Your situation is nothing like his. You had a trespass issue, not a contract issue. As for spending 5 years dealing with lawyers, that was your mistake. You should have just leveled the building if you knew without a doubt that it was on your land, or you could have just taken possession of it. If he had been living there full time, that would have been another matter, since you would have had to evict him. As you said, he had a place elsewhere, so that wasn't an issue. If someone builds a structure on your property, with or without your permission, the structure belongs to you. Once it is built on the property, it becomes "real" property, and ownership is with the land owner, unless there is a contract that says otherwise. If I had been in your situation, I would have cleaned out all personal possessions of the squatter, and just secured the building for my own use. I also would have left the electric poles to service the building. Depending on the type of electrical service that was there, the poles might have belonged to the power company, and even though you own the land, the power company never conveys ownership of the poles to the land owner. If the power company charges you to install poles, the charge is just for the installation, not the poles themselves. Didn't it worry you a little bit knowing that you were cutting electrical poles with live wires strung on them, or had the service been interrupted ????
