Professional Notarial Services Attorney in Bangkok, Thailand

NS International Law provides affidavit notarization, sworn statement certification, statutory declaration assistance, and signature witnessing services for individuals, expatriates, foreign nationals, and businesses in Thailand.

If you need to sign an affidavit for use overseas, our Notarial Services Attorney can assist with verifying your identity, witnessing your signature, and preparing the appropriate notarial certification, subject to the requirements of the receiving authority.

What Is a Notarized Affidavit?

An affidavit is a written statement of facts that a person confirms to be true under oath or affirmation. The person making the statement is commonly referred to as the deponent or affiant.

Affidavits may be required for legal proceedings, immigration applications, family matters, international transactions, business affairs, and other administrative purposes.

A notarized affidavit generally involves a qualified professional verifying the identity of the person signing the document, administering an oath or affirmation where appropriate, and recording the execution of the affidavit.

In Thailand, notarial services are provided by lawyers registered as Notarial Services Attorneys with the Lawyers Council of Thailand. A Thai Notarial Services Attorney is not necessarily equivalent to a Notary Public in every foreign legal system. The receiving authority should confirm whether this form of certification is acceptable.

How to Notarize an Affidavit in Thailand

Documents Required for Affidavit Notarization

Before your appointment, please prepare the following documents:

• Original passport or valid Thai identification card.

• Draft affidavit or statutory declaration.

• Documents supporting the statements made in the affidavit, if applicable.

• Instructions or prescribed forms from the receiving authority.

• Information about the country where the affidavit will be submitted.

We recommend sending a scanned copy of your affidavit in advance so that the appropriate procedure can be reviewed before your visit.

Affidavit Notarization for Use Overseas

A notarized affidavit issued in Thailand may be intended for use in countries such as the United States, the United Kingdom, Australia, Canada, Singapore, or other foreign jurisdictions.

However, document acceptance requirements differ between countries and organizations. Some authorities accept certification by a Thai Notarial Services Attorney, while others require additional legalization, a particular form of oath, or execution before a consular officer or another authorized professional.

The purpose of notarization is generally to certify the relevant notarial act, such as identity verification, signature witnessing, or administration of an oath. It does not automatically establish the truth of every factual statement contained in the affidavit.

Clients should verify the receiving authority's requirements before arranging notarization.

Affidavit vs. Statutory Declaration

An affidavit is typically a written statement made under oath or affirmation. A statutory declaration is a formal declaration made under the requirements of a particular statute or legal procedure.

Although both documents may contain statements of fact, they are not always interchangeable.

For example, a foreign government agency may require a statutory declaration in a prescribed format rather than a general affidavit. Using the incorrect form can result in delays or rejection.

Our attorney can review the instructions provided by the receiving organization and advise on the appropriate notarial assistance available in Thailand.
