I own some property that adjoins my brother’s property. He’s trying to sell his land now. He keeps saying that he "thinks" the line is here, this corner’s there, etc. He says that no survey is required, since there is a property description on file in the courthouse. Brother insists that he’s not laying out one dime for this property sale, and that the buyer can have it surveyed. I told him that nobody in their right mind would buy a piece of property where the boundaries aren’t clearly marked. He keeps saying it is buyer’s responsibility for the land survey. I know one of his corners is off by at least 20 feet, as I can remember the old property line from when I was a child. He’s a few years younger than me, and doesn’t want to hear what I’m telling him. If he does manage to sell it without a survey, what are my rights if the new owner and I disagree about where the property line is?
