Quick answer

In Philippine law, “annulment” and “declaration of nullity” are different court cases:

Declaration of nullity applies when the marriage was void from the beginning—for example, because a party was below 18, there was no required marriage license, 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.
Annulment applies to a marriage that was valid until a court annulled it because a specific defect existed at the time of marriage—such as lack of required parental consent, fraud recognized by law, force, certain mental incapacity, incurable physical incapacity to consummate the marriage, or a serious and apparently incurable sexually transmitted disease.

Separation, abandonment, infidelity, incompatibility, violence, addiction, or a spouse’s refusal to cooperate does not automatically annul a marriage. Such conduct may be evidence relevant to a statutory ground, grounds for legal separation or protective relief, or grounds for another case—but the court must decide the marriage case on admissible evidence.

A spouse remains legally married until the proper court judgment becomes final and the required registration and post-judgment steps are completed. Even a marriage believed to be void should not be treated as cleared for remarriage without the final judgment required by Article 40 of the Family Code.

Annulment and declaration of nullity are not interchangeable

Issue	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid until annulled
Source of grounds	Mainly Articles 35–38 and 53 of the Family Code	Article 45
Filing deadline	Generally does not prescribe	Depends on the ground; strict periods apply
Psychological incapacity	A ground for nullity under Article 36	Not an annulment ground
Need for a court case	Yes, particularly to obtain an operative judgment and to remarry lawfully	Yes
Agreement of spouses enough?	No	No

The legal label matters. A petition based on the wrong remedy, unsupported conclusions, or facts that do not fit a statutory ground can be dismissed.

When a marriage may be declared void

Marriages void under Article 35

Subject to the qualifications and exceptions written into the law, Article 35 treats the following marriages as void from the beginning:

A marriage in which either party was below 18, even with parental or guardian consent.
A marriage solemnized by someone without legal authority, unless either or both parties believed in good faith that the solemnizing officer had authority.
A marriage celebrated without a marriage license, unless it falls within a lawful license exemption.
A bigamous or polygamous marriage not covered by Article 41.
A marriage involving a mistake as to the other party’s identity.
A subsequent marriage void under Article 53 because required post-judgment recording and related steps were not completed before remarriage.

The absence of a license must be distinguished from a defective or irregular license. Some marriages are expressly exempt from the license requirement, including qualifying marriages in articulo mortis and qualifying marriages of parties who lived together as spouses for at least five years without a legal impediment to marry. Whether an exemption was valid depends on the actual facts and documents, not merely on what appears in the marriage certificate.

Psychological incapacity under Article 36

Article 36 applies when, at the time of the wedding, one or both spouses were psychologically incapacitated to comply with essential marital obligations, even if the incapacity became evident only later.

Psychological incapacity is not simply:

refusal to perform marital duties;
immaturity or irresponsibility by itself;
ordinary incompatibility;
a difficult personality;
infidelity, abandonment, violence, addiction, or financial irresponsibility standing alone; or
the fact that the marriage has irretrievably broken down.

Under the Supreme Court’s controlling interpretation in Tan-Andal v. Andal, psychological incapacity is a legal concept, not necessarily a medical illness. The evidence must show clear acts of dysfunctionality arising from a genuinely serious psychic cause, rooted in a durable aspect of personality formed before the marriage, which made the spouse incapable—not merely unwilling—to understand and perform essential marital obligations.

The incapacity must be:

serious or grave;
traceable to a condition existing at or before the celebration of marriage, although it may become manifest later; and
enduring or incurable in the legal sense in relation to the particular spouse and marriage.

The petitioner must establish psychological incapacity by clear and convincing evidence. A psychiatric or psychological diagnosis and personal examination of the other spouse are not invariably required. Expert testimony may still be useful, particularly where it reliably connects the spouse’s history and conduct to an incapacity existing when the marriage began. Lay witnesses, records, communications, and other evidence may also be important. The court assesses the totality of the evidence in each case.

Incestuous marriages under Article 37

A marriage is void when it is between:

ascendants and descendants of any degree; or
brothers and sisters, whether of full or half blood.

Marriages void for public-policy reasons under Article 38

Article 38 covers specified relationships, including certain marriages between collateral blood relatives within the fourth civil degree, step-parents and stepchildren, parents-in-law and children-in-law, an adopting parent and adopted child, and certain persons linked through adoption.

It also covers a marriage between parties when one, with the intention to marry the other, killed that other person’s spouse or the killer’s own spouse. Because Article 38 contains a precise statutory list, assumptions about family terminology should be checked against the parties’ actual genealogy and legal relationships.

Bigamous marriages and an absent spouse

As a general rule, a marriage celebrated while a prior marriage remains subsisting is void. Article 41 creates a narrow framework involving a spouse absent for four consecutive years—or two years in specified situations involving danger of death—together with a well-founded belief of death and a court declaration of presumptive death obtained before the subsequent marriage.

Mere disappearance, long separation, lack of communication, or a personal belief that the spouse has died does not by itself authorize remarriage.

When a marriage may be annulled

Article 45 permits annulment only for a cause that existed when the marriage was celebrated.

Lack of required parental consent

This applies when a party was at least 18 but below 21 and married without the required parental or substitute consent. The defect may be ratified if, after turning 21, that party freely lived with the other as spouses.

A marriage involving someone below 18 is different: it is void, not merely voidable.

Unsound mind

Annulment may be available when either party was of unsound mind at the time of marriage. Free cohabitation after the affected spouse came to reason may ratify the marriage.

This ground is distinct from Article 36 psychological incapacity. The correct remedy depends on the nature, timing, and legal effect of the condition proved.

Fraud recognized by the Family Code

For annulment, “fraud” is limited to the circumstances identified in Article 46:

concealment of a previous final conviction for a crime involving moral turpitude;
concealment by the wife that, when the marriage took place, she was pregnant by another man;
concealment of a sexually transmitted disease existing at the time of marriage; or
concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing at the time of marriage.

Other deceit about character, health, social rank, wealth, or chastity is not statutory fraud for annulment. Whether a particular conviction involves moral turpitude is a legal question that should be assessed from the offense and controlling jurisprudence.

Free cohabitation after discovering the fraud can bar annulment on this ground.

Force, intimidation, or undue influence

Consent obtained through force, intimidation, or undue influence can support annulment. If the pressure ends and the injured spouse then freely cohabits with the other as spouses, the marriage may be ratified.

Physical incapacity to consummate the marriage

The incapacity must:

have existed at the time of marriage;
concern consummation with the other spouse;
continue; and
appear incurable.

This is not established merely by lack of intimacy, refusal, infertility, or the inability to have children.

Serious and apparently incurable sexually transmitted disease

The disease must have existed at the time of marriage, be serious, and appear incurable. Medical evidence will ordinarily be important. This ground is distinct from concealment of an existing sexually transmitted disease, which Article 46 classifies as fraud.

Filing deadlines

A declaration-of-nullity action or defense generally does not prescribe. Annulment claims do.

Under Article 47 and the Supreme Court’s special procedural rule:

No parental consent: The affected spouse must file within five years after turning 21. A parent, guardian, or person with legal charge may file before the affected party turns 21.
Unsound mind: The sane spouse who did not know of the condition, a proper relative or guardian, or the affected spouse during a lucid interval or after regaining sanity may file within the periods and subject to the conditions stated in Article 47.
Fraud: The injured spouse must file within five years after discovering the fraud.
Force, intimidation, or undue influence: The injured spouse must file within five years after it ceased.
Physical incapacity to consummate or serious and apparently incurable sexually transmitted disease: The injured spouse must file within five years after the marriage.

Ratification through free cohabitation may defeat several annulment grounds even if the filing period has not expired. Anyone approaching a deadline should obtain legal advice immediately.

Who may file

Under the special rule, a petition for declaration of nullity may generally be filed only by the husband or wife. A petition for annulment may be filed only by the persons authorized for the particular Article 45 ground and within the applicable period.

Standing can become complicated in bigamous marriages, marriages governed by the former Civil Code, estate disputes, and cases involving foreign judgments. In a 2024 ruling, the Supreme Court discussed who may challenge a bigamous marriage and recognized the position of the injured spouse in the prior subsisting marriage. See G.R. No. 259520, November 5, 2024.

Heirs ordinarily cannot simply commence the same direct petition after a spouse’s death under rules applicable to Family Code marriages. They may have different remedies when marital validity arises in a proper estate or property proceeding. The governing law and remedy should be examined carefully.

Where and how the case is filed

The petition is filed in the Family Court—or the designated Regional Trial Court acting as a Family Court—with territorial venue over:

the province or city where the petitioner has resided for at least six months before filing; or
the province or city where the respondent has resided for at least six months before filing.

If the respondent is a nonresident, the petitioner may file where the respondent can be found in the Philippines. Family Courts have exclusive original jurisdiction over these cases under the Family Courts Act of 1997.

Residence allegations should be truthful and supported. Filing in a convenient place where neither party satisfies the residence rule can lead to dismissal.

Since April 24, 2025, annulment and declaration-of-nullity cases have been included in Rule 13-A’s electronic-filing and electronic-service system under A.M. No. 25-01-13-SC. The applicable electronic and conventional filing requirements must both be checked with the proper court. See the Supreme Court’s official announcement.

What the petition must contain

The petition must allege complete, concrete facts constituting the legal ground. It should also identify:

the parties and facts supporting venue;
when and where the marriage was celebrated;
the common children and their ages;
the applicable property regime and relevant properties;
requested orders on custody, support, visitation, and property administration; and
any other relief supported by law.

The petitioner must personally sign the verification and certification against forum shopping. A lawyer or attorney-in-fact cannot sign these solely for the petitioner. A petitioner abroad must comply with the prescribed authentication or current consular and electronic-notarial requirements.

Copies must be furnished to the Office of the Solicitor General and the proper city or provincial prosecutor within the period prescribed by the special rule, with proof submitted to the court. Counsel must reconcile the special rule’s documentary requirements with the current Rule 13-A electronic-filing requirements.

What happens after filing

The usual stages include:

Court review and issuance of summons. The respondent must be formally served. If diligent efforts cannot locate the respondent, the court may authorize publication once a week for two consecutive weeks, together with service at the last known address and any other method the court directs.
Answer. Under the special rule, the respondent generally has 15 days from service, or 30 days from the last publication issue where summons was served by publication. Current procedural rules and the court’s order should be followed.
Investigation for collusion. A respondent’s silence does not produce an automatic victory. The public prosecutor investigates possible collusion when required and represents the State’s interest in preventing fabricated or suppressed evidence.
Social-worker study where appropriate. The court may require a social worker to conduct a case study, particularly when children are involved.
Mandatory pre-trial. The parties identify witnesses, evidence, admissions, issues, and provisional matters. The validity of the marriage cannot be compromised or settled by agreement.
Trial. The petitioner must prove the statutory ground. A confession, admission, agreed statement, or the respondent’s failure to contest the case is insufficient by itself.
Decision and possible post-judgment proceedings. A favorable trial-court decision is not necessarily the last step. A timely motion or appeal may prevent finality.
Registration, property liquidation, and decree. Depending on the case, the entry of judgment, property partition, delivery of children’s presumptive legitimes, and the decree must be registered with the proper civil registries and property registries.

There is no lawful “automatic annulment” because the other spouse did not appear. Nor can spouses privately agree that their marriage is void.

Children, support, custody, and property

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

support for a spouse;
custody and support of common children;
visitation;
administration of community or conjugal property; and
other urgent family matters.

The child’s welfare is paramount. A judgment about the marriage does not eliminate either parent’s duty to support a child.

The effect on a child’s status depends on the ground. Article 54 expressly protects the legitimacy of children conceived or born before the final judgment in an Article 36 case and children covered by Article 53. The Supreme Court has also held that an Article 36 declaration does not strip a legitimated child of legitimate status. See G.R. No. 272006, February 5, 2025.

Property treatment also depends on the ground, the marriage settlements, the parties’ capacity and good faith, and how the property was acquired. A void marriage may be governed by the co-ownership rules in Articles 147 or 148 rather than the ordinary marital-property regimes. Courts must also protect creditors and children’s presumptive legitimes where applicable.

Do not sell, transfer, conceal, mortgage, or withdraw disputed assets merely because a case is contemplated or pending. Such conduct can create separate civil, criminal, evidentiary, and enforcement problems.

When may a former spouse remarry?

Do not remarry upon receiving only:

a trial-court decision;
an unsigned or uncertified copy;
a lawyer’s assurance that the marriage was always void;
a church annulment;
an annotation request that has not been completed; or
proof that the spouses have long been separated.

For remarriage, obtain and verify the final court documents, the entry of judgment, the decree, and the required civil-registry registrations. If property liquidation and delivery of presumptive legitimes are required, those steps must also be completed. Article 53 warns that a later marriage may itself be void if the required recording and related obligations were not completed.

A church decree affects religious status but does not by itself change civil status under Philippine law.

Foreign divorce is a different remedy

A Philippine declaration of nullity or annulment should not automatically be used when a foreign divorce already exists.

Article 26 of the Family Code may allow a Filipino spouse to obtain recognition of a valid foreign divorce that capacitated the foreign spouse to remarry. Supreme Court jurisprudence has also addressed divorces obtained abroad in marriages involving a spouse who was foreign when the divorce was secured. The applicant must ordinarily prove the foreign judgment and the relevant foreign law as facts in a Philippine court proceeding.

Recognition of foreign divorce is procedurally and legally distinct from annulment and declaration of nullity. Citizenship at the relevant times, who obtained the divorce, the foreign decree, and proof of foreign law must be examined.

Evidence to preserve

Preserve originals and reliable copies of:

PSA and local civil-registry marriage certificates;
the marriage-license application, license, exemptions, affidavits, and solemnization records;
birth certificates and adoption or legitimation records of children;
prior marriage records, court judgments, death certificates, and civil-registry annotations;
messages, emails, letters, photographs, recordings, and social-media material lawfully obtained;
medical, treatment, rehabilitation, school, employment, police, barangay, and court records;
proof of residence;
property titles, tax declarations, contracts, bank records, loan documents, insurance policies, and marriage settlements;
records of support, household expenses, remittances, and contributions to property;
a dated chronology of significant events before and during the marriage; and
names and contact details of witnesses with firsthand knowledge.

Do not alter screenshots, coach witnesses, create retrospective messages, impersonate another person, access password-protected accounts without authority, or secretly obtain records in violation of law. Preserve full conversations and metadata where possible, not only favorable excerpts.

For an Article 36 case, evidence from before the wedding and from people who knew the spouse during childhood, adolescence, or early adulthood may be especially important because the alleged incapacity must be traced to a durable pre-marriage aspect of personality.

Practical first steps

Obtain fresh PSA copies of the marriage certificate and relevant birth certificates.
Request the marriage-license record and supporting papers from the local civil registrar where the license was issued.
Prepare a private, factual chronology beginning before the relationship and wedding.
List possible witnesses and what each personally observed.
Inventory assets, debts, children’s needs, pending cases, and safety concerns.
Identify the possible statutory ground without forcing facts into Article 36.
Check the applicable annulment deadline immediately.
Consult a Philippine family-law lawyer and bring the documents—not only a verbal account.
If funds are limited, ask the Public Attorney’s Office whether you meet its current indigency and merit requirements, or inquire about legal-aid services of the Integrated Bar of the Philippines or a qualified law-school legal clinic.
Verify the proper Family Court, its current filing instructions, and Rule 13-A requirements before submission.

Common mistakes

Treating annulment as Philippine “no-fault divorce.”
Assuming years of separation automatically end the marriage.
Using psychological incapacity as a label for ordinary marital fault.
Filing after an Article 47 deadline has expired.
Continuing free marital cohabitation after discovering fraud or after force has ceased without understanding its possible ratifying effect.
Choosing venue based only on convenience.
Assuming the respondent’s consent or nonappearance guarantees approval.
Relying entirely on a psychological report without supporting facts and witnesses.
Presenting only post-wedding conduct without evidence connecting the incapacity to the time of marriage.
Hiding children, property, creditors, prior marriages, foreign cases, or earlier petitions.
Paying a fixer who promises a guaranteed result, a judgment without testimony, or civil-registry alteration without a proper case.
Remarrying before finality, issuance of the decree, and required registration.

When legal help is urgent

Seek prompt legal assistance if:

an annulment deadline may expire soon;
a spouse is threatening, stalking, or committing violence;
a child has been taken, hidden, or placed at risk;
support has abruptly stopped;
property is being concealed or transferred;
a spouse is about to remarry;
a prior marriage or foreign divorce has surfaced;
summons, a subpoena, an order, or a decision has been received;
the respondent lives abroad or cannot be located;
immigration status depends on marital status; or
criminal allegations such as bigamy, falsification, violence, or abuse may be involved.

For immediate danger, contact local emergency services or the appropriate police and barangay authorities. Protection under the Anti-Violence Against Women and Their Children Act and other laws does not require waiting for the marriage case to finish.

Frequently asked questions

Can both spouses simply agree to an annulment?

No. Civil status and marriage validity cannot be compromised. The statutory ground must be proved, and the State participates through the prosecutor and, when appropriate, the Office of the Solicitor General.

Does adultery or abandonment automatically make the marriage void?

No. Those facts may support other legal remedies or contribute to a broader evidentiary picture, but they are not by themselves grounds for nullity under Article 36.

Is a psychologist always required in an Article 36 case?

No. Tan-Andal states that psychological incapacity is a legal concept and expert opinion is not indispensable. Depending on the evidence, a competent expert may nevertheless be highly useful.

Must the psychologist personally examine the other spouse?

Not invariably. The reliability and basis of the opinion matter. The court considers the totality of admissible evidence and gives the opinion only the weight it deserves.

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

Potentially, yes, provided summons is properly served and the petitioner independently proves the ground. The respondent is not automatically declared in default under the special rule.

Is there a fixed cost or completion time?

No reliable nationwide figure or guaranteed duration applies. Cost and timing depend on filing fees, legal representation, expert or publication expenses, service of summons, court schedules, property and custody issues, and appeals. A promised guaranteed result or unusually fast decree is a warning sign.

Will the children become illegitimate?

Not necessarily. Article 54 preserves legitimacy in Article 36 and Article 53 situations, and other rules may apply depending on the ground and the child’s circumstances.

Does a church annulment permit civil remarriage?

No. A church decision may be relevant evidence in an Article 36 case, but it is not binding on the civil court and does not by itself authorize civil remarriage.

Can a marriage certificate simply be cancelled at the civil registry?

Not as a substitute for a direct court action challenging a marriage. The required judgment and decree must first be obtained and properly registered.

Is legal separation the same as annulment?

No. Legal separation may permit spouses to live separately and affect property relations, but it does not dissolve the marriage bond or allow remarriage.
