Annulment and Declaration of Nullity of Marriage

Quick answer

In the Philippines, annulment and declaration of nullity of marriage are different legal remedies.

A declaration of absolute nullity applies when the marriage was void from the beginning—for example, because an essential legal requirement was absent, the marriage was bigamous in circumstances not protected by law, the parties were within prohibited degrees of relationship, or a spouse was psychologically incapacitated under Article 36 of the Family Code.

An annulment applies to a marriage that was valid when celebrated but voidable because of a specific defect existing at the time of marriage, such as lack of required parental consent, unsoundness of mind, legally defined fraud, force or intimidation, incurable physical incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

The spouses cannot simply agree that their marriage should be annulled. A court must find and prove a statutory ground. The Family Code expressly requires State participation to prevent collusion and fabricated evidence, and a judgment cannot be based merely on the spouses' agreement or confession. (eLibrary)

As of August 25, 2026, the Philippines has not enacted a general law allowing absolute divorce for ordinary marriages; divorce bills remain legislative proposals rather than existing general law. (Congress of the Philippines)

Annulment and declaration of nullity are not interchangeable

The distinction matters because the grounds, filing periods, evidence, property consequences, and status of children can differ.

A void marriage is legally defective from its inception. Even so, a person who wants to rely on that nullity for purposes of remarriage must obtain a final judicial judgment declaring the previous marriage void. Article 40 of the Family Code does not permit a spouse simply to decide privately that an earlier marriage was invalid. (eLibrary)

A voidable marriage, on the other hand, remains valid and produces legal effects until a court annuls it. Annulment is available only for the grounds specifically recognized by Article 45 and subject to the applicable filing periods and, in several situations, rules on subsequent voluntary cohabitation. (eLibrary)

Legal separation is different from both remedies. It may allow spouses to live separately and may affect property and other marital consequences, but it does not sever the marriage bond or by itself allow either spouse to remarry.

When a marriage may be declared void

Articles 35 to 38 of the Family Code identify several categories of marriages that are void from the beginning. They include, among others:

  • a marriage involving a party below 18 years old;
  • a marriage solemnized by a person without legal authority, unless one or both parties believed in good faith that the solemnizing officer had authority;
  • a marriage without a required marriage license, unless it falls within a statutory exception;
  • certain bigamous or polygamous marriages;
  • a marriage entered into because one party was mistaken about the identity of the other;
  • certain subsequent marriages void under Article 53;
  • a marriage affected by psychological incapacity under Article 36;
  • incestuous marriages between ascendants and descendants or between brothers and sisters, whether of the full or half blood; and
  • marriages prohibited by Article 38 for reasons of public policy, including specified relationships by blood, marriage, or adoption. (Lawphil)

Whether a particular marriage actually falls within one of these categories can depend on documents and facts. For example, merely losing a copy of a marriage license is not the same as proving that no legally required license ever existed.

Psychological incapacity under Article 36

Article 36 provides that a marriage is void when, at the time the marriage was celebrated, either spouse was psychologically incapacitated to comply with the essential marital obligations of marriage, even if the incapacity became evident only later. (eLibrary)

The Supreme Court substantially clarified this doctrine in Tan-Andal v. Andal.

Psychological incapacity is now treated as a legal concept, not necessarily a medical diagnosis. A petitioner does not have to prove that the spouse has a clinically diagnosed mental illness or personality disorder, and testimony from a psychologist or psychiatrist is not indispensable in every case. (eLibrary)

But Article 36 is not simply another term for incompatibility, infidelity, irresponsibility, an unhappy marriage, or refusal to perform marital duties.

The evidence must establish a genuine incapacity rather than mere unwillingness, neglect, difficulty, occasional misconduct, or ordinary personality differences. Current Supreme Court doctrine requires proof of:

  • gravity—the condition must cause a genuine inability to perform essential marital obligations, not merely difficulty or refusal;
  • juridical antecedence—the incapacity must have existed at or before the celebration of the marriage, even if it became obvious only afterward; and
  • incurability in the legal sense—the enduring personality structure must result in persistent inability to comply with marital obligations in relation to the particular spouse.

The petitioner must establish psychological incapacity by clear and convincing evidence, a standard higher than ordinary preponderance of evidence but lower than proof beyond reasonable doubt. (eLibrary)

Is a psychological evaluation required?

Not automatically.

The Supreme Court has expressly ruled that expert testimony is not an indispensable requirement because psychological incapacity is not purely a medical concept. Relatives, friends, household members, colleagues, or other witnesses who knew the spouse before and during the marriage may sometimes provide important evidence of an enduring pattern of behavior. (eLibrary)

An expert evaluation can nevertheless be valuable in an appropriate case, particularly when it helps explain the relationship between longstanding behavior and the spouse's inability to perform essential marital obligations. The usefulness of an expert therefore depends on the evidence available rather than on a mechanical requirement that every Article 36 case have a psychiatric diagnosis.

Grounds for annulment of a voidable marriage

Article 45 recognizes six grounds. The ground must have existed at the time of the marriage.

Lack of required parental consent

A marriage may be annulled when a party was at least 18 but below 21 at the time of marriage and the required parental or substitute parental consent was absent, subject to the statutory rules on who may sue, the filing period, and subsequent voluntary cohabitation after reaching 21. (eLibrary)

Unsoundness of mind

A marriage may be annulled when either party was of unsound mind at the time of marriage, subject to the qualifications in Articles 45 and 47, including the possible effect of freely cohabiting after the affected spouse comes to reason. (eLibrary)

Fraud

Not every lie between spouses constitutes the kind of fraud that permits annulment.

Article 46 specifically identifies the circumstances treated as fraud for this purpose, including:

  • nondisclosure 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 the time of marriage; and
  • concealment of drug addiction, habitual alcoholism, or homosexuality or lesbianism existing at the time of marriage.

These are statutory categories. The Code expressly states that other misrepresentations concerning matters such as character, health, rank, fortune, or chastity do not by themselves constitute Article 46 fraud. (eLibrary)

The statutory reference to homosexuality or lesbianism concerns concealment of the condition existing at the time of marriage as the legislatively specified fraud ground; sexual orientation by itself is not a separate Article 45 ground for annulment.

Force, intimidation, or undue influence

Annulment may be sought where a spouse's consent to the marriage resulted from force, intimidation, or undue influence existing at the time the marriage was celebrated. The law also considers whether the affected spouse voluntarily continued marital cohabitation after the coercion ended. (eLibrary)

Physical incapacity to consummate the marriage

Article 45 covers physical incapacity to consummate the marriage with the other spouse when the incapacity continues and appears incurable. This is different from simply refusing to have sexual relations.

Serious and apparently incurable sexually transmissible disease

A marriage may also be annulled where, at the time of marriage, a spouse was afflicted with a sexually transmissible disease that was serious and appeared incurable. (eLibrary)

Filing deadlines for annulment

Unlike an action to declare a void marriage absolutely null, an annulment action may prescribe.

Article 47 and the Supreme Court's special procedural rule provide different periods depending on the ground:

Ground General filing period
Lack of parental consent By the affected spouse within five years after reaching 21; the qualified parent or guardian may sue before the party reaches 21
Unsoundness of mind Subject to the persons and periods specifically stated in Article 47, generally before the death of either party, or by the affected spouse during a lucid interval or after regaining sanity
Fraud Within five years after discovery of the fraud
Force, intimidation, or undue influence Within five years after it disappears or ceases
Physical incapacity to consummate Within five years after the marriage
Serious and apparently incurable STI Within five years after the marriage

Several grounds may also be lost through the voluntary cohabitation contemplated by Articles 45 and 47 after the defect becomes known or disappears. (Lawphil)

If an annulment ground may apply, delay can therefore be legally significant.

Is there a deadline for declaration of nullity?

Generally, no.

Article 39, as amended by Republic Act No. 8533, provides that an action or defense for the declaration of absolute nullity of marriage does not prescribe. (eLibrary)

That distinction is important: the absence of a prescriptive period for nullity should not be confused with the specific statutory deadlines that apply to annulment.

Where is the case filed?

Family Courts have exclusive original jurisdiction over annulment and declaration-of-nullity cases. In places without a separate Family Court, the designated Regional Trial Court handles cases within Family Court jurisdiction. (Lawphil)

Under A.M. No. 02-11-10-SC, venue is generally in the Family Court of the province or city where either the petitioner or respondent has resided for at least six months immediately before filing. If the respondent is a nonresident, the petitioner may file where the respondent may be found in the Philippines. (Lawphil)

For a petition seeking declaration of absolute nullity under the Family Code, the Supreme Court rule provides that the petition is filed by the husband or wife. (Lawphil)

Current electronic-filing requirements

Court filing practice has changed significantly because of the Judiciary's electronic-filing program.

The Supreme Court amended Rule 13-A in 2025 so that its electronic-filing and service rules expressly cover declaration of nullity and annulment cases. (eLibrary)

Under the current Rule 13-A framework, an initiatory pleading, such as the original petition, remains subject to the permitted primary filing modes under the rule. A PDF copy of the petition and its accompanying documents must then be electronically transmitted to the court within 24 hours after completion of the primary filing. Subsequent covered pleadings and papers are generally filed and served electronically through the required email procedures. (Supreme Court of the Philippines)

Because official court email addresses, technical requirements, and filing arrangements must be followed precisely, counsel or the filer should check the Supreme Court's current Court Locator and electronic-filing instructions for the particular court before submission. (Supreme Court of the Philippines)

What must the petition contain?

The petition must state the complete facts constituting the legal ground, not simply legal conclusions such as "my spouse is psychologically incapacitated."

It must also identify the common children, their ages, the property regime governing the parties, and relevant properties. A petitioner may seek provisional relief regarding matters such as support, custody, visitation, and administration of community or conjugal property when appropriate. (Lawphil)

The petition must be verified and accompanied by a certification against forum shopping personally signed by the petitioner as required by the special rule. The rule also requires service of the petition on the Office of the Solicitor General and the appropriate City or Provincial Prosecutor within five days from filing, together with proof of service to the court within the same period. (Lawphil)

What happens after filing?

The ordinary sequence includes summons, an answer or other response, investigation concerning possible collusion where required, mandatory pre-trial, presentation of evidence, and judgment.

If the respondent does not answer, the court does not simply declare the respondent in default and automatically grant the petition. The public prosecutor may be directed to investigate whether the parties are colluding. (Lawphil)

The Family Code requires the prosecuting attorney to represent the State's interest in preventing collusion and fabricated or suppressed evidence. The validity of the marriage cannot be settled by stipulation or confession of judgment. (Lawphil)

The Supreme Court also clarified in 2026 that spouses' mutual desire to end their marriage, standing alone, does not establish collusion. What the law prohibits is an agreement to fabricate, suppress, or misrepresent facts in order to obtain a decree unlawfully. (Supreme Court of the Philippines)

Evidence worth preserving before filing

The necessary evidence depends on the ground. A useful case file may include:

  • PSA and Local Civil Registrar copies of the marriage certificate and relevant birth certificates;
  • records concerning the marriage license or claimed license exemption;
  • previous marriage certificates, judgments, death certificates, or civil-registry records where a prior marriage is relevant;
  • contemporaneous messages, emails, letters, photographs, diaries, or other communications;
  • medical or treatment records when genuinely relevant and lawfully obtainable;
  • police, barangay, hospital, rehabilitation, employment, school, financial, or similar records that independently corroborate relevant conduct;
  • property titles, tax declarations, deeds, bank records, loan documents, business records, and evidence of ownership or acquisition dates;
  • names and contact details of witnesses who personally observed significant conduct, particularly conduct occurring before or near the beginning of the marriage; and
  • a careful chronology identifying what happened, when it happened, who witnessed it, and what documents corroborate it.

For Article 36 cases, evidence showing only that the relationship eventually deteriorated may be insufficient. The more important question is whether the evidence shows an enduring personality structure, existing before or at marriage, that produced a genuine incapacity to perform essential marital obligations. (eLibrary)

Never manufacture messages, coach witnesses to give false testimony, alter records, or create an artificial psychological history. The court and the State are specifically required to guard against fabricated and suppressed evidence.

What happens to property?

There is no universal rule that every annulment or nullity case results in an automatic 50-50 division.

Property consequences depend on matters such as:

  • whether the marriage is being annulled or declared void;
  • the particular ground of nullity;
  • the parties' marriage settlements;
  • when and how each property was acquired;
  • whether Articles 147 or 148 govern property acquired during a void union;
  • whether either spouse acted in bad faith;
  • existing creditors and encumbrances; and
  • whether property issues were already resolved in another proceeding.

The Family Code provides for liquidation, partition, distribution, and protection of creditors and children's presumptive legitimes in cases where the applicable provisions require them. (Lawphil)

For void marriages, recent Supreme Court jurisprudence has also emphasized that the ordinary property regimes between validly married spouses do not automatically govern; depending on the circumstances, property acquired during the relationship may instead fall under Articles 147 or 148 of the Family Code. (eLibrary)

Because the classification of even one major property can materially affect the result, titles, acquisition dates, source of funds, loan records, inheritance documents, and proof of exclusive contributions should be reviewed early.

What happens to the children?

Annulment or nullity does not erase a parent's obligations toward a child. Custody, parental authority, support, and the child's welfare remain separate legal concerns.

Article 54 specifically provides that children conceived or born before the judgment of annulment, and children conceived or born before a judgment declaring a marriage void under Article 36 becomes final and executory, are considered legitimate. It also contains a special rule for children of a subsequent marriage under Article 53. (Lawphil)

The consequences for children arising from other categories of void marriages may differ. The child's status should therefore be determined from the precise ground for nullity rather than from the general statement that the parents' marriage was declared void.

During the proceedings, the court may issue orders concerning custody, support, visitation, and related urgent matters. (Lawphil)

A favorable decision does not immediately mean you may remarry

This is one of the most important practical points.

A spouse should not remarry merely because a judge has orally indicated how the case will be decided or because a trial-court decision granting the petition has been received.

Under the special rule, a decision generally becomes final after the applicable 15-day period from notice if no proper motion or appeal prevents finality. The rule also requires an aggrieved party who intends to appeal to first file the required motion for reconsideration or new trial within 15 days; the notice of appeal is then governed by the special procedure. (Lawphil)

After finality, the required entry of judgment, liquidation or property proceedings where applicable, issuance of the decree, and civil-registry registrations must be completed. Sections 21 to 23 of A.M. No. 02-11-10-SC prescribe the post-judgment process, including registration of the decree. (Lawphil)

Articles 40, 52, and 53 of the Family Code make these requirements especially important for remarriage. Article 53 states that former spouses may marry again after compliance with Article 52; a subsequent marriage contracted without the required compliance may itself be void. (Lawphil)

Before planning another marriage, obtain and review the final judgment, entry of judgment, decree, and properly annotated civil-registry records, rather than relying only on the original decision.

Common mistakes

Treating adultery, abandonment, or abuse as automatic grounds for annulment

Serious misconduct can be legally significant, but it does not automatically fall within Article 45 or prove Article 36 psychological incapacity. The evidence must establish the elements of an actual statutory ground.

Assuming psychological incapacity means mental illness

It does not. Current Supreme Court doctrine treats psychological incapacity as a legal concept and does not require a psychiatric diagnosis. (eLibrary)

Assuming a psychologist's report automatically proves the case

An expert opinion is evidence, not a guaranteed result. The court examines the totality of evidence and whether it establishes the legally required incapacity by clear and convincing evidence.

Filing an annulment after the statutory period has expired

Annulment grounds have different deadlines. A nullity action generally does not prescribe, but that rule should not be transferred to annulment cases. (eLibrary)

Using "fraud" in its everyday meaning

Article 46 narrowly defines the fraud that supports annulment. Ordinary lies about personality, money, status, or past conduct do not necessarily qualify. (eLibrary)

Assuming an uncontested case is automatically granted

Even if the respondent agrees, fails to answer, or does not oppose the petition, the petitioner must still prove the legal ground. The respondent is not simply declared in default so that the marriage can be ended without evidence. (Lawphil)

Remarrying immediately after receiving the decision

Finality, the decree, civil-registration requirements, and any required property proceedings must first be addressed.

When legal help is urgent

Prompt legal advice is especially important when:

  • an Article 45 annulment deadline may be approaching;
  • either spouse is about to remarry;
  • there is an existing second marriage or possible bigamy issue;
  • one spouse is disposing of, concealing, mortgaging, or transferring substantial property;
  • a child needs immediate support, custody, or protective relief;
  • the respondent is abroad or cannot be located and service may require special procedures;
  • there are foreign marriages, foreign divorces, or conflicting citizenship issues;
  • a spouse has died while the case is pending;
  • the validity of the marriage affects inheritance or an estate proceeding; or
  • the facts potentially support several different grounds and choosing the wrong remedy could jeopardize the case.

Under the special rule, if a party dies before entry of judgment, the nullity or annulment proceeding is generally closed and terminated, without prejudice to appropriate estate proceedings. A death occurring after entry of judgment has different consequences. (Lawphil)

Frequently asked questions

Can spouses jointly agree to an annulment?

They may agree on legally compromisable collateral matters, but they cannot create or stipulate the ground for nullity or annulment. The statutory ground must be independently proved. (Lawphil)

Is infidelity enough for annulment?

Not by itself. Depending on the complete facts, conduct surrounding infidelity may form part of the evidence relevant to another legally recognized ground, including an Article 36 claim, but adultery or infidelity alone is not one of the six Article 45 annulment grounds.

Is abandonment enough for psychological incapacity?

Not automatically. The question is whether the abandonment is part of clear and convincing evidence of a grave and enduring incapacity that existed at or before marriage, rather than simply a later decision or refusal to fulfill marital duties. (eLibrary)

Must the allegedly psychologically incapacitated spouse personally undergo examination?

No categorical rule requires a personal psychological examination in every Article 36 case. Expert evidence itself is not indispensable. The sufficiency of the evidence is assessed from the totality of the case. (eLibrary)

What if my spouse refuses to participate?

Refusal to participate does not necessarily prevent the case from proceeding once valid service and the procedural requirements are satisfied. But nonparticipation also does not mean that the petitioner automatically wins. The ground must still be proved, and the State remains involved in preventing collusion or fabrication. (Lawphil)

Can a declaration of nullity be filed many years after the wedding?

Generally yes. Article 39, as amended by Republic Act No. 8533, states that an action or defense for declaration of absolute nullity does not prescribe. (eLibrary)

Can I remarry as soon as the court grants my petition?

No. Ensure that the judgment has become final and that the required entry, decree, property-related requirements where applicable, and civil-registry registrations have been completed. (Lawphil)
