Certified Thai Translation Services for Documents
Corpus provides certified Thai-to-English written document translation with a signed Certificate of Accuracy. Eligible clear standard files start at $19.99 per page. Complex records, unclear scans, packets with front-and-back content, and files with recipient-specific instructions need quote review before work begins.
Thai records need more than text copied from an OCR tool. Thai words are generally written without spaces, vowel signs can appear visually before the consonant they follow in pronunciation, and official records may combine Thai numerals, Buddhist Era dates, stamps, seals, and handwritten annotations. Our process compares the English translation with every visible part of the supplied source rather than guessing from extracted text.
Have a clear, complete standard document with a known page count? Start your order at $19.99 per eligible page. For a house-registration packet, faint seals, handwriting, damage, mixed languages, an uncertain page count, or special recipient instructions, request a document review and quote. You can also review current pricing and eligibility or browse the full language directory.
What Thai documents can be translated?
Thai-to-English translation can cover readable civil, identity, police, and academic records when the complete source file is supplied.
Common Thai civil records include birth certificates (Sutibat), marriage registrations or certificates (Tabien Somros or Bai Samkhan Kan Somros), divorce records, death certificates, name-change certificates, national identity cards, house or civil-registration records, and police certificates. District registration offices, often called Amphur offices, issue many Thai civil records. Formats and markings differ, so the translation must follow the document in front of us rather than assume every Thai record uses the same layout.
A Thai birth record may support an immigration or family filing, but the receiving agency decides which document and certification it requires. See our birth certificate translation service and USCIS translation service for related process guidance. Marriage and divorce packets may include more than one record, so buyers should also review marriage certificate translation and upload all relevant pages.
Thai diplomas and transcripts may be used for school admission, employment, licensing, or credential evaluation. Academic translation services cover readable education records, while the school or evaluator sets its own submission rules. Police and court records may be requested by a court, attorney, employer, licensing body, or immigration authority; our criminal record translation service explains that document category. Corpus translates supplied written documents. We do not obtain records or decide which records a recipient needs.
How are Thai names transliterated into English?
Thai names are rendered with one consistent, source-supported Latin spelling across the translated packet.
A Thai name can have more than one reasonable Latin spelling. A buyer should provide the spelling used on the passport or other recipient-facing identity record. That spelling may guide the translation only when the Thai source supports the same identity. It cannot replace a different person, change a source fact, or override text that the source does not support.
Consistency matters when a packet contains a birth certificate, national ID, marriage record, divorce record, and name-change certificate. The translation should preserve the sequence shown by the records, including former names and visible name-change details. If English spellings differ across documents, flag the difference during intake instead of silently making the records appear identical. A passport spelling is a reference point, not permission to rewrite source content.
Upload identity pages or recipient-facing spellings that are relevant to the same person. If the source is unclear, damaged, handwritten, or conflicts with the requested spelling, the file goes to quote review so the uncertainty can be addressed before translation.
How are Thai Buddhist Era dates handled?
Each source date is preserved and paired with a verified, consistently formatted English or Gregorian equivalent when needed.
Thai records may use Thai numerals, Buddhist Era dates, Gregorian dates, or more than one system in the same packet. Date handling begins with the visible source. The translation should identify the date system, preserve the source information, and apply the same verified English rendering throughout the document set.
No automatic conversion should be used when a date is ambiguous, handwritten, damaged, partly hidden by a stamp, or mixed with another date system. Day, month, and year order must not be silently rearranged. A date on a Thai civil record can affect how a name-change sequence, marriage history, school record, or identity record is understood, so unclear dates are marked for review rather than guessed.
Send all pages that show dates tied to the same event. If a continuation page or back side explains a registration date, amendment, or issue date, include it in the upload. Uncertain dates or conflicting date formats require a quote before scope and turnaround are confirmed.
What should a complete Thai document scan include?
A complete upload shows every edge, side, page, mark, annotation, and readable field in straight, well-lit color images.
Include the front and back of each record, even when one side appears mostly blank. Show Garuda or other official marks where present, embossed or faint seals, stamps, marginal notes, signatures and their labels, handwriting, registration numbers, continuation pages, and page numbers. Do not crop the top, bottom, corners, or binding edge. Photograph pages squarely so text and marks are not distorted.
Thai script requires careful visual comparison because words commonly appear without spaces and marks may sit above, below, before, or after consonants. OCR can miss boundaries, split marks from letters, or misread faint text. Every readable field should be checked against the image. Unreadable content should be marked as unreadable, not reconstructed from context.
Blur, glare, deep shadows, folds, damage, dense seals, handwriting, cropping, mixed languages, or an uncertain page count can change scope. These files belong in quote review. A clear scan protects names, dates, registration numbers, and official annotations from avoidable transcription errors.
Should I order directly or request a quote?
Order a clear, complete standard file with a known page count; request a quote for anything complex, unclear, or recipient-specific.
Start Your Order is for an eligible clear standard document with all pages and sides included and a known page count. Direct-checkout pricing is $19.99 per eligible page. A 24-hour delivery option is available only for qualifying clear standard files after the scope is confirmed.
Get a Quote for house-registration or civil-record packets, multiple records, fronts and backs, handwriting, older or damaged documents, faint or dense stamps and seals, glare, shadows, cropping, mixed languages, complex formatting, an uncertain page count, or instructions from a specific recipient. Quote review confirms what is included before translation begins.
Corpus focuses this service on certified Thai-to-English written-document translation. Interpretation, legal advice, document procurement, notarization, apostille service, mailed hard copies, and immigration or recipient outcomes are outside this service. If you need another translation direction, submit the file for review rather than assuming direct-checkout eligibility.
Who decides whether a certified translation is accepted?
The receiving organization sets its requirements and makes the final acceptance decision.
For USCIS submissions, a foreign-language document generally needs a full English translation with a certification that the translation is complete and accurate and that the translator is competent. USCIS does not approve translation vendors, and a translation cannot guarantee an immigration result. NVC, an embassy or consulate, a court, school, credential evaluator, DMV or licensing body, bank, insurer, employer, or other recipient may apply different rules.
Match the workflow to the document. Thai birth, marriage, divorce, death, and name-change records may be submitted in immigration or family matters. Police and court records may go to a court, counsel, employer, licensing body, or immigration authority. Diplomas and transcripts may go to schools or credential evaluators. National ID, name-change, and house-registration records may be requested by government offices, banks, insurers, employers, or consular staff.
The recipient decides whether it needs certification, originals, copies, a specific format, or additional records. Confirm those instructions before ordering. Corpus translates the complete readable file you supply and provides the signed translation certification; it does not provide legal advice or promise acceptance.
