Definition - What does Incurable Insanity mean?
When the case of divorce is filed it is necessary for both the petitioner and the respondent to give the court their reason for seeking a divorce unless they are in a no fault state. Incurable insanity is one such reason where the basis of divorce is that one of the spouse is insane, and the condition is incurable.
Justipedia explains Incurable Insanity
Incurable insanity is a legal reason for divorce, but it is hardly ever used. This is because the difficulty involved in proving insanity at the time of filing the petition and the fact that it is incurable. To prove incurable insanity, it is important to prove that the alleged spouse has been in confinement for 3 years or has been declared incapacitated by a medical doctor.
