Quick answer

Annulment and declaration of nullity are different court remedies.

Declaration of nullity applies when the marriage was void from the beginning—for example, because an essential legal requirement was absent, the marriage was bigamous, the parties were within a prohibited relationship, or one or both spouses had psychological incapacity under Article 36.
Annulment applies to a marriage that was valid until annulled because a specific defect already existed when it was celebrated, such as lack of required parental consent, qualifying fraud, force, unsoundness of mind, incurable incapacity to consummate the marriage, or a serious and apparently incurable sexually transmitted disease.

Separation, incompatibility, infidelity, abandonment, abuse, or a mutual wish to end the marriage does not automatically establish either remedy. The legally recognized ground must be alleged and proved in the proper Family Court. A spouse may oppose the case, but cannot prevent it merely by refusing to sign, answer, or appear.

Do not remarry simply because the spouses have separated or even because the trial court has issued a favorable decision. Remarriage should wait until the judgment is final, the required decree and registrations have been completed, and all applicable requirements concerning property and the children’s presumptive legitimes have been satisfied.

Annulment and declaration of nullity are not interchangeable

A void marriage is legally inexistent from the beginning, although a judicial declaration is generally required before either spouse may remarry and to settle civil-registry, property, inheritance, custody, and other legal consequences.

A voidable marriage is considered valid until a court annuls it. If no proper case is filed within the applicable period, or if the defect is legally ratified by free cohabitation in circumstances specified by law, annulment may no longer be available.

These remedies are also different from:

Legal separation, which permits the spouses to live separately and affects property relations but does not dissolve the marriage bond;
Church annulment, which does not by itself change civil status under Philippine law;
Recognition of a foreign divorce, which is a separate proceeding requiring proof of the foreign decree and applicable foreign law; and
Divorce governed by the Code of Muslim Personal Laws, which applies only in circumstances covered by that special law.

When a marriage may be declared void

The principal grounds appear in Articles 35 to 38 and related provisions of the Family Code.

Absence of an essential or formal requirement

Subject to statutory exceptions, a marriage may be void when:

A party was below 18 at the time of marriage, even if a parent or guardian consented;
The solemnizing officer lacked legal authority, unless either or both parties genuinely believed in good faith that the officer was authorized;
There was no valid marriage license and no statutory license exemption applied;
One party mistook the other person’s identity;
The marriage was bigamous or polygamous and did not fall within the narrow rules governing a spouse judicially declared presumptively dead; or
A subsequent marriage was contracted without complying with Article 52 after a prior marriage had been annulled or declared void.

The absence of a marriage certificate from PSA records does not necessarily prove that no valid marriage occurred. Conversely, the existence of a registered certificate does not cure every substantive defect. The ceremony, license records, authority of the solemnizing officer, civil-registry entries, and surrounding facts must be examined together.

Psychological incapacity under Article 36

Psychological incapacity is a legal—not merely medical—concept. It requires clear and convincing evidence of a serious and enduring incapacity to understand and comply with essential marital obligations. The roots of the incapacity must have existed when the marriage was celebrated, although its manifestations may become apparent only later.

The Supreme Court clarified in Tan-Andal v. Andal, and recently restated in Soto v. Reyes-Soto, that:

A clinical diagnosis or named personality disorder is not indispensable;
Expert testimony is not mandatory;
Ordinary witnesses who knew the spouses before and during the marriage may provide relevant evidence;
The court considers the totality of the evidence;
“Incurability” is legal rather than strictly medical and concerns an enduring condition in relation to the particular spouse; and
Mere refusal, neglect, immaturity, ill will, occasional outbursts, poor choices, unhappiness, or ordinary marital difficulty is insufficient.

A psychologist’s or psychiatrist’s report can assist the court, but it is neither an automatic requirement nor a guarantee of success. It must be supported by reliable information and connected to the legal elements. A report consisting only of labels and conclusions may carry little weight.

Incestuous and prohibited marriages

The Family Code also declares void certain marriages between close blood relatives and specified relationships involving adoption, step-relations, and affinity. A marriage is likewise void when one party, intending to marry the other, killed that person’s spouse or their own spouse.

A prior marriage that was supposedly void

A person cannot safely treat a previous marriage as nonexistent and remarry based only on personal belief or legal advice. Article 40 requires a final judicial declaration of the prior marriage’s nullity for purposes of remarriage. Contracting another marriage without the required judgment can create serious civil and criminal consequences.

When a marriage may be annulled

Article 45 permits annulment only for causes that existed when the marriage was celebrated:

Lack of required parental consent. A party was at least 18 but below 21, and the required parent, guardian, or person with substitute parental authority did not consent.
Unsoundness of mind. Either party was of unsound mind, subject to the statutory rules on who may file and possible ratification after the person regains reason.
Fraud affecting consent. Article 46 limits qualifying fraud to specified concealment or nondisclosure, including:
- A previous final conviction for a crime involving moral turpitude;
- Pregnancy by another man at the time of marriage;
- A sexually transmitted disease existing at the time of marriage; or
- Drug addiction, habitual alcoholism, or homosexuality or lesbianism existing at the time of marriage.
The statutory ground concerns concealment that induced consent. Sexual orientation by itself is not stated as a ground. Ordinary deceit about character, health, social rank, wealth, or chastity is expressly excluded.
Force, intimidation, or undue influence. Consent was not freely given because of coercion meeting the legal standard.
Physical incapacity to consummate the marriage. The incapacity continues and appears incurable.
Serious, apparently incurable sexually transmitted disease. The condition existed at the time of marriage.

Infidelity after the wedding, later-developed addiction, abandonment, unemployment, financial irresponsibility, incompatibility, or abuse is not automatically an Article 45 ground. Such conduct may be evidence relevant to another properly pleaded ground, including psychological incapacity, but only if it helps prove every legal element.

Annulment deadlines and ratification

A declaration-of-nullity action or defense generally does not prescribe. Annulment, however, has strict filing periods under Article 47:

Ground	Who may file and deadline
No required parental consent	The affected spouse, within five years after turning 21; or the parent, guardian, or person with legal charge before that spouse turns 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—before the death of either spouse
Fraud	The injured spouse, within five years after discovering the fraud
Force, intimidation, or undue influence	The injured spouse, within five years after the coercion ceased
Incapacity to consummate or serious incurable STI	The injured spouse, within five years after the marriage

Some grounds may be lost through ratification—for example, when the injured spouse freely continues living with the other as husband and wife after discovering the fraud or after the coercion has ceased. Anyone approaching a deadline should obtain legal advice immediately rather than rely on informal calculations.

Who may file

Under the Supreme Court’s special procedural rule, a petition to declare a Family Code marriage void is generally filed by a spouse with the required legal standing. Heirs ordinarily cannot commence the same direct petition after a spouse’s death, although they may be able to raise the marriage’s validity in the proper estate proceeding.

Standing in a bigamous-marriage case is more nuanced. In Quirit-Figarido v. Figarido, the Supreme Court held that an aggrieved or injured innocent spouse of either marriage may seek to have the subsequent bigamous marriage declared void.

For annulment, the proper petitioner depends on the particular Article 45 ground and the deadlines above. Standing can also depend on when the marriage and the proceeding began, especially for older marriages governed by the Civil Code.

Where and how the case is filed

Family Courts—designated branches of the Regional Trial Court—have exclusive original jurisdiction over annulment and nullity cases under the Family Courts Act.

The general venue rule is the Family Court of the province or city where either spouse has resided for at least six months before filing. If the respondent is a nonresident, additional rules apply. Current Supreme Court guidelines require specific residency allegations and documentary proof, and contain special provisions for petitioners temporarily abroad or who left the marital residence for just cause.

The petition must be verified personally by the petitioner, contain the complete material facts, identify the common children, describe the governing property regime and relevant properties, and include the required certification against forum shopping. An attorney-in-fact cannot verify the case in the petitioner’s place merely because the petitioner is abroad.

Since April 24, 2025, annulment and nullity cases have been included in the mandatory electronic-filing and electronic-service coverage of Rule 13-A under A.M. No. 25-01-13-SC. Counsel should use the current official channel designated by the relevant court and comply with any applicable requirements for original documents or paper copies.

The special rule also requires service on the Office of the Solicitor General and the city or provincial prosecutor within five days from filing, with proof submitted to the court within the same period. Noncompliance can put the petition at risk of dismissal.

What normally happens in court

The petition is prepared and filed. The pleading must identify the correct ground and allege facts—not simply quote the Family Code.
Summons is served. The respondent ordinarily has 15 days from service to answer. If court-authorized service is by publication, the rule provides 30 days from the last publication. Publication requires prior court authority and compliance with the prescribed form and accompanying service measures.
There is no automatic default judgment. If the respondent does not answer, the court does not simply grant the petition.
The State participates. The public prosecutor investigates possible collusion when required and appears for the State. The Office of the Solicitor General may also participate. A shared wish to end the marriage does not dispense with proof, and a decision cannot rest on a confession of judgment or an agreement that the marriage is invalid.
Pre-trial is mandatory. The parties identify witnesses, documents, issues, and matters that may lawfully be settled. Custody, support, visitation, and some property questions may be mediated, but the parties cannot compromise the validity of the marriage or fabricate a ground.
The judge personally receives the evidence. The petitioner must prove the asserted ground even if the respondent agrees, does not appear, or admits the allegations.
The court decides the case. A favorable judgment generally becomes final after 15 days from notice if no authorized motion or appeal is filed. A motion for reconsideration or new trial is a precondition to an appeal under the special rule.
Post-judgment requirements are completed. Depending on the case, these include liquidation or partition of property, delivery of children’s presumptive legitimes, registration of the entry of judgment and property documents, issuance and registration of the decree, and civil-registry annotation.

There is no reliable universal completion time. Service difficulties, publication, contested evidence, court calendars, expert testimony, appeals, property disputes, and registration work can substantially affect the duration.

Evidence to gather and preserve

The required evidence depends on the pleaded ground. Useful records may include:

PSA and local civil-registry copies of the marriage certificate;
Marriage-license applications, the license itself, or an official certification concerning the local registrar’s records;
Birth certificates of the spouses and children;
A prior spouse’s marriage or death record, or a final judgment and civil-registry annotation affecting a previous marriage;
Proof of actual residence required by current court guidelines;
Messages, emails, letters, photographs, and contemporaneous journals showing relevant events;
Police, barangay, medical, hospital, counselling, or protection-order records;
School, employment, treatment, or family records lawfully available and relevant to a pre-marriage pattern;
Witnesses who personally observed conduct before and during the marriage;
Titles, tax declarations, loan papers, bank and investment records, business documents, insurance policies, and proof of debts;
Receipts and records showing the children’s school, medical, housing, and daily needs; and
Records of support given, withheld, or requested.

Keep originals and unedited copies. Preserve dates, full message threads, file metadata, envelopes, and information identifying the source. Do not hack an account, impersonate another person, install spyware, secretly obtain protected medical records, or manufacture evidence. Tell counsel how each record was acquired so admissibility and privacy concerns can be addressed.

Children, support, and property

Nullity or annulment does not erase parenthood or terminate a child’s right to support. During the case, the court may issue provisional orders on custody, support, visitation, use of the family home, and administration of community or conjugal property.

Article 54 preserves the legitimate status of children conceived or born before a judgment of annulment becomes final and of children covered by an Article 36 declaration of nullity. It also protects children of a subsequent marriage falling under Article 53. The Supreme Court has confirmed that children legitimated by their parents’ subsequent marriage retain their legitimate status when that marriage is later declared void under Article 36.

For other void marriages, the child’s status and the parties’ property relations depend on the particular ground and facts. Property consequences may fall under Articles 147 or 148 on co-ownership rather than ordinary liquidation of an absolute community or conjugal partnership. In an Article 36 case, partition of co-owned property is generally consequential, not a condition that must be completed before the court can determine whether the marriage is void.

Never hide, transfer, mortgage, or dissipate disputed assets in anticipation of litigation. Ask counsel whether a provisional order, annotation, injunction, or other protective measure is appropriate.

Registration and remarriage

A favorable decision alone is not the last step. The entry of judgment and decree must be registered as required by the Family Code and the Supreme Court rule. Property partition and the children’s presumptive legitimes must also be addressed when applicable.

The prevailing party should verify that the Local Civil Registry Offices and PSA have received and processed the necessary records. PSA’s official guidance lists documents commonly involved in obtaining an annotated Certificate of Marriage, including the court decree, proof of finality, registration documents, and the relevant marriage record.

Before planning another wedding, obtain competent confirmation that:

The judgment is final and executory;
The court has issued the proper decree;
The entry of judgment and decree have been registered;
Applicable property and presumptive-legitime requirements have been completed; and
The PSA marriage record carries the proper annotation.

Common and costly mistakes

Treating “annulment” as a general remedy for any failed marriage;
Selecting psychological incapacity only because it is the most familiar ground;
Assuming abuse, adultery, abandonment, or incompatibility automatically proves Article 36;
Believing a psychological report guarantees approval;
Filing in a convenient province using a false or temporary address;
Omitting an earlier marriage, child, property, debt, or pending case;
Asking the other spouse to admit invented facts or avoid appearing;
Using a fixer who promises a guaranteed decree, secret hearing, or unusually fast result;
Failing to serve the OSG or prosecutor properly;
Ignoring an annulment deadline;
Treating the respondent’s nonappearance as an automatic win;
Failing to register the final judgment and decree; or
Remarrying before all legal and registration requirements are complete.

A genuine case can be damaged by false residency documents, scripted testimony, fabricated records, or collusion. Verify the case number directly with the court and obtain certified court records rather than relying on screenshots or a fixer’s assurances.

When legal help is urgent

Seek prompt advice if:

An Article 47 deadline may be approaching;
A spouse is threatening violence, stalking, withholding a child, or disposing of property;
The respondent is abroad, missing, or avoiding service;
A prior or subsequent marriage may create bigamy issues;
A spouse has died and inheritance rights now depend on marital status;
You are being asked to sign an admission, waiver, property settlement, or affidavit;
Someone offers a guaranteed result without court appearances or a verifiable docket number; or
You are considering remarriage based only on separation, a foreign divorce, or an unregistered decision.

Nullity proceedings are not emergency-protection proceedings. A person experiencing violence may seek police and barangay assistance and protection orders under the Anti-Violence Against Women and Their Children Act without waiting for the marriage case to finish. Immediate child-safety, support, and property concerns can also be raised through appropriate provisional or separate remedies.

Those unable to afford private counsel may ask the Public Attorney’s Office about free legal assistance, subject to its current eligibility, conflict, and merit requirements.

Frequently asked questions

Can we obtain an annulment simply because we both agree?

No. Agreement does not create a legal ground. The petitioner must prove an existing statutory ground, and the State participates to prevent collusion and fabricated evidence.

What happens if my spouse refuses to sign or attend?

A spouse’s signature is not required to commence the case. Once properly served, the proceeding may continue under the rules, but there is no automatic judgment by default.

Is a psychological evaluation mandatory for Article 36?

No. Expert evidence may be useful, but the Supreme Court does not require a clinical diagnosis or expert testimony in every case. The totality and reliability of the evidence control.

Can I file while working abroad?

Possibly. Current rules contain special residency, authentication, and verification requirements for petitioners temporarily abroad. Have Philippine counsel determine the correct venue and documents before filing.

Is there a fixed cost or guaranteed completion time?

No. Legitimate expenses vary with filing requirements, service, publication, professional fees, evidence, experts, property issues, appeals, and registration. No lawyer or fixer can lawfully guarantee approval or a completion date.

Will the children become illegitimate?

Not automatically. Article 54 protects children in annulment cases and Article 36 nullity cases, among other specified situations. Other grounds require case-specific analysis.

Does a church annulment allow civil remarriage?

No. A religious decree does not replace a civil judgment and the required Philippine civil-registry process.

Does a foreign divorce automatically update my Philippine status?

No. A qualifying foreign divorce generally must first be judicially recognized in the Philippines, with the decree and applicable foreign law properly proved. PSA provides separate guidance on foreign-divorce annotation.

Can I remarry immediately after receiving the decision?

No. Wait for finality, the decree, required registrations, and compliance with Articles 52 and 53 where applicable. Confirm completion through certified court and civil-registry records.
