I have a question for our INGO legal experts. Back story, my daughter, SIL and 3 grand kids currently live in a house that my wife and I own. They are living there rent free and there is no lease. Unfortunately, their marriage has deteriorated to the point that it may no longer be salvageable. If that time comes, I will want him out ASAP. He has a very short fuse and things could get ugly with him still there. Since there is no contractual arrangement, could he be trespassed immediately or would I have to begin eviction proceedings? We are trying to help them fix this mess, but if it goes south it probably will quickly and I would like know what my options are in advance.
