You want what yours and you want it now. We all do.
When it comes to real property, you may be getting more, or less than you bargained for - depending on what sellers and buyers agreed upon. In Idaho, it is important to have a property lines surveyed to ascertain the correct boundary lines before undertaking any project involving boundaries of real property. Assuming to know where the boundaries lie could result in one party losing some property and another gaining some property. In Idaho, if two adjacent landowners agree on the boundary line between their property, that may become the permanent boundary - even if it is not the actual property line. Even if the landowners do not know where the actual property line is located, and guess, it may constitute a binding agreement for the actual property boundary.
The mutually agreed boundary may become the permanent for all future purchasers. A simple survey could easily ensure that the boundary line is correct.
If you are buying property, hire a surveyor, first. If you have a dispute about your property lines, hire an attorney, first, and a surveyor, maybe, next.
