I don't owe him. We had a fixed fee that was agreed upon and I paid it in full in advance.
I've had a similar event where I paid a criminal defense lawyer a flat fee in advance.
I feel extreamly confident that a back alley deal had occured with the lawyer and the acusers witness. He's married and was sexually involved with the witness/subordinate coworker/lover. I've been told I have a malpractice action but the damages ar minimal and I can't find a lawyer to take it on.
