Definitions for "Permanent and total disability"
A disability that will presumably last for the insured's lifetime and prevents engagement in any occupation for which the insured is reasonably fitted.
Total disability from which the insured does not recover. When used as a definition in a policy (usually a life insurance policy rider), "permanent" is presumed after a stated period of time, commonly six months.
A disability that is expected to last at least a year and keeps an individual from any gainful activity.
