Scenario: your landlord insists the lease “must be notarized to be valid” — and offers to take you to a notary office, fee on you. Is notarization actually required? No. But the confusion is widespread, so here is the exact rule, its limits, and when notarization is still worth paying for.
The rule: no notarization required (Housing Law 27/2023/QH15)
Under current law, a residential lease contract is not subject to mandatory notarization or certification. A written lease signed by both parties is fully valid and enforceable provided it meets the general validity conditions of the Civil Code 2015 (Article 117): lawful parties, voluntary agreement, lawful content and purpose. The lease’s term — 6 months, 2 years, 5 years — does not change this: duration is irrelevant to the notarization question.
What “not required” doesn’t mean
Notarization is optional but useful in specific cases: 1) high-value, long-term villa leases where extra evidentiary weight helps; 2) leases used in administrative files where an agency asks for notarized copies (provide them — it doesn’t make the lease itself “more valid”); 3) where a party cannot sign in person and authorization documents need authentication. What notarization does not do: cure an unlawful lease (e.g., the “landlord” has no right to lease), or override the contract’s own terms.
Don’t confuse with contracts that DO require notarization
House sale/purchase, gift, mortgage, and capital-contribution contracts involving residential property generally require notarization or certification — that’s where the confusion comes from. Lease sits in the exempt group. If anyone tells you a lease “must” be notarized, ask them to cite the provision — they won’t find one.
FAQs
1. My 5-year villa lease — surely that needs notarization?
No. Term length doesn’t trigger notarization for leases. Optional for evidentiary comfort, never mandatory.
2. We notarized anyway — any downside?
None legally — just cost and time. Keep the original; it doubles as strong evidence.
3. Oral lease — valid?
Technically a civil transaction can be oral, but for housing: always written. An oral lease is an evidentiary nightmare — deposit, term, rent all become disputes.
4. Lease signed abroad via scan — valid?
Yes, if genuine consent is provable. For high value, use e-signature or authorization paperwork.
5. Does the lease need the ward’s certification stamp?
No — no administrative certification is required for validity. The temporary-residence declaration is separate.
