How people use this

Three concrete examples.

01

A foreign investor before signing a JV

Checks Foreign Business Act List Three to confirm the target activity isn’t restricted, then reads the Supreme Court rulings on nominee structures before agreeing on capital terms.

02

An expat family handling an inheritance

Reads Book 5 of the Civil and Commercial Code on succession side-by-side in Thai and English, then asks the AI assistant whether a will drafted abroad is enforceable in Thailand.

03

A lawyer doing diligence on a condo block

Uses the Land Code annotated edition to verify the 49% foreign-ownership cap on the building, and pulls the relevant Dika decisions from the curated Supreme Court collection.
