Yes. The actual arrangement includes relevant side agreements, not only the wording of the main document.
Compare every operative promise
Identify repayment rights, return terms and who can exercise them. Preserve executed versions and explain their relationship instead of omitting a conflicting letter from the analysis. A heading saying “at risk” does not erase an enforceable promise elsewhere, and a proposed cancellation should not be described as completed without evidence.
Documents proving both where the money came from and how it travelled: business financial statements and tax filings, sale or dividend records for whatever was liquidated, loan agreements with their security terms, and bank statements connecting each transfer from origin to the enterprise account. Start from the event that generated the funds and trace ownership, transfers, conversions and accounts through to the actual investment, keeping genuine dates and amounts rather than presenting a simplified summary. For a direct investment the capital evidence is the wire records into the company, the company’s bank statements showing the funds spent on the press, tanks, bottling line, lease improvements and working capital, purchase invoices, and financial statements for each year prepared by an accountant.
