can you sue your attorney before the case goes to trial

The easy answer is "yes." However, once you sue the lawyer, the lawyer will have good cause to withdraw from your husband's case.  Your husband will likely need to get a new attorney and the 3-9-2016 trial date will likely go away.  Depending on the court's schedule, a new trial might not be scheduled for 60 days or longer. Also, depending on the judge, the lawyer's motion to withdraw could be denied. I am not saying that you should not raise these issues with the lawyer and demand answers.  Your husband is entitled to competent defense. I recommend demanding a meeting with the lawyer and your husband and ask for documentary proof rom the lawyer as to what has been and not been happening.  Once you have answers, then you can decide how to proceed.
