Quick answer

Annulment and declaration of nullity are different court remedies:

Declaration of absolute nullity applies when the marriage was void from the beginning—for example, because a required marriage license was absent, a party was below 18, the marriage was bigamous, the parties were within prohibited degrees of relationship, or a spouse was psychologically incapacitated under Article 36.
Annulment applies to a marriage that was valid until annulled because a specific defect existed when it was celebrated, such as lack of required parental consent, fraud recognized by law, force, certain forms of incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

Separation, abandonment, infidelity, incompatibility, violence, addiction, or an unhappy marriage does not automatically establish either remedy. Some may support a different case, such as legal separation or protection under laws against violence, or may serve as evidence of psychological incapacity only when the complete facts satisfy Article 36.

A marriage does not end merely because the spouses have separated, signed an agreement, obtained a church annulment, or agreed that the marriage should be dissolved. A Philippine court must grant the proper remedy, the judgment must become final, and the required decree and civil-registry registrations must be completed before either party remarries.

Annulment and declaration of nullity are not interchangeable

A void marriage is legally invalid from the beginning. Nevertheless, Article 40 of the Family Code requires a final judicial judgment declaring the previous marriage void before its nullity may be relied upon for remarriage.

A voidable marriage is considered valid unless and until a court annuls it. The grounds are limited by law, and most are subject to strict filing periods.

Neither remedy is a general form of divorce based simply on events that happened after a valid marriage. The legal ground ordinarily must have existed at the time of the wedding, although the evidence may have become visible later.

The controlling provisions are in the Family Code of the Philippines and the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment.

When a marriage may be declared void

Subject to statutory exceptions and the evidence in a particular case, void marriages include:

A party was below 18

A marriage involving a person below 18 is void even if a parent or guardian consented. Republic Act No. 11596 also expressly provides that a child marriage is void from the beginning and that an action or defense concerning its nullity does not prescribe. The law separately criminalizes specified conduct involving child marriage. See Republic Act No. 11596.

The solemnizing officer lacked authority

The general rule is that a marriage solemnized by someone without legal authority is void. An important exception applies when either or both parties believed in good faith that the officer had authority. The officer’s lack of authority should therefore be verified through official records rather than assumed.

There was no valid marriage license

A marriage celebrated without a required license is generally void. But the Family Code recognizes marriages for which no license is required, including certain marriages in imminent danger of death and qualifying marriages under Article 34.

An expired, fabricated, or nonexistent license is different from a mere irregularity in obtaining an actual license. Obtain a certified record or certification from the relevant local civil registrar before deciding that this ground exists.

The marriage was bigamous or polygamous

A subsequent marriage contracted while a prior marriage was still subsisting is generally void, subject to the carefully defined rules on an absent spouse and judicial declaration of presumptive death under Article 41.

Simply believing that a long-absent spouse has died, or relying on a separation agreement, is not enough. The required judicial proceeding must take place before the subsequent marriage.

In a bigamy situation, standing to bring a nullity case can be especially technical. The Supreme Court has recognized the aggrieved spouse in the prior subsisting marriage as a proper party in appropriate circumstances. Its 2024 decision in Chan-Ceniza v. Ceniza illustrates why the identity and legal position of the petitioner must be assessed before filing.

There was a mistake about the other party’s identity

Article 35 covers a mistake as to the identity of the person married. It does not cover ordinary disappointment or mistaken beliefs about a spouse’s character, wealth, employment, background, or intentions.

The parties were within prohibited degrees of relationship

Incestuous marriages between ascendants and descendants or between full- or half-blood siblings are void. Article 38 also voids specified marriages for public-policy reasons, including certain marriages between relatives up to the fourth civil degree and specified relationships created through adoption or affinity.

The marriage violated Articles 52 and 53

A subsequent marriage can itself be void when a former spouse remarries without completing the registration and related requirements following an earlier judgment of annulment or nullity.

Psychological incapacity existed under Article 36

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

This is not a label for irreconcilable differences, immaturity, infidelity, laziness, refusal to communicate, occasional violence, financial irresponsibility, addiction, or abandonment by itself. The court looks for a serious and enduring psychic cause reflected in a persistent pattern of dysfunction that made the spouse genuinely incapable—not merely unwilling, neglectful, or difficult—of performing essential marital obligations.

Under the Supreme Court’s controlling decision in Tan-Andal v. Andal:

Psychological incapacity is a legal concept, not necessarily a medical illness.
It must be proved by clear and convincing evidence.
It must have existed when the marriage was celebrated, although its manifestations may appear afterward.
It must arise from a durable aspect of the spouse’s personality structure formed before the marriage.
It must be serious and enduring in relation to the particular spouse and marriage.
Expert testimony or a clinical diagnosis is not legally indispensable.

A psychologist or psychiatrist may still be useful when specialized evidence will help explain the person’s history and behavioral pattern. Hiring an expert, however, does not guarantee that Article 36 will be proved. Testimony from people with firsthand knowledge, contemporaneous records, communications, and evidence of conduct before and throughout the marriage may be equally important.

When a marriage may be annulled

Article 45 permits annulment only for the following causes that existed when the marriage was celebrated:

A party was 18 or older but below 21 and married without the required consent of a parent, guardian, or person exercising substitute parental authority.
Either party was of unsound mind, subject to the qualifications in the law.
A party’s consent was obtained through fraud specifically recognized by Article 46.
Consent was obtained through force, intimidation, or undue influence.
Either party was physically incapable of consummating the marriage with the other, and the incapacity continues and appears incurable.
Either party had a serious and apparently incurable sexually transmissible disease.

What counts as fraud

For annulment, “fraud” is not every lie or concealment. Article 46 limits it to:

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

The Family Code expressly states that other deceit about character, health, rank, fortune, or chastity does not constitute this statutory fraud. Particular facts may implicate other laws or remedies, but they do not automatically create a ground for annulment.

Filing deadlines

An action to declare a void marriage absolutely null generally does not prescribe. This does not mean delay is harmless: witnesses may become unavailable, records may be lost, and property or succession issues may become more difficult.

Annulment deadlines depend on the ground:

Ground	Who may file and deadline
No required parental consent	The affected party, within five years after turning 21; or the parent, guardian, or person with legal charge, before that party turns 21
Unsound mind	The sane spouse who lacked knowledge, or a relative, guardian, or person with legal charge of the affected spouse, before either spouse dies; the affected spouse may file during a lucid interval or after regaining sanity
Statutory fraud	The injured party, within five years after discovering the fraud
Force, intimidation, or undue influence	The injured party, within five years after it disappeared or ceased
Incapacity to consummate	The injured party, within five years after the marriage
Serious, apparently incurable sexually transmissible disease	The injured party, within five years after the marriage

For several annulment grounds, freely living together as spouses after the problem has ended or become fully known may prevent annulment. Seek advice promptly rather than assuming the five-year period is always available.

Who may file and where

A petition for declaration of absolute nullity is generally filed by the husband or wife, subject to jurisprudential rules for exceptional situations such as an aggrieved spouse challenging a bigamous subsequent marriage. Annulment may be filed only by the persons and within the periods specified by law.

The case belongs in the Regional Trial Court branch designated as a Family Court. Venue is generally the province or city where either the petitioner or respondent has resided for at least six months immediately before filing. If the respondent is not a Philippine resident, the petitioner may choose the place where the respondent can be found in the Philippines.

Residence must be genuine. Using a temporary or false address to obtain a preferred court can result in dismissal and other consequences.

As of the source-check date below, the Supreme Court has directed electronic filing and service in annulment and nullity cases. Filing mechanics may also require compliance with court-specific instructions and current judiciary rules. Counsel should verify the designated court, approved electronic address or platform, required formats, payment procedure, and whether any physical copies are still required. See the Supreme Court’s electronic-filing announcement.

What the petition and court process involve

The petition must state the complete material facts, not merely repeat the words of the law. It must identify the common children, applicable property regime, and relevant properties. It must be verified by the petitioner personally and accompanied by a certification against forum shopping.

A typical case proceeds through these stages:

Case assessment and evidence collection. Counsel determines whether the facts support nullity, annulment, legal separation, recognition of a foreign judgment, or another remedy.
Preparation and filing. The verified petition and supporting documents are filed in the proper Family Court and served as required on the Office of the Solicitor General and the city or provincial prosecutor.
Summons. The respondent must be properly served. If diligent efforts cannot locate the respondent, the court may authorize service by publication and other required means.
Answer and investigation for collusion. A respondent is not automatically declared in default for failing to answer. Where required, the public prosecutor investigates whether the parties are colluding.
Mandatory pre-trial. The parties generally must appear personally and disclose their proposed evidence and witnesses in accordance with the rules and court orders.
Trial. The petitioner must prove the legal ground. The marriage cannot be invalidated solely because both spouses agree, admit the allegations, or sign a stipulation.
Decision and possible review. The State, through the prosecutor and Office of the Solicitor General, participates to guard against collusion, fabrication, or suppression of evidence. A decision may still be challenged through the remedies and periods allowed by the applicable rules.
Finality, property proceedings, decree, and registration. A favorable trial judgment alone is not the final administrative step.

There is no lawful guaranteed duration or guaranteed result. Service problems, contested evidence, expert testimony, property liquidation, court calendars, post-judgment motions, and appeals can substantially affect the timetable. Be cautious of anyone promising a “sure” result or a fixed completion date through special access to a judge, prosecutor, or court employee.

Provisional support, custody, and protection

While the case is pending, a party may ask the Family Court for provisional orders concerning:

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

The child’s welfare is paramount. A nullity or annulment case should not be used to conceal a child, evade support, dissipate property, or pressure the other parent.

If there is physical violence, sexual violence, stalking, threats, coercive control, or immediate danger to a child or spouse, do not wait for the marriage case. Ask promptly about protection orders, law-enforcement assistance, safe shelter, medical care, and remedies under the Anti-Violence Against Women and Their Children Act or other applicable laws.

Evidence to preserve

The necessary proof depends on the pleaded ground. Preserve original files and reliable copies of:

PSA and local-civil-registry copies of the marriage certificate;
Marriage-license applications, the license itself, and certifications from the issuing civil registrar;
Birth certificates and records relevant to age, identity, or relationship;
Records concerning the authority of the solemnizing officer;
Court decisions, marriage records, and civil-registry annotations involving a prior marriage;
Medical records, with lawful access and appropriate privacy safeguards;
Messages, emails, letters, photographs, recordings, and social-media material in their original form;
Financial records, property titles, tax declarations, bank records, loan papers, insurance policies, and business documents;
Police, barangay, medical, school, rehabilitation, or employment records relevant to the claimed ground;
A dated chronology of important events before and during the marriage;
Names and contact details of witnesses with firsthand knowledge; and
Proof of actual residence for venue purposes.

Do not edit screenshots, coach witnesses, manufacture documents, secretly access an account without authority, or publish intimate evidence online. Preserve metadata where possible and let counsel determine admissibility and privacy issues.

Effects on property, children, and remarriage

A judgment may affect property relations, inheritance rights, donations by reason of marriage, insurance designations, custody, support, and the children’s presumptive legitimes. The precise result depends on the ground, the parties’ good or bad faith, the applicable property regime, existing agreements, creditor rights, and prior court orders.

For a void marriage, property may be governed by Articles 147 or 148 rather than the ordinary rules for a valid marriage. The correct regime is fact-sensitive and should not be assumed from whose name appears on a title.

Children conceived or born before a judgment of annulment becomes final remain legitimate. Article 54 also preserves legitimacy for children conceived or born before a judgment declaring a marriage void under Article 36 becomes final. Other grounds of nullity can produce different consequences for a child’s status, subject to specific statutory protections. A child’s support rights do not disappear because the parents’ marriage is annulled or declared void.

After a favorable judgment becomes final, the applicable requirements may include:

Entry of judgment;
Registration with the civil registry where the marriage was recorded and where the Family Court is located;
Liquidation, partition, and distribution of property where required;
Registration of the approved property partition with the proper Register of Deeds;
Delivery of the common children’s presumptive legitimes where required;
Issuance and registration of the decree; and
Annotation of the marriage record with the local civil registrar and PSA.

The prevailing party must cause registration of the decree as required by the Supreme Court rule and report compliance to the court within 30 days after receiving the decree. The PSA’s annotation guidance identifies documents commonly needed when an annotated Certificate of Marriage has not yet been processed.

Do not remarry merely upon receiving a favorable decision. Confirm that it is final, that the decree has been issued and registered, and that Articles 52 and 53 and all court directives have been satisfied.

Situations requiring a different analysis

A foreign divorce already exists

A foreign divorce does not necessarily require an annulment or Article 36 case. In a qualifying marriage involving a Filipino and a foreign national, the Filipino spouse may seek judicial recognition of a divorce validly obtained abroad that capacitates the foreign spouse to remarry. Philippine courts require proper proof of both the foreign divorce and the relevant foreign law.

Supreme Court jurisprudence has recognized that the identity of the spouse who initiated the foreign divorce is not necessarily controlling. Citizenship at the legally relevant time and the actual effect of the divorce under the foreign spouse’s national law remain important. See Republic v. Manalo and the Court’s later discussion in Republic v. Racho.

A church annulment was granted

A church or canonical decree does not by itself change civil status under Philippine law. It may be considered as evidence in an appropriate civil case, but it does not bind the civil court or authorize remarriage under civil law.

The parties are Muslim

Marriages governed by the Code of Muslim Personal Laws can involve different substantive rules, courts, and forms of divorce. Do not assume that the Family Code procedure described here fully governs a Muslim marriage.

The goal is only to live separately

Legal separation allows qualifying spouses to live separately and may dissolve and liquidate their property regime, but it does not sever the marriage bond and does not permit remarriage. Judicial separation of property, custody, support, protection orders, and criminal or civil remedies may also address particular needs without nullifying or annulling the marriage.

Common mistakes

Treating “annulment” as the name for every attempt to end a marriage.
Choosing psychological incapacity only because it appears more familiar.
Pleading conclusions without detailed, provable facts.
Assuming infidelity, abandonment, violence, addiction, or incompatibility automatically makes a marriage void.
Using the wrong court or an address that does not satisfy the six-month residence rule.
Missing an Article 47 annulment deadline.
Continuing to cohabit freely after discovering fraud or after force or incapacity has ceased without first obtaining advice about the legal effect.
Hiding children, assets, debts, a prior marriage, or pending cases from counsel or the court.
Believing the respondent’s agreement or failure to answer guarantees approval.
Paying a fixer or accepting a promise of a guaranteed judgment.
Remarrying after the decision but before finality, issuance of the decree, and required registrations.
Assuming a PSA marriage record automatically changes as soon as the court signs a decision.

When legal help is urgent

Consult a Philippine family-law practitioner promptly when:

An annulment filing period may be running;
Either spouse is planning to remarry;
A prior or subsequent marriage may be bigamous;
The respondent is abroad, missing, or difficult to serve;
A foreign divorce or foreign nullity judgment exists;
There is threatened sale, transfer, concealment, or dissipation of property;
A child is being withheld, removed from the country, abused, or denied support;
There are threats, violence, stalking, sexual abuse, or coercive control;
A spouse or child needs immediate support or protection;
A party dies while the case is pending; or
A fixer, lawyer, or court contact claims the result can be guaranteed.

People who cannot afford private counsel may ask the Public Attorney’s Office whether they satisfy its indigency and merit requirements. Law-school legal-aid clinics and the Integrated Bar of the Philippines may also be able to identify available assistance.

Frequently asked questions

Can we obtain an annulment if both spouses agree?

Agreement can simplify disputes over permissible collateral matters, but it cannot create a legal ground. The ground must be independently proved, and the prosecutor and the Office of the Solicitor General may participate on behalf of the State.

Can the marriage be ended if my spouse refuses to participate?

A respondent cannot necessarily stop the case by refusing to cooperate. Proper service and proof remain essential, and non-participation does not automatically produce a favorable judgment.

Is a psychological evaluation mandatory?

No. Under Tan-Andal, psychological incapacity is a legal concept and expert opinion is not indispensable. Whether an evaluation would materially strengthen a particular case depends on the available facts and evidence.

Must the allegedly incapacitated spouse be personally examined?

Not necessarily. Courts may consider competent evidence from other sources. The weight of an opinion based only on collateral information will depend on its foundation, consistency, and the totality of the evidence.

Does cheating make a marriage void?

Not by itself. Infidelity may be relevant to legal separation, criminal or protective remedies in appropriate cases, or as one fact within a broader Article 36 pattern. It does not automatically establish psychological incapacity.

Is failure to provide financial support psychological incapacity?

Not automatically. The evidence must show a serious, enduring inability rooted in the spouse’s pre-marital personality structure—not merely refusal, irresponsibility, unemployment, neglect, or a financial dispute.

Is there a standard price or completion time?

No single lawful price or duration applies to every case. Filing and service costs, publication, evidence, professional fees, contested issues, property proceedings, and appeals vary. Request a written engagement agreement and itemized explanation of expected expenses.

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

No. Wait for finality, the required decree, property and presumptive-legitime compliance where applicable, civil-registry registration, and annotation. Obtain legal confirmation that all requirements for remarriage have been completed.

Will the children lose support or inheritance rights?

No. A parent’s duty to support a child does not disappear. Legitimacy, inheritance, custody, property, and presumptive-legitime consequences vary by legal ground and should be addressed expressly in the case.

Can heirs file a nullity case after a spouse dies?

For Family Code marriages, a direct nullity proceeding is generally reserved for the persons authorized by the governing rule and jurisprudence. If a spouse dies before entry of judgment, the pending case is closed, without prejudice to issues that may be raised in the proper estate proceeding. Heirs may challenge marital validity in an estate case when legally appropriate, rather than continue or commence the same kind of direct marital-status action.
