Vietnam

When a young couple in Vietnam buys their first apartment, the down payment often comes from parents, uncles, and close friends rather than a bank. Hui circles — rotating credit groups among colleagues or market vendors — remain a living tradition, and lending within the extended family is simply how big purchases get made. These arrangements run on family duty and face, which means they are rarely written down.

Yet Vietnamese practice has always respected paper for serious matters. A giấy vay tiền — a simple handwritten or printed loan paper stating who borrowed what, when, and on what terms — is a familiar document, and for significant transactions people commonly have documents certified at the local ward or commune office. Applying that same care to a family loan takes ten minutes and can preserve both the money and the relationship.

Payment habits are shifting fast from cash to bank apps and QR transfers. That shift quietly helps lenders: every transfer carries a timestamped record, and the content line of a Vietnamese bank transfer can state exactly what the money is for — a small habit that produces surprisingly strong evidence.

Common signing methods

• Wet-ink signatures from both parties, sometimes on every page of longer documents — the standard for personal loan papers in Vietnam.
• A thumbprint pressed beside the signature, a common Vietnamese practice that adds a second layer of identification to important documents.
• Certification of significant documents at the local ward or commune office, a familiar step for transactions people want to make official.
• Digital signatures backed by certificates, widely used by businesses; individuals increasingly sign PDFs on their phones for smaller arrangements.
• Confirming terms over Zalo chat — not a signature, but messages stating the amount and repayment date are commonly saved as supporting evidence.

Witness guidance

• Witnesses are not generally required for a private loan paper to bind the parties in Vietnam, but within families a senior relative often witnesses the arrangement, which carries both social and practical weight.
• For loans between friends or business acquaintances, one or two neutral adults who watch the signing and add their names strengthen the document considerably.
• Record each witness's full name, ID details if they are willing, and contact information directly on the document.

Electronic signatures

• Vietnam has an electronic transactions law that generally recognizes electronic signatures, and certificate-backed digital signatures are well established in Vietnamese business life. Personal lending, however, still mostly happens on paper.
• If you sign electronically, keep the original file untouched, record when and how each person signed, and save the conversation around the signing. FinSafe cannot guarantee any e-signature will be accepted in a specific Vietnamese dispute.
• For large family loans — the kind that fund an apartment or a business — a printed, ink-signed document, ideally with a thumbprint and a witness, remains the most conservative choice.

Example

• Dong amounts involve many zeros, so always write the sum in words as well as figures — 200.000.000 VND (hai trăm triệu đồng) — to keep one missing zero from becoming a catastrophe.
• Use the transfer content line deliberately. A bank transfer whose note says it is a loan disbursement or a repayment for a named agreement is far better evidence than an unlabeled transfer.
• Dates are written day first (DD/MM/YYYY). Write the month in words on important documents shared with foreign parties.
• Keep bank app receipts, e-wallet records, and Zalo messages together with the signed paper — the combination tells the full story of the loan.
