In Santos v. Court of Appeals (G.R. No. 112019, January 4, 1995), the Philippine Supreme Court gave the first authoritative reading of “psychological incapacity” under Article 36 of the Family Code and set a three-part test that a petitioner has to meet: the incapacity must be grave, must have existed at the time of the marriage, and must be incurable.1The Lawphil Project. G.R. No. 112019 – Leouel Santos v. Court of Appeals and Julia Rosario Bedia-Santos Justice Jose Vitug wrote the opinion. The framework it built governed Philippine nullity cases for more than two decades, and its core still shapes the analysis today even after the Court has softened the standard around it.
The Marriage That Led to the Case
Leouel Santos, a First Lieutenant in the Philippine Army, married Julia Rosario Bedia on September 20, 1986, in Iloilo City. On May 18, 1988, Julia left for the United States to work as a nurse over Leouel’s objections. She promised to return and never did. After years of failed attempts to locate her, Leouel petitioned to have the marriage declared void, arguing that Julia’s abandonment showed she was psychologically incapable of fulfilling her marital obligations.1The Lawphil Project.

What Article 36 Says
Article 36 of the Family Code declares a marriage void if either spouse was, at the time of the wedding, “psychologically incapacitated to comply with the essential marital obligations of marriage,” even if the incapacity became apparent only later.2ChanRobles Virtual Law Library. Executive Order No. 209 – The Family Code of the Philippines The drafters left the phrase undefined on purpose. They worried that a fixed list of examples would prevent courts from applying the concept to situations they had not foreseen.1The Lawphil Project. G.R. No. 112019 – Leouel Santos v. Court of Appeals and Julia Rosario Bedia-Santos
The “essential marital obligations” being referenced sit in Articles 68 through 71: the duty to live together, to observe mutual love, respect, and fidelity, to render mutual help and support, and to jointly manage the household and support the family.2ChanRobles Virtual Law Library. Executive Order No. 209 – The Family Code of the Philippines A petition under Article 36 argues that a spouse is fundamentally unable, not merely unwilling, to meet one or more of these duties.
The Three-Part Test the Court Laid Down
Santos gave psychological incapacity a workable definition by attaching three conditions to it. Each has to be shown; missing any one is fatal to the petition.3Supreme Court E-Library. G.R. No. 112019 – Santos v. Court of Appeals
Gravity. The condition has to be a genuine inability to understand and carry out the essential marital obligations. Refusal, difficulty, or plain neglect does not count. Personality quirks, mood swings, and ordinary emotional friction fall outside the rule.
Juridical antecedence. The condition has to have existed at the time of the wedding, even if nothing about it was visible then. A problem that developed only years into the marriage will not support a nullity petition.
Incurability. The condition has to be enduring enough that it cannot be resolved through treatment or the passage of time.
Why Leouel Santos Lost
Applying that test to its own facts, the Court denied Leouel’s petition. Julia’s departure and prolonged silence were painful, but they did not by themselves prove a grave psychological condition that predated the marriage. Abandonment showed the marriage had failed; it did not show incapacity in the specific legal sense the Court was defining.1The Lawphil Project. G.R. No. 112019 – Leouel Santos v. Court of Appeals and Julia Rosario Bedia-Santos The ruling drew a firm line between a broken marriage and a void one.
Declaration of Nullity Is Not Annulment
A successful Article 36 petition produces a declaration of nullity, which treats the marriage as void from the beginning. Annulment is a separate remedy under Article 45 of the Family Code that voids a marriage which was valid until the court acted on grounds like fraud or lack of parental consent. Filipinos often use “annulment” loosely to cover both, but in court the two follow different rules and produce different consequences for property and children.
How Molina Tightened the Standard
Two years later, in Republic v. Court of Appeals and Molina (G.R. No. 108763, February 13, 1997), the Court expanded the Santos framework into a detailed checklist that trial courts were expected to follow.4The Lawphil Project. G.R. No. 108763 – Republic of the Philippines v. Court of Appeals and Roridel Olaviano Molina Molina placed the burden of proof squarely on the petitioner, required the root cause of the incapacity to be medically or clinically identified and proven through expert witnesses, and demanded that the petition tie the incapacity to specific marital obligations under Articles 68 to 71. Any doubt had to be resolved in favor of preserving the marriage.
The practical effect was severe. Petitions without psychiatric or psychological expert testimony were routinely dismissed, and the cost of hiring qualified experts put the process out of reach for many Filipinos. Article 36 cases turned into quasi-medical proceedings.4The Lawphil Project. G.R. No. 108763 – Republic of the Philippines v. Court of Appeals and Roridel Olaviano Molina
How Tan-Andal Loosened It
In 2021, the Court reworked the framework in Tan-Andal v. Andal (G.R. No. 196359), acknowledging that the earlier interpretation had grown “restrictive, rigid, and intrusive on our rights to liberty, autonomy, and human dignity.”5Supreme Court E-Library. G.R. No. 196359 – Rosanna L. Tan-Andal v. Mario Victor M. Andal Three changes matter most.
Psychological incapacity was declared “purely a legal concept,” not a medical or psychiatric diagnosis. Expert testimony from psychiatrists or psychologists is no longer required; ordinary witnesses who can describe the spouse’s behavior and character may be enough. And the root cause no longer has to be shown as medically incurable. The inquiry now centers on whether the spouse’s “personality structure” makes genuine compliance with essential marital obligations impossible.5Supreme Court E-Library. G.R. No. 196359 – Rosanna L. Tan-Andal v. Mario Victor M. Andal
What Tan-Andal kept is the part of Santos that has always done the real work: gravity and juridical antecedence. The incapacity still has to be serious, and it still has to trace back to who the person was before the wedding.
Where the Rule Stands After 2024
In Dela Cruz-Lanuza v. Lanuza (G.R. No. 242362, April 17, 2024), the Second Division ruled that decades-long unjustified absence from the marital home can be weighed as part of the totality of evidence showing psychological incapacity.6Supreme Court of the Philippines. SC: Unjustified Absence from Marital Home Considered Psychological Incapacity That marks a real distance from the outcome in Santos, where Julia’s abandonment was treated as proving nothing on its own. The 2024 ruling does not make absence automatically equal incapacity. It treats a sustained refusal to perform any marital obligation as one piece of a fuller picture the court has to weigh.7The Lawphil Project. G.R. No. 242362 – Dela Cruz-Lanuza v. Lanuza
Read together, Santos, Molina, Tan-Andal, and Dela Cruz-Lanuza describe a standard that has moved from near-impossibility toward something a petitioner can actually meet. The Santos core survives. What has fallen away is the medical gatekeeping, the mandatory expert witness, and the clinical vocabulary. Philippine courts now judge psychological incapacity on the totality of the evidence, with the state’s preference for preserving marriages still weighing on the scale but no longer requiring a diagnosis before a court will act.
