I would get your relative to seek legal advice - good as the CAB are, this is a specialist area. Quote ss28 and 29 of the Trustee Act and see if you can get the charges refunded to the estate. I would suggest that this is worth fighting (I have fought charges such as these when far less is involved). As a retired person, he cannot even claim loss of earnings. This is tantamount to a breach of trust, so will need to be properly pleaded with the appropriate enquiries by the court, and possibly even compound interest. Try and see a STEP or ACTAPs or Probate Section member if possible.
