Thailand acceded to the 1961 Hague Apostille Convention on 30 June 2026; it enters into force for Thailand on 28 February 2027, so Apostilles are not yet issued. Thai documents are legalised at the Department of Consular Affairs, Ministry of Foreign Affairs, and then at the destination country mission where that country requires it.
We keep no permanent office in Ubon Ratchathani — service is by appointment and courier through Khon Kaen Branch.
Ubon Ratchathani has the Chong Mek permanent border crossing into Champasak Province in Laos, as well as its own airport. Local clients therefore bring both cross-border Lao paperwork and family documents that must be sent abroad.
We do not keep a staffed office in Ubon Ratchathani, so the province is served by appointment and tracked courier. Combined with checking whether the temporary passport office at the Provincial Hall currently accepts your type of legalisation, this often removes the need for a trip to Bangkok. We confirm each step with you before originals leave your hands.
Clients who work or have family in Champasak often need documents to work on both sides of the border. Tell us at the start whether a document will be used in Thailand, in Laos, or in a third country, because each route needs a different combination of translation and legalisation. Lao-language originals need a translation that Thai authorities accept before they can be attested here, and Thai documents for Laos usually need Ministry of Foreign Affairs legalisation before the Lao side will accept them.

The destination country is not a party to the Apostille Convention
If the destination is not a party, the document needs consular legalization plus destination-embassy certification instead, so an apostille will not serve. Check the destination’s status before filing.
Filing a copy the issuing office has not certified
The officer must verify the issuing authority’s signature and seal; a self-made photocopy provides nothing verifiable. Obtain a certified true copy from the issuing office first.
The translation omits parts of the document
Seals, signatures and end-notes form part of the original. A translation that drops them is treated as not matching the original and must be corrected before re-filing.
Incomplete authority for the person filing
When not filing in person, a power of attorney with a copy of the grantor’s ID is required, and its scope must cover the specific filing.
We do not keep a permanent office in Ubon Ratchathani. Clients there are served by appointment and courier through Khon Kaen Branch, the nearest permanently staffed branch. We never claim a shopfront where we have none.
In most cases no. Filings with central authorities such as the Department of Consular Affairs or an embassy can be handled on your behalf. Steps that legally require you in person — fingerprinting, or signing in front of the certifying attorney — cannot be delegated.
Turnaround depends on the responsible authority’s queue and rules at the time, so we publish no fixed figure. We tell you the authority’s own published window on the day you ask, plus the steps that usually cause delay.
Our team can review documents and coordinate translation, signature certification, legalisation and embassy steps within the agreed scope. Some steps may still require the document owner to appear or sign in person under the receiving authority’s rules.
We do not publish fixed prices: official fees, page counts and language pairs differ in every case. Send the document details and destination and we will scope the work and cost for your specific case.
Documents can travel by trackable EMS or private courier. Confirm the recipient, address and original-document handling before dispatch; the coordinating destination is Khon Kaen Branch.
Send the document details and the destination that will receive it. We map the correct chain before starting, flag what usually gets rejected, and run it end to end — as advisers, not just a filing agent.
