What are the most common reasons a translation is rejected?

In-depth Answer

Judging by the request-for-information patterns that recur, rejections fall into three groups.

First, inconsistent personal data: a name spelled differently across two documents, a date of birth that differs between the birth certificate and the ID card, or a botched Buddhist-era conversion.

Second, incompleteness: only the front of a page translated while the reverse carries a seal, blank pages skipped without a note, or seals and signatures on the source left undescribed.

Third, defects in the certification itself: a stamp with no CPN, a credential that expired before the signing date, or a stamp stating English-into-Thai when the job was Thai-into-English.

All three are preventable with a pre-lodgement check and a provider who is happy for you to verify their credential number.
