Notary Public for Affidavit of Authorized Signatory

Affidavit of Authorized Signatory · § signatory
Before you proceed
Prepare an authorized-signatory affidavit with company evidence. Check the required oath or affirmation; notarization does not appoint directors or create signing authority.
Turnaround: Estimated after document review; consular and embassy steps depend on those offices.
Document scope and limits of certification
Separate identity from authority. A passport identifies the individual; registry records, signing conditions and relevant resolutions support what that individual may do for the company. The statement should match that evidence.
Do not replace a recipient’s certificate wording with a generic stamp. An oath or affirmation differs from an acknowledgment. Confirm the act a Thai attorney can perform and the form the recipient will accept before the appointment.
What to prepare before an appointment
- Recipient’s affidavit and certificate wording
- Declarant’s identity document
- Company certificate, signing conditions and relevant resolution or delegation
Certification steps requested by the recipient
Obtain the recipient’s form and certificate wording → check identity and authority evidence → make the statement and sign before the required witness → translate or legalize if requested.
Typical use cases
- Supporting signing authority for a bank’s checklist
- Providing a declaration requested for a transaction
Common pitfalls
- An affidavit is not a substitute for required registry records or resolutions.
- Jurat and acknowledgment serve different purposes; follow the form and jurisdiction, not a blanket US rule.
- The declarant is responsible for the statement; notarization does not audit every business fact.

Frequently asked questions
- Does Thailand have notaries public?
- Thailand uses Notarial Services Attorneys registered with the Lawyers Council of Thailand for notarial acts within their permitted scope. Acceptance abroad depends on the recipient. Ask which certifier, wording and any additional authentication it requires; notarial certification is not the same as an Apostille.
- What documents can a Notarial Services Attorney certify?
- Commonly certified items include signatures on powers of attorney, affidavits and statutory declarations, certified true copies of passports and corporate documents, company resolutions and share transfer forms, sponsorship and consent letters, and the identity of a signatory for foreign banks, universities and courts. The attorney certifies the signing act or copy fidelity — not the truth of the content.
- Do I have to sign in person?
- Yes. The attorney must see the signatory in person together with the original passport or Thai ID before certifying a signature, which is the core safeguard of the service. Remote or scanned signatures cannot be certified. Mobile appointments at your office, condominium lobby or a nearby café are available if you cannot come to ours.
- How much does notarial certification cost and how fast is it?
- Attorney notarial certification starts at the current official rate per document, with the final price depending on the number of documents, signatories and whether the appointment is mobile or out of hours. The certification itself is completed during the appointment; only the subsequent MFA and embassy steps add working days.
