Which of the following actions transforms real property into personal property?

Severance is the act of detaching an item that was part of the realty, thereby converting it into personal property (e.g., removing a built-in fixture). Annexation is the opposite—attaching personal property so it becomes real property (a fixture). Emblements are annual crops treated as personal property by definition, not by a transformation act. A sale does not change the classification of items; it only transfers whatever is included (real or personal) as specified.
