G.R. No. 241144, June 26, 2019
JUANITA E. CAHAPISAN-SANTIAGO, Petitioner, vs. JAMES PAUL A. SANTIAGO, Respondent.

FACTS

Petitioner Juanita E. Cahapisan-Santiago and respondent James Paul A. Santiago met in 1999 when she was 40 and he was 22. Their relationship quickly progressed, and petitioner became pregnant three months later. They married on March 31, 2000. The marriage was marked by frequent quarrels. Respondent alleged petitioner was domineering, as she was the sole breadwinner while he was a high school dropout. They separated in 2005 after years of conflict and lived apart for eleven years.
In 2012, respondent filed a Petition for Declaration of Nullity of Marriage under Article 36 of the Family Code, alleging psychological incapacity. To support his petition, he presented the report of clinical psychologist Ms. Shiela Marie O. Montefalcon. The report diagnosed respondent with Dependent Personality Disorder (DPD), characterized by chronic overdependence on petitioner and his mother to meet emotional and physical needs, difficulty making decisions without excessive advice, fear of expressing disagreement, lack of self-confidence in initiating projects, and a history of substance abuse. The psychologist also diagnosed petitioner with Narcissistic Personality Disorder (NPD), finding a pervasive pattern of grandiosity, need for admiration, and lack of empathy. The expert concluded both parties were psychologically incapacitated and recommended nullity.
Petitioner opposed, arguing respondent was merely immature and irresponsible, not psychologically incapacitated. She contended his past drug dependency was not permanent, as he had reformed, and pointed out that the psychologist’s own report noted respondent’s strengths, such as being assertive, resourceful, and capable in group discussions. She claimed their fights were caused by respondent’s womanizing, not dependency.
The Regional Trial Court (RTC) granted the petition, declaring the marriage null and void based on respondent’s psychological incapacity (DPD). The RTC found respondent’s abandonment of the family and DPD demonstrated an inability to fulfill marital obligations. However, it held there was insufficient evidence to prove the root cause of petitioner’s alleged NPD. The Court of Appeals (CA) affirmed the RTC decision, finding respondent’s DPD medically identified, grave, incurable, and present at the marriage’s inception due to his pre-marriage irresponsibility, drug dependency, and overdependence on his mother.

ISSUE

Whether the marriage between petitioner and respondent should be declared null and void on the ground of respondent’s psychological incapacity (Dependent Personality Disorder).

RULING

No. The Supreme Court reversed the decisions of the lower courts and dismissed the petition for declaration of nullity. The Court held that respondent failed to prove his psychological incapacity with the required gravity, juridical antecedence, and incurability under Article 36 of the Family Code and the guidelines established in Republic v. Molina and its progeny.
The Ratio Decidendi is anchored on the strict interpretation of Article 36, which requires clear evidence that the incapacity is (a) grave, (b) rooted in the party’s history prior to the marriage (juridical antecedence), and (c) incurable. The Court emphasized the constitutional policy to protect and preserve marriage, placing the burden of proof squarely on the petitioner seeking nullity. In this case, the evidence for respondent’s DPD was insufficient and contradictory. While the psychologist’s report listed clinical features of DPD, it also described respondent as assertive, tactful, energetic, and resourceful—traits inconsistent with a severe, incapacitating dependency disorder. The Court found these positive traits undermined the conclusion that his condition was truly grave and wholly debilitating to his marital obligations. Furthermore, the alleged root causes (e.g., family background, upbringing) were not sufficiently explored or linked to a definitive psychological illness that existed at the time of the wedding. The Court also noted that respondent’s behaviors—irresponsibility, drug use, and dependence—could be attributed to mere immaturity, youthful indiscretion, or a failure to exert effort, which do not constitute psychological incapacity. Since the evidence did not convincingly establish that his purported DPD was a permanent and grave psychological defect that completely disabled him from understanding and performing the essential marital obligations from the beginning, the marriage cannot be declared void. The petition for nullity was therefore dismissed.
