What does "real property law" deal with?

Real property law primarily focuses on the ownership and use of land and any structures that are permanently attached to it, such as buildings and fixtures. This area of law governs various aspects including property rights, land use regulations, zoning laws, and the legal implications of property ownership. The term "real property" distinguishes it from personal property, which is movable and not fixed to one location.

In contrast to other choices, the focus on lease agreements for real estate transactions pertains more specifically to landlord-tenant laws, which are a subset of real property law but do not encompass the entirety of the field. Similarly, while all forms of property rights are significant, they extend beyond just real property, encompassing personal property as well. Lastly, the sale of personal property is entirely separate from real property law, which deals specifically with immovable property and interests related to land. Thus, choice A accurately captures the essence of real property law as it pertains to land and its permanent attachments.
