Quick answer

Annulment and declaration of nullity are different court remedies:

Declaration of absolute nullity applies when the marriage was legally void from the beginning.
Annulment applies when the marriage was valid until a court annulled it because a specific defect existed when it was celebrated.

Neither remedy is available simply because spouses are incompatible, separated, unhappy, abandoned, or unfaithful. The petitioner must prove a ground recognized by law. Even an “uncontested” case requires evidence, participation by the State, trial, a final judgment, registration, and a court decree. Spouses cannot end their civil marriage through a private agreement, barangay settlement, church annulment, or PSA correction alone.

A void marriage generally requires a final judicial declaration before either party may remarry. Do not schedule or enter another marriage based only on a favorable trial-court decision; complete finality, registration, property and children-related requirements, and obtain the registered decree and properly annotated civil-registry records first. These rules appear principally in the Family Code and the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment.

Nullity and annulment are not interchangeable

Issue	Declaration of nullity	Annulment
Status of marriage	Void from the beginning	Valid until annulled by final judgment
Grounds	Absence of essential or formal requisites, psychological incapacity, prohibited relationships, bigamy and other grounds for void marriages	Only the grounds in Article 45 of the Family Code
Filing deadline	An action or defense for absolute nullity does not prescribe	Strict deadlines apply, depending on the ground
Effect of later cohabitation	Generally cannot validate a void marriage	Free cohabitation after the defect ends or becomes known may bar certain grounds
Evidence	Must prove the specific cause of nullity	Must prove the ground, timeliness and absence of legal ratification

The date and circumstances of the marriage matter. Marriages governed by older law, Muslim marriages governed by the Code of Muslim Personal Laws, foreign marriages, and cases involving foreign divorce require a separate legal assessment.

When a marriage is void from the beginning

A declaration of nullity may be appropriate when an essential or formal requisite of marriage was absent—not merely irregular—or when the marriage falls under a statutory prohibition.

Absence of an essential or formal requisite

The essential requisites are legal capacity and consent freely given in the presence of the solemnizing officer. Formal requisites include the solemnizing officer’s authority, a valid marriage license unless an exception applies, and a marriage ceremony in which the parties personally declare that they take each other as spouses before the officer and at least two adult witnesses.

Absence may make the marriage void. A mere irregularity generally does not, although the person responsible may incur civil, criminal or administrative liability.

Grounds expressly listed in the Family Code

Void marriages include:

A marriage in which either party was below 18, even with parental consent.
A marriage solemnized by someone without legal authority, unless either or both parties believed in good faith that the person had authority.
A marriage without a valid marriage license, unless it falls within a lawful license exemption.
A bigamous or polygamous marriage not protected by Article 41.
A marriage contracted because one party mistook the identity of the other.
A subsequent marriage void under Article 53 because required judgment, property and civil-registry formalities from an earlier annulment or nullity case were not completed.
A marriage affected by psychological incapacity under Article 36.
An incestuous marriage between ascendants and descendants of any degree or between full- or half-blood siblings.
A marriage prohibited for public policy reasons, including specified marriages between relatives by blood up to the fourth civil degree, step-relations, certain in-law and adoptive relations, and a marriage involving a person who killed a spouse with the intention of marrying the other party.
In appropriate circumstances, a subsequent marriage in which both parties acted in bad faith.

Republic Act No. 11596 additionally declares a child marriage void from the beginning, and the action or defense does not prescribe. The law applies notwithstanding cultural or customary practices. See the Supreme Court E-Library text of the Prohibition of Child Marriage Law.

Important exceptions involving marriage licenses and prior spouses

“No marriage license” is not automatically a winning ground. The Family Code recognizes license exemptions, including certain marriages at the point of death, qualifying marriages in remote places, marriages performed under specified Muslim or ethnic cultural customs, and marriages of parties who had lived together as spouses for at least five years without any legal impediment throughout the required period.

For an alleged five-year-cohabitation exemption, a false affidavit does not cure the absence of a license. Evidence commonly includes the marriage certificate, the alleged license number, records from the local civil registrar that supposedly issued it, and a properly worded certification concerning the absence of a license record.

Likewise, a prior spouse’s disappearance does not by itself permit remarriage. Article 41 ordinarily requires four consecutive years of absence—or two years in specified circumstances involving danger of death—a well-founded belief that the absentee is dead, and a judicial declaration of presumptive death obtained before the later marriage.

Psychological incapacity under Article 36

Psychological incapacity is a legal concept, not a shortcut for incompatibility or a medical label for a difficult spouse.

Under the Supreme Court’s controlling decision in Tan-Andal v. Andal, the petitioner must prove by clear and convincing evidence that:

The spouse’s durable or enduring personality structure caused clear acts of dysfunctionality.
The condition made the spouse genuinely unable—not merely unwilling, neglectful or difficult—to understand and comply with essential marital obligations.
The incapacity existed when the marriage was celebrated, even if it became clearly visible only later.
It was grave and enduring in relation to the particular marital relationship.

Essential obligations include living together, mutual love, respect and fidelity, help and support, and the spouses’ obligations toward their children.

A psychiatrist or psychologist is not legally indispensable. Ordinary witnesses who knew the spouse before and during the marriage may establish consistent behavior and the environment in which the personality structure developed. Expert evidence may still be useful, depending on the case, but a report based on conclusions unsupported by credible facts will not cure weak evidence.

Infidelity, abandonment, violence, drug use, alcoholism or financial irresponsibility does not automatically establish psychological incapacity. Such conduct may support an Article 36 case only when reliable evidence links it to a serious, enduring incapacity that existed at the time of marriage. Some of the same conduct may instead support legal separation, a protection order, a criminal complaint, or another remedy.

Either spouse may generally bring an Article 36 petition, including the spouse alleged to be psychologically incapacitated, subject to the rules on legal standing.

Grounds and deadlines for annulment

Every annulment ground must have existed when the marriage was celebrated.

Ground	Who may file	Deadline and qualification
Party was 18 or older but below 21 and married without required parental or guardian consent	The affected party; or the parent, guardian or person with legal charge	Affected party: within five years after turning 21. Parent or guardian: before the party turns 21. Free cohabitation after age 21 may bar the action.
Unsound mind	The sane spouse who did not know of the condition; specified relatives, guardian or person with legal charge; or the affected spouse	Depending on the filer, before either spouse dies, during a lucid interval, or after sanity is regained. Free cohabitation after regaining reason may bar relief.
Consent obtained through statutory fraud	Injured party	Within five years after discovering the fraud. Free cohabitation with full knowledge may bar the action.
Force, intimidation or undue influence	Injured party	Within five years after it disappeared or ceased. Free cohabitation afterward may bar the action.
Continuing and apparently incurable physical incapacity to consummate the marriage with the other spouse	Injured party	Within five years after the marriage
Serious and apparently incurable sexually transmissible disease	Injured party	Within five years after the marriage

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

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

The statutory ground is the concealment, not sexual orientation by itself. Other misrepresentations about character, health, rank, wealth or chastity do not constitute Article 46 fraud.

Because annulment deadlines can expire, obtain legal advice promptly rather than waiting for reconciliation efforts or informal negotiations to end.

Who may file

The general procedural rule states that a direct petition for declaration of nullity may be filed solely by the husband or wife. Annulment may be filed only by the persons specified for the particular ground and within the applicable period.

Standing becomes more complicated in bigamous marriages. In Quirit-Figarido v. Figarido, the Supreme Court held that the aggrieved or injured innocent spouse of either marriage may seek nullity of the subsequent bigamous marriage; an erring spouse who knowingly contracted the bigamous marriage may lack capacity to bring that petition.

If a spouse dies before entry of judgment, the pending nullity or annulment case is generally closed and terminated. The marriage’s validity may still be determined when essential to an estate, heirship or other proper proceeding, but that is not the same as continuing the matrimonial petition.

Where and how the case is filed

The petition is filed in the Family Court of the province or city where either spouse 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 petition must:

State the complete material facts—not conclusions or a generic “irreconcilable differences” allegation.
Identify the common children and their ages.
State the governing property regime and identify the properties involved.
Be verified personally by the petitioner.
Include a personally signed certification against forum shopping.
Follow the special rule’s copy, service and authentication requirements.

The special rule calls for service of a copy on the Office of the Solicitor General and the city or provincial prosecutor within five days after filing, with proof submitted to the court within the same period. Noncompliance may result in dismissal.

Current electronic-filing requirement

Since April 24, 2025, nullity and annulment cases have been included in mandatory electronic filing and service under Rule 13-A through A.M. No. 25-01-13-SC.

For an initiatory petition, electronic transmission does not simply replace every paper-filing requirement. Under the interim rule, the primary filing is made personally, by registered mail or by accredited courier, followed by electronic transmittal of the petition and accompanying documents within 24 hours. Failure to complete the required electronic transmittal can cause the petition to be treated as not filed. Counsel should verify the current email address and technical directions of the proper court before filing.

What happens after filing

Summons is served. The respondent ordinarily has 15 days from service to file a personally verified answer. If court-authorized publication is necessary, publication is made once a week for two consecutive weeks and the answer is due within 30 days from the last publication.
There is no automatic default judgment. If the respondent does not answer, the court does not simply grant the petition. The grounds still have to be proved.
The prosecutor checks for collusion. If no answer is filed or the answer raises no real issue, the court directs the public prosecutor to investigate. The prosecutor ordinarily submits a report within one month from receiving the order. A finding of collusion can lead to dismissal.
Pre-trial is mandatory. The parties normally must appear personally and submit compliant pre-trial briefs. Failure by the petitioner to appear can result in dismissal unless a valid excuse is properly established.
Some side issues may be mediated, but marital status cannot be compromised. Spouses may address lawful issues involving property, custody, visitation or support, but cannot agree that a marriage is void or that an annulment ground exists.
Trial is conducted by the judge. The petitioner must present admissible testimony and documents. A confession, stipulation, the respondent’s silence or the parties’ agreement cannot substitute for proof.
The court decides the petition and related matters. Where necessary, the decision addresses property liquidation, custody, support and the children’s presumptive legitimes.
Post-judgment work is completed. If no proper motion or appeal is filed, the decision ordinarily becomes final 15 days after notice. An appeal generally requires a motion for reconsideration or new trial within 15 days from notice, followed—if denied—by a notice of appeal within 15 days from notice of denial.
Registration and decree follow. The entry of judgment must be registered with the civil registries where required. Property partition must be registered with the proper Registry of Deeds, and applicable presumptive legitimes must be delivered before issuance of the decree. The prevailing party must cause registration of the decree and report compliance to the court within 30 days after receiving it.

The procedural rules do not guarantee a fixed completion time. Service problems, publication, court congestion, prosecutor review, witness availability, property disputes and appeals can materially extend the case.

Evidence to collect and preserve

Start with records that establish the marriage and the exact legal ground:

PSA and local civil-registry copies of the marriage certificate.
Birth certificates of both spouses and all children.
Marriage-license application, alleged license number, registry entries and any certification from the proper local civil registrar.
Records concerning the solemnizing officer’s authority and the ceremony.
Certificates and judgments involving prior marriages, annulment, nullity, death, presumptive death or foreign divorce.
Documents proving age, identity, citizenship, adoption or prohibited family relationship.
For psychological incapacity, a detailed chronology of conduct before and during the marriage, witnesses with personal knowledge, and lawfully obtained medical, treatment, financial, school, employment or incident records.
For fraud, force or intimidation, contemporaneous messages, letters, reports, witness accounts and other records showing what happened, when it was discovered or when the pressure ceased.
For medical grounds, properly obtained medical evidence addressing the condition at the time of marriage, seriousness, continuity and apparent incurability.
Titles, tax declarations, loan papers, bank and investment records, business documents, insurance policies and proof of each spouse’s contributions.
Children’s school, medical and living-expense records, caregiving history and existing support arrangements.

Keep originals safely, create backed-up copies and preserve dates and metadata. Do not alter screenshots, coach witnesses, fabricate documents, access a spouse’s protected account, or obtain private medical or financial information unlawfully.

Temporary orders while the case is pending

If there is no adequate written arrangement, 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.
Other matters requiring urgent action.

Annulment or nullity does not suspend parental duties. Child support, safety and welfare remain separate responsibilities while the case is pending and after judgment.

Effects on children and property

A judgment does not erase parenthood.

Children conceived or born before a judgment of annulment becomes final remain legitimate. The Family Code also specifically preserves the legitimacy of children conceived or born before the finality of a declaration under Article 36 and children covered by Article 53. The status of children from other void marriages depends on the precise ground and facts, so it should not be assumed that every nullity judgment produces the same result.

Property consequences also differ:

An annulled marriage ordinarily involves liquidation of the applicable community or conjugal regime.
Property acquired during a void marriage may be governed by the special co-ownership rules in Articles 147 or 148.
Good or bad faith, title, actual contribution, an existing marriage settlement, creditors and the ground for nullity can change the result.
Applicable forfeitures, donations, insurance designations and inheritance consequences must be addressed separately.

Do not transfer, hide, mortgage or dispose of disputed property to defeat the other spouse or the children. Seek an urgent provisional order if assets are at risk.

Common mistakes

Treating “annulment” as the general name for every way of ending a marriage.
Assuming infidelity, abandonment, abuse or years of separation automatically create an annulment ground.
Inventing psychological symptoms or relying on a template evaluation without credible supporting facts.
Believing a cooperative respondent guarantees approval.
Concealing the respondent’s real address to obtain publication.
Using only a PSA “no record” result to conclude that no marriage exists; local registration, delayed registration and other proof may matter.
Confusing a missing marriage-license number with conclusive proof that no license was issued.
Ignoring statutory license exceptions.
Missing an annulment deadline while negotiating privately.
Filing in a convenient city without satisfying the six-month residence rule.
Remarrying after a favorable decision but before finality, registration and the decree.
Assuming a church annulment changes civil status.
Omitting property, creditors or children from the petition.
Paying anyone who promises a guaranteed judgment, a “package annulment,” fabricated evidence or a fixed outcome.

When legal help is urgent

Seek immediate help when:

An annulment deadline may be close.
You have received summons, a decision or an order with a short response period.
A spouse is threatening to take a child, leave the country with the child, sell property, drain accounts or destroy evidence.
A spouse has died or is critically ill while a case is pending.
The facts involve bigamy, falsified civil records, child marriage or possible criminal liability.
You plan to remarry and are unsure whether all prior judgments and registrations are complete.
There is violence, stalking, coercion or a threat to you or a child.

Annulment is not an emergency-protection remedy. Call 911 or contact the police when danger is immediate. For violence against women or their children, Republic Act No. 9262 provides barangay, temporary and permanent protection orders. A barangay protection order is generally effective for 15 days; a court-issued temporary protection order is generally effective for 30 days pending the hearing for a permanent order. See the official Anti-VAWC law and Philippine Commission on Women guidance.

People who cannot afford private counsel may ask the Public Attorney’s Office for assessment under its current indigency and merit rules. Eligibility is determined by PAO and requires supporting documents.

Frequently asked questions

Do both spouses have to agree?

No. One qualified petitioner may file. But agreement or non-opposition does not prove the ground, and collusion can result in dismissal.

What if the respondent refuses to sign or cannot be found?

The respondent’s consent is unnecessary. The court must still obtain proper service. If diligent efforts fail, court-authorized publication and service at the last known address may be used.

Is a psychologist required for psychological incapacity?

Not as a matter of law. Tan-Andal allows proof through the totality of credible evidence, including ordinary witnesses. Expert evidence may still be useful in a particular case.

Is cheating enough for annulment or nullity?

Not by itself. Infidelity may support legal separation or another remedy. For Article 36, it must be connected by clear and convincing evidence to a serious, enduring psychological incapacity existing when the marriage was celebrated.

Can spouses obtain annulment through a notarized agreement?

No. Civil status and the validity of marriage cannot be privately compromised. Only a court can grant nullity or annulment.

Can I remarry immediately after receiving a favorable decision?

No. Confirm finality, entry of judgment, liquidation and presumptive-legitime requirements where applicable, registration of the judgment and decree, and annotation of civil-registry records. Obtain legal confirmation before remarrying.

Does a church annulment end the civil marriage?

No. A church decision may be offered as persuasive evidence in an Article 36 case, but it does not bind the civil court or by itself change PSA records.

What if there is a foreign divorce?

Judicial recognition of foreign divorce is a distinct proceeding. Article 26 may apply when a valid foreign divorce capacitates the foreign spouse to remarry, including certain marriages in which one spouse became a foreign citizen before the divorce. The foreign divorce and the relevant foreign law must be properly pleaded and proved. See Republic v. Ng.

Do these rules apply to Muslim marriages?

Not necessarily. Marriages governed by Presidential Decree No. 1083 may involve different substantive rules and Shari’a court jurisdiction. Seek counsel familiar with Muslim personal law.

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

There is no legally fixed total cost or guaranteed duration. Expenses may include filing and sheriff’s fees, publication, certified records, transcripts, registration, counsel and—if genuinely useful—expert services. Ask for a written engagement agreement and an itemized estimate based on the actual ground, venue, evidence, property and expected service issues.
