Q1150. What attestation protocols apply to foreign asset and business valuation reports?

Answered by the NYC Visa & Translation legalization desk

Valuation reports need an attestation route tailored to their author and intended Thai use. Ask the receiving court, regulator, lender, or transaction authority whether it accepts the foreign valuer’s qualifications and requires an original signed report, certified copy, or sworn declaration. Because many reports are private professional documents, the valuer’s signature may need notarization before origin-country authentication and Thai embassy legalization. Confirm whether Thai translation and subsequent Department of Consular Affairs processing are required, including treatment of schedules and appendices. Legalization authenticates the relevant signature or seal, not the valuation methodology or stated asset value. A common pitfall is authenticating only a cover letter when the recipient requires the signed report and supporting schedules. Verify the attestation scope with the receiving Thai authority before filing.
