In cases where property lines are disputed by their respective owners, the first step, obviously, is to consult with the most accurate maps to determine proper ownership. The line should then be redrawn and enforced. In cases where the disputed boundary is between two states, and the affected existing property owners have assumed to have resided in one state whereas the new mapping shows the property to truly belong to the other state, attempts should be made to get the owner to agree to change. However, if the owner desires, that owner may continue to use their existing social services (utilities, local schools, post office, hospital, etc.) until the next occupant of the property moves in. All new sales or renting of the property would require full placement of that property in the correct state.
