My question involves malpractice by a lawyer in the state of: California
I was the Plaintiff in a 4 year battle, where we finally settled for a 6 figure number.
Myself and my attorney signed the settlement agreement, agreeing to not disclose the existence of a settlement.
My attorney posted on the internet, bragging about settling, naming the Defendant, and the defendant is so far successfully arguing that the settlement agreement was breached, and has stopped all payments.
We are waiting for arbitration to decide, it's been a long time since I was supposed to receive money.
If we lose, do I know have to face suing my attorney? If so, do I sue for the settlement amount or for more?
Do lawyers have malpractice insurance?
Do I get the Bar involved?
If we win, do I have an argument for less attorney fees for the hassle?
Any guidance is appreciated!
