What term describes physical property that crosses into a neighboring property owner's land?

The correct term for a physical property that crosses into a neighboring property owner's land is "encroachment." This term specifically refers to a situation where a structure, such as a fence or building, or a natural feature like a tree or its roots, extends beyond the boundary line of one property and intrudes into the space of an adjacent property. Encroachments can lead to disputes between property owners, as they can affect the use and enjoyment of each property and rights associated with land ownership.

Understanding encroachment is important in real estate and property law because it can influence property values, land use, and legal rights. Property owners usually have the right to take legal action if their property is encroached upon, depending on local laws and ordinances.

The other terms provided do not accurately describe this situation. Encumbrance refers to a claim or liability attached to a property, like a mortgage or lien, and equity generally relates to ownership interest or value in property after all liabilities are accounted for. Emblements are crops that are produced annually and can be harvested, and while they relate to land, they do not describe physical structures or properties that cross over into another property.
