Determination of the time and place of dispatch and receipt of electronic messages is an important element of the operation of many rules of law, particularly the timing of formation of the contract. In this paper, I reviewed interpretation and application of time and place of dispatch and receipt of electronic records in electronic transactions under the UNCITRAL(United Nations Commission on International Trade Law) Model Law on Electronic Commerce, USA Uniform Electronic Transactions Act and Korea Electronic Transactions Act. Time of dispatch and time of receipt are effective when received. The sender has the burden to prove that the electronic record is sent successfully to the information process system of the recipient. Therefore, to safety electronic transactions, the sender needs to request a confirm notice for receipt to the recipient when the electronic record is sent like the provisions of UNCITRAL Model Law on Electronic Commerce and Korea Electronic Transactions Act. By requesting the above, the sender is able to take precautionary measures for damage according to the failure of dispatch and receipt of the electronic records.
