The approval describes the facility; actual draw, transfer and receipt records show later events. Connect those records with the governing loan and investment terms.
Preserve the borrowing history
Explain the real borrower, obligations and relevant lawful-source information. Do not relabel the proceeds as accumulated savings or omit the debt because the funds passed briefly through a personal account. Preserve the borrowing history in the order it happened, and resist the urge to tidy it.
The application, the credit decision, the executed agreement, the security registration, each drawdown advice, each transfer confirmation, and the statements showing both sides of every movement together form a chain, and a chain is only as good as its weakest documented link. Where funds passed briefly through a personal account, keep that statement in the chain rather than omitting it, because an unexplained gap invites a worse inference than a documented detour. The origin of the borrowed money and the borrower's obligation to repay both belong in the file.
Hypothetical example: a land surveyor's file omits an intermediate personal account as a tidying step, and the missing statement becomes the only question anyone asks about it. Store the chain in one place under one naming convention, with each file named by date, payer and payee, so that anyone following it never has to ask which document comes next. A file order that has to be explained in a covering letter is an order that has already failed.
