Why certified translations get rejected — and how to fix it
Short answer: Translations fail on name spellings that diverge from official records, untranslated seals and signatures, Buddhist/Gregorian date conversion errors, and missing translator certification in the recipient's required wording. Reissue a corrected version with the accepted certification statement.
Names or places spelled inconsistently across the bundle
Underlying cause
Documents were translated separately without a shared glossary
Prevent before filing
Fix one spelling standard from the passport and civil registry
How to fix a rejection
Reissue the whole set with consistent spelling
Estimated time cost
Adds roughly 1–4 working days (estimate)
Seals and signatures were not rendered
Underlying cause
The translator skipped non-body elements
Prevent before filing
Require every element to be described, including marginal text
How to fix a rejection
Add seal and signature descriptions and reissue
Estimated time cost
Adds roughly 1–3 working days (estimate)
Dates off by 543 years
Underlying cause
Buddhist-era conversion error or unannotated retention
Prevent before filing
State the calendar explicitly and re-check every date
How to fix a rejection
Correct and reissue with a conversion note
Estimated time cost
Adds roughly 1–2 working days (estimate)
Translator certification wording not accepted
Underlying cause
Each recipient prescribes different wording and translator details
Prevent before filing
Request the recipient's certification statement template first
The recipient also required MFA or embassy certification of the translation
Prevent before filing
Clarify whether certification of the translation itself is required
How to fix a rejection
Run the translation through the prescribed chain
Estimated time cost
Adds roughly 3–10 working days (estimate)
We build a proper-noun glossary for the whole bundle, translate every seal, and carry the certification chain through — send your documents for a pre-check in any language pair.

Service steps at a glance and the documents you need first
A usable translation must mirror the source line by line, spell names exactly as in the passport, and follow the certification format the receiving party requires - a translator's certification, consular legalization in Thailand, or further certification at the destination mission. Confirm that format before translation starts.
