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 an essential or formal requisite 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—for example, lack of required parental consent, unsoundness of mind, legally defined fraud, force or intimidation, incurable incapacity to consummate, or a serious and apparently incurable sexually transmitted disease.

A long separation, abandonment, infidelity, violence, incompatibility, or a mutually agreed breakup does not by itself annul or invalidate a marriage. Such facts may support another remedy or may serve as evidence of psychological incapacity, but only if all legal elements of the chosen ground are proved.

The marriage does not end merely because the spouses sign an agreement, live apart, obtain a church annulment, or secure an overseas divorce that Philippine law does not recognize. A Philippine court judgment must become final, and the required civil-registry and property steps must be completed before either party remarries.

Nullity and annulment are not interchangeable

Point	Declaration of nullity	Annulment
Legal status of marriage	Void from the beginning	Valid until annulled by final judgment
Typical grounds	Articles 35–38 and other applicable provisions of the Family Code	Article 45 of the Family Code
Filing period	Generally does not prescribe	Subject to specific filing periods
Effect on children	Depends on the particular ground and applicable provisions	Children conceived or born before the judgment generally remain legitimate
Need for a court case	Yes, particularly before remarriage and to obtain an operative decree	Yes

The governing provisions appear principally in Articles 35–54 of the Family Code.

When a marriage may be declared void

Absence of an essential or formal requisite

A marriage generally requires:

legal capacity of the parties;
consent freely given in the presence of the solemnizing officer;
authority of the solemnizing officer;
a valid marriage license, unless a statutory exemption applies; and
a marriage ceremony in which the parties personally declare before the solemnizing officer and at least two witnesses of legal age that they take each other as spouses.

The absence, rather than a mere defect or irregularity, in an essential or formal requisite ordinarily makes the marriage void. Important statutory exceptions apply. For example, a marriage solemnized by an unauthorized person is not void on that ground when either or both parties believed in good faith that the solemnizing officer had legal authority.

A missing marriage certificate in PSA records does not automatically prove that no marriage occurred. Registration is evidence of the marriage, but validity must be assessed from the actual ceremony, license, authority, records, and surrounding facts.

Specific void marriages under Article 35

Article 35 identifies, among others:

a marriage involving a party below 18, even with parental consent;
a marriage solemnized by an unauthorized person, subject to the good-faith exception;
a marriage without a required license;
a bigamous or polygamous marriage, except a qualifying subsequent marriage under Article 41;
a marriage involving a mistake as to the identity of the other party; and
a subsequent marriage void under Article 53 for failure to comply with post-judgment requirements.

A claim that no valid marriage license existed normally requires reliable civil-registry evidence. A certification that a license cannot be found must be examined together with the marriage certificate, license number, issuing office’s records, and the evidence concerning any claimed license exemption.

Psychological incapacity under Article 36

Article 36 covers a spouse who, at the time of the wedding, was psychologically incapacitated to comply with the essential obligations of marriage, even if the incapacity became apparent only later.

Under the Supreme Court’s controlling interpretation in Tan-Andal v. Andal, G.R. No. 196359, May 11, 2021, psychological incapacity:

is a legal concept, not necessarily a medically diagnosed illness;
must arise from a genuinely serious psychic cause;
must involve enduring aspects of the person’s personality structure;
must have existed when the marriage was celebrated, although later conduct may reveal it;
must make the person genuinely incapable—not merely unwilling, neglectful, difficult, immature, or ill-tempered—of understanding and complying with essential marital obligations; and
must be established by clear and convincing evidence.

A psychologist or psychiatrist is not legally indispensable. A personal examination of the other spouse is likewise not an absolute prerequisite. Nevertheless, credible expert evidence may be useful, particularly when it explains the spouse’s long-standing personality structure and connects the proven conduct to an incapacity existing at the time of marriage.

Ordinary marital breakdown is insufficient. The court examines the totality of the evidence, including the consistency, duration, seriousness, origins, and effect of the behavioral pattern.

Incestuous and public-policy marriages

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

between ascendants and descendants;
between full- or half-blood siblings;
between collateral blood relatives up to the fourth civil degree;
between specified adoptive and affinity relations; and
where one party, intending to marry the other, killed that person’s spouse or the party’s own spouse.

The exact relationship and applicable law must be verified from civil-registry and adoption records.

A subsisting previous marriage

A second marriage celebrated while a prior marriage remains legally subsisting is generally void. Death, disappearance, separation, or a personal belief that the first marriage was invalid should not be treated casually.

For remarriage, Article 40 requires a final judgment declaring the previous marriage void. Where a spouse has disappeared, Article 41 requires the statutory period, a well-founded belief of death, and a judicial declaration of presumptive death before the subsequent marriage. The relevant period is generally four consecutive years, reduced to two years in the dangerous circumstances specified by law.

Grounds for annulment of a voidable marriage

A court may annul a marriage only on one of the grounds in Article 45, with the defect 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 required consent of a parent, guardian, or person exercising substitute parental authority.

The defect may be ratified if, after reaching 21, the party freely cohabits with the other as spouses.

Unsoundness of mind

A marriage may be annulled when either party was of unsound mind at the time of marriage. The right to sue, the proper petitioner, and possible ratification depend on who knew of the condition and whether the affected spouse later regained reason and freely cohabited with the other.

A mental-health diagnosis alone does not automatically establish this ground. The evidence must address the person’s condition and capacity when the marriage was celebrated.

Fraud specifically recognized by law

Article 46 limits annulment fraud to:

nondisclosure 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 transmitted disease existing at the time of marriage; or
concealment of drug addiction, habitual alcoholism, or homosexuality or lesbianism existing at the time of marriage.

The statutory wording must be applied carefully to the evidence. Misrepresentations concerning character, health, social standing, wealth, or chastity do not constitute annulment fraud under Article 46.

Discovering that a spouse lied about income, debt, employment, personality, prior relationships, or willingness to have children therefore does not automatically establish this ground.

Force, intimidation, or undue influence

The petitioner must prove that consent to the marriage was obtained through force, intimidation, or undue influence existing at the time of the wedding. Later pressure within the relationship, without proof that consent to marry was improperly obtained, is not enough.

Physical incapacity to consummate the marriage

The incapacity must:

have existed when the marriage was celebrated;
relate to consummation with the other spouse;
continue; and
appear incurable.

This is distinct from infertility, refusal to have sexual relations, temporary difficulty, or later-developed incapacity. Medical evidence will commonly be important.

Serious and apparently incurable sexually transmitted disease

The disease must have existed when the marriage was celebrated, be serious, and appear incurable. This ground differs from fraud through concealment of an existing sexually transmitted disease, so counsel should identify the proper theory and filing period.

Filing deadlines for annulment

Annulment claims have strict statutory periods:

Lack of parental consent: the affected party may file within five years after reaching 21; a parent, guardian, or person with legal charge may file before the party reaches 21.
Unsoundness of mind: the sane spouse without prior knowledge, a qualified relative or guardian, or the affected spouse during a lucid interval or after regaining sanity may file within the periods and conditions stated in Article 47.
Fraud: the injured party must file within five years after discovering the fraud.
Force, intimidation, or undue influence: the injured party must file within five years after it disappears or ceases.
Incapacity to consummate or serious and apparently incurable sexually transmitted disease: the injured party must file within five years after the marriage.

Free cohabitation after the affected party acquires full knowledge, regains reason, or becomes free from force may ratify certain voidable defects and defeat annulment.

An action or defense for declaration of absolute nullity generally does not prescribe. This does not justify delaying: witnesses may disappear, records may be lost, property may be transferred, and later relationships may create additional legal complications.

Who may file and where

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

a nullity petition may be filed solely by the husband or wife;
the proper persons authorized by Article 47 and the Rule may file for annulment; and
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, venue may be where the respondent can be found in the Philippines, at the petitioner’s election. Where no separate Family Court exists, the case may be handled by a Regional Trial Court designated to hear family cases under the Family Courts Act of 1997.

The petition must be verified and accompanied by a certification against forum shopping personally signed by the petitioner. It must allege complete facts—not merely recite the statutory ground—and disclose the common children, property regime, and properties involved.

A petitioner abroad must observe the current rules for proper execution or authentication of the verification and certification. Counsel should also confirm the court’s current electronic-filing and documentary-submission requirements. The Supreme Court has implemented electronic-filing measures for civil cases, including marriage cases; requirements can be checked through the Court’s electronic-filing information page.

What happens after filing

The usual process includes:

Filing and docketing. The petition and required documents are filed in the proper Family Court, with payment of assessed fees unless the petitioner qualifies for exemption as an indigent litigant.
Service on government offices. The Rule requires service on the Office of the Solicitor General and the city or provincial prosecutor within the prescribed period.
Summons on the respondent. If the respondent cannot be found despite diligent inquiry, the court may authorize service by publication and other directed means.
Verified answer. The respondent generally has 15 days from service of summons, or 30 days from the last publication when summons is served by publication.
Collusion investigation. When required, the public prosecutor investigates whether the spouses are cooperating improperly to obtain a decree.
Mandatory pretrial. The parties identify the issues, evidence, witnesses, property concerns, child-related matters, and agreements the law permits.
Trial. The petitioner must prove the ground. The respondent’s agreement, silence, or failure to answer does not establish the case.
Decision and possible post-judgment proceedings. The parties, public prosecutor, or Solicitor General may pursue the remedies allowed by the special Rule.
Finality, liquidation, registration, and decree. Property and children’s presumptive-legitime requirements may have to be completed before the decree is issued and registered.

The respondent is not declared in default merely for failing to answer. The court cannot grant nullity or annulment through a confession of judgment, judgment on the pleadings, summary judgment, or a private stipulation that the marriage should end.

Evidence to collect and preserve

The necessary proof depends on the ground, but potentially useful materials include:

PSA and local civil-registry copies of the marriage certificate;
the marriage-license application, license, license-exemption affidavits, and certification from the issuing civil registrar;
birth certificates of both spouses and their children;
records of any earlier marriage, death, annulment, nullity judgment, foreign divorce, or presumptive-death proceeding;
communications before and during the marriage;
contemporaneous journals, emails, messages, photographs, recordings lawfully obtained, and social-media records;
police, barangay, medical, rehabilitation, employment, school, financial, and court records;
proof of the spouses’ residences;
names and contact details of witnesses with personal knowledge, especially relatives, friends, household members, or colleagues who knew the spouse before and during the marriage;
proof concerning assets, debts, titles, bank accounts, businesses, insurance, and major transfers; and
evidence of the children’s needs, schooling, health, present care arrangements, and support expenses.

Preserve original files and complete message threads. Avoid cropping away dates, sender details, or surrounding context. Do not secretly access accounts, impersonate the other spouse, install surveillance software, or obtain evidence through threats or unlawful intrusion.

For an Article 36 case, build a factual history rather than a list of labels. Identify specific conduct, when it began, how often it occurred, who personally observed it, its roots before the wedding, and how it made compliance with identifiable marital obligations genuinely impossible.

Children, support, custody, and property

Filing a marriage case does not suspend parental duties. During the proceeding, the court may issue provisional orders concerning:

support for spouses and common children;
custody and visitation;
administration of community or conjugal property; and
other urgent family matters.

The children’s best interests govern custody questions. Neither spouse should assume that filing first, paying more expenses, marital fault, or the child’s sex automatically decides custody.

The effect on the children’s status depends on the ground. Article 54 expressly treats children conceived or born before the finality of an Article 36 judgment as legitimate. Children conceived or born before an annulment judgment also remain legitimate. Other void-marriage grounds may produce different consequences and require a ground-specific analysis.

Property consequences likewise vary according to:

the ground;
the parties’ good or bad faith;
their marriage settlement and property regime;
when and how each asset was acquired;
whether third-party creditors are involved; and
whether the parties lived under a void union governed by Articles 147 or 148.

A nullity ruling does not automatically mean that one spouse keeps everything registered in that spouse’s name. Do not sell, hide, encumber, or transfer disputed property to defeat the other spouse or creditors.

Finality and remarriage

A favorable trial-court decision is not, by itself, immediate permission to remarry. The parties must account for:

the period for post-judgment remedies;
entry of judgment;
liquidation, partition, and distribution where required;
delivery of the common children’s presumptive legitimes where applicable;
registration in the proper local civil registries and registries of property;
issuance and registration of the decree; and
annotation in the civil-registry records.

Article 53 provides that remarriage without compliance with Article 52 may itself be void. Obtain certified copies of the final judgment, entry of judgment, decree, and properly annotated civil-registry record before arranging another marriage.

A church annulment does not replace the civil-court process. Likewise, a private separation agreement may regulate lawful property or child-related matters, subject to court review where required, but cannot change civil status.

How long and how much will the case take?

There is no universal lawful completion time or standard total price. Duration and cost depend on matters such as:

service of summons, particularly if the respondent is abroad or missing;
the court’s docket;
contested custody or property issues;
number and availability of witnesses;
need for expert or medical evidence;
publication and transcript expenses;
post-judgment motions or appeal; and
liquidation and civil-registry compliance.

Be cautious of anyone promising a guaranteed result, a fixed rapid approval, an “annulment package” requiring no genuine testimony, or a decree obtained solely through connections. A fabricated petition, sham address, coached evidence, or collusive case can lead to dismissal and other legal consequences.

Common mistakes

Treating separation, infidelity, abandonment, abuse, or incompatibility as automatic grounds.
Calling every marriage case an “annulment” without identifying whether the marriage is void or voidable.
Filing under Article 36 based only on a diagnosis or on general allegations that the spouse is narcissistic, irresponsible, or immature.
Assuming that a spouse’s consent guarantees approval.
Using an incorrect residence to create venue.
Waiting until an annulment filing period has expired.
Relying only on a PSA negative certification without examining local civil-registry and marriage-license records.
Filing before developing witnesses and documentary proof.
Ignoring custody, support, debts, businesses, titles, or possible asset transfers.
Assuming a foreign divorce or religious decree automatically changes Philippine civil status.
Remarrying after receiving a decision but before finality, registration, and issuance of the proper decree.
Posting confidential pleadings, psychological reports, or children’s information online.

When legal help is urgent

Consult a Philippine family-law lawyer promptly when:

an annulment deadline may soon expire;
a spouse threatens violence, removes a child, or withholds essential support;
property is being concealed, sold, mortgaged, or transferred;
the respondent’s location is unknown or the respondent lives abroad;
either spouse has a previous marriage or foreign divorce;
the marriage-license record appears missing or irregular;
criminal cases, protection orders, immigration status, or inheritance rights are involved;
one spouse has died while the case is pending;
a new marriage is being planned; or
a fixer offers to manufacture evidence or obtain a guaranteed decree.

In an immediate safety emergency, prioritize physical safety and contact law enforcement, the barangay VAW Desk, or other appropriate authorities. A protection-order or criminal remedy may be necessary independently of the marriage case.

Frequently asked questions

Can we obtain an annulment if both spouses agree?

Agreement can reduce disputes over lawful collateral matters, but it cannot supply a ground. The petitioner must prove a statutory basis, and the prosecutor must guard against collusion and fabricated or suppressed evidence.

Is adultery or having another partner a ground for annulment?

Not by itself. Infidelity may have criminal, civil, custody, support, or legal-separation implications. It may also form part of an Article 36 case only when the totality of evidence proves a serious, enduring, pre-existing psychological incapacity—not merely misconduct or refusal to remain faithful.

Is abandonment a sufficient ground?

No. Abandonment alone does not make a marriage void or voidable. Its history and causes may nevertheless be relevant to psychological incapacity, support, custody, legal separation, or other remedies.

Must the other spouse participate?

The respondent must be properly served, but refusal to cooperate does not necessarily prevent the case from proceeding. It also does not relieve the petitioner of proving the ground. Court approval may be required for substituted service or publication.

Is a psychological evaluation mandatory for Article 36?

No. Tan-Andal holds that psychological incapacity need not be medically diagnosed and that expert testimony is not invariably required. The petitioner must still present clear and convincing evidence satisfying all legal elements. In some cases, a properly supported expert opinion remains valuable.

Can one spouse file while living abroad?

Potentially, yes, but venue and the six-month residence requirement must be carefully assessed. The petitioner must personally execute the verification and certification against forum shopping in the legally accepted manner and must comply with current court filing rules.

Does a foreign divorce end the marriage in the Philippines?

Not automatically in every case. Recognition may depend on the spouses’ citizenships when the divorce was obtained, the foreign law, the validity and finality of the foreign decree, and proper proof in a Philippine court. Foreign-divorce recognition is a distinct remedy and should be evaluated before filing a nullity or annulment petition.

Can a spouse remarry immediately after winning?

No. Wait for finality and complete the decree, liquidation, registration, and annotation requirements applicable to the case. Verify the completed civil-registry record before remarriage.

Is there “automatic annulment” after years of separation?

No. Philippine law does not invalidate a marriage merely because the spouses have lived apart for a particular number of years.
