Quick answer

Annulment and declaration of nullity are different court remedies.

Declaration of nullity applies when a marriage was legally void from the beginning, such as certain bigamous, incestuous, underage, unlicensed, or psychologically incapacitated marriages.
Annulment applies when the marriage was valid when celebrated but was voidable because of a ground recognized by law, such as lack of required parental consent, qualifying fraud, force, incapacity to consummate, or a serious and apparently incurable sexually transmitted disease.

Separation, incompatibility, infidelity, abandonment, violence, or an agreement between spouses does not automatically annul a marriage. These facts may support another remedy—or help prove psychological incapacity—but the specific legal elements still have to be established in court.

A person must not remarry merely because the spouses have separated or even because a trial court has granted the petition. Remarriage should wait until the judgment is final, all required property and children-related steps are completed, the decree and entry of judgment are properly registered, and the civil-registry records have been annotated.

Nullity and annulment are not interchangeable

Remedy	Status of the marriage	Time limit
Declaration of absolute nullity	The marriage was void from the beginning	An action or defense generally does not prescribe
Annulment of a voidable marriage	The marriage is treated as valid until annulled by a final judgment	Strict deadlines depend on the ground
Legal separation	The spouses may live separately, but the marriage bond remains	Different grounds and deadlines apply; neither spouse may remarry
Recognition of a foreign divorce or foreign judgment	Asks a Philippine court to recognize a qualifying foreign decree	A separate remedy with different proof requirements
Church annulment	Concerns the parties’ religious status	It does not, by itself, change Philippine civil status

There is still no general no-fault civil divorce remedy under the Family Code for marriages between Filipinos. Special rules may apply to qualifying foreign divorces and marriages governed by the Code of Muslim Personal Laws.

When a marriage may be declared void

The Family Code recognizes several kinds of void marriages. The exact ground must be identified and proved; a marriage is not void simply because it has failed.

Absence of an essential or formal requirement

A marriage may be void when an essential or formal requirement was absent—not merely irregular—including:

lack of legal capacity to marry;
absence of consent freely given in the presence of the solemnizing officer;
marriage by a person below 18;
solemnization by someone without legal authority, unless either or both parties believed in good faith that the person had authority;
absence of a marriage license, unless a statutory license exemption validly applied;
a bigamous or polygamous marriage, except a subsequent marriage that strictly complied with the rules for an absent spouse presumed dead;
mistake as to the identity of the other contracting party; or
a subsequent marriage that is void under Article 53 because required registration and related steps following an earlier annulment or declaration of nullity were not completed.

A missing PSA record does not necessarily prove that no marriage license existed. The underlying records of the local civil registrar, the marriage-license application, the license itself, and any claimed exemption must be examined.

Psychological incapacity under Article 36

A marriage is void if, when it was celebrated, either spouse was psychologically incapacitated to comply with essential marital obligations, even if the incapacity became evident only later.

This is a legal concept, not simply a psychiatric diagnosis. Under Tan-Andal v. Andal and subsequent Supreme Court decisions, the evidence must establish:

Juridical antecedence: the incapacity already existed when the marriage was celebrated, although its manifestations may have appeared later.
Legal incurability: the condition is enduring and persistent in relation to the particular spouse and marital relationship. Medical incurability is not required.
Gravity: the problem comes from a genuinely serious psychic cause and is more than ordinary immaturity, mood changes, ill will, neglect, refusal, or difficulty performing marital duties.
Actual incapacity: the person was genuinely unable—not merely unwilling—to understand and comply with essential marital obligations.
Clear and convincing evidence: the court must be persuaded by the totality of the evidence, not by labels or conclusions.

A psychologist or psychiatrist is not legally mandatory. Relatives, friends, coworkers, household members, and other people who observed consistent behavior before and during the marriage may provide relevant evidence. Expert testimony may still be useful when it connects life history and observed behavior to the legal requirements; a diagnosis alone is not enough.

Infidelity, addiction, abandonment, abuse, irresponsibility, or failure to provide support does not automatically establish psychological incapacity. Such conduct may be evidence when it forms part of a durable pattern showing a true inability to perform essential marital obligations.

Incestuous and public-policy marriages

Marriages between ascendants and descendants and between siblings, whether of the full or half blood, are void. The Family Code also voids marriages between specified relatives within the fourth civil degree, certain step-relations and relations by affinity, specified adoption relationships, and persons where one killed their own spouse or the other person’s spouse with the intention of marrying.

Child marriage

Under Republic Act No. 11596, a child marriage is void from the beginning, and an action or defense to declare it void does not prescribe. The prohibition applies nationwide. The law separately criminalizes specified acts involving the facilitation, solemnization, and practice of child marriage.

Subsequent marriages involving an absent spouse

A person cannot safely assume that an absent spouse is dead and remarry based only on the passage of time. Article 41 generally requires the statutory period of absence, a well-founded belief that the spouse is dead, and a judicial declaration of presumptive death obtained before the subsequent marriage. Different periods apply when the disappearance involved danger of death.

When a marriage may be annulled

Annulment is limited to the grounds in Article 45 of the Family Code. The ground must have existed when the marriage was celebrated.

Ground	Who may generally file	Deadline and possible ratification
A spouse was 18 to below 21 and married without the required consent of a parent, guardian, or person exercising substitute parental authority	The underage contracting party, or the parent, guardian, or person having legal charge	The contracting party must file within five years after reaching 21. The parent or guardian may file before the contracting party reaches 21. Free cohabitation after reaching 21 may ratify the marriage.
One spouse was of unsound mind, using the Family Code’s terminology	The sane spouse who did not know; a relative, guardian, or person having legal charge of the affected spouse; or the affected spouse during a lucid interval or after regaining sanity	The applicable filer and timing depend on the circumstances, but the case must be brought before the death of either spouse where the rule so requires. Free cohabitation after regaining reason may ratify the marriage.
Consent was obtained by legally recognized fraud	The injured party	Within five years after discovering the fraud. Free cohabitation with full knowledge of the fraud may ratify the marriage.
Consent was obtained through force, intimidation, or undue influence	The injured party	Within five years after the force, intimidation, or undue influence ceased. Free cohabitation afterward may ratify the marriage.
One spouse was physically incapable of consummating the marriage with the other, and the incapacity continues and appears incurable	The injured party	Within five years after the celebration of the marriage
One spouse had a serious and apparently incurable sexually transmitted disease	The injured party	Within five years after the celebration of the marriage

What counts as fraud

Article 46 limits fraud to specified circumstances:

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

The statutory ground concerns concealment; sexual orientation by itself is not the fraud described by Article 46.

Misrepresentation about character, health, rank, fortune, or chastity generally does not constitute the fraud required for annulment. Ordinary lies, undisclosed debts, or disappointment with a spouse will not qualify unless the facts fit an actual statutory ground or another recognized legal remedy.

Conduct that does not automatically end a marriage

The following may be serious but are not, by themselves, grounds for annulment:

long separation;
irreconcilable differences;
loss of love;
incompatibility;
adultery or another affair;
abandonment;
refusal to provide support;
violence or controlling conduct;
gambling, alcohol, or drug problems;
failure to communicate; or
both spouses agreeing that the marriage should end.

Some of these facts may support legal separation, protection under the Anti-Violence Against Women and Their Children Act, criminal or support proceedings, or an Article 36 case if the required psychological incapacity is independently proved.

The court cannot grant nullity or annulment solely because the respondent admits the allegations, fails to appear, or agrees with the petition. The ground must be proved, and the public prosecutor represents the State to guard against collusion, fabricated evidence, and suppression of evidence.

Who may file

The procedural rule generally states that a petition for declaration of absolute nullity may be filed by the husband or wife. For annulment, the proper petitioner depends on the ground and the deadlines shown above.

Standing becomes more complicated in bigamous marriages. In Quirit-Figarido v. Figarido, the Supreme Court emphasized the position of the aggrieved or injured spouse. Depending on the facts, this may include the spouse in the prior subsisting marriage or an innocent subsequent spouse who later discovers the bigamy. A person who knowingly entered a bigamous marriage may lack standing to use that bigamy as the basis for obtaining freedom to remarry.

Because standing in bigamy, foreign-marriage, and estate cases is fact-sensitive, legal advice should be obtained before choosing the petitioner or the remedy.

Where the petition is filed

The case is filed in the Regional Trial Court designated as a Family Court for the proper province or city.

As a general rule, venue is where either the petitioner or respondent has actually resided for at least six months immediately before filing. If the respondent is a nonresident, the special rule permits filing where the respondent may be found in the Philippines, subject to its conditions.

The 2023 amended venue rules address spouses abroad:

If only the petitioner resides abroad, venue is generally the respondent’s Philippine residence.
If both spouses are temporarily abroad for employment, business, education, or another purpose, the available Philippine venues include the habitual residence of either party, at the petitioner’s election, or the place where they last lived together as spouses in the Philippines.

The petition must give the parties’ complete, truthful addresses. Current guidelines generally require a sworn barangay residency certification with a house-location sketch, counsel’s sworn verification of the residency evidence, and supporting documents showing the required period of residence.

Modified documentary requirements apply when the petitioner resides abroad or left the spouses’ habitual residence for a just cause such as violence, criminal activity, addiction, alcoholism, infidelity, or failure to provide support. The reason must be truthfully stated and detailed. A false residence, sham address, or fabricated exemption can result in dismissal and other legal consequences. The current requirements are reproduced in OCA Circular No. 284-2023.

How the court process works

1. Identify the correct remedy and ground

A family-law lawyer should review the marriage certificate, ages and citizenships of the parties, prior marriages, marriage-license records, alleged fraud, events surrounding consent, separation history, children, and property.

The petition must allege ultimate facts that correspond to a legal ground. Simply retelling an unhappy marriage without connecting the facts to the law is insufficient.

2. Prepare the records and evidence

Common starting documents include:

PSA marriage certificate and local civil-registry records;
PSA birth certificates of the spouses and common children;
CENOMAR or Advisory on Marriages, where relevant;
marriage-license application, license, and certification from the issuing civil registrar;
records of earlier marriages, judgments, divorce decrees, or death certificates;
property titles, tax declarations, vehicle records, business records, loans, bank records, and marriage settlements;
complete address and residency evidence; and
documents and witness information supporting the specific ground.

The petition must disclose common children, the property regime, and the properties involved. Omitting material property information may expose the petition to dismissal or later disputes.

3. File and serve the verified petition

The petition must be personally verified and accompanied by a certification against forum shopping signed by the petitioner, not merely by counsel or an attorney-in-fact. Special authentication or consular formalities apply when the petitioner signs abroad.

A copy must be served on the Office of the Solicitor General and the proper city or provincial prosecutor within five days from filing, with proof of service submitted within the same period.

Current electronic-filing rules also apply. The initiating petition is first filed personally, by registered mail, or through an accredited courier. A PDF copy of the petition and accompanying documents must then be emailed to the court within 24 hours after completion of the primary filing; otherwise, it may be deemed not filed. Later pleadings and service are generally completed electronically through the designated email addresses. The Supreme Court extended these rules to annulment and nullity cases through A.M. No. 25-01-13-SC.

4. Serve summons on the respondent

Ordinary service rules apply. If diligent efforts cannot locate the respondent, 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 the court considers sufficient.

Under the special rule, the respondent generally has:

15 days from service of summons to file a verified answer; or
30 days from the last publication when summons is served by publication.

Ignoring summons does not stop the case, but it also does not cause an automatic judgment against the respondent. The respondent is not declared in default in the ordinary way.

5. Collusion investigation, pretrial, and trial

When no answer is filed or the answer does not genuinely contest the petition, the court orders the public prosecutor to investigate possible collusion. The prosecutor continues to represent the State during the proceedings.

Pretrial is mandatory. The parties normally must appear personally and must disclose their evidence and witnesses in their pretrial briefs. The judge personally conducts the trial, except that property matters may be delegated as allowed by the rule.

There is no judgment on the pleadings, summary judgment, or judgment based solely on confession. Even an uncontested petition requires competent proof of every element.

6. Judgment, reconsideration, and appeal

A judgment does not become final immediately. Under the special rule:

a motion for reconsideration or new trial must be filed within 15 days from notice of judgment if a party intends to appeal;
an appeal requires that prior motion and must generally be filed within 15 days from notice of its denial; and
the public prosecutor or Solicitor General may also seek review where permitted.

Do not calculate a deadline from memory. The date and manner of service, holidays, electronic receipt, and applicable rules can affect the computation.

7. Complete the post-judgment requirements

After finality, the parties may still need to address:

liquidation, partition, and distribution of property;
custody and support of common children;
delivery of children’s presumptive legitimes where legally required;
registration of the entry of judgment with the civil registry where the marriage was recorded and where the Family Court is located;
registration of an approved property partition with the Register of Deeds, when required;
issuance and registration of the decree of nullity or annulment; and
annotation of the marriage record with the local civil registrar and the Philippine Statistics Authority.

The prevailing party must generally cause registration of the decree and report compliance to the court within 30 days after receiving it. If summons was served by publication, additional publication of the decree may be required.

The registered decree—not an unsigned draft, verbal court announcement, or unannotated decision—is the best evidence of the changed civil status.

Evidence worth preserving

Preserve evidence before devices are replaced, accounts are closed, or records disappear:

original civil-registry documents and certified copies;
letters, messages, emails, photographs, and their original metadata;
medical records lawfully obtained;
police, barangay, social-worker, school, and hospital records;
financial records showing support, dissipation, hidden assets, or property acquisition;
dated records of significant incidents;
names, addresses, and contact details of witnesses who observed conduct before and during the marriage;
proof of the respondent’s real or last known address; and
certified foreign judgments and authoritative copies of foreign law, where relevant.

Do not enter another person’s account without permission, impersonate them, secretly alter evidence, pressure witnesses, or manufacture documents. Preserve original files and give counsel unedited copies.

Children, support, custody, and property

Filing a case does not suspend parental responsibilities. If no adequate written arrangement exists, either party may ask for provisional orders concerning:

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

Custody is decided according to the child’s best interests, not as a punishment for marital misconduct. A support obligation does not disappear simply because nullity or annulment is being sought.

Children conceived or born before a judgment of annulment becomes final remain legitimate. Children conceived or born before the final judgment in an Article 36 case are likewise treated as legitimate under Article 54. For other void marriages, the child’s status depends on the precise ground and applicable statutory exceptions.

Property consequences also vary:

A voidable marriage remains valid until annulled, after which the applicable liquidation rules operate.
Property in many Article 36 or other void-marriage cases may be governed by co-ownership under Article 147.
Article 148 may apply when the parties were not legally capacitated to marry each other.
Good or bad faith, actual contributions, childcare and homemaking contributions, marriage settlements, and the particular ground may change the result.

Do not assume that a title in only one spouse’s name settles ownership. Likewise, do not sell, transfer, mortgage, or conceal disputed assets without specific legal advice.

Foreign divorce and foreign judgments

A foreign divorce is not automatically effective in Philippine civil records. A Philippine court generally must recognize the foreign judgment, and the party relying on it must prove both:

the authentic foreign judgment; and
the foreign law under which it was issued and which gives it legal effect.

A qualifying divorce involving a foreign spouse may allow the Filipino spouse to remarry under Article 26 as interpreted by the Supreme Court. A divorce between two persons who remained Filipino citizens throughout is generally not recognized under that provision. Citizenship at the relevant dates, who obtained the divorce, and the content of foreign law must be examined carefully.

Recognition of a foreign divorce or foreign judgment is different from asking a Philippine court to annul or declare the marriage void.

Common mistakes to avoid

Choosing “annulment” simply because it is the familiar term, without identifying whether the marriage is void or voidable.
Treating adultery, abandonment, or long separation as automatic grounds.
Filing in a province where neither spouse genuinely resides.
Using a false address or buying fabricated barangay residency documents.
Omitting children, real property, businesses, debts, or earlier marriages.
Assuming a psychologist’s report guarantees an Article 36 judgment.
Coaching witnesses or submitting copied allegations that do not match the evidence.
Paying someone who promises a guaranteed result, a “package annulment,” a secret shortcut, or a decree without personal testimony.
Ignoring summons, pretrial notices, filing deadlines, or electronic-filing requirements.
Remarrying after receiving only the trial court’s decision, without finality, registration, and the required decree.

When legal help is urgent

Seek immediate help if:

there is violence, stalking, coercion, threats, or danger to a child;
a spouse is threatening to take a child out of the country;
assets are being sold, transferred, hidden, or destroyed;
you have received summons or an adverse judgment;
an annulment deadline may soon expire;
either spouse plans to remarry;
a spouse has died while a case is pending;
the case involves a prior marriage, foreign divorce, foreign citizenship, or an absent spouse; or
someone is asking you to sign false residency, property, or psychological documents.

A person experiencing violence may seek assistance independently of the marriage case through the barangay VAW desk, the PNP Women and Children Protection Desk, social services, prosecutors, or the courts. Protection orders, criminal remedies, custody, and support should not be delayed merely because a nullity or annulment case is pending.

Frequently asked questions

Can I file even if my spouse refuses?

Yes. The other spouse’s consent is not required. Proper service and proof of a legal ground are required.

Can we obtain an annulment through a notarized agreement?

No. Private agreements cannot determine civil status or the validity of a marriage. Only a competent court can grant the civil remedy.

Will I automatically win if my spouse does not answer?

No. The respondent is not simply declared in default, and the court must still receive sufficient evidence. The public prosecutor investigates possible collusion.

Is a psychological evaluation required?

No. Supreme Court doctrine treats psychological incapacity as a legal concept, and ordinary witnesses may prove relevant patterns of behavior. An expert may still be valuable in a particular case.

Is there a deadline for psychological-incapacity cases?

An action or defense for declaration of absolute nullity does not prescribe. Annulment grounds, however, have specific deadlines and may be lost through ratification.

Can I remarry when the judge grants the petition?

Not immediately. Wait for finality, the required property and children-related compliance, issuance and registration of the decree, and annotation of the civil-registry records. Confirm completion through counsel and an updated PSA record.

Can the case proceed if my spouse is abroad or cannot be found?

Yes, but venue and service requirements must be followed strictly. Court-authorized publication may be available only after diligent inquiry and compliance with the rule.

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

There is no reliable fixed duration or official all-in price. Timing depends on service, court calendars, the number of witnesses, expert evidence, property and custody disputes, prosecutor and OSG participation, appeals, and post-judgment registration. Filing fees, publication, transcripts, professional fees, evaluations, and registration expenses vary. Be cautious of anyone guaranteeing a result or completion date.

Does a church annulment change my PSA marriage record?

No. A church decree may be relevant evidence in an appropriate civil case, but it does not itself change civil status or authorize remarriage under Philippine civil law.

Is legal separation the same as annulment?

No. Legal separation may permit the spouses to live separately and affect property relations, but it does not dissolve the marriage bond and does not allow remarriage.
