Unfortunately the IRS views the debt as a joint and several liability. In other words, they don't care who they get the money from as long as they get it. Depending upon your financial information and the amount of taxes and penalties involved, you might try an Offer in Compromise to see if you can pay it off for less. You could also file a civil suit against your ex for monies you paid against what you claim is his debt.
You do need a lawyer to help analyze and help you with this.
