The fact of a request does not itself establish a new charge. Check the notice and current official instructions before paying anything.
Distinguish evidence expenses from government demands
Record any professional, translation or document-retrieval costs separately and confirm their scope. If a message requests money, verify its origin and purpose. Do not assume an extra payment substitutes for the requested evidence or that an adviser’s response fee controls how the government will decide the issue.
Establish what is actually owed before anything is paid, since a request for evidence and a request for money are different things and only one of them arrives in a notice. Check the notice and the current official instructions before making any payment, and where a message asks for funds, verify its origin and purpose independently rather than through a link or number that message supplies. Record professional, translation and document-retrieval costs separately and confirm their scope in advance.
An additional payment substitutes for no part of the requested evidence, and an adviser response fee has no bearing on how the agency decides the underlying issue. Ask what the fee covers if a further request follows. Confirm any payment instruction through an official channel you located yourself.
Keep the verification note with the payment record afterwards.
