If you have recorded a trust transaction incorrectly, you cannot edit the details, it must be cancelled.  To cancel a trust record:

1. Find the record in the Matter Trust tab or by going to Trust in the left navigation menu, then Trust Ledger.
2. Click on the Actions Menu.
3. Click on Cancel.
4. A window will appear:
   
   Enter a reason for the cancellation, and click Yes.

Once a trust record is cancelled, the cancellation reason is added to the description and a reversal record is created.  Cancelled trust records are coloured differently so they can be easily identified.
