Signing via email, ticking "agree" on a digital platform, remote digital signing — e-contracts are everyday business practice. From 1/7/2024, the 2023 Law on E-Transactions (20/2023/QH15) replaced the 2005 law with a fuller framework. Key points for businesses:
1. What the new law changes
The 2005 law was born when e-commerce was nascent. After nearly 20 years, the 2023 law (effective 1/7/2024) comprehensively updates:
- Detailed e-signature categories: digital signatures, dedicated e-signatures and others — instead of generic rules.
- Clear legal validity of data messages — the foundation of every e-contract.
- New rules on e-contracts and trust services (signature certification, timestamps…).
- Clarified exclusions from e-transactions.
2. What is an e-contract and when is it valid?
An e-contract is a contract formed as a data message — information created, sent, received and stored electronically (email, e-signing platforms, contract management systems…).
For validity, e-contracts meet the general contract conditions (capacity, voluntariness, lawful content) plus specific ones:
- The parties agree to use electronic means (unless otherwise provided by law);
- The data message assures integrity (unaltered except ordinary technical changes), and is accessible and usable when needed;
- Any e-signature used meets statutory conditions.
In short: a compliant e-contract has the same legal validity as a paper contract.
3. E-signature vs. digital signature: don't confuse them
- Electronic signature is the generic concept: any electronic data attached to a data message to identify the signatory (scanned signatures, OTP codes, screen-drawn signatures…).
- Digital signature is the highest-grade e-signature: created with a private key corresponding to a public key in a certificate issued by a licensed certification provider. The law presumes digital signatures meet the validity conditions.
Practice: for high-value contracts, new counterparties, or anticipated disputes — use digital signatures. For internal dealings and familiar partners, other e-signature forms still work if the statutory conditions can be proven.
4. Cases EXCLUDED from e-transactions
The law excludes sensitive areas, mainly:
- Issuance of land-use right and house-ownership certificates;
- Inheritance documents;
- Marriage registration and divorce decisions;
- Certain civil-status and notarization documents.
Ordinary commercial and civil transactions (sale of goods, services, loans, distribution…) may all use e-contracts.
5. Storage and evidence: where businesses get complacent
Paper contracts go in a safe; e-contracts need a matching "digital safe":
- Store on systems with access logs, permissions and periodic backups;
- Preserve metadata (signing time, IP addresses, system logs) — evidence of integrity;
- Prefer timestamps from licensed trust-service providers for important contracts.
In disputes, data messages are recognized as evidence where authenticity and integrity are assured. Carelessly stored e-contracts (files in personal email, no logs, no backups) carry very weak evidential weight.
6. E-contract implementation checklist
- Issue internal regulations on e-contracting (who may sign, signature forms, approval workflows).
- Choose a reputable e-signing platform with licensed certification.
- Standardize e-contract templates with electronic-means and signature clauses.
- Set up storage systems with logs, backups and permissions.
- Train staff — especially authorized signatories.
- Review the latest implementing guidance for the 2023 law before embedding it in processes.
7. E-signature rollout checklist for SMEs
Going electronic is not just buying a digital certificate — it is a 6-step process many SMEs get in the wrong order:
Step 1 — Map which contracts may be electronic. The law excludes certain transactions from electronic form (e.g., some land-use right and housing transactions, wills, marriage registration…). List the contracts your company routinely signs and flag which ones still require paper.
Step 2 — Match signature type to transaction value. Public digital signatures (issued by licensed certification authorities) carry the highest legal value — use them for high-value contracts and dealings with state authorities. Basic e-signatures (OTP, click-to-sign) suit internal, low-value transactions. Never use a scanned image of a handwritten signature pasted into a PDF for important contracts — its evidentiary value is very weak.
Step 3 — Issue internal rules on e-signing authority. Who may hold a corporate digital signature? Signing limits? Pre-signing approval workflow? This is the safety valve against employees binding the company unilaterally.
Step 4 — Standardize the e-contract template. Add clauses on: the parties' agreement to contract electronically; the time of formation (when the data message is sent/received); the place of formation; and how the electronic original is stored and by whom.
Step 5 — Storage and retrievability. Data messages must be stored with integrity and be retrievable on demand — lose the original file or fail to prove integrity, and the e-contract loses evidentiary value. Use timestamped storage services with periodic backups.
Step 6 — Train and rehearse. Train sales and accounting teams on the signing workflow; rehearse scenarios like certificate expiry and revocation when staff leave.
Practical note: Revoke digital certificates on the employee's last working day — orphaned certificates are the most common source of signature fraud. Also calendarize renewal 30 days before expiry: an expired certificate invalidates later signatures, and counterparties have successfully challenged contracts signed during the gap. For cross-border e-contracts, confirm the counterparty's jurisdiction recognizes Vietnamese e-signatures, or use a mutually agreed platform with its own evidentiary trail. Finally, test the full signing flow with a low-value internal document first — discovering a workflow flaw on a major client contract is an expensive lesson. Assign one owner for the e-signature system — shared responsibility means nobody monitors expiries.
FAQ
Q: Do e-contracts have the same validity as paper contracts?
A: Yes, if statutory conditions are met: agreed electronic means, integral and accessible data messages, valid e-signatures (2023 Law on E-Transactions, effective 1/7/2024).
Q: Can e-signatures replace handwritten signatures?
A: Yes, when statutory conditions are met. Digital signatures (licensed-provider certificates) are presumed compliant and most reliable.
Q: How does the new law differ from 2005?
A: Detailed e-signature categories, clear data-message validity, new e-contract and trust-service rules, clarified exclusions.
Q: Which cases cannot use e-contracts?
A: Land/house certificate issuance, inheritance documents, marriage registration, divorce decisions, certain civil-status/notarization papers.
Q: What serves as evidence in e-contract disputes?
A: Data messages (contract files, emails, logs, digital signatures…) recognized as evidence where authentic and integral — hence proper storage and digital signatures.
