I hired a lawyer a few years back for a medical malpractice case against a doctor that I ended up injured from. The case resulted in us settling, now a few years later the lawyer I hired is telling me that WE are being sued for malicious procecution. I have not been served and I am being asked to sign An agreement that he is settling and paying them, Is my signature necessary. And am I responsible for any of it if I do or don't sign?
