Quick answer

Annulment and declaration of nullity are different court remedies:

Declaration of absolute nullity applies when the marriage was void from the beginning. Examples include an underage marriage, certain marriages without a required license, bigamous or incestuous marriages, and a marriage affected by psychological incapacity under Article 36.
Annulment applies to a marriage that was valid until annulled because a specific defect existed when it was celebrated—such as lack of required parental consent, legally defined fraud, force, unsoundness of mind, incurable incapacity to consummate the marriage, or a serious and apparently incurable sexually transmitted disease.

Neither remedy is granted simply because the spouses have separated, no longer love each other, agree to end the marriage, or have “irreconcilable differences.” A Family Court must receive evidence and issue a judgment. The other spouse’s agreement is not required, but collusion, fabricated evidence, and a judgment based merely on confession or stipulation are prohibited.

Do not remarry merely because the spouses have separated—or even immediately after receiving a favorable decision. Finality, registration, property and child-related requirements, and issuance of the proper decree must first be completed.

Annulment and nullity are not interchangeable

Issue	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid until annulled by final judgment
Main legal grounds	Family Code Articles 35–38 and other specific provisions	Family Code Article 45
Filing deadline	Generally does not prescribe	Strict periods apply, depending on the ground
Effect of later cohabitation	Generally does not validate a void marriage	May prevent annulment for certain grounds
Evidence required	Proof of the particular ground for nullity	Proof of the Article 45 ground and timely filing

The governing provisions appear in the Family Code of the Philippines. Republic Act No. 8533 amended Article 39 so that an action or defense for absolute nullity does not prescribe.

When a marriage is void from the beginning

A marriage may be declared void when the evidence establishes a ground recognized by law. The principal grounds include:

A party was below 18 when the marriage was celebrated, even if a parent or guardian consented. Child marriage is also expressly void under Republic Act No. 11596, which separately criminalizes specified acts involving its facilitation, solemnization, and adult-child cohabitation.
The solemnizing officer lacked legal authority, unless either or both spouses honestly believed that the officer was authorized. The good-faith exception is important; lack of authority does not automatically invalidate every affected marriage.
There was no valid marriage license when one was legally required. Some marriages are exempt from the license requirement, including qualifying marriages under Articles 27–34. A claimed exemption must satisfy its legal conditions. For example, the five-year-cohabitation exception requires more than an affidavit saying the couple lived together for five years.
The marriage was bigamous or polygamous, unless it falls within the narrow Article 41 exception involving an absent spouse, a well-founded belief of death, the required period of absence, and a prior judicial declaration of presumptive death.
One spouse was mistaken about the identity of the person being married. This is not ordinary disappointment about the spouse’s character or background.
The marriage is void under Article 53 because a former spouse remarried without completing the registration, property-partition, and presumptive-legitime requirements following a judgment of annulment or nullity.
Psychological incapacity under Article 36 affected either spouse when the marriage was celebrated.
The marriage was incestuous under Article 37 or prohibited for public-policy reasons under Article 38, including specified relationships by blood, affinity, or adoption.
Both parties to a subsequent marriage under Article 41 acted in bad faith, as provided in Article 44.

Absence of a marriage certificate from a person’s files, a blank license number, or an apparent error in the certificate does not by itself prove that the marriage was void. Obtain records or certifications from the local civil registrar and, when relevant, evidence concerning the solemnizing officer and the claimed license exemption.

Psychological incapacity under Article 36

Psychological incapacity is a legal concept, not a shortcut for every unhappy or failed marriage. Under the Supreme Court’s controlling decision in Tan-Andal v. Andal, it is not necessarily a mental illness or clinically diagnosed personality disorder.

The evidence must clearly and convincingly show:

serious dysfunctionality that makes a spouse genuinely incapable—not merely unwilling, neglectful, difficult, or occasionally irresponsible—to understand and comply with essential marital obligations;
a durable or enduring aspect of the person’s personality structure;
origins existing before the marriage, even if the incapacity became apparent only afterward; and
a serious psychic cause connected to the failure to perform specific marital obligations.

A psychiatric or psychological diagnosis is not legally mandatory, and the spouse alleged to be incapacitated need not always submit to a personal examination. Expert testimony may nevertheless be helpful when it explains the evidence reliably. Testimony from relatives, friends, coworkers, or others with firsthand knowledge—especially of the spouse’s behavior and history before the marriage—may also be important.

Infidelity, violence, abandonment, addiction, financial irresponsibility, or refusal to work is not automatically psychological incapacity. Such conduct may be relevant only when the totality of evidence connects it to the legally required enduring, serious, and pre-existing incapacity. Some of the same conduct may instead support legal separation, a protection order, or a criminal or civil case.

Grounds and deadlines for annulment

Article 45 limits annulment to six causes that existed when the marriage was celebrated. Article 47 determines who may file and when.

Ground	Who may file	Filing period and important limitation
Party was at least 18 but below 21 and married without required parental or guardian consent	The under-21 party, or the parent, guardian, or person with legal charge	The parent or guardian may file before the party reaches 21. The party may file within five years after reaching 21, unless the party freely cohabited with the spouse after turning 21
Unsoundness of mind	The sane spouse who did not know of it; a relative, guardian, or person with legal charge; or the affected spouse during a lucid interval or after recovery	The eligible relative or guardian may file before either spouse dies. Free cohabitation after recovery may bar the action
Consent obtained by legally defined fraud	The injured spouse	Within five years after discovering the fraud; continued free cohabitation with full knowledge may bar the action
Consent obtained by force, intimidation, or undue influence	The injured spouse	Within five years after the force, intimidation, or undue influence ceased; later free cohabitation may bar the action
Continuing and apparently incurable physical incapacity to consummate the marriage with the other spouse	The injured spouse	Within five years after the marriage
Serious and apparently incurable sexually transmitted disease	The injured spouse	Within five years after the marriage

Article 46 restricts “fraud” to specified matters:

nondisclosure of a final conviction for a crime involving moral turpitude;
concealment by the wife that, when the marriage occurred, 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, homosexuality, or lesbianism existing at the time of marriage.

The statute states that other deceit about character, health, rank, fortune, or chastity is not the kind of fraud that supports annulment. In particular, sexual orientation by itself is not the statutory ground; Article 46 addresses its concealment when existing at the time of marriage.

Because some filing periods run from discovery or from the end of coercion, document the relevant dates immediately. Continued voluntary cohabitation after learning the truth or after the defect ceases can affect the right to sue.

Who may file

Under the Supreme Court’s special procedural rule, a petition for declaration of nullity may generally be filed only by the husband or wife. Annulment may be filed only by the persons and within the periods specified in Article 47.

Standing becomes more complicated when the alleged ground is bigamy. Supreme Court decisions recognize the rights of an innocent or aggrieved spouse, including a spouse in the prior subsisting marriage, while an erring spouse may be barred in particular circumstances. Compare Quirit-Figarido v. Figarido and the Court’s later ruling involving a foreign spouse in G.R. No. 262831. A lawyer should examine which marriage is being challenged, who knew of the prior marriage, citizenship, divorce history, and whether either spouse acted in good faith.

Heirs generally cannot start the spouses’ direct nullity case while the spouses are living. The validity of a marriage may, however, be resolved incidentally when necessary in an estate, heirship, property, or other proper proceeding.

Where and how the case is filed

The petition is filed in the Regional Trial Court branch designated as a Family Court—or the proper RTC where no Family Court has been established. Family Courts have exclusive original jurisdiction over annulment and nullity cases under the Family Courts Act of 1997.

Venue is generally the Family Court of the province or city where either the petitioner or respondent has actually resided for at least six months immediately before filing. If the respondent is not a Philippine resident, the petitioner may choose the place where the respondent can be found in the Philippines.

The petition must state complete addresses and be supported by proof of the claimed residence. Current requirements include a barangay residency certification with a location sketch, counsel’s sworn verification of residency, and supporting records such as qualifying utility bills, identification, lease and rent records, title, tax declaration, or deed. Using a temporary or false address to obtain a preferred court can lead to dismissal and other consequences.

The petition must also:

allege the complete facts supporting the particular legal ground;
identify the common children and their ages;
state the applicable property regime and disclose the properties involved;
be verified and accompanied by a certification against forum shopping personally signed by the petitioner; and
be served on the Office of the Solicitor General and the appropriate city or provincial prosecutor within five days after filing, with proof of service submitted within the same period.

Since April 24, 2025, nullity and annulment cases have been included in mandatory electronic filing and service under A.M. No. 25-01-13-SC. Counsel should confirm the court’s current electronic address or platform, file format, and any companion paper-copy requirements before filing.

What happens after filing

Summons is served. The respondent’s refusal to cooperate does not automatically stop the case. If the respondent cannot be located despite diligent inquiry, the court may authorize publication once a week for two consecutive weeks, together with delivery to the last known address as directed by the court. Do not conceal a known address or falsely claim that the spouse is missing.
The respondent may answer. Under the special rule, the answer is due within 15 days from service of summons, or within 30 days from the last publication when summons is served by publication. A respondent who receives papers should obtain advice immediately rather than assume that silence ends the marriage.
The State checks for collusion. If no answer is filed or the answer presents no genuine issue, the public prosecutor investigates whether the spouses have colluded. A respondent is not declared in default in the ordinary way.
Pre-trial is mandatory. Both parties are generally required to appear personally. Agreements may be reached on lawful matters such as some property, support, or custody issues, but the parties cannot compromise the marriage’s validity, civil status, future support, or future legitime.
The court conducts a trial. The petitioner must prove the legal ground. The judge cannot grant the petition solely because the respondent admits the allegations, fails to appear, or agrees that the marriage should end. No judgment on the pleadings, summary judgment, or confession of judgment is permitted for the ground itself.
The court decides the case. If the petition is granted, the decision must become final. Under the special rule, a motion for reconsideration or new trial must be filed within 15 days from notice. Such a motion is a precondition to appeal; the notice of appeal is generally due within 15 days from notice of its denial.
Property, children, and registration requirements are completed. Depending on the case, this includes liquidation and partition, delivery of the children’s presumptive legitimes, registration with the relevant civil registries and Registry of Deeds, and issuance and registration of the decree.

There is no single legally guaranteed completion time. Service problems, publication, court congestion, disputed evidence, property liquidation, custody issues, and appeals can substantially affect the schedule.

Evidence to collect and preserve

Do not manufacture a case narrative. Preserve original, lawfully obtained evidence and prepare a dated chronology.

Civil-status and marriage records

PSA and local civil registrar copies of the marriage certificate;
birth certificates of the spouses and children;
marriage-license application and license records or an official certification that no record exists;
documents supporting any claimed license exemption;
the solemnizing officer’s authority and available ceremony or church records;
prior marriage certificates, death certificates, judgments, certificates of finality, decrees, and civil-registry annotations; and
foreign judgments, divorce decrees, foreign-law materials, and proof of citizenship when applicable.

For psychological incapacity

a detailed timeline covering childhood, family history, relationships, and behavior before and during the marriage;
messages, emails, letters, photographs, financial records, employment records, and other contemporaneous documents;
medical, rehabilitation, treatment, police, court, or barangay records lawfully available to the party;
names of witnesses with firsthand knowledge, especially knowledge predating the marriage; and
evidence connecting the conduct to specific essential marital obligations, rather than merely proving marital conflict.

For annulment grounds

proof of age and absence of required consent;
records showing when fraud was discovered or coercion ceased;
the relevant final criminal judgment;
appropriate medical evidence;
communications or witness accounts showing concealment, force, intimidation, or undue influence; and
records showing whether the spouses freely cohabited after the defect became known or ceased.

Children, property, and finances

land titles, tax declarations, deeds, condominium records, vehicle records, business interests, investments, loans, and insurance policies;
bank statements and proof of the source of purchase funds;
marriage settlements;
proof of household and child-related expenses;
school and medical records; and
existing support, custody, protection, or property orders.

Back up electronic evidence without editing the original files. Preserve the device, account information, dates, full conversation context, and available metadata. Secret access to another person’s account or device may create separate legal and evidentiary problems.

Effects on children, support, and property

A decree does not erase parental duties. The court may issue provisional orders while the case is pending concerning spousal support, child support, custody, visitation, and administration of community or conjugal property.

The effect on a child’s civil status depends on the legal ground. Children conceived or born before a judgment of annulment becomes final remain legitimate. Article 54 also expressly treats children conceived or born before the finality of an Article 36 judgment as legitimate, as well as children of a subsequent marriage covered by Article 53. Other void marriages can produce different consequences, so a child’s status should not be assumed from the parents’ decree alone.

Property treatment likewise varies according to the ground, the spouses’ property regime, good or bad faith, actual contributions, creditors’ rights, and previous court rulings. Avoid selling, hiding, transferring, or encumbering disputed property without legal advice. Such acts can harm the family, prejudice creditors or children, and complicate the case.

Completing the civil-registry process

A favorable decision alone is not the final administrative step. The applicable judgment, entry of judgment, property partition, and delivery of presumptive legitimes must be registered as required by Articles 52 and 53 and the Supreme Court’s Rule on Declaration of Nullity and Annulment.

The prevailing party must cause registration of the decree and report compliance to the court within 30 days from receiving it. The registered decree is the best evidence of the nullity or annulment and gives notice to third parties.

For an annotated PSA Certificate of Marriage, first verify with the local civil registry where the marriage was registered whether the supporting documents have been forwarded. PSA identifies documents that may be needed, including the decree, certificate of finality, certificate of registration, certificate of authenticity, and relevant marriage-certificate copies. Follow the current PSA annotation guidance.

Do not remarry until counsel confirms that the judgment is final, the decree has been issued and registered, all Article 52 requirements have been satisfied, and no appeal or unresolved registration problem remains. Obtaining an annotated PSA marriage record before remarrying is a prudent safeguard.

Common and costly mistakes

Treating separation, incompatibility, infidelity, or abandonment as an automatic ground.
Filing for annulment when the facts concern a void marriage—or filing for nullity when only an Article 45 ground may apply.
Missing an annulment deadline.
Continuing voluntary cohabitation after discovering fraud, reaching 21, regaining sanity, or being freed from coercion without first obtaining advice.
Using a false residence to file in a supposedly faster court.
Paying a “package” provider who guarantees approval, a fixed completion date, or no court appearance.
Inventing symptoms, coaching witnesses, suppressing property, or arranging a sham defense with the other spouse.
Assuming that the respondent’s nonappearance means automatic victory.
Believing that a church annulment changes Philippine civil status. A religious decree and a civil court judgment are separate.
Remarrying before finality, registration, and issuance of the proper decree.
Using a petition to correct a civil-registry entry as a substitute for the required direct action to invalidate the marriage.
Assuming a foreign divorce automatically changes Philippine records. Judicial recognition may first be required.

When legal help is urgent

Seek legal advice immediately when:

an Article 45 filing period may be running;
summons, a petition, or a court order has already been received;
either spouse plans to remarry;
a prior marriage or foreign divorce may affect the current marriage;
a spouse is missing and presumptive death is being considered;
there are allegations of bigamy, falsified civil-registry documents, or child marriage;
property is being sold, withdrawn, concealed, or transferred;
a child has been taken, denied support, or placed in danger; or
violence, stalking, threats, or coercive control is present.

A nullity case is not an emergency protection remedy. For violence against a woman or her child, Republic Act No. 9262 provides barangay, temporary, and permanent protection orders and related relief. See the official text of the Anti-Violence Against Women and Their Children Act. Immediate safety concerns should be brought to law enforcement, the barangay VAW desk, the prosecutor, or the proper court without waiting for the marriage case.

People who cannot afford private counsel may ask the Public Attorney’s Office about assistance, subject to its indigency, merit, conflict, and operational rules.

Frequently asked questions

Can the case proceed if my spouse refuses to sign or cooperate?

Yes. The respondent’s consent is not required. Proper summons and proof of the legal ground are required. If the respondent does not answer, the court does not simply declare default; the prosecutor’s collusion investigation and the remaining proceedings must still occur.

Can we obtain annulment because we both agree?

No. Agreement is not a legal ground. The court must find a statutory ground based on admissible evidence, and collusion or fabricated evidence can result in dismissal and other consequences.

Is a psychologist always required for Article 36?

No. Tan-Andal states that psychological incapacity is a legal, not necessarily medical, concept and expert testimony is not mandatory. An expert may still be useful depending on the facts and available evidence.

Is cheating enough for annulment or psychological incapacity?

Not by itself. Infidelity may support other remedies and can be relevant evidence, but Article 36 requires proof of serious, durable, pre-existing incapacity. Annulment requires one of the grounds specifically listed in Article 45.

Can I file wherever the process is reportedly faster?

No. Venue depends on actual six-month residence, with a limited rule for a non-resident respondent. Residency must be supported by sworn and documentary evidence.

What if my spouse is abroad or cannot be found?

The case may still proceed, but service must follow court rules. Publication or other authorized service requires a court order and proof of diligent efforts. International service and foreign addresses can add procedural requirements.

How much does the case cost?

There is no universal lawful “package price.” Costs depend on counsel, court fees, certified records, service or publication, travel, evidence, possible experts, property proceedings, and appeal. Ask for a written engagement describing the scope, exclusions, payment schedule, and responsibility for out-of-pocket expenses. No ethical lawyer can guarantee approval.

How long does it take?

There is no fixed completion period applicable to every case. The timetable depends on the court, service of summons, prosecutor’s investigation, pre-trial, number of witnesses, disputed property or custody, and any appeal.

Can I remarry after receiving the judge’s decision?

Not immediately. Confirm finality, entry and registration of judgment, completion of applicable property and presumptive-legitime requirements, issuance and registration of the decree, and the absence of an appeal. Obtain the properly annotated civil-registry record as a practical safeguard.

Does a church annulment permit civil remarriage?

No. A church decree may affect religious status, but it does not by itself change civil status under Philippine law.

What if there is a foreign divorce?

Recognition of a valid foreign divorce may be the proper remedy when the legal requirements under Article 26 and controlling jurisprudence are met. Citizenship when the divorce was obtained, the foreign judgment, foreign law, authenticity, and due process must be proved. This is distinct from an ordinary annulment or Article 36 case.

Does nullity automatically erase possible bigamy liability?

No automatic conclusion should be drawn. Civil status and criminal liability involve different issues. Supreme Court jurisprudence allows a genuinely void ab initio marriage to be raised and proved as a defense in a bigamy prosecution, but the result depends on the precise defect and evidence; a merely voidable marriage is treated differently. Anyone facing overlapping marriages or a criminal complaint should obtain both family-law and criminal-law advice immediately.
