In principle, the business transferor must provide the above information in writing (eg, written document, email, fax, phone, text message or any other equiva - lent method). However, if the business transferor is unable to provide such information in writing without negligence, the business transferor must publish this information on a website for at least 30 days. If there is a justifiable reason for not being able to publish the above information on a website, the business trans- feror must: • publish the above information in an easily visible location within the business transferor’s place of business for at least 30 days; or • publish it in a daily newspaper that is mainly dis - tributed in the city, province or region where the business transferor’s place of business is located. The business transferee has the same notification obligation as the business transferor. However, if the notification has been provided by the business trans - feror, the business transferee is not required to pro - vide one. Meanwhile, a business transferee that has received personal information as part of a business transfer or merger may use the personal information or provide it to a third party only for the original purpose for which it received the information.

Third-Party Transfers Separate from such regulation regarding overseas transfers, transferring personal information to a third party outside Korea for the purpose of either provid - ing personal information to a third party or delegating the processing of personal information also consti - tutes third-party provision or delegation of processing of personal information under the PIPA, respectively – these are subject to the relevant provisions of the PIPA in addition to the above-mentioned regulation on overseas transfer. Third-party provision occurs where a data controller provides personal information to a third-party recipient for the purpose and benefit of the third-party recipient. Delegation occurs where a third-party entity processes personal information that it receives from the data controller for the purpose and benefit of the data controller.
