requirements-based regulations
Our Sathon office issues receipts and tax invoices under the Revenue Code B.E. 2481 (and amendments) with full 7% VAT — suitable for corporate customers claiming the expense or input tax credit.
Legalization by the Ministry of Foreign Affairs follows Department of Consular Affairs regulations — files must first pass Notary Public, or be Thai government-issued files that the Department recognises.
Apostille procedure follows the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public files. Thailand’s Apostille accession (30 June 2026) only enters into force on 28 February 2027, so files bound for Hague member states must always pass MFA + destination embassy.
Notary Public services in Thailand operate under the Lawyers Council of Thailand Regulation on Registration of Notarial Services Attorneys B.E. 2551 (and amendments), which requires every notarising lawyer to complete training and register with the Council.
