It seeks to publish original articles reflecting high quality research and analysis about the legal system in Thailand, including its laws, institutions, and jurisprudence, as well about legal issues more generally affecting Thailand. For scholarly articles, TLS uses the double-blind method of peer review whereby neither the author nor the reviewers know the identity of the others involved in the process.

In addition, Thai Legal Studies publishes shorter works, such as Opinions or Comments about specific legislation, court decisions, or previously published TLS articles, Current Developments, Book Reviews, and Summaries of articles previously published in Thai. TLS also welcomes the submission of fully translated articles previously published in Thai, the aim being to provide greater worldwide accessibility to Thai scholarship and thought.
