Why a Company Affidavit / DBD Cert issued in Bangkok needs MFA legalisation + embassy before Iran will accept it
A Company Affidavit / DBD Cert produced by a Thai authority — whether the Amphoe Mueang office in Bangkok, a Thai university, the Royal Thai Police, or a Bangkok commercial registrar — has no automatic extraterritorial effect. The receiving authority in Iran (immigration, university, court, civil registry, bank, or Embassy of the Islamic Republic of Iran counterpart) needs cryptographic-grade assurance that the Thai signature, seal and paper are genuine. That assurance is provided by the Thai Ministry of Foreign Affairs' Department of Consular Affairs at Chaeng Watthana through a full legalisation chain authorised under the bilateral consular convention with Iran.
For clients in Bangkok Province, NAATI Thailand removes every kilometre and queue: originals are couriered to our Lat Phrao office, drafted by a Sworn Persian Translator into Persian (Farsi) using the format Iran ministries prefer, notarised by a Lawyers Council attorney, then walked through MFA Chaeng Watthana — express track available — and forwarded to the Embassy of the Islamic Republic of Iran, Bangkok for the second legalisation layer. The entire pipeline completes in 18-25 วันทำการ including return courier to Bangkok or direct shipment to the receiving authority in Iran.

Across our 2024–2026 case file we have routed Company Affidavit / DBD Cert from Bangkok for use in Iranacross these scenarios: Marriage RegistrationFamily VisaStudent / Religious Studies. Each scenario carries slightly different formatting expectations (page headers, signature placement, translation footer), which is why working with a translator who is registered for Iran authorities — not a generic agency — matters.
What clients in Bangkok must prepare
- Fresh original Company Affidavit / DBD Cert with raised seal (re-issued within the last 6 months for civil-registry items).
- Copy of the signatory's national ID or passport (clear scan acceptable).
- If the document originates from the Amphoe Mueang office in Bangkok, request a new "certified copy with raised seal" — photocopies are rejected.

Common mistakes when sending from Bangkok to Iran
- แปล English อย่างเดียว — Iran ต้อง Persian
- ลืม MOFA Tehran
- Skipping the Embassy of the Islamic Republic of Iran, Bangkok step — the destination authority will reject MFA-only files.
- Translating after MFA instead of before — the MFA stamp must cover the translation footer, not the source-language original alone.
- Using a freelance translator without an MoJ / Sworn registration — Iran authorities verify against public registries.
