You can file an application/motion with the court requesting that the court order your husband to cooperate with completing the passport application, including by signing any necessary documents and doing so by a particular date or in a timely manner.  If you are filing an application in court against your husband for the first time, you may fill out the packet located at this web address: http://www.judiciary.state.nj.us/prose/11492_fd_initial_appl_kit.pdf The packet includes instructions for how to complete it.  There is no filing fee for a non-dissolution application/motion.  If you already have a court order and you want to modify it along with your request that the court order your husband to cooperate with completing the passport application, you may use the packet located at this web address: http://www.judiciary.state.nj.us/prose/11487_fd_appl_mod_kit.pdf This packet also includes instructions for how to complete it.  A non-dissolution application to modify an existing order requires a $25 filing fee.
