Why Thai documents bound for Iran must first pass a Thai Notary Public
Iran is one of the most frequent destinations for documents notarized at NPT. Any Thai-issued instrument used officially in Iran must travel through the "international document recognition chain" so that the receiving authority can verify that the paperwork was executed by a person or entity with genuine authority. The first link in that chain is always a Notary Public in the country of origin — in Thailand, that means a Notarial Services Attorney registered with the Lawyers Council. The MFA and every foreign diplomatic mission in Bangkok will only authenticate documents that already carry such an attorney's signature and seal.
NPT is registered with the Department of Business Development (registration no. 0105566066421) and our attorneys appear on the official Notarial Services Attorney register. The MFA and the Consulate of Iran can verify our signatures against that register at any time, which is why documents leaving our office complete the chain reliably — we do not see rejections caused by an unrecognized notary.
For the Certified Translation by Notarial officer Public use-case bound for Iran, the paperworks we notarize most often are Work visa · Family reunification · Marriage registration · Property registration. Our team has processed more than one thousand documents per year destined for Iran and is familiar with the exact format the receiving authorities expect, keeping the rejection rate below 0.5%.
Six Certified Translation by Notary Public document types most commonly sent to Iran
Based on NPT's internal caseload, the six document types most frequently notarized for Iran are: (1) Educational Credential Affidavit; (2) Certified True Copy of Passport; (3) Patent Assignment Agreement; (4) BOJ.5 Shareholders List; (5) Specimen Signature of Directors; (6) BOJ.5 Shareholders List.
Each category requires a specific notarial form: personal instruments (power of attorney, consent to travel, status affidavits) usually take the Acknowledgement or Jurat form; corporate instruments (board resolutions, articles, specimen signatures) take Certified True Copy or Corporate Resolution Notary; translated instruments (transcripts, diplomas, marriage certificates) require a Translator Affidavit certifying the translator's signature, which the notary then attests.
NPT maintains a library of over 50 sample documents previously accepted by Iran authorities. Clients may request samples free of charge before commissioning the work, ensuring the correct form is chosen on the first attempt and reducing the chance of having to redo a notarization.
Step-by-step legalization workflow for Iran
Iran is not yet a party to the Hague Apostille Convention (non-Hague jurisdiction), so the full three-step legalization chain remains in force:
Step 1 — Notary Public at NPT: a Notarial Services Attorney executes the notarization either at our Lat Phrao 95 office or at the client's location. Time required: 30–60 minutes.
Step 2 — MFA authentication, Department of Consular Affairs, Chaeng Watthana: NPT's runner team files the document at the MFA (1-day express or 2-day standard). The MFA verifies the attorney's signature against its register and stamps its own authentication.
Step 3 — Consulate of Iran (สถานทูตอิหร่าน, Soi Pridi Banomyong, Watthana): NPT presents the MFA-authenticated document at the consular post. Processing time is 7–10 business days; fees follow each mission's published schedule. Some embassies require advance appointments, others accept walk-ins — our team handles whichever protocol applies.
Total wall time: 5–14 commercial days, depending on the embassy's calendar. Typical end-to-end cost: THB 5,000–9,000 per record set.
Real engagements NPT has handled for Iran
Case 1 — A foreign national marrying a Thai citizen plans to register the marriage in Iran; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized. NPT prepared the documents in the format required by the receiving authority, coordinated the consulate and MFA queues, and delivered the legalized set within seven business days.
Case 2 — A foreign national marrying a Thai citizen plans to register the marriage in Iran; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized. NPT issued the underlying affidavit, prepared the certified translation with a Translator Affidavit in the format Iran requires, and delivered the package in time for the client's departure date.
Case 3 — An expatriate professional relocating to Iran needs a notarized Translator Affidavit plus certified copies of educational credentials before the employer files for the work permit. NPT's corporate team advised on board-resolution drafting, specimen-signature procedures and prepared the full corporate notarization bundle accepted by the registrar in Iran.
Case 4 — A foreign national marrying a Thai citizen plans to register the marriage in Iran; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized.

Embassy and authority coordination in Iran
Documents already authenticated by the MFA must be presented at the สถานทูตอิหร่าน, located in Soi Pridi Banomyong, Watthana, Bangkok. The consulate's standard processing time is 7–10 business days. NPT's runner team is familiar with each Bangkok consulate's protocols — walk-in versus appointment-only, fee schedules, accepted document formats — which materially reduces the chance of rejection on minor format issues.
Clients outside Bangkok do not need to travel: send the originals to our Lat Phrao 95 office by EMS or Kerry and NPT executes the notarization, MFA filing, embassy legalization and final dispatch — either back to the client or onward to Iran by DHL International.
Six tips to get Certified Translation by Notary Public accepted in Iran on the first try
1) Provide a passport bio-page copy for every signer — the Iran diplomatic mission uses it to verify name consistency across the document set.
2) State the intended purpose clearly (e.g. "for use in a work-permit application", "for submission to the receiving government agency") — the appropriate notarial form depends on purpose, even for the same underlying document.
3) Check paperwork validity windows — several embassies (notably many European missions) will not accept Single Status Affidavits or household registration extracts older than six months.
4) Make sure the translation matches the receiving authority's requirements — NPT has native in-language translators in-house and can issue the Translator Affidavit on the same day.
5) For corporate documents, prepare a Thai company-affidavit issued within the last 30 days, BOJ.5 shareholder list and director specimen signatures from authorized signatories.
6) Build a 7–14 day buffer before any hard deadline — MFA and consular post schedules slow down around Thai public holidays as well as Iran national holidays.
