🇦🇷 Thai Law vs Argentine Law: Key Differences
Comparing Thai and Argentine legal systems — relevant for Argentine nationals visiting, studying, or doing business in Thailand.
Argentina uses a civil law system based on the Código Civil y Comercial of 2015 (unified civil and commercial code), replacing the 1869 Vélez Sarsfield code. The 1853/1994 Constitution provides a federal framework with 23 provinces and CABA. Thailand uses a unitary civil law system.
