Quick answer

Annulment and declaration of nullity are different court cases:

Declaration of nullity applies when the marriage was void from the beginning, such as certain marriages involving an existing prior marriage, prohibited relationships, lack of an essential or formal requisite, child marriage, or psychological incapacity existing when the marriage was celebrated.
Annulment applies to a marriage that was valid until annulled because a specific defect existed at the time of marriage, such as lack of required parental consent, fraud recognized by law, force, certain mental conditions, physical incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible infection.

Separation, abandonment, infidelity, incompatibility, violence, or years of living apart do not by themselves automatically annul a marriage. They may, however, be relevant evidence when connected to a legally recognized ground.

A person remains legally married until the proper court decision becomes final and the required decree and civil-registry records are completed. A private agreement, church annulment, notarized separation document, or long separation does not authorize remarriage.

Annulment versus declaration of nullity

Issue	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid until annulled
Main legal basis	Family Code Articles 35–38, 40–44, 53 and applicable special laws	Family Code Article 45
Filing deadline	Generally does not prescribe, subject to rules on who may bring the direct action	Strict deadlines apply and depend on the ground
Common example	Psychological incapacity under Article 36	Consent obtained through legally defined fraud
Need for a court case	Yes, particularly to establish marital status and before remarriage	Yes
Effect of reconciliation or continued cohabitation	Depends on the alleged ground and facts	Some grounds can be ratified by freely cohabiting after the defect ends or is discovered

“Annulment” is often used casually to describe both remedies. In court, however, the petition must identify and prove the correct statutory ground.

When a marriage may be declared void

The Family Code identifies several kinds of void marriages. These include, subject to statutory exceptions and the evidence:

A marriage where either party was below 18 at the time of celebration, even with parental consent.
A marriage solemnized by a person without legal authority, unless one or both parties believed in good faith that the solemnizing officer had authority.
A marriage celebrated without a license when no lawful exemption applied.
A bigamous or polygamous marriage, except a marriage validly contracted under the Family Code’s rules on presumptive death.
A marriage involving a mistake as to the identity of the other party.
A subsequent marriage void under Article 53 because the requirements following a prior annulment or declaration of nullity were not completed.
A marriage where, at the time of celebration, either spouse was psychologically incapacitated to comply with essential marital obligations.
An incestuous marriage or another union prohibited by public policy under Articles 37 and 38.
A subsequent marriage contracted after obtaining a declaration of presumptive death in bad faith, as addressed by Article 44.
A child marriage covered by Republic Act No. 11596, which is void from the beginning and may be challenged without prescription.

The exact classification can be difficult. For example, the absence of a marriage-license record is not always conclusive: some marriages are legally exempt from the license requirement, and the available civil-registry records must be examined.

Psychological incapacity is not ordinary marital failure

Article 36 does not make every unhappy or failed marriage void. Psychological incapacity is a legal concept describing an enduring aspect of a spouse’s personality structure that makes compliance with essential marital obligations genuinely impossible—not merely difficult, neglected, or refused.

Under the Supreme Court’s controlling decision in Tan-Andal v. Andal, the evidence must establish:

Gravity: the condition reflects a serious inability to perform essential marital obligations, rather than ordinary immaturity, occasional misconduct, incompatibility, or ill will.
Juridical antecedence: the incapacity existed when the marriage was celebrated, although its manifestations may have become clear only later.
Legal incurability: the condition is so enduring in relation to the particular spouse that the marital obligations cannot realistically be performed.

The petitioner must prove psychological incapacity by clear and convincing evidence. A psychiatric diagnosis or expert witness is not legally indispensable, because psychological incapacity is not strictly a medical illness. Expert evidence may nevertheless be useful in an appropriate case. Relatives, friends, records, communications, and other witnesses may help establish the spouse’s personality structure, history, and persistent pattern of behavior.

Addiction, violence, abandonment, infidelity, financial irresponsibility, or criminal conduct is not automatically psychological incapacity. The court considers whether the proven facts demonstrate the serious, pre-existing inability required by Article 36.

Grounds for annulment

Under Article 45, a marriage may be annulled when one of the following existed at the time of marriage:

A party was at least 18 but below 21 and married without the required consent of a parent, guardian, or substitute parental authority.
A party was of unsound mind, unless that person later freely cohabited with the other spouse after regaining reason.
A party’s consent was obtained by fraud as specifically defined by law, unless the injured spouse later freely cohabited with the other after discovering the fraud.
Consent was obtained by force, intimidation, or undue influence, unless the injured spouse later freely cohabited with the other after it ceased.
A party was physically incapable of consummating the marriage, and the incapacity appeared continuing and incurable.
A party had a serious and apparently incurable sexually transmissible infection.

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

Nondisclosure 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 infection existing at the time of marriage.
Concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing at the time of marriage.

Misrepresentations about character, health, rank, fortune, or chastity generally do not constitute the statutory fraud required for annulment.

Filing deadlines for annulment

The deadline depends on the ground:

No required parental consent: the parent or guardian may sue before the affected spouse reaches 21. The affected spouse may sue within five years after reaching 21.
Unsound mind: the spouse who did not know of the condition, or a relative or guardian of the person of unsound mind, may sue within the periods specified in Article 47, generally before the death of either spouse. The affected spouse may sue during a lucid interval or after regaining reason.
Fraud: the injured spouse must file within five years after discovering it.
Force, intimidation, or undue influence: the injured spouse must file within five years after it ceased.
Physical incapacity to consummate or serious incurable sexually transmissible infection: the injured spouse must file within five years after the marriage.

A petition to declare a void marriage absolutely null generally does not prescribe under Article 39. That does not eliminate evidentiary problems, standing requirements, or other procedural defenses. Delay can make records and witnesses harder to obtain.

Who may file and where

Under the Supreme Court’s Rule on Declaration of Absolute Nullity of Void Marriages and Annulment of Voidable Marriages:

A direct petition for declaration of nullity may generally be filed only by a husband or wife with legal standing under the rule and applicable jurisprudence.
A petition for annulment is filed by the person authorized under Article 47 for the particular ground.
Special standing rules may apply to a bigamous subsequent marriage. The Supreme Court has recognized the injured spouse in the prior subsisting marriage as having standing to challenge that subsequent marriage. The exact marriages involved and the relief requested should be reviewed carefully.

The case is filed in the Family Court, or the designated Regional Trial Court acting as a Family Court, in the province or city where the petitioner or respondent has resided for at least six months before filing. If the respondent is a nonresident, the rule permits filing where the respondent may be found in the Philippines, at the petitioner’s election.

Residence must be genuine. Courts may require proof such as government-issued identification, leases, utility records, employment documents, or other evidence of actual residence.

How the court process generally works

Legal and factual assessment. A lawyer examines the marriage certificate, circumstances existing at the wedding, possible grounds, witnesses, property, children, and any prior marriages or court cases.
Preparation and filing. The verified petition must state the complete material facts—not merely legal conclusions—and include the required certification against forum shopping. Copies must be furnished to the Office of the Solicitor General and the appropriate public prosecutor.
Service on the respondent. The respondent is served with summons and the petition. Service by publication is permitted only under the rules and with court authority when justified.
Investigation for collusion. If the respondent does not answer, or if the answer does not genuinely contest the case, the court directs the public prosecutor to investigate whether the parties colluded or fabricated evidence. Marriage cases cannot be won by agreement, confession of judgment, or default alone.
Pre-trial. Pre-trial is mandatory. The court identifies the issues, witnesses, documents, possible stipulations, support, custody, visitation, property matters, and provisional arrangements.
Trial. The petitioner and witnesses present admissible evidence. The respondent may contest the petition. The State, represented through the prosecutor under the authority of the Solicitor General, participates to prevent collusion and protect the institution of marriage.
Decision and post-judgment proceedings. A party cannot appeal the decision without first filing a timely motion for reconsideration or new trial as required by the special rule. These steps have short deadlines, commonly 15 days from notice, so counsel should review the actual order immediately.
Finality, registration, and decree. A favorable decision alone is not the last administrative step. The entry of judgment and, where applicable, the approved liquidation and partition of property and delivery of children’s presumptive legitimes must be completed and registered. The decree must then be registered with the relevant civil registries and the Philippine Statistics Authority.

There is no dependable fixed completion time. Contested facts, problems serving the respondent, court calendars, witness availability, expert evidence, property issues, and appeals can materially affect the duration.

What evidence should be preserved

Preserve original files and make secure backups. Useful evidence may include:

PSA and local civil-registry copies of the marriage certificate.
Birth certificates of the spouses and children.
Marriage-license records or a properly issued certification that no record exists.
Records of prior marriages, deaths, annulments, nullity judgments, foreign divorces, or presumptive-death proceedings.
Messages, emails, letters, photographs, videos, and social-media records in their original form.
Medical, rehabilitation, counseling, school, employment, financial, police, barangay, and court records lawfully obtained.
Proof of residence for venue.
Titles, tax declarations, bank records, loan documents, business records, inventories, and evidence of each spouse’s contributions.
A dated chronology identifying what happened, who witnessed it, and what document supports it.
Names and current contact information of witnesses with personal knowledge of relevant events before and during the marriage.

Do not alter screenshots, coach witnesses, secretly access accounts, or obtain protected records unlawfully. Authenticity, completeness, and lawful collection affect whether evidence can be admitted and trusted.

Children, support, custody, and property

A nullity or annulment case does not erase parental obligations. The court may issue provisional and final orders on custody, visitation, child support, spousal support, protection of property, and administration of community or conjugal assets.

The status of children depends on the particular ground:

Children conceived or born before the final judgment in an annulment case remain legitimate.
Children conceived or born before the final judgment declaring a marriage void under Article 36 are legitimate under Article 54.
Article 54 also protects children conceived or born of the subsequent marriage described in Article 53.
Different rules may apply to children of other void marriages.

Property consequences also vary. Annulled marriages commonly require liquidation of the spouses’ property regime under Articles 50 and 43. For void marriages, Articles 147 or 148 may govern co-owned property, depending on whether the parties were legally capable of marrying each other and whether they lived exclusively as spouses. Bad faith may affect shares, donations, insurance benefits, inheritance, and custody determinations.

Never conceal, transfer, encumber, or dissipate assets to defeat the other spouse’s lawful claims. Ask counsel about provisional orders if property may disappear while the case is pending.

Do not remarry too early

Even a marriage considered void from the beginning requires a final judicial declaration before its nullity may be relied upon for remarriage under Article 40.

Before applying for another marriage license, obtain and verify:

The final court decision.
The certificate or entry of finality.
The decree of annulment or declaration of nullity.
Proof of registration in the required civil registries.
An appropriately annotated PSA Certificate of Marriage.

Article 53 can make a later marriage void if the registration, property partition, and children’s presumptive-legitime requirements of Article 52 were not followed. The PSA’s guidance on annotated marriage certificates recommends first confirming with the local civil registry where the marriage was registered that the supporting documents have been forwarded to the PSA.

Common mistakes

Treating separation, adultery, or abandonment as automatic grounds.
Choosing psychological incapacity without evidence that the condition existed at the time of marriage.
Filing in a place where neither spouse satisfies the residence requirement.
Relying only on the other spouse’s agreement not to oppose the case.
Using generic or copied allegations instead of specific facts and admissible evidence.
Assuming a psychiatrist is always required—or that a psychiatric report alone guarantees success.
Ignoring strict annulment deadlines.
Failing to disclose children, property, prior marriages, or related cases.
Fabricating an address, arranging a “package” with a promised result, or presenting coached testimony.
Remarrying after receiving a favorable decision but before finality, issuance and registration of the decree, and completion of Article 52 requirements.
Confusing a Catholic Church declaration of nullity with a Philippine civil-court judgment. Each operates within a different legal system.

No lawyer, fixer, psychologist, or court employee can lawfully guarantee that a petition will be granted.

When legal help is urgent

Seek prompt advice from a Philippine family-law lawyer when:

An annulment filing deadline may be approaching.
A spouse has threatened violence, taken a child, or withheld essential support.
Property is being sold, hidden, mortgaged, or transferred.
A summons, prosecutor’s notice, court order, or adverse decision has been received.
A new marriage is planned but the prior judgment or PSA annotation is incomplete.
The case involves a foreign spouse, foreign divorce, prior marriage, child marriage, adoption, disputed parentage, or a deceased spouse.
Immigration status, inheritance, insurance, retirement benefits, or criminal exposure may be affected.

If there is immediate danger, prioritize safety and contact emergency services or the nearest police Women and Children Protection Desk. Protection orders and remedies under the Anti-Violence Against Women and Their Children Act may be available independently of a nullity or annulment case.

Those unable to afford private counsel may ask the Public Attorney’s Office or an accredited legal-aid office whether they meet its requirements.

Frequently asked questions

Can both spouses simply agree to an annulment?

No. They may agree on some collateral matters, but they cannot create a ground for annulment or nullity. The court must independently find a statutory ground supported by evidence, and the prosecutor must guard against collusion.

What happens if the respondent refuses to participate?

Refusal does not necessarily stop the case, but it does not produce an automatic judgment either. Proper service, a collusion investigation, and sufficient evidence are still required.

Is adultery a ground for annulment?

Not by itself. It may support another legally recognized claim when the evidence connects it to that ground, and it may have separate civil or criminal implications, but marital infidelity alone is not listed in Article 45.

Is abandonment a ground for nullity?

Not automatically. It may be evidence relevant to psychological incapacity or another issue, but the petitioner must prove all elements of the actual legal ground.

Is a psychological evaluation mandatory?

No. Tan-Andal treats psychological incapacity as a legal, not purely medical, concept. Expert testimony can help, but the court may rely on the totality of competent evidence. The evidence must still be clear and convincing.

Can an annulment be processed only through the PSA?

No. The PSA annotates civil-registry records after the judicial process and required registration. It does not grant annulments or declarations of nullity.

Is legal separation the same thing?

No. Legal separation permits spouses to live separately and affects property and related rights, but it does not dissolve the marriage bond and does not allow either spouse to remarry.

What if a divorce was obtained abroad?

Recognition of a foreign divorce is a separate remedy. Its availability depends on citizenship and the circumstances when the divorce was obtained, and the foreign judgment and applicable foreign law must generally be proved in a Philippine court. The PSA explains the basic post-judgment annotation process in its foreign-divorce guidance.

Are Muslim marriages governed by the same process?

Not always. Marriages and divorces governed by the Code of Muslim Personal Laws may fall under different substantive rules, procedures, and Shari’a court jurisdiction. Obtain advice from counsel familiar with that legal system.
