Quick answer

Philippine law provides two different court remedies:

Declaration of absolute nullity applies when the marriage was legally void from the beginning.
Annulment applies when the marriage was valid until a court annulled it because a specific defect existed when it was celebrated.

Separation, incompatibility, infidelity, abandonment, abuse, or loss of love does not automatically make a marriage void or voidable. Those facts may support another remedy—or help prove psychological incapacity—but the petitioner must establish a ground expressly recognized by the Family Code.

A spouse remains married for civil purposes while the case is pending. Even a void marriage requires a final court judgment before its nullity may be invoked for remarriage. Do not remarry merely because the spouses have separated, signed an agreement, obtained a church decree, or received an RTC decision that is not yet final, registered, and implemented as required by law.

Nullity and annulment are not the same

Issue	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid unless and until annulled
Source of grounds	Articles 35–38 and other applicable Family Code provisions	Article 45
Filing deadline	The action or defense generally does not prescribe	Strict deadlines apply, usually five years from the event specified by law
Effect of later cohabitation	Usually does not validate a void marriage	Free cohabitation after the defect ends may bar certain grounds
Remarriage	Requires a final judgment and compliance with registration and property requirements	Requires a final judgment, decree, and compliance with post-judgment requirements

Republic Act No. 8533 removed the former prescriptive limitation affecting certain Article 36 cases, so an action or defense for absolute nullity does not prescribe. That does not mean delay is harmless: witnesses may die, records may disappear, and the case must be terminated if a party dies before entry of judgment under the governing court rule. See Republic Act No. 8533.

When a marriage may be declared void

Marriages void under Article 35

Article 35 identifies the following marriages as void from the beginning:

A marriage contracted by a person below 18, even with parental consent.
A marriage solemnized by someone without legal authority, unless either or both parties believed in good faith that the solemnizing officer had authority.
A marriage without a valid marriage license, unless a Family Code exemption genuinely applied.
A bigamous or polygamous marriage not covered by Article 41.
A marriage contracted because one party was mistaken about the other party’s identity.
A subsequent marriage void under Article 53.

A missing PSA record, clerical defect, irregular marriage certificate, or certification that a document cannot be found does not by itself settle whether a marriage was valid. The court examines the legal requirements and the evidence surrounding the celebration. A petition to cancel or correct a civil-registry entry under Rule 108 cannot be used to bypass a direct nullity case in the Family Court. The Supreme Court recently reaffirmed this distinction in Spouses Ferreros v. Republic, G.R. No. 276941.

Psychological incapacity under Article 36

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

Psychological incapacity is a legal concept, not simply a psychiatric diagnosis. Under Tan-Andal v. Andal, G.R. No. 196359, the evidence must show:

Clear acts of dysfunctionality undermining the marriage or family;
A durable aspect of the spouse’s personality structure;
A genuinely serious psychic cause, not mere unwillingness, neglect, difficulty, ill will, mood changes, or occasional outbursts;
An incapacity that already existed when the marriage was celebrated, although its manifestations may have appeared later; and
An enduring and persistent inability, in the legal sense, to understand and comply with essential marital obligations in relation to the particular spouse.

The petitioner must prove psychological incapacity by clear and convincing evidence. A psychologist or psychiatrist is not legally indispensable, and the allegedly incapacitated spouse need not personally submit to examination. Expert evidence may nevertheless be useful when reliable and properly connected to the facts.

Infidelity, violence, abandonment, addiction, financial irresponsibility, or refusal to provide support is not automatically psychological incapacity. Such conduct may be relevant only if the totality of evidence shows a grave, enduring incapacity rooted in a personality structure that existed when the parties married.

Incestuous and public-policy marriages

Article 37 declares marriages between ascendants and descendants, and between full- or half-blood siblings, void from the beginning.

Article 38 also invalidates specified marriages for public policy, including certain marriages between relatives up to the fourth civil degree, step-parents and stepchildren, parents-in-law and children-in-law, adopters and adopted children, and parties where one killed a spouse to marry the other.

Other Family Code provisions govern particular subsequent marriages, presumptive-death situations, bigamy, bad faith, and failures to complete required registration and property steps after an earlier judgment. These cases are document-sensitive and should not be assessed from the marriage certificate alone.

Grounds for annulment

Article 45 allows annulment only when one of these causes existed when the marriage was celebrated:

Lack of required parental consent. One spouse was at least 18 but below 21 and married without the consent required by law.
Unsoundness of mind. Either party was of unsound mind, subject to the statutory qualifications on who may sue and later free cohabitation.
Fraud affecting consent.
Force, intimidation, or undue influence affecting consent.
Physical incapacity to consummate the marriage. The incapacity must continue and appear incurable. Infertility alone is not the same as inability to consummate.
Serious, apparently incurable sexually transmissible disease.

What legally counts as fraud

Article 46 limits fraud to specified concealment or nondisclosure:

Nondisclosure of a previous final conviction for a crime involving moral turpitude;
Concealment by a wife that she was pregnant by another man when the marriage was celebrated;
Concealment of a sexually transmissible 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 treats concealment, not sexual orientation by itself, as the relevant fraud. Other lies about character, health, rank, wealth, or chastity do not constitute Article 46 fraud unless they fall within an expressly recognized category.

Annulment filing deadlines

These periods are strict and can be affected by who files and whether the parties freely cohabited after the defect ended.

Ground	Who may file	Deadline
No parental consent for a spouse aged 18–20	The spouse concerned	Within five years after turning 21, unless that spouse freely cohabited with the other after turning 21
Same ground	Parent, guardian, or person having legal charge	Before the spouse turns 21
Unsoundness of mind	The sane spouse without knowledge; a qualified relative, guardian, or person having legal charge; or the affected spouse during a lucid interval or after regaining reason	The period and right to sue depend on the petitioner; qualified representatives must act before either spouse dies
Fraud	Injured party	Within five years after discovering the fraud, provided the injured party did not freely cohabit after learning the truth
Force, intimidation, or undue influence	Injured party	Within five years after it disappeared or ceased, provided there was no later free cohabitation
Physical incapacity to consummate	Injured party	Within five years after the marriage
Serious, apparently incurable STI	Injured party	Within five years after the marriage

If a possible annulment ground is approaching a deadline, obtain legal advice immediately. Do not assume that informal separation, negotiations, barangay proceedings, or an agreement with the other spouse pauses the period.

Who may file

Under the Supreme Court Rule on Nullity and Annulment, A.M. No. 02-11-10-SC, a petition for absolute nullity may generally be filed only by the husband or wife. Annulment standing depends on the particular Article 45 ground and Article 47.

Standing becomes more complicated when:

The challenged marriage is bigamous;
A spouse from an earlier subsisting marriage is the injured party;
One of the parties has died;
Heirs are disputing status in an estate case; or
A foreign judgment is involved.

In Quirit-Figarido v. Republic, G.R. No. 259520, the Supreme Court discussed the standing of an innocent or injured spouse in relation to a bigamous subsequent marriage. A participant who knowingly contracted the bigamous marriage cannot simply assume that Article 35 automatically gives that person standing to obtain a decree and remarry.

Marriage validity may sometimes be determined incidentally in an estate, criminal, property, or status case. That is different from a direct petition seeking a decree of nullity and the capacity to remarry.

Where and how the case is filed

Family Courts have exclusive original jurisdiction over annulment and nullity cases under the Family Courts Act, Republic Act No. 8369. Where no separately organized Family Court exists, the case is handled by the RTC branch designated to hear family cases.

The petition must be filed in 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 rule permits filing where the respondent may be found in the Philippines, at the petitioner’s election.

The petition must:

State the complete facts supporting the legal ground;
Identify the common children and their ages;
Identify the applicable property regime and properties involved;
Be verified and accompanied by a certification against forum shopping;
Be signed personally by the petitioner, not merely by counsel or an attorney-in-fact; and
Comply with service requirements involving the Office of the Solicitor General and the city or provincial prosecutor.

The special rule specifies six copies and requires service of the petition on the OSG and prosecutor, with proof submitted within five days from filing. Because lower-court filing practices now include electronic-copy requirements, counsel should confirm the current branch instructions. The Supreme Court’s lower-court electronic-filing guidance treats electronic transmission as the primary mode for later civil submissions but excepts initiatory pleadings; initial petitions remain subject to Rule 13 and pertinent court directions.

What happens after filing

1. Summons and answer

The respondent must be served with summons. An answer is generally due within 15 days from service. If the respondent cannot be located after diligent inquiry, the court may authorize publication once a week for two consecutive weeks, together with other forms of notice. An answer following publication is due within 30 days from the last publication.

The respondent’s failure to answer does not result in default or automatic approval.

2. State participation and collusion inquiry

If no answer is filed or the answer does not raise a genuine issue, the court directs the public prosecutor to investigate whether the spouses are colluding. The prosecutor represents the State’s interest in preventing fabricated or suppressed evidence.

A spouse cannot obtain annulment or nullity through an agreed statement of facts, confession of judgment, or private settlement. Civil status and marriage validity cannot be compromised.

3. Mandatory pre-trial

Both parties are generally required to appear personally at mandatory pre-trial. The parties must identify their claims, disputed issues, documents, witnesses, and expert evidence. A petitioner’s unjustified failure to appear may lead to dismissal.

Mediation may address lawful collateral matters, such as appropriate property or parenting arrangements. The parties cannot mediate their way into an agreed declaration that the marriage is invalid.

4. Trial

The judge personally receives the evidence on the ground for annulment or nullity. No judgment on the pleadings, summary judgment, or confession of judgment is allowed.

Family proceedings receive privacy protections. The court may exclude persons without a direct interest and restrict access to the records when justified.

5. Decision, reconsideration, and appeal

If the petition is granted, the decision is served on the parties, prosecutor, and Solicitor General. It generally becomes final after 15 days from notice if no timely motion or appeal prevents finality.

A party wishing to appeal must first file a motion for reconsideration or new trial within 15 days from notice of judgment. A notice of appeal is due within 15 days from notice of the denial. These are short, technical deadlines; obtain advice immediately upon receiving an adverse decision.

6. Property, children, registration, and decree

A favorable decision is not the final administrative step. Depending on the case, the court must address or complete:

Liquidation, partition, and distribution of property;
Notice to creditors;
Custody and support of common children;
Delivery of the children’s presumptive legitimes;
Registration of the entry of judgment in the required local civil registries;
Registration of an approved property partition with the proper Registry of Deeds; and
Issuance and registration of the decree.

The prevailing party must register the decree in the required civil registries and report compliance to the court within 30 days from receipt. The marriage record is ordinarily annotated, not erased. PSA advises first verifying with the Local Civil Registry Office that the decree, certificate of finality, certificate of registration, and related documents have been forwarded before requesting an annotated Certificate of Marriage. See the PSA annotation guidance.

Do not plan a new marriage until counsel has confirmed finality, issuance and registration of the decree, completion of applicable Article 52 requirements, and proper annotation.

Effects on children, support, and property

Children

Annulment or nullity does not end either parent’s duty to support a child. Custody is decided according to the child’s welfare, not as a reward for the spouse who wins the marriage case.

Children conceived or born before the final judgment of annulment remain legitimate. Article 54 also preserves the legitimacy of children conceived or born before the final judgment in an Article 36 case, as well as children covered by Article 53. The status of children from marriages void on other grounds may differ and must be determined under the applicable Family Code provisions and the child’s records.

Property

There is no universal “automatic 50-50” outcome. The result depends on:

The marriage settlement, if any;
Whether the marriage was void or voidable;
The spouses’ legal capacity to marry each other;
Their good or bad faith;
The property regime or co-ownership rules that apply;
The source and date of acquisition of each asset;
Contributions, debts, and creditor rights; and
Previous property judgments or agreements approved by a court.

Do not sell, hide, transfer, mortgage, or withdraw disputed property to defeat the other spouse or the children. The court may issue provisional orders on support, custody, visitation, and administration of community or conjugal property while the case is pending.

Evidence to preserve

Start with a dated chronology: courtship, marriage, residences, children, major incidents, discovery of the alleged defect, separation, and later cohabitation, if any.

Preserve:

PSA and local civil-registry copies of the marriage record;
Birth certificates of the spouses and children;
Marriage-license records, applications, affidavits, and parental-consent documents;
Earlier marriage certificates, judgments, decrees, and certificates of finality where bigamy is alleged;
Proof of residence for venue;
Prenuptial agreements and marriage settlements;
Titles, deeds, tax declarations, loan records, bank statements, insurance policies, business records, and inventories;
Original letters, emails, messages, photographs, and electronic files with dates and metadata;
Medical, treatment, rehabilitation, police, or employment records lawfully available to you;
Proof of when fraud was discovered or force ceased;
Names and contact details of witnesses with firsthand knowledge; and
For Article 36, evidence of a consistent pattern before and during the marriage, including witnesses who knew the spouse before the wedding.

Keep originals and make secure backups. Do not edit screenshots, coach witnesses, create evidence, access another person’s account without authority, or secretly intercept communications. Ask counsel before recording private conversations or trying to obtain confidential medical or financial records.

Common mistakes to avoid

Calling every marriage case “annulment” without identifying the correct legal ground.
Treating infidelity, abandonment, abuse, or incompatibility as automatic Article 36 proof.
Assuming a church annulment changes civil status.
Assuming a missing PSA record proves there was no valid marriage.
Filing a civil-registry correction case instead of the required direct Family Court action.
Continuing to live freely as spouses after discovering fraud or after force has ceased without first understanding the possible effect on annulment.
Missing an Article 47 deadline while attempting informal settlement.
Giving an incomplete property list or omitting children from the petition.
Failing to appear at pre-trial or obey court orders.
Believing the respondent’s absence guarantees approval.
Paying a fixer or anyone promising a guaranteed result.
Remarrying after an RTC decision but before finality, decree issuance, registration, and compliance with Articles 52 and 53.

Costs and duration

No law guarantees a fixed completion date or total price. The actual duration depends on service of summons, publication, court calendars, prosecutor participation, disputed evidence, expert witnesses, property proceedings, motions, and appeals.

Possible expenses include:

Official filing and docket fees assessed by the clerk of court;
Sheriff, service, and publication expenses;
Certified civil-registry and court records;
Lawyer’s professional fees;
Psychological or psychiatric assessment and testimony, if used;
Transcripts, registration, and property-related charges; and
Appeal expenses, if necessary.

Request a written engagement stating what professional fees cover and which expenses are separate. Pay official court charges only through authorized channels and keep receipts.

A person unable to afford private counsel may ask the Public Attorney’s Office about assistance, subject to its indigency, merit, conflict, and other eligibility rules. IBP legal-aid offices and accredited law-school legal clinics may also be available.

When help is urgent

Seek prompt legal advice when:

An annulment deadline may expire;
The other spouse is preparing to remarry, leave the country, conceal assets, or transfer property;
A child has been taken, threatened, denied support, or placed at risk;
You receive summons, a decision, or an order with a stated deadline;
The respondent’s location is unknown and publication may be necessary;
A party is seriously ill or has died;
The case involves an earlier marriage, foreign divorce, foreign spouse, or foreign judgment; or
You are being pressured to sign an affidavit, property waiver, or custody agreement.

If there is violence, stalking, coercion, or an immediate threat, safety should come before the marriage case. Annulment proceedings are not a substitute for police assistance, criminal remedies, or protection orders. Republic Act No. 9262 provides Barangay, Temporary, and Permanent Protection Orders for covered violence against women and their children. The Philippine Commission on Women’s guidance and your Barangay VAW Desk can help explain available protection.

Frequently asked questions

Can spouses obtain annulment simply because both agree?

No. The legal ground must be independently proved. The prosecutor and the State participate to prevent collusion and fabricated evidence.

Is a psychologist required in an Article 36 case?

No. Tan-Andal holds that psychological incapacity need not be medically diagnosed or proved exclusively by an expert. The totality and quality of the evidence still matter, and expert testimony may be useful in a particular case.

Can the case proceed if the respondent refuses to participate?

Potentially, yes. The respondent is not declared in default, but the court may proceed after valid service, publication where authorized, prosecutor participation, and proof of the ground.

Does a church annulment permit civil remarriage?

No. A religious decree does not by itself change Philippine civil status. A proper civil judgment and compliance with post-judgment requirements are still necessary.

Can I remarry immediately after receiving a favorable RTC decision?

No. Confirm finality, entry of judgment, completion of applicable property and presumptive-legitime requirements, issuance and registration of the decree, and civil-registry annotation first.

Does nullity automatically make all children illegitimate?

No. The result depends on the ground. Children covered by Article 54—including children conceived or born before the final judgment in annulment and Article 36 cases—remain legitimate. Support obligations continue regardless.

Is a foreign divorce the same as annulment?

No. Recognition of a foreign divorce is a separate remedy requiring proof of the foreign decree and applicable foreign law. Its availability depends on citizenship and other facts. Muslim marriages and divorces covered by the Code of Muslim Personal Laws also follow a distinct legal framework.

Can a court remove the marriage certificate from the civil registry?

Ordinarily, the final judgment and decree are registered and the marriage record is annotated. A Rule 108 correction or cancellation petition cannot substitute for a direct nullity or annulment case when marriage validity is the real issue.

Is there a guaranteed timetable or guaranteed result?

No. Any promise of guaranteed approval, a predetermined judge, or payment to “speed up” the result is a serious warning sign.
