Quick answer

“Annulment” and “declaration of nullity” are different court remedies under Philippine law:

Declaration of absolute nullity applies when the marriage was legally void from the beginning.
Annulment applies when the marriage was valid until a court sets it aside because of a defect existing when it was celebrated.

Neither remedy is a general “no-fault” divorce. Separation, incompatibility, infidelity, abandonment, or both spouses wanting to end the marriage does not, by itself, establish a legal ground. The proper remedy depends on what existed at the time of marriage and what admissible evidence can prove it.

Even when a marriage is void, obtain the proper final court judgment and complete the required civil-registry and property registrations before remarrying. A private agreement, church annulment, or long separation does not change civil status.

Annulment versus declaration of nullity

Question	Declaration of nullity	Annulment
Status of marriage	Void from the beginning	Valid until annulled
Main legal basis	Articles 35–38 and related provisions of the Family Code	Article 45 of the Family Code
Filing deadline	Generally does not prescribe	Strict deadlines apply
Typical examples	Underage marriage, absence of a required marriage license, bigamy, incest, psychological incapacity	Lack of required parental consent, specified fraud, force, unsound mind, incapacity to consummate, serious incurable STI
Is mutual consent enough?	No	No
Is a court case required before remarriage?	Yes	Yes

The governing provisions are in the Family Code of the Philippines, as amended by Executive Order No. 227 and other laws.

When a marriage may be declared void

Marriages void under Article 35

Subject to the exact facts and statutory exceptions, a marriage is void from the beginning when:

Either party was below 18 years old, even if a parent or guardian consented.
The person who solemnized the marriage had no legal authority, unless either or both parties believed in good faith that the solemnizing officer had authority.
There was no marriage license, unless the marriage lawfully fell within a license exemption.
The marriage was bigamous or polygamous and did not qualify as a valid subsequent marriage under Article 41.
One party was mistaken about the identity of the other contracting party.
A subsequent marriage is void under Article 53 because mandatory post-judgment requirements from an earlier annulment or nullity case were not completed.

A certification that no marriage license record can be found may be important, but it is not always the end of the inquiry. The court must still determine whether a license existed or whether an exemption applied. Exemptions include certain deathbed, remote-place, ship or aircraft, military-zone, consular, Muslim or indigenous-community marriages, and qualifying marriages after at least five years of cohabitation without a legal impediment. Each exemption has its own conditions.

Psychological incapacity under Article 36

A marriage is void if, at the time it was celebrated, either or both spouses were psychologically incapacitated to comply with essential marital obligations, even if the incapacity became evident only later.

Under the Supreme Court’s controlling interpretation in Tan-Andal v. Andal, G.R. No. 196359:

Psychological incapacity is a legal concept, not necessarily a medically diagnosed disorder.
It must be serious enough to show genuine inability—not mere refusal, difficulty, neglect, immaturity, or unwillingness—to perform essential marital obligations.
It must have existed when the marriage was celebrated, although later conduct may reveal it.
“Incurability” is understood in the legal sense: the personality structure is so enduring and resistant to change that the spouse cannot fulfill the obligations of that particular marriage.
The ground must be proved by clear and convincing evidence.
A psychologist or psychiatrist is not legally required in every case. Testimony from relatives, friends, or others who knew the spouse before and during the marriage may be sufficient if it credibly establishes the required facts.

Infidelity, violence, substance misuse, abandonment, irresponsibility, or financial neglect is not automatically psychological incapacity. Such conduct may be relevant only when the total evidence connects it to a grave, enduring incapacity that already existed when the parties married.

Incestuous marriages under Article 37

The following are void regardless of whether the relationship is legitimate or illegitimate:

Marriages between ascendants and descendants of any degree.
Marriages between brothers and sisters, whether of full or half blood.

Marriages void for public-policy reasons under Article 38

These include marriages between:

Collateral blood relatives up to the fourth civil degree.
Stepparents and stepchildren.
Parents-in-law and children-in-law.
An adopting parent and an adopted child.
The surviving spouse of an adopting parent and the adopted child.
The surviving spouse of an adopted child and the adopter.
An adopted child and a legitimate child of the adopter.
Adopted children of the same adopter.
Parties where one, intending to marry the other, killed that person’s spouse or their own spouse.

Grounds for annulment

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

Lack of required parental consent. One party was 18 but below 21 and married without the consent required by law.
Unsound mind. Either party was of unsound mind, unless the other spouse knew of that condition.
Fraud. Consent was obtained through one of the specific forms of fraud recognized by Article 46.
Force, intimidation, or undue influence. Consent was not freely given.
Physical incapacity to consummate the marriage. The incapacity continues and appears incurable.
Serious and apparently incurable sexually transmissible disease. The disease existed when the marriage was celebrated.

Physical incapacity to consummate is not the same as infertility. Inability to have children, standing alone, is not this annulment ground.

What counts as fraud

Article 46 limits fraud to:

Concealment of a previous conviction by final judgment 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 when the marriage was celebrated, regardless of its nature.
Concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing when the marriage was celebrated.

Misrepresentations about character, health, rank, fortune, or chastity generally do not constitute Article 46 fraud.

Concealing an STI as fraud is distinct from the separate Article 45 ground requiring a serious, apparently incurable STI. Because the grounds and filing periods are applied differently, the petition must identify the correct theory.

Annulment deadlines

An annulment action can be lost through delay or, for certain grounds, through free cohabitation after the defect becomes known or ends.

Ground	Who may file and deadline
Lack of parental consent	The affected spouse: within five years after turning 21. A parent, guardian, or person with legal charge may file before that spouse turns 21. Free cohabitation after age 21 may ratify the marriage.
Unsound 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 the death of either party; or the affected spouse during a lucid interval or after regaining sanity. Free cohabitation after recovery may bar annulment.
Fraud	The injured party: within five years after discovering the fraud. Free cohabitation with full knowledge may ratify the marriage.
Force, intimidation, or undue influence	The injured party: within five years after the force, intimidation, or undue influence ceased. Free cohabitation afterward may ratify the marriage.
Physical incapacity to consummate	The injured party: within five years after the marriage was celebrated.
Serious, apparently incurable STI	The injured party: within five years after the marriage was celebrated.

An action or defense to declare a void marriage absolutely null generally does not prescribe. Article 39’s former limitation for psychological-incapacity cases was removed by Republic Act No. 8533.

Do not wait when an annulment deadline may be running. The date of marriage, the parties’ ages, the date a fact was discovered, and any later cohabitation can determine whether a case remains available.

What is not enough by itself

The following do not independently create an annulment or nullity ground:

A long period of separation.
“Irreconcilable differences” or incompatibility.
Loss of love.
Infidelity or abandonment arising only after marriage.
Domestic violence, without proof of a statutory ground existing at marriage.
A spouse’s refusal to sign papers.
Both spouses agreeing that the marriage should end.
A barangay settlement or notarized separation agreement.
A religious or church annulment.
A fabricated or purchased civil-registry annotation.

These circumstances can still matter as evidence, support another legal remedy, or require immediate protective action. They simply do not allow a court to invent a ground outside the Family Code.

Who files and where

Under the special procedural rule, a petition for declaration of nullity may be filed solely by the husband or wife. The persons allowed to seek annulment depend on the ground and are identified in the deadline table above.

The petition must be filed in the proper Regional Trial Court designated as a Family Court:

Where either the petitioner or respondent has resided for at least six months immediately before filing, at the petitioner’s choice; or
If the respondent is a nonresident, where the respondent may be found in the Philippines.

Residence is a factual venue requirement. Keep documents showing the actual address and length of residence. The Supreme Court Court Locator can help identify the appropriate court, but the branch and filing instructions should be confirmed with the Office of the Clerk of Court.

How the case generally proceeds

The controlling procedure is the Supreme Court’s Rule on Declaration of Absolute Nullity and Annulment, A.M. No. 02-11-10-SC.

1. Legal and factual assessment

A lawyer should first identify the precise statutory ground, deadline, proper venue, necessary parties, property regime, children’s issues, and available evidence. The ground should follow the facts—not the label the parties prefer.

2. Preparation and filing of the petition

The petition must state the complete material facts, identify the common children and their ages, describe the property regime and relevant properties, and request any necessary provisional relief.

It must be verified and accompanied by a certification against forum shopping personally signed by the petitioner. It cannot ordinarily be filed solely through an attorney-in-fact. A petitioner abroad must comply with the authentication or current consular requirements applicable to the verification and certification.

Nullity and annulment cases are now covered by mandatory electronic filing and service under Rule 13-A. Counsel must follow the current electronic-filing rules, the court’s official electronic address or system, and any required treatment of original or paper documents. See A.M. No. 25-01-13-SC and the Judiciary’s electronic-filing information.

The special rule also requires timely service on the Office of the Solicitor General and the appropriate city or provincial prosecutor. Noncompliance with filing, verification, certification, or service requirements can lead to dismissal.

3. Summons and the respondent’s answer

The respondent ordinarily has 15 days from service of summons to file a personally verified answer. If service is authorized by publication because the respondent cannot be located after diligent inquiry, the special rule provides 30 days from the last publication issue.

A respondent who does not answer is not declared in default. The court still requires proof of the ground.

4. Prosecutor’s investigation and State participation

If no answer is filed or the answer raises no real issue, the court orders the public prosecutor to investigate whether the parties are colluding. The prosecutor represents the State’s interest in preventing fabricated or suppressed evidence.

The spouses’ mutual wish to end the marriage, the respondent’s non-opposition, or testimony from the respondent’s relatives does not by itself prove collusion. Collusion requires evidence of an agreement to fabricate a ground or suppress a valid defense. This was clarified in Republic v. Ramoran-Wong, G.R. No. 276986.

That ruling does not permit an agreed annulment. The legal ground must still be independently proved.

5. Mandatory pre-trial and possible provisional orders

Pre-trial is mandatory, and personal appearance is normally required. The petitioner’s unjustified failure to appear can cause dismissal.

The parties may resolve matters the law allows them to settle, such as certain property, custody, support, and visitation arrangements. They cannot compromise the validity of the marriage, civil status, future support, jurisdiction, or future legitime.

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

Spousal support.
Custody and support of common children.
Visitation.
Administration of community or conjugal property.
Other matters requiring urgent protection.

6. Trial

The judge must receive and evaluate evidence proving the asserted ground. A judgment cannot rest merely on admissions, a confession of judgment, an agreed statement that the marriage is invalid, or the respondent’s silence.

The court may limit public access to protect privacy, and the special rule restricts access to case records.

7. Decision, finality, and appeal

A decision does not become final immediately upon issuance. Under the special rule, a motion for reconsideration or new trial must be filed within 15 days from notice if a party intends to challenge the judgment. Such a motion is a precondition to an appeal, and the notice of appeal must be filed within 15 days from notice of its denial.

Because electronic service can affect when notice is deemed received, any adverse decision should be referred to counsel immediately.

8. Liquidation, registration, and decree

A favorable decision is not the last administrative step. Depending on the case, the parties may need to complete:

Liquidation, partition, and distribution of property.
Registration of the approved partition with the proper Registry of Deeds.
Delivery of the children’s presumptive legitimes when required.
Registration of the entry of judgment and decree with the civil registries concerned and the Philippine Statistics Authority.
Publication of the decree when summons was served by publication.

The prevailing party must report registration of the decree to the court within 30 days after receiving it. The registered decree is the best evidence of the annulment or declaration of nullity and serves as notice to third persons.

Do not plan a new marriage until counsel has confirmed finality and full compliance with Articles 40, 52, and 53 and the applicable registration requirements.

Evidence to collect and preserve

The evidence must match the specific ground. Useful materials may include:

Core civil documents

PSA marriage certificate and, where material, the local civil-registry record.
Birth certificates of the spouses and common children.
Prior marriage certificates, death certificates, annulment or nullity judgments, and civil-registry annotations.
Marriage-license application, license, exemption affidavit, and records from the issuing local civil registrar.
Proof of the petitioner’s or respondent’s six-month residence.

Evidence concerning consent or capacity

Contemporaneous messages, letters, emails, diaries, photographs, and recordings lawfully obtained.
Medical records, diagnoses, laboratory results, and treating professionals’ testimony.
Police, barangay, hospital, school, employment, rehabilitation, or court records.
Witnesses with first-hand knowledge of conduct before and during the marriage.
Proof showing when fraud was discovered or when force or intimidation ended.

Evidence for psychological incapacity

Prepare a detailed chronology covering the spouse’s history before marriage, courtship, early married life, recurring behavior, its effect on essential marital obligations, and why the conduct reflects inability rather than ordinary unwillingness.

Witnesses who knew the spouse before marriage can be particularly important. An expert assessment may strengthen some cases, but it cannot replace facts, and it is not mandatory in every case.

Property and children’s records

Land titles, tax declarations, deeds, vehicle registrations, corporate records, bank statements, loan documents, insurance policies, and inventories.
Proof of income, school and medical expenses, caregiving arrangements, and the children’s present needs.
Prenuptial agreements and prior property settlements.

Preserve original files and complete message threads. Do not alter screenshots, coach witnesses, access another person’s account without authority, conceal assets, or manufacture evidence.

Effects on property, children, and inheritance

The consequences depend on the ground, the property regime, good or bad faith, existing agreements, and prior proceedings.

For annulled marriages and marriages declared void under Articles 36 or 53, Articles 50 and 51 generally require liquidation and application of the consequences referenced in Article 43. These may include partition, forfeiture affecting a spouse in bad faith, custody and support orders, and delivery of children’s presumptive legitimes.

Other void unions may be governed by the special co-ownership rules in Articles 147 or 148 rather than the ordinary community-property rules. Title documents alone may not resolve ownership where common funds, exclusive property, bad faith, or third-party rights are involved.

Children conceived or born before a judgment annulling the marriage becomes final remain legitimate. Children conceived or born before a final Article 36 nullity judgment, and children of a subsequent marriage covered by Article 53, are likewise treated as legitimate under Article 54. The status of children from other void marriages must be assessed under the applicable Family Code provisions.

A decree does not erase parental obligations. Support, custody, visitation, inheritance, and the children’s welfare remain separate legal concerns.

Cost and duration

There is no reliable fixed cost or guaranteed completion date.

Expenses may include filing and other court fees, service or publication, civil-registry documents, transcripts, professional fees, expert work where used, property proceedings, and registration. Court fees can also depend on the relief requested and the property involved.

Timing varies with service of summons, court calendars, prosecutor review, the number of witnesses, disputed custody or property, publication, appeals, and post-judgment registration. Be cautious of anyone guaranteeing approval, a fixed completion date, or a “package” that avoids court appearances or evidence.

People who may qualify for free legal assistance can inquire with the Public Attorney’s Office or an Integrated Bar of the Philippines chapter. Eligibility, conflicts, and case acceptance must still be assessed.

Common mistakes to avoid

Calling every case “annulment” without identifying the legal ground.
Missing an Article 47 deadline.
Assuming five or more years of separation automatically ends the marriage.
Treating adultery, violence, or abandonment as automatic Article 36 proof.
Filing in a convenient city without satisfying the six-month residence requirement.
Using only events after the wedding without showing the defect existed at marriage.
Assuming a missing marriage-license record conclusively proves nullity without checking exemptions and surrounding records.
Omitting property, children, prior marriages, or material facts from the petition.
Believing an uncontested case will be granted automatically.
Entering a secret arrangement to fabricate testimony or suppress evidence.
Treating a church decree as a civil annulment.
Remarrying after receiving a decision but before finality, decree issuance, and required registrations.
Paying a fixer for a supposed court order or PSA annotation.

Authenticity can be checked with the issuing court, the relevant local civil registrar, and the PSA. A civil-registry annotation is not a substitute for an authentic final judgment and decree.

When legal help is urgent

Consult a family-law lawyer promptly when:

An annulment deadline may expire.
The respondent is missing, abroad, or deliberately evading service.
A spouse threatens to sell, hide, mortgage, or transfer property.
Children may be removed, concealed, harmed, or denied necessary support.
A party dies while the case is pending; a death before entry of judgment can terminate the personal nullity or annulment proceeding.
You receive a decision, order, summons, or electronic notice carrying a short deadline.
You are considering remarriage and the decree or registrations are incomplete.
There is a prior marriage, disputed foreign divorce, or questionable marriage-license record.

If there is violence, stalking, coercive control, sexual abuse, or an immediate threat, do not wait for the marriage case. Contact law enforcement and seek advice about barangay, temporary, or permanent protection orders under the Anti-Violence Against Women and Their Children Act. A nullity or annulment case does not replace urgent safety, criminal, custody, or protection-order remedies.

Frequently asked questions

Can we obtain an annulment if we both agree?

Agreement is not a legal ground. However, under Republic v. Ramoran-Wong, mutually wanting the marriage to end or choosing not to oppose the petition is not automatically collusion. The petitioner must still prove a statutory ground with genuine evidence.

Is a psychological evaluation mandatory?

No. Tan-Andal confirms that psychological incapacity is a legal concept and that expert testimony is not indispensable. An evaluation may still be useful depending on the evidence and litigation strategy.

Does cheating automatically make a marriage void?

No. Infidelity may support a factual pattern, but it is not by itself an Article 36 ground. The evidence must prove a grave and enduring incapacity existing at the time of marriage.

Does years of separation make us legally single?

No. Separation does not terminate civil status, regardless of duration.

What if my spouse refuses to participate?

The case can proceed after valid service, but the respondent is not declared in default and the petition is not automatically granted. The court will still examine the evidence and possible collusion.

What if my spouse cannot be located?

After documented diligent efforts, the court may authorize summons by publication once a week for two consecutive weeks, together with service to the last known address or another method the court considers sufficient.

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

No. Wait for finality, entry of judgment, issuance and registration of the decree, and completion of any required property and children’s-legitime steps. Obtain legal confirmation before applying for another marriage license.

Does a church annulment change my PSA record?

No. Religious proceedings and civil court proceedings are separate. A church decree does not by itself terminate a civil marriage or authorize civil remarriage.

What if there is already a foreign divorce?

Judicial recognition of a foreign divorce is a different remedy. Where Article 26 applies, the Philippine court generally must be shown the valid foreign divorce and the relevant foreign law. Citizenship at the time of divorce and the decree’s legal effect are important. See Republic v. Manalo and Republic v. Orbecido III.

Are the rules the same for Muslim marriages?

Not necessarily. Marriage and divorce governed by the Code of Muslim Personal Laws, Presidential Decree No. 1083, may involve different substantive rules and Shari’a court jurisdiction.
