If your sisters are willing to  let you live there and pay the expenses of the house, fine. However, if they were to go to court, it is quite likely that a time would come that the house would be sold and you would no longer be able to reside there. You should consult with qualified counsel, as depending on the facts, there are several ways to deal with this problem.
