Psychological Incapacity After Tan-Andal: The Laroco Ruling Explained

The Supreme Court's 2022 decision in Laroco v. Laroco offers the clearest practical application yet of the landmark Tan-Andal v. Andal ruling on psychological incapacity. For spouses trapped in marriages marked by persistent discord, the case signals a meaningful shift: proof of a clinical personality disorder is no longer the sole path to nullity. This article explains what changed and what evidence now matters.

Article 36 and the Shift Away from Clinical Diagnosis

Article 36 of the Family Code declares a marriage void if either party, at the time of celebration, was psychologically incapacitated to comply with the essential marital obligations — even if the incapacity only becomes manifest after the wedding.

For years, courts required a medically diagnosed personality disorder to grant nullity. The Supreme Court's ruling in Tan-Andal v. Andal changed that. It refocused the inquiry on mutual incompatibility and antagonism arising from the spouses' respective personality structures. The question is no longer simply "What disorder does this spouse have?" but "Are these two personalities so fundamentally incompatible that they cannot fulfill their marital obligations?"

A controlling spouse paired with a fiercely independent one, for example, may exhibit this dynamic if their traits produce constant conflict and an inability to make joint decisions.

The Laroco Case: Facts and Procedural History

Dionisio and Aurora Laroco married in 1971 and had three children. Dionisio sought to nullify the marriage under Article 36, alleging that Aurora was unfaithful, irresponsible, and had been arrested for estafa. He submitted a psychiatric evaluation diagnosing him with obsessive-compulsive personality disorder and Aurora with histrionic personality disorder.

The Regional Trial Court denied the petition, finding insufficient evidence of psychological incapacity. The Court of Appeals affirmed. The Supreme Court reversed both lower courts.

The Supreme Court's Reasoning

Applying the Tan-Andal framework, the Court found the mutual incompatibility and antagonism between the spouses to be grave and clearly convincing. It pointed to specific evidence:

• The spouses' long separation
• The children "bouncing" from one parent to another
• Persistent accusations of infidelity that continued even as both aged

The Court observed that this state of discord and disharmony undermined the unity and harmony of the family. Significantly, the ruling did not rest on the psychiatric diagnoses. Instead, it treated the spouses' conduct and circumstances as sufficient proof of a deep-seated incapacity to comply with essential marital obligations.

What Laroco Means for Nullity Petitions

The practical effect of Laroco is to lower the evidentiary barrier that once required a formal psychiatric label. A petitioner can now succeed by demonstrating:

1. Mutual incompatibility — irreconcilable differences rooted in the spouses' personalities
2. Clear and convincing evidence — concrete acts, behaviors, and circumstances showing dysfunction
3. Impact on the family — how the discord undermined family unity and harmony

The ruling does not eliminate the need for proof. It redefines what proof looks like. Testimonies, documentary evidence, and the history of the relationship can now carry a case that previously might have failed for lack of a medical certificate.

Practical Takeaways

• A diagnosis is helpful but not required. Courts now look at the totality of circumstances, not just psychiatric labels.
• Document the pattern. Keep records of conflicts, separations, infidelity, and other conduct showing incompatibility.
• Show the impact on the family. Evidence that children were shuttled between parents or that harmony was destroyed strengthens the petition.
• Expect a clear-and-convincing-evidence standard. This is higher than the ordinary civil standard but lower than proof beyond reasonable doubt.
• Juridical antecedence still matters. The root cause must be shown to have existed before the marriage, even if it only became apparent later.
