Ending a client relationship is part of running a healthy firm, whether the fit is wrong, the client is unprofitable, or the risk is too high. Doing it in writing, professionally, protects you: it fixes the date your responsibility ends, closes off billing, and leaves a clean record if there’s ever a dispute.
Use the letter below as your standard disengagement template. Keep it factual and courteous, state the decision, hand over the records, and move on.

How to use this termination letter
Fill in the bracketed fields, delete anything that doesn’t apply, and keep the tone neutral, no matter the circumstances. Confirm your professional obligations for records retention and handover in your jurisdiction before sending. Send it in a way you can prove was delivered, and keep a copy on the client’s file.
For the harder question of when to let a client go and how to have the conversation first, read our guide on firing a client. To end the underlying contract cleanly, refer back to the termination clause in your client service agreement.
