If your husband took property that you have a rightful claim to, then this may be more than a divorce issue; that may constitute theft.

If they agree that there has been a theft, a criminal charge can be made and an arrest warranty issued. This depends a lot on what the "valuable possessions" were, how they were acquired and whether any belonged to you solely.
