Quick answer

In Philippine law, annulment and declaration of nullity are different court remedies:

Annulment applies to a marriage that was valid when celebrated but is voidable because of a ground listed in Article 45 of the Family Code.
Declaration of absolute nullity applies to a marriage that was void from the beginning, including a marriage affected by psychological incapacity under Article 36.

Separation, abandonment, infidelity, incompatibility, or a spouse’s agreement to end the marriage does not by itself cancel the marriage. A Family Court must receive evidence, apply a statutory ground, and issue a final judgment. Even an uncontested case is not automatic because the State, through the public prosecutor and the Office of the Solicitor General, is tasked with guarding against collusion and fabricated evidence.

This discussion primarily covers civil marriages governed by the Family Code of the Philippines. Muslim marriages and divorces may instead be governed by the Code of Muslim Personal Laws. Marriages celebrated before the Family Code took effect on August 3, 1988 may also require analysis under earlier law.

Annulment versus declaration of nullity

Issue	Annulment	Declaration of nullity
Status of marriage	Valid until annulled by final judgment	Void from the beginning, although a judicial declaration is generally necessary to establish status and is required before remarriage
Main legal basis	Article 45	Articles 35, 36, 37, 38 and 53, among others
Filing deadline	Depends on the ground; statutory periods apply	The action or defense does not prescribe under Article 39, as amended by Republic Act No. 8533
Proof required	Facts establishing a specific Article 45 ground	Facts establishing the particular reason the marriage was void
Agreement of spouses enough?	No	No

Calling every case an “annulment” can lead to the wrong ground, evidence, deadline, or property consequences. The marriage certificate, dates, ages, prior marriages, license records, citizenship history, and facts existing at the time of the wedding should be reviewed before choosing a remedy.

When a marriage may be void from the beginning

Absence of an essential or formal requirement

Subject to statutory exceptions, Article 35 treats the following marriages as void:

Either party was below 18 years old, even if a parent consented.
The solemnizing officer lacked authority, unless either or both parties believed in good faith that the officer had authority.
There was no marriage license, unless the marriage fell within a lawful license exemption.
The marriage was bigamous or polygamous, except for a subsequent marriage contracted under the strict presumptive-death provisions of Article 41.
There was a mistake as to the identity of the other party.
A subsequent marriage was contracted without the compliance required by Article 53.

A missing PSA record does not necessarily prove that there was no marriage license or no valid marriage. The original records of the local civil registrar, the license application, certifications from the proper record custodian, and the circumstances of the ceremony may be decisive.

Psychological incapacity under Article 36

Psychological incapacity is a legal concept, not simply a psychiatric diagnosis. Under the Supreme Court’s en banc ruling in Tan-Andal v. Andal, it means a genuine inability—not merely refusal, neglect, immaturity, incompatibility, or difficulty—to understand and perform essential marital obligations because of a serious psychic cause.

The evidence must establish, clearly and convincingly, that the incapacity:

Existed when the marriage was celebrated, although it may have become obvious only later;
Came from a durable or enduring aspect of the spouse’s personality structure;
Was grave enough to make genuine compliance with essential marital obligations impossible; and
Was incurable in the legal sense—enduring and persistent in relation to the particular spouse and marital union.

Essential obligations include living together, observing mutual love, respect and fidelity, providing mutual help and support, and performing parental responsibilities where children are involved.

A psychologist or psychiatrist is not legally required in every Article 36 case. Relatives, friends, household members, colleagues, or other witnesses who personally observed enduring behavior before and during the marriage may provide important evidence. An expert may still assist, but a diagnosis or a report based on unsupported conclusions does not automatically prove the case. The Supreme Court reaffirmed this evidence-based approach in Soto v. Reyes-Soto.

Adultery, abandonment, substance use, violence, financial irresponsibility, or repeated dishonesty may be relevant manifestations, but none is automatically psychological incapacity. The court considers the total pattern, its roots, its seriousness, and its connection to the inability to perform marital obligations.

Incestuous marriages

Article 37 declares marriages void between:

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

Marriages void for reasons of public policy

Article 38 includes, among others, marriages between certain collateral blood relatives up to the fourth civil degree, specified step-relations and in-law relations, an adopter and adoptee, certain persons connected through adoption, and parties where one killed the other’s spouse or their own spouse to marry the survivor.

The precise family relationship and documentary proof of filiation must be examined. Informal family labels such as “cousin,” “stepchild,” or “adopted child” are not enough to determine the legal result.

Prior marriage and remarriage

A person who believes an earlier marriage was void should not simply remarry. Article 40 requires a final judicial declaration of nullity of the previous marriage for purposes of remarriage. Presumptive death under Article 41 is also a judicial process with demanding factual requirements; long separation alone does not automatically authorize another marriage.

When a marriage may be annulled

Article 45 provides an exclusive set of grounds for annulment:

Lack of required parental consent

One party was 18 or older but below 21 and married without the required consent of a parent, guardian, or person having substitute parental authority.

The party may file within five years after reaching 21. A parent, guardian, or person with legal charge may file before the party reaches 21. The ground may be lost if, after reaching 21, the spouses freely lived together as spouses.

Unsound mind

Either party was of unsound mind when the marriage was celebrated, unless that party later regained reason and freely cohabited with the other spouse.

The sane spouse who did not know of the condition may generally file at any time before either spouse dies. A relative, guardian, or person having legal charge of the affected spouse may file during that spouse’s lifetime. The affected spouse may file during a lucid interval or after regaining sanity.

Fraud in obtaining consent

The injured party must file within five years after discovering the fraud. Article 46 limits actionable fraud to:

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

Other misrepresentations concerning character, health, social standing, wealth, rank, or chastity do not constitute Article 46 fraud. Cohabiting freely after learning the truth may also bar annulment on this ground.

Force, intimidation, or undue influence

Consent was obtained through force, intimidation, or undue influence. The injured party must file within five years from the time the force, intimidation, or undue influence disappeared or ceased. Freely cohabiting after it ended may bar the action.

Physical incapacity to consummate the marriage

One party was physically incapable of consummating the marriage, the incapacity continued, and it appeared incurable. The injured party must file within five years from the celebration of the marriage.

This ground concerns physical incapacity, not a spouse’s mere refusal or loss of interest.

Serious and apparently incurable sexually transmissible disease

One party had a serious sexually transmissible disease that appeared incurable. The injured party must file within five years from the celebration of the marriage.

This ground is distinct from fraudulent concealment of an existing sexually transmissible disease. The allegations, medical evidence, and applicable filing period must match the ground actually invoked.

Who may file

For Family Code marriages governed by the special procedural rule, the petition generally must be filed by the aggrieved or injured husband or wife. Heirs, children, creditors, and unrelated third parties ordinarily cannot file the special petition in place of a spouse. A spouse whose own bad faith created the defect may face a standing problem, particularly in a knowingly bigamous union.

Older marriages and proceedings may be governed by different rules. The Supreme Court’s current discussion of standing appears in Quirit-Figarido v. Figarido. Because standing can depend on the wedding date, applicable law, ground, and petitioner’s good or bad faith, it should be assessed before filing.

Where and how the case is filed

The petition is filed 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, venue may be where the respondent can be found in the Philippines, at the petitioner’s election.

The verified petition must set out the specific ground and supporting facts, not simply statutory labels. It normally identifies the spouses, children, property regime, assets, liabilities, previous cases, and requested orders concerning support, custody, visitation, property, and children’s presumptive legitimes. The petitioner must personally sign the required verification and certification against forum shopping.

Copies must be furnished to the proper public prosecutor and the Office of the Solicitor General within the period required by the special rule. Lawyers must also comply with the Supreme Court’s current electronic-filing requirements. Rule 13-A was extended to annulment and nullity cases in 2025, although the initiatory petition must still be lodged in the manner required by the proper trial court. Counsel should verify the current submission instructions of the relevant Office of the Clerk of Court. The Supreme Court maintains an official electronic-filing information page.

What happens after filing

A typical case includes the following stages:

Review by the clerk and issuance of summons. The respondent must be served. If the respondent’s location is genuinely unknown despite diligent efforts, court-authorized alternative service or publication may be necessary.
Answer or failure to answer. The case is not won merely because the respondent does not answer or appear. Default procedures used in ordinary civil cases do not eliminate the need to prove the marriage ground.
Investigation for collusion. The court directs the public prosecutor to investigate whether the spouses fabricated evidence, suppressed material facts, or secretly agreed to manufacture a ground.
Temporary orders where needed. During the case, the court may address support between spouses, custody and support of common children, and appropriate visitation when the parties have no adequate written arrangement.
Pre-trial and trial. The petitioner must present admissible documents and witnesses. The respondent may contest the evidence, while the prosecutor represents the State’s interest in preventing collusion and fabricated proof.
Decision and post-judgment remedies. A party generally must file a motion for reconsideration or new trial within 15 days from notice before appealing under the special rule. If that motion is denied, the notice-of-appeal period is also generally 15 days from notice of denial. These deadlines are strict and should be calculated by counsel from the actual dates and modes of service.
Finality, registration, and decree. A favorable ruling is not the end of the administrative process. The entry of judgment must be registered with the appropriate civil registries. Where applicable, the approved property partition must be registered and the children’s presumptive legitimes delivered before the decree is issued.

Court proceedings and records involving family matters receive confidentiality protections under the Family Courts Act, subject to the judge’s authority and applicable rules.

Property, children, and support

A judgment changing marital status does not automatically settle every financial or parenting issue.

Property

The governing rules depend on the ground, the date of marriage, any valid marriage settlement, the spouses’ good or bad faith, and how property was acquired. A valid marriage may involve absolute community or conjugal partnership rules. A void union may instead be governed by the special co-ownership rules in Articles 147 or 148.

Do not assume that every asset will be divided equally or that a title in only one spouse’s name conclusively determines ownership. Contributions, source of funds, inheritance, donations, debts, bad faith, and the applicable property regime may matter.

Children

Annulment or nullity does not erase parentage or the duty to support a child. Custody is determined according to the child’s best interests, with appropriate support and visitation orders.

Children conceived or born before a judgment of nullity under Article 36 becomes final remain legitimate under Article 54. Article 54 also protects children of a subsequent marriage covered by Article 53. The status of children in other void marriages may be different and must be determined from the specific ground and dates.

Remarriage

Do not remarry based only on an oral ruling, an unsigned decision, or a decision that has not become final. Before obtaining a new marriage license, confirm that:

The judgment is final and executory;
The entry of judgment and required decree have been issued;
Required civil-registry annotations and registrations are complete;
Property and presumptive-legitime requirements, where applicable, have been satisfied; and
The PSA record accurately reflects the court action.

Failure to complete the legally required steps can affect the validity of a later marriage and create serious civil or criminal complications.

Evidence to preserve

Gather records lawfully and keep unedited originals whenever possible:

PSA marriage certificate and advisory on marriages;
Birth certificates of the spouses and children;
Marriage-license application and records from the local civil registrar;
Prior marriage certificates, judgments, death certificates, or presumptive-death records;
Documents establishing residence and proper venue;
A dated chronology covering courtship, the wedding, and married life;
Messages, emails, letters, photographs, and contemporaneous journals;
Police, barangay, medical, counseling, or social-work records, where legally obtainable;
Names and contact details of witnesses with personal knowledge;
Property titles, tax declarations, deeds, bank and loan records, business records, and proof of contributions;
Income records and documentation of household and children’s expenses;
School and medical records relevant to custody or support; and
For a foreign divorce, the complete foreign decree or official record and competent proof of the relevant foreign law.

Avoid secretly accessing password-protected accounts, altering screenshots, coaching witnesses, or posting sensitive evidence online. Preserve full conversations and metadata where possible; isolated screenshots can be challenged as incomplete or unauthenticated.

Common mistakes

Choosing psychological incapacity merely because it appears more flexible than another ground.
Treating infidelity, abandonment, abuse, or incompatibility as automatic grounds for nullity.
Filing an annulment after the applicable five-year period has expired.
Alleging “fraud” that is not one of the limited forms recognized by Article 46.
Assuming a spouse’s nonappearance guarantees approval.
Using a template containing general accusations without dates, witnesses, or supporting facts.
Inventing or exaggerating facts to make a case fit a legal ground.
Confusing absence of a PSA record with absence of a marriage license.
Hiding children, property, debts, prior cases, or a prior marriage.
Believing that a psychologist’s diagnosis alone proves Article 36.
Remarrying before finality, registration, and issuance of the required decree.
Agreeing privately on property or custody without checking whether court approval or registration is required.

When legal help is urgent

Consult a Philippine family-law lawyer promptly if:

An annulment deadline may be running;
Either spouse intends to remarry;
There is a disputed prior marriage or questionable marriage license;
A spouse has disappeared or lives abroad;
The respondent is evading service;
Property is being sold, transferred, hidden, or heavily encumbered;
A child has been taken, concealed, denied support, or threatened with removal from the country;
Foreign citizenship, a foreign marriage, or a foreign divorce is involved; or
Court papers, summons, or an adverse decision have already been received.

If cost is a barrier, ask the Public Attorney’s Office whether the applicant meets its indigency and merit requirements, or inquire with an IBP legal-aid office or law-school legal-aid clinic.

Where there is violence or an immediate threat, personal safety comes first. Annulment or nullity is not an emergency protection remedy. Contact the nearest police station or Women and Children Protection Desk, the barangay VAW Desk, or the local social-welfare office. A qualified applicant may seek a Barangay, Temporary, or Permanent Protection Order under Republic Act No. 9262 without waiting for the marriage case to finish.

Other remedies may fit better

Legal separation allows spouses to live separately and addresses property consequences but does not dissolve the marriage or permit remarriage.
Protection orders, criminal complaints, custody, and support proceedings may provide faster relief for violence, threats, child-safety concerns, or financial abandonment.
Judicial recognition of a foreign divorce may be the proper remedy when a valid foreign divorce capacitated a foreign spouse to remarry. The foreign divorce and the relevant foreign law must be proved in Philippine court. The Supreme Court has held that recognition is not defeated merely because the Filipino spouse initiated the foreign divorce in a covered situation; see Republic v. Manalo.
Correction of civil-registry entries cannot ordinarily substitute for a proper case determining marital status.

Frequently asked questions

Can spouses obtain annulment simply because both agree?

No. Civil status cannot be ended by private agreement. The petitioner must prove a statutory ground, and the prosecutor must investigate possible collusion.

Is adultery or abandonment a ground for annulment?

Not by itself. It may support legal separation, protection, support, or other remedies and may be evidence relevant to psychological incapacity, but only if the complete Article 36 standard is proved.

Is a psychological evaluation mandatory?

No. Tan-Andal holds that expert testimony is not indispensable. A lawyer may still recommend an evaluation when it can responsibly explain an enduring personality structure and connect reliable evidence to the legal requirements.

How long does the case take?

There is no lawful guaranteed completion time. Duration depends on service of summons, the court’s docket, contested issues, prosecutor participation, number of witnesses, expert evidence, postponements, appeals, property proceedings, and civil-registry compliance. Be cautious of anyone promising a guaranteed result or completion date.

How much does it cost?

There is no universal lawful package price. Court fees depend partly on the relief and property issues; legal fees, publication or service expenses, document costs, and any expert fees vary. Request a written engagement agreement and an itemized estimate. No lawyer can ethically guarantee that a petition will be granted.

Can a person remarry immediately after winning?

No. Wait for finality, entry of judgment, the required decree, registration and annotations, and compliance with applicable property and children’s presumptive-legitime requirements.

Can heirs file after a spouse dies?

Generally, the special petition for a Family Code marriage belongs to the aggrieved or injured spouse. Questions involving an older marriage, inheritance, or a collateral challenge may follow different substantive and procedural rules, so heirs should obtain case-specific advice rather than filing a standard nullity petition.

Does a foreign divorce automatically update Philippine records?

No. It normally must first be judicially recognized in the Philippines, with competent proof of the divorce and foreign law, before the civil registry and PSA records can be properly annotated.
