A survey does not automatically split a parcel of land. Most surveys are done to locate buildings on a parcel of land for mortgage purposes or to determine lot lines for putting up fences. A survey will be required when building a structure on a parcel of land.
A specialized survey called a certified survey map (CSM) will split land once it is recorded with the Register of Deeds Office. A CSM constitutes property that has been surveyed by a Registered Land Surveyor and has been approved by appropriate units of government.
