What if I want to transfer the international application covered by my automatic debit order?

To terminate the automatic debiting procedure, the party withdrawing from the proceedings must explicitly revoke the automatic debit order under Automatic debiting management in Central Fee Payment (point 10.3 AAD). 

You must therefore do this at the same time as you request the transfer of rights.
