What term refers to the degree, quantity, nature, and extent of interest a person has in real property?

The term that refers to the degree, quantity, nature, and extent of interest a person has in real property is "estate in land." This concept is fundamental in real estate as it describes the legal rights associated with property ownership. An estate in land encompasses various forms, such as freehold estates and leasehold estates, representing the different ways an individual can possess or control real property. It indicates the type of ownership (such as full ownership or a temporary right), the duration of the ownership, and any limitations or conditions that apply.

Understanding estates in land is essential for real estate professionals because it affects how properties can be bought, sold, inherited, or transferred. This knowledge is crucial for effective property management and ensuring compliance with various laws related to real property ownership.

In contrast, evidence of title refers to documentation that proves ownership of a property but does not pertain to the nature or extent of interest itself. Ethics signifies moral principles guiding behavior but is not related to property interest. Estoppel is a legal principle that prevents someone from arguing something contrary to a previously established position or statement but doesn't deal directly with property interest either.
