Submitting a change-of-surname certificate to Denmark — how must it be translated and certified?

The issue to settle here is “Submitting a change-of-surname certificate to Denmark”, so the answer below starts with what this case actually needs before setting out the general rules. After filing, follow up on the cycle the office states rather than waiting past the deadline. If an entry has been amended, request the certificate of amendment and file it alongside. Settlement agreements must be translated clause by clause with nothing dropped. Some birth and death certificates carry two identity numbers; translate both. Exhibits must be numbered to match the numbering used in the complaint. Documents with a short validity window should be produced as close to the filing date as possible. When several certification layers are required, start with the slowest one. Record the reference number of each certification layer; it is the fastest way to trace status. Attach a document index to the bundle so nothing is lost during review. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. The common failure in this group of cases is a translation that does not match the certification type required. 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. The specifics here are document type: Surnamechange; destination: Dk, and those decide which translation and certification level applies.

A Thai civil registration document for overseas use is normally translated into the language the destination requires, then legalised by the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, and where required further legalised by the destination country's embassy or consulate. Most receiving authorities want a registrar-certified copy of the register rather than a photocopy made by the holder, because the certified copy carries the registrar's signature and seal that the Ministry of Foreign Affairs can verify; obtain a freshly issued certified copy before starting the translation and legalisation steps. Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so consular legalisation through the Ministry of Foreign Affairs and the relevant embassy remains the working route; confirm the current requirement with the receiving authority before filing. Cost and lead time depend on the number of documents, the language pair and the certification steps the receiving authority requires, so every file is quoted before work starts.
