What is the name of your state? Pa. I am planning on cutitng some timber on my property. My neighbor is claiming that some of the trees are on his property. If I cut the trees and he sues me who has to prove where the property line is? My property has been surveyed a long time ago but you can not find the corner in question but the boundry side in question runs in a straight line. He is insisting that the line makes a turn.
