Introduction

A common concern in Philippine annulment and nullity cases is what happens when the other spouse refuses to participate. Many petitioners fear that the case cannot move forward unless both spouses appear in court. Others worry that the absent spouse can indefinitely delay the case simply by ignoring notices, refusing to file an answer, or not attending hearings.

In Philippine practice, the refusal of a spouse to attend hearings does not automatically stop an annulment, declaration of nullity, or legal separation case. Marriage cases are not ordinary private disputes, and the court has an independent duty to determine the truth of the allegations. However, the non-appearance of one spouse does not give that spouse an absolute veto over the proceedings.

The case may continue, provided the rules on jurisdiction, service of summons, notice, due process, and presentation of evidence are properly observed.

I. Annulment, Declaration of Nullity, and Legal Separation: Clarifying the Terms

In ordinary conversation, people often use the word “annulment” to refer to any court case that dissolves or invalidates a marriage. Under Philippine law, however, there are important distinctions.

1. Declaration of Nullity of Marriage

A declaration of nullity applies to a marriage that is considered void from the beginning. Common grounds include:

Psychological incapacity under Article 36 of the Family Code;
Bigamous or polygamous marriages;
Incestuous marriages;
Void marriages by reason of public policy;
Marriages solemnized without a valid marriage license, subject to exceptions;
Marriages where essential or formal requisites are absent.

In these cases, the court does not “cancel” a valid marriage. Rather, it declares that the marriage was void from the start.

2. Annulment of Voidable Marriage

Annulment applies to a marriage that was valid at the beginning but may be annulled because of a defect existing at the time of marriage. Grounds include:

Lack of parental consent for a party aged 18 to below 21 at the time of marriage;
Insanity;
Fraud;
Force, intimidation, or undue influence;
Physical incapacity to consummate the marriage;
Serious and incurable sexually transmissible disease.

A voidable marriage remains valid until annulled by a court.

3. Legal Separation

Legal separation does not dissolve the marriage bond. The spouses remain married, but they are allowed to live separately, and the court may address property relations, custody, support, and related matters. Grounds include repeated physical violence, drug addiction, lesbianism or homosexuality as a statutory ground under the Family Code, sexual infidelity or perversion, abandonment, and other grounds provided by law.

Although this article uses the common term “annulment,” much of the discussion also applies to petitions for declaration of nullity and, with some differences, legal separation.

II. Does the Other Spouse Need to Agree?

No. A Philippine annulment or declaration of nullity case does not require the consent of the other spouse.

The case is filed by the petitioner against the respondent spouse. If the respondent disagrees, the case becomes contested. If the respondent refuses to participate, the case may still proceed, but the court must be satisfied that the respondent was properly notified and given an opportunity to be heard.

The court will not grant the petition merely because the respondent is absent. The petitioner must still prove the legal ground relied upon.

In short:

The respondent’s consent is not required.
The respondent’s attendance is not always required.
The petitioner must still prove the case.
The court must still protect the State’s interest in preserving marriage.
Collusion between the spouses is prohibited.

III. Why Marriage Cases Are Treated Differently

Marriage is considered an institution impressed with public interest. Because of this, the State is not a passive observer in annulment and nullity cases.

Even when the respondent spouse refuses to appear, the case is not automatically treated like an ordinary civil case where a defendant’s failure to answer may lead to judgment by default. In marriage cases, courts are careful because the parties may be colluding to obtain a decree.

For this reason, the public prosecutor or the Office of the Solicitor General may be involved depending on the stage and nature of the case. The court must ensure that the petition is not based on fabricated facts or mutual convenience.

The judge must determine whether a true legal ground exists.

IV. What Happens If the Respondent Spouse Refuses to Attend?

The effect depends on what stage the case is in and whether the respondent was properly served.

1. If the Respondent Was Not Properly Served Summons

The court cannot validly proceed against a respondent unless jurisdiction over the respondent has been acquired in accordance with procedural rules.

In simple terms, the respondent must be properly notified that a case has been filed.

If summons is defective, the respondent may later challenge the proceedings. This can cause delay, nullify orders, or create grounds for appeal.

Proper service of summons is therefore critical.

2. If the Respondent Was Properly Served but Does Not Answer

If the respondent receives summons and a copy of the petition but does not file an answer, the case may move forward.

However, in marriage cases, the court does not simply declare the respondent “in default” in the ordinary sense. The court generally directs the public prosecutor to investigate whether collusion exists between the parties.

If no collusion is found, the case proceeds to pre-trial and trial, where the petitioner must present evidence.

3. If the Respondent Files an Answer but Later Stops Attending

If the respondent initially participates but later refuses to attend hearings, the court may continue with the proceedings after proper notice.

The respondent’s absence may mean losing the opportunity to cross-examine witnesses, object to evidence, present contrary evidence, or argue defenses.

Still, the petitioner must prove the case.

4. If the Respondent Appears Only to Delay the Case

Sometimes a respondent attends selectively, files repeated motions, or avoids hearings to delay proceedings. Courts may address dilatory tactics through procedural orders, denial of baseless motions, setting of continuous trial dates, or allowing the case to proceed when notices have been properly served.

A respondent cannot use non-appearance as a permanent shield against adjudication.

V. Service of Summons: The First Major Issue

Before the case can proceed, the respondent must be served with summons.

1. Personal Service

The preferred mode is personal service. This means the summons and petition are personally delivered to the respondent.

2. Substituted Service

If personal service is not possible despite diligent efforts, substituted service may be allowed. This may involve leaving copies with a person of suitable age and discretion at the respondent’s residence or with a competent person in charge at the respondent’s office, depending on the circumstances and the rules.

Substituted service must be justified. Courts usually require proof that personal service was attempted and failed for valid reasons.

3. Service When the Respondent Is Abroad

If the respondent is outside the Philippines, service may require special procedures. Depending on the circumstances, the court may allow extraterritorial service, service by publication, service through appropriate channels, or other modes authorized by the Rules of Court.

Cases involving respondents abroad require careful handling because defective service may later affect the validity of the judgment.

4. Unknown Address or Cannot Be Located

If the respondent’s whereabouts are unknown, the petitioner may need to show diligent efforts to locate the respondent. The court may require proof of attempts to find the spouse, such as inquiries with relatives, last known employers, barangay records, social media traces, immigration-related information where lawfully available, or other reasonable means.

The court does not usually accept a bare statement that the respondent “cannot be found.” Diligence must be shown.

VI. Can the Court Declare the Respondent in Default?

In ordinary civil actions, a defendant who fails to answer may be declared in default. But in actions for annulment, declaration of nullity, or legal separation, courts are more cautious.

The reason is that the law seeks to prevent collusion. The spouses might pretend to be adversaries while actually agreeing to obtain a decree. Because of this, the absence or silence of the respondent does not automatically entitle the petitioner to relief.

Instead, when the respondent fails to answer, the court may order the public prosecutor to investigate whether there is collusion. If the prosecutor finds no collusion, the case proceeds, and the petitioner presents evidence.

The practical result is similar to an uncontested presentation of evidence, but the legal framework is stricter than ordinary default.

VII. What Is Collusion?

Collusion means an improper agreement between the spouses to make it appear that a legal ground exists when it does not, or to suppress evidence that would defeat the petition.

Examples may include:

Agreeing that the respondent will not oppose the case in exchange for money or property;
Fabricating facts to fit a legal ground;
Suppressing evidence that the marriage is valid;
Coordinating testimony to mislead the court;
Using the case merely as a convenient substitute for divorce.

The mere fact that the respondent does not appear does not automatically prove collusion. But it may trigger the court’s duty to inquire.

VIII. The Role of the Public Prosecutor

The public prosecutor may be directed to investigate whether collusion exists. This may involve reviewing the petition, checking the respondent’s failure to answer, and determining whether there are indications that the spouses are cooperating to obtain a fraudulent decree.

If there is no collusion, the prosecutor may inform the court accordingly.

If collusion is suspected, the prosecutor may oppose the petition or participate more actively to protect the State’s interest.

In some cases, the public prosecutor may also appear during trial to ensure that evidence is properly tested, especially if the respondent is absent.

IX. The Role of the Office of the Solicitor General

The Office of the Solicitor General represents the Republic in many cases involving the status of marriage, especially at appellate stages. The OSG may participate to defend the validity of marriage or to ensure that decrees of nullity or annulment are issued only when legally justified.

The State’s participation underscores that annulment and nullity proceedings are not purely private arrangements between spouses.

X. If the Respondent Refuses to Attend Pre-Trial

Pre-trial is an important stage where the court simplifies issues, considers admissions, marks evidence, explores settlement of related matters, and sets the course of trial.

In marriage cases, the core issue of marital validity cannot be settled by compromise. However, related matters may be discussed, including:

Custody;
Support;
Visitation;
Property relations;
Liquidation of common property;
Protection orders, where relevant;
Attorney’s fees and costs.

If the respondent was properly notified but fails to attend pre-trial, the court may allow the case to proceed. The respondent may lose procedural opportunities, such as the chance to define issues, object to proposed exhibits, or participate in stipulations.

However, the petitioner must still prove the ground for annulment or nullity.

XI. If the Respondent Refuses to Attend Trial

If the respondent refuses to attend trial despite notice, the petitioner may present evidence ex parte, subject to the court’s control and the participation of the prosecutor where required.

The petitioner may present:

Personal testimony;
Testimony of family members or other witnesses;
Expert testimony, especially in psychological incapacity cases;
Documents;
Medical records, where relevant and admissible;
Psychological evaluation reports;
Birth certificates of children;
Marriage certificate;
Communications, photographs, financial records, or other relevant evidence;
Proof of separation, abandonment, violence, addiction, or other facts depending on the ground.

The absence of the respondent does not mean the court will believe everything the petitioner says. The court evaluates credibility, consistency, relevance, and sufficiency of evidence.

XII. Psychological Incapacity Cases and Non-Attendance of Respondent

Many Philippine nullity cases are based on psychological incapacity under Article 36 of the Family Code.

A frequent concern is whether the respondent spouse must personally submit to psychological evaluation. In practice, a respondent who refuses to participate can complicate the case, but refusal does not necessarily make the case impossible.

The petitioner may rely on:

The petitioner’s testimony;
Testimony of relatives, friends, or persons who observed the marriage;
Records and communications;
Expert opinion based on interviews with the petitioner and collateral sources;
Behavioral history before, during, and after the marriage;
Specific acts showing incapacity to comply with essential marital obligations.

The Supreme Court has clarified over time that psychological incapacity is a legal concept, not merely a medical diagnosis. Expert testimony may be helpful but is not always indispensable in the same rigid way it was once treated. Still, in practice, psychological reports and expert testimony often remain important.

If the respondent refuses examination, the expert may prepare an assessment based on available information, but the probative value depends on the depth, reliability, and factual basis of the report.

XIII. Can the Respondent Be Forced to Attend?

Generally, a spouse cannot be forced to support the annulment case or testify in favor of the petitioner. However, a party may be subject to court processes such as subpoenas in appropriate circumstances.

That said, compelling a respondent’s personal attendance may not always be practical or necessary. Courts can proceed if the respondent was properly notified and the petitioner can prove the case through other competent evidence.

If the respondent is subpoenaed and unjustifiably refuses to obey, the court may impose sanctions available under procedural rules. But the strategic value of compelling attendance depends on the facts.

Sometimes, a hostile or uncooperative respondent may do more harm than good to the petitioner’s presentation. In other cases, the respondent’s testimony may be essential.

XIV. Due Process: The Key Requirement

The constitutional requirement of due process means the respondent must be given notice and an opportunity to be heard. It does not mean the respondent can defeat the case by refusing to use that opportunity.

Due process is satisfied when:

The respondent is properly served summons;
The respondent receives required notices;
The respondent is given a chance to answer;
The respondent is notified of hearings;
The respondent is allowed to participate if they choose;
The court observes procedural rules.

If the respondent ignores the case after valid notice, the court may proceed.

XV. Common Reasons a Respondent Refuses to Attend

A respondent may refuse to attend for many reasons:

Emotional resentment — The respondent wants to make the process harder.
Financial pressure — The respondent believes non-attendance will force a settlement.
Misunderstanding of the law — The respondent thinks the case cannot proceed without their signature.
Fear of exposure — The respondent wants to avoid testimony about misconduct.
Residence abroad — The respondent finds participation inconvenient.
Indifference — The respondent no longer cares about the marriage or case.
Strategic silence — The respondent hopes procedural defects will later invalidate the judgment.
Religious or moral objection — The respondent does not believe in annulment.
New relationship — The respondent wants to avoid involvement but does not oppose the outcome.
Avoidance of support or property issues — The respondent fears related financial claims.

The petitioner’s lawyer must determine whether the refusal is harmless, curable by notice, or part of a larger litigation strategy.

XVI. Can Refusal to Attend Help the Petitioner’s Case?

Sometimes, the respondent’s refusal to attend may support the petitioner’s narrative, especially if the alleged ground involves abandonment, refusal to assume marital obligations, lack of responsibility, or persistent disregard of family duties.

However, non-attendance alone is not usually enough to prove annulment or nullity.

For example:

A spouse’s refusal to attend hearings does not by itself prove psychological incapacity.
A spouse’s silence does not prove fraud.
A spouse’s absence does not prove force or intimidation at the time of marriage.
A spouse’s failure to participate does not automatically prove abandonment under the legal standards required.

The refusal may be relevant, but it must connect to the legal ground.

XVII. Evidence Still Required Despite Non-Attendance

The petitioner must prove the specific ground alleged.

For Psychological Incapacity

Evidence should show that the incapacity:

Relates to essential marital obligations;
Existed at the time of marriage, even if it became obvious later;
Is serious enough to make the spouse truly incapable, not merely unwilling;
Is supported by concrete facts, not conclusions.

Examples of relevant facts may include chronic irresponsibility, extreme emotional immaturity, persistent infidelity linked to incapacity, inability to provide support, abandonment, violence, addiction, manipulation, or other patterns depending on the case.

For Fraud

The petitioner must prove concealment or misrepresentation of a fact recognized by law as fraud sufficient to annul a marriage. Not every lie is legal fraud.

For Force or Intimidation

The petitioner must show that consent to marriage was obtained through force, intimidation, or undue influence and that the action was filed within the required period.

For Physical Incapacity

The petitioner must prove incapacity to consummate the marriage, that it existed at the time of marriage, continues, and appears incurable.

For Sexually Transmissible Disease

The petitioner must prove that the disease was serious, incurable, and existing at the time of marriage.

XVIII. Time Limits Matter in Annulment Cases

Some annulment grounds have prescriptive periods. This is one reason legal advice should be obtained early.

For example, actions based on lack of parental consent, insanity, fraud, force, physical incapacity, or sexually transmissible disease are subject to specific periods and rules on who may file.

By contrast, many void marriage cases, such as declaration of nullity under Article 36, are generally treated differently because the marriage is void from the beginning.

A respondent’s refusal to attend does not extend or suspend deadlines unless the law or rules provide a basis.

XIX. The Mandatory Cooling-Off Period in Legal Separation

Legal separation has special rules not identical to annulment or nullity. One notable feature is the cooling-off period, during which the court generally cannot proceed to trial for a certain period after filing.

This reflects the law’s policy of encouraging reconciliation where possible.

If the respondent refuses to attend in a legal separation case, the case may still eventually proceed, but the court must observe the special rules applicable to legal separation.

XX. Child Custody, Support, and Property Issues When Respondent Is Absent

Even if the respondent refuses to attend, the court may still address related matters.

1. Custody

The court applies the best interests of the child standard. For children below seven years old, maternal preference may apply, subject to exceptions involving compelling reasons.

The respondent’s absence may affect the court’s evaluation, especially if the absent spouse fails to present a parenting plan or evidence of fitness.

2. Support

The court may issue orders regarding child support or spousal support where proper. The petitioner must present evidence of the child’s needs and the respondent’s capacity, if available.

If the respondent hides income or refuses to disclose financial records, the petitioner may use available documents, lifestyle evidence, employment information, business records, or other lawful proof.

3. Property Relations

Depending on the marriage regime, the court may address absolute community property, conjugal partnership, separation of property, or co-ownership.

If the respondent refuses to participate, liquidation may still proceed, but proof of assets, debts, acquisitions, and contributions becomes important.

4. Visitation

If the respondent does not participate, the court may still craft appropriate visitation arrangements based on the evidence. A respondent who later seeks visitation may need to apply for appropriate relief.

XXI. What If the Respondent Is Abroad?

Many Philippine annulment and nullity cases involve a spouse living abroad. The respondent may refuse to come home or participate.

The case may still proceed if service of summons and notices comply with the rules.

Practical issues include:

Locating the respondent’s foreign address;
Translating or authenticating documents when necessary;
Coordinating service through court-approved means;
Handling time zone issues for remote testimony, if allowed;
Presenting evidence from witnesses in the Philippines;
Dealing with foreign divorce or remarriage issues;
Enforcing support or property orders abroad.

If the respondent is a foreigner who obtained a valid divorce abroad, a different remedy may be involved, particularly recognition of foreign divorce, depending on the facts.

XXII. What If the Respondent Cannot Be Found?

When the respondent cannot be located, the petitioner must show diligent efforts to find them. Courts are careful because a judgment affecting marital status must be based on proper notice.

The petitioner may need to submit:

Last known address;
Barangay certifications;
Returned mail or service reports;
Affidavits of attempts to locate;
Information from relatives or acquaintances;
Employment or business address attempts;
Online or public-record traces, where lawful and relevant;
Other proof required by the court.

Service by publication or other alternative modes may be available only when justified and authorized.

XXIII. Can the Respondent Later Challenge the Decision?

Yes, depending on the circumstances.

A respondent who refused to attend may later attempt to challenge the decision by claiming:

Lack of proper summons;
Lack of jurisdiction;
Denial of due process;
Fraud;
Extrinsic fraud;
Defective service;
Lack of notice of hearings;
Collusion;
Insufficient evidence;
Procedural irregularities.

However, if the respondent was properly served and chose not to participate, the challenge may fail.

This is why strict compliance with procedure is essential. A petitioner should not rush service or rely on shortcuts.

XXIV. What If the Respondent Suddenly Appears Late in the Case?

A respondent may ignore the case for months and then suddenly appear. The court may allow participation depending on the stage of the case and the reason for delay.

Possible outcomes include:

The respondent may be allowed to file pleadings;
The respondent may be allowed to cross-examine future witnesses;
The respondent may be denied relief if delay is unjustified;
The court may reopen certain matters in the interest of justice;
The court may impose conditions or costs;
The case may proceed without repeating completed stages.

Courts balance due process with the need to prevent delay.

XXV. Can the Parties Enter Into a Settlement?

The validity of marriage cannot be settled by agreement. Spouses cannot stipulate that a marriage is void or voidable and bind the court.

However, they may settle related issues, such as:

Custody arrangements;
Visitation;
Support;
Property division, subject to law and court approval;
Payment of obligations;
Use of family home;
Parenting schedules.

Any settlement must not be collusive or designed to manufacture grounds for annulment.

XXVI. Practical Steps for a Petitioner When the Spouse Refuses to Attend

1. Secure Correct Address Information

The case may be delayed if summons cannot be served. Gather all possible addresses:

Residence;
Work address;
Provincial address;
Foreign address;
Address of relatives;
Email or messaging details, if relevant to court-approved service;
Last known address.

2. Preserve Evidence

Collect documents and communications early. These may include:

Marriage certificate;
Birth certificates of children;
Photos;
Messages;
Emails;
Medical records;
Police or barangay blotters;
Financial records;
Proof of abandonment;
Proof of addiction, violence, infidelity, or other relevant conduct;
Witness statements.

3. Identify Witnesses

Witnesses may include relatives, friends, neighbors, co-workers, counselors, doctors, or others who observed the spouses’ relationship.

4. Prepare for Collusion Inquiry

If the respondent does not answer, the court may require the prosecutor to investigate possible collusion. The petitioner should be ready to show that the case is genuine and supported by evidence.

5. Avoid Communicating Improper Offers

Do not offer money or concessions in exchange for the respondent’s non-appearance or cooperation in fabricating facts. This can damage the case.

6. Keep Proof of Notices

The record should clearly show that the respondent was notified of proceedings. Proper documentation protects the judgment from later attack.

7. Do Not Assume Silence Means Victory

Even uncontested cases can be denied if evidence is weak. The petition must be carefully prepared.

XXVII. Practical Steps for a Respondent Who Does Not Want to Attend

A respondent who refuses to attend should understand the risks.

Non-attendance may result in:

Loss of opportunity to oppose the petition;
Loss of opportunity to cross-examine witnesses;
Loss of opportunity to present evidence;
Orders on custody, support, and property being issued without the respondent’s side;
Difficulty challenging findings later if notices were valid.

If the respondent disagrees with the petition, the better course is usually to participate through counsel.

If the respondent does not oppose the annulment but wants to protect property, custody, or support rights, participation may still be important.

XXVIII. Remote Appearance and Modern Court Practice

Philippine courts have increasingly used electronic filing, videoconferencing, and remote hearings in appropriate cases. Availability depends on court rules, judicial discretion, local practice, and the circumstances of the case.

A respondent abroad or outside the province may ask the court for permission to appear remotely. Likewise, witnesses may sometimes testify by videoconference if allowed.

Refusal to attend is different from inability to attend. A spouse who genuinely cannot appear physically may still participate through counsel or seek court permission for alternative arrangements.

XXIX. How Long Can a Non-Attending Spouse Delay the Case?

A non-attending spouse can cause delay, especially at the summons stage. If the respondent evades service or lives abroad, the petitioner may need additional motions and court orders.

Once valid service is completed and notices are properly given, continued refusal to attend usually becomes less effective as a delaying tactic.

The largest delays usually arise from:

Difficulty serving summons;
Court docket congestion;
Incomplete documents;
Weak or changing allegations;
Unavailable witnesses;
Psychological evaluation scheduling;
Prosecutor availability;
Motions filed by the respondent;
Issues involving children or property.

A spouse’s absence alone does not have to stop the case indefinitely.

XXX. Can a Case Be Granted Without the Respondent Ever Appearing?

Yes, it is possible, but only if legal and procedural requirements are met.

The petitioner must show:

The court has jurisdiction;
The respondent was properly served or notified under the rules;
There is no collusion;
The petition states a valid legal ground;
The evidence proves that ground;
Related issues are properly addressed;
The decision complies with substantive and procedural law.

The respondent’s total absence does not prevent judgment if due process was observed.

XXXI. Can the Petition Be Denied Even If the Respondent Does Not Attend?

Yes.

The petition may be denied if:

The ground alleged is not recognized by law;
The evidence is insufficient;
The testimony is vague or inconsistent;
Psychological incapacity is not proven;
The petition is based merely on incompatibility;
The case appears collusive;
The action was filed beyond the allowed period;
The court lacks jurisdiction;
Summons or notice was defective;
Required documents are missing;
The petitioner fails to appear or prosecute the case.

Annulment is not granted by default. It must be proven.

XXXII. Common Misconceptions

Misconception 1: “My spouse must sign before I can file.”

False. The petitioner may file without the respondent’s consent.

Misconception 2: “If my spouse does not attend, I automatically win.”

False. The petitioner must still prove the case.

Misconception 3: “My spouse can block the case forever by ignoring it.”

False. Once valid service and notice are completed, the case may proceed.

Misconception 4: “Annulment is just a mutual agreement.”

False. The court decides based on legal grounds and evidence.

Misconception 5: “If we both want it, the court will grant it.”

False. Mutual desire to separate is not a legal ground.

Misconception 6: “A psychological report alone guarantees approval.”

False. The report must be supported by credible facts and testimony.

Misconception 7: “Non-attendance means abandonment is proven.”

False. Refusal to attend hearings may be relevant, but abandonment or incapacity must be proven according to law.

XXXIII. Strategic Considerations for the Petitioner

1. Build the Case as If It Will Be Contested

Even if the respondent is absent, the court will examine the evidence. A strong petition should not depend on the respondent’s silence.

2. Avoid Overstating Allegations

Exaggerated claims can harm credibility. Courts prefer specific, concrete facts over dramatic conclusions.

3. Use Corroborating Evidence

Testimony is stronger when supported by documents, witnesses, records, or expert analysis.

4. Prepare for Questions from the Court

Judges may ask detailed questions, especially in psychological incapacity cases. The petitioner should be ready to explain facts clearly.

5. Handle Children and Property Responsibly

Courts may scrutinize whether the petition protects children’s welfare and properly accounts for property.

6. Ensure Procedural Cleanliness

A favorable decision is vulnerable if the respondent was not properly served or notified.

XXXIV. Strategic Considerations for the Respondent

A respondent who receives summons should not ignore it casually. Even if the respondent believes the case is baseless, failure to participate can result in the court hearing only the petitioner’s evidence.

A respondent should consider participating if they want to:

Oppose the petition;
Protect custody rights;
Seek visitation;
Contest support claims;
Protect property interests;
Prevent false allegations from becoming judicial findings;
Raise jurisdictional or procedural objections;
Avoid being surprised by final orders.

Participation does not necessarily mean admitting the petition. A respondent may participate precisely to oppose it.

XXXV. Ethical Issues

Annulment proceedings must be handled truthfully. Lawyers and parties must not fabricate grounds, coach witnesses to lie, conceal material facts, or stage non-appearance to create an illusion of opposition.

A spouse’s refusal to attend should be dealt with through proper procedure, not manipulation.

False testimony may expose parties and witnesses to legal consequences.

XXXVI. Effect of the Final Decree

If the court grants annulment or declaration of nullity, the decision does not immediately mean the parties can remarry the next day. Certain steps may still be required, such as finality of judgment, issuance of decree, registration with the civil registry, and compliance with property liquidation or recording requirements.

Failure to complete post-judgment requirements can create problems, especially for remarriage.

A respondent who did not attend may still be affected by the judgment once it becomes final, provided due process was observed.

XXXVII. Remedies After Judgment

Depending on timing and grounds, an aggrieved respondent may consider remedies such as:

Motion for reconsideration;
Appeal;
Petition for relief from judgment;
Annulment of judgment;
Petition questioning jurisdiction;
Other remedies available under the Rules of Court.

The availability of remedies depends on the facts, dates, notice, finality, and nature of the alleged defect.

A respondent who deliberately ignored valid notices may have fewer viable remedies than one who was genuinely deprived of notice.

XXXVIII. Practical Example

Suppose a wife files a petition for declaration of nullity based on psychological incapacity. The husband receives summons but refuses to file an answer or attend hearings. The court directs the prosecutor to investigate whether the parties are colluding. The prosecutor finds no collusion. The case proceeds.

The wife testifies. Her psychologist testifies. Her relatives testify about the husband’s long-standing behavior, inability to assume marital obligations, abandonment, and destructive patterns that existed from the beginning of the marriage. Documents and communications are presented.

The husband never appears.

The court may grant the petition if the evidence proves psychological incapacity under the law. But the court may also deny it if the evidence shows only incompatibility, ordinary marital conflict, irresponsibility, or failure of the relationship without legal incapacity.

The husband’s absence allows the case to proceed, but it does not supply the missing legal ground.

XXXIX. Key Takeaways

The respondent’s consent is not required.
The case may proceed if summons and notices are properly served.
The petitioner must still prove the legal ground.
There is no automatic victory by default in marriage cases.

Once due process is satisfied, absence usually does not stop trial.
Procedural defects can later endanger the judgment.
Evidence remains the heart of the case.
Related issues such as custody, support, and property may still be decided.
Respondents who ignore proceedings risk losing the chance to protect their rights.
Petitioners should prepare the case carefully even if uncontested.
A final decree requires proper post-judgment steps before remarriage.

Conclusion

In the Philippines, annulment and declaration of nullity proceedings do not depend on the willingness of the other spouse to attend hearings. A respondent spouse may refuse to participate, ignore summons, avoid hearings, or decline to cooperate, but such refusal does not necessarily defeat the case.

What matters is whether the court acquired jurisdiction, whether due process was observed, whether there is no collusion, and whether the petitioner can prove a valid legal ground with competent evidence.

The absent spouse does not control the outcome. Neither does the petitioner win automatically. The court decides based on law, procedure, and proof.

For petitioners, the best approach is to treat the case seriously from the beginning: ensure proper service, prepare strong evidence, avoid collusion, and comply with every procedural requirement. For respondents, ignoring the case may be risky, especially where custody, support, property, reputation, and future marital status are involved.

A spouse’s refusal to attend hearings may slow the process, but it does not have to stop justice from moving forward.
