Law Firm in Bangkok

Siam Legal International

Need to find a Bangkok Lawyer in Thailand?

Law Firm in Bangkok

Siam Legal is a full service law firm in Bangkok with offices in other major cities in Thailand such as Pattaya, Chiang Mai, Samui and Phuket.

Bangkok being the Thai capital city is not only the political capital of Thailand but also the heart of its legal fraternity. Bangkok has nine criminal and civil courts and is also the seat of both the Thai Appellate division and the Thai Supreme Court. We at Siam Legal International have our head office in the Sukhumvit area area right next to the BTS Nana Station Exit 2.

With Bangkok being home to Thailand speciality courts such as the Labour Court, Bankruptcy Court and the Intellectual Property Court, having a Bangkok lawyer with offices across Thailand makes perfect sense to any astute client.

Do you need legal services in Bangkok?

If you require the services of a law firm or a Thai lawyer for business registration, Thai immigration or divorce, Bangkok is the location of the head offices of the Ministry of Commerce, Department of Justice, Land Office and most other administration of justice and commercial offices in Thailand.

In Thailand the provincial offices are only branches of the main office in Thailand. This is why having an attorney in Bangkok with multiple branches makes sense. As an example if you wish to register a property in Phuket, the documents still have to come to the Land Office in Bangkok.

Much the same goes for immigration in Thailand. Let's say an application for Permanent Residence is made in Pattaya, it still needs approval by Thai Immigration in Bangkok.

We have highlighted why it is so important in Thailand to make use of a reputable Bangkok law firm with both local and foreign lawyers. This is why most people choose to have a Bangkok lawyer with a Bangkok based law firm who has branch offices in other provinces of Thailand.

As a premier law firm in Bangkok dealing with various legal services, we have licensed Thailand lawyers both Thai and foreign (UK Solicitors & Barristers, German Lawyers, American Attorneys, and Australian Solicitors) and we are experienced in working with and through the government offices in Bangkok. Our lawyers are also licensed to practice throughout Thailand and much of the Western world as we have lawyers and offices in all the important provinces in Thailand outside of Bangkok.
