Hired Attorney

Upon hiring Mark to take my case over from another attorney, I was given the utmost confidence from him that he "had me" and I had a 'simple' case, but it was anything but that. He did not communicate to opposing counsel, did not provide opposing counsel information that needed to be iterated from me, did not present them with options I provided, I once went 4 weeks without a work from Mark, despite blatant asks for updates. There were misspelled names of me and my child in court documents that I had to catch, inconsistent information across pleadings or documents, and an approach of "this is a slam dunk" but no real action being taken. Mediation settlement notes were not sent to opposing counsel, despite opposing counsel asking for updates. Come time for temporary orders, I got a call that the orders hearing was postponed (booked for 5 months) due to Mark and/or firm NOT FILING COURT REQUIRED PLEADINGS on time, despite being prepped for trial. This blew my case.
