I hired a lawyer for an abuse case against a nursing home. While I was away he gave some wrongful advice to one of my family members. My family member got into my checking account thinking it was okay because it was on our dad's account. But what they failed to realize it was a "joint account with survivorship and not for tenants in common". I have already filed a complaint with the FDIC about the bank. What is the legal way to deal with my lawyer?
