I am the plaintiff in a personal injury lawsuit in California. The defendant is the owner of the building where I sustained the injury. At a hearing that was to decide whether to go to trial or reach a settlement I decided to orally accept a settlement before the judge because I felt pressured from all parties including my attorney. After reflecting on it I've changed my mind & would like to pursue a trial. I have not signed anything accepting the settlement. My attorney has told me that I can't change my mind & listed CCP 646 as the reason why. Do I still have the choice not to accept & sign the settlement to pursue a trial?
