Is an Electronic Signature Legally Valid in Vietnam? (2026)

Yes. In Vietnam an electronic signature can be legally valid and can be used to conclude most business contracts. The main law is the Law on Electronic Transactions, which Vietnam updated in 2023 to replace the older 2005 law. The newer law came into force in 2024 and modernises how electronic signatures and electronic documents are treated. So the short answer is that a signature made by electronic means is recognised, but how much weight it carries depends on the type of signature and the kind of document. This is general information, not legal advice. The rules change and every transaction is different, so confirm the current position before relying on any point below. ## The law that governs e-signatures in Vietnam The Law on Electronic Transactions is the backbone. It sets out that information is not denied legal effect simply because it is in electronic form, and it recognises electronic signatures as a way to sign an electronic document. Around the law sit decrees and circulars on digital signatures and on the certification service providers that issue digital certificates, and these are supervised at the national level. <!-- [VERIFY] exact article numbers of the Law on Electronic Transactions 2023 (No. 20/2023/QH15) and the current implementing decrees before citing them as fixed --> In day to day business, the most trusted form is the digital signature backed by a certificate from a licensed certification service provider. Many Vietnamese companies already hold such a certificate because it is used for tax filing, electronic invoices and customs, so using it for contracts is a natural extension. ## Types of electronic signature recognised Vietnamese practice, like most modern frameworks, treats signatures on a scale of reliability. - A basic electronic signature is any electronic data attached to or logically associated with a document that shows who signed and that they approved the content. A typed name, a scanned signature or a click to accept can fall here. It is recognised but is easier to challenge if a dispute arises.

• A digital signature uses a certificate issued by a licensed provider and public key technology. It gives strong proof of who signed and that the document was not changed afterwards. For important commercial contracts in Vietnam this is the form parties usually want. <!-- [VERIFY] the exact signature categories named in the 2023 law and the licensing regime for certification service providers before stating them as definitive --> The practical rule is simple. The higher the value or risk of the contract, the more it is worth using a certificate-based digital signature rather than a plain click or a pasted image. ## What you usually cannot sign electronically Some documents are carved out or need an extra formal step such as notarisation or registration, so an electronic signature alone is not enough. These commonly include things like land and real estate transfers, inheritance and certain family documents, and papers that by law must be notarised or officially registered. <!-- [VERIFY] the precise list of excluded or notarisation-required documents under Vietnamese law before relying on it --> If a document has to be notarised or registered with a state body, treat electronic signing as the start of the process, not the finish, and confirm what the registry or notary will accept. ## How to make an electronic signature stand up in Vietnam Whether or not a signature is challenged later often comes down to the record behind it. 1. Match the method to the stakes. For routine or low value documents a basic electronic signature may be fine. For high value or regulated contracts use a certificate-based digital signature from a licensed provider.

2. Keep the evidence. Save the audit trail: who signed, when, from where, the version signed and how identity was checked. This is what proves consent if someone later denies signing.
3. Check the counterparty. Make sure the person signing has authority to bind their company, and keep a record of how you confirmed it.
4. Agree the method in the contract. A clause stating that the parties agree to sign electronically and will treat electronic signatures as valid removes a lot of later argument.
5. Confirm formalities. If the document touches land, family matters or anything needing notarisation or registration, check the extra steps before you rely on the electronic copy. ## How Vietnam compares The pattern in Vietnam is close to what you see elsewhere. The European Union uses the eIDAS Regulation with its qualified electronic signatures, the United States uses the ESIGN Act and state UETA laws, and India uses the Information Technology Act. In each, ordinary electronic signatures are valid for most contracts, a stronger certificate-based form is available for high trust use, and a short list of documents is excluded. Vietnam fits that shape, with the digital signature backed by a licensed certificate as its high trust tier. ## Keeping signing inside the contract workflow An electronic signature is only the last step of a contract. Before a document is ready to sign it has to be drafted, reviewed, negotiated and version controlled, and after signing it has to be tracked for renewals, obligations and key dates. When signing sits in one tool, drafting in another and tracking in a spreadsheet, the signed copy and its terms drift apart. Drafting, reviewing, signing and stamping, then tracking and governing a contract can live in one AI workspace tuned to how your company contracts. Adira is built around that workspace, running on Claude, with e-signing and e-stamping embedded in the flow, per-seat pricing shown up front and a 7-day trial, India-first and built to work across jurisdictions. A single legal-health view, the Command Centre, is on its roadmap. You can read more at adiralaw.com. For one signature the guidance above is enough on its own. The point worth keeping is that a signed contract is easier to rely on when the document, its signature trail and its key dates stay in one place.
