ROYAL THAI EMBASSY ROUTE UNTIL FEB 2027
Registering a marriage at a Bangkok amphur, starting a job on a Thai work permit or appointing a director to a Thai company? Our Thailand document legalisation Singapore service takes your Singapore papers through our partner Notary Public, the Singapore Academy of Law and the Royal Thai Embassy.
We match each document to what the Thai office asked for, check that names agree with your passport, and tell you how the Thai translation and the final legalisation in Bangkok will be handled once the papers arrive.
Tell us the document and which Thai office will receive it, and we reply with the route, price and dates before any work starts.
Not until 28 February 2027
Thailand joined the Apostille Convention on 30 June 2026, and it takes effect for Thailand on 28 February 2027. Until then, Singapore documents still need Royal Thai Embassy legalisation in Singapore, then legalisation by the Department of Consular Affairs in Bangkok.

Where Thailand asks
Thai district offices, the Immigration Bureau and the Department of Employment usually want proof that a Singapore document is genuine before they rely on it. Royal Thai Embassy legalisation gives them that proof in the situations below.
A district office (amphur or khet) needs your legalised marital status papers before it registers a marriage in Thailand.
Thai nationals who married in Singapore record the marriage at their district office using a legalised Singapore marriage certificate.
The Department of Employment and many Thai employers ask for a legalised degree or experience letter before a work permit is issued.
The Immigration Bureau checks legalised marriage and birth certificates for Non-O visas and yearly extensions based on family ties.
The Department of Business Development and BOI filings need legalised ACRA records, resolutions and powers of attorney from a Singapore shareholder.
A Thai Land Office usually accepts a power of attorney signed in Singapore only after it has been legalised for Thailand.
Thai schools, universities and teaching licence applications may ask for a legalised Singapore degree, transcript or birth certificate.
Thai courts and banks ask for legalised affidavits, divorce papers or company mandates before acting on them.

The route
Thailand adds a step after the embassy, unlike our Malaysia document legalisation route. Until 28 February 2027, Thai consular legalisation runs through these stages.
Our partner Notary Public notarises private and company documents, while Singapore government records skip this stage.
The Singapore Academy of Law authenticates the notary's signature or the official's seal on the document.
We lodge the document at the Royal Thai Embassy in Singapore during its Monday to Thursday morning window and collect it once legalised.
We hand the legalised document to you in Singapore or courier it to you, your employer or your agent in Thailand.
In Thailand, the document is translated into Thai and legalised by the Department of Consular Affairs before the Thai office accepts it.
Documents
Personal, education and company records all pass through Royal Thai Embassy legalisation, each starting from the step its issuer requires.
Marriage, birth and divorce records used for amphur registration, family visas and school places in Thailand.
Degrees, transcripts and police certificates that Thai employers and the Department of Employment check for work permits.
ACRA records and board decisions that a Singapore parent company sends for a Thai subsidiary or BOI project.
Powers of attorney that let a lawyer, relative or manager deal with a Thai Land Office, bank or company registry for you.
Free check for Thailand
Forward the list from your employer, district office, visa agent or lawyer in Thailand, and we confirm the Royal Thai Embassy legalisation each item needs, with the price, before any work starts.
What it costs
Pricing for Royal Thai Embassy legalisation follows the steps your document needs, with the Singapore government fee built into each step. The embassy fee is passed on at cost and shown in your quote.
Paid separately: the Thai translation, the Department of Consular Affairs fee paid in Thailand, courier to Thailand and urgent handling, each quoted before you confirm.
Timeline
Planning backwards from your Thai visa, work permit or amphur date is how we run document legalisation from Singapore, and for Thailand the embassy stage has fixed lodging days that shape the whole plan.
Is your Thai deadline after 28 February 2027? Our SAL apostille service should then replace the embassy stage, so tell us your date before you order.
Before we begin
Gathering these items first keeps your Thailand legalisation on schedule and avoids missing the embassy's weekly lodging window.
Tell us before lodging if your passport, certificate and any Thai paperwork spell your name differently, so we can add a one-name declaration from our partner Notary Public.
Courier your Singapore original to us and we send it back legalised, as part of our legalisation from overseas service.
Avoid a rejection
Small gaps in Royal Thai Embassy legalisation often surface only in Bangkok, and documents in another language also need an English translation for legalisation before the embassy will take them.
✕ Sending an SAL apostille alone before 28 February 2027
✓ We add the Royal Thai Embassy stage until the Convention takes effect for Thailand.
✕ Lodging a non-English document without its translation
✓ We bind the English translation to the original under our partner Notary Public's seal, as the embassy expects.
✕ Planning a Friday drop-off at the embassy
✓ We time SAL so the document reaches the embassy within its Monday to Thursday morning window.
✕ Forgetting the Bangkok step after the embassy
✓ We explain the Thai translation and Department of Consular Affairs step before your papers leave Singapore.
FAQ
These answer the doubts people raise just before ordering Thailand legalisation from Singapore.
Ask On WhatsAppIt should be, as the Convention does not cancel legalisations already completed. Some Thai offices still want a recently issued document, so check how old they allow it to be before you order early.
Yes for many Singapore government records, as the Royal Thai Embassy in Singapore can verify a Thai translation of them for its own fee and in about 4–6 days. Many clients prefer to have the translation done in Thailand, where the Department of Consular Affairs checks it anyway.
Use the same Thai spelling across every document, matching your visa and work permit records. Different spellings on a marriage certificate and a work permit can lead an office to ask for a correction.
A relative, your employer or a Thai agent can book the Department of Consular Affairs appointment for you. They usually need an authorisation letter and a copy of your passport.
Land Offices usually want their own power of attorney form, so ask the office or your Thai lawyer for it first. You then sign that form before our partner Notary Public in Singapore and we legalise it for Thailand.
Thai immigration usually asks for legalised birth certificates to prove the family link. International schools often accept a plain copy, so check with the school before legalising extra copies.
No, the embassy returns it, but we usually legalise a certified copy so your original stays safe. Ask your Thai employer first if it insists on the original.
Your Singapore marriage certificate goes straight to SAL and then the Royal Thai Embassy, with no notary stage. You then record the marriage at your district office in Thailand with a Thai translation.
Send a scan and tell us which office in Thailand asked for it. We confirm the route, the 2027 timing and your price before any work starts. You can also read our client reviews first.
