He can not have your records subpoenaed unless he has filed a suit against you and in the course of that law suit his attorney requests through deposition and discovery a copy of those records and your attorney agrees to supply them. It is very expensive to start a law suit and get to the point that documents are subpoenaed so he must be willing to make a big investment in attorney and court fees if he wants access to these records.
