In the Philippines, where absolute divorce remains legally unavailable, the Family Code provides specific mechanisms for the dissolution of marriage. The most frequently invoked ground is Psychological Incapacity under Article 36, often erroneously grouped with "Annulment." It is crucial to distinguish between a Petition for Declaration of Nullity (void marriages) and a Petition for Annulment (voidable marriages).
I. Psychological Incapacity (Article 36)
Article 36 of the Family Code states: "A marriage contracted by any party who, at the time of the celebration, was psychologically incapacitated to comply with the essential marital obligations of marriage, shall likewise be void even if such incapacity becomes manifest only after its solemnization."
1. The Traditional Framework (Santos Doctrine)
For decades, the Supreme Court followed the strict criteria set in Santos v. Court of Appeals, requiring that the incapacity exhibit:
- Gravity: The incapacity must be serious such that the party cannot carry out the ordinary duties of marriage.
- Juridical Antecedence: The condition must have existed at the time of the celebration of the marriage.
- Incurability: The incapacity must be incurable or, if curable, the cure is beyond the means of the party involved.
2. The Tan-Andal Paradigm Shift (2021)
The 2021 landmark case of Tan-Andal v. Andal significantly reinterpreted Article 36, making it more accessible while maintaining the sanctity of marriage. Key changes include:
- Legal, Not Medical: Psychological incapacity is now explicitly recognized as a legal concept, not a clinical or medical one. It is no longer necessary to prove a specific personality disorder or mental illness.
- Incurability Redefined: "Incurability" is no longer viewed in the medical sense. Instead, it refers to "legal incurability"—meaning the incapacity is so deep-seated within the individual's personality concerning their spouse that it is unlikely to change.
- Expert Testimony: While still helpful, the testimony of a psychologist or psychiatrist is no longer mandatory. The court can determine incapacity based on the "totality of evidence" provided by witnesses who can testify to the behavior of the parties.
- Quantum of Proof: The petitioner must prove the case by clear and convincing evidence.
3. Essential Marital Obligations
To succeed, the petitioner must prove that the respondent (or both parties) cannot fulfill the obligations listed in Articles 68 to 71 of the Family Code, which include:
- Living together, observing mutual love, respect, and fidelity.
- Rendering mutual help and support.
- The procreation and rearing of children.
II. The Role of Abandonment
It is a common misconception that abandonment is a direct ground for the nullity of marriage. In the Philippine legal system, abandonment serves different roles depending on the remedy sought.
1. Abandonment as Evidence of Psychological Incapacity
While abandonment itself is not a ground for nullity under Article 36, it is often used as a symptom or manifestation of a party's psychological incapacity. If a spouse leaves the family home without intent to return and refuses to provide support, this behavior—when linked to a deep-seated personality trait existing at the time of marriage—supports the claim that they are incapable of fulfilling marital obligations.
2. Legal Separation (Article 55)
Under Article 55, "abandonment of petitioner by respondent without justifiable cause for more than one year" is a ground for Legal Separation.
Important Distinction: Legal separation allows the spouses to live apart and partition properties, but the marriage bond is not severed. Neither party can remarry.
3. Presumptive Death (Article 41)
If a spouse has been absent for four consecutive years (or two years in cases of "danger of death" like a plane crash or shipwreck) and the spouse present has a well-founded belief that the absent spouse is dead, they may file a summary proceeding for the Declaration of Presumptive Death for the purpose of remarriage.
III. Comparison Table: Nullity vs. Legal Separation
| Feature | Declaration of Nullity (Art. 36) | Legal Separation (Art. 55) |
|---|---|---|
| Ground | Psychological Incapacity | Abandonment, Adultery, Violence, etc. |
| Status of Marriage | Void from the beginning (Ab Initio) | Valid but distressed |
| Right to Remarry | Yes, after Finality | No |
| Property Relation | Partition/Liquidation | Dissolution of absolute community/conjugal partnership |
| Children's Status | Generally remain Legitimate | Remain Legitimate |
IV. Procedural Requirements
- Petition: Filed in the Family Court of the province or city where the petitioner or respondent has been residing for at least six months.
- Collusion Investigation: The Public Prosecutor must conduct an investigation to ensure the parties did not agree to "fake" the grounds to get the marriage dissolved.
- Pre-Trial and Trial: Presentation of witnesses, including the petitioner and potentially an expert (psychologist) to explain the root cause of the incapacity.
- Final Decree: If granted, the court issues a Decree of Nullity, which must be registered with the Local Civil Registrar.
V. Legal Consequences
- Legitimacy of Children: Under Article 54, children conceived or born before the judgment of nullity under Article 36 are considered legitimate.
- Custody and Support: The court will determine custody based on the "Best Interests of the Child" rule. Generally, children under seven years old stay with the mother unless there are compelling reasons otherwise.
- Property: Since the marriage is void, the property regime is usually governed by Article 147 or 148 (Co-ownership), meaning properties acquired during the union are generally divided equally if both contributed.
