Service-specific checks
Confirm who may witness the declaration; draft only facts personally known to the declarant before signing.
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
An affidavit cannot replace an official certificate unless the recipient permits it; false statements carry legal risk.
Preparation and filing
- 1. Prepare the recipient’s checklist and documents.
- 2. Confirm who may witness the declaration; draft only facts personally known to the declarant before signing.

Questions before filing
Does certification guarantee acceptance?
An affidavit cannot replace an official certificate unless the recipient permits it; false statements carry legal risk. 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.
