– 2006, Opening

Khun Santi Varit (Thai Attorney), Khun Thavison (President of the Nakhon Ratchasima Chamber of Commerce) and Mr Sebastian H. Brousseau decided to share their experience and build a new business to help expats in the area.

– 2007, New partners and attorneys

Mr Sebastian H. Brousseau became the company’s director and opened a new office on Pho Klang Road. New employees, including full-time Thai lawyers, translators and paralegals started to work for us. It is also in that year that our law firm started to use the name “Isaan Lawyers”.

We moved our office to a brand new location at Times Square, Nakhon Ratchasima. Conveniently located, with ample parking and the offices on the ground floor. We were one of the first law firms from Thailand to it’s own YouTube channel: ThaiLawOnline (2010, in Thai and English). We have helped charity organisations, trained young interns to become lawyers, and believe in building a bright community through social involvement.

David S., South Africa (case in Buriram)
Property, Inheritance, Civil Law.     

"Many thanks to Sebastian and his team from Isaan Lawyers for the excellent service I received from them. Having run the gauntLet of "reputable" lawyers in Thailand and their services (...)  I finally got results (against all the odds) and won my case in spite of not being able to be present in Court for the appropriate date. I was charged an extremely low fee in comparison to what I gained, and indeed: in comparison to what I had already paid in advance to the non to the non performing but ever-promising Thai legal law firm I had previously approached for help. I was treated with dignity and honesty and have no hesitation in recommending this particular law firm to anybody needing help as regards matters Thai. (...) I hereby happily give my permission for them to use me as a contact reference, and for them to supply my email adress to anybody still in doubt as to their competency and integrity."

Richard B., UK (case in Nakhon Ratchasima – July 2011)
Probate of Will.     

"I would like to take this opportunity to thank the team at Issan Lawyers for their handling of probate for my wife's will.  In a very short time I had all the necessary court orders, translations of documents and your assitance getting bank to release funds and change property ownership at land office.  Looking back it was nice having someone to deal with all the legal matters and I now realize I chose the right firm to handle this matter.  I will not be hesitant in selecting Issan Lawyers should I need other legal services in the future."

Trond A., Norway. (Case and work in Udon Thani)
Divorce, Translation and Legalization of Documents.      "Me and my fiancée used Isaan Lawyers to get a divorce for my fiancée cause her former husband abandoned her more than one year before we met. Isaan Lawyers did great work for a reasonable price, and my fianceè got her divorce easy as promised by jugdement in Court of Law. We have also used Isaan Lawyers to get papers from Amphur translated and stamped by the Thai Ministry of Foreign Affairs, papers to be used for application for fiancée visa. We will surely use Isaan Lawyers again when the time requires it, and have no problem to recommend their service."
Keith S., UK. (August 2010)

Dan S., USA. (November 2010)

Prenuptial Agreement Online and others.      "I wanted to write a few words to thank you and your team for helping me and my wife draft and work through a prenuptial agreement prior to our marriage. I must say that your service is what all other companies in Thailand and elsewhere should strive for. Your fellow workers are a delight, so thorough & accurate, the kind of valuable employees that every company needs; you are lucky to have them. I have worked with dozens of law firms in America both business related and personally and without exaggeration your firm's work was equal or better than than I have seen there, and your pricing was definitely the most reasonable. Hopefully I'll get a chance to recommend you firm to someone else, and if given the chance the recommendation will be glowing"

Anders N., Sweden.(March 2011 – work in Phuket)
Real Estate Law - Property Contracts.     

"I was recommended Isaan Lawyers through a fellow countryman who is also a client. My wife and I live in Phuket, where everything is overpriced like there is no tomorrow and with the recommendation from my friend, I wanted to give a law firm from "out of town" a try. I was a little bit hesitant at first, but after dealing with Sebastian and his team, all of that is gone. The support and prep-work beforehand was excellent in everyway and for the first time since long, I have the feeling of not beeing ripped off. I am truly grateful for the services provided and I will return with any future needs I might have. I now consider Isaan Lawyers to be "my lawyer in Thailand" and I feel comfortable of recommending them to anyone."

L., Singapore (October 2014)

Gary B.,(March 2013)

"We were there approximately two hours. They asked us for an extra copy each of my passport and her tabien bahn, which we had. They reviewed the contracts you put together, had us pay 75 Baht and we walked out with my name on the Chanote. Thank you for a job well executed. I will happily recommend your services should the opportunity arise.We also look forward to doing business with you again next year when we move to Thailand, to write up our Thai wills."

Svente K., Sweden (Cha-Am – October 2015)
