The original share acquisition documents, the shareholder agreement, the buy-back agreement with the valuation and payment schedule, bank records of each payment, and the tax returns reporting the sale, all traced to the account that funds the investment.
Start with how the shares were bought
A share sale is only as clean as the share purchase behind it, so the file opens with the documents that made the investor a shareholder: an employee share plan and the payroll deductions that funded it, or a subscription agreement and the bank transfer that paid for it, together with the corporate register entries. Then the exit: the shareholder agreement's buy-back clause, the signed buy-back agreement, the independent valuation if one was obtained, and bank statements showing each instalment arriving. Hypothetical example: a Shannon engineer's buy-back is paid over three years by the remaining owners; the file must show every instalment and explain that the final payments are still to come, or wait until the full amount is in hand.
Personal tax returns for the sale years reconcile the capital gain. The inheritance stream needs the will, the notarial declaration of transmission or probate, the executor's accounts and the distribution deposit. Certified translations for French documents, and a summary table linking each stream to the escrow wire, complete the source section.
