Is electronic signature legal in Hong Kong?
Yes, with some exceptions. Hong Kong's Electronic Transactions Ordinance (Cap. 553) lets electronic signatures meet legal signature requirements in private transactions, while dealings with government need a digital signature backed by a recognized certificate. Wills, trusts, powers of attorney, land documents, instruments that must be stamped (such as tenancy agreements), oaths, affidavits and negotiable instruments are excluded.

E-signatures in Hong Kong: frequently asked questions
Can tenancy agreements be e-signed in Hong Kong?
Generally no. Tenancy agreements must be stamped under the Stamp Duty Ordinance, and instruments that must be stamped are excluded from the Electronic Transactions Ordinance, so they should be signed in wet ink. The Estate Agents Authority has warned that e-signed tenancy agreements may not be accepted for stamping.
Can property sale documents be signed electronically in Hong Kong?
Assignments, mortgages and other documents affecting land are excluded from the Ordinance, so they generally still need wet-ink execution.
Do I need a digital certificate to sign with government in Hong Kong?
Yes. Where a government entity is a party and a law requires a signature, a digital signature supported by a recognized certificate is required.
