Corporate and director mandates
Mandates signed by directors named in the DBD company affidavit, attaching the affidavit and company seal, keeping the scope narrow, and sub-delegation.
What must a company attach when it authorises an employee?
A mandate signed by the directors with signing authority as shown in the DBD company affidavit, with the company seal if the affidavit requires one; the affidavit itself dated within the period the recipient accepts (commonly one to six months); copies of the directors' and agent's identity documents; and full stamp duty.
Is sub-delegation allowed?
Only if the first mandate expressly grants the power to sub-delegate. Without that wording the attorney-in-fact cannot appoint anyone else. Recipients normally want to see the whole chain at once, and in practice multiple layers of sub-delegation sharply raise the chance of rejection.
How does a foreign director sign a Thai mandate from abroad?
Sign before a notary public in the country of residence, then follow that country's chain — an Apostille if it is a convention party, otherwise foreign-ministry legalisation followed by Royal Thai Embassy certification — then have the document translated into Thai with the translation certified by the Department of Consular Affairs before filing in Thailand.
How do I write a consent letter for a child to travel abroad?
The non-travelling parent should state the child's name, passport number, destination, travel dates, who will accompany the child, and contact details, and sign before a Notarial Services Attorney in Thailand or a Royal Thai Embassy officer abroad. Some destinations also want the letter translated into their language and legalised.
How can I reduce the risk of granting a power of attorney?
Keep the scope as narrow as the job allows, put an expiry date in the document, expressly prohibit sub-delegation, state a minimum price where an asset is being sold, keep a copy of every mandate with a note of who holds it and since when, and notify authorities immediately when you revoke it.
What must a foreign company attach to its power of attorney?
Besides the mandate itself: a certificate of incorporation issued within the last six months, the list of directors, and a board resolution approving the delegation. The whole bundle is legalised abroad by the same route as the mandate, translated into Thai and the translation certified by the Department of Consular Affairs, before filing with the Department of Business Development or another receiving authority.
What is special about mandates filed with the Department of Business Development?
Use the mandate form attached to the department's registration application and list the exact filings delegated — changing directors, increasing capital, moving the registered office. The principal must be a director with binding authority per the company affidavit, stamp duty must be paid, and certified copies of ID or passport attached.
Can my attorney-in-fact delegate the authority to someone else?
Only if the original document expressly permits sub-delegation. Without that clause the appointed person cannot appoint a substitute and the substitute's acts may not bind you. Where sub-delegation is allowed, the original instrument must be produced together with the sub-power, and the sub-power cannot be wider in scope than the original. Thai authorities examine this point carefully because it is a common route for misuse.
What must accompany a foreign company's power of attorney used in Thailand?
Evidence that the signatory can bind the company: a recent certificate of incorporation or company extract, the board resolution or minutes approving the appointment, and specimen signatures. The signature is notarized in the issuing country, authenticated by the local authority and the Royal Thai Embassy, then translated into Thai and legalized in Bangkok. Ensure the company name and registration number match on every document, and that the resolution is dated no later than the power of attorney itself.
Can your team review my draft power of attorney before I sign abroad?
Yes, and that review is where most delays are avoided. We compare your actual objective with the form the receiving office uses, calibrate the scope so it is neither dangerously broad nor unusable, check stamp duty, the number of originals, witnesses and translation requirements, then sequence the cross-border certification so it completes in one round. Our team has more than 15 years of experience with land, corporate, litigation and consular files. Send us the draft or simply describe your goal and we will map the steps before you sign.
May the attorney-in-fact delegate the power to someone else?
Only if the instrument expressly allows sub-delegation. Without that clause most authorities refuse the substitute and the acts may not bind the grantor. If the appointed person may become unavailable, include a sub-delegation clause naming the permitted substitute or their qualifications, and require written notice to the grantor each time it is used.
Which corporate papers accompany a foreign company's power of attorney for use in Thailand?
Evidence that the signatory can bind the company: a certificate of incorporation recent enough for the receiving authority, board minutes approving the appointment, and specimen signatures of the directors. The whole set must be certified in the country of origin and translated into Thai. The most common rejection is a company name transliterated differently from the spelling already registered with Thai authorities.
What causes most rejections?
Five recurring causes: name spelling that differs from the passport by even one character; authority so broad the receiving officer cannot interpret its limits; missing proof of the corporate signatory's authority; certification steps performed out of order, such as translating before the original is certified; and documents older than the accepted window. Reviewing the draft and the certification sequence before signing removes most of this risk.
