Legalising a Thai Thai ID Card for Portugal
If you are relocating to, studying in, marrying in, or doing business with Portugal, your Thai Thai ID Card will only be accepted once it carries both the Thai MFA legalization stamp and the Portugal embassy authentication. We prepare the certified translation, secure the consular stamp in Chaeng Watthana, and submit the file to the Portugal mission at ถนนสาทรใต้ on your behalf.
Why the legalization chain is required
Legalization is a chain of trust, not a formality. When a Portugal officer sees the embassy stamp on your Thai ID Card, 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 Portugal authority accepts the document without follow-up questions.
Certified translation requirements
Translation is not optional cosmetic work — it is part of the legal instrument. For Portugal, the Thai ID Card translation must mirror every seal, marginal note and signature block of the Thai original. Our translators reproduce the full layout, then attach a signed certificate of accuracy that the Legalization Division will authenticate.
Transparent, itemised pricing
Budget realistically: the Embassy of Portugal charges 20-100 EUR for authenticating a Thai ID Card, 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 Thai ID Card 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 Portugal embassy stage, on top of 2–3 business days at the Thai MFA and 1–3 days for certified translation. Realistically a single Thai ID Card 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 Thai ID Card is used for
A legalised Thai ID Card is commonly required by Portugal 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 Portugal mission include Apostille, Tradução Certificada.
Common mistakes we help you avoid
Rejections usually come from small, avoidable errors: an expired Thai ID Card, a translation that omits an official annotation, a name that reads differently from the passport, or a document submitted to the Portugal embassy out of sequence. We verify document freshness, translation completeness and stamp order before anything is lodged.
