First, don't panic. The State Bar receives hundreds of complaints per month and many can be resolved without formal discipline. But do not ignore the State Bar. This is a big mistake many attorneys make.
Second, decide if hiring an attorney to assist you makes sense. The Rules of Professional Conduct and the State Bar Act are complicated and not well understood. Having counsel assist you with the response is a good idea in many cases. As a former Deputy Trial Counsel at the State Bar, I can tell you that attorneys often don't know how to respond and sometimes dig themselves into more trouble because they didn't reach out for help.
Lastly, there are options to resolve your investigation and complaint without formal discipline. A good defense counsel can negotiate and pressure the State Bar into either closing the complaint entirely or resolving the matter without formal discipline (which means your public record remains clear).
