(b)

(1) Upon a determination that proceedings have been brought, prosecuted, or defended in whole or in part without reasonable grounds, the administrative law judge or the board may assess the adverse attorney's fee against the offending party.

(2) If any provision of Code Section 34-9-221, without reasonable grounds, is not complied with and a claimant engages the services of an attorney to enforce his or her rights under that Code section and the claimant prevails, the reasonable quantum meruit fee of the attorney, as determined by the board, and the costs of the proceedings may be assessed against the employer.

(3) Any assessment of attorney's fees made under this subsection shall be in addition to the compensation ordered.

(c) An attorney shall not advertise to render services to a potential claimant when he or she or his or her firm does not intend to render said services and shall not divide a fee for legal services with another attorney who is not a partner in or associate of his or her law firm or law office, unless:

(1) The client consents to employment of the other attorney after a full disclosure that a fee division will be made;

(2) The division is made in proportion to the services performed and the responsibility assumed by each; and

(3) The total fee of the attorneys does not clearly exceed reasonable compensation for all legal services such attorneys rendered to the client.
