Final answer:
The nephew who inherits his uncle's cattle ranch is legally known as a devisee, which is the term for someone who inherits real estate from a will.
Step-by-step explanation:
When a nephew inherits his uncle's 1,150-acre cattle ranch, the legal term that describes the nephew in this situation is a devisee. This term specifically applies to an individual who inherits real estate property under a will.
Other terms related to this process include bequest, which normally refers to personal property left to someone in a will; beneficiary, a broader term for anyone receiving property from a will or trust; and testator, which refers to the person who has made the will. In the case provided, the nephew would be considered the devisee.
The legal term for the nephew in this situation is devisee. A devisee is someone who is named as a beneficiary in a will and receives real property, such as land, as an inheritance. In this case, the nephew is inheriting the cattle ranch from his uncle.
