To give you the most accurate answer, could you tell me what type of documents you plan to use with Signify? That will help me explain exactly how it works for your needs.

In general, electronic signatures are fully legal in Vietnam under the Law on E-Transactions (2005). For most business documents like contracts, NDAs, employment agreements, supplier deals, invoices, or internal approvals you can use e-signatures safely, as long as both sides agree to sign digitally and the signer’s identity can be verified.

A few government-issued documents still require physical signatures or notarization, such as land ownership transfers, marriage certificates, or other official state records.
For everyday business use, Signify works perfectly. And it’s not just for signing you can also manage, share, and track all your documents and team workflows in one place, keeping everything organized

My type of documents is "Driver Training Contract"

Yes, it’s completely legal. For a Driver Training Contract, an electronic signature is valid as long as both parties agree to sign digitally and the signer’s identity can be verified, for example using our video identification.
