Are you changing from one firm of solicitors to another?
The firm of solicitors that you are with now while the file is under their control. Nothing needs to be done with the court until such time as you decide if you are staying with that firm of solicitors or transferring to another firm in which case the new firm will file a notice of change of solicitors as soon as you instruct them.
Until you see the senior partner you can send a letter to your wife's solicitor requesting that until further notice all correspondence is to be sent to you personally.
