Fundamental to a well-reasoned opinion on the location of property boundaries, also known as a survey of property, is being able to properly interpret a deed. Proper interpretation of a deed requires understanding uncertainty.
A deed that purports to convey real property contains many parts, and the land surveyor should have a working knowledge of all of them. But far and away the most important element of a deed to the formation of a well-reasoned opinion on the factual question of location is the description. In fact, many courts have defined a sufficient description of property as one that a reasonably prudent surveyor can locate on the ground.
