Land surveys can be expensive, but they're helpful if you're concerned about neighbors encroaching on your land or of timber theft. They're also important if you want to build a new structure, install a fence, or just know where your boundaries are so you can mark them.
This website lists 5 steps to getting a survey done on your property. Note that surveyors don’t normally mark boundary lines; you’ll need to specifically request that from yours.
This New York State Association of Professional Land Surveyors website lets you locate surveyors by city or county.
