118. The voidable contract of a person non compos mentis may be ratified or avoided by himself when sane, or by his guardian during insanity, or by his representatives or heirs after his death.
119. The right to disaffirm is personal, and neither the other party nor third persons can avoid it.
120. In a few jurisdictions, although the other party did not know of the insanity and the contract was fair, the consideration received by the insane person need not be returned as a condition precedent to avoidance if he is unable to return it.
121. The contract can be avoided as against bona fide purchasers.
