A commercial contract or memorandum of understanding — what should you know about powers of attorney and stamp duty?

The scope of this answer is “A commercial contract or memorandum of understanding”, so it deals with the case-specific points first and the shared rules afterwards. When several certification layers are required, start with the slowest one. For documents going abroad, include international shipping time in the plan. Before starting, ask in advance which category of certified translator the destination accepts, then plan the timeline so certification finishes before the real filing deadline, then keep a digital copy of every page, including seals and signatures. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. What sets this case apart is the number of certified sets and the window in which they must be used. The terms that frame this page are commercial · contract · memorandum · understanding. The specifics here are document type: Contract, and those decide which translation and certification level applies. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. Note who signed each certification and on what date for later reference. Keep a copy of every source document plus the receipt or docket from each step. A power of attorney is governed by the agency provisions of the Civil and Commercial Code and must bear stamp duty under the Stamp Duty Schedule of the Revenue Code; state the scope, the validity period and the attorney's name exactly as in the passport or ID card, because the receiving side checks the names character by character. Only directors signing in the manner stated in the company certificate — the required number of joint signatories and the company seal where noted — can bind the company; a signature that does not match those conditions is usually rejected by the bank or authority at the checking stage. Where the destination asks for a director's signature to be witnessed, a certified true copy, or a certified translation, a Notarial Services Attorney licensed under the Lawyers Council of Thailand's regulations can certify it; Thailand has no common-law notary public office, so this is the equivalent domestic channel. ILC handles document work only — translation, certification of the translation, notarial signature certification and the legalisation run at the Ministry of Foreign Affairs and embassies. ILC is not a registrar, auditor or tax adviser and cannot guarantee the decision of any authority or counterparty. Cost and lead time depend on page count, the language pair and the certification steps the destination requires, so every file is quoted before work starts.
