Acknowledgment vs Jurat — choosing the right notarial certificate
Foreign embassies and registrars expect a specific notarial certificate to follow each signature, and choosing the wrong one is the most common reason documents are rejected after a 7-day chain. An Acknowledgment certificate ('On this day personally appeared before me [name], known to me [or proved by identification] to be the person whose name is subscribed to the within instrument, and acknowledged that he/she executed the same for the purposes therein contained') is used when the signer is confirming the signature already on the document — typical for property deeds, contracts, corporate resolutions and POAs. A Jurat ('Sworn and subscribed before me on this day') is used when the signer is swearing the contents are true and signs while in the lawyer's presence — typical for affidavits, statutory declarations and sworn translations. US County Recorders reject acknowledgments used in place of jurats and vice versa. German Standesämter require a Jurat for marriage-related declarations. Italian consulates reject signatures with no separate certificate at all. Our drafting team selects the certificate based on the destination authority's known requirements rather than the client's preference.
The 4-step in-office workflow
- Identity verification — the signer presents the original unexpired passport (not a copy, not a digital photo); the attorney records passport number, date of issue, expiry and nationality in the Notarial Register, and photocopies the photo page for the file.
- Capacity check — the attorney confirms the signer understands what is being signed (English or Thai conversation), is acting voluntarily and is not under visible distress or intoxication; for elderly or hospitalized signers we may require a brief medical fitness note.
- Signature in the attorney's presence — the signer signs each page with black ballpoint or fineliner, while the attorney watches; pre-signed documents are NOT acceptable for a Jurat and require an Acknowledgment certificate instead.
- Certificate, seal and register entry — the attorney completes the chosen certificate (Acknowledgment or Jurat), affixes the embossed notarial seal, signs with full name and registration number, and enters the act in the Notarial Register with a unique sequential number that downstream verifications can cross-check.
What we notarize most often — by document type
Our office processes about 380 signature notarizations per month. The largest clusters are: (1) US-IRS Form W-9 and W-8BEN signatures for Thai-resident US citizens and US-source-income foreigners — Jurat preferred, IRS accepts the Thai notarial certificate without further legalization for tax purposes; (2) UK and Australian property-deed signatures from overseas-resident Thai citizens transferring inherited property in those countries — Acknowledgment with full apostille chain; (3) German and Austrian Vollmacht (Power of Attorney) for property and inheritance matters — Acknowledgment with the German-language certificate appended; (4) corporate signature pages for cross-border M&A — Acknowledgment for each signing director; (5) sworn translation certifications by registered translators — Jurat with the translator as affiant. We maintain certificate templates in English, German, French, Italian, Spanish, Japanese, Korean and Mandarin so the foreign authority does not need to translate the certificate itself.
Why online notarization (RON) is NOT yet legal in Thailand
Several US, Singapore and Hong Kong startups offer Remote Online Notarization (RON) targeting Thailand-based expats. As of 2026, RON performed by a foreign notary is NOT recognized by Thai authorities or by foreign embassies in Bangkok for documents intended for use in Thailand. The Lawyers Council of Thailand's 2008 Notarial Regulation explicitly requires in-person identification, and the Department of Consular Affairs at the Thai MFA will not legalize remotely notarized signatures. The US Department of State has clarified (consular bulletin, 2024) that RON notarizations performed by Virginia, Florida or Texas notaries are accepted for US-internal use but cannot be authenticated by US embassies abroad for foreign use. The practical implication: if your document needs to be used in Thailand, a Bangkok-based Notarial Services Attorney is the only legally safe path. If it needs to be used in the US, you may use US RON for purely domestic US matters, but our Bangkok service is still required when the document touches any Thai institution.
