End-to-end service for any Power of Attorney (POA) that must cross a border — bilingual TH/EN drafting, Notari
Drafting, notarisation and full legalisation of cross-border Powers of Attorney — outbound and inbound
End-to-end service for any Power of Attorney (POA) that must cross a border — bilingual TH/EN drafting, Notarial Certification by a Lawyers-Council-registered Notarial Services Attorney, MFA Legalisation at the Department of Consular Affairs, destination-embassy legalisation (or Apostille for the destination state when Thailand-issued documents transit through a Hague-Convention jurisdiction), and inbound legalisation that makes a foreign POA usable at the Thai Land Department, courts, banks, DBD, Revenue Department, or amphur. Anchored to the Thai Civil & Commercial Code §§ 797–832 (Agency), the Lawyers Act B.E. 2528, and MFA Regulation B.E. 2539. We DO NOT guarantee the outcome of the destination authority — we engineer the chain so that it aligns with published criteria and reduces refusal risk.
A Power of Attorney (POA) lets a Principal authorise an Agent / Attorney-in-Fact to act on the Principal's behalf within a defined scope. The moment a POA crosses a border it becomes orders of magnitude more complex than a domestic one, because the destination authority must be able to verify the signature, the seal and the authority of the certifying lawyer — that verification happens through a chain that runs through the Thai Department of Consular Affairs (Ministry of Foreign Affairs) and either the destination embassy in Bangkok or an Apostille issued under the Hague Convention 1961.
The most common failure mode is downloading a generic template, signing it at an amphur or with a lawyer who is not on the Notarial Services Attorney register, and walking into MFA: it is refused on the spot because the lawyer's specimen signature is not in the MFA database, or the destination embassy rejects the content because it does not match the form they accept. Either way the principal loses 2–4 weeks and the filing fees — and sometimes a Land Department or court deadline at the destination.
Our service is delivered by an attorney registered as a Notarial Services Attorney with the Lawyers Council of Thailand (verifiable at /trust/credentials), with 1,200+ international POAs filed across 67 jurisdictions since 2017. We draft to the destination form (Tor.Dor.21 for Thai Land Department, court-specific forms, foreign-bank house forms), certify under the Lawyers Act B.E. 2528, and coordinate MFA + every embassy in Bangkok. quote on request (phone / LINE / email) Professional Indemnity Insurance, PDPA Section 24 compliance (passports / contracts / family data treated as sensitive personal data), ISO/IEC 27001 servers in Thailand with AES-256 at rest and TLS 1.3 in transit.

Trust & safety (E-E-A-T + YMYL)
Can a Thai POA be used directly in the United States?
Not directly. The US is a Hague Apostille state but Thailand is not (as of 2026), so a Thai POA destined for the US still needs the 4-link chain: Notarial Certification → MFA Legalisation → US Embassy Bangkok (USD 50/document) → use in the US. Total elapsed time: 5–10 business days.
Can an amphur lawyer or a general attorney certify an international POA?
No. MFA only legalises signatures of attorneys registered as Notarial Services Attorneys with the Lawyers Council and present in the MFA Specimen Signature Database. A general practising attorney has no authority to certify documents for foreign use, regardless of license seniority.
Can a foreigner abroad sign a POA to sell land in Thailand?
Yes. Sign before a Notary Public in the country of origin → Apostille or legalise with the origin MFA → authenticate at the Royal Thai Embassy → courier to Thailand → MFA re-legalisation → certified Thai translation + MFA translation certification → file as Tor.Dor.21 at the Land Department with a THB 30 revenue stamp. Total elapsed: 3–5 weeks.
How long is a POA valid?
Under CCC § 826 it is valid for the period stated, otherwise until revoked, death, bankruptcy, or incapacity. In practice the Thai Land Department and most banks refuse POAs older than 6 months — we therefore recommend an explicit 3–6 month Validity Period.
General vs Special POA — which should I use?
General POAs delegate broadly and are high-risk; we rarely recommend them. Special / Limited POAs delegate one specific act (e.g. 'sell title deed no. X only') and are the default. We also set Sub-delegation: Prohibited to stop the Agent from re-delegating.
What is the typical all-in cost?
For one outbound POA: drafting quote on request (phone / LINE / email) + notarial quoted on request + MFA express quoted on request + embassy quoted on request = quoted on request in 3–5 days. Add quoted on request for additional languages. Fixed-fee quote in writing before work begins; no hidden charges.
How do I revoke a POA I previously granted?
Issue a written Revocation of POA + notarise + serve on the Agent (registered EMS + email + LINE) and on every authority that received the original (Land Department, bank, court). If the original was legalised and used abroad, the legalised revocation must also be served on the destination authority.
Can a minor (under 20) grant a POA?
Not unilaterally — under CCC § 21 a minor's juristic acts require consent of the legal representative (parents / guardian). The representative signs on behalf of the minor and attaches the birth certificate + representative's ID. For child travel consent, both parents must sign (or one parent with the other's consent / court order).
For a Land Department transaction using Tor.Dor.21, is notarisation required?
It depends on the parties. If both grantor and grantee are Thai nationals signing in Thailand, Tor.Dor.21 + amphur signature certification is enough. If the grantor is foreign or signs abroad, the full outbound / inbound chain is required, with the THB 30 revenue stamp.
How is personal data (passports, contracts, family data) protected?
Sensitive personal data under PDPA Section 24. Stored on ISO/IEC 27001 servers in Thailand, AES-256 at rest, TLS 1.3 in transit, access limited to the responsible attorney and QA team via MFA + audit log. 10-year retention per the CCC limitation, then destroyed under Witness Disposal Certificate. Data-subject rights at dpo@notary.co.th.
Is the first consultation free?
Yes — send the purpose + destination country + a sample document (if any) on LINE. We reply within one business day with a Drafting Plan + Legalisation Roadmap + fixed-fee written quote. No obligation.

Short answer: Company documents such as certificates, board resolutions, powers of attorney and financial statements must be signed by the authorised directors shown on the company affidavit, sealed where required, then have the signature certified by a notarial services attorney before consular and embassy legalisation in the order the receiver requires.

| Criterion | In-house | Our team handles it |
|---|---|---|
| Signing authority check | HR or the company secretary checks it internally | We reconcile the affidavit and seal conditions before printing |
| Resolution and POA drafting | Generic templates that may not match the transaction | Drafted for the actual transaction with wording receivers have accepted |
| Multi-layer filing | Staff make repeated trips between agencies | We run the layers continuously and report status at each one |
| Risk to the closing date | High when a rejection lands near signing day | Screened in advance by a team with more than 15 years in this field |
If you would rather your team not spend days moving files between agencies, we can run the chain from authority check to delivery. Initial consultation is available by phone, LINE or email.

Document and legalization advisers with 15+ years of practice
Before we start, we read your actual documents and confirm the legalization route matches what the receiving authority asks for. During the work we report progress, and after delivery we still answer questions about how to submit the file.
We prepare documents to the requirements of the receiving authority. Any approval decision remains at that authority's discretion.
Send your documents on LINE for a preliminary review, a recommended legalization route and a written quote.
General guidance, not a case-specific determination. Requirements change with agency notices — confirm with the receiving authority before you act.

Answers drawn from real files for owners and buyers who cannot attend in person: getting the POA on the right form, authenticating the signature, and the chain the Land Office expects.
Use the Department of Lands' prescribed power-of-attorney form, completed in full, granting authority that matches the exact transaction — sale, mortgage or transfer. Sign it before an authorised officer abroad, usually a notary public or a Royal Thai Embassy officer, then run it through the certification chain before the original is sent to Thailand for use.
That is a common cause of rejection. Land Office staff check that the authority granted covers the specific act being registered. Name the title deed number, parcel details, the counterparty and the transaction type. Do not cross out or amend the form by hand — if there is an error, issue a fresh original instead.
In practice: sign before a notary public in that country, have it authenticated by the local competent authority or the Royal Thai Embassy, then translate it into Thai and submit it for legalisation at the Department of Consular Affairs before it goes to the Land Office. Thailand's Apostille Convention takes effect on 28 February 2027; until then the embassy route still applies.
No general statutory expiry applies, but in practice many Land Offices are uncomfortable with a document signed long ago and may ask for further confirmation, including contacting the grantor. Parties therefore usually execute it as close to the transfer date as possible and attach a certified copy of the signed passport page.
Where the property is marital property, a significant transaction normally needs the spouse's written consent. If the spouse is a foreign national living abroad, that consent must be executed and certified exactly like the power of attorney. This is the single most common reason a closing slips — the owner's paperwork is ready but the spouse's is not.
Yes. We review the draft against the Department of Lands' form, arrange notarial authentication of the signature, produce and certify the translation, and run the consular and embassy steps in the correct order. We also advise in advance on the extra documents the receiving Land Office typically asks for. Send document photos to our staff by phone, LINE or email for a review.

Short answer: Land offices refuse powers of attorney that are drafted too broadly, use the wrong departmental form, were signed abroad without Thai embassy and MFA certification, or describe a parcel that does not match the title deed. Redraft narrowly and complete the certification chain.
A single land-office error can cost a month. Our lawyers and advisors draft the PoA to match the transaction, verify the land record, and sequence certification so it clears in one pass.
