The answer is: C
Explanation
The most accurate application of the principle in this scenario is option C:
C: A erred in setting aside C's money for fees without written permission.
Explanation:
The principle states that when an advocate receives money from or on behalf of a client, the entries in the accounts should indicate whether the amounts have been received for fees or for expenses. Furthermore, it explicitly mentions that an advocate may not divert any portion of the expenses towards fees without the client's written consent.
In the given scenario, A received money on behalf of the client C but did not obtain written permission to set aside the money as fees. While A noted in his accounts that he had received the money as fees, he made an error by doing so without C's consent. A should have properly accounted for the money as either expenses or fees based on the client's instructions or with their written consent.
Option C correctly identifies this error and reflects the violation of the principle. A should have acted in accordance with the principle and obtained the necessary written permission from C before setting aside the money as fees.
