The answer to your question depends on who you ask; some family lawyers take the position that once the other spouse moves out, you can change the locks on the house and prevent them from coming back; that's an interesting theory and  I would love to see their statutory or case  law legal theory to support that advice; my advice is different; you cannot change the locks on your house and prevent the other person from coming back, without a court order; routinely, within the first 30 days of the divorce, you can request a temporary court hearing, and the court can enter an order about changing the locks  on the house and giving exclusive possession to the non- vacating spouse. Courts do not like when parties engage in self/help remedies. The court can also order that the wife return any items removed from the home.
