You need to do more than this. Why didn't y our attorney file the response in a timely fashion? You need to request that the court hear a motion to set aside the judgment under CCP 473. That requires the proper motion papers, a declaration stating the facts and a proper memorandum of points and authorities citing the proper statute and case law to support your request. You could also be required to pay the other side's attorney fees and costs to defend this motion. Even if granted, you will then be required to pay any court fees and costs to file your response. If you have waited a long time, then your task will be extremely difficult.
1. Form FL-300
2. Memorandum of points and authorities under Code of Civil Procedure 473(b)- Also check out Family Code 2122 grounds to set aside)
3. A detailed declaration to prove that the judgment was entered through surprise, inadvertence or excusable neglect.
This response will not create an attorney-client relationship between you and Sarieh Law Offices, and is not intended to serve as a legal advice in your specific circumstances. This response is a legal opinion based solely on facts represented and you should not rely on this legal opinion as a legal advice. You still need to consult an attorney directly to fully protect your legal rights.
You don't indicate which court the judgment was entered in, but you may need to prepare a formal motion.
MOST IMPORTANTLY: Before you go to the trouble of doing it, though, you should figure out WHY the judgment was more than what you "believed" was due. Did you have a written retainer agreement with the lawyer? Did you receive bills? Does the retainer agreement say that you'll owe interest if you don't pay on time? You won't be very happy if you spend the time, trouble and money to set the judgment aside, the court holds another trial, and the dollar amount of the judgment stays the same, or goes up. (Does the retainer agreement say that if you and the attorney go to court in a dispute about the fees, you'll have to pay his lawyer if you lose?)
