He’s not really a squatter. He was a guest. He lived there with permission of the owner. He should thank the owner for the 27 free years of no rent.
Well, he's been a squatter for the last 5 years since the owner told him to leave. Even a judge ordered him to leave several years ago. He claims the previous owner told him he could live there, but has no evidence. I agree, he should say thanks for the free livin, but I suspect he wants a handout, since he refuses to leave.
That is just his word against???????? We have no idea. Just because he said he had permission does not mean he had it.
