Halmon L. Banks III, who had been a partner at the workers’ compensation firm formerly known as Martin Banks until his acrimonious departure last month, has opened Banks Law, his own three-lawyer firm.

The move comes about three months after Banks, while still a partner at Martin Banks, filed a suit claiming the other partners at the firm had taken steps to drive him out of the firm, including steering big cases away from him, firing his paralegal without his consent and limiting his access to the firm’s case management software.
