In the Philippines, the journey to dissolve a marriage is often perceived as a labyrinthine ordeal requiring the cooperation of both parties. A common misconception persists that for an annulment to proceed, both spouses must sign a "joint petition" or agree to the separation. However, under the current legal framework of the Family Code and recent Supreme Court jurisprudence, the reality is quite the opposite: unilateral action is not only possible but is the standard procedural route.
1. The Myth of the "Joint Petition"
Under Philippine law, there is no such thing as a "Joint Petition for Annulment" or "No-Fault Divorce" (as of mid-2026, while the Absolute Divorce Bill has seen historic progress in Congress, it has not yet supplanted the existing system of Nullity and Annulment).
In fact, if two spouses were to file a petition together or openly agree to the annulment, the court would likely dismiss the case on the grounds of collusion. The State has a constitutional mandate to protect marriage as an "inviolable social institution." Therefore, the law requires an adversarial proceeding where one party (the Petitioner) claims the marriage is void or voidable, and the other party (the Respondent) is given the opportunity to defend it.
2. Filing Without a Spouse's Signature
You do not need your spouse’s permission, signature, or "blessing" to file for a Declaration of Nullity (Article 36) or an Annulment (Article 45). The process is initiated by the Petitioner alone. Once the petition is filed in the Regional Trial Court (RTC), the court issues a Summons. This is a formal notice to the other spouse that a case has been filed against them.
What if the Spouse Refuses to Sign the Summons?
A spouse cannot stop the process by simply refusing to sign the papers. If they refuse to receive the summons, the court server can perform "substituted service" (leaving the papers with a responsible person at their residence) or, if their whereabouts are unknown, "service by publication" in a newspaper.
3. Dealing with an Uncooperative or "Missing" Spouse
If the Respondent spouse ignores the summons and fails to file an "Answer" within the reglementary period (usually 30 days), the case does not stop.
- The Collusion Investigation: The court will order the Public Prosecutor to conduct an investigation to ensure that the parties did not "cook up" the case or agree to the annulment behind the scenes.
- Proceeding in Default: If no collusion is found, the court will allow the Petitioner to present evidence ex parte (without the other spouse). Essentially, the case moves forward, and the court will decide based on the evidence provided by the Petitioner.
4. Primary Grounds: The Tan-Andal Standard
Most "annulments" in the Philippines are technically Petitions for Declaration of Absolute Nullity of Marriage under Article 36 of the Family Code, citing Psychological Incapacity.
Since the landmark ruling in Tan-Andal v. Andal (2021), the requirements have shifted significantly:
- Legal, Not Medical: Psychological incapacity is no longer viewed as a clinical "personality disorder" that needs a doctor’s diagnosis. It is a legal concept.
- Totality of Evidence: You do not necessarily need a psychologist to testify, although it remains highly recommended. The court now looks at the "totality of evidence"—the history of the relationship, witness testimonies, and documented behavior—to see if the spouse was truly incapable of fulfilling essential marital obligations (such as mutual love, respect, and support).
5. The Procedural Roadmap
If you are proceeding without your spouse's cooperation, the general timeline follows these stages:
| Stage | Action |
|---|---|
| 1. Preparation | Psychological evaluation (optional but helpful) and gathering of certificates (PSA Marriage/Birth certificates). |
| 2. Filing | The Petition is filed in the RTC of the province/city where the Petitioner has resided for at least 6 months. |
| 3. Summons | The court notifies the Respondent. If they are abroad, extraterritorial service is conducted. |
| 4. Prosecutor's Report | The State checks for collusion. If the spouse is "ghosting" the case, the Prosecutor confirms it isn't a "scam." |
| 5. Pre-Trial | Issues are simplified. Even if the spouse is absent, this stage must occur. |
| 6. Trial Proper | The Petitioner and witnesses testify. Evidence of the "incapacity" or "fraud" is presented. |
| 7. Decision | The Judge issues a ruling. If granted, there is a waiting period for the Decree of Nullity. |
6. Key Takeaways for the Petitioner
- Absence is not an Obstacle: A spouse who is working abroad (OFW) or who has moved away cannot block the case by staying away. The law provides mechanisms to reach them or proceed without them.
- The "Agreement" Trap: Be careful about telling the court your spouse "agrees" to the annulment. This can trigger a collusion investigation that might lead to the dismissal of your case.
- Property and Custody: Even if the spouse doesn't sign the petition, the court can still make rulings on the partition of properties and the custody of children based on the best interests of the minors.
In summary, the lack of a spouse's signature is often a procedural advantage rather than a hurdle. It reinforces the fact that there is no collusion and allows the Petitioner to present their side of the story to the court. While the process remains rigorous, the legal "consent" of a spouse is a requirement that simply does not exist in Philippine matrimonial law.
