Quick answer

Annulment and declaration of nullity are different court remedies. You cannot simply choose the easier one:

Declaration of absolute nullity applies when the marriage was legally void from the beginning—for example, because a party was below 18, a required marriage license was absent and no exception applied, the marriage was bigamous, the parties were within a prohibited relationship, or a spouse was psychologically incapacitated 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, unsoundness of mind, legally defined fraud, force or intimidation, incurable incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

Separation, abandonment, infidelity, incompatibility, a private agreement, or a church annulment does not by itself end a civil marriage. A spouse who intends to remarry must obtain the proper final court judgment and complete the required civil-registry and property-registration steps. Remarrying too soon may make the subsequent marriage void and may create criminal or property consequences.

The controlling provisions are primarily Articles 35–54 of the Family Code and the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment.

Nullity and annulment are not interchangeable

Issue	Declaration of nullity	Annulment
Legal character of the marriage	Void from the beginning	Valid until annulled by final judgment
Source of grounds	Primarily Articles 35–38, 40–41, 44 and 53	Article 45
When the defect must exist	At or before the celebration of the marriage	At the time of the marriage
Filing period	An action or defense generally does not prescribe	Strict periods apply, depending on the ground
Proof required	The particular ground must be proved; Article 36 requires clear and convincing evidence	The statutory ground and timely filing must be proved
Agreement of the spouses	Cannot substitute for proof	Cannot substitute for proof

The court will not grant either remedy merely because both spouses want to separate. Civil status and the validity of a marriage cannot be compromised, and no judgment may rest only on an admission, an agreed statement that the marriage is invalid, or a confession of judgment.

When a marriage may be declared void

Marriages void under Article 35

A marriage is void from the beginning when:

Either party was below 18 years old, even if a parent or guardian consented. Republic Act No. 11596 also expressly provides that a child marriage is void from the beginning and that an action or defense questioning it does not prescribe. See the Prohibition of Child Marriage Law.
It was solemnized by a person without legal authority, unless either or both parties honestly believed that the solemnizing officer was authorized.
It was celebrated without the required marriage license and no statutory license exemption applied.
It was bigamous or polygamous and did not fall within the narrow rules on a prior spouse’s presumptive death.
One party was mistaken about the identity of the other contracting party.
It was a subsequent marriage made void by failure to comply with Articles 52 and 53 after an earlier annulment or declaration of nullity.

A missing license should not be assumed merely because the couple cannot find their copy. The local civil registrar’s records, the marriage certificate, the claimed license exemption, and the documents executed before the solemnizing officer must be examined.

Psychological incapacity under Article 36

Psychological incapacity is not simply unhappiness, incompatibility, irresponsibility, refusal to change, infidelity, substance use, violence, or abandonment. Those facts may be relevant, but they are not automatically psychological incapacity.

Under the Supreme Court’s current doctrine in Tan-Andal v. Andal, the petitioner must prove by clear and convincing evidence that:

the incapacity existed when the marriage was celebrated, although it may have become visible only later;
it arose from a durable or enduring aspect of the spouse’s personality structure;
it produced clear and serious dysfunction that made the spouse genuinely incapable—not merely unwilling, neglectful, difficult or ill-tempered—of understanding and complying with essential marital obligations;
it was grave, excluding ordinary weaknesses, mood changes and occasional emotional outbursts; and
it was legally incurable or enduring in relation to the particular marital partnership.

The essential obligations include living together, mutual love, respect and fidelity, mutual help and support, shared responsibility for family support and household management, and relevant obligations toward common children.

A psychiatric diagnosis is not legally indispensable. Expert testimony and a personal examination of the allegedly incapacitated spouse are also not mandatory in every case. Nevertheless, an appropriate expert assessment may still be useful when grounded in reliable facts. Courts examine the totality of the evidence, including credible testimony from relatives, friends or others who observed the spouse before and during the marriage.

A case should not be built around a diagnostic label alone. It needs specific acts, a reliable history, a connection to essential marital obligations, and evidence showing that the incapacity was already rooted in the person when the marriage began.

Incestuous and public-policy marriages

Articles 37 and 38 make certain marriages void, including marriages between:

ascendants and descendants of any degree;
full- or half-blood brothers and sisters;
collateral blood relatives through the fourth civil degree, including first cousins;
step-parents and stepchildren;
parents-in-law and children-in-law;
an adopting parent and adopted child;
specified surviving spouses and adopted relatives;
an adopted child and a legitimate child of the adopter;
adopted children of the same adopter; or
parties where one killed that person’s own spouse or the other party’s spouse with the intention of marrying the other.

Bigamous marriages and an absent spouse

A person generally cannot marry while a prior marriage remains in force. Article 41 provides a narrow exception where the prior spouse has been absent for four consecutive years—or two years under specified circumstances involving danger of death—the present spouse has a well-founded belief that the absentee is dead, and a court has issued a declaration of presumptive death before the subsequent marriage.

Mere disappearance, loss of communication, migration or a belief that the prior spouse has died is insufficient. The statutory judicial proceeding must occur before remarriage.

Standing in bigamy-based nullity cases is unusually technical. In Quirit-Figarido v. Figarido, the Supreme Court en banc held that the aggrieved or injured innocent spouse of either marriage may seek nullity of the subsequent bigamous marriage, while an offending spouse who knowingly contracted it lacks standing. Anyone facing this issue should obtain case-specific advice before filing.

Grounds for annulment of a voidable marriage

Article 45 permits annulment only for the following causes existing when the marriage was celebrated:

Lack of required parental consent. The protected party was at least 18 but below 21, and the marriage occurred without the required consent. Free cohabitation after turning 21 may ratify the marriage.
Unsoundness of mind. Either party was of unsound mind, subject to rules on who may sue and whether the marriage was later ratified by free cohabitation after recovery.
Fraud affecting consent. Article 46 limits this 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 pre-existing drug addiction, habitual alcoholism, homosexuality or lesbianism.
These are the statute’s specific categories. Other misrepresentations about character, health, rank, wealth or chastity are not Article 46 fraud.
Force, intimidation or undue influence used to obtain consent.
Physical incapacity to consummate the marriage with the other spouse, where the incapacity continues and appears incurable. Infertility alone is not this ground.
A serious sexually transmissible disease that appears incurable.

For fraud, force, intimidation and undue influence, voluntarily continuing to live together as spouses after discovering the fraud or after the coercion has ceased may bar annulment.

Filing deadlines for annulment

The deadline depends on the ground:

Ground	Who may file and deadline
No parental consent	The protected 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 who did not know of the condition; a relative, guardian or person with legal charge of the spouse of unsound mind before either spouse dies; or that spouse during a lucid interval or after regaining sanity, subject to non-ratification
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 disappeared or ceased
Incapacity to consummate	The injured spouse within five years after the marriage
Serious and apparently incurable STI	The injured spouse within five years after the marriage

Do not wait until the last month. Determining the correct starting date, collecting records, establishing venue and preparing a legally sufficient petition take time.

By contrast, Article 39 as amended by Republic Act No. 8533 provides that an action or defense for declaration of absolute nullity does not prescribe. Lack of prescription does not relax the rules on standing or proof, and delay may still make witnesses and records difficult to obtain.

How the court process works

1. Identify the ground before preparing the petition

Begin with the facts and documents, not a preferred legal label. A lawyer should determine:

which law governed when the marriage was celebrated;
whether the alleged defect existed at that time;
whether the facts support nullity, annulment, legal separation, recognition of a foreign judgment or another remedy;
who has standing;
whether an annulment deadline is running; and
what orders are needed for children, support or property.

2. File in the correct Family Court

The case belongs in the Regional Trial Court branch designated as a Family Court under the Family Courts Act.

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

The petition must state complete facts, identify the common children and their ages, describe the governing property regime and properties involved, be verified, and include a certification against forum shopping. The petitioner must personally sign the verification and certification; counsel or an attorney-in-fact cannot sign them in the petitioner’s place.

Current Rule 13-A filing requirements apply to annulment and nullity cases. An initiatory petition is filed in paper form personally, by registered mail or by accredited courier, followed by email transmission of the petition and accompanying documents in PDF format to the court within 24 hours after completing the primary filing. Subsequent pleadings are generally filed and served electronically. The designated court email address, payment instructions and copy requirements should be confirmed with the proper Office of the Clerk of Court before filing. See A.M. No. 25-01-13-SC.

The petitioner must also serve the Office of the Solicitor General and the appropriate city or provincial prosecutor within the period required by the special rule and submit proof of service.

3. Obtain valid service of summons

The respondent must receive summons under the Rules of Court. If diligent efforts cannot locate the respondent, the court may authorize publication once a week for two consecutive weeks in a newspaper of general circulation, together with additional service measures.

Ordinarily, the respondent has 15 days from service of summons to file a verified answer. If summons was served by publication, the period is 30 days from the last publication.

Failure to answer does not place the respondent in default and does not automatically win the case for the petitioner.

4. State investigation and mandatory pre-trial

If no answer is filed or the answer raises no genuine issue, the court directs the public prosecutor to investigate possible collusion. The prosecutor represents the State’s interest in preventing fabricated or suppressed evidence.

Pre-trial is mandatory. The parties must disclose their evidence and witnesses and personally attend unless the court accepts a legally sufficient excuse. Mediation may address matters the law permits the parties to settle, such as some property, support or parenting arrangements. The validity of the marriage and the existence of a ground cannot be compromised.

5. Trial and proof

The judge personally conducts the trial on the marriage ground. The petitioner must prove the ground even if the respondent agrees, fails to appear or does not oppose the case. A judgment on the pleadings, summary judgment or confession of judgment is not allowed.

The public prosecutor may cross-examine witnesses and challenge questionable evidence. The Office of the Solicitor General may also participate, seek reconsideration or appeal.

6. Decision, finality and appeal

A favorable trial-court decision is not immediately a license to remarry. Under the special rule, the decision ordinarily becomes final 15 days after notice if no motion for reconsideration, motion for new trial or appeal is filed.

A party who intends to appeal must first file a timely motion for reconsideration or new trial. Appellate proceedings can materially extend the case.

7. Property settlement, decree and registration

Depending on the ground and applicable property regime, the court may need to address:

liquidation, partition and distribution of property;
creditors;
custody and support of common children;
delivery of the children’s presumptive legitimes where legally required; and
registration of the judgment, entry of judgment and property partition.

The court issues the decree only after the applicable requirements have been completed. The judgment and related instruments must be recorded in the relevant civil registries and registries of property. Article 53 permits remarriage only after compliance with Article 52.

After registration, verify with the local civil registrar where the marriage was recorded that the documents were forwarded to the Philippine Statistics Authority. The PSA identifies supporting records such as the court decree, certificate of finality, certificate of registration and related marriage-certificate copies. See the PSA’s official guidance on an annotated Certificate of Marriage.

Do not rely solely on an oral statement that the case is “finished.” Obtain and preserve certified copies of the decision, entry or certificate of finality, decree, registration records and annotated PSA Certificate of Marriage.

Children, custody and support

Nullity or annulment does not erase parenthood or end a child’s right to support.

While the case is pending, the court may issue provisional orders on:

custody;
child support;
appropriate visitation;
spousal support where legally available; and
administration of community or conjugal property.

The child’s moral and material welfare is the primary consideration. Parenting arrangements should not be used to pressure the other spouse into admitting a marriage ground or surrendering property rights.

The effect on a child’s legal status depends on the ground and timing. Article 54 expressly considers legitimate children conceived or born before a judgment of annulment or of Article 36 nullity becomes final and executory, as well as children of a subsequent marriage covered by Article 53. Other void marriages may produce different consequences. Obtain specific advice before making statements about legitimacy, surnames, inheritance or birth-record changes.

Property consequences are ground-specific

Do not assume that every asset will simply be divided equally.

Annulled marriages and different types of void marriages may be governed by different rules. Articles 50 and 51 apply in specified cases, while co-ownership rules under Articles 147 or 148 may govern some void unions. Good or bad faith, legal capacity to marry, actual contributions, care of the household, existing marriage settlements, prior marriages, creditors and property titles can change the result.

Preserve records for:

land, condominium units and vehicles;
loans, mortgages and credit cards;
businesses and shares;
bank, investment and retirement accounts;
insurance policies;
inheritances and donations;
major improvements to separately owned property;
assets transferred to relatives or third parties; and
household and childcare contributions.

Do not sell, conceal, encumber or transfer disputed property to defeat the other spouse or the children. Seek provisional relief if an asset is in immediate danger.

Evidence to preserve

The necessary evidence depends on the ground, but a useful file may include:

Civil-status and marriage records

PSA and local civil registrar copies of the marriage certificate;
marriage-license application and license records;
birth certificates showing the parties’ ages;
prior marriage certificates, judgments, death certificates or foreign civil-status records;
records concerning the solemnizing officer’s authority;
marriage settlements; and
proof of the parties’ addresses and length of residence for venue.

For psychological incapacity

a chronological account of conduct before and during the marriage;
names and contact information of people who observed the spouse before marriage;
contemporaneous letters, messages and emails;
medical, treatment or rehabilitation records lawfully obtainable;
police, barangay, employment, school or financial records connected to the alleged dysfunction;
evidence of repeated failures involving support, fidelity, household responsibilities or children; and
records showing whether the conduct was enduring rather than an isolated marital conflict.

For fraud, coercion or medical grounds

documents showing when the concealed fact was discovered;
medical records and qualified medical testimony;
messages, threats or witness accounts;
the relevant final criminal judgment, if Article 46 conviction-based fraud is alleged; and
proof of whether the spouses cohabited freely after the truth was known or the coercion ended.

For children and property

school, medical and childcare records;
proof of regular expenses and support payments;
income records;
titles, tax declarations and loan statements;
account statements and business records; and
an inventory of property and debts.

Keep originals and unaltered digital copies. Export electronic messages with dates and account information where possible. Do not hack an account, impersonate another person, secretly alter records or obtain protected medical or financial data unlawfully.

Common mistakes

Treating ordinary marital breakdown as automatic psychological incapacity.
Choosing “annulment” merely because it is the familiar term.
Filing an annulment after the statutory deadline.
Relying only on conduct that began after the wedding without evidence connecting it to a condition existing at the time of marriage.
Assuming an expert report guarantees an Article 36 judgment.
Fabricating messages, rehearsing false testimony or coordinating a sham case with the other spouse.
Giving an incomplete or false address to avoid serving the respondent.
Believing nonappearance by the respondent results in an automatic grant.
Asking the PSA to cancel the marriage record without first obtaining the required judicial judgment.
Treating a church decree as a civil decree.
Remarrying after receiving a favorable decision but before finality, issuance of the decree and completion of registration.
Ignoring custody, support, debts, property or creditor issues until after trial.
Trusting promises of a guaranteed result, fixed completion date or “package” without official receipts and a written professional-fee agreement.

Cost and duration

Philippine law does not establish one fixed total “annulment price” or guaranteed completion time. Possible expenses include court filing fees, legal fees, service of summons, publication when authorized, document certification, expert services when used, transcripts, property proceedings and civil-registry work.

Duration depends on the court’s docket, the difficulty of serving the respondent, the number of witnesses, whether the case is contested, property and custody issues, prosecutor and OSG participation, and any appeal.

Before engaging counsel, ask for a written agreement identifying professional fees, reimbursable expenses, payment stages and work excluded from the quote. Qualified indigent clients may seek assistance from the Public Attorney’s Office, subject to its applicable eligibility and merit rules. See the PAO services guidance.

When legal help is urgent

Seek immediate advice when:

an annulment deadline is approaching;
either spouse plans to remarry;
the respondent is leaving the country or cannot be located;
a child may be removed, hidden or taken abroad;
property is being sold, mortgaged, withdrawn or transferred;
a spouse has died and inheritance or estate proceedings are beginning;
immigration, citizenship or foreign-divorce issues are involved;
documents may be destroyed; or
there is violence, stalking, coercive control, threats or danger to a child.

A marital-status case is not a substitute for immediate protection. A person facing violence should prioritize safety, medical care and preservation of evidence and may approach the nearest police station or Women and Children Protection Desk, Barangay VAW Desk, social-welfare office or Family Court. Barangay, temporary and permanent protection orders may be available independently under the Anti-Violence Against Women and Their Children Act.

Other remedies may be more appropriate

Depending on the facts, the proper proceeding may instead be:

Legal separation, which allows spouses to live separately and affects property and inheritance but does not sever the marriage bond or permit remarriage.
Judicial recognition of a foreign divorce or foreign judgment, where Philippine law permits its effects to be recognized. This is a separate proceeding requiring proof of the foreign judgment and applicable foreign law.
Declaration of presumptive death before a contemplated subsequent marriage, if Article 41’s strict requirements are satisfied.
Divorce under the Code of Muslim Personal Laws, where that Code applies. See Presidential Decree No. 1083.
Independent proceedings for support, custody, protection orders or property administration, which may be pursued without waiting for a marital-status case when legally appropriate.

Frequently asked questions

Can the spouses jointly agree to an annulment?

They may agree on some lawful collateral matters, but they cannot agree that the marriage is invalid. The petitioner must prove a statutory ground, and the State participates to prevent collusion and fabricated evidence.

Is a psychologist required for Article 36?

No. Current Supreme Court doctrine does not make an expert diagnosis or personal examination indispensable. The evidence must still clearly and convincingly establish a grave, enduring and pre-existing psychological incapacity connected to essential marital obligations.

Is infidelity enough?

Not by itself. It may support legal separation or another claim and may form part of an Article 36 case, but only if the total evidence establishes the required pre-existing psychological incapacity.

What if the other spouse refuses to participate?

The case may continue after valid service, but there is no automatic default judgment. The petitioner must still prove the ground, and the prosecutor may investigate collusion and test the evidence.

Can a nullity case be filed at any time?

An action or defense for absolute nullity generally does not prescribe. Standing, venue, evidentiary and registration requirements still apply. Annulment has separate and strict deadlines.

Can I remarry as soon as the judge grants the petition?

No. Wait for finality, the required decree, property and children-related compliance where applicable, and proper registration under Articles 52 and 53. Obtain an annotated PSA Certificate of Marriage before making decisions based on a changed civil status.

Does a church annulment permit civil remarriage?

No. A church or religious decree does not itself change Philippine civil status. A civil court proceeding and the required registrations remain necessary.

Will the children become illegitimate?

Not automatically. Article 54 preserves legitimacy in specified annulment and Article 36 situations. The result in other void marriages depends on the applicable provisions and the child’s circumstances.

Can the marriage entry simply be corrected at the local civil registrar?

No. Administrative correction cannot replace a direct court action where the objective is to invalidate a marriage. The civil registry annotates the record only after the required judgment and registration documents are presented.

Is there a guaranteed cost or completion time?

No. Any promise of guaranteed approval or a fixed completion date should be treated cautiously. Cost and duration depend on service, evidence, court schedules, property and custody questions, and possible appeals.
