About this language pair

English and Thai: one pair, two directions

From English into Thai you translate for business partners, clients and authorities abroad; from Thai into English for UK authorities, banks and employers. In both directions a native specialist translator with domain experience works on your text.

Where an authority asks for a certified translation, we bring in a sworn translator. The translation carries the required declaration, signature and stamp, and we arrange the Apostille or consular legalisation your destination country demands.

Translation from English to Thai

Translation from English to Thai: we deliver in Standard Central Thai (Bangkok norm), with correct typography respecting Thai's no-spaces-between-words convention. Our DTP specialists set word and line breaks per correct lexical boundaries, which keeps printed material readable and correctly indexed. Sectors we regularly serve: UK-Thai tourism inbound, automotive (Toyota/Honda Thai supply chain), pharma (PMA Thailand) and family reunification dossiers.

Translation from Thai to English

Translation from Thai to English: for UK Home Office casework, family reunification (UK-Thai marriages), notarial deeds, and commercial correspondence. We follow the Royal Thai General System (RTGS) for romanisation of Thai proper names. If the holder already uses a different spelling on a passport, we preserve that spelling.

In practice

How such a project runs

A company opens a branch abroad: website, employment contracts and product documentation go from English into Thai, while incorporation documents and bank records travel the other way. One project manager guards terminology and planning in both directions, and confirms per document whether certification or legalisation is required.

How does Ecrivus handle the absence of spaces in Thai text?
Thai uses no spaces between words within a sentence, only between sentences or clauses. Our Thai translators and DTP specialists set word and line breaks per correct lexical boundaries, critical for readability and indexing.
Will my Thai translation be accepted by the Home Office or UK courts?
Yes, when certified: for UK Home Office and courts Ecrivus delivers certified Thai translations via ITI/CIOL-registered translators.
How does Ecrivus romanise Thai proper names?
We follow the Royal Thai General System (RTGS) for proper names, places, and official terms. Existing spellings on passports or official documents are preserved.
Which document types are standard for English ↔ Thai?
Birth and marriage certificates (family reunification, international marriages), corporate registrations, annual reports, product dossiers, and commercial correspondence. Lead time confirmed in the quote.
