In Thailand, daily life is regulated in the Civil and Commercial Code, which is published in 6 books: see https://hinproperty.de/thailand-civil-and-commercial-code/. HinProperty has written a series of articles to document Thai property laws and an understandable interpretation by Thai lawyers. (https://thailandlawonline.com).
From our experience there are 4 main topics that expats are interested in:
1. Buying a condominium

2. Purchase and ownership of real estate
• In the HinProperty post https://hinproperty.com/foreign-property-in-thailand/
3. Own a house as an expat
• In the HinProperty post https://hinproperty.com/foreign-home-ownership-separate-from-property/
•4. Lease and Tenancy of Property
• In the HinProperty post https://hinproperty.com/foreign-property-in-thailand/
If you google internet sites you will mostly find interpretations of Thai law mixed with wishful thinking or old experiences overruled by local courts, especially for lease and purchase of real estate in a company name.
