After the Supreme Court's ruling in Tan-Andal v. Andal, expert psychological testimony is no longer indispensable to prove psychological incapacity under Article 36. The Court clarified that psychological incapacity is a legal concept, not strictly a medical illness, and that it may be proven by the totality of clear and convincing evidence, including the testimony of ordinary witnesses who observed the spouse's conduct. A psychologist's report can still help, but a case can now succeed without one where the evidence of the spouse's incapacity is strong.
For years, a common belief hardened into practice: to win an Article 36 (psychological incapacity) case, you needed a psychologist to examine the spouse and testify. The Supreme Court’s landmark ruling in Tan-Andal v. Andal significantly changed that.
What Tan-Andal Changed
In Tan-Andal, the Supreme Court reframed psychological incapacity and clarified how it is proven. Two shifts matter most:
- Psychological incapacity is a legal concept, not a medical illness. It need not be a clinically identified mental disorder; it is about a genuine, serious inability to understand and comply with the essential marital obligations, rooted in the person’s enduring personality structure existing at the time of the marriage.
- Expert testimony is no longer indispensable. Because it is a legal, not strictly medical, question, a case does not require a psychologist or psychiatrist to examine the spouse and diagnose a disorder. Incapacity may be proven by the totality of the evidence.
How Incapacity Is Proven Now
The standard is clear and convincing evidence of the spouse’s incapacity, drawn from the whole picture. Crucially, this can include the testimony of ordinary witnesses — people who knew the spouse before and during the marriage and can describe the persistent behaviors that show an inability to fulfill marital duties. Friends, relatives, and the petitioner themselves can supply the narrative of a durable, incapacitating dysfunction. The focus is on durable aspects of personality shown through conduct, not a clinical label.
So, Do You Still Need a Psychologist?
The honest answer: not necessarily — but it can still help.
- A case can now succeed without expert testimony where the lay evidence of the spouse’s incapacity is strong and well presented.
- But a well-prepared psychological evaluation can still add weight, organizing the behaviors into a coherent account of the personality structure and its roots. It is now corroborative rather than mandatory.
For litigants who could not afford a psychologist, Tan-Andal is a genuine opening — the cost barrier that stopped many valid cases is lower.
The Requirements Remain Demanding
Tan-Andal eased the mode of proof, not the substance. Psychological incapacity must still be shown to be:
- Grave — a serious incapacity, not mere refusal, difficulty, or incompatibility;
- Existing at the time of the marriage (juridical antecedence), even if it manifested later; and
- Incurable in the legal sense — enduring and persistent relative to the specific marriage.
A troubled marriage, irreconcilable differences, or a spouse who simply changed are not enough. The incapacity must be real, rooted, and serious.
Practical Advice
- You may be able to file without a psychologist, so cost need not stop you — but the lay evidence must be carefully assembled.
- Line up witnesses who knew the spouse before and during the marriage and can describe the incapacitating behaviors.
- Consider a psychological evaluation as optional reinforcement, especially in contested cases.
