wow- that is horrible and I am sorry you are going through this. You are the homeowner and you have every legal right to restrict access. The problem is that your husband is the homeowner in theory as well, however it will sound pretty bad to the court if this person stays there, you may file a motion to have her vacate the premises or if she is breaking things the most expeditious way is to call the police and file a complaint for destruction of property and ask that she vacate that way. Good luck and I am sorry you are going through this.
