Certified translation, notary and document legalisation in Thailand
Most rejected documents are not badly translated — they are in the wrong order. A foreign certificate usually has to be authenticated abroad before a Thai translation can be certified, and a Thai certificate usually has to be legalised in Bangkok before a foreign embassy will accept it. We check the receiving authority's rules first, then plan every step in one sequence.

Documents we translate most often
Notarial services
Powers of attorney, parental travel consent letters, true-copy certification of passports and degrees, and statutory declarations (for example, confirming two spellings refer to the same person). The signer must attend in person with an original passport, and documents must be signed in front of the notarial attorney.
Frequently asked questions
How do I use a foreign marriage or birth certificate in Thailand?
Usually the document is first authenticated in the issuing country, then legalised by the Thai embassy or consulate there (or that country's embassy in Thailand), translated into Thai, and the Thai translation certified by the Department of Consular Affairs before a district office or immigration will accept it. Confirm the exact sequence with the receiving office.
Does Thai immigration require documents in Thai?
Immigration commonly accepts English for many supporting documents, but documents in other languages normally need a translation, and family-based extensions often rely on Thai civil documents. Requirements differ between offices, so check with the office handling your case.
What does a notary do in Thailand?
Notarial services in Thailand are provided by lawyers registered as Notarial Services Attorneys with the Lawyers Council. They certify signatures made in their presence and true copies of originals. They do not certify that the content of a document is true.
Do you publish prices or guarantee acceptance?
No. We quote after seeing the documents, and acceptance is always decided by the receiving authority.
