Withdrawing the appointment of your migration agent
If you withdraw or terminate the appointment of your migration agent, they should advise the department in writing or using Form 956.
If Form 956 is used to notify the department, your migration agent will ask you to sign and indicate at Q24 (Declaration by Client) that they are no longer acting on your behalf.
If you appoint a new migration agent, they should notify the department using Form 956.
