The principal attorney in any lawsuit owes the duty of professional services at the standard of care to the attorney's client. Are you the client?
In a class action, the attorney owes a duty to the class, and the determination of who is in the class can be difficult over the course of the litigation.
Absent more facts about the nature of the case and legal proceeding, and about your connection and involvement in the legal matter and the underlying dispute, there is no basis for a more substantive and explicit answer.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
