As has been mentioned, unless it is otherwise agreed at the outset the client is personally responsible to his or her attorney for services rendered and calculated according to the retainer agreement.
However, it looks to me that there are some other factors that need your consideration. For example:
1. What was your understanding as to the hourly rate that your attorney would be charging you for his or her time?
2. Did the attorney discuss with you the likelihood that the court would award you your attorney fees?
3. Was it expressly understood that he would not be bound, or his charges limited to the amount awarded by the court?
4. Has the attorney presented you with an itemized billing accounting for the time charges?
5. Was he required to submit such an accounting to the court in order for it to assess fees against the other party? How does it reconcile with the billing you received?
6. Did the court arrive at the $2,000 or was it the attorney’s doing?
7. If it was an arbitrary figure set by the court, did the attorney make any effort to dispute it with the court?
8. What explanation has the attorney given you to justify the large discrepancy?
Obviously you are at a disadvantage in contesting the fee charges. And the only practical way you are going to level the playing field is to petition the Illinois State Bar Association in an attempt to have the dispute arbitrated. For information as to how to initiate that process start here:
