Here’s a comprehensive legal article on the Steps to File for Annulment of Marriage in the Philippines, covering everything you need to know under Philippine law.

Steps to File for Annulment of Marriage in the Philippines

Filing for annulment in the Philippines is a lengthy, procedural, and often emotionally taxing process governed primarily by the Family Code of the Philippines. Unlike divorce in other jurisdictions, annulment does not simply dissolve the marriage—it declares that the marriage was void from the start due to legal grounds. Below is an in-depth guide.

1. Understanding What Annulment Is

In Philippine law, annulment can mean:

Declaration of Nullity – For marriages that were void from the beginning (e.g., bigamous marriage, lack of marriage license, psychological incapacity).
Annulment Proper – For marriages that are valid until annulled by a court (e.g., lack of parental consent, fraud, force or intimidation).

2. Grounds for Annulment

Under the Family Code, the following are the common grounds:

For Declaration of Nullity (Void from the start)

Psychological incapacity (Article 36)
Marriage without a license (except in special cases under the law)
Bigamous or polygamous marriages
Incestuous marriages
Marriages void under Articles 37 and 38 (e.g., certain degrees of blood relationship)

For Annulment Proper (Valid until annulled)

Lack of parental consent (if one party is 18–21 years old at marriage)
Insanity at the time of marriage
Fraud
Force, intimidation, or undue influence
Physical incapacity to consummate marriage
Sexually transmissible disease existing at the time of marriage

3. Pre-Filing Considerations

Before filing:

Consult a family lawyer — They will assess your case and determine if the facts fit within legal grounds.
Prepare emotionally and financially — Annulments in the Philippines are often costly and can take years.
Gather evidence early — Particularly for psychological incapacity cases, psychiatric evaluations and witness testimonies are essential.

4. Step-by-Step Process

Step 1: Engage Legal Counsel

Retain a lawyer with experience in family law.
Your lawyer will draft and file the Petition for Annulment or Declaration of Nullity before the Regional Trial Court, Family Court where you or your spouse resides.

Step 2: Filing the Petition

The petition includes: personal details, marriage details, grounds, and a prayer for relief.
The court will require payment of filing fees unless you qualify for pauper litigant status.

Step 3: Raffle and Assignment to a Judge

After filing, the case is raffled to a family court judge.

Step 4: Notice to the Public Prosecutor and the Solicitor General

The Public Prosecutor investigates for collusion between parties.
The Office of the Solicitor General (OSG) represents the State’s interest in preserving marriage.

Step 5: Pre-Trial Conference

The judge sets a pre-trial to identify issues and mark evidence.
Failure to appear can result in dismissal.

Step 6: Trial Proper

Presentation of petitioner’s evidence (including expert testimony if applicable).
Cross-examination by the prosecutor and OSG.
Respondent presents their evidence if they oppose.

Step 7: Decision

If granted, the court issues a Decision declaring the marriage void or annulled.
If denied, you may appeal.

Step 8: Registration of the Decision

The decision becomes final and executory after the lapse of appeal period.
A Final Decree of Nullity/Annulment is issued and registered with the Local Civil Registrar and Philippine Statistics Authority (PSA).

5. Documents Commonly Required

PSA-issued marriage certificate
Birth certificates of children (if any)
Marriage license (if applicable)
Proof/evidence supporting the grounds (photos, letters, medical or psychological reports)
Witness affidavits

6. Costs and Duration

Cost: ₱250,000 – ₱450,000+ (varies depending on lawyer, complexity, and location)
Duration: Typically 2–4 years, but can be longer depending on court congestion and opposition.

7. Effects of Annulment

On the parties: They can remarry after registration of the decree.
On property relations: Governed by liquidation rules; conjugal property is divided.
On children: Children conceived or born before annulment remain legitimate (except in certain void marriages, like bigamy without the putative spouse protection).

8. Common Challenges

Psychological incapacity cases require expert testimony and must meet the strict “juridical antecedence” test set in Santos v. CA and Republic v. Molina.
The State is an active party and often opposes annulments.
Emotional toll and family strain.

9. Alternatives to Annulment

Legal separation – Ends marital cohabitation but not the marriage bond.
Declaration of nullity – If the marriage is void ab initio.
Recognition of foreign divorce – If one spouse is a foreigner or becomes one.
