What Does “Certify Signature” Mean?

To certify a signature means that a qualified legal professional verifies:

• The identity of the person signing the document

• That the person signs voluntarily

• That the signature is genuine

• That the document was signed in the presence of the certifying officer

In Thailand, this service is performed by a lawyer who has completed Notarial Services Attorney training under the Lawyers Council of Thailand.

This process is commonly referred to as:

• Signature Certification

• Signature Notarization

• Notarial Certificate

• Notary Public Service (Thailand)

When Do You Need Signature Certification?

You may need to certify your signature in the following situations:

1. Power of Attorney (POA)

• Appointing someone to handle property transactions

• Managing bank accounts

• Company registration matters

• Visa or immigration filings

2. Company & Corporate Documents

• Board resolutions

• Share transfer agreements

• Director declarations

• Business contracts

3. Bank & Financial Documents

• Overseas bank account opening

• Investment agreements

• Loan documents

4. International Use

If the document will be used abroad, certification may be required before legalization by the Department of Consular Affairs and submission to a foreign embassy.

Step-by-Step Process to Certify Signature

Step 1: Prepare the Document

Bring the unsigned document (or inform us if already signed).

Step 2: Identity Verification

Present your passport or Thai ID card.

Step 3: Sign in Front of the Lawyer

The signature must be made in the presence of the certifying lawyer.

Step 4: Notarial Certificate Issued

The lawyer attaches a Notarial Certificate and official seal.

What Is Included in a Notarial Certificate?

A proper certification typically includes:

• Statement confirming identity verification

• Confirmation that the signature was made in the lawyer’s presence

• Date and location

• Lawyer’s signature

• Official Notarial seal

This ensures the document can be relied upon by banks, government agencies, and foreign authorities.

Can Thailand Issue “Notary Public” Certification?

Thailand does not have a traditional Notary Public system like the US or UK. Instead, certification is performed by lawyers authorized as Notarial Services Attorneys by the Lawyers Council of Thailand.

Therefore:
✔ Signature certification in Thailand = Notarial Service by qualified lawyer
✔ Accepted for most international transactions
✔ Can proceed to legalization if required

Do You Need Legalization After Signature Certification?

If your document will be used overseas, you may need additional steps:

1. Signature Certification by Notarial Services Attorney

2. Legalization by the Department of Consular Affairs

3. Authentication by the relevant Embassy

We can advise you on the correct procedure depending on the destination country.

Why Proper Certification Matters

Improper certification can result in:

• Bank rejection

• Embassy refusal

• Immigration delay

• Business contract invalidity

• Loss of legal protection

Having your signature certified correctly ensures:

• Legal reliability

• International acceptance

• Professional documentation standard

• Reduced legal risk
