Apostille route or Destination embassy legalization route — choosing the right route for legalization at the department of consular affairs
This page compares the two certification routes used for legalization at the department of consular affairs: when each applies, how many layers are involved, which authorities take part, what the translation must look like, and the mistakes that most often send a file back.
| Aspect | Apostille route | Destination embassy legalization route |
|---|---|---|
| When it applies | The destination country is a party to the Apostille Convention | The destination country is not a party to the Apostille Convention |
| Certification layers | Consular Affairs certification, then the Apostille certificate | Consular Affairs certification, then a further endorsement at the destination embassy |
| Authorities involved | Department of Consular Affairs, Ministry of Foreign Affairs | Consular Affairs plus the destination country's embassy or consulate in Thailand |
| Translation | Full translation with the translator's statement of accuracy | Full translation; some embassies prescribe their own translation format |
| Timing factors | Depends on the Consular Affairs queue | Depends on the Consular Affairs queue and the embassy's working calendar |
| Common mistake | Requesting an Apostille the destination does not accept | Skipping the consular layer and filing at the embassy directly |
