Hi - my name is XXXXX XXXXX I'm a litigation
attorney. Thanks for your question. I'll be glad to assist you with this issue, which is a complicated one.
What the attorney holding the money SHOULD do is file an interpleader lawsuit, and turn the money over to the court clerk - - and the clerk will hold the money until a court decides how to disburse it. Basically, the attorney would inform the court that there is a disagreement between the members of the LLC and that the money is being turned over to the court clerk until the judge orders how to disburse the funds. That gets the lawyer out of the predicament, and gives the members of the LLC to make their cases for the money.
IF your bylaws state that majority rules, then you should be able to successfully recover the money via court order. This can happen fairly quickly if the interpleader is filed and an emergency hearing is requested by the parties, etc. Thus, you can act fast on this.
Also, the bar is not going to force him to turn the money over. You can file a complaint against the attorney, but that's not going to do anything to force him to act. However, the interpleader will get the money and the parties before the court fairly quickly.
