Quick answer

Philippine law provides two distinct remedies:

Declaration of absolute nullity applies when the marriage was legally void from the beginning—for example, because of bigamy, absence of a required marriage license, prohibited relationship, or psychological incapacity under Article 36.
Annulment applies when the marriage was valid when celebrated but voidable because of a specific defect existing at that time, such as lack of required parental consent, fraud, force, unsoundness of mind, incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

A failed or unhappy marriage is not, by itself, a legal ground. Separation, incompatibility, infidelity, abandonment, violence, or refusal to provide support may have other legal consequences, but the person asking the court to end the marital bond must prove a ground expressly recognized by law.

Even a marriage considered void from the beginning requires a final court judgment before either party may remarry. A favorable trial-court decision alone is not enough: finality, the court decree, property and children-related requirements where applicable, and civil-registry registration must be completed.

Nullity and annulment are not interchangeable

Question	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid until annulled by final judgment
Main legal basis	Articles 4, 35–40 and related provisions of the Family Code	Articles 45–47 of the Family Code
Filing period	The action or defense generally does not prescribe	Strict periods apply, depending on the ground
Effect of later voluntary cohabitation	Does not ordinarily make a void marriage valid	Can bar annulment on several grounds
Proof required	Facts establishing a statutory ground for nullity	Facts establishing a statutory ground for annulment existing when the marriage was celebrated

These remedies are also different from:

Legal separation, which may allow spouses to live separately and may dissolve their property regime, but does not sever the marriage bond or permit remarriage.
A church annulment, which affects religious status but does not by itself alter civil status.
Recognition of a foreign divorce, which is a separate proceeding governed by Article 26 of the Family Code and jurisprudence. A foreign divorce is not automatically effective in Philippine civil records; the foreign judgment and the applicable foreign law generally must be proved in court.
Divorce under the Code of Muslim Personal Laws, which follows a separate legal framework when applicable.

Grounds for declaring a marriage void

Under the Family Code of the Philippines, marriages that may be void from the beginning include:

A marriage involving a party below 18 years old, even if a parent or guardian consented.
A marriage solemnized by someone without legal authority, unless either or both parties believed in good faith that the solemnizing officer had authority.
A marriage without a required marriage license, unless it falls within a valid statutory exemption. Whether an exemption truly applied is document- and fact-specific.
A bigamous or polygamous marriage, except a subsequent marriage validly contracted under the rules on presumptive death. Simply believing that a missing spouse has died is not enough for remarriage; Article 41 generally requires the prescribed judicial declaration of presumptive death beforehand.
Mistake about the other party’s identity. This means a mistake as to who the person actually is, not disappointment about the person’s character, finances, background, or behavior.
A subsequent marriage void under Article 53 because the former spouses did not complete the recording and related requirements imposed after an earlier annulment or declaration of nullity.
Incestuous marriages, including marriages between ascendants and descendants or between full- or half-blood siblings.
Marriages prohibited for reasons of public policy, including specified relationships between certain relatives by blood, adoption, and affinity, and the situation in which one party killed a spouse to marry the other.
Psychological incapacity under Article 36.

Other cases may involve absence of an essential or formal requisite of marriage. The exact records and the law in force when the marriage was celebrated must be examined. For example, the absence of a PSA marriage certificate, by itself, does not necessarily prove that no marriage ceremony occurred or that the marriage was void.

An action or defense for absolute nullity does not prescribe under Republic Act No. 8533. Delay can still make witnesses, records, and other evidence harder to obtain.

What psychological incapacity means today

Psychological incapacity is not a general label for a difficult, irresponsible, abusive, unfaithful, or incompatible spouse. It is a legal concept concerning an enduring inability to perform essential marital obligations—not merely a refusal, neglect, difficulty, ill will, occasional outburst, or ordinary character flaw.

Under the Supreme Court’s en banc ruling in Tan-Andal v. Andal, G.R. No. 196359, May 11, 2021, the evidence must establish:

Gravity: The problem is serious enough to show a genuine incapacity to perform essential marital obligations, rather than ordinary marital difficulty.
Juridical antecedence: The incapacity existed, in all reasonable likelihood, when the marriage was celebrated, although its manifestations may have become apparent only later.
Legal incurability: The enduring personality structures of the spouses are so incompatible or antagonistic, relative to their marriage, that the incapacity persists and the union’s breakdown is inevitable and irreparable. Medical incurability is not required.
A connection to essential marital obligations: The proven condition must explain the person’s inability to live as a present, loving, faithful, respectful, and supportive spouse or to perform other obligations imposed by family law.
Clear and convincing evidence: This is a higher standard than ordinary preponderance of evidence, although lower than proof beyond reasonable doubt.

A psychiatric or psychological diagnosis is not legally indispensable. The allegedly incapacitated spouse does not always need to undergo a personal examination. Testimony from relatives, friends, and others who knew the person before and during the marriage may be important, as the Supreme Court reaffirmed in its official discussion of Green v. Green.

An expert can still be useful when the history is complicated or expert analysis will help connect conduct, personality structure, antecedence, gravity, and marital obligations. An evaluation should not be treated as a purchased certificate guaranteeing nullity. The court decides from the totality of admissible evidence.

Grounds and deadlines for annulment

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

Ground	Who may generally file and deadline	Important qualification
A party was 18 or older but below 21 and married without required parental or guardian consent	The affected party, within five years after turning 21; or the parent, guardian, or person with legal charge before the party turns 21	Freely living together as spouses after the affected party turns 21 may ratify the marriage
Unsoundness of mind	The sane spouse who did not know of it; a relative, guardian, or person with legal charge, before either party’s death; or the affected spouse during a lucid interval or after regaining reason	Free cohabitation after regaining reason may bar annulment
Consent obtained by statutory fraud	The injured party, within five years after discovering the fraud	Free cohabitation with full knowledge of the fraud may bar the case
Force, intimidation, or undue influence	The injured party, within five years after it ceased	Free cohabitation after it ceased may bar the case
Continuing and apparently incurable physical incapacity to consummate the marriage with the other spouse	The injured party, within five years after the marriage	The incapacity must satisfy the statutory requirements
Serious and apparently incurable sexually transmissible disease	The injured party, within five years after the marriage	This is distinct from concealment of any existing sexually transmissible disease as statutory fraud

For annulment, “fraud” is narrowly defined. Article 46 lists:

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

The statute’s sexual-orientation provision concerns concealment as the alleged fraud; sexual orientation alone is not stated as an annulment ground. Other lies about character, health, rank, wealth, or chastity do not constitute Article 46 fraud.

Because prescription and possible ratification can defeat an otherwise valid annulment claim, urgent legal assessment is important.

Who may file

The special procedural rule states that a nullity petition may be filed by a spouse. Annulment standing depends on the particular ground and Article 47.

Standing is not always as simple as saying that either spouse may file. In Quirit-Figarido v. Figarido, G.R. No. 259520, November 5, 2024, the Supreme Court held that a spouse who knowingly contracted a bigamous marriage could not use that wrongdoing to seek nullity of the subsequent marriage; only an injured or innocent spouse of either marriage had standing in that situation. A lawyer should therefore examine the particular ground, the petitioner’s participation or good faith, and the controlling decisions.

After a spouse dies, relatives or heirs ordinarily cannot commence the same direct marital-status petition as though they were the spouse. Questions about a marriage’s validity may instead arise in an estate or another proper proceeding, depending on the facts.

Where and how the case is filed

Family Courts have exclusive original jurisdiction over these cases under the Family Courts Act of 1997. The petition is filed in the Family Court of the province or city where either spouse has actually resided for at least six months immediately before filing. If the respondent is not a Philippine resident, the petitioner may file where the respondent can be found in the Philippines.

Residence must be genuine. Using a temporary or fabricated address to obtain a preferred court can lead to dismissal and professional or legal consequences.

The petition must:

allege the complete material facts, not merely repeat the words of the statute;
identify the common children and their ages;
state the applicable property regime and identify the properties involved;
be personally verified by the petitioner;
include the petitioner’s certification against forum shopping; and
address appropriate relief for custody, visitation, support, property administration, and other urgent matters when needed.

The verification and certification cannot simply be signed by counsel or an attorney-in-fact. A petitioner abroad must comply with the applicable execution, notarization or consular requirements.

Since April 24, 2025, nullity and annulment cases have been included in Rule 13-A on electronic filing and service under A.M. No. 25-01-13-SC. The initiatory petition is filed through the permitted paper mode—personal filing, registered mail, or accredited courier—and its PDF copy and accompanying documents must generally be emailed to the court within 24 hours after completion of that primary filing. Later pleadings and service are generally electronic unless another mode is prescribed. Counsel should confirm the branch’s official email address and current technical instructions.

Under the special rule, the petitioner must also serve the petition on the Office of the Solicitor General and the appropriate city or provincial prosecutor within five days from filing and submit proof of service within the same period. Noncompliance may cause dismissal.

What happens after filing

1. Summons is served

The respondent must receive legally sufficient summons. If the respondent cannot be found despite diligent inquiry, the court may authorize publication once a week for two consecutive weeks, together with delivery to the last known address by registered mail or another method ordered by the court.

A missing, overseas, or uncooperative spouse does not automatically prevent the case, but valid service is essential.

2. The respondent may answer

The special rule provides a period for a verified answer. If the respondent does not answer, the court does not simply declare that spouse in default and grant the petition. The marriage ground must still be proved.

3. The prosecutor investigates possible collusion

When no answer is filed or the answer raises no genuine issue, the court directs the public prosecutor to investigate whether the spouses are colluding. The State participates because marital status cannot be changed merely by agreement.

A court cannot grant annulment or nullity solely because:

both spouses consent;
the respondent admits every allegation;
the parties submit an agreed statement of facts; or
the case is “uncontested.”

4. Pre-trial is mandatory

Both parties and counsel are generally required to appear. The parties identify the issues, witnesses, documents, expert evidence, and any lawful agreements concerning collateral matters.

Mediation may address matters the law permits the spouses to settle, such as some property or parenting arrangements. The parties cannot compromise the validity of the marriage itself, civil status, future support, or future legitime.

5. Trial and evidence

The judge personally receives the evidence on the marital ground. Judgment on the pleadings, summary judgment, and confession of judgment are prohibited. The court may restrict courtroom access and access to records to protect privacy.

6. Decision, finality, and appeal

A favorable decision generally becomes final after the applicable 15-day period from notice if no authorized motion or appeal is filed. Under the special rule, a motion for reconsideration or new trial is a precondition to an appeal from the decision. Never calculate a live deadline from a general article alone; counsel should use the actual dates and modes of service in the record.

7. Decree, property compliance, and registration

Finality of the decision is not always the last step. Depending on the case, the court may require:

liquidation, partition, and distribution of property;
protection of creditors;
custody and child-support orders;
delivery of the common children’s presumptive legitimes;
registration in the civil registries where the marriage was recorded and where the Family Court is located; and
registration of property partition with the proper Register of Deeds.

The prevailing party must cause registration of the decree with the required civil registries and the PSA and report compliance to the court within 30 days after receiving the decree. If summons was served by publication, publication of the decree may also be required.

For an annotated PSA Certificate of Marriage, the PSA instructs applicants first to verify with the Local Civil Registry Office whether the supporting records have been forwarded. Its listed records include the court decree, certificate of finality, certificate of registration, certificate of authenticity, and relevant marriage-certificate copies. See the PSA annotation guidance.

Do not remarry until counsel confirms that the judgment is final, the decree has been issued, all required registrations are complete, and an annotated civil-registry record is available.

Evidence to gather and preserve

Start with certified or official records where available:

PSA Certificate of Marriage and Advisory on Marriages;
marriage-license application, issued license, and certifications from the local civil registrar;
marriage contract and records from the solemnizing officer or religious institution;
PSA birth certificates of both spouses and common children;
records of any earlier marriage, death, annulment, nullity judgment, presumptive-death proceeding, or foreign divorce;
marriage settlements or prenuptial agreements;
land titles, tax declarations, deeds, loan records, bank records, business records, insurance policies, and debt statements;
medical or treatment records lawfully obtainable and genuinely relevant to a pleaded ground;
contemporaneous letters, messages, emails, photographs, calendars, and financial records;
police, barangay, social-welfare, school, employment, or rehabilitation records, when relevant and lawfully available; and
names and contact information of witnesses with personal knowledge.

For psychological-incapacity cases, create a factual chronology covering life before the marriage, courtship, the wedding period, married life, recurring conduct, efforts to address the problem, and the effect on specific marital obligations. Identify witnesses who knew the allegedly incapacitated spouse before and during the marriage.

Preserve original files, complete message threads, metadata, envelopes, receipts, and certified copies. Do not alter screenshots, coach witnesses, access another person’s protected accounts, or secretly record private communications without first obtaining legal advice on privacy, anti-wiretapping, and evidence rules.

Effects on children, support, and property

Nullity or annulment does not erase parenthood or a child’s right to support.

Children conceived or born before an annulment judgment becomes final remain legitimate. Children conceived or born before a judgment declaring an Article 36 marriage void becomes final are likewise legitimate. For other void marriages, the general rule and statutory exceptions concerning filiation must be examined carefully.

Custody is decided according to the child’s welfare and the applicable family-law rules, not as a reward for winning the marital-status issue. The court may issue provisional orders for custody, visitation, and support while the case is pending.

Property treatment is highly fact-dependent. It can vary with:

the ground for nullity or annulment;
the marriage settlement and applicable property regime;
good or bad faith;
whether the marriage was void from the beginning;
title and proof of actual contributions;
existing debts and creditor rights; and
prior transfers or encumbrances.

Do not assume that every asset will automatically be divided equally or that property titled in one spouse’s name is automatically excluded.

Common and costly mistakes

Treating incompatibility, infidelity, abandonment, or abuse as an automatic Article 36 case.
Filing under “fraud” based on a lie not included in Article 46.
Missing an annulment deadline or continuing voluntary cohabitation after discovering the defect.
Submitting a generic psychological report without credible facts connecting the incapacity to the time of marriage and essential marital obligations.
Assuming a cooperative respondent guarantees approval.
Suppressing unfavorable evidence, inventing witnesses, or arranging a collusive case.
Giving an incomplete or false address for either spouse.
Failing to disclose children, property, debts, previous cases, or an earlier marriage.
Believing that a church decree, private separation agreement, or foreign divorce automatically changes Philippine civil status.
Remarrying after receiving a favorable decision but before finality, issuance of the decree, and required registration.
Paying anyone who promises a guaranteed result, a secretly arranged judge, or a decree without personal testimony and genuine court proceedings.

When legal help is urgent

Seek immediate legal advice if:

an annulment deadline may be approaching;
either spouse plans to remarry or has already remarried;
there is an earlier marriage, missing spouse, foreign divorce, or disputed citizenship;
property is being sold, hidden, mortgaged, or transferred;
a child has been taken, concealed, threatened, or denied necessary support;
summons, a court order, or an adverse decision has been received; or
there is violence, stalking, coercion, or an immediate safety risk.

Annulment proceedings are not a substitute for emergency protection. Republic Act No. 9262 provides barangay, temporary, and permanent protection orders in covered violence-against-women-and-children cases. A person in danger should seek assistance from law enforcement, the barangay VAW desk, social-welfare authorities, or a lawyer without waiting for a nullity or annulment case to progress. See the Anti-VAWC Act and the Philippine Commission on Women’s official guide.

Those unable to afford private counsel may ask the Public Attorney’s Office or an Integrated Bar of the Philippines legal-aid office about eligibility and available assistance.

Frequently asked questions

Can we obtain an annulment because we both agree to separate?

No. Agreement does not create a legal ground, and the court must independently evaluate evidence. The spouses may settle only matters the law permits them to compromise.

Is a psychologist or psychiatrist always required for psychological incapacity?

No. Expert testimony or a clinical diagnosis is not legally mandatory. It may nevertheless be useful, depending on the available witnesses, records, and complexity of the case.

Can the case continue if my spouse refuses to participate?

Potentially, yes, after valid service. The respondent is not automatically declared in default, and the petitioner must still prove the ground. The prosecutor also checks for collusion.

How long does the case take?

There is no reliable universal period. Duration depends on service of summons, publication, court congestion, prosecutor review, disputed evidence, expert and witness availability, property proceedings, post-judgment motions, and appeals. Be cautious of guaranteed completion dates.

How much does it cost?

There is no single official package price. Costs may include filing and sheriff’s fees, certified records, publication, professional fees, expert work if used, property proceedings, and civil-registry expenses. The clerk of court assesses official court fees; request written engagement terms and receipts.

Can I remarry once the judge grants the petition?

Not immediately. Wait for finality, entry of judgment, the decree, completion of property and children-related requirements when applicable, registration with the required registries, and an annotated PSA record.

Does a church annulment allow a civil remarriage?

No. A religious decree does not replace a Philippine civil-court judgment and civil-registry compliance.

Can I file while working or living abroad?

Possibly, but venue, the six-month residence rule, personal verification, execution of documents abroad, service, and required personal appearances must be assessed before filing. An attorney-in-fact cannot simply replace the petitioner for the personal verification and certification required by the special rule.
