Corporate Notarization — Documents, steps & acceptance checks
Corporate Notarization: Check director authority and any seal or joint-signature conditions before certifying the signature or copy.

Documents to prepare
Provide current company records, signing conditions, board authorization and the director’s original ID.
Service-specific checks
Check director authority and any seal or joint-signature conditions before certifying the signature or copy.
Which authentication route applies?
Before 28 February 2027, Thai documents use the existing legalisation route: issuing authority or Notarial Services Attorney when needed → Thai MFA → destination embassy only where required. Not every public document needs notarisation. From 28 February 2027, an Apostille may replace consular legalisation for eligible public documents where the Convention applies between Thailand and the destination. Check objections, exclusions and the recipient’s current rules before filing.
Before sending originals
Check passport spelling, all pages and seals, the recipient’s document-age rule and whether the issuer must send the record directly. Keep a copy of the recipient’s instructions. Avoid sending unrelated sensitive records in the first enquiry.
Fees and authority queues
Service fees depend on document type, translation language, volume and the confirmed route. Government, embassy and courier charges are separate items in the written quote. Authority queues and requests for corrections affect timing; confirm an estimate for the actual file.
Limits of certification
Certification does not validate the board decision or authorize the transaction under foreign law.
Preparation and filing
- 1. Prepare the recipient’s checklist and documents.
- 2. Check director authority and any seal or joint-signature conditions before certifying the signature or copy.
- 3. Confirm the applicable authority steps before submission.
- 4. Review the returned documents against the agreed checklist before delivery.
Questions before filing
Does certification guarantee acceptance?
Certification does not validate the board decision or authorize the transaction under foreign law. No. Authentication verifies a relevant signature or seal, not document contents or eligibility. The receiving authority decides acceptance and may request further evidence.
Can I complete everything by courier?
Not always. Sending scans can help with preliminary review, but signature witnessing requires the signatory’s appearance as required. Original comparison and recipient rules may require original documents. Confirm before posting.
