🇮🇩 Thai Law vs Indonesian Law: Key Differences
Comparing Thai and Indonesian legal systems — relevant for Indonesian nationals visiting, working, or investing in Thailand.
Indonesia uses a civil law system rooted in the Dutch colonial-era code (KUHPerdata / Burgerlijk Wetboek), with Pancasila as the state ideology and Islamic family law (Kompilasi Hukum Islam) applying to Muslims through Religious Courts. Thailand uses a uniform civil law system with no religious personal-status courts. Both are ASEAN members.
Comparison Table
| Area | 🇹🇭 Thai Law | 🇮🇩 Indonesia | Key Difference |
|---|---|---|---|
| Legal System | Civil law (codified). Unitary system. No religious personal-status courts. | Civil law (Dutch-derived KUHPerdata). Pancasila state ideology. Religious Courts apply Islamic family law to Muslims. | Indonesia has parallel Religious Courts (Pengadilan Agama) for Muslim family matters; Thailand has only secular courts (except limited Sharia provincial courts in the Deep South for Thai Muslims). |
| Marriage / Same-Sex Rights | Marriage Equality Act B.E. 2567 (2024) effective 22 January 2025 — full marriage equality. | Marriage Law 1974 + 2019 amendments. Same-sex marriage not recognized. Religious validity required. | Indonesian nationals can marry same-sex Thai partners in Thailand, but such marriages are not recognized in Indonesia. |
| Visa Status with Thailand | Indonesia is on the 93-country visa-exempt list — 60 days visa-free entry from 15 July 2024. | Thai nationals enjoy 30-day visa-free entry to Indonesia (ASEAN reciprocity). | ASEAN bilateral arrangements plus Thailand's expanded visa exemption make travel between the two countries straightforward. |
| Drug Laws | Cannabis decriminalized 2022 but recreational use restricted since 2024. Hard drugs: death penalty possible. Methamphetamine harshly punished. | Narcotics Law 2009 — death penalty for trafficking. Strict enforcement. Cannabis fully illegal. | Both countries impose the death penalty for drug trafficking; Indonesia actively executes drug offenders, while Thailand has a moratorium since 2018 for most offences. |
| Defamation Law | Criminal offence under Criminal Code Sections 326-333. Truth not always a defence. Imprisonment up to 2 years. | Criminal defamation under KUHP + UU ITE (electronic information law) for online speech. | Both criminalise defamation; Indonesia's UU ITE has been used aggressively against online critics, similar to Thailand's Computer Crime Act. |
| Property / Land Ownership | Foreigners cannot own land. Condos limited to 49% foreign quota. | Foreigners cannot own land freehold (Hak Milik). May hold Hak Pakai (Right of Use) for residential property. | Both prohibit foreign freehold land ownership — Indonesia's Hak Pakai is somewhat analogous to Thai 30-year leases. |
| Tax | Territorial historically — worldwide remittance basis from 2024. Tax resident at 180+ days. Top rate 35%. | Worldwide taxation for residents (183+ days). Top rate 35%. DTA with Thailand in force. | Indonesia-Thailand DTA prevents double taxation on most income; consult a cross-border tax adviser. |
| Family Law | Community property default. Civil marriage at Amphur (อำเภอ). Prenups must be registered with the marriage. | Marriage Law 1974: civil + religious validity required. Muslim family matters governed by Kompilasi Hukum Islam in Religious Courts. | Indonesian marriages require religious solemnisation; Thai marriages are purely civil at the Amphur. |
