Non-Assignable contracts simply means a form of contract including a lease or license that is not assignable without receiving a consent from the third party. In any case such consent has already been acquired but the assignment has been left attempted, it would result into some breach of contract, a lease or license or may it be otherwise left unimpeached without receiving any prior consent upon the same (MacMahon, 2020). Moreover, based on the area of law, that is both non-transferable as well as non-assignable one would be able to consider it even it comprises of various meanings. For example, as of the probate or estate law, the terminology non-assignable simply means that any contract or agreement cannot be simply assigned or passed onto the heir.
