Notarization in Thailand is performed by Notarial Services Attorneys registered with the Lawyers Council of Thailand. Documents are then typically legalized at the MFA Department of Legalisation before embassy submission.

Witnessing of Contracts and Documents
Notary Public attorneys sign as neutral, highly credible witnesses — confirming the validity of contracts and legal acts.
Licensed Notarial Services Attorneys · Lawyers Council of Thailand
Our Team of 6 Licensed Notary Public Attorneys
Witnessing of Contracts and Documents is the act in which a Notary Public attorney signs a legal document as a ‘witness’ — a neutral third party with professional credibility, licensed by the Lawyers Council of Thailand. Unlike informal witnesses (friends or relatives), whose impartiality may be questioned in court or by foreign authorities, an attorney-witness reduces the risk of rejection and strengthens the evidentiary weight of the document if litigation arises.
Starting fee: THB 1,500/set — Provided by Thai Notary Law & Service Co., Ltd., DBD Reg. 0405565001923, Thailand.

Why use an attorney-witness instead of a friend or relative?
In court and before foreign authorities, an attorney-witness raises a document's credibility because (1) the attorney is a disinterested third party, (2) the attorney's license can be verified with the Lawyers Council of Thailand, (3) the attorney has a professional duty to verify the parties' identities and voluntariness, and (4) the witnessing event is logged in the Notarial Register, which can be cited in court.
Abroad, bodies like Companies House (UK), state Notary Publics (US), Justices of the Peace (Australia), and 公証役場 (Japan) routinely scrutinize a witness's identity and standing. Using a Notary Public attorney registered with the Lawyers Council of Thailand makes the destination authority's verification quick and smooth.
Our witnessing process
Step 1: Send the draft contract or document for pre-review. The attorney checks for void clauses, missing legal elements, and recommends wording improvements.
Step 2: Book the signing — at our office, your workplace, a mall, hotel, or home — whichever you prefer.
Step 3: On signing day, the attorney verifies each party's ID, confirms voluntariness, and ensures all parties understand the content.
Step 4: Each party signs in front of the attorney; the attorney then signs as witness, applies the Notary seal, logs the act, and issues a witnessing certificate.
Step 5 (optional): MFA legalization and destination-embassy attestation.
Case examples — how attorney-witnessing closed real deals
A THB 45M Bangkok condo sale between a Thai and foreign buyer — the seller wanted assurance that the transfer documents could not be challenged later. Our team witnessed the signing, certified copies of every document, and archived the file for 15 years.
A Thai-German joint venture — documents needed both Thai and German attorney-witnesses; we coordinated with the German Notar and witnessed on the Thai side, with both parties signing in a video conference attended by both attorneys.
A foreign national's will in Chiang Mai — to be effective in Australia, our attorney witnessed alongside an English-language interpreter, then MFA-legalized and shipped to Australia.

FAQ
Frequently asked questions
Is a Thai Notary Public different from a foreign Notary Public?
In Thailand, the Notary Public role is performed by ‘Notarial Services Attorneys’ licensed by the Lawyers Council of Thailand. Their certifications are valid abroad once further attested by the MFA Department of Consular Affairs and the destination embassy.
How long does the process take?
Typically 30–60 minutes per document set when booked in advance. MFA legalization adds 1–3 working days.
Can the notarized document be used abroad immediately?
Most overseas use requires three steps: (1) Notary by attorney (2) MFA legalization (3) Destination embassy attestation. We handle all three.
What is the starting fee, and are there additional costs?
Notary by attorney starts at THB 1,500 per document set. MFA legalization adds THB 200–800 government fee and THB 2,500–5,000 service fee per applicant for filing.
How does an attorney-witness differ from a layperson witness in court?
An attorney-witness carries greater evidentiary weight because they have a professional duty to verify identity and voluntariness, and the witnessing event is recorded in an auditable Notarial Register — both of which courts and foreign authorities trust more than a layperson witness.
Can witnessing be done via international video conference?
Where the destination jurisdiction permits, our attorney can witness via video conference jointly with a Notary in the other country — for example, certain US states allow Remote Online Notarization (RON). We confirm feasibility and prepare the destination-compatible format in every engagement.
Contract witnessing — attorney as independent third party verifies parties' identities, voluntariness of signing and retains a copy as evidence. For real estate, partnership, loan, marriage and prenuptial contracts. THB 2,000/contract, same day.

Service-specific FAQ
How is this different from Signature Notarization?
Signature Notarization certifies the signature only; Witness of Contracts covers the entire signing process — ID check on all parties, comprehension confirmation and 10-year archival for court testimony.
Can attorney witness at home/hotel?
Yes — on-site across Bangkok metro at THB 1,500 travel; upcountry per distance + travel.
Do you also draft the contract?
Witnessing excludes drafting (must remain independent third party); we offer separate drafting from THB 3,500 by a different attorney.
Why keep a copy?
For future disputes — Notary-archived copy is primary evidence in court under Civil Procedure Code §94.
Will the attorney testify in court?
Yes — the witnessing attorney can be subpoenaed; THB 8,000/day in Thai courts.

Supplemental Q&A from the 2026 SEO brief (this service)
What do I need for Power-of-Attorney (POA) notarization?
Bring (1) an UNSIGNED draft POA — you must sign in front of the attorney; (2) original passport or Thai ID; (3) attorney-in-fact details; (4) referenced supporting documents (land title, company affidavit). English POAs need a Thai translation if used in Thailand.
Does a foreigner's Will in Thailand need Notary certification?
A Will executed in Thailand under Civil Code §§1655-1672 needs only two witnesses — Notary is not required. But if the Will must be used abroad (e.g. to administer estate in the home country), we recommend Notary + MFA + embassy legalization for smoother acceptance.
How is a Certificate of Single Status notarized?
Thais: obtain from your district office → certified translation → MFA → foreign spouse's embassy. Foreigners: sign an Affidavit of Single Status before a Thai attorney or your embassy → MFA → present at Thai district office to marry.
What corporate documents are needed to open an account or register abroad?
Standard pack: (1) DBD company affidavit ≤30 days, (2) BOJ 5 shareholder list, (3) MOA, (4) meeting minutes authorising the transaction, (5) POA to the overseas signer, (6) directors' passports. All notarized → MFA → destination embassy (or Apostille).
What should an expat in Thailand bring for notarization?
(1) Original passport + current-visa page copy; (2) proof of Thai address (lease or utility bill); (3) original documents to notarize; (4) certified translation first if the document is not in English/Thai; (5) tell us the destination country so we can advise the correct chain (Apostille vs. embassy).
