Start from the event that generated the funds, such as an asset sale, inheritance, or business distribution, and trace the ownership, transfers, and currency conversions from that point to the investment, preserving actual dates and amounts.
Explain gaps with records, not narrative alone
Identify who holds any missing documentation and what fact it is meant to establish. Where gifts, loans or distributions are involved, provide the actual governing agreements rather than a simplified summary. A clear explanation is useful, but it cannot substitute for a transaction record that does not exist.
The will or intestacy declaration, the death certificate, the estate inventory, the notarial or court documents naming beneficiaries and shares, the final estate accounting, the distribution record and the executor's contact details for a statement. The executed operating and subscription agreements, any promissory note, resolutions authorising the payment, the capital account ledger, distribution notices, and matching bank credits. The precise supporting documents depend on the funding history and current filing requirements; a single account statement rarely explains both origin and movement.
