Chiefly professional time and document retrieval: certified translations, archived bank statements, accountants' letters, valuations and additional legal hours spent reconciling records across jurisdictions. None of that counts towards the qualifying capital. Budget for it separately, and expect the figure to grow with the number of sources, countries and years being explained.
Ask how translation and tracing work is billed
Find out whether translation is charged per page, whether the adviser reviews bank records hourly or at a fixed price, and what happens if a new source has to be documented mid-preparation. Ask what a response to a government request for further evidence would cost, since funding questions are a common subject. Confirm government filing fees near the filing date.
Keep these amounts outside the capital, which is exposed to the business itself. Ask one more question about scope: what happens to the fee arrangement if a source has to be abandoned. Funding histories change under examination — a record proves unobtainable, an account turns out to be jointly held, a transfer cannot be explained by anyone still living — and replacing a source part-way through means work already done is written off.
Establish in advance whether that is billed again, and whether an initial review of the proposed sources can be bought separately before the full engagement begins. Hypothetical example: an investor commissions a two-week review of four candidate sources before instructing anyone on the petition itself, and that review eliminates two of them, which is a considerably cheaper way to learn it than discovering it at exhibit ninety.
