IP due diligence before investment or M&A in South Korea — what translation and certification is expected?

The scope of this answer is “IP due diligence before investment or M&A in South Korea”, so it flags what usually causes documents like this to be rejected before summarising the general practice. The terms that frame this page are diligence · before · investment · South. The specifics here are purpose: Duediligence; destination: Kr, and those decide which translation and certification level applies. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. What changes the timeline most here is whether the source documents are complete on day one. If the receiving body confirmed its requirements by email, keep that message with the file. Note who signed each certification and on what date for later reference. Public holidays and embassy closures move certification queues more than most people expect. Documents with a short validity window should be produced as close to the filing date as possible. The next step is confirming the filing channel and the copy or file format required. Thai intellectual-property documents used abroad follow this order: a complete translation, signature certification by a notarial services attorney where the receiver requires it, certification by the Legalisation Division of the Department of Consular Affairs, Ministry of Foreign Affairs, then the destination embassy or consulate where required. Confirm the order with the receiving party first — skipping one step means starting again. Thailand acceded to the Madrid Protocol, in force for Thailand since 2017. An applicant may use a Thai application or registration as the basis for an international application filed through DIP as office of origin; WIPO records it and forwards it to the designated members. Examination and refusal remain with each designated office, so goods and services wording must be translated faithfully and consistently with the Nice classification. ILC handles documents only — translation, certified translation, arranging notarial-attorney certification and running legalisation at the Department of Consular Affairs and embassies. It is not a registered IP agent, not a law firm, does not file applications, does not give similarity or novelty opinions and guarantees no decision by DIP, WIPO or IP Australia. Cost and lead time depend on page count, target language, how technical the text is and the certification steps required, so every file is quoted before work starts.
