition of a foreign divorce, which is a separate proceeding; or
Proceedings under the Code of Muslim Personal Laws, which may be governed by different substantive and jurisdictional rules.

The law in force when the marriage was celebrated can matter, particularly for marriages predating the Family Code’s effectivity on August 3, 1988.

When a marriage may be declared void

Under the Family Code, grounds include the following.

A party was below 18

A marriage involving a party below 18 is void even if parents or guardians consented. Republic Act No. 11596 also declares child marriage void from the beginning and provides that an action or defense concerning its nullity does not prescribe.

The solemnizing officer lacked authority

The marriage is generally void if performed by someone without legal authority. An exception may apply when either or both parties believed in good faith that the officer was authorized.

There was no valid marriage license

A marriage ordinarily requires a valid license. Absence of a license makes the marriage void unless a genuine statutory exemption applied, such as certain marriages in danger of death or a marriage satisfying all requirements for the five-year cohabitation exemption.

The exemption is not established merely by producing an affidavit. Its factual requirements—including the required continuous cohabitation and absence of a legal impediment throughout the relevant period—must actually have existed.

The marriage was bigamous or polygamous

A subsequent marriage contracted while an earlier marriage remained subsisting is generally void. Article 41 contains a narrow exception involving an absent spouse: ordinarily, the spouse present must have a well-founded belief that the absentee is dead, must satisfy the required four-year absence period—or two years in specified danger-of-death circumstances—and must first obtain a judicial declaration of presumptive death.

A person should not remarry based only on prolonged separation, rumors of death, a missing-person report, or a belief that the earlier marriage was void.

There was a mistake about the other party’s identity

This means a genuine mistake as to the person’s identity, not disappointment about character, finances, family background, education, fertility, or social status.

Required registrations following an earlier judgment were not completed

A subsequent marriage may be void under Articles 52 and 53 if the parties remarried without completing the required registration of the earlier judgment, property partition, and delivery of the children’s presumptive legitimes when applicable.

The spouses are within a prohibited relationship

Incestuous marriages between ascendants and descendants or between siblings are void. Article 38 also prohibits specified marriages involving relatives within the fourth civil degree, certain adoptive and affinity relationships, and parties where one killed a spouse to marry the other.

An essential or formal requisite was absent

Articles 2 to 4 address legal capacity, consent freely given in the presence of the solemnizing officer, the officer’s authority, a valid license unless exempt, and the required marriage ceremony. A mere irregularity is not always equivalent to the complete absence of a requisite, so the underlying records and circumstances must be examined carefully.

Psychological incapacity existed at the time of marriage

Article 36 applies when either spouse was psychologically incapacitated, when the marriage was celebrated, to comply with essential marital obligations—even if the incapacity became evident only later.

Psychological incapacity after Tan-Andal

Psychological incapacity is a legal concept, not simply a psychiatric diagnosis and not a general description of an unhappy or failed marriage.

In Tan-Andal v. Andal, the Supreme Court clarified that psychological incapacity must be proved by clear and convincing evidence. The evidence must establish:

Gravity: The condition reflects a genuinely serious psychic cause, not ordinary immaturity, mood changes, occasional outbursts, difficulty, neglect, ill will, or simple refusal to perform marital duties.
Juridical antecedence: The incapacity existed when the marriage was celebrated. Later conduct may reveal it, but evidence must connect that conduct to a durable aspect of personality formed before the marriage.
Legal incurability: The incapacity is enduring and persistent in relation to the particular spouse, such that genuine compliance with essential marital obligations is effectively impossible.

The relevant obligations include living together when legally required, mutual love, respect, fidelity, help and support, family support, household responsibilities, and appropriate obligations toward common children.

A psychologist or psychiatrist is not automatically required, and the allegedly incapacitated spouse need not always be personally examined. Expert evidence can still be useful, but it does not replace credible facts. Courts consider the totality of the evidence, including testimony from people who knew the spouse before and during the marriage, contemporaneous records, and a detailed history of recurring behavior.

Infidelity, addiction, violence, irresponsibility, or abandonment may be relevant evidence in a particular Article 36 case, but none automatically proves psychological incapacity. The evidence must establish the required incapacity, not merely misconduct.

Grounds and deadlines for annulment

Article 45 limits annulment to six grounds that existed when the marriage was celebrated.

Ground	Who may file and deadline	Important limitation
A party was at least 18 but below 21 and married without required parental or guardian consent	The affected party, within five years after turning 21; or the parent, guardian, or person having legal charge, before the party turns 21	Free cohabitation as spouses after turning 21 bars the action
Unsoundness of mind	The sane spouse who did not know of it; a relative, guardian, or person having legal charge of the affected spouse before either party dies; or the affected spouse during a lucid interval or after regaining reason	Free cohabitation after regaining reason may bar the action
Consent obtained through legally defined fraud	The injured party, within five years after discovering the fraud	Free cohabitation with full knowledge of the fraud bars the action
Consent obtained through force, intimidation, or undue influence	The injured party, within five years after the force, intimidation, or influence ceased	Free cohabitation after it ceased bars the action
Physical incapacity to consummate the marriage, continuing and apparently incurable	The injured party, within five years after the marriage	Difficulty, infertility, or refusal is not necessarily the incapacity contemplated by the provision
A serious and apparently incurable sexually transmissible disease	The injured party, within five years after the marriage	The condition must satisfy the statutory requirements and have existed at marriage

“Fraud” has a narrow legal meaning

Article 46 recognizes only specified circumstances:

Non-disclosure of a previous final conviction for a crime involving moral turpitude;
Concealment by the wife that, at the time of marriage, she was pregnant by another man;
Concealment of a sexually transmissible disease existing at marriage; or
Concealment of drug addiction, habitual alcoholism, or—in the Code’s dated wording—homosexuality or lesbianism existing at marriage.

The provision addresses the specified concealment. Sexual orientation by itself is not identified as the ground.

Misrepresentations about character, health outside the statutory categories, rank, fortune, or chastity do not constitute Article 46 fraud. A promise that later proves false is also not automatically fraud existing when the marriage was celebrated.

Because these periods can expire even while spouses are negotiating or living apart, anyone considering annulment should obtain advice well before the apparent deadline.

Who may file

For an ordinary direct petition for declaration of nullity, the special Supreme Court rule states that the petition may be filed solely by the husband or wife. Article 36 may concern the incapacity of either or both spouses; a spouse is not automatically disqualified merely because the petition attributes the incapacity to that petitioner.

Standing is more complicated in bigamous-marriage cases. In Quirit-Figarido v. Figarido, the Supreme Court held that only an aggrieved or injured innocent spouse of either marriage may seek a declaration that the subsequent marriage is void for bigamy. A spouse who knowingly contracted the bigamous marriage may lack standing to use that wrongdoing as a convenient means of becoming free to remarry.

Annulment may be filed only by the persons identified for the applicable ground and within the corresponding period.

If a party dies before entry of judgment, the special rule directs the court to close and terminate the pending marriage case, without prejudice to appropriate estate proceedings. Heirs generally cannot substitute themselves simply to continue a direct nullity or annulment petition.

Where to file

These cases fall within the exclusive original jurisdiction of Family Courts under the Family Courts Act. Where no statutory Family Court exists, a designated Regional Trial Court may handle family cases.

The petition is ordinarily filed in the Family Court of the province or city where either the petitioner or respondent has resided for at least six months before filing. If the respondent is a non-resident, the rule may allow filing where the respondent can be found in the Philippines.

Under the 2023 amendments:

If both parties are abroad for employment, business, education, or another purpose, venue is generally the Philippine habitual residence of either party, at the petitioner’s choice, or the place where they last resided together as spouses.
If only the petitioner is abroad, venue is generally the respondent’s Philippine residence.

Current guidelines require detailed addresses and proof of residence. Depending on the situation, this can include a barangay certification with a location sketch, counsel’s sworn statement, utility bills, identification, lease and rental records, or property documents. Limited documentary exceptions exist for a petitioner abroad or one who left the habitual home for a stated just cause. An affidavit of residence authenticated by the appropriate Philippine consulate may satisfy the requirement for a petitioner temporarily abroad under OCA Circular No. 284-2023.

A false address or fabricated residence document can cause dismissal and expose the party, lawyer, or issuing official to sanctions.

How the court process works

The controlling procedure is the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment, A.M. No. 02-11-10-SC.

1. Identify the correct legal ground

The petition must allege the complete facts supporting a recognized ground. It must also identify the common children, property regime, and properties involved.

For Article 36, the petition should describe concrete manifestations of the alleged incapacity and facts connecting it to the time of marriage. A bare statement that a spouse is “narcissistic,” “toxic,” “immature,” or psychologically incapacitated is insufficient.

2. Prepare and personally verify the petition

The petitioner must personally sign the verification and certification against forum shopping. The case cannot be initiated solely by counsel or an attorney-in-fact.

The special rule states that the petition is filed in six copies and that copies must be served on the Office of the Solicitor General and the city or provincial prosecutor within five days after filing, with proof of service submitted within the same period.

3. Comply with current electronic-filing requirements

Since April 24, 2025, marriage-nullity and annulment cases have been included in Rule 13-A through A.M. No. 25-01-13-SC and OCA Circular No. 116-2025.

An initiatory petition must first be filed personally, by registered mail, or through an accredited courier. The petition and accompanying documents must then be transmitted electronically to the court within 24 hours after completion of the primary filing. Failure to complete the required electronic transmittal can result in the petition being treated as not filed.

Counsel should verify the receiving court’s official email address, PDF requirements, paper-copy instructions, fee assessment, and proof-of-service procedures before filing.

4. Summons is served on the respondent

The respondent ordinarily has 15 days from service to file a verified answer. If the respondent’s location remains unknown despite diligent inquiry, the petitioner may ask the court for permission to serve summons by publication once a week for two consecutive weeks, together with the other measures ordered by the court. The published summons directs the respondent to answer within 30 days from the last publication.

A missing or uncooperative spouse does not make the case automatic.

5. The prosecutor checks for collusion

The respondent cannot be declared in default. If no answer is filed or the answer does not genuinely dispute the case, the court orders the public prosecutor to investigate possible collusion. The prosecutor’s report is ordinarily due within one month after receiving the order.

If the court finds collusion, it may dismiss the petition. If no collusion is found, the case proceeds to mandatory pre-trial.

6. Pre-trial and trial are conducted

The parties generally must appear personally at pre-trial and submit the required pre-trial briefs, evidence, witness affidavits, and proposed stipulations. Mediation may address lawful incidental matters, but the parties cannot compromise the validity of the marriage or invent a ground.

At trial, the petitioner must prove the ground. The court cannot grant the petition solely because:

The respondent admits the allegations;
The respondent does not appear;
Both spouses agree;
The parties submit a stipulated story; or
No one opposes the petition.

No judgment on the pleadings, summary judgment, or confession of judgment is allowed on the ground for nullity or annulment.

7. Decision, finality, and appeal

A decision does not become final immediately. Under the special rule, it generally becomes final after 15 days from notice if no timely motion for reconsideration, motion for new trial, or appeal is filed.

A party seeking to appeal must first file a motion for reconsideration or new trial within 15 days from notice. If that motion is denied, the notice of appeal must generally be filed within 15 days from notice of the denial. The Solicitor General may also appeal.

8. Liquidation, decree, and registration follow

After entry of judgment, the court addresses property liquidation, partition, custody, child support, and delivery of presumptive legitimes when required and not previously adjudicated. The decree is issued after the necessary registrations and property-related requirements are completed.

The prevailing party must cause the decree to be registered with the appropriate local civil registries and the Philippine Statistics Authority and report compliance to the court within 30 days after receiving the decree.

The PSA’s annotation guidance identifies documents commonly needed for an annotated marriage certificate, including the decree, certificate of finality, certificate of registration, certificate of authenticity, and marriage-certificate records.

Do not plan a remarriage based only on an oral ruling, an unsigned decision, a church decree, or an unannotated civil-registry record.

Evidence to preserve

Collect lawful, authentic records early. Depending on the asserted ground, these may include:

PSA marriage and birth certificates;
Certified marriage-license records or a certification that no license record exists;
Marriage-license applications, affidavits supporting an exemption, and the solemnizing officer’s authority;
Records of an earlier marriage, death, annulment, nullity judgment, divorce, or presumptive-death proceeding;
Passports, immigration records, and citizenship documents when foreign nationality or residence matters;
A detailed timeline covering courtship, events before marriage, the wedding, cohabitation, separation, and later manifestations;
Messages, letters, photographs, financial records, police or barangay reports, medical or rehabilitation records, and court records lawfully obtained;
Names and contact details of witnesses with firsthand knowledge, especially people who knew the spouse before the marriage;
Proof of when fraud was discovered or when force, intimidation, or undue influence ended;
Barangay certifications, IDs, leases, bills, and other venue evidence;
Titles, tax declarations, deeds, loan documents, bank records, business records, insurance policies, and lists of debts;
Children’s school, medical, caregiving, and support-expense records; and
Proof of service, court receipts, email transmissions, registry receipts, and publication.

Keep originals secure and make organized copies. Do not access a spouse’s private accounts without authority, alter messages, manufacture diagnoses, coach witnesses to lie, conceal assets, or buy false civil-registry or residence documents.

Children, support, custody, and property

Ending the marriage does not end parental responsibility. The court may issue provisional orders during the case concerning:

Spousal support when legally available;
Custody and support of common children;
Visitation;
Administration of community or conjugal property; and
Other matters requiring urgent action.

The child’s welfare is the controlling consideration in custody arrangements. Support obligations continue regardless of conflict between the parents.

Article 54 preserves the legitimacy of children conceived or born before a judgment annulling the marriage becomes final and of children covered by an Article 36 judgment. Children of a subsequent marriage under Article 53 are also treated as legitimate. The classification of children in other types of void marriages depends on the applicable Family Code provision and facts.

Property treatment is likewise ground-specific. An annulled marriage may involve liquidation under the applicable marital property regime. For a void marriage, Articles 147 or 148 may govern property acquired during cohabitation, depending on whether the parties were legally capacitated to marry each other and whether another marriage subsisted. Title registration alone may not resolve beneficial ownership, contribution, forfeiture, creditor, or good-faith issues.

Common mistakes to avoid

Treating infidelity, abandonment, incompatibility, or failure to provide as automatic grounds for annulment;
Using “irreconcilable differences,” which is not a Philippine annulment or nullity ground;
Assuming a short marriage is easier to annul;
Treating every lie as Article 46 fraud;
Assuming a psychological evaluation guarantees an Article 36 judgment;
Filing in a convenient city using a fictitious address;
Waiting until an annulment deadline has nearly or already expired;
Believing the respondent’s non-appearance guarantees success;
Agreeing with the other spouse to fabricate facts, suppress evidence, or stage an uncontested case;
Paying a fixer or lawyer who promises a guaranteed result;
Hiding children, property, creditors, or a previous marriage;
Assuming a church annulment changes the PSA marriage record;
Remarrying after a favorable decision but before finality, completion of required property steps, issuance and registration of the decree, and verification of the civil-registry annotation; or
Failing to keep copies of the judgment, entry of judgment, decree, registration certificates, and annotated marriage certificate.

Situations requiring prompt legal help

Seek immediate advice if:

An annulment filing period is approaching;
There is a prior or subsequent marriage, possible bigamy, or uncertainty about whether an earlier judgment was registered;
Either spouse obtained a foreign divorce or changed citizenship;
A spouse is missing, abroad, evading service, or using an uncertain address;
A child may be removed, hidden, harmed, or taken abroad;
Property is being sold, transferred, mortgaged, or concealed;
Support has abruptly stopped;
A party is seriously ill or there is a risk of death before entry of judgment; or
You are being threatened, stalked, controlled, or physically harmed.

If anyone is in immediate danger, call Unified 911 or contact the nearest police station. Women and children experiencing covered abuse may also approach the barangay VAW Desk or seek a barangay, temporary, or permanent protection order under Republic Act No. 9262. Safety and protection-order relief need not wait for the marriage case to finish.

Foreign divorce may require a different case

In a qualifying marriage involving a Filipino and a foreign citizen, a valid foreign divorce may be judicially recognized in the Philippines under Article 26. In Republic v. Manalo, the Supreme Court held that the provision can apply regardless of which spouse initiated the foreign divorce, provided the legal requirements are met.

Recognition is not automatic. The party ordinarily must prove the foreign judgment and the applicable foreign law as facts, using properly authenticated or otherwise admissible evidence. Nationality at marriage and divorce, later naturalization, the terms of the decree, and whether the foreign spouse became capable of remarrying can materially affect the case.

Frequently asked questions

Can we obtain an annulment simply because we both agree?

No. The court must receive competent evidence proving a statutory ground. The State, through the prosecutor and Office of the Solicitor General, is involved to prevent collusion and fabricated evidence.

Is adultery or living with another partner a ground for annulment?

Not by itself. Sexual infidelity may support legal separation or other legal remedies and may be relevant evidence in an Article 36 case, but it does not automatically make the marriage void or voidable.

Is a psychologist required for psychological incapacity?

No. Tan-Andal treats psychological incapacity as a legal, not strictly medical, concept. Expert testimony may help, but credible lay testimony and other evidence can establish or defeat the claim.

What if the other spouse refuses to participate?

The case can proceed after valid service and compliance with the special rule, but no default judgment is allowed. The petitioner must still prove the ground, and the prosecutor must protect the State’s interest.

How long does the process take?

There is no guaranteed statutory completion period. Timing depends on service of summons, publication if needed, the prosecutor’s investigation, pre-trial, witness availability, court congestion, property issues, and any appeal. Be cautious of anyone promising a fixed or unusually short completion date.

How much does it cost?

There is no single official total. Costs may include filing and other court fees, service, certified records, publication when required, professional fees, expert services when used, and property registration or annotation expenses. Request a written engagement specifying what the lawyer’s fee includes and which expenses are separate.

Can I remarry as soon as the judge grants the petition?

No. Wait for finality, entry of judgment, completion of property and presumptive-legitime requirements when applicable, issuance and registration of the decree, and confirmation that the civil-registry records have been properly annotated. Obtain case-specific advice before applying for a new marriage license.

What happens to the children?

Custody, support, visitation, and parental authority are determined separately from the spouses’ personal conflict, with the children’s welfare as the primary consideration. The judgment does not erase either parent’s duty to support a child.

Does a church annulment allow civil remarriage?

No. A religious tribunal’s decision may be evidence in an appropriate Article 36 case, but only the proper civil court judgment and completed civil-registration process change civil status under Philippine law.

Does a nullity action have a deadline?

An action or defense for declaration of absolute nullity does not prescribe under Article 39, as amended by Republic Act No. 8533. This does not eliminate standing, venue, proof, registration, or procedural requirements. Annulment actions remain subject to their specific deadlines.
