Your girlfriend likely should quickly find another attorney before her right to sue the other driver expires. My understanding is that in CA, the statute of limitations for actions on personal injuries is 2 years. The daughter's may have a longer time because she is a minor. Your girlfriend should consult and verify with an attorney licensed in the state where the accident occurred.
Attorneys are licensed and regulated by some agency. Attorneys have a code of ethics by which they must abide. The agency in CA is the California State Bar. The webpage for filing a complaint is: http://www.calbar.ca.gov/state/calbar/calbar_generic.jsp?cid=10179&id=1144 .
It is free to file a complaint. Whether your girlfriend will see any disciplinary actions against the attorneys depends on her facts.
Before filing a complaint, your girlfriend likely should take care of her injury claim lest her rights to sue expire.
Attorney Nguyen is right. Do you still need a lawyer? My office is in Bellflower so I am close. If you still need legal represention, or have any unanswered questions, I would be happy to speak with you.
