My wife that I am getting divorced from cancel my ins. And truck got stolen what for I do

Most divorce courts in Texas have issued standing orders that prohibit a spouse from cancelling insurance policies during the pendency of the divorce case.  If the court in which your divorce is pending has done so, you may be able to file a motion for contempt or a motion to enforce the standing orders.  With a motion for contempt, your wife can be fined or jailed for violating the court order.  With a motion to enforce, you may be able to persuade the court to give you from your community property a sum of money equal to the value of your truck when it was stolen to allow you to replace the truck.  I would argue that should be awarded to you before any other division of your community property as part of a just and right division because, but for your wife cancelling the policy, there would have been insurance proceeds to help you replace the stolen truck.
