Psychological incapacity under Article 36 is a ground to declare a marriage void when a spouse cannot fulfill essential marital obligations for reasons existing at the time of the marriage. After Tan-Andal v. Andal (2021), it is treated as a legal, not strictly medical, concept and need not be proven by a psychiatrist.
Article 36 of the Family Code provides that a marriage contracted by any party who was psychologically incapacitated to comply with the essential marital obligations shall be void from the beginning, even if such incapacity becomes manifest only after its solemnization. It is the most frequently invoked ground for declaration of nullity of marriage in the Philippines, and it has been the subject of more Supreme Court decisions — and more public confusion — than perhaps any other provision in the Family Code.
The landmark 2021 decision in Tan-Andal v. Andal significantly changed the legal landscape for Article 36 petitions, relaxing several of the most burdensome requirements that had previously made these cases difficult and expensive to prove. Understanding what the law currently requires is essential for anyone considering this remedy.
What the Law Requires: The Three Characteristics
Even after Tan-Andal, psychological incapacity under Article 36 must be shown to have three essential characteristics. First, it must be grave — meaning the incapacity must be of such a serious nature that the party is genuinely unable to carry out the ordinary duties required in a marriage. Second, it must be juridically antecedent — meaning the root cause of the incapacity must have existed at the time of the marriage, even if its manifestations became apparent only afterward. Third, it must be incurable — not necessarily in a medical sense, but in the sense that the personality structure of the incapacitated party is so deep-seated that it is highly unlikely to change.
What Changed After Tan-Andal
Prior to Tan-Andal, the controlling guidelines set in Republic v. Molina (1997) required, among other things, that the root cause of psychological incapacity be medically or clinically identified, alleged in the complaint, sufficiently proven by experts, and clearly explained in the court's decision. This effectively made the testimony of a clinical psychologist or psychiatrist — who would personally evaluate one or both spouses — a near-mandatory requirement. Cases became expensive and slow largely because of the cost and logistics of obtaining and presenting this expert testimony.
In Tan-Andal, the Supreme Court En Banc clarified that psychological incapacity is not a medical but a legal concept. Expert testimony from a psychologist or psychiatrist is no longer required — though it may still be presented and will be considered by the court. What is required is clear and convincing evidence, which may consist of the testimonies of the parties, witnesses who personally observed the incapacitated spouse's behavior, and other evidence showing a pattern of conduct that demonstrates the spouse's genuine inability to comply with essential marital obligations.
What Courts Look For in Practice
Post-Tan-Andal, courts evaluate Article 36 cases based on the totality of evidence rather than any single expert report or diagnosis. Patterns of conduct frequently cited in successful petitions include: persistent refusal to provide financial support or fulfill parental responsibilities; chronic infidelity accompanied by a complete lack of remorse or commitment to change; severe narcissistic or antisocial patterns that make genuine marital communion impossible; habitual and serious abuse — whether physical, psychological, or sexual — as evidence of a spouse's incapacity to treat the other with the basic dignity that marriage requires; and emotional immaturity so pronounced that the spouse cannot be expected to fulfill the obligations of married life.
Subsequent decisions have reinforced the Tan-Andal framework. In Dedicatoria v. Dedicatoria (G.R. No. 250618, July 20, 2022), Fopalan v. Fopalan (G.R. No. 250287, July 20, 2022), and Georfo v. Republic (G.R. No. 246933, March 6, 2023), the Supreme Court consistently held that courts must focus on the consistency and totality of evidence, and that the absence of a formal psychiatric diagnosis is not fatal to the petition.
The Role of the OSG and the Prosecuting Fiscal
In every Article 36 petition, the Office of the Solicitor General represents the State and actively participates to ensure that the declaration of nullity is not granted collusion or fraud. A prosecuting fiscal or public prosecutor is assigned to the case at the trial court level to ensure no collusion between the parties. Even if both spouses agree that the marriage should be voided, the court is not bound by their agreement — the petitioner must still present sufficient evidence to satisfy the court and the OSG.
Practical Considerations
While Tan-Andal relaxed the expert testimony requirement, petitions for declaration of nullity under Article 36 remain substantive proceedings requiring well-prepared evidence. The petitioner must still present a coherent narrative supported by testimony and documents — a bare assertion that one's spouse was psychologically incapacitated will not suffice. Counsel plays a critical role in framing the evidence in terms of the three characteristics, identifying the specific patterns of behavior that demonstrate juridical antecedence and gravity, and distinguishing genuine psychological incapacity from ordinary marital difficulties that do not rise to the level of a void marriage.
