How do I apostille a Thai Company Affidavit / Certificate for Portugal?
NAATI Thailand handles the full Thai-Apostille workflow for the Company Affidavit / Certificate destined for Portugal 🇵🇹: (1) certified translation by a registered translator into โปรตุเกส (European), (2) Notary Public certification of the translator's signature, (3) MFA legalization at the Department of Consular Affairs (Chaeng Watthana). Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, with entry into force for Thailand on 28 February 2027, until then, embassy legalisation may still be required for Portugal — confirm the current chain with the receiving authority. Package quoted on request, turnaround 7 วันทำการ. Scan-first via LINE @NAATI from anywhere in Thailand or overseas.

Company Affidavit / Certificate Apostille for Portugal — end-to-end workflow
NAATI Thailand operates a dedicated Apostille desk for the Thai Company Affidavit / Certificate (issued by Department of Business Development), with end-to-end delivery to Portugal 🇵🇹. We translate, notarise and walk the file through the Ministry of Foreign Affairs at Chaeng Watthana under one job number — the workflow most consulates, universities and immigration officers in Portugal expect to see.
Why Apostille (not Embassy Legalisation) for Portugal — Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, with entry into force for Thailand on 28 February 2027. Portugal is a Hague member, which means a single Thai MFA legalization stamp replaces the previous Embassy-of-Portugal legalisation step. The chain is shorter, the cost is lower, and the apostille is internationally verifiable from a register number.
Certified translation requirement — Receiving authorities in Portugal require the Company Affidavit / Certificate in โปรตุเกส (European). The translation must be performed by a Notary + Tradutor Certificado + Apostille. We allocate the job to a senior translator with at least 8 years of certified-translation experience; the file is bilingually proofread by a second linguist before notarisation.
Document preparation before MFA — หนังสือรับรองตัวจริง (อายุไม่เกิน 30 วัน) + แปล + Notary. ต้องขอใหม่ทุกครั้ง — อายุ 30 วันเท่านั้น. We confirm the romanised spelling of your name against your passport bio-page in writing before drafting, so the apostilled translation matches every other Portugal-side filing (visa, civil registry, university, professional council).

Why receiving authorities accept our package — Each apostilled bundle leaves our chambers with: original Thai document (or certified true copy), certified โปรตุเกส (European) translation on letterhead with translator's signature and stamp, Notary Public seal certifying the translator's signature, MFA legalization on the translation (and original where required), and a numbered certificate of accuracy. This is the exact stack Portugal consulates, civil registries and the receiving authority routinely accept.
