A marriage is voidable if either party was of unsound mind at the time of the marriage celebration, because valid consent requires a sound mind. The insanity must have existed at the very time of the marriage; a person who was sane when they married but became insane afterward has no ground on that basis. The action to annul on this ground may be filed by the sane spouse who had no knowledge of the other's insanity, by a relative, guardian, or person having legal charge of the insane party at any time before the insane party's death, or by the insane party during a lucid interval or after regaining sanity. A crucial bar: the sane spouse who, knowing of the insanity, freely cohabited with the other after the latter came to reason, is deemed to have ratified the marriage and can no longer annul it. This is distinct from psychological incapacity under Article 36, which makes a marriage void, not merely voidable.
Valid marriage consent requires a sound mind. If a spouse was of unsound mind at the time of the marriage, the marriage is voidable.
The Ground
A marriage is voidable if either party was of unsound mind at the time of the marriage. The reason: a person without a sound mind cannot give the intelligent consent that marriage requires.
The Insanity Must Exist at the Marriage
Critically, the insanity must have existed at the very time of the ceremony. A spouse who was sane when they married but became insane afterward has no ground on this basis — the defect must be present at the moment of consent.
Who May File
- The sane spouse who had no knowledge of the other's insanity;
- A relative, guardian, or person having legal charge of the insane party, at any time before that party's death; or
- The insane party during a lucid interval or after regaining sanity.
Ratification Bars the Action
An important bar: the sane spouse who, knowing of the insanity, freely cohabited with the other after the latter came to reason, is deemed to have ratified the marriage — and can no longer annul it.
Not the Same as Article 36
Do not confuse this with psychological incapacity (Article 36), which makes a marriage void, not merely voidable, and refers to an incapacity to comply with essential marital obligations, not clinical insanity.
Practical Takeaways
- Unsound mind is a voidable-marriage ground — the insanity must exist at the time of the marriage;
- The sane spouse, a guardian/relative, or the insane party (when lucid or recovered) may file;
- Free cohabitation after the party regains reason, with knowledge of the insanity, ratifies the marriage — and it differs from Article 36.
