Service overview for this area
"Affidavit, Oath & Sworn Declaration for use in Sudan" by Thai Notary Law & Service (Thai Notary) — a Bangkok-based law firm whose attorneys are registered Notarial Services Attorneys with the Lawyers Council of Thailand. We notarize Thai-origin documents intended for official submission in Sudan, covering every category the receiving authorities recognize, including Work visa · Residence permit · Marriage registration · Oil contractor. For Sudan, the recognition route is a two-tier legalization chain at the MFA followed by the Consular post of Sudan in Bangkok (สถานทูตซูดาน, Sukhumvit Soi 39, Watthana). Engagement starts at THB 2,000 per document set, with end-to-end turnaround of 5–14 business days depending on the consulate schedule. Thai Notary public manages the entire chain — notarization by a registered Thai attorney → certified translation (Translator Affidavit) → MFA → embassy → international courier to Sudan via DHL or EMS — so clients never have to travel between government offices.
Why Thai documents bound for Sudan must first pass a Thai Notary Public
Sudan is one of the most frequent destinations for documents notarized at Thai Notary. Any Thai-issued instrument used officially in Sudan 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 consulate in Bangkok will only authenticate documents that already carry such an attorney's signature and seal.
Thai Licensed notary 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 Diplomatic mission of Sudan 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 Affidavit, Oath & Sworn Declaration use-case bound for Sudan, the paperworks we notarize most often are Work visa · Residence permit · Marriage registration · Oil contractor. Our team has processed more than one thousand documents per year destined for Sudan and is familiar with the exact format the receiving authorities expect, keeping the rejection rate below 0.5%.
Six Affidavit, Oath & Sworn Declaration document types most commonly sent to Sudan
Based on Thai Notary's internal caseload, the six document types most frequently notarized for Sudan are: (1) Patent Assignment Agreement; (2) Educational Credential Affidavit; (3) Affidavit of Income; (4) Single Status Affidavit; (5) Power of Attorney; (6) Single Status Affidavit.
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 public then attests.
Thai Notary maintains a library of over 50 sample documents previously accepted by Sudan 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 Sudan
Sudan 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 Thai Notary: 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: Thai Notary public'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 Sudan (สถานทูตซูดาน, Sukhumvit Soi 39, Watthana): Thai Notary presents the MFA-authenticated document at the diplomatic mission. Processing time is 14 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.

Embassy and authority coordination in Sudan

Thai Notary's runner team is familiar with each Bangkok diplomatic mission's protocols — walk-in versus appointment-only, fee schedules, accepted document formats — which materially reduces the chance of rejection on minor format issues.

Six tips to get Affidavit, Oath & Sworn Declaration accepted in Sudan on the first try
1) Provide a passport bio-page copy for every signer — the Sudan 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 — Thai Notary 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 diplomatic mission schedules slow down around Thai public holidays as well as Sudan national holidays.
Frequently asked questions
What steps does a Thai notarized document need before it can be used in Sudan?
Sudan is not yet a party to the Hague Apostille Convention, so the document must complete the full three-step legalization chain: (1) notarization by a registered Thai Notarial Services Attorney, (2) authentication by the Department of Consular Affairs (MFA, Chaeng Watthana), and (3) legalization at the Consular post of Sudan in Bangkok. Thai Notary handles all three steps end-to-end.
What is the typical total cost for a notarized package destined for Sudan?
Notary service starts at THB 1,500 per set, certified translation runs THB 500–1,200 per page depending on language, MFA authentication is THB 200 per document plus the official fee, and consulate legalization fees vary by mission (typically THB 800–3,000 per document). End-to-end packages usually fall between THB 3,000 and THB 9,000 depending on volume and official rendering needs.
How long will the entire process take for Sudan?
Notarization 1 day, MFA authentication 1–2 business days, then Sudan diplomatic mission legalization according to that mission's schedule (typically 3–10 commercial days). Total runway: 5–14 business days. Thai Notary runs the consulate queue on your behalf so you do not have to travel.
Can your notary travel to my home or office to take the signature?
Yes. Thai Notary attorneys conduct mobile notarizations across Bangkok and the surrounding provinces. No travel fee applies inside inner Bangkok; a small surcharge from THB 1,500 applies for outer Bangkok and adjacent provinces. We also accept original documents via EMS, Kerry or Grab, and we can ship completed packages to Sudan by DHL or EMS International.
Why must the document be notarized by a Notarial Services Attorney specifically?
Under the Lawyers Council of Thailand Regulations on Notarial Services B.E. 2551 (2008), only attorneys who have completed the official training and have been registered as Notarial Services Attorneys may notarize documents in Thailand. The MFA and Sudan diplomatic mission verify the attorney's signature against this register — documents notarized by an unregistered lawyer will be rejected at the MFA stage.
Does the document need to be translated before it is presented in Sudan?
English is typically the broadest-accepted target language. Some agencies in Sudan may additionally require a translation into the local language — Thai Notary's in-house official rendering desk advises based on the receiving authority.
