We were buying our house, and in the process learned that the previous owner had made a home improvement that might have violated code and boundary lines. Our lawyer recommended we have a surveyor come to make sure we knew exactly where the land boundary lines were--the issue was literally down to the difference between a foot or two. The closing had already been delayed by a month because of the seller's mistake, and when we called Whitman they were quick and got us the information we needed.
