Quick answer

In the Philippines, 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 specific defect existing at that time—such as lack of required parental consent, fraud recognized by law, force, certain mental conditions, incurable physical incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.
Declaration of nullity applies to a marriage that was legally void from the beginning. Common examples include a marriage without a required marriage license, a bigamous marriage, an incestuous marriage, and a marriage void because of psychological incapacity under Article 36 of the Family Code.

Neither remedy is granted merely because the spouses have separated, stopped communicating, fallen out of love, experienced infidelity, or mutually agreed to end the marriage. A proper petition must be filed in the Family Court, a statutory ground must be proved with admissible evidence, and the judgment must become final and be properly registered before either party may safely remarry.

Annulment and nullity are not interchangeable

Although “annulment” is often used as a general term for ending a marriage, Philippine law makes an important distinction.

A voidable marriage remains valid and produces legal effects unless and until a court annuls it. An action must be brought by a person authorized by law and, for most grounds, within a specified period.

A void marriage, in contrast, is considered invalid from its inception. Nevertheless, a spouse who intends to remarry generally cannot simply treat the first marriage as nonexistent. Article 40 of the Family Code requires a final judicial judgment declaring the previous marriage void for purposes of remarriage.

This distinction affects:

Who may file the case
The applicable filing deadline
The evidence required
The status of the children
The property regime
The consequences of remarriage
The liquidation and registration requirements after judgment

Grounds for declaration of nullity

A declaration of absolute nullity may be sought when the marriage was void from the beginning under the Family Code.

Absence of an essential or formal requisite

A marriage is generally void when an essential or formal requisite was absent, subject to statutory exceptions. The essential requisites are:

Legal capacity of the parties
Consent freely given in the presence of the solemnizing officer

The formal requisites are:

Authority of the solemnizing officer
A valid marriage license, unless the marriage was legally exempt from the license requirement
A marriage ceremony in which the parties personally appeared and declared before the solemnizing officer and at least two witnesses of legal age that they took each other as spouses

An irregularity in a requisite is not necessarily the same as its complete absence. For example, an error in the processing or recording of a marriage document does not automatically make the marriage void.

Marriages specifically declared void by Article 35

These include:

A marriage involving a party below 18 years old
A marriage solemnized by an unauthorized person, unless either or both parties believed in good faith that the solemnizing officer had legal authority
A marriage without a license when no lawful exemption applied
A bigamous or polygamous marriage, except a subsequent marriage validly contracted under the rules on presumptive death
A marriage contracted because one party was mistaken about the identity of the other
A subsequent marriage void under Article 53 for failure to comply with the required recording and property-related formalities following a prior annulment or declaration of nullity

The Prohibition of Child Marriage Law, Republic Act No. 11596, also declares child marriage void from the beginning.

Psychological incapacity under Article 36

Psychological incapacity is not simply incompatibility, immaturity, irresponsibility, infidelity, abandonment, addiction, refusal to work, or a difficult personality. These facts may be relevant, but they do not automatically establish Article 36.

Under the Supreme Court’s ruling in Tan-Andal v. Andal, G.R. No. 196359, May 11, 2021, psychological incapacity is a legal—not necessarily medical—concept. The evidence must show:

Clear acts of dysfunctionality reflecting an inability to understand and comply with essential marital obligations
A genuinely serious psychic cause
A durable or enduring aspect of the spouse’s personality structure
An incapacity that existed at the time of the marriage, even if it became clearly apparent only afterward

Psychological incapacity must be proved by clear and convincing evidence. A psychiatric or psychological diagnosis is not indispensable, and an expert witness is not automatically required. Testimony from people who knew the spouse before and during the marriage may be important. An expert evaluation can still be useful when it reliably explains the evidence, particularly in a factually complicated case.

The key question is incapacity—not mere refusal, neglect, difficulty, bad faith, or marital failure.

Incestuous and public-policy marriages

Articles 37 and 38 declare certain marriages void, including marriages:

Between ascendants and descendants
Between brothers and sisters, whether of full or half blood
Between collateral blood relatives within the fourth civil degree
Between specified adoptive, step, and in-law relations
Between parties when one killed that person’s spouse, or the killer’s own spouse, with the intention of marrying the other

The exact legal relationship and documentary proof of lineage or adoption must be examined carefully.

Grounds for annulment of a voidable marriage

Article 45 permits annulment only for specified causes existing when the marriage was celebrated.

Lack of required parental consent

This applies when a party was at least 18 but below 21 and married without the consent required by law.

The party whose parent or guardian did not consent may generally file within five years after reaching 21. A parent, guardian, or person having legal charge may file before the party reaches 21. Voluntary cohabitation as spouses after reaching 21 may bar annulment on this ground.

Unsoundness of mind

A petition may be brought by the sane spouse who did not know of the other spouse’s condition, by a qualified relative or guardian, or by the affected spouse during a lucid interval or after regaining reason, subject to the conditions in Articles 45 and 47.

If the affected spouse, after regaining reason, freely cohabits with the other as a spouse, the ground may be considered ratified.

Fraud recognized by the Family Code

Not every lie before marriage constitutes legal fraud. Article 46 limits fraud for annulment to:

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

The injured party must generally file within five years after discovering the fraud. Continued free cohabitation after learning the truth may amount to ratification.

Misrepresentations about character, health, social standing, wealth, or chastity do not, by themselves, constitute the statutory fraud required for annulment.

Force, intimidation, or undue influence

The injured party must generally file within five years after the force, intimidation, or undue influence ceased. Voluntary cohabitation after the coercion ended may bar the action.

Physical incapacity to consummate the marriage

The incapacity must:

Have existed at the time of marriage
Involve consummation with the other spouse
Continue to exist
Appear incurable

The injured party must generally file within five years after the marriage. This is a fact-sensitive ground that normally requires appropriate medical evidence.

Serious and apparently incurable sexually transmissible disease

The disease must have existed at the time of marriage, be serious, and appear incurable. The injured party must generally file within five years after the marriage.

This ground should be distinguished from concealment of a sexually transmissible disease, which may constitute fraud and has a different starting point for the five-year period.

Circumstances that do not automatically justify annulment or nullity

Standing alone, the following ordinarily do not constitute sufficient grounds:

Mutual agreement to separate
Loss of affection
Ordinary personality differences
Frequent arguments
Sexual infidelity
Abandonment after the wedding
Failure to provide financial support
Domestic violence
Drug or alcohol abuse
A spouse’s refusal to cooperate in the case
A long period of physical separation
A church annulment

Some of these circumstances may support legal separation, protection orders, support, custody proceedings, criminal complaints, or an Article 36 case when they are manifestations of a qualifying pre-existing psychological incapacity. Their legal effect depends on the complete evidence.

A religious or canonical decree does not by itself change civil status. It may be offered as evidence where relevant, but only a Philippine civil court can issue the judgment needed to alter the parties’ civil marital status under Philippine law.

Who may file and where

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

A petition for declaration of nullity may be filed solely by the husband or wife.
The persons entitled to seek annulment depend on the particular Article 45 ground.
The case must be 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, the petition may be filed where the respondent can be found in the Philippines, at the petitioner’s election.

Family Courts have exclusive original jurisdiction over these cases under the Family Courts Act of 1997. Where no dedicated Family Court exists, a designated Regional Trial Court handles family cases.

Residence and venue should be established honestly. Using a temporary or fictitious address merely to file in a supposedly faster court can lead to dismissal and other serious consequences.

How the court process generally works

1. Legal assessment and evidence review

Counsel should first determine:

Whether the marriage is void, voidable, or valid
The precise statutory ground
Whether an annulment deadline has expired
Whether the available evidence can prove facts existing at the time of marriage
Whether related issues involving children, support, property, violence, or criminal liability require immediate action

2. Preparation and filing of the petition

The petition must state the complete material facts—not merely statutory conclusions. It must identify the common children, the applicable property regime, and the properties involved.

The petitioner must personally sign the verification and certification against forum shopping. A lawyer or attorney-in-fact cannot sign these in the petitioner’s place. Special formalities apply when the petitioner is abroad.

The procedural rule also requires service of copies on the Office of the Solicitor General and the appropriate city or provincial prosecutor within the prescribed period after filing.

3. Summons and the respondent’s answer

The respondent must be validly served with summons. If the respondent cannot be located despite diligent inquiry, service by publication requires prior permission from the court and compliance with the court’s order.

The usual period to answer is 15 days from service of summons. When summons is served by publication, the answer is due within 30 days from the last publication.

A respondent who does not answer is not simply declared in default. The petitioner must still prove the ground, and the State remains involved to prevent collusion and fabricated evidence.

4. Prosecutor’s participation

If no answer is filed, or the answer does not genuinely contest an issue, the court directs the public prosecutor to investigate whether the spouses are colluding.

The prosecutor appears for the State and helps ensure that evidence is neither fabricated nor suppressed. A marriage cannot be annulled or declared void merely through:

An agreement between the spouses
A confession of judgment
A stipulation that the marriage is invalid
The respondent’s failure to oppose the petition

5. Pre-trial, possible mediation, and trial

Pre-trial is mandatory. Both parties are generally required to appear personally, even when represented by lawyers. Permissible issues—such as some property, custody, or visitation arrangements—may be discussed, but the parties cannot compromise the validity of the marriage or their civil status.

At trial, witnesses testify and documents are formally offered in evidence. The judge must independently determine whether the alleged legal ground was proved.

6. Decision, finality, and appeal

A favorable trial-court decision does not necessarily permit immediate remarriage.

The decision generally becomes final after the applicable 15-day period if no authorized motion or appeal is filed. Under the special rule, a party wishing to appeal must first file a timely motion for reconsideration or new trial. A notice of appeal may then be filed within 15 days from notice of the denial of that motion.

The Office of the Solicitor General may also appeal where legally warranted.

7. Property liquidation, children’s interests, and issuance of the decree

Where the parties have properties, the court may need to complete the liquidation, partition, and distribution process. The law also protects the children’s custody, support, and presumptive legitimes.

The decree is issued only after the applicable statutory and registration requirements have been fulfilled. The judgment, property arrangements, and delivery of presumptive legitimes must be recorded as required by Articles 50 to 53 and the Supreme Court rule.

8. Civil-registry annotation

The prevailing party must cause the decree to be registered with the appropriate local civil registries and the Philippine Statistics Authority. The PSA advises applicants first to verify with the local civil registry where the marriage was recorded whether the supporting documents have been forwarded for processing of the annotated Certificate of Marriage. See the PSA guidance on annotation.

Do not attempt to remarry based only on an unsigned ruling, an uncertified photocopy, an unentered judgment, or a lawyer’s statement that the case has been won.

Children, custody, support, and property

A declaration of nullity or annulment does not erase parental obligations.

During the case, the court may issue provisional orders concerning:

Spousal support, when legally proper
Custody and support of common children
Visitation
Administration of community or conjugal property
Other urgent family concerns

The children’s status depends on the legal ground. Article 54 specifically provides that children conceived or born before the finality of a judgment declaring a marriage void under Article 36 remain legitimate. Children of certain subsequent marriages covered by Article 53 are likewise treated as legitimate. Other void marriages may produce different consequences, so the precise ground and dates must be examined.

Property consequences also differ. Void marriages may fall under Articles 147 or 148 rather than the ordinary property regimes governing valid marriages. Good faith, legal impediments, actual contributions, existing titles, creditors, and the interests of common children may materially affect the outcome.

Evidence to preserve

Preserve original documents when available and maintain secure, complete copies of:

PSA certificates of marriage and birth
Marriage-license records and applications
Certifications from the issuing local civil registrar
Records concerning the solemnizing officer’s authority
Previous marriage, death, annulment, nullity, or presumptive-death records
Medical and treatment records
Messages, emails, photographs, recordings, and contemporaneous correspondence lawfully obtained
Police, barangay, hospital, social-worker, rehabilitation, and protection-order records
Employment, financial, school, and household records relevant to marital and parental obligations
Property titles, tax declarations, bank records, loan papers, receipts, and proof of contributions
Names and contact details of witnesses who knew the spouses before and during the marriage
A dated chronology identifying specific events, places, persons present, and available supporting documents

Do not edit screenshots, manufacture conversations, coach witnesses to give false testimony, or obtain private data unlawfully. Preserve electronic files in their original form and retain the devices or accounts from which they came when practicable.

Common and costly mistakes

Choosing psychological incapacity simply because it appears to be the most familiar ground
Treating ordinary marital misconduct as automatic proof of Article 36
Filing an annulment petition after the statutory period has expired
Using a false address to establish venue
Assuming that a missing PSA record proves there was no marriage
Assuming that an absent marriage license always means the marriage was void without checking possible exemptions and civil-registry records
Relying entirely on a psychological report without credible facts and witnesses
Suppressing adverse evidence or presenting rehearsed or fabricated testimony
Ignoring property, creditor, custody, and child-support issues until after trial
Believing that the respondent’s consent guarantees approval
Remarrying before finality, issuance of the decree, and required registration
Confusing a church annulment, legal separation, or foreign divorce with a Philippine civil judgment of nullity or annulment

When legal help is urgent

Seek prompt legal assistance if:

An annulment filing deadline may be approaching
A spouse is threatening violence, harming a child, or disposing of property
Children have been taken, concealed, or denied necessary support
The respondent is abroad or cannot be located
The marriage may be bigamous
A previous foreign divorce or foreign marriage is involved
A party is planning to remarry
Property is being sold, mortgaged, transferred, or hidden
Summons, a court order, or a pre-trial notice has been received
Evidence may be destroyed or witnesses may soon become unavailable

Annulment or nullity proceedings need not be completed before a person seeks protection from violence, child support, custody relief, or appropriate criminal remedies.

Frequently asked questions

Can both spouses jointly obtain an annulment?

They may agree on lawful collateral matters, but they cannot jointly declare their marriage invalid. The petitioner must prove a statutory ground, the prosecutor participates for the State, and the court independently evaluates the evidence.

Can a marriage be annulled because the spouses have been separated for many years?

Lengthy separation alone is not a ground. The facts leading to and surrounding the separation may be relevant if they prove a ground recognized by law.

Is infidelity enough?

Not by itself. Infidelity may support other remedies and may be evidence within a broader factual pattern, but it is not automatically psychological incapacity or statutory fraud for annulment.

Is a psychologist always required for Article 36?

No. Tan-Andal holds that psychological incapacity need not be medically diagnosed and expert testimony is not indispensable. The case must nevertheless be proved by clear and convincing evidence. Whether an expert would materially strengthen a particular case depends on its facts.

What if the other spouse refuses to participate?

Refusal does not automatically defeat the case, but valid service of summons and due process remain essential. The petitioner must still prove the ground. The court cannot grant the petition merely because it is uncontested.

Can the spouses privately agree that the marriage is void?

No. Civil status and the validity of marriage cannot be settled by private agreement. A court judgment is required.

Is there a deadline for filing?

An action or defense for declaration of absolute nullity generally does not prescribe. Annulment grounds have specific filing periods under Article 47, commonly five years measured from the event identified by law. The correct starting date varies by ground.

Can a person remarry immediately after receiving a favorable decision?

No. The judgment must become final, the required property and children-related matters must be completed when applicable, the decree must be issued, and the required civil-registry registrations must be made. Remarrying prematurely may make the subsequent marriage void and may expose the parties to additional legal consequences.

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

There is no legally guaranteed duration or universal price. The total depends on the court’s docket, service of summons, publication, contested issues, number and location of witnesses, expert evidence, property proceedings, appeals, professional fees, and registration expenses. Be cautious of anyone guaranteeing approval by a fixed date.

Is legal separation the same as annulment?

No. Legal separation allows spouses to live separately and affects property and other rights, but it does not sever the marriage bond and does not permit remarriage.
