About the Thai language.
Thai is the official language of Thailand. It is written in the Thai script, without spaces between words; spaces mark the ends of phrases and sentences instead.
Thai documents usually give years in the Buddhist Era, which is 543 years ahead of the Gregorian calendar. Dates are translated faithfully, and we can add the Gregorian year where required. Thai names can be written in the Latin alphabet in several ways. We follow the spelling in your passport.
Thai script needs fonts that support it, and line breaking works differently from English. Our desktop publishing team handles Thai typesetting.
Thai to English is usually personal, civil, academic and company documents. English to Thai is usually business, tourism and marketing content.
Common Thai documents include birth certificates, marriage certificates, degree certificates and academic transcripts. A certified translation is available for these. If an authority asks for a sworn translation, ask us to confirm availability for the language pair.
