Where can I get paperwork notarised in Thailand to send back to the U.K.?

In Thailand, notarization is not common, and there are typically no notaries. Instead, authorized solicitors may be acceptable for your paperwork. It is advisable to check with the recipient of the documents regarding their requirements. For document stamping or translation, services like Chiangmai Attorney at Hillside Plaza 4 have been recommended. In Bangkok, searching for local services can yield many results, such as a location near Terminal 21, where costs for notarization services are about 1500 baht.
