Quick answer

Annulment and declaration of nullity are different court remedies under Philippine law.

A declaration of absolute nullity applies when the marriage was void from the beginning—for example, because a party was below 18, the marriage was bigamous, the parties were within prohibited degrees of relationship, or a spouse was psychologically incapacitated to perform essential marital obligations when the marriage was celebrated.
An annulment applies to a marriage that was valid until annulled because a specific defect existed at the time of marriage, such as lack of required parental consent, fraud, force, unsoundness of mind, incurable physical incapacity to consummate the marriage, or a serious incurable sexually transmissible disease.

Separation, abandonment, infidelity, incompatibility, or years of living apart do not by themselves make a marriage void or voidable. The legal ground must be proved in court with admissible evidence. Agreement between the spouses is not enough.

A person must not remarry merely because a marriage appears void. For purposes of remarriage, Article 40 of the Family Code requires a final judicial judgment declaring the previous marriage void, followed by the required registration and civil-registry annotation.

Nullity, annulment, and legal separation are not the same

Remedy	Legal character of the marriage	Typical basis	Effect on the marital bond
Declaration of absolute nullity	Void from the beginning	Grounds under Articles 35, 36, 37, 38, 41, 44, or 53 of the Family Code, as applicable	Confirms that no valid marriage existed, subject to legal rules on children, property, and good faith
Annulment	Valid until annulled	Grounds listed in Article 45	Ends the voidable marriage after a final judgment
Legal separation	Marriage remains valid	Grounds under Article 55, generally involving serious misconduct after marriage	Permits separate living and affects property relations, but neither spouse may remarry

These remedies are also different from recognition of a foreign divorce. A foreign-divorce case follows separate substantive and procedural rules and ordinarily requires proof of the foreign judgment and the applicable foreign law.

When a marriage is void from the beginning

The Family Code identifies several kinds of void marriages. The precise provision and its exceptions must be matched to the facts.

Marriages covered by Article 35

Subject to the qualifications in the Code, Article 35 treats the following marriages as void:

A marriage in which either party was below 18, even if a parent or guardian consented.
A marriage solemnized by a person without legal authority, unless either or both parties believed in good faith that the solemnizing officer had authority.
A marriage celebrated without a license, except where the Family Code expressly allows a marriage without one.
A bigamous or polygamous marriage not falling within the limited absent-spouse exception in Article 41.
A marriage in which one party was mistaken about the identity of the other.
A subsequent marriage void under Article 53 because required registration relating to the prior marriage’s judgment, property partition, and children’s presumptive legitimes was not completed.

A missing or irregular document does not automatically prove nullity. The court examines whether a legal requirement was truly absent and whether a statutory exception applies. For example, the Code recognizes certain license-exempt marriages, including qualifying marriages between parties who have lived together as husband and wife for at least five years without a legal impediment to marry each other. A false affidavit of cohabitation does not create the statutory exception.

Psychological incapacity under Article 36

Article 36 covers a spouse who, at the time of marriage, was psychologically incapacitated to comply with the marriage’s essential obligations, even if the incapacity became evident only later.

In Tan-Andal v. Andal, the Supreme Court clarified that psychological incapacity is a legal concept, not necessarily a mental illness or medically diagnosed personality disorder. The evidence must establish:

Gravity: The condition is serious enough to make the spouse genuinely incapable—not merely unwilling, negligent, difficult, immature, or incompatible—of performing essential marital obligations.
Juridical antecedence: The incapacity existed when the marriage was celebrated, although later conduct may reveal it.
Legal incurability: The incapacity is so enduring and persistent in relation to the spouse and the marriage that the marital obligations cannot realistically be performed.

A psychologist or psychiatrist is not automatically required. Nevertheless, psychological records, expert testimony, or a properly supported evaluation may be useful when the facts call for them. The case may also be proved through the totality of credible testimony and documents, including evidence from people who knew the spouse before and during the marriage.

Article 36 is not a general remedy for an unhappy marriage. Infidelity, alcoholism, violence, financial irresponsibility, abandonment, or refusal to communicate may be relevant evidence, but a court must still find that the proven conduct reflects a grave and enduring incapacity rooted in the spouse’s personality structure and existing at the time of marriage. The required proof is clear and convincing evidence.

Incestuous marriages under Article 37

Marriages are void when contracted between:

Ascendants and descendants of any degree; or
Brothers and sisters, whether of the full or half blood.

Marriages void for reasons of public policy under Article 38

Article 38 includes marriages between certain relatives and family-connected persons, such as specified collateral blood relatives, step-parents and stepchildren, parents-in-law and children-in-law, adopting parents and adopted children, and certain parties connected through adoption.

It also covers a marriage between parties when one, with the intention of marrying the other, killed that other party’s spouse or the killer’s own spouse. Because the statutory list is exact, the particular relationship and civil records should be checked rather than assumed.

Bigamous marriages and an absent spouse

A subsequent marriage during an existing marriage is generally void. Article 41 provides a narrow framework when the prior spouse has been absent for the required period and the present spouse has a well-founded belief that the absentee is dead.

Before remarrying under this exception, the present spouse must obtain a summary judicial declaration of presumptive death. Mere absence, inability to contact the spouse, information from relatives, or a personal belief that the spouse has died is not a substitute for the required court proceeding.

The ordinary absence period is four consecutive years. It is reduced to two consecutive years in the danger-of-death circumstances specifically listed in Article 391 of the Civil Code and incorporated by Article 41. Whether the search for the absent spouse was sufficiently diligent is highly fact-dependent.

A second marriage after a nullity judgment

Even after obtaining a judgment declaring a previous marriage void, Articles 52 and 53 may require registration of:

The judgment;
The approved partition and distribution of the spouses’ properties; and
The delivery of the children’s presumptive legitimes.

Failure to complete the applicable requirements can make a subsequent marriage void. Anyone planning to remarry should obtain the final decree and an updated annotated PSA marriage record, and have counsel verify that all registration requirements have been satisfied.

Grounds for annulment of a voidable marriage

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

Lack of required parental consent

This applies when a party was 18 or older but below 21 and married without the consent required by law.

The party who lacked consent may file within five years after reaching 21. The parent or guardian whose consent was required may file before that party turns 21. Voluntary cohabitation after reaching 21, with knowledge of the marriage, can ratify the defect and bar annulment on this ground.

This ground should not be confused with a marriage involving a person below 18, which is void rather than merely voidable.

Unsoundness of mind

Annulment may be available when either party was of unsound mind at the time of marriage, unless the affected person, after regaining reason, freely lived with the other spouse as husband or wife.

The sane spouse who did not know of the condition may generally sue before either spouse dies. A relative or guardian of the person of unsound mind may sue before either spouse dies. The affected spouse may sue during a lucid interval or after regaining sanity.

A diagnosis arising after the wedding is not by itself enough. The evidence must address the party’s mental condition and ability to give valid marital consent at the time of marriage.

Fraud in obtaining consent

Only the kinds of fraud listed in Article 46 support annulment under this ground. They include:

Concealment of a 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 the time of marriage, regardless of its nature; and
Concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing at the time of marriage.

The statute uses classifications and language enacted in 1987; their presence in Article 46 should not be read as a general judgment about a person’s dignity or identity. The legal issue is the statutorily specified concealment existing when consent was given.

No other misrepresentation—including statements about character, health, social standing, wealth, rank, or chastity—automatically constitutes Article 46 fraud.

The injured party must generally file within five years after discovering the fraud. Freely cohabiting after discovery, with full knowledge of the facts, may ratify the marriage and bar the action.

Force, intimidation, or undue influence

The injured party may seek annulment when consent was obtained through force, intimidation, or undue influence, unless that person later freely cohabited with the other spouse after the coercion disappeared.

The petition must generally be filed within five years after the force, intimidation, or undue influence ceased.

Physical incapacity to consummate the marriage

Annulment may be available when either party was physically incapable of consummating the marriage with the other and the incapacity appears incurable.

This is a specific physical condition, not infertility, unwillingness to have children, ordinary sexual disagreement, or psychological incapacity under Article 36. Medical evidence is ordinarily important.

The action must generally be filed within five years after the marriage.

Serious and apparently incurable sexually transmissible disease

A marriage may be annulled when either party had a serious sexually transmissible disease that appeared incurable when the marriage was celebrated.

This differs from Article 46 fraud: concealment of an existing sexually transmissible disease may constitute fraud regardless of the disease’s nature, while the separate Article 45 ground requires a serious and apparently incurable disease.

The action must generally be filed within five years after the marriage.

Filing deadlines: the critical difference

An action or defense seeking a declaration that a marriage is void generally does not prescribe under Article 39. But this does not eliminate evidentiary problems caused by delay, and special questions may arise concerning standing, prior judgments, property, inheritance, or third-party rights.

Annulment deadlines are strict and depend on the ground:

Annulment ground	Who may file	General deadline
No parental consent	Party who lacked consent	Within five years after turning 21
No parental consent	Parent or guardian whose consent was required	Before the affected party turns 21
Unsoundness of mind	Sane spouse without prior knowledge	At any time before either spouse dies
Unsoundness of mind	Relative or guardian of affected spouse	At any time before either spouse dies
Unsoundness of mind	Affected spouse	During a lucid interval or after regaining sanity
Fraud	Injured party	Within five years after discovery
Force, intimidation, or undue influence	Injured party	Within five years after it ceased
Physical incapacity to consummate	Injured party	Within five years after marriage
Serious, apparently incurable STI	Injured party	Within five years after marriage

Ratification through free cohabitation can bar several annulment grounds even when the stated period has not yet expired. Anyone approaching a deadline should seek legal advice immediately.

Who may file

Under the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment:

A petition for declaration of absolute nullity may generally be filed solely by the husband or wife.
An annulment petition may be filed by the injured party, subject to the ground-specific standing and time limits in Article 47.
Compulsory or intestate heirs ordinarily cannot bring the same direct petition after a spouse’s death, although they may raise marriage validity in an appropriate estate proceeding.

Bigamous-marriage cases require special attention. Supreme Court jurisprudence recognizes that the spouse in the prior subsisting marriage may challenge the subsequent bigamous marriage. Standing can depend on which marriage is being attacked and the petitioner’s legal relationship to it; the Supreme Court addressed this issue most recently in Republic v. Almojuela.

Where the case is filed

Family Courts have exclusive original jurisdiction over annulment and declaration-of-nullity cases under the Family Courts Act of 1997.

The petition is filed in the Family Court of the province or city where either the petitioner or respondent has actually resided for at least six months immediately before filing. If the respondent is a nonresident, the petitioner may file where the respondent can be found in the Philippines.

Residence must be genuine. Choosing a court solely for convenience or based on a temporary or fictitious address can result in dismissal and professional consequences. Where no separately organized Family Court exists, a designated Regional Trial Court branch may hear family cases.

What the petition must contain

The petition must be verified and must allege the complete material facts supporting the particular legal ground. It should ordinarily identify:

The parties and their residences;
The date and place of marriage;
The children and their ages;
The parties’ property regime and known properties;
The specific statutory ground and supporting facts;
Relevant prior cases involving the marriage or family;
Proposed arrangements or requested relief concerning support, custody, visitation, and property; and
The facts establishing proper venue.

The pleading must be signed personally by the petitioner. It cannot be based on a bare legal conclusion such as “psychological incapacity” or “fraud.” Deliberately false allegations or fabricated evidence can undermine the case and expose the persons involved to legal and professional liability.

What happens after filing

The usual process includes the following stages, although court orders and case-specific issues may change the sequence:

Review and filing of the verified petition. The court assesses filing requirements, venue, jurisdiction, and payment or exemption from fees.
Service of summons. The respondent must receive lawful notice. Publication may be required if personal service cannot be completed under the rules.
Response or failure to answer. The respondent may contest the petition, but there is no ordinary default judgment simply because no answer is filed.
Collusion investigation. If no answer is filed or the answer does not genuinely dispute the case, the court directs the public prosecutor to investigate possible collusion. The prosecutor represents the State’s interest in preserving marriage and preventing fabricated or suppressed evidence.
Pre-trial. Pre-trial is mandatory. The parties identify issues, witnesses, documents, stipulations, and possible arrangements on matters that the law permits them to settle.
Trial. The petitioner and other witnesses testify and documentary or expert evidence is presented. The respondent and the State may cross-examine witnesses and present contrary evidence.
Decision and post-judgment remedies. A grant or denial does not become final immediately. Under the special rule, an aggrieved party or the Solicitor General must first pursue the prescribed motion for reconsideration before appealing, subject to the applicable 15-day periods stated in the rule.
Finality, liquidation, and decree. If the petition is granted, the court’s entry of judgment, property arrangements, children’s presumptive legitimes where applicable, and registration requirements must be completed before issuance or full effect of the decree.
Civil-registry annotation. The judgment and decree must be registered with the appropriate local civil registrars and the PSA.

There is no lawful guaranteed processing time. Duration depends on service of summons, the court’s calendar, prosecutor participation, disputed evidence, property and child issues, and post-judgment proceedings. A person promising a certain result or an unusually fast “package” should be treated with caution.

Evidence to collect and preserve

Evidence should be obtained lawfully and kept in its original form whenever possible.

Core civil and identity records

PSA marriage certificate;
PSA birth certificates of both spouses and their children;
Marriage license application and supporting records;
Certificate or authority of the solemnizing officer;
Prior marriage records, judgments, entries of judgment, decrees, and death certificates, if relevant;
Local civil-registry certifications concerning the marriage license or registration; and
Proof of actual residence for venue.

Evidence relating to the asserted ground

Depending on the case, preserve:

Messages, emails, letters, photographs, and contemporaneous journal entries;
Medical, psychiatric, rehabilitation, or treatment records lawfully available to the party;
Police, barangay, court, hospital, school, employment, or financial records;
Records showing searches made for an absent spouse;
Proof of relationships, adoption, or a prior subsisting marriage;
Witness names and contact information, especially people with firsthand knowledge from before and during the marriage; and
Financial records concerning property, debts, income, support, and the children’s needs.

Do not edit screenshots, coach witnesses, obtain records through unauthorized access, or create documents after the fact and present them as contemporaneous. Preserve complete conversation threads, metadata, original files, devices, and backup copies when possible.

Children, custody, and support

A nullity or annulment case does not erase parental duties.

While the case is pending, the court may issue provisional orders concerning:

Support for spouses and children;
Custody and visitation;
Administration of common property; and
Protection of the children’s welfare.

The child’s best interests remain the controlling consideration in custody matters. A parent should not withhold necessary support merely because parentage, custody, or the marriage is disputed.

Children conceived or born before a final annulment judgment are generally legitimate. Article 54 also expressly preserves the legitimacy of children conceived or born of marriages declared void under Article 36 or Article 53. Other nullity grounds can have different consequences for civil status, although the child retains rights granted by law, including support and inheritance rights applicable to the child’s legal status.

The effect on a particular child’s surname, birth record, legitimacy, or inheritance should be reviewed from the judgment, the applicable nullity ground, and the child’s records—not assumed from the fact that a case was granted.

Property consequences

The result depends on the marriage’s validity, each party’s good or bad faith, the applicable property regime, and the existence of children and third-party creditors.

Possible issues include:

Inventory, liquidation, and partition of community or conjugal property;
Return or forfeiture of certain shares where bad faith is proved;
Delivery of children’s presumptive legitimes;
Revocation of certain donations by reason of marriage;
Rights of innocent purchasers, lenders, and other creditors; and
Ownership rules for property acquired by parties to a void union under Articles 147 or 148.

Title registration is not always conclusive of beneficial ownership between the parties. Preserve deeds, titles, tax declarations, loan documents, receipts, bank statements, business records, and proof of each party’s contributions.

Do not sell, mortgage, transfer, conceal, or dissipate disputed assets to defeat the other spouse or the children. Urgent provisional relief may be available if property is at risk.

Registration and PSA annotation

A favorable trial-court decision alone is not the final document needed to prove freedom to remarry.

The special Supreme Court rule requires registration of the entry of judgment and, where applicable, the approved property partition and delivery of the children’s presumptive legitimes before the decree is issued. The prevailing party must then cause registration of the decree with the required civil registries and report compliance to the court within 30 days from receiving the decree.

If summons was served by publication, the decree must also be published once in a newspaper of general circulation.

After registration, verify that the Local Civil Registry Office forwarded the supporting documents to the PSA. The PSA’s guidance on annotation recommends checking with the local civil registrar where the marriage was registered when a newly issued marriage certificate does not yet carry the annotation.

Before remarrying, obtain and review:

The final decision;
The entry of judgment or certificate of finality;
The court-issued decree;
Proof of registration with the required civil registries;
The registered property documents, if applicable; and
A newly issued PSA marriage certificate bearing the correct annotation.

Common mistakes to avoid

Treating separation as automatic nullity

Years of separation do not dissolve a marriage. Neither does a private agreement declaring the parties “single.”

Using “annulment” as a label for every case

The correct remedy depends on whether the marriage was void from the beginning or merely voidable. Pleading the wrong statutory ground can cause dismissal.

Assuming misconduct automatically proves psychological incapacity

Bad behavior may be evidence, but Article 36 requires proof of a grave, antecedent, and legally incurable incapacity—not simply fault or unwillingness.

Relying only on the other spouse’s admission

The court cannot grant the case solely on a confession of judgment, an agreed statement of facts, or the spouses’ mutual desire to end the marriage. The State participates, and the legal ground must be independently proved.

Inventing an address to obtain a preferred court

The six-month residence requirement is a real venue rule. Evidence of actual residence may be examined.

Using a fixer or buying a “guaranteed decree”

Only a court can grant these remedies. Verify the lawyer’s standing through the Supreme Court’s official lawyer-listing resources and insist on official receipts, copies of filed pleadings, docket details, and court-issued documents.

Remarrying before finality and registration

A pending case, an oral announcement in court, or even a signed decision is not enough. Remarrying prematurely can create another void marriage and possible criminal exposure.

Ignoring children and property until after trial

Custody, support, property liquidation, creditor claims, and presumptive legitimes can materially affect the case and the issuance of the decree.

When legal help is urgent

Consult a Philippine family-law lawyer promptly if:

An annulment deadline may expire soon;
A spouse is preparing to remarry or has entered another marriage;
Children have been taken, hidden, threatened, or denied necessary support;
Property is being sold, mortgaged, transferred, or concealed;
Summons, a court order, or a prosecutor’s notice has been received;
The respondent lives abroad or cannot be located;
A party or child faces violence, stalking, coercion, or threats;
Immigration, inheritance, retirement benefits, insurance, or a pending estate depends on marital status; or
A prior foreign divorce, foreign marriage, adoption, or presumptive-death order is involved.

Where abuse is present, safety should come first. Annulment or nullity is not the only possible remedy. Protection orders and criminal or civil relief may be available under the Anti-Violence Against Women and Their Children Act and other laws. Contact emergency services, the nearest police Women and Children Protection Desk, or a trusted lawyer or support organization when immediate protection is needed.

People who cannot afford private counsel may ask the Public Attorney’s Office about legal assistance, subject to its applicable qualification and merit requirements. Local IBP legal-aid offices and law-school legal clinics may also be able to assist.

Frequently asked questions

Can both spouses simply agree to an annulment?

No. They may agree on lawful arrangements concerning property, support, or children, subject to court approval, but they cannot create a ground for annulment or nullity. The court must receive sufficient evidence and the public prosecutor must guard against collusion.

Can the case proceed if the other spouse refuses to participate?

Potentially, yes. Refusal to cooperate does not give the respondent a permanent veto, but lawful service of summons, the collusion investigation, trial, and proof of the legal ground remain necessary. There is no automatic default judgment.

Is a psychological evaluation mandatory in an Article 36 case?

No. Under Tan-Andal, psychological incapacity is a legal—not exclusively medical—concept, and expert testimony is not indispensable in every case. Whether an evaluation is strategically necessary depends on the available evidence and the theory of the case.

Is infidelity a ground for annulment?

Not by itself. Infidelity may support legal separation or other remedies, and its surrounding facts may be relevant in an Article 36 case. It does not automatically establish psychological incapacity or Article 46 fraud.

Is abandonment a ground for nullity?

Not by itself. Later abandonment may be evidence of a condition that existed at the time of marriage, but the petitioner must connect it to a recognized legal ground.

Can a marriage be annulled because the spouses never had children?

No. Infertility is not the same as incurable physical incapacity to consummate the marriage. Concealment or related facts may require separate analysis, but childlessness alone is not a ground.

Is a church annulment enough to remarry civilly?

No. A religious declaration affects the parties under the rules of the religious body but does not change Philippine civil status. A civil court judgment and the required registrations are necessary.

Can a void marriage simply be ignored?

Not safely. Although a void marriage is void from the beginning, Article 40 requires a final judicial declaration of nullity before either party contracts another marriage. A court judgment may also be essential for property, inheritance, benefits, and civil-registry records.

How long does the case take and how much does it cost?

Philippine law provides no single guaranteed duration or fixed total cost. Expenses vary with filing and service requirements, publication, transcripts, professional fees, expert evidence, property issues, location, and appeals. Ask for a written engagement agreement and itemized estimates; distrust guaranteed outcomes or guaranteed completion dates.

Can the court deny the petition even if the respondent agrees?

Yes. The petitioner bears the required burden of proof. The court must deny the petition if the evidence does not establish a statutory ground.

Can a person remarry immediately after winning?

No. The judgment must become final, and the entry of judgment, decree, registration, property-related requirements, and civil-registry annotation must be completed as applicable. Have counsel verify the documents before obtaining another marriage license.
