Quick answer

Annulment and declaration of nullity are different court remedies:

Declaration of absolute nullity applies when the marriage was legally void from the beginning—for example, because an essential requirement was absent, the marriage was bigamous or incestuous, or a spouse was psychologically incapacitated under Article 36 when the marriage was celebrated.
Annulment applies to a marriage that was valid until a court annulled it because of one of the specific defects listed in Article 45, 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 transmissible disease.

Separation, abandonment, infidelity, incompatibility, abuse, or a private agreement does not automatically annul a marriage. Some of those facts may support another remedy or serve as evidence of psychological incapacity, but only when the legal elements are proved.

A person should not remarry merely because the spouses have separated or even because a trial court has issued a favorable decision. For remarriage, the prior marriage must be covered by a final judgment, and the judgment, property partition when required, and decree must be registered as the law and court rules require.

Nullity and annulment compared

Issue	Declaration of nullity	Annulment
Status of marriage	Void from the beginning	Valid until annulled by final judgment
Main legal bases	Articles 4, 35–38, 41, 44 and 53 of the Family Code	Article 45 of the Family Code
Time limit	An action or defense for absolute nullity does not prescribe	Strict periods apply, depending on the ground
Who may file	Generally the husband or wife, subject to special standing rules, particularly in bigamous marriages	The persons and within the periods specified in Article 47
Proof	The particular ground must be proved; Article 36 requires clear and convincing evidence	The particular Article 45 ground and all its elements must be proved
Agreement of spouses	Cannot by itself establish nullity	Cannot by itself establish annulment

The controlling substantive provisions appear in the Family Code of the Philippines. Court procedure is principally governed by the Supreme Court’s Rule on Declaration of Absolute Nullity of Void Marriages and Annulment of Voidable Marriages.

When a marriage is void from the beginning

The Family Code identifies several categories of void marriages.

Absence of an essential or formal requisite

A marriage is generally void when an essential or formal requisite was absent, not merely irregular. Essential requisites include the parties’ legal capacity and consent freely given in the presence of the solemnizing officer. Formal requisites include the officer’s authority, a valid marriage license when required, and a marriage ceremony in which the parties personally declare before the officer and at least two adult witnesses that they take each other as spouses.

An irregularity does not necessarily make the marriage void. For example, a marriage solemnized by an unauthorized person is not void on that ground if either or both parties believed in good faith that the officer had legal authority. A missing license also does not invalidate a marriage that falls within a genuine statutory license exemption.

Marriages expressly void under Article 35

These include:

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 not protected by Article 41;
A marriage contracted through mistake about the other party’s identity; and
A subsequent marriage void under Article 53 because the required post-judgment registrations were not completed.

Psychological incapacity under Article 36

Article 36 applies when, at the time of the wedding, either or both parties were psychologically incapacitated to perform the essential obligations of marriage, even if the incapacity became apparent only later.

In Tan-Andal v. Andal, the Supreme Court clarified that psychological incapacity:

Is a legal concept, not necessarily a medically diagnosed illness;
Must be proved by clear and convincing evidence;
Must have existed when the marriage was celebrated;
Must arise from a durable aspect of the person’s personality structure formed before the marriage;
Must be connected to a genuinely serious psychic cause;
Must manifest in clear acts of dysfunction showing an inability—not merely unwillingness, neglect, difficulty, ill will, or occasional failure—to perform essential marital obligations; and
May be enduring in relation to the particular spouse rather than medically “incurable” in every possible relationship.

A psychological or psychiatric examination is not legally indispensable, and the spouse alleged to be incapacitated need not necessarily submit to an interview. Expert evidence may still be useful, but the court evaluates the totality, credibility, and admissibility of all evidence.

Article 36 is not a general remedy for an unhappy or irretrievably broken marriage. Infidelity, substance abuse, violence, financial irresponsibility, abandonment, or refusal to provide support does not automatically equal psychological incapacity. Such behavior may help prove Article 36 only if credible evidence connects a persistent pattern to a serious psychic cause existing at the time of marriage and to an actual incapacity to perform essential marital obligations.

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 within the fourth civil degree;
Between specified relatives by affinity;
Within specified adoptive relationships; and
Between parties when one killed their own spouse or the other party’s spouse with the intention of marrying the other.

Bigamous marriages and absent spouses

A marriage celebrated while a prior marriage subsists is generally void. Article 41 provides a narrow exception when the prior spouse has been absent for four consecutive years—or two years under circumstances involving danger of death—the present spouse has a well-founded belief that the absentee is dead, and a court has declared the absentee presumptively dead before the later marriage.

Standing in bigamy-based nullity cases is unusually technical. The Supreme Court’s 2024 decision in Quirit-Figarido v. Figarido held that a spouse who knowingly contracted the subsequent bigamous marriage lacked legal capacity to seek its nullification and emphasized the rights of an aggrieved or innocent spouse. Anyone dealing with a prior marriage, foreign divorce, presumed death, or subsequent marriage should obtain advice based on the exact chronology and documents before filing.

Grounds for annulment of a voidable marriage

Every annulment ground must have existed when the marriage was celebrated. Article 45 recognizes only the following grounds.

Ground	Who may file and deadline	Important qualification
A party was at least 18 but below 21 and married without required parental or guardian consent	That party, within five years after turning 21; or the parent, guardian or person having legal charge, before the party turns 21	Free cohabitation as spouses after turning 21 may ratify the marriage
Either party was of unsound mind	The sane spouse who did not know of the condition; a relative, guardian or person having legal charge of the affected spouse before either spouse dies; or the affected spouse during a lucid interval or after regaining sanity	Free cohabitation after regaining reason may ratify the marriage
Consent was obtained through legally defined 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 influence ceased	Free cohabitation after it ceased may ratify the marriage
The other spouse was physically incapable of consummating the marriage, and the incapacity continues and appears incurable	The injured party, within five years after the wedding	The statutory physical incapacity must be proved
The other spouse had a serious sexually transmissible disease that appears incurable	The injured party, within five years after the wedding	The disease must have existed at the time of marriage and meet the statutory seriousness and incurability requirements

Fraud has a narrow legal meaning

For annulment, Article 46 limits 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 transmissible disease existing at the time of marriage, regardless of its nature; or
Concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing at the time of marriage.

Other deceit about character, health, social standing, wealth, or chastity is expressly excluded from Article 45 fraud. The statutory language reflects the law as enacted; whether particular facts satisfy it still depends on admissible proof and applicable constitutional and judicial principles.

Who may file

For nullity, Section 2 of A.M. No. 02-11-10-SC states that the petition may be filed solely by the husband or wife. Heirs generally cannot bring a direct nullity petition governed by that rule, although the validity of a marriage may arise after a spouse’s death in the proper estate proceeding. Bigamous marriages involve additional standing rules, including the rights of the prior or innocent spouse.

For annulment, Article 47 and Section 3 of the Rule identify who may file for each ground and impose the deadlines summarized above. A person who is close to an annulment deadline should seek counsel immediately; negotiations or continued informal separation do not stop the statutory period.

Where and how the case is filed

Family Courts have exclusive original jurisdiction over annulment and nullity cases under the Family Courts Act of 1997.

The petition must be filed in the Family Court of the province or city where either petitioner or respondent has actually resided for at least six months immediately before filing. If the respondent is a nonresident, the petitioner may file where the respondent can be found in the Philippines.

Current residence-verification requirements are strict. Under OCA Circular No. 63-2019, the petition should give the parties’ complete addresses and be supported by prescribed proof, including a sworn barangay residence certification with a location sketch, counsel’s sworn verification of residence, and supporting records such as qualifying utility bills, identification cards, lease and rental records, title, tax declaration, or deed of sale.

The petition must:

State the complete facts constituting the ground;
Identify the common children and their ages;
State the spouses’ property regime and identify the properties involved;
Be personally verified by the petitioner;
Include a certification against forum shopping signed personally by the petitioner; and
Comply with the required copies and service on the Office of the Solicitor General and the city or provincial prosecutor.

The petitioner must serve the OSG and prosecutor with a copy within five days after filing and submit proof of that service within the same period. Noncompliance may result in immediate dismissal.

A petitioner abroad must comply with the special authentication requirements for the verification and certification against forum shopping. An attorney-in-fact cannot sign these documents in place of the petitioner.

Electronic filing now applies

A.M. No. 25-01-13-SC placed annulment and nullity cases within Rule 13-A on electronic filing and service. The initiatory petition is still filed through the permitted primary mode—personal filing, registered mail, or accredited courier—and must also be transmitted in PDF to the court’s official email address within 24 hours. Later pleadings and papers are generally filed and served electronically, subject to the Rule’s exceptions and any specific court order.

Because the special six-copy and service requirements continue to matter, counsel should confirm the receiving court’s current official email address, file-naming instructions, payment process, and required paper sets before filing. Official instructions are available on the Supreme Court’s electronic-filing page and in A.M. No. 25-01-13-SC.

What happens after filing

Summons and answer

The respondent ordinarily has 15 days from service of summons to file a personally verified answer. If the court authorizes summons by publication because the respondent cannot be located after diligent inquiry, publication must be made once a week for two consecutive weeks, with additional service at the last known address as directed by the court. The published summons directs the respondent to answer within 30 days from the last publication.

A respondent who does not answer is not declared in default. The case is not automatically granted.

Investigation for collusion

If no answer is filed, or the answer does not present a genuine issue, the court orders the public prosecutor to investigate whether the spouses are colluding. If the court finds collusion, it must dismiss the petition. If no collusion exists, the case proceeds to mandatory pre-trial.

“Collusion” includes arrangements to manufacture a ground, suppress material evidence, or present a false uncontested case. The parties may settle lawful property, custody, visitation, or existing support issues, but they cannot agree that their marriage is void or should be annulled.

Mandatory pre-trial and trial

Both parties and their lawyers are generally required to appear personally at pre-trial. The parties must disclose their evidence and witnesses in their pre-trial briefs. Failure by the petitioner to appear without a validly proved excuse may lead to dismissal.

At trial, the ground must be proved through admissible evidence. The judge personally hears the case, and the prosecutor represents the State’s interest in preventing collusion and fabricated or suppressed evidence. The court cannot grant the petition solely through:

A confession by the respondent;
An agreed statement that the ground exists;
Judgment on the pleadings; or
Summary judgment.

Court records receive heightened privacy protection. Access by persons other than the parties and their counsel generally requires a court order, and the judge may exclude persons without a direct interest when privacy, psychological harm, decency, or effective testimony so requires.

Temporary protection, support and custody while the case is pending

A spouse does not have to wait for the final decision to request urgent family relief. In the absence of an adequate written arrangement, the court may issue provisional orders covering:

Spousal support;
Custody and support of common children;
Visitation;
Administration of community or conjugal property;
Restraints against disposing of property; and
Other matters requiring immediate action.

The applicable framework appears in the Supreme Court’s Rule on Provisional Orders. Custody is determined according to the child’s welfare and applicable law, not as an automatic reward to the spouse who filed or proved the marital case.

If there is violence, stalking, coercive control, threats, or immediate danger to a woman or her child, do not wait for an annulment or nullity case. Seek assistance from law enforcement, the PNP Women and Children Protection Desk, the barangay VAW Desk, a social worker, prosecutor, or Family Court. Republic Act No. 9262 provides for barangay, temporary, and permanent protection orders.

Evidence to preserve

The required evidence depends on the asserted ground. Preserve lawful originals and reliable copies of:

PSA and local civil-registry marriage and birth certificates;
Marriage-license applications, the license itself, claimed exemption affidavits, and the solemnizing officer’s authority;
Records of prior marriages, death, foreign judgments, judicial recognition of foreign judgments, or presumptive-death proceedings;
Medical records relevant to a pleaded ground, obtained and used lawfully;
Messages, emails, letters, photographs, audio, and social-media records in their original form with dates and metadata where available;
Bank records, remittance records, receipts, loan documents, titles, tax declarations, leases, insurance records, and inventories of assets and debts;
Police, barangay, medical, school, social-worker, or employment records relevant to the facts;
A dated chronology of events before and during the marriage;
Names and contact details of witnesses with firsthand knowledge, including people who knew the spouse before the wedding; and
Proof of actual residence for the six months before filing.

Do not alter screenshots, coach witnesses, create backdated records, access protected accounts without authority, or secretly obtain records through unlawful means. Fabricated or unlawfully obtained material can damage the case and may create separate liability.

Judgment, finality and registration

A favorable trial-court decision is not the last step.

If no timely post-judgment motion or appeal is filed, the decision generally becomes final after the applicable 15-day period, and the court issues an entry of judgment. A party who intends to appeal must first file a motion for reconsideration or new trial within 15 days from notice; after its denial, the notice of appeal must be filed within the prescribed 15-day period.

When there are no properties requiring liquidation, the court may issue the decree after finality and compliance with the Rule. When there are properties, the court must address liquidation, partition, distribution, creditors, custody and support, and delivery of the common children’s presumptive legitimes unless those matters were resolved in an earlier proceeding.

Before the decree is issued in cases requiring property settlement, the following generally must be registered or completed:

The entry of judgment in the civil registry where the marriage was celebrated and where the Family Court is located;
The approved property partition in the proper Registry of Deeds; and
Delivery of the common children’s presumptive legitimes.

The prevailing party must then cause registration of the decree in the required civil registries and with the PSA and report compliance to the court within 30 days after receiving the decree. The PSA advises parties to coordinate first with the local civil registrar where the marriage was registered and verify that the supporting documents have been transmitted before requesting an annotated Certificate of Marriage. See the PSA’s official annotation guidance.

Do not remarry until counsel has confirmed that the judgment is final and that the decree, partition when applicable, and civil-registry entries required by Articles 52 and 53 have been completed. A premature subsequent marriage may itself be void and may expose a person to other legal consequences.

Effects on property and children

The consequences are not identical in every case.

For an annulled marriage, the court generally liquidates the spouses’ applicable property regime, pays obligations, protects creditors, partitions the remaining property, and applies any statutory forfeiture based on bad faith.

Because a void marriage legally did not create a valid spousal property regime, property acquired during the relationship may instead be governed by the special co-ownership rules in Articles 147 or 148. Which article applies depends on whether the parties were legally free to marry each other and on their actual contributions, good faith, and other facts.

Children conceived or born before a judgment annulling a voidable marriage becomes final remain legitimate. Article 54 also expressly treats children conceived or born before the final judgment in an Article 36 case as legitimate. Children from other kinds of void marriages may have a different status unless a statutory exception applies. Never assume that a nullity ruling automatically changes a child’s legitimacy, surname, custody, support, inheritance, or relationship with either parent.

Both parents’ obligations to their children continue. The marital judgment does not erase parental responsibility or automatically terminate inheritance and support rights.

Common and costly mistakes

Calling every case “annulment.” The pleaded remedy must match the marriage’s actual legal defect.
Treating infidelity, abandonment, abuse, or incompatibility as automatic grounds. They are not standalone Article 45 grounds and do not automatically prove Article 36.
Missing an Article 47 deadline. Some annulment claims expire five years after a specific triggering event.
Using a false or temporary address to obtain a preferred court. Venue requires genuine residence and documentary proof.
Assuming the respondent’s agreement guarantees approval. The State participates, and the ground must still be proved.
Inventing a story or suppressing unfavorable evidence. Collusion and fabrication can lead to dismissal and further liability.
Believing that a church annulment changes civil status. A religious decree may have evidentiary relevance but does not replace a Philippine civil judgment.
Assuming an unregistered marriage never existed. Failure to find a PSA record does not necessarily invalidate an otherwise valid marriage; local records and the facts of the ceremony must be investigated.
Selling, hiding or transferring property during the case. Transactions may be challenged and can prejudice creditors, children, or the other spouse.
Remarrying after the decision but before finality and registration. The complete post-judgment process matters.
Confusing nullity with legal separation. Legal separation permits spouses to live separately and affects property, but it does not dissolve the marriage bond or permit remarriage.

When legal help is urgent

Consult a Philippine family-law lawyer promptly if:

An annulment deadline may be approaching;
A second marriage, prior spouse, missing spouse, or foreign divorce is involved;
You received summons or a publication notice;
The other spouse is disposing of, hiding, mortgaging, or withdrawing assets;
A child has been taken, concealed, threatened, or denied necessary support;
You or a child faces violence, stalking, threats, coercion, or unsafe contact;
Immigration, inheritance, criminal bigamy, land, corporate, or substantial debt issues overlap with the marriage;
A party is seriously ill or may die while the case is pending; or
You are considering remarriage but do not yet have a registered decree and an annotated marriage record.

If private counsel is unaffordable, inquire with the Public Attorney’s Office or an Integrated Bar of the Philippines legal-aid office. Eligibility and acceptance depend on the office’s current indigency, merit, conflict, and documentation requirements.

Frequently asked questions

Can we obtain an annulment if both spouses agree?

Agreement may reduce disputes about lawful ancillary matters, but it does not establish a ground. The court still requires evidence, the prosecutor must guard against collusion, and the respondent’s admission cannot by itself support judgment.

Is a psychological evaluation always required for Article 36?

No. Tan-Andal holds that expert opinion is not indispensable because psychological incapacity is a legal concept. A qualified expert may nevertheless be useful when the opinion is reliable and supported by facts. Witness testimony, contemporaneous records, and evidence of conduct before and during the marriage can also be important.

Can the respondent prevent the case simply by refusing to participate?

Not necessarily. The court can proceed after valid service, but it cannot declare the respondent in default or automatically grant the petition. The petitioner must still prove every element, and the prosecutor must investigate possible collusion.

Is adultery or having another partner enough?

No. Sexual infidelity is not itself an Article 45 annulment ground. It may support legal separation or other proceedings and, in a properly proved case, may form part of a broader pattern relevant to Article 36. The court still needs proof of psychological incapacity existing at the time of marriage.

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

There is no reliable fixed duration or universal total cost. Timing depends on service of summons, publication if necessary, prosecutor and court schedules, contested evidence, expert participation, property liquidation, post-judgment motions, appeals, and civil-registry processing. Costs may include filing and sheriff’s fees, publication, transcripts, certified records, professional fees, expert expenses, registration, and property-transfer expenses.

Can I file while working or living abroad?

Potentially, yes, if Philippine jurisdiction, venue, residence, signature, authentication, service, and electronic-filing requirements are satisfied. The petitioner must personally sign the verification and certification against forum shopping; an attorney-in-fact cannot substitute for the petitioner. Plan consular execution and court appearances with counsel before filing.

Can I remarry once the judge grants the petition?

Not immediately. Wait for finality, entry of judgment, issuance and registration of the decree, required property and presumptive-legitime compliance, and annotation of the marriage record. Obtain the registered decree and an updated PSA Certificate of Marriage before relying on a capacity to remarry.

Does nullity or annulment automatically decide custody and support?

No. The court may decide those issues in the same proceeding or recognize earlier rulings, but custody and support follow their own legal standards. The child’s welfare is paramount, and both parents remain responsible for lawful support.
