Legalising a Thai Affidavit for Luxembourg
If you are relocating to, studying in, marrying in, or doing business with Luxembourg, your Thai Affidavit will only be accepted once it carries both the Thai MFA legalization stamp and the Luxembourg embassy authentication. We prepare the certified translation, secure the consular stamp in Chaeng Watthana, and submit the file to the Luxembourg mission at ถนนสาทรใต้ on your behalf.
Why the legalization chain is required
Legalization is a chain of trust, not a formality. When a Luxembourg officer sees the embassy stamp on your Affidavit, they are trusting the embassy, which trusted the Thai MFA, which trusted the issuing office. NYC Legal builds this chain in the correct order so the final Luxembourg authority accepts the document without follow-up questions.
Certified translation requirements
Most Luxembourg authorities require the Thai Affidavit to be accompanied by a certified translation into a language the mission accepts — typically English, or the official language of Luxembourg. The translation must be faithful, complete, and produced by a translator whose signature the Thai MFA can verify. We use MFA-recognised translators so the translation itself can be legalised alongside the original.
Transparent, itemised pricing
Budget realistically: the Embassy of Luxembourg charges 30-150 EUR for authenticating a Affidavit, the Thai MFA charges roughly THB 200–400 per document (express ~THB 800), certified translation runs about THB 800–1,500 per page, and the NYC Legal all-inclusive service fee is สอบถามเจ้าหน้าที่. A typical single Affidavit therefore lands in the THB 6,000–12,000 range once every counter is paid.
Realistic timelines you can plan around
Plan for 10-21 วัน at the Luxembourg embassy stage, on top of 2–3 business days at the Thai MFA and 1–3 days for certified translation. Realistically a single Affidavit takes 7–21 business days end to end. If you have a visa interview or filing deadline, tell us first — express MFA and priority embassy handling can compress this materially where the mission allows it.
What a legalised Affidavit is used for
A legalised Affidavit is commonly required by Luxembourg for immigration and visa applications, marriage registration, family reunification, university admission, employment and work authorisation, pension and social-security claims, property or inheritance matters, and company registration. The most requested documents at the Luxembourg mission include Apostille, Sworn Translation.
Common mistakes we help you avoid
Rejections usually come from small, avoidable errors: an expired Affidavit, a translation that omits an official annotation, a name that reads differently from the passport, or a document submitted to the Luxembourg embassy out of sequence. We verify document freshness, translation completeness and stamp order before anything is lodged.
Why work with NYC Legal
Doing this yourself means multiple trips across Bangkok, queueing at the MFA and the Luxembourg mission, and risking a wasted day if any detail is off. We consolidate the entire Affidavit legalization into one managed service, submit at ถนนสาทรใต้ on your behalf, and return the document ready to file — in Thailand or shipped internationally.
