I have a porperty on a lake that is approx 550 feet by 100 feet. I found out 2 years ago that my neighbors house is encroaching 2 feet onto my propert and has beed since 1984. I have owned the property for 3 1/2 years and my neighbor for 1 1/2 years. The neigh has approaced me twice about buying 5 feet of the property (5 by 550) because of his concernes about not being able to work on his house etc. I have told him I would deed him the portion of the land his house is encroaching on and give him an easement to allow him to work on his house etc. but I did not want to sell him 5 feet. I received a letter from him today asking to purchase 10 feet or that he would take it by adverse possession. Where do I stand? Does the fact he had owned it for 1 1/2 years have an affect? I am in Oklahoma and I understand that the law is 15 years for adverse possesion Does this mean the whole time the house has been encroaching or just the time he has owned his home. I really appreciate any infromation.
