Future... ugh! I just had some horrible gut feeling it would come to this. I assume somebody will have to initiate a Separation Agreement or Divorce Decree now that custody papers have been presented?
If you are going to retain the attny for the custody portion just get it all done at once. Do not go for anymore mediation or such BS. She took mediation WAS OFF the table when she hit you with these papers for custody. Sorry Charlie, her ship has sailed and now you go full steam with an attny.
Have your attny petition the court for immediate reimbursement for your legal fees. Do not fool around and just do it.
