The executed distribution agreement with schedules, the guarantee itself, any security or pledge documents, loan agreements and amortization terms, proof of ownership and value for pledged assets, and the transfer records tracing funds into the U.S. enterprise. Keep drafts and correspondence showing what was negotiated and when.
Match every dollar to a document
Build a simple table: date, amount, from which account, to which account, purpose, supporting document. Gaps show up immediately, and most can be filled afterwards with bank letters, notarized statements or contracts. Where funds passed through a personal account before reaching the business, keep both sides.
A schedule assembled this way also makes the guarantee easier to explain, because it shows which obligations relate to invested capital and which do not. Request the documents by name and in executed form: the distribution agreement with every schedule and appendix, the guarantee, any general security agreement or pledge, the registration search showing what is encumbered, each loan agreement with its amortization schedule, title or ownership evidence for pledged assets, and bank confirmations for every transfer into the enterprise. Ask for signature pages that are genuinely signed and dated, since an unexecuted counterpart is a frequent and avoidable gap.
Where a document exists only in draft, mark it as a draft in the schedule rather than leaving it unlabelled among executed instruments. Keep the negotiation correspondence in a separate folder; it explains why a clause reads as it does, which helps later and confuses if mixed with the final terms.
