California law expressly prohibits an attorney from settling a matter for his or her client without advance written consent. Otherwise, the client must sign any final settlement agreement or stipulated order. See LEVY v. SUPERIOR COURT, 10 Cal.4th 578 (1995)
You can contact your attorney and tell him that unless he immediately
moves to set aside the settlement (assuming that it's already entered by the judge), that you will contact the State Bar and ask for a formal investigation. And, you will contact a legal malpractice lawyer and sue for malpractice.
The judge's order can be set aside on grounds of fraud or mistake. However, before you start down the road of trying to "do-it-yourself" out of this predicament, you may want to contact your attorney and discuss the issue to make certain that the settlement as entered is not in your best interests.
I'm not trying to minimize the attorney's alleged violation of law or professional rules -- but, sometimes, economic reality must take precedence -- and you need to make certain that you're not shooting yourself in the foot by crying foul.
