What Documentation Should I Prepare to Support Fx Transfers?

Prepare clear documentation that shows who is sending funds, who will receive them, the purpose of the transfer, and the currency conversion details. Banks typically require a copy of the purchaser’s passport or ID, the buyer’s explanation for the payment (such as a property purchase), and a record of the source of funds. Ask your bank and your Thai lawyer which exact wording and documents they need before sending money. Keep a trail of emails or contracts that link the funds to a specific stage (deposit, contract signing, progress payments) and preserve exchange-rate quotes and transfer receipts. Avoid splitting or labeling transfers in ways that could cause registration or repatriation issues. This broader documentation helps prevent delays and keeps you ready for any audit or tax review.
