With the share purchase agreement, the lender's commitment letter to the buyers, the closing statement, the deposit record, and the years of corporate financials and tax returns that show the company was lawfully built. The gravel-pit sale is documented in parallel with its deed and tax filing.
Show the company's history as well as the sale
Source of funds for a business sale has two parts, and sellers often prepare only the second. The first part is proof that the company itself was lawfully owned and built: incorporation documents, the share register showing his ownership over the years, financial statements and corporate tax returns, and personal returns showing the salary and dividends he drew. The second part is the sale: the share purchase agreement with the three employees, the bank's financing commitment letter that explains where the buyers' money came from, the closing statement, and the bank record of the proceeds arriving.
The gravel-pit sale gets the same treatment with the acquisition deed, the sale deed, the notary's statement of adjustments and the return that reported the gain. Then the path: statements showing the funds in his accounts, any transfer to a joint account, conversion confirmations, and the wire to the escrow or the new commercial enterprise. Translate every French document the narrative relies on.
