My fiance's daughter and family live in his house (he has moved out of his house and in with me to allow their family a decent place to live; they were living in a trailer that was about to be condemned). He was going to sell the house, but agree to let them live there as long as they paid the mortgage and utilities, which remained in his name. They have defaulted mulitple times, and have run up immense utility bills which have gone unpaid as well, so that my fiance has had to work with the mortgage holder to stop foreclosure and is being taken to court by the utility companies. He's had as much as he can take and has warned them that he would take back the house if they continued to be delinquent; the final straw was the fact that he visited one evening to collect a few things that he had left there (again the agreement was that he would keep his personal belongings in the basement while he lived with me) and found that they had thrown almost all of his belongings (including irreplaceable items) into a dumpster to turn the basement into a play room for the children. He told his daughter he was taking back the house and they would have to move, and the next day she subsequently issued a restraining order stating he had "threatened them and their quality of life". (Fortunately we had witnesses there to attest that this is far from the truth). She lied on the restraining order and stated that she owned the property so he has been forbidden to go within 100 feet of it and cannot collect the remaining personal items.
My question is...is there a tenant/landlord agreement assumed here? (Not taking into consideration that she lied about her ownership). Once the hearing has taken place in a week on the restraining order, he wants the family out of the house...will he have to follow typical landlord/tenant laws?
Thank you!
