What is the term for the transfer of real property under a will?

The term for the transfer of real property under a will is referred to as a "devise." In legal terminology, when a will specifies that a particular piece of real estate is to be transferred to an heir or beneficiary, it is said that the property is bequeathed via a devise. This term is specific to real estate, distinguishing it from other types of property transfers that may be referred to differently.

While the other options represent various concepts related to property transfer, they do not specifically refer to transfers made through a will. A grant typically refers to a transfer or conveyance of property rights but lacks the direct connection to testamentary context. Distribution generally relates to the allocation of an estate's assets after death, which can include both real and personal property, but does not specifically denote the action of transferring real property under a will. Conveyance is a broader term encompassing various methods of transferring property but does not designate the specific operation of doing so through a testamentary document. Hence, devise is the most precise term for this scenario.
