If purchase money is already in Thailand, ask the bank and Land Office which evidence they accept before reserving; fresh remittance proof may not fit the facts.
Short answer: A foreign buyer using Thai baht already held in Thailand should not assume the bank can issue a new overseas-remittance certificate for money that did not just arrive from abroad. Before paying, show the funds history to the bank and Land Office registering the unit and get transaction-specific guidance.
Create a dated file linking the source to the purchase: overseas transfers, Thai statements, documents from the earlier condo sale and transfer, closing statements and currency conversion. Keep names, dates and amounts consistent; map each account if funds moved through several.
A January 2026 DOL Q&A records a buyer’s question about prior condo-sale proceeds when the bank cannot certify a fresh overseas transfer. It does not give a universal document answer. Ask the receiving Land Office what it needs for this buyer, unit and registration, and the bank which records it can issue. Another buyer’s approval is not a precedent. Do not move money only to create paperwork before the bank explains how it will document the transfer.
Keep the reservation’s recipient, schedule, currency and refund conditions clear. Phuket Stay Pro can compare units; bring statements and the prior sale file to your bank and lawyer. See buying, ownership, due diligence and services.
Fact-check: DOL Q&A checked 18 October 2026. It records a question, not a binding answer. Bank and Land Office requirements vary; confirm before transfer.
