text: what are the grounds for suing your divorce lawyer?   you can generally file a bar/judicial board complaint against your attorney for: 1. incompetence 2. unethical behavior 3. failure to perform the duties a lawyer must perform according to your state's attorney's ethical code. (one example: taking a client's money and doing nothing and/or failing to do that which was agreed to do in the attorney-client contract or retainer agreement)  you can generally only sue if you suffered some type of measurable damage or economic loss or seek some type of injunctive relief.
