Prevent forgery and tampering with verified contracts
Electronic contracts are legally recognized based on regulations
The validity of electronic contracts is specified by law and has the same legal effect as printed documents.
Civil Law (Principle of Non-formal Consensual Contracts)
Under Korean civil law, contracts are established solely through agreements between parties without requiring a specific form, following the principle of non-formal consensual contracts. In other words, regardless of the contract format, if the fact of agreement to the contract terms is proven, it is legally recognized.
Basic Act on Electronic Documents and Electronic Transactions
Article 4 (Validity of Electronic Documents) ① An electronic document shall not be denied legal effect solely because it is in electronic form. Article 4-2 (Written Requirements for Electronic Documents) An electronic document shall be regarded as a written document if it meets all of the following requirements. However, if special provisions exist in other laws or if its nature does not allow an electronic form, it shall not be considered as written. 1. The content of the electronic document must be readable. 2. The electronic document must be preserved in a form that allows it to be reproduced in the same manner as when it was created, converted, transmitted, received, or stored.
Electronic Signature Act
Article 3 (Validity of Electronic Signatures) ① An electronic signature shall not be denied validity as a signature, seal, or name stamp solely because it is in electronic form. ② If an electronic signature is selected as a method of signature, seal, or name stamp based on legal provisions or agreements between the parties, it shall have the same legal effect as a signature, seal, or name stamp.
