Not by itself. Distinguish the private service payment from the actual official transaction and case record.
Keep the receipt matched to what was paid
Retain the invoice and the corresponding government confirmation where applicable. Do not describe an amount held for future work or transfer as already received by the government without the real evidence. Hypothetical example: an exploration geologist pays a deposit described in the invoice as applied to the processing charge, and later cannot say whether the government has received anything.
Prevent that at the outset by asking for two distinct documents each time money moves: the adviser's own invoice or receipt for its services, and the official confirmation for anything paid under the process. Keep them in a single chronological file with a one-line note for each entry stating what was paid, to whom, on what date and on which instruction. Where an adviser holds funds pending an instruction, ask in writing where they are held, whether they are segregated, and what happens on withdrawal or refusal.
If a confirmation is delayed, record the request and the response rather than assuming the payment arrived. A private receipt describes an arrangement between the applicant and the adviser and cannot evidence a government transaction. Keep the file in one place from the first payment onward, because reconstructing it later depends on records other people control.
