Which term refers to the act of attaching personal property to real property?

The term that refers to the act of attaching personal property to real property is annexation. This process involves physically attaching or incorporating personal items, such as fixtures, to the real estate, making them part of the property. When personal property is annexed, it typically becomes part of the real property and is subject to the same legal rules and considerations, such as sale, transfer, or encumbrance.

Understanding annexation is crucial in real estate because it clarifies the distinction between personal property and real property. For example, if a homeowner installs new light fixtures, those fixtures become part of the house and are therefore considered real property through the act of annexation. This concept not only influences ownership rights but can also impact property valuation and the rights of buyers and sellers during transactions.

Other terms mentioned, such as conversion, affixation, and attachment, while related, do not specifically define the process of incorporating personal property into real property in the same legal context. Hence, annexation is the most accurate and directly applicable term in this situation.
