If you have a Court Order for Spousal Support, then you can file for Contempt of Court due to his non-payment of the court ordered support. If you just separated and don't have court orders yet, you need to file a Request for Orders for Spousal Support and wait for your court hearing for the Judge to determine if there should be support ordered and how much.
