Ditto! I will not prepare and harvest a timber sale unless the landowner has a registered survey and can show me their property corners and boundarys.
That must really simplify your job
I would say all of that is unnecessary if adjoining landowners agree on the boundries. Here if there is an old boundry, i.e. and old fence line or corner posts, that is considered an appropriate boundry to go by. Even if one landowner doesn't agree, and even if it isn't actually the correct line, it is up to the land owner who disputes the line to obtain the survey and prove the old line is not correct.
Also, here where I live trespass laws are really geared to protect the landowner. You don't need your property fenced or even posted, it is totally up to anyone tramping around int he woods to know where they are at all times and whose land they are on, if your on someone elses land it is totally your fault, the landowner has no responsibilities in regard to making sure there boundries are marked or posted.
