What is an example of a monument in real estate?

A tree marking a boundary is considered a monument in real estate because it serves as a physical marker that helps delineate property lines. In land surveying and property descriptions, monuments are fixed objects that indicate the boundaries of a parcel of land. They can be natural or man-made features, and trees often serve this purpose if they were originally used to identify or establish a boundary.

The other options, while they may relate to property or boundaries, don't fulfill the specific criteria of a monument. Fences, signs, and walls typically do not provide the same historical or legal significance as a natural feature like a tree. In many cases, statutes or survey documentation reference monuments to provide clarity in property disputes or when defining land boundaries. This makes a tree an appropriate and representative example of a monument in real estate.
