The Thailand legalization chain

Four steps, one clear path to a Thailand-ready document

Thailand is not a member of the Hague Apostille Convention, so a US apostille is not accepted. Documents must be authenticated in order and legalized by the Royal Thai Embassy. The same chain applies to commercial and residential documents alike — including US Department of State authentication.

legalization

→ US Department of State authentication is required for all documents — commercial and residential. We pay the embassy fee directly by check and submit by mail. The final Thai embassy attestation step takes about 2 weeks because submissions are accepted by mail only, after the earlier authentication steps.

Before you submit

The Royal Thai Embassy requires a copy of the signer or applicant's photo ID with the submission. And if your document is in Thai, it needs a certified English translation before the US Department of State step. We confirm both before we go.

Two ways to go

Standard or expedited — we handle everything either way

You hand us the document and we do the rest — notarization, Secretary of State and US Department of State authentication, and Royal Thai Embassy legalization. The final Thai embassy attestation step takes about 2 weeks because submissions are accepted by mail only, after the earlier authentication steps. Trust the professionals and skip the guesswork.

Where people get rejected

The mistakes that get documents rejected

Most Thailand rejections come from a handful of avoidable errors. We review these before your document is submitted by mail. The final Thai embassy attestation step takes about 2 weeks because submissions are accepted by mail only, after the earlier authentication steps.

★ Easy to miss

Missing the signer's photo ID

The Royal Thai Embassy requires a copy of the signer or applicant's photo ID with the submission. Leaving it out holds up the whole file. We confirm it's included before we go.

✕ Sequence

Skipping US Department of State

Thailand requires US Department of State authentication for every document — commercial and residential. Sending a document to the embassy without it, or out of order, gets it rejected.

✕ Content

Incorrect stamps or signatures

Every prior seal in the chain must be valid and in the right order. A single incorrect signature or stamp anywhere invalidates the submission.

✕ Translation

Thai-language document without English translation

If your document is in Thai, it needs a certified English translation before the US Department of State step — US Department of State won't authenticate a Thai-language document. We confirm this before it moves through the chain.

Certified Thailand Translation

Some Thailand authorities require documents to be translated into Thai before they can be accepted. We provide Certified Thailand Translations that are fully embassy-approved, ensuring your documents meet Thailand legal standards. Translations are accurate, professional, and accepted by government offices, schools, and businesses in the Thailand.

  • This service is amazing! I wish I had known about it sooner. I had a document to be used abroad that needed to be notarized AND needed an apostille. It’s not so hard to find a notary but for anything more complicated, Aziz can get it done with a minimum of effort on the client’s part. He picked up the document, handled the legalizations process and returned the document to me. And in less than 24 hours! The consulate, which was my only other option had a ridiculous wait time to even get an appointment,  not to mention they were going to charge me three times what Aziz did. His rates are reasonable and he is super-professional and efficient! He saved me so much time and navigated the whole process seamlessly for me.  I highly recommend him and will no doubt be calling on him again in the future.

  • DC Mobile Notary was fantastic. Super easy to schedule and super flexible. Best prices I found as well. Danyar was quick, efficient, and super friendly. I’d absolutely use them again!

  • I was impressed with this company from start to finish, and I will definitely go to them again when I need a notary.First, it was super easy to set up the three appointments that I needed; the receptionist was able to confirm the appointments while I was on the phone with her.  Second, the notary showed up right on time for all appointments, even in one city location during rush hour and where finding street parking was challenging.  Even when I needed to change the location of one appointment at the last minute (from a Starbucks that wasn't open yet to a nearby restaurant), it was easy to reach the notary himself and work out the change with him.  Third, the two notaries I dealt with were both professional in appearance and manner.  Finally, company can cover DC, MD, and VA where I do business, and their price is reasonable.I'm very grateful that the paperwork went smoothly and was done properly.  I'm a new fan of DC Mobile Notary.

  • Aziz of DC MOBILE Notary was incredibly patient, knowledgeable, friendly, and reliable with regard to services we needed to authenticate educational documents for use abroad.  I will no hesitate to utilize his services again. In today's world of everything automated and voice bots, Aziz was a breath of fresh air, answers calls and emails without delays and works on finding solutions for his clients. Thanks Aziz.

What Is Thailand Embassy Legalization (Attestation)?

Since Thailand is not part of the Hague Apostille Convention, your U.S. documents must go through a multi-step authentication process before they can be officially recognized in Thailand. We manage each authentication stage and submit the final embassy attestation by mail. The final Thai embassy attestation step takes about 2 weeks because submissions are accepted by mail only, after the earlier authentication steps.

Answers

Thailand legalization, answered

Does Thailand accept a US apostille?

No. Thailand is not a member of the Hague Apostille Convention, so a US apostille is not accepted. Documents must go through full legalization: notarization if needed, Secretary of State authentication, US Department of State authentication, and Royal Thai Embassy legalization.

What is the process to legalize a US document for Thailand?

The document is notarized if needed, then authenticated by the Secretary of State in the issuing state, then by the US Department of State in Washington, DC, and finally legalized by the Royal Thai Embassy. The same chain applies to commercial and residential documents. A copy of the signer or applicant's photo ID is required with the submission.

Do commercial documents need US Department of State authentication for Thailand?

Yes. Thailand requires US Department of State authentication for every document — both commercial and residential. There is no shortcut that skips the federal step, so every document passes through Secretary of State, then US Department of State, then the Royal Thai Embassy.

How much does Thailand legalization cost?

Our service starts at $495 per document, with standard and expedited options. Separately, the Royal Thai Embassy charges its own legalization fee of $15 per document. Embassy fees are set by the embassy and may change; we confirm the current fee with your quote. US authentication and certified translation, if needed, are quoted with your all-in price.

What do I need to submit a document for Thai legalization?

You need the original document, and the Royal Thai Embassy requires a copy of the signer or applicant's photo ID with the submission. If your document is in Thai, it needs a certified English translation before the US Department of State step, since US Department of State will not authenticate a Thai-language document. We review your document up front to confirm everything is in order before it enters the chain.

Do you handle the whole Thailand legalization process for me?

Yes. We handle notarization, Secretary of State and US Department of State authentication, and Royal Thai Embassy legalization as a single service, and we pay the embassy fee on your behalf. The final Thai embassy attestation step takes about 2 weeks because submissions are accepted by mail only, after the earlier authentication steps. You hand us the document once and receive it back fully legalized. Start with a free document review.
