Prudent Man Rule
The potential that the title to a real property interest will return to the original grantor or giver or to his/her lineal descendants. examples of events which could cause the title to revert: a gift of property to a hospital on condition that it be used forever for health care, but if the building is no longer used for that purpose the property will revert to the family of the original grantor; the real property is given to a daughter and her children, but will revert to her brother’s descendants if her line dies out without further issue.
