Yes. In the Philippines, an annulment or declaration of nullity case can proceed even if the other spouse refuses to participate, ignores the summons, does not file an answer, or does not attend hearings. But it does not become an automatic or “default” win. The court still has to be satisfied that the marriage is legally void or voidable, the respondent spouse was properly notified, there is no collusion, and the petitioner’s evidence is strong enough under Philippine law. (Lawphil)

Many people ask this because the other spouse has disappeared, migrated abroad, is hiding, refuses to sign anything, or says, “I will never agree to an annulment.” The important point is this: the other spouse’s consent is not required, but proper court procedure and evidence are required.

Annulment in the Philippines does not work like a mutual divorce

In ordinary conversation, Filipinos often use “annulment” to mean any court case that ends a marriage. Legally, there are two different remedies:

Common term people use	Proper legal remedy	Basic meaning
“Annulment”	Annulment of voidable marriage	The marriage was valid at first, but may be annulled because of a legal defect existing at the time of marriage.
“Annulment under psychological incapacity”	Declaration of nullity of marriage under Article 36	The marriage is considered void from the beginning because one or both spouses were psychologically incapacitated to comply with essential marital obligations.
“Void marriage”	Declaration of absolute nullity	The marriage was void from the start, such as bigamous marriage, no valid marriage license, or prohibited relationship.

The Family Code treats marriage as a legal status, not just a private contract. Article 1 describes marriage as a special contract and an inviolable social institution. That is why spouses cannot simply sign an agreement saying the marriage is over. The court must decide. (Supreme Court E-Library)

Can the case proceed if the other spouse does not answer?

Yes. Under the Supreme Court’s Rule on Declaration of Absolute Nullity of Void Marriages and Annulment of Voidable Marriages — A.M. No. 02-11-10-SC — the respondent spouse is given a period to file an answer after summons is served. If the respondent fails to answer, the court shall not declare the respondent in default. Instead, the court orders the public prosecutor to investigate whether the spouses are colluding. (Lawphil)

This is different from many ordinary civil cases, where failure to answer can lead to default. In annulment and nullity cases, the State has an interest in protecting marriage and preventing fake or agreed-upon annulments. So even if the respondent spouse disappears, the petitioner must still prove the ground.

In practical terms, the case may continue in this sequence:

The petition is filed in the proper Family Court.
Summons is served on the respondent spouse.
The respondent spouse does not answer or does not participate.
The court orders the public prosecutor to investigate possible collusion.
If the prosecutor reports no collusion, the court sets the case for pre-trial.
The petitioner presents evidence at trial.
The public prosecutor may intervene to prevent fabricated or suppressed evidence.
The judge decides whether the legal ground is proven.

Why the other spouse’s consent is not required

A Philippine annulment or nullity case is not granted because both spouses agree. It is granted only if the facts fit a legal ground under the Family Code.

Article 48 of the Family Code states that in all annulment and nullity cases, the court must order the prosecuting attorney or fiscal to appear for the State to prevent collusion and to make sure evidence is not fabricated or suppressed. The same article also says that no judgment can be based on a stipulation of facts or confession of judgment. (Supreme Court E-Library)

This means:

A spouse cannot simply “admit” psychological incapacity and expect the court to grant the case.
A written agreement between spouses is not enough.
A respondent’s silence is not enough.
The petitioner must still testify and present documents and witnesses.
The judge must independently evaluate the evidence.

So if the other spouse says, “I will not sign,” that does not stop the case. But if the petitioner says, “My spouse will sign anything,” that also does not guarantee approval.

Legal grounds still matter

The court can only grant the petition if one of the legal grounds is proven.

Grounds for declaration of absolute nullity

A marriage may be void from the beginning under provisions such as Articles 35, 36, 37, 38, 40, 41, 44, and 53 of the Family Code. Common examples include:

One party was below 18 at the time of marriage.
The solemnizing officer had no legal authority, subject to good-faith exceptions.
There was no valid marriage license, unless the marriage falls under a legal exemption.
The marriage was bigamous or polygamous.
The parties are within prohibited degrees of relationship.
One or both spouses were psychologically incapacitated under Article 36. (Supreme Court E-Library)

For Article 36 psychological incapacity, the Supreme Court in Tan-Andal v. Andal clarified that psychological incapacity is a legal concept, not strictly a medical illness. Expert testimony from a psychologist or psychiatrist may help, but it is not always mandatory. The petitioner must prove the incapacity by clear and convincing evidence, showing gravity, juridical antecedence, and incurability in the legal sense. (Supreme Court E-Library)

Grounds for annulment of voidable marriage

Article 45 of the Family Code lists grounds for annulment of a voidable marriage, including:

Lack of required parental consent for a party aged 18 but below 21 at the time of marriage.
Unsound mind.
Fraud.
Force, intimidation, or undue influence.
Physical incapacity to consummate the marriage that appears incurable.
Serious and incurable sexually transmissible disease. (Supreme Court E-Library)

Article 46 explains what counts as fraud, such as concealment of a serious sexually transmissible disease, drug addiction, habitual alcoholism, homosexuality or lesbianism existing at the time of marriage, or concealment by the wife that she was pregnant by another man at the time of marriage. (Supreme Court E-Library)

These grounds have specific filing periods under Article 47. This is one reason it is important to distinguish a true annulment case from a declaration of nullity case.

What if the other spouse cannot be found?

If the respondent spouse cannot be located at the address given, or the respondent’s whereabouts are unknown despite diligent inquiry, the court may allow service of summons by publication. Under A.M. No. 02-11-10-SC, publication may be ordered once a week for two consecutive weeks in a newspaper of general circulation in the Philippines, and a copy of the summons must also be sent to the respondent’s last known address by registered mail or another method the court considers sufficient. (Lawphil)

This step is often one of the biggest bottlenecks in cases where the other spouse is missing. Courts usually want to see genuine effort to locate the respondent, such as:

Last known home address
Workplace or business address
Contact details
Social media or email information, if relevant
Information from relatives or mutual acquaintances
Immigration or overseas address, if known
Returned mail, sheriff’s return, or other proof of attempted service

A petitioner should not falsely claim that the respondent cannot be found. If the court later discovers that the address was intentionally wrong or that the petitioner hid the respondent’s real location, the case may be delayed or dismissed.

What if the other spouse is abroad?

An annulment or nullity case may still proceed even if the respondent spouse is abroad. The key issue is still notice: the court must be satisfied that summons and court notices were served in a legally acceptable way.

For petitioners abroad, documents signed outside the Philippines often need proper authentication. The Supreme Court’s OCA Circular No. 284-2023 recognizes that an Affidavit of Residency executed by a petitioner temporarily residing abroad for employment, business, education, or another purpose, and authenticated by the appropriate Philippine Consulate, may be sufficient compliance with the residency requirement under the 2023 amended guidelines.

Foreign public documents may also need an apostille or consular authentication, depending on the country where the document was issued. For countries that are part of the Apostille Convention, an apostille generally replaces the old legalization process; for non-Apostille countries, consular legalization may still be required. (Apostille Philippines)

Practical examples:

A Filipino in Canada files a case in the Philippines while the respondent is in Dubai.
A foreign spouse returns to Europe and refuses to join the case.
An OFW spouse is served but ignores all notices.
The respondent has a known foreign address but refuses to receive mail.

In these situations, the case does not die just because the respondent is outside the Philippines. But defective service of summons can create serious delays and may expose the decision to challenge later.

Step-by-step process when the respondent spouse does not participate

1. Prepare the petition and evidence

The petition must allege the complete facts supporting the legal ground. It must also state the children of the parties, property regime, and properties involved. The petition must be verified and must include a certification against forum shopping signed personally by the petitioner, not merely by counsel or an attorney-in-fact. (Lawphil)

For Article 36 cases, the facts should describe the actual behavior and circumstances showing psychological incapacity. Generic statements like “we always fought,” “my spouse abandoned me,” or “we are incompatible” are usually not enough.

2. File in the proper Family Court

The case is filed in the Family Court of the proper province or city. Under A.M. No. 02-11-10-SC, venue is generally based on where the petitioner or respondent has resided for at least six months before filing, or where a non-resident respondent may be found in the Philippines. (Lawphil)

Family Courts are specialized courts created under Republic Act No. 8369, the Family Courts Act of 1997, which gave Family Courts jurisdiction over family-related cases, including annulment and declaration of nullity. (Supreme Court E-Library)

3. Serve copies on the OSG and public prosecutor

The petitioner must serve copies of the petition on the Office of the Solicitor General (OSG) and the Office of the City or Provincial Prosecutor within the required period and submit proof of service. Failure to comply may be a ground for dismissal. (Lawphil)

This is a common technical mistake. The OSG and prosecutor are not optional participants. They represent the State’s interest in the marital status of the parties.

4. Serve summons on the respondent spouse

The sheriff or authorized officer attempts to serve summons. If personal service is not possible, substituted service, publication, or other court-approved modes may become necessary depending on the facts.

If the respondent is genuinely missing, the petitioner may have to file a motion asking the court to allow service by publication.

5. Wait for the respondent’s answer period

The respondent generally has 15 days from service of summons to file an answer, or 30 days from the last issue of publication if summons is served by publication. The answer must be verified by the respondent personally. (Lawphil)

If no answer is filed, the case does not automatically end in the petitioner’s favor.

6. Collusion investigation by the public prosecutor

If no answer is filed, or if the answer does not raise a real issue, the court orders the public prosecutor to investigate whether the parties are colluding. The prosecutor submits a report to the court. If the prosecutor finds collusion, the court may hear the matter and dismiss the petition if convinced that collusion exists. If no collusion is found, the court sets pre-trial. (Lawphil)

7. Pre-trial

Pre-trial is mandatory. Even if the respondent did not answer, notice of pre-trial must still be sent to the respondent. If summons was by publication and the respondent did not answer, notice is sent to the respondent’s last known address. (Lawphil)

If the petitioner fails to appear personally at pre-trial without a valid excuse, the case may be dismissed.

8. Trial and presentation of evidence

The judge personally conducts the trial. The petitioner and witnesses present testimony and documents. The grounds for annulment or nullity must be proven. No judgment on the pleadings, summary judgment, or confession of judgment is allowed. (Lawphil)

In an uncontested case, the trial may be simpler because there is no active opposition from the respondent. But it still requires competent evidence.

9. Decision, finality, decree, and registration

If the court grants the petition, the decision does not immediately mean the parties can remarry. The decision must become final, the required property and children-related matters must be resolved when applicable, and the decree must be issued and registered.

Under the Family Code, the judgment, partition and distribution of properties, and delivery of presumptive legitimes must be recorded in the proper civil registries and registries of property; otherwise, they will not affect third persons. Article 53 also states that either former spouse may marry again only after compliance with the registration requirements, otherwise the subsequent marriage is void. (Supreme Court E-Library)

The Supreme Court rule also requires registration of the decree with the civil registry where the marriage was registered, the civil registry where the Family Court is located, and the PSA. (Lawphil)

Documents commonly needed

Document	Why it matters
PSA marriage certificate	Proves the recorded marriage and details needed for annotation later.
PSA birth certificates of children	Needed for custody, support, legitimacy, and presumptive legitime issues.
Valid IDs and proof of residence	Used for venue and identity.
Marriage license, marriage application, or local civil registry records	Important in no-license, defective license, or irregular marriage cases.
Psychological report or expert evaluation, if used	Often helpful in Article 36 cases, though not always legally mandatory after Tan-Andal.
Judicial affidavits of petitioner and witnesses	Used to present direct testimony efficiently.
Proof of respondent’s address or whereabouts	Needed for proper service of summons.
Foreign documents, if any	May require apostille, consular authentication, and certified English translation.
Property documents	Needed if there are conjugal or community assets to liquidate.
Prior court orders or foreign divorce decree, if applicable	May affect whether annulment is the correct remedy.

Usual timelines when the other spouse does not participate

Timelines vary heavily by court, location, judge, prosecutor availability, service of summons, publication, evidence, and OSG action. A realistic range is often one and a half to four years, with some cases shorter and some much longer.

Stage	Common source of delay
Filing and raffle	Court docket congestion and compliance review
Summons	Respondent cannot be found, lives abroad, or avoids service
Publication	Preparing motion, court approval, newspaper schedule, proof of publication
Collusion investigation	Prosecutor workload and scheduling
Pre-trial	Notices, availability of parties, incomplete pre-trial briefs
Trial	Witness schedules, judicial affidavits, expert testimony
Decision and finality	Waiting period, possible motion for reconsideration or appeal
Decree and PSA annotation	Registration with LCR, court documents, PSA processing

Electronic filing now also matters. The Supreme Court expanded Rule 13-A to include annulment and nullity cases, meaning pleadings, motions, and other papers in these cases are now covered by electronic filing and service, except where a different mode is required. (Supreme Court E-Library)

Common scenarios

“My spouse refuses to sign anything.”

The case can still proceed. A signature from the respondent spouse is not required for the court to decide. What matters is valid service of summons and proof of the legal ground.

“My spouse received the summons but ignored it.”

The court will not declare the respondent in default. The prosecutor must investigate collusion. If there is no collusion, the case can proceed to pre-trial and trial.

“My spouse is abroad and does not want to come home.”

The case may still proceed, but service of summons must be handled properly. If the respondent has a known foreign address, the petitioner should not pretend the respondent is missing.

“My spouse is missing and I do not know where he or she lives.”

The petitioner must show diligent efforts to locate the respondent. The court may allow publication if the legal requirements are met.

“We both agree to separate. Can we make it faster?”

Agreement may help settle custody, support, or property issues that the law allows parties to settle, but it cannot replace proof of the ground for annulment or nullity. The court cannot grant the case based only on agreement.

“Can I remarry after the judge grants the petition?”

Not immediately. Wait for finality, issuance of the decree, and proper registration with the civil registry and PSA. Remarrying too early can create serious civil and criminal consequences. Bigamy is penalized under Article 349 of the Revised Penal Code when a person contracts a second or subsequent marriage before the former marriage has been legally dissolved or before an absent spouse has been declared presumptively dead in proper proceedings. (Supreme Court E-Library)

Foreign spouses and foreign divorce

If the marriage is between a Filipino and a foreigner, annulment may not always be the best or only path. If a valid foreign divorce has already been obtained and it capacitates the foreign spouse to remarry, the Filipino spouse may be able to file a Philippine case for recognition of foreign divorce instead of an annulment.

Article 26, paragraph 2 of the Family Code allows the Filipino spouse to have capacity to remarry under Philippine law when a marriage between a Filipino and a foreigner is followed by a valid foreign divorce obtained abroad that capacitates the alien spouse to remarry. (Supreme Court E-Library)

In Republic v. Manalo, the Supreme Court held that Article 26 may apply even if the Filipino spouse initiated the foreign divorce, as long as the divorce is valid abroad and capacitates the foreign spouse to remarry. (Supreme Court E-Library)

This is important for Filipinos abroad because a recognition-of-foreign-divorce case may be more appropriate than an Article 36 nullity case when there is already a valid foreign divorce decree.

After the case: PSA annotation is still required

A final court decision is not the end of the paperwork. The marriage record must be updated.

The PSA’s guidance on annotation of annulment or declaration of nullity instructs parties to coordinate with the Local Civil Registry Office where the Certificate of Marriage was registered and verify whether supporting documents were forwarded to PSA. If not, certified true copies of documents such as the court decree, certificate of finality, certificate of registration, certificate of authenticity, and annotated marriage certificate may be required for processing. (Philippine Statistics Authority)

In real life, this stage can take months. Delays happen when:

The court has not issued the decree.
The Local Civil Registry has not transmitted documents to PSA.
PSA requires verification of the court documents.
The marriage was registered in a different city or municipality.
Names, dates, or registry numbers do not match.

Until the PSA and civil registry records are properly updated, parties may still encounter problems with remarriage, passports, visas, property transactions, and government records.

Frequently Asked Questions

Can annulment proceed if my spouse refuses to attend hearings?

Yes. If your spouse was properly served and still refuses to attend, the case may proceed. The court will not grant the petition automatically, but it may allow the petitioner to present evidence with the prosecutor participating for the State.

Will the court approve my annulment because my spouse did not answer?

No. Failure to answer is not enough. The court must still find that the legal ground was proven by evidence. In annulment and nullity cases, there is no ordinary default judgment.

What happens if my spouse cannot be found?

The court may allow summons by publication if you show that the respondent’s whereabouts are unknown and cannot be discovered despite diligent inquiry. The court will usually require proof of efforts to locate the respondent.

Can my spouse stop the annulment by not signing?

No. A respondent spouse cannot stop the case merely by refusing to sign. But the respondent may delay the case by challenging summons, filing an answer, opposing evidence, or appealing if there are legal grounds.

Is an uncontested annulment faster?

Usually, it can be faster than a heavily contested case, but it is not instant. The court must still go through summons, collusion investigation, pre-trial, trial, decision, finality, decree, and registration.

Do I still need witnesses if my spouse does not participate?

Usually, yes. The petitioner’s testimony is normally not enough by itself in many cases, especially Article 36 cases. Corroborating witnesses, documents, and sometimes expert evidence can help establish the facts.

Can a foreign spouse ignore a Philippine annulment case?

A foreign spouse may choose not to participate, but the Philippine court must still require proper notice. If service is defective, the decision may be vulnerable to challenge.

Can I file in the Philippines while living abroad?

Yes, but venue, residency proof, document signing, authentication, and hearing arrangements must be handled carefully. Petitioners abroad often need consular acknowledgment, apostilled documents, or authenticated affidavits depending on the document and country involved.

Is barangay conciliation required before annulment?

No barangay can annul a marriage. Annulment and declaration of nullity are Family Court cases involving civil status. Barangay proceedings may be relevant to separate issues like minor disputes, but they cannot dissolve or void a marriage.

When am I legally single again?

You are not fully cleared for remarriage just because you received a favorable decision. Wait for finality, decree, registration with the proper civil registries, PSA annotation, and compliance with Articles 52 and 53 of the Family Code.

Key Takeaways

An annulment or nullity case can proceed without the other spouse participating, as long as summons and notices are properly handled.
The respondent spouse’s refusal to sign or attend does not automatically stop the case.
The court will not declare the respondent in default in the usual civil-case sense.
The public prosecutor must investigate possible collusion when no answer is filed or no real issue is raised.
The petitioner must still prove a valid ground under the Family Code.
Proper service of summons is critical, especially if the respondent is missing or abroad.
A favorable decision is not enough for remarriage; finality, decree, registration, and PSA annotation still matter.
For Filipino-foreigner marriages with a valid foreign divorce, recognition of foreign divorce may be the more appropriate remedy than annulment.
