Electronic Signatures Act Article 5

The requirement for the use of a document and a signature is satisfied by using an electronic record and an electronic signature.Where a law or regulation requires that information be provided in writing, if the content of the information can be presented in its integrity and remains accessible for subsequent reference, the requirement is satisfied by providing an electronic record.Where a law or regulation requires a signature or seal, the requirement is satisfied by using an electronic signature.If the use of a document or a signature under the preceding three paragraphs involves another party, unless the counterparty has agreed to the use of electronic form, counterparty shall be provided with the opportunity of objection thereto within a reasonable period and in a reasonable manner, and counterparty shall be informed that if no object is raised, it shall be presumed to have agreed to the use of electronic form.The above said counterparty may indicate the discontinuance of the use of electronic form at any time; provided, however, the effect of legal acts conducted in electronic form before its indication of discontinuance shall not be affected.
