Simplifying the Thailand Document Legalization Process

Our team handles the entire Thailand Document Legalization chain, beginning with local notarization and authentication through the Washington, DC Secretary of State. The documents are then authenticated at the U.S. Department of State and finally submitted to the Royal Thai Embassy for the final stage of legalization.

Whether your documents are needed for personal, academic, or business purposes, Monument Visa provides a fast, efficient, and professional Thailand Document Legalization service to ensure your documents are properly recognized for use in Thailand.

Step-by-Step Guide to Thailand Document Legalization

Our four-step process makes document legalization for Thailand simple and stress-free. We start with local notarization for general documents, then proceed to state authentication, and for federally issued documents, we skip directly to U.S. Department of State submission. Finally, all documents are processed through the Thailand Consulate for legalization, ensuring they meet the legal requirements for use in Thailand. Let us handle the complexities while you focus on what matters most.

📋

Step 1: Notarization (If Required)

Most personal or business documents must first be notarized by a U.S. notary public.

Examples include:

  • Educational Documents (Diploma / Transcripts / Certificates)
  • State/local issued criminal reports
  • Business documents

Note: Federal government documents (such as FBI background checks) do not require notarization and can move directly to Step 3.

✅

Step 2: Washington D.C. Secretary of State Authentication (1–2 Business Days)

Once your document is notarized, it must be authenticated by the Secretary of State where the notarization occurred.

Important:

  • Vital records such as birth, marriage, or death certificates must first be authenticated by the Secretary of State in the state that issued the certificate before sending them to Monument Visa. However, we can only service the states within the jurisdiction of the Washington D.C. Thai Consulate. Please click here to view the jurisdiction list.
  • If you choose to complete the notarization and Secretary of State authentication in another state, you will need to mail the original notarized and authenticated document to our office so we can continue with the remaining legalization steps.

Step 3: U.S. Department of State Authentication (Approximately 2 Weeks)

Once state authentication is complete (if required), documents are submitted to the U.S. Department of State in Washington, DC for a federal authentication.

🏁

Step 4: Thailand Embassy Legalization (Approximately 2–3 Weeks)

Finally, the documents are submitted to the Royal Thai Embassy for legalization. Once completed, your documents are officially recognized for use in Thailand.

Honest, easy and super reliable! Did exactly what they said and in the exact time they promised. Called when I had a question, and not only talked to a human but the owner himself. Highly recommend.

Got my apostille in exactly the allotted time I was given and they were very easy to work with. If you need a federal apostille sent sooner than 6 weeks these guys are worth every penny!
