Service overview for this area
"Affidavit, Oath & Sworn Declaration for use in Spain" by NYC Legal & Notary (NPT) — 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 Spain, covering every category the receiving authorities recognize, including Non-lucrative visa · Digital Nomad visa · Padrón registration. For Spain, the recognition route is a single-step Apostille issued by the Department of Consular Affairs (MFA), in force in Thailand since 15 January 2026. Service starts at THB 2,000 per document set, with end-to-end turnaround of 2–3 business days depending on the consulate schedule. NPT manages the entire chain — notarization by a registered Thai attorney → certified translation (Translator Affidavit) → MFA → consular post → international courier to Spain via DHL or EMS — so clients never have to travel between government offices.
Why Thai documents bound for Spain must first pass a Thai Notary Public
Spain is one of the most frequent destinations for documents notarized at NPT. Any Thai-issued instrument used officially in Spain must travel through the "international document recognition chain" so that the receiving authority can verify that the record 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 consular post 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 Consular post of Spain 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 Spain, the paperworks we notarize most often are Non-lucrative visa · Digital Nomad visa · Padrón registration. Our team has processed more than one thousand documents per year destined for Spain 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 Spain
Based on NPT's internal caseload, the six document types most frequently notarized for Spain are: (1) BOJ.5 Shareholders List; (2) Certified Copy of House Registration (Tabien Baan); (3) Single Status Affidavit; (4) Distribution / Agency Agreement; (5) Patent Assignment Agreement; (6) Distribution / Agency Agreement.
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 Spain 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 Spain
Thailand acceded to the Hague Apostille Convention with effect from 15 January 2026, and Spain has been a member since 1978. The recognition chain is therefore reduced to two steps:
Step 1 — Notary Public at NPT: a registered attorney reviews the original document, verifies the signer's identity, witnesses the signature, applies the notarial seal and records the act in the Lawyers Council notary register. Time required: 30–60 minutes.
Step 2 — Document attestation at the Department of Consular Affairs (MFA), Chaeng Watthana: NPT runs this step on your behalf at no surcharge. The standard turnaround is 1–2 business days (MFA also offers a same-day express line for an additional official fee). The MFA attaches the Apostille certificate, and the record is immediately recognized in Spain — no diplomatic mission step is required.
Total wall time: 2–3 commercial days. Typical end-to-end cost: THB 3,000–5,000 per document set, depending on translation needs.
Real engagements NPT has handled for Spain
Case 1 — Heirs to an estate located in Spain need a notarized Power of Attorney authorizing a local attorney to administer the probate proceedings on their behalf. NPT prepared the documents in the format required by the receiving authority, coordinated the consulate and MFA queues, and delivered the legalized set within three business days.
Case 2 — Heirs to an estate located in Spain need a notarized Power of Attorney authorizing a local attorney to administer the probate proceedings on their behalf. NPT issued the underlying affidavit, prepared the certified translation with a Translator Affidavit in the format Spain requires, and delivered the package in time for the client's departure date.
Case 3 — A Thai family joining their spouse in Spain requires a notarized Parental Consent for Minor Travel and a translated marriage certificate accepted by Spain authorities. NPT's corporate team advised on board-resolution drafting, specimen-signature procedures and prepared the full corporate notarization bundle accepted by the registrar in Spain.
Case 4 — Heirs to an estate located in Spain need a notarized Power of Attorney authorizing a local attorney to administer the probate proceedings on their behalf. Real-time status updates were issued by LINE/WhatsApp at every milestone — notarization, MFA, consulate, dispatch — so the client never had to chase progress by phone.

Embassy and authority coordination in Spain
Apostille issuance in Thailand is centralized at the Department of Consular Affairs (Ministry of Foreign Affairs), 123 Chaeng Watthana Road, Thung Song Hong, Lak Si, Bangkok 10210 (Mon–Fri 08:30–15:30). Once the Legalization is affixed, the document is accepted directly in Spain — no diplomatic mission step required. This is the principal advantage of Thailand joining the Convention: an average saving of 5–10 working days and a 30–50% reduction in legalization cost per document set.
Six tips to get Affidavit, Oath & Sworn Declaration accepted in Spain on the first try
1) Provide a passport bio-page copy for every signer — the Spain consular post 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 consulate schedules slow down around Thai public holidays as well as Spain national holidays.
Frequently asked questions
What steps does a Thai notarized document need before it can be used in Spain?
Because Spain is a member of the Hague Apostille Convention — and Thailand's accession took effect on 15 January 2026 — the chain is now only two steps: (1) notarization by a Notarial Services Attorney registered with the Lawyers Council of Thailand, and (2) an Legalization certificate from the Department of Consular Affairs (MFA). The Apostille is recognized directly in Spain; no consular post step is required. Total turnaround: 2–3 business days.
What is the typical total cost for a notarized package destined for Spain?
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 the MFA Apostille fee is approximately THB 800 per document. End-to-end packages usually fall between THB 3,000 and THB 9,000 depending on volume and certified translation needs.
How long will the entire process take for Spain?
Notarization in 1 day, MFA Apostille in 1–2 business days — about 2–3 enterprise days total. An express MFA option can complete the Certificate authentication the next day for an additional fee.
Can your notary travel to my home or office to take the signature?
Yes. NPT 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 Spain 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 Spain 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 Spain?
English is typically the broadest-accepted target language. Some agencies in Spain may additionally require a translation into the local language — NPT's in-house language conversion desk advises based on the receiving authority.
