In order to avoid any future misunderstandings relating to your firm ceasing, for whatever reason, to provide services to a client, ICAEW considers it best practice to agree suitable terms of disengagement with the client. Wherever possible, terms of disengagement should be confirmed in writing in a suitably worded Disengagement Letter.
