Psychological Incapacity as a Ground for Declaration of Nullity of Marriage (A Survey of Landmark Jurisprudence)

Psychological incapacity is one of the most heavily litigated grounds for the declaration of nullity of marriage under the Family Code (E.O. 209). While jurisprudence has significantly evolved, these developments must not be misconstrued as a dilution of the sanctity of marriage or a lowering of the threshold for nullity. Rather, the Supreme Court has sought to clarify the proper meaning, evidentiary requirements, and application of psychological incapacity, thereby ensuring that the statutory provision is applied in accordance with its intent.

Under Article 36 of the Family Code,

“Article 36. 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 (As amended by Executive Order 227).” 

Accordingly, the Supreme Court first wrestled with the definitive boundaries of this provision in the seminal case of Santos vs. Court of Appeals (CA) and Bedia-Santos, G.R. No. 112019 (01-04-1995), where it held that psychological incapacity cannot be established by mere marital failure or abandonment. After examining the Code Committee deliberations, the Court clarified that psychological incapacity refers to “the most serious cases of personality disorders clearly demonstrative of an utter insensitivity or inability to give meaning and significance to the marriage.” 

Drawing heavily from the canon law origins of Article 36 and the writings of Dr. Gerardo Veloso, former Presiding Judge of the Metropolitan Marriage Tribunal of the Catholic Archdiocese of Manila, the Court identified the defining hallmarks, holding that psychological incapacity must be characterized by (a) gravity, (b) juridical antecedence, and (c) incurability.

Building on these three foundational criteria, the Supreme Court, in Republic vs. Court of Appeals (CA) and Molina, G.R. No. 108763 (02-13-1997), further refined the doctrine in a case involving a petition for nullity of marriage based on the husband’s alleged psychological incapacity, characterized by irresponsibility in family support, financial dependence on his parents, and eventual abandonment of his wife and child during a period of economic hardship.

Following extensive consultations with amici curiae, the Court formulated a strict eight-point standard that came to be known as the Molina Guidelines for proving psychological incapacity: the burden of proof, root cause, existence at the time of marriage, incurability, gravity, essential marital obligations, respect for church views, and role of state prosecutors. 

For over a decade, the Molina Guidelines served as an unforgiving gauntlet. Between 1997 and 2008, virtually all petitions failed to clear this high bar, with Antonio vs. Reyes, G.R. No. 155800 (03-10-2006), standing out as a rare exception that satisfied all requirements. 

Amidst this rigid landscape, a window of procedural flexibility opened in Marcos vs. Marcos, G.R. No. 136490 (10-19-2000), where the Court declared that a medical or psychological examination of the respondent is not a mandatory requirement for proving psychological incapacity. Rather, it held that a finding of psychological incapacity may be sustained on the basis of the totality of evidence presented, without the necessity of subjecting the party concerned to clinical evaluation.

In Ngo Te vs. Yu-Te, G.R. No. 161793 (02-13-2009), the Court acknowledged that the Molina Guidelines had become a straitjacket, forcing all cases into a single rigid framework. As a result, courts were directed to interpret psychological incapacity on a case-to-case basis, focusing on the totality of evidence.

Following this acknowledgement, the Supreme Court, in Kalaw vs. Fernandez, G.R. No. 166357 (01-14-2015), reiterated that courts must avoid strict or mechanical application of fixed assumptions and instead assess each case on its own unique facts, recognizing that no case of psychological incapacity is identical to another. Accordingly, trial courts were tasked with a careful evaluation of the factual milieu, while appellate courts should, as far as practicable, refrain from substituting their own judgment for that of the trial court.

In a groundbreaking jurisprudence, the Supreme Court, in Tan-Andal vs. Andal, G.R. NO. 196359 (05-11-2021), clarified that psychological incapacity is a legal and not strictly a medical concept. It is a durable or enduring personality structure that renders one incapable of complying with the essential marital obligations.

Psychological incapacity need not be proven through expert testimony, as it may be established by ordinary witnesses based on observed behavior before marriage. It is not “incurable” in a clinical sense but must be grave, rooted in a serious psychic cause, and exclude mere personality quirks or emotional fluctuations. As required by law, it must have existed prior to or at the time of the marriage. 

Following this landmark ruling, the Supreme Court has consistently applied the doctrine in subsequent cases. In Clavecilla vs. Clavecilla and Republic, G.R. No. 228127 (03-06-2023), the Court emphasized another liberating aspect of the Tan-Andal Doctrine: the right of either spouse to file. It held that the doctrine of unclean hands does not bar a psychologically incapacitated spouse from seeking relief.

In a definitive integration of long-term abandonment into the Tan-Andal Doctrine, the Court ruled, in Dela Cruz-Lanuza vs. Lanuza and Republic, G.R. No. 242362 (04-17-2024), that a husband’s infidelity, lack of support, and unjustified absence may indicate an incapacity to fulfill marital obligations, emphasizing behavioral dysfunctionality.

Further, in Boado vs. Galvez-Boado and Republic, G.R. No. 263627 (11-04-2024), the Supreme Court addressed the emotional core of marriage and ruled that a spouse’s inability to love or emotionally connect with the partner—if rooted in a genuine personality disorder—may also serve as evidence of psychological incapacity. In emphasizing the fundamental nature of marital obligations, the Court held that loving one’s spouse is an essential, if not the most important, marital obligation.

In Republic v. Tangarorang, G.R. No. 272006 (02-05-2025), the Court addressed the civil status of children in nullity proceedings. While Article 54 explicitly protects children conceived or born during a marriage declared void under Article 36, the Court clarified that children born before marriage who were legitimated by subsequent marriage likewise retain their status and rights despite the subsequent declaration of nullity of that marriage. The Court affirmed that a decree of nullity under Article 36 cannot be used to collaterally strip or revert a legitimated child’s status. 

Lest the public assume that the Tan-Andal Doctrine turned Article 36 into a “divorce by mutual consent,” the Supreme Court in Chan Tee Ten vs. Teen Ten and Republic, G.R. No. 259322 (08-06-2025), affirmed the nullification of a marriage based on the spouse’s severe, pervasive, and controlling behavior. The Court emphasized that while ordinary marital dominance, incompatibility, or character conflicts remain wholly insufficient to sustain a decree of nullity, controlling behavior that is compulsive, deeply ingrained, and destructive of mutual respect and emotional reciprocity demonstrates an utter inability- rather than a mere refusal- to fulfill essential marital duties.

In conclusion, the course of Article 36 jurisprudence reveals a shift from rigid medical dogmatism to a holistic, legal assessment of relationships. By treating psychological incapacity as a structural behavioral defect rather than a clinical disease, the Supreme Court has provided a compassionate but legally sound mechanism to dissolve fundamentally hollow marriages while still upholding the constitutional protection of marriage as an inviolable institution.

In Republic vs. Ramoran-Wong, G.R. No. 276986 (02-03-2026), Supreme Court (SC) Associate Justice Maria Filomena D. Singh noted that while marriage is the foundation of the family and an inviolable social institution, the law must also recognize when it has become harmful and beyond repair:

“Marriage, in its truest form, must be a sanctuary: a space of mutual respect, care, and emotional safety. It must never become a chain that binds a person to a relationship that is not only fundamentally flawed, but damaging. While the ideal remains that individuals choose wisely in love and commitment, the reality is that human beings make mistakes. When a marriage has become irreparably broken, the spouses so deeply incompatible as to render its continued existence unjust, the Court should not stand in the way.”
