eSignature legality summary
A written signature is not required for a valid contract — parties can agree verbally, electronically (where reproducible in physical form and integrity is demonstrable), or on paper (Macau Civil Code arts. 211 ff. and 362). Electronic records are admissible under Civil Code arts. 355 and 362 and Civil Procedure Code art. 450 ff.
Types of permitted electronic signature
A standard electronic signature is generally appropriate for ordinary commercial use; admissibility depends on the record being reproducible in physical form with demonstrable integrity.
Documents that may be signed electronically
Suitable for HR documents, commercial agreements (NDAs, purchase orders, procurement, sales, distribution, service), most consumer agreements (excluding consumer loan agreements), and software licenses.
