A power of attorney for overseas use normally needs signature certification by a Notarial Services Attorney, followed by legalization and/or embassy attestation.
Clients in Bangkok can walk in at Bangkok Headquarters (Lat Phrao 95).
Bangkok hosts almost every embassy accredited to Thailand, and the Department of Consular Affairs, which legalises documents, sits on Chaeng Watthana Road in Lak Si. Clients in the capital can therefore usually finish all three stages in one city: notarial attestation by a Notarial Services Attorney, translation, and legalisation at the Ministry of Foreign Affairs or the relevant embassy. What slows Bangkok files down is rarely distance; it is appointment queues and cross-town travel at rush hour, so the order in which you visit each office matters more here than elsewhere.
Our head office is on Lat Phrao 95, so documents can be signed in person there. Before any government visit we tell you which steps you must attend yourself and which can be done under a power of attorney, because some embassies insist that the applicant appears in person. Building the plan around those fixed appearances is usually what saves the most time in Bangkok.
Many Bangkok clients use the same document set with several authorities, for example an affidavit of single status at an embassy and then at a district office for marriage registration. Tell us at the start every place the document will be used. We can then prepare enough originals and certified copies in a single round, instead of reopening the file after the first authority keeps the only original. If you are working to an embassy appointment date, send us that date too, so the attestation and translation are finished with a margin before you queue.

The steps below are drawn from the procedures the responsible authority publishes itself, with the source and verification date shown. Some steps depend on the case and may change with the authority’s own announcements. Department of Consular Affairs (MFA) and the Lawyers Council of Thailand · 2026-08-10
The authority’s own form was not used
Bodies such as the Land Department and the DBD prescribe their own forms; a self-drafted document may be refused even when the content is complete.
The stated scope does not cover the act being filed
The officer must see wording that names the act directly; broad or partial delegation leads to a request for a fresh document.
Stamp duty was not affixed
A power of attorney is an instrument requiring stamp duty before use; filing without it usually means the office holds the matter until it is done.
Signed abroad without the full authentication chain
Documents signed overseas need certification by a Thai embassy or consulate and then MFA legalization before they can be used in Thailand.

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 Bangkok Headquarters (Lat Phrao 95).
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.
