Cal. Bus. & Prof. Code § 6203

(a) The award shall be in writing and signed by the arbitrators concurring therein. It shall include a determination of all the questions submitted to the arbitrators, the decision of which is necessary in order to determine the controversy. The award shall not include any award to either party for costs or attorney’s fees incurred in preparation for or in the course of the fee arbitration proceeding, notwithstanding any contract between the parties providing for such an award or costs or attorney’s fees. However, the filing fee paid may be allocated between the parties by the arbitrators. This section shall not preclude an award of costs or attorney’s fees to either party by a court pursuant to subdivision (c) of this section or of subdivision (d) of Section 6204. The State Bar, or the local bar association delegated by the State Bar to conduct the arbitration, shall deliver to each of the parties with the award, an original declaration of service of the award.
Evidence relating to claims of malpractice and professional misconduct, shall be admissible only to the extent that those claims bear upon the fees, costs, or both, to which the attorney is entitled. The arbitrators shall not award affirmative relief, in the form of damages or offset or otherwise, for injuries underlying the claim. Nothing in this section shall be construed to prevent the arbitrators from awarding the client a refund of unearned fees, costs, or both previously paid to the attorney.
(b) Even if the parties to the arbitration have not agreed in writing to be bound, the arbitration award shall become binding upon the passage of 30 days after service of notice of the award, unless a party has, within the 30 days, sought a trial after arbitration pursuant to Section 6204. If an action has previously been filed in any court, any petition to confirm, correct, or vacate the award shall be to the court in which the action is pending, and may be served by mail on any party who has appeared, as provided in Chapter 4 (commencing with Section 1003) of Title 14 of Part 2 of the Code of Civil Procedure; otherwise it shall be in the same manner as provided in Chapter 4 (commencing with Section 1285) of Title 9 of Part 3 of the Code of Civil Procedure. If no action is pending in any court, the award may be confirmed, corrected, or vacated by petition to the court having jurisdiction over the amount of the arbitration award, but otherwise in the same manner as provided in Chapter 4 (commencing with Section 1285) of Title 9 of Part 3 of the Code of Civil Procedure.
(c) Neither party to the arbitration may recover costs or attorney’s fees incurred in preparation for or in the course of the fee arbitration proceeding with the exception of the filing fee paid pursuant to subdivision (a) of this section. However, a court confirming, correcting, or vacating an award under this section may award to the prevailing party reasonable fees and costs incurred in obtaining confirmation, correction, or vacation of the award including, if applicable, fees and costs on appeal. The party obtaining judgment confirming, correcting, or vacating the award shall be the prevailing party except that, without regard to consideration of who the prevailing party may be, if a party did not appear at the arbitration hearing in the manner provided by the rules adopted by the board of trustees, that party shall not be entitled to attorney’s fees or costs upon confirmation, correction, or vacation of the award.
(d)
1. (1) In any matter arbitrated under this article in which the award is binding or has become binding by operation of law or has become a judgment either after confirmation under subdivision (c) or after a trial after arbitration under Section 6204, or in any matter mediated under this article, if: (A) the award, judgment, or agreement reached after mediation includes a refund of fees or costs, or both, to the client and (B) the attorney has not complied with that award, judgment, or agreement the State Bar shall enforce the award, judgment, or agreement by placing the attorney on involuntary inactive status until the refund has been paid.
2. (2) The State Bar shall provide for an administrative procedure to determine whether an award, judgment, or agreement should be enforced pursuant to this subdivision. An award, judgment, or agreement shall be so enforced if:
  1. (A) The State Bar shows that the attorney has failed to comply with a binding fee arbitration award, judgment, or agreement rendered pursuant to this article.
  2. (B) The attorney has not proposed a payment plan acceptable to the client or the State Bar.
    However, the award, judgment, or agreement shall not be so enforced if the attorney has demonstrated that he or she (i) is not personally responsible for making or ensuring payment of the refund, or (ii) is unable to pay the refund.
3. (3) An attorney who has failed to comply with a binding award, judgment, or agreement shall pay administrative penalties or reasonable costs, or both, as directed by the State Bar. Penalties imposed shall not exceed 20 percent of the amount to be refunded to the client or one thousand dollars ($1,000), whichever is greater. Any penalties or costs, or both, that are not paid shall be added to the license fee of the attorney for the next calendar year.
4. (4) The board shall terminate the inactive enrollment upon proof that the attorney has complied with the award, judgment, or agreement and upon payment of any costs or penalties, or both, assessed as a result of the attorney’s failure to comply.
5. (5) A request for enforcement under this subdivision shall be made within four years from the date (A) the arbitration award was mailed, (B) the judgment was entered, or (C) the date the agreement was signed. In an arbitrated matter, however, in no event shall a request be made prior to 100 days from the date of the service of a signed copy of the award. In cases where the award is appealed, a request shall not be made prior to 100 days from the date the award has become final as set forth in this section.
