Not long after my mother and I moved into the house she bought next door to our cousin, our cousin built a fence about 6 inches past our backyard fence onto our property. It made our driveway harder to turn into.
He claims that the people who built our's and our neighbors houses did not measure the land correctly, and thus, he actually owns about 6 feet of our property, half of our driveway. The landlord, of course, did not inform us of this little problem and claims my cousin is right.
But to make up for it, we apparently own all of our neighbors driveway right up next to their house. They don't know this, though. Like 8 feet.
I feel it's hard to believe the builders made that huge of a mistake twice, with two houses. My cousins son is a land surveyor and has offered his services, but obviously, I don't like that idea. Land surveyors cost way too much.
Is there another way to know? What can I do? Any thoughts?
