Asia & Pacific · Non-Hague Jurisdiction
We coordinate service of process, court filings, and related legal document delivery in Thailand through informal in-person service and, where practical, diplomatic channels, as part of our Asia & Pacific coverage network.
Thailand is not a party to the Hague Service Convention and has no service treaty with the United States. According to the U.S. Department of State, in the absence of a prohibition, service in Thailand may be made by mail, by an agent such as a local attorney, or through Letters Rogatory. Service through a Thai attorney or agent is the method most U.S. litigants use in practice.
Letters Rogatory are the formal route, but they are slow. Because Thai authorities are sensitive to foreign official acts on Thai soil, service is best arranged through a Thai attorney who can make sure it is done in a way Thai law accepts. Documents should be translated into Thai.
Where formal channels to Thailand are unavailable or impractical, we arrange direct delivery of your documents to the defendant's personal or business address, with a sworn affidavit of service on completion.
Discuss this approach →We help prepare the formal request package for the court and manage the diplomatic routing this process requires, including coordination with the U.S. State Department where applicable to Thailand.
Discuss this approach →Where diplomatic channels would be impractical, we help build the factual record needed to support a motion for court-ordered alternative service in matters involving Thailand.
Discuss this approach →Thailand has joined the Apostille Convention, but it only takes effect on February 28, 2027. Until then, U.S. documents that need to be used in Thailand still need full legalization rather than an apostille.
Requirements and current conditions can change — always confirm Thailand's treaty status on the HCCH status table and check current guidance from the U.S. Department of State's judicial assistance page before committing time and court fees to a particular route.
If you expect to enforce a judgment inside Thailand, ask counsel familiar with local law whether the method of service you choose will be respected there — service that satisfies a U.S. court doesn't automatically satisfy a foreign one.
We'll tell you plainly which route looks realistic for your matter, rather than promising an outcome.
Hard-to-serve assignments
Thailand isn't party to the treaties that give U.S. litigants a standard route for serving papers, so the usual channels can be slow or unavailable. We arrange informal service where it's an option, and can locate the defendant first if you don't have a current address.
There is no formal, treaty-based service method for Thailand: it is not a party to the Hague Service Convention or the Inter-American Convention. Letters Rogatory through diplomatic channels can be requested, but they are slow, so many litigants proceed with informal service, or ask the court to authorize alternative service under FRCP Rule 4(f)(3).
We arrange informal service at personal and business addresses across Thailand: a private agent delivers the papers to the defendant or an authorized recipient. In federal cases, Rule 4(f)(2)(C)(i) allows personal delivery of the papers to an individual abroad unless the foreign country's law prohibits it (business defendants are governed by Rule 4(h), so the options differ). Ask your counsel to confirm the method suits your court and, if you expect to enforce a judgment in Thailand, local law.
You receive a sworn affidavit of service recording the date, place, manner of delivery, and the person served. Thailand is a party to the Apostille Convention, so if the affidavit will also be used in Thailand's proceedings, it can be apostilled in the country where it was signed. Tell us early and we'll confirm what your court and any foreign use will require.
Before you proceed: If you expect to enforce a judgment in Thailand, ask counsel whether service made this way will be respected by courts there, since local rules differ from U.S. practice.
The process
We review your case, deadline, and defendant details to confirm whether Letters Rogatory or a Rule 4(f)(3) motion fits better.
The original documents, a request letter, a cover letter, and translations into Thailand's official language(s), typically with a notarized translator's affidavit.
Letters Rogatory must be signed by a judge, not a clerk, and carry whatever seal or authentication Thailand requires.
The request is routed through the U.S. Department of State to Thailand's foreign ministry and courts.
Authorities in Thailand carry out service, and confirmation returns through the same channel for you to file with the court.
Requirements can differ by court and by country, and can change over time — treat this as a general outline, not a checklist for your filing.
Planning your matter
Service arranged through a local attorney or agent is often completed within a few weeks. Letters Rogatory typically take a year or more.
Documents should be translated into Thai. Letters Rogatory require it, and for other methods a translation helps show the defendant understood what was served.
For a defendant in Thailand, the practical choices are personal service arranged through a Thai attorney or agent, mail where your court's rules allow it, or Letters Rogatory through diplomatic channels, which are formal but slow. Where enforcement in Thailand is likely, take advice from Thai counsel on the method.
Process Server Global has handled international service of process since 1982, and Thailand is one of the 195 nations we serve. We manage the paperwork, translations, routing, and proof of service, so your documents reach Thailand through the right channel and come back court-ready.
Request service in ThailandGetting papers served in Thailand usually depends on the right people in the right offices. We work through the diplomatic and judicial channels Thailand recognizes, and coordinate in-country resources where local law allows, so your request doesn't stall on a technicality. If you're considering hiring a single process server directly in Thailand, be careful — agents may not be authorized under a foreign country's law to serve documents there, and service that ignores local rules can be challenged or carry serious consequences. Talk to us first, and we'll confirm what's permitted and which route will hold up.
We serve summons, complaints, subpoenas, and other court documents in Thailand in line with FRCP Rule 4(f), and return proof of service your court can rely on — a diplomatic confirmation or a sworn affidavit of service, depending on the route used.
Thailand has not joined the Hague Service Convention, so requests don't go through a Central Authority. Treaty status can change, so confirm it on the HCCH status table before you file.
Whatever the document, our team has the experience to execute your specific request and route it through the right channel the first time.
Decades of experience working through the correct government and judicial channels — Hague Central Authorities where they apply, diplomatic and court channels where they don't — mean your documents move through the right process, wherever they're headed.
Since 1982, we've built a track record litigators rely on — documented, court-ready service performed to FRCP 4(f) standards.
