Under the Hindu Marriage Act, 1955, a person suffering from mental disorder can marry only if:

Section 5(ii) requires that neither party is incapable of valid consent through unsoundness of mind, nor, "though capable of giving a valid consent, has been suffering from mental disorder of such a kind or to such an extent as to be unfit for marriage and the procreation of children", nor has been subject to recurrent attacks of insanity. Disclosure, court permission or family consent does not cure the defect.
