The counsel's fee for services may not be contingent upon the securing of a dissolution of marriage, upon obtaining custody, or be based upon the amount of maintenance, child support, or property settlement received, except as specifically permitted under Supreme Court rules. The counsel may not require a non-refundable retainer fee, but must remit back any overpayment at the end of the representation. The counsel may enter into a consensual security arrangement with the client whereby assets of the client are pledged to secure payment of legal fees or costs, but only if the counsel first obtains approval of the Court. The counsel will prepare and provide the client with an itemized billing statement detailing hourly rates (and/or other criteria), time spent, tasks performed, and costs incurred on a regular basis, at least quarterly. The client should review each billing statement promptly and address any objection or error in a timely manner. The client will not be billed for time spent to explain or correct a billing statement. If an appropriately detailed written estimate is submitted to a client as to future costs for a counsel's representation or a portion of the contemplated services (i.e., relative to specific steps recommended by the counsel in the estimate) and, without objection from the client, the counsel then performs the contemplated services, all such services are presumptively reasonable and necessary, as well as to be deemed pursuant to the client's direction. In an appropriate case, the client may pursue contribution to his or her fees and costs from the other party. (6) DISPUTES. The counsel-client relationship is regulated by the Illinois Rules of Professional Conduct (Article VIII of the Illinois Supreme Court Rules), and any dispute shall be reviewed under the terms of such Rules.
