Quick answer

Annulment and declaration of nullity are different court proceedings:

Declaration of absolute nullity applies when the marriage was void from the beginning—for example, because a required marriage license was absent without a lawful exemption, a prior marriage was still subsisting, the parties were within prohibited degrees of relationship, or a spouse had psychological incapacity under Article 36.
Annulment applies to a marriage that was valid until annulled because a specific defect existed when it was celebrated—for example, qualifying fraud, lack of required parental consent, force, unsoundness of mind, incurable incapacity to consummate the marriage, or a serious and apparently incurable sexually transmissible disease.

Separation, incompatibility, abandonment, infidelity, violence, substance abuse, or simply falling out of love does not automatically establish either case. Such conduct matters only if it proves a ground recognized by law.

A civil marriage remains on record unless the proper court grants relief and the final judgment and decree are registered. An agreement between spouses, a notarized document, a barangay settlement, or a church annulment cannot by itself end the civil marriage. Do not marry someone else until all judicial and registration requirements have been completed.

Annulment and nullity are not interchangeable

Issue	Declaration of nullity	Annulment
Legal character of marriage	Void from the beginning	Valid unless and until annulled
Source of grounds	Primarily Articles 35–38, 41, 44 and 53 of the Family Code	Article 45 of the Family Code
Filing period	The action or defense generally does not prescribe	Strict filing periods apply
Proof required	Facts establishing the particular defect or ground	Facts establishing an Article 45 ground that existed at the time of marriage
Effect on children	Depends on the ground; special rules protect children covered by Articles 36 and 53	Children conceived or born before the annulment judgment becomes final are legitimate
Need for a court case	Yes, particularly to change civil status and before remarriage	Yes

Neither remedy is the same as legal separation. Legal separation may permit spouses to live separately and may dissolve their property regime, but it does not sever the marriage bond and does not allow remarriage.

Recognition of a foreign divorce is also a distinct proceeding. It may be relevant when a marriage involved a foreign spouse and a valid divorce was obtained abroad, but the foreign judgment and applicable foreign law ordinarily must be proved in a Philippine court.

When a marriage may be declared void

Under the Family Code of the Philippines, marriages that may be void from the beginning include the following.

A party was below 18

A marriage contracted by a person below 18 is void even if a parent or guardian consented.

This differs from the annulment ground involving a party who was at least 18 but below 21 and married without the required parental consent under the law then applicable.

The solemnizing officer lacked authority

The marriage is generally void if the person who solemnized it had no legal authority. An exception may apply if either or both parties believed in good faith that the solemnizing officer was authorized.

There was no marriage license and no lawful exemption

A marriage celebrated without a valid license is generally void unless it fell within a statutory license exemption. Whether an exemption actually applied depends on the documents and facts existing when the marriage was celebrated.

A missing PSA record alone does not necessarily prove that no license was issued. The relevant local civil registrar’s records, the marriage certificate, the license application and any claimed exemption should be examined.

The marriage was bigamous or polygamous

A later marriage is generally void when a previous marriage was still subsisting. Article 41 provides a narrow exception involving an absent spouse, the required period of absence, a well-founded belief of death, and a judicial declaration of presumptive death obtained before the later marriage.

Even if someone believes the first marriage was defective, Article 40 requires a final judicial judgment declaring it void before remarriage. Remarrying without that judgment can create civil-status problems and possible criminal exposure for bigamy.

Mistake concerned the other party’s identity

The statutory ground is a mistake as to the identity of the person married—not merely a mistake about that person’s character, finances, social status or intentions.

Psychological incapacity existed at the time of marriage

Article 36 covers a spouse who, when the marriage was celebrated, was psychologically incapacitated to comply with essential marital obligations, even if the incapacity became apparent only later.

The Supreme Court’s controlling framework in Tan-Andal v. Andal treats psychological incapacity as a legal concept, not necessarily a medically diagnosed illness. The evidence must clearly and convincingly establish:

a genuinely serious psychic cause;
an enduring or persistent personality structure that makes compliance—not merely willingness—impossible in relation to the spouse;
clear acts of dysfunctionality affecting essential marital or parental obligations; and
juridical antecedence, meaning the incapacity existed when the marriage was celebrated, although it may have manifested more clearly afterward.

A psychologist or psychiatrist is not automatically required. Ordinary witnesses who knew the spouse before and during the marriage may supply important evidence. An expert assessment can still be useful in an appropriate case, but an unsupported diagnosis or a report based only on one spouse’s accusations does not guarantee success.

Psychological incapacity is not established by ordinary incompatibility, occasional outbursts, irresponsibility, refusal, neglect, ill will or difficulty in performing marital duties. Abandonment, infidelity, violence, addiction or financial irresponsibility may be relevant manifestations only when the totality of reliable evidence connects them to a serious, enduring incapacity already present at the time of marriage.

Either spouse may bring an Article 36 petition; the allegedly incapacitated spouse is not automatically barred from filing.

The parties were within prohibited relationships

Void marriages include:

marriages between ascendants and descendants of any degree;
marriages between full- or half-blood siblings;
marriages between collateral blood relatives up to the fourth civil degree; and
the other relationships specifically prohibited by Articles 37 and 38, including certain adoptive and affinity relationships.

A marriage is also void under Article 38 when one party, intending to marry the other, killed that person’s spouse or their own spouse.

A later marriage violated post-judgment requirements

A subsequent marriage can be void under Article 53 when a former spouse remarries without completing the registration and related requirements under Article 52 following an earlier annulment or declaration of nullity.

Time limit for nullity cases

Under Article 39, as amended by Republic Act No. 8533, an action or defense for declaration of absolute nullity does not prescribe.

Delay can nevertheless make a case much harder. Witnesses may die or forget details, records may be lost, and property or inheritance disputes may become more complicated.

When a marriage may be annulled

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

Lack of required parental consent

This applies when a party was at least 18 but below 21 and married without the consent then required from a parent, guardian or person exercising substitute parental authority.

The affected party must file within five years after reaching 21. A parent, guardian or person having legal charge may file before the party reaches 21. Free cohabitation as spouses after reaching 21 can prevent annulment on this ground.

Unsoundness of mind

The case may be brought by the sane spouse who did not know of the condition, by specified persons legally responsible for the spouse of unsound mind, or by that spouse during a lucid interval or after regaining sanity.

The precise right to sue and the effect of later free cohabitation depend on who files and what occurred after sanity was regained.

Fraud affecting consent

For annulment, “fraud” has a narrow statutory meaning. Article 46 identifies:

nondisclosure of a previous final conviction for a crime involving moral turpitude;
concealment by the wife that, when the marriage occurred, she was pregnant by another man;
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.

Other deceit about character, health, rank, wealth or chastity is not Article 46 fraud.

The injured party must file within five years after discovering the fraud. Freely living with the other spouse after learning the truth may amount to ratification and defeat the ground.

Force, intimidation or undue influence

The injured party must file within five years after the force, intimidation or undue influence disappeared or ceased. Free cohabitation after the pressure ended may bar the action.

Physical incapacity to consummate the marriage

The incapacity must have existed at the time of marriage, must concern consummation with the other spouse, and must continue and appear incurable. The injured party must file within five years after the marriage.

Serious and apparently incurable sexually transmissible disease

The disease must have existed when the marriage was celebrated, be serious, and appear incurable. The injured party must file within five years after the marriage.

Who may file

The Supreme Court’s special procedural rule, A.M. No. 02-11-10-SC, generally provides that a petition for declaration of absolute nullity may be filed by the husband or wife. An annulment petition may be filed only by the person authorized for the particular ground and within the applicable period.

Third parties ordinarily cannot use a matrimonial petition simply to attack another person’s marriage. Cases involving a prior spouse, competing marriages, death, inheritance or estate proceedings can raise special standing and procedural questions. Obtain individual advice before filing or choosing the proper remedy.

If a party dies before entry of judgment, the matrimonial case is closed and terminated, without prejudice to issues that may properly be resolved in estate proceedings. If death occurs after entry of judgment, the judgment binds the parties and their successors in the settlement of the estate.

Where and how the case is filed

The petition is filed in the Family Court—or the Regional Trial Court acting as a Family Court where applicable. Family Courts have exclusive original jurisdiction over these cases under the Family Courts Act of 1997.

Venue is generally 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. Courts may require documentary proof of genuine residence; using a convenient or fabricated address risks dismissal and other consequences.

The petition must:

state the complete material facts supporting the legal ground;
identify the common children and their ages;
describe the governing property regime and relevant properties;
be personally verified by the petitioner;
include a certification against forum shopping; and
comply with service, copy, filing-fee and current court-submission requirements.

The special rule requires service of a copy on the Office of the Solicitor General and the city or provincial prosecutor within five days after filing, with proof submitted to the court within the same period. Failure to meet the rule’s formal requirements may result in immediate dismissal.

A petitioner abroad must still personally execute the verification and certification in the form permitted by current rules. Counsel should verify the applicable authentication or apostille requirements and the court’s current filing arrangements.

What normally happens after filing

1. Summons and answer

The respondent must be properly served with summons. An answer is generally due within 15 days from service. If service is authorized by publication because the respondent cannot be located after diligent inquiry, the answer is due within 30 days from the last publication.

Publication is not an automatic shortcut. It requires leave of court and proof of diligent efforts to locate the respondent.

Failure to answer does not result in an ordinary default judgment. Marital status cannot be changed merely because the other spouse does not participate.

2. Collusion investigation

When no answer is filed or the answer does not genuinely dispute the petition, the court directs the public prosecutor to investigate possible collusion. The State participates to help prevent fabricated or suppressed evidence.

The spouses cannot obtain a decree simply by agreeing that the marriage should be annulled or declared void. A confession, admission or stipulation alone is insufficient.

3. Mandatory pre-trial

Pre-trial is mandatory. The parties generally must appear personally and file compliant pre-trial briefs. Evidence and witnesses must be identified in accordance with the court’s orders.

The parties may settle lawful collateral matters, such as certain property arrangements, but they cannot compromise the validity of the marriage, civil status, future support, court jurisdiction jurisdiction or future legitime.

4. Trial and proof

The petitioner must prove the statutory ground. No judgment on the pleadings, summary judgment or confession of judgment is allowed.

The length of the case depends on service of summons, court workload, contested facts, the number of witnesses, expert or documentary evidence, property issues, and any appeal. No lawyer can responsibly guarantee a fixed completion date or a favorable result.

5. Decision, finality and appeal

Under the special rule, a granting decision generally becomes final after 15 days from notice if no authorized post-judgment remedy or appeal is filed. A party wishing to appeal must first timely file a motion for reconsideration or new trial; the applicable appeal period then runs from notice of its denial.

Deadlines are strict. Have counsel calculate them from the actual date and manner of service rather than relying on an estimate.

6. Property settlement and issuance of the decree

A favorable decision is not always the final administrative step. Depending on the case, the parties must complete:

liquidation, partition and distribution of property;
notice to affected creditors;
custody and support orders;
delivery of the common children’s presumptive legitimes;
registration of the entry of judgment;
registration of the approved property partition with the appropriate Registry of Deeds; and
issuance and registration of the decree.

The prevailing party must cause the decree to be registered in the relevant civil registries and with the national civil-registration authority, and report compliance to the court within the period required by the rule. Where summons was served by publication, additional publication requirements apply.

When can a former spouse remarry?

Do not remarry merely because:

the trial court announced a favorable ruling;
a copy of the decision was received;
the other spouse agreed not to appeal;
the spouses have long lived separately; or
the PSA marriage certificate has not yet been annotated.

Before remarriage, obtain and verify the required final court records, decree, civil-registry registrations, property-related compliance where applicable, and an updated annotated civil-registry record. Article 53 provides that failure to comply with Article 52 before remarriage can make the subsequent marriage void.

Remarrying prematurely may also expose a person to a bigamy complaint. Article 40 requires a final judgment declaring the previous marriage void before its nullity may be invoked for remarriage.

Children, custody and support

A nullity or annulment case does not erase parental obligations. The court may issue provisional and final orders on custody, visitation and support, always considering the children’s welfare.

Children conceived or born before a judgment under Article 36 becomes final and executory remain legitimate. Children of a subsequent marriage covered by Article 53 are likewise legitimate. Children conceived or born before an annulment judgment becomes final are also treated as legitimate. The status of children in other void-marriage situations depends on the particular ground and applicable provisions of the Family Code.

Support is separate from access or visitation. A parent generally cannot withhold necessary child support solely because the other parent interferes with visits, nor use the child as leverage in the matrimonial case.

Property and debts

The property consequences depend on matters such as:

the ground on which the marriage is annulled or declared void;
whether either party acted in good or bad faith;
the applicable property regime;
marriage settlements;
when and how each asset was acquired;
existing debts, liens and creditors’ rights; and
whether the parties were legally married or merely co-owners.

A decree does not automatically mean that every asset will be divided equally. The court may have to liquidate the absolute community or conjugal partnership, apply co-ownership rules, forfeit net profits in cases of bad faith, preserve creditors’ rights and deliver the children’s presumptive legitimes.

Do not sell, conceal, transfer or encumber disputed property to defeat the other spouse or creditors. Preserve titles and financial records and seek provisional relief if assets are being dissipated.

Evidence to preserve

Collect evidence before records disappear, but obtain and store it lawfully. Useful materials may include:

PSA and local civil-registry copies of the marriage certificate;
the marriage-license application, license and related local civil registrar certifications;
birth certificates of the spouses and common children;
records of previous marriages, judgments, decrees and civil-registry annotations;
proof of actual residence for venue;
contemporaneous messages, emails, letters, photographs and diaries;
school, employment, medical, rehabilitation or police records lawfully available to you;
protection orders, incident reports and court records;
names and contact details of witnesses who knew the spouses before and during the marriage;
property titles, tax declarations, deeds, loan records and marriage settlements;
bank, business and investment records lawfully accessible to you;
receipts and proof of household or child-related expenses; and
a dated chronology distinguishing events before marriage, at marriage and afterward.

For an Article 36 case, evidence from before the wedding is especially important because the incapacity must have existed when the marriage was celebrated. Avoid secretly accessing password-protected accounts, impersonating another person, fabricating screenshots or coaching witnesses.

Practical steps before filing

Identify the possible legal ground. Describe facts and dates first; do not begin by forcing the story into “annulment” or “psychological incapacity.”
Check the filing deadline immediately. Annulment periods vary by ground and may already be running.
Obtain civil-registry records. Compare PSA copies with records from the local civil registrar that issued the license or registered the marriage.
Prepare a truthful chronology. Include unfavorable facts, later cohabitation, prior cases and any agreements. They may affect ratification, credibility, venue or forum shopping.
List children, assets, debts and urgent needs. Consider provisional support, custody, visitation or property-administration orders.
Consult a Philippine family-law practitioner. Ask for a written explanation of the proposed ground, evidence gaps, professional fees and likely out-of-pocket expenses.
If unable to afford private counsel, ask the Public Attorney’s Office. PAO provides legal assistance subject to its current indigency, merit and conflict-of-interest rules. See the official PAO services and qualification guidance.
Verify completion after judgment. Secure the entry of judgment, decree, registration proofs and updated civil-registry records before treating the process as complete.

Common mistakes

Treating ordinary incompatibility as psychological incapacity.
Assuming adultery, abandonment or abuse automatically makes the marriage void.
Using “fraud” in its everyday sense instead of Article 46’s limited definition.
Filing an annulment case after the statutory period expired.
Choosing a court using a temporary or fictitious address.
Relying only on one spouse’s admissions or on an agreement to end the marriage.
Presenting a generic psychological report without facts showing gravity, persistence and juridical antecedence.
Hiding a prior case, marriage, child, asset or debt.
Assuming an absent respondent guarantees victory.
Believing a church annulment changes civil status automatically.
Remarrying after a favorable decision but before finality, issuance of the decree and required registrations.
Paying someone who promises a guaranteed result, a “non-appearance annulment,” fabricated evidence or special access to a judge.

When legal help is urgent

Seek prompt legal assistance when:

an annulment filing period may soon expire;
you have received summons, a court order, a pre-trial notice or an adverse decision;
the other spouse is threatening to sell, hide or transfer assets;
a child has been taken, concealed or placed at immediate risk;
the respondent is abroad or cannot be located;
either spouse has remarried or plans to remarry;
a spouse has died and marital status affects inheritance;
there are conflicting marriage records or prior judgments;
immigration, citizenship, benefits or property rights depend on marital status; or
there is violence, stalking, coercion or an immediate threat.

A matrimonial case is not a substitute for emergency protection. If violence is occurring, prioritize physical safety and ask counsel or the appropriate authorities about protection orders and other remedies under the Anti-Violence Against Women and Their Children Act or other applicable laws.

Frequently asked questions

Can both spouses simply agree to an annulment?

No. They may agree on lawful collateral matters, but they cannot create a ground or determine their own civil status. The petitioner must prove a statutory ground, and the State participates to prevent collusion and fabricated evidence.

Is infidelity enough?

Not by itself. Infidelity may support a different remedy, such as legal separation, and may be relevant evidence in an Article 36 case only if it forms part of proof of a serious, enduring psychological incapacity existing at the time of marriage.

Is a psychological evaluation mandatory?

Not in every Article 36 case. Tan-Andal confirms that expert evidence is not indispensable. The total evidence must still clearly and convincingly establish the legal elements, and an expert may remain useful depending on the facts.

Can the case proceed if the other spouse refuses to participate?

Possibly. Proper service remains essential, and the petitioner must still prove the case. The respondent’s silence does not amount to consent and does not produce a default decree.

What if the spouse cannot be found?

After diligent efforts, counsel may ask the court to authorize service by publication and other required means. Publication involves specific contents, timing and mailing or alternative-service requirements.

Does long separation automatically end the marriage?

No. Even decades of separation do not by themselves annul or nullify a marriage.

Can a church annulment be used?

A church decision does not change Philippine civil status by itself. In an Article 36 case, a canonical decision may be presented as persuasive evidence, but it does not bind the civil court.

Is there a standard price or completion time?

No reliable universal figure exists. Filing fees, publication, transcripts, professional services, evaluations, property proceedings and appeals vary. Court workload and disputed facts also affect duration. Be cautious of guaranteed prices tied to a guaranteed outcome.

Does a decree automatically change the PSA marriage record?

No. The judgment, entry of judgment and decree must undergo the required registrations. Obtain an updated annotated record afterward and check that names, dates and case details are accurate.

Can I remarry as soon as the decision becomes final?

Not necessarily. Complete the decree, property and civil-registration requirements applicable to the case first. Have counsel and the local civil registrar confirm the documentary requirements before setting a wedding date.
