How to File for Annulment / Declaration of Nullity of Marriage
In the Philippines, there are two distinct legal remedies to end a marriage: annulment (for voidable marriages under Article 45 of the Family Code) and declaration of nullity (for void marriages under Article 36 for psychological incapacity, Articles 37–38 for bigamous or incestuous marriages, and other grounds). While both remedies result in the dissolution of the marital bond, they differ in legal basis, grounds, and effects. An annulment treats the marriage as valid until a court declares it voidable, while a declaration of nullity treats the marriage as if it never legally existed from the beginning.
Important: No Divorce in the Philippines
The Philippines is one of the few countries in the world that does not recognize divorce for the general population. The only exception is for Filipino Muslims, who may obtain a divorce under Presidential Decree No. 1083 (Code of Muslim Personal Laws). For all other Filipinos, annulment or declaration of nullity of marriage is the only legal way to dissolve a marriage and regain the capacity to remarry. Legal separation, on the other hand, does not dissolve the marriage — it only allows the spouses to live separately but they remain legally married and cannot remarry.
Grounds for Declaration of Nullity (Void Ab Initio)
A void marriage is considered as if it never existed from the very beginning. The following are grounds under the Family Code:
- Psychological Incapacity (Article 36): One or both spouses were psychologically incapacitated to comply with the essential marital obligations of marriage at the time of the celebration. The incapacity must be grave, juridically antecedent (existing before the marriage), and incurable.
- Lack of Marriage License (Article 4): The marriage was solemnized without a valid marriage license, except in cases where no license is required (e.g., marriages in articulo mortis).
- Bigamous Marriage (Article 35): One of the spouses was already legally married to another person at the time of the second marriage.
- Incestuous Marriage (Article 37): The marriage was between parties related by blood within the fourth civil degree of consanguinity (e.g., between siblings, between uncle/aunt and niece/nephew).
- Marriages Against Public Policy (Article 38): These include marriages between step-parents and step-children, between adopting parents and adopted children, and between surviving spouse and the person convicted of killing the other spouse.
Grounds for Annulment (Voidable Marriages)
A voidable marriage is considered valid until annulled by a competent court. Under Article 45 of the Family Code, the following are grounds:
- Lack of Parental Consent (Ages 18–21): The marriage was solemnized without the consent of the parent or guardian of a party who was at least 18 but below 21 years of age at the time of the marriage.
- Fraud: The consent of either party was obtained through fraud, such as non-disclosure of a previous conviction for a crime involving moral turpitude, concealment of pregnancy by another man, concealment of a sexually transmissible disease, or concealment of drug addiction or habitual alcoholism.
- Force, Intimidation, or Undue Influence: The consent of either party was obtained through force, intimidation, or undue influence at the time of the marriage ceremony.
- Physical Incapacity (Impotence): Either party was physically incapable of consummating the marriage and such incapacity continues and appears to be incurable.
- Sexually Transmissible Disease (STD): Either party was afflicted with a sexually transmissible disease found to be serious and appears to be incurable at the time of the marriage.

• The petition is filed in the province or city where the petitioner or respondent resides
• Submit the required number of copies
Step 4: Pay Filing Fees
• Pay the required docket and filing fees at the Office of the Clerk of Court

Step 1: Begin by consulting a family law attorney. Annulment and declaration of nullity cases are complex legal proceedings that require professional representation. A good lawyer will assess the merits of your case, advise you on the most appropriate legal ground to invoke, and give you a realistic timeline and cost estimate. Initial consultations typically cost PHP 1,000–5,000, though some lawyers offer free initial consultations.
Step 2: Your lawyer will draft the petition, which is the formal legal document filed with the court. The petition must state the facts of the case, the legal grounds being invoked, and the relief sought. For Article 36 (psychological incapacity) cases, you will need to undergo a psychological evaluation by a licensed clinical psychologist. The psychologist will interview you, assess your spouse's behavior based on your account and corroborating witnesses, and prepare a detailed report.
Step 3: The petition is filed with the Regional Trial Court (RTC) designated as a Family Court. You must file in the RTC of the province or city where you (petitioner) or your spouse (respondent) has been residing for at least six months prior to the filing. Your lawyer will handle the filing and ensure all procedural requirements are met.
Step 4: Upon filing, you must pay the required docket and filing fees at the Office of the Clerk of Court. The amount depends on the court and the nature of the petition, but generally ranges from PHP 3,000 to PHP 5,000. Keep all official receipts as proof of payment.
Step 5: After the petition is filed and fees are paid, the court issues a summons to the respondent, giving them notice of the case and the opportunity to file an answer within 15 days. If the respondent cannot be personally served (e.g., they are abroad or their whereabouts are unknown), the court may order summons by publication in a newspaper of general circulation.
Step 6: The case proceeds to pre-trial, where the court and the parties discuss the issues, explore the possibility of settlement, and set the trial schedule. During trial, the petitioner presents evidence — testimony of the petitioner, the clinical psychologist (for Art. 36 cases), and corroborating witnesses. The respondent, if participating, may also present evidence. Trial hearings are typically scheduled once or twice a month.
Step 7: The Office of the Solicitor General (OSG) plays a mandatory role in annulment and declaration of nullity cases. The OSG deputizes the city or provincial prosecutor to appear in hearings and ensure that no collusion exists between the spouses. The prosecutor may cross-examine witnesses and file comments or oppositions to protect the integrity of the marriage institution.
Step 8: After all evidence has been presented and the case is submitted for decision, the court renders its judgment. If the petition is granted, the decision must become final and executory after the 15-day appeal period. Once final, you must register the court decree with the Local Civil Registrar where the marriage was registered and with the Philippine Statistics Authority (PSA) to annotate the marriage certificate.

Frequently Asked Questions
Q: How long does an annulment or declaration of nullity take?
The entire process typically takes 1 to 3 years from the filing of the petition to the issuance of the final decree. The timeline depends on several factors, including the court's caseload, the complexity of the case, the availability of witnesses, whether the respondent cooperates or contests the petition, and the efficiency of the lawyer handling the case. In Metro Manila and highly urbanized cities, cases may take longer due to heavier court dockets.
Q: Can I remarry after annulment or declaration of nullity?
Yes. Once the court's decision granting the petition becomes final and executory, and the decree is registered with the Local Civil Registrar and the PSA, you regain the legal capacity to remarry. You must obtain a Certificate of Finality from the court and ensure that the marriage certificate has been properly annotated before entering into a new marriage.
Q: What happens to the children after annulment or declaration of nullity?
Children conceived or born before the decree of annulment or declaration of nullity are considered legitimate. Their legitimacy is not affected by the dissolution of the marriage. The court will determine custody, visitation rights, and child support as part of the proceedings. Under Philippine law, children below seven years of age are generally placed in the custody of the mother, unless there are compelling reasons to rule otherwise.
Q: Can I get an annulment without my spouse knowing?
No. The respondent (your spouse) must be served a summons and given the opportunity to participate in the proceedings. This is a fundamental requirement of due process. If the respondent cannot be personally served (e.g., they are abroad or their whereabouts are unknown), the court may order summons by publication in a newspaper of general circulation. The case can proceed even if the respondent does not file an answer or appear in court, but they must be given proper notice.
Q: What is the difference between annulment and legal separation?
Annulment (or declaration of nullity) dissolves the marriage entirely, meaning the marital bond is severed and both parties are free to remarry. Legal separation, on the other hand, does not dissolve the marriage — it merely allows the spouses to live separately and divides their conjugal properties, but they remain legally married and cannot remarry. Legal separation is governed by different grounds (e.g., repeated physical violence, drug addiction, infidelity) under Articles 55–67 of the Family Code.
Q: Can the Public Attorney's Office (PAO) handle annulment cases?
Yes. The Public Attorney's Office (PAO) can handle annulment and declaration of nullity cases for individuals who qualify as indigent litigants. To qualify, you must pass the means and merit test — your net income must not exceed a certain threshold (currently PHP 14,000/month for Metro Manila and PHP 13,000/month for other areas), and your case must have legal merit. If you qualify, PAO will represent you free of charge. Visit the nearest PAO office with your proof of income and supporting documents to apply for free legal assistance.
Important Reminders
- Annulment and declaration of nullity cases require a lawyer — you cannot file or litigate these cases on your own (pro se) in Philippine courts
- There is no such thing as a "quick" or "express" annulment in the Philippines — beware of fixers or agencies that promise annulment in weeks or months for a fixed fee
- The Office of the Solicitor General (OSG) must participate in all annulment and nullity cases — the court cannot render a valid decision without OSG involvement
- For Article 36 (psychological incapacity) cases, the Supreme Court has issued guidelines under the landmark Tan-Andal v. Andal (2021) ruling, which relaxed the requirements for proving psychological incapacity — consult your lawyer about how this ruling may apply to your case
- After the decision becomes final, you must register the decree with both the Local Civil Registrar (where the marriage was registered) and the PSA to annotate the marriage certificate
- Children born or conceived during the marriage remain legitimate even after the marriage is declared void or annulled — their rights to inheritance and support are protected
- If you cannot afford a private lawyer, visit the Public Attorney's Office (PAO) or the Integrated Bar of the Philippines (IBP) legal aid chapter in your area for free legal assistance
- Always keep certified true copies of all court orders, decisions, and the final decree — you will need these documents for remarriage, property transactions, and other legal purposes
