You should hire a new lawyer ASAP. Best wishes to you.
Although AVVO describes this site as providing free legal advice, it is really a simple Q&A forum. The volunteer attorneys provide general answers. No specific legal advice is given here and no attorney-client relationship is established. For precise direction and legal advice, please consult in person with an attorney in your area. Be sure to bring all relevant paperwork with you.
Depending on the situation, that lawyer may have had a duty to disclose that conflict to you quite some time ago. You should absolutely mention that to your next lawyer, as there may be a case for legal malpractice against your old attorney.
