The High Bar for Psychological Incapacity: Marital Infidelity Alone Is Insufficient for Annulment in the Phili

The Supreme Court clarifies that infidelity alone does not prove psychological incapacity for annulment under Article 36 of the Family Code.


The Supreme Court has consistently held that a marriage cannot be annulled simply because one spouse is unfaithful. In Castillo v. Republic (G.R. No. 214064, February 6, 2017), the Court denied a wife's petition to nullify her marriage, ruling that her husband's sexual infidelity and irresponsibility, without more, did not amount to psychological incapacity under Article 36 of the Family Code. The decision serves as a crucial reminder that the ground of psychological incapacity is reserved for the most serious cases of personality disorders.

The Facts of the Case

Mirasol Castillo and Felipe Impas were friends who became sweethearts. During their courtship, Mirasol discovered that Felipe was still seeing his former girlfriend. Despite this, they reconciled and married in 1984, having two children together.

After thirteen years of marriage, Felipe resumed his philandering ways. Mirasol caught him in a compromising act with another woman, and he neither explained nor apologized. She eventually left the conjugal dwelling and filed a complaint for declaration of nullity of marriage in 2011.

The Evidence Presented

Mirasol presented a clinical psychologist who concluded that Felipe suffered from Narcissistic Personality Disorder. The psychologist's report claimed that Felipe's condition was grave, rooted in his childhood, and incurable. However, the psychologist admitted that she never personally interviewed or examined Felipe. Her conclusions were based solely on interviews with Mirasol and a common friend who did not testify in court.

The Regional Trial Court granted the petition and declared the marriage void. On appeal, the Court of Appeals reversed, and the Supreme Court affirmed the reversal.

The Requirements for Psychological Incapacity

The Supreme Court reiterated that psychological incapacity must be characterized by three elements: gravity, juridical antecedence, and incurability. The incapacity must be grave and serious, rooted in the party's history antedating the marriage, and incurable or beyond the means of the party to cure.

The Court also applied the guidelines from Republic v. Court of Appeals and Molina (G.R. No. 108763, February 13, 1997), which require that the root cause of the incapacity be medically or clinically identified, alleged in the complaint, sufficiently proven by experts, and clearly explained in the decision. Any doubt should be resolved in favor of the validity of the marriage.

Why the Petition Failed

The Court found that the totality of evidence failed to establish Felipe's psychological incapacity. The psychologist's evaluation was based on one-sided information from Mirasol, with no independent witness to corroborate claims about Felipe's upbringing or family history. The Court noted that there was no evidence linking Felipe's infidelity to a disordered personality that prevented him from discharging his marital obligations.

The Court emphasized that irreconcilable differences, sexual infidelity, emotional immaturity, and irresponsibility do not by themselves warrant a finding of psychological incapacity. These may simply reflect a refusal or unwillingness to assume marital obligations, not an incapacity to do so. For infidelity to constitute psychological incapacity, it must be shown to be a manifestation of a disordered personality that completely prevents the spouse from complying with the essential obligations of marriage.

Practical Takeaways

  • Infidelity alone is not enough. A spouse seeking annulment on the ground of psychological incapacity must prove more than just unfaithfulness or irresponsibility.
  • Expert opinion must be well-founded. Psychological evaluations based solely on one spouse's account, without personal examination of the other spouse or corroborating witnesses, carry little weight.
  • Root cause must be established. The psychological incapacity must be shown to exist at the time of the marriage, not merely developed during it.
  • Burden of proof is high. Courts resolve doubts in favor of the validity of marriage, given the State's policy to protect the family as the basic social institution.
  • Evidence must be corroborated. Presenting independent witnesses who can testify to the spouse's pre-marital history and behavior strengthens the case considerably.
