A working guide to thai digital & electronic signatures in Thailand

Thai Digital & Electronic Signatures can involve different document checks depending on the receiving authority. Confirm the intended use and destination before arranging translation, a notarial signature, or consular legalization. For a review of your specific Thai businesses digitising contracts and tax invoices matter, contact us on LINE @THAIL or by email at Contact@thailaw-accounting.co.th.

Documents to discuss for Thai businesses digitising contracts and tax invoices may include director's ID / passport, company affidavit, e-KYC video capture, existing contract templates, workflow diagram, power of attorney; confirm the final checklist with the receiving authority. Check the current acceptance criteria with the ETDA and Thai Certificate Authorities.

How the workflow runs end-to-end

First identify the issuing authority, the person signing, the destination and the receiving body's current requirements. The necessary steps may include translation, certification or consular legalization, but not every document needs every step. Confirm the sequence before sending originals.
