🇸🇦 Thai Law vs Saudi Arabian Law: Key Differences
Comparing Thai and Saudi Arabian legal systems — relevant for Saudi nationals visiting, investing, or seeking medical care in Thailand.
Saudi Arabia's legal system is grounded in Sharia (Islamic law) as the primary source, supplemented by royal decrees (nizam) for commercial and administrative matters. The 2021 Personal Status Law codifies family law for the first time. Thailand uses a unitary secular civil law system with no religious personal-status framework (with limited exceptions for Thai Muslims in the Deep South).
Comparison Table
| Area | 🇹🇭 Thai Law | 🇸🇦 Saudi Arabia | Key Difference |
|---|---|---|---|
| Legal System | Civil law (codified). Unitary system. Secular courts. | Sharia (primary source) + royal decrees (nizam) for commercial matters. Personal Status Law 2021 codifies family law. | Saudi Arabia is one of the world's few jurisdictions where Sharia is the primary legal source; Thailand is fully secular. |
| Marriage / Same-Sex Rights | Marriage Equality Act B.E. 2567 (2024) effective 22 January 2025 — full marriage equality. | Same-sex relations criminalised under Sharia interpretations — severe penalties including imprisonment and corporal punishment. Death penalty possible historically. | Saudi same-sex couples face the most severe legal consequences globally; marriage in Thailand is possible but creates serious risks on return to Saudi Arabia. |
| Visa Status with Thailand | Saudi Arabia is on the 93-country visa-exempt list — 60 days visa-free entry from 15 July 2024. | Thai nationals can obtain Saudi e-Visa. | Saudi nationals enjoy 60-day visa-free entry to Thailand following the 2022 restoration of diplomatic ties and the 2024 visa expansion. |
| Drug Laws | Cannabis decriminalised 2022 but recreational use restricted since 2024. Death penalty possible for trafficking. | Sharia-based prohibition on intoxicants. Death penalty for trafficking — actively enforced (one of the most aggressive globally). | Both impose the death penalty for trafficking; Saudi Arabia actively executes drug offenders, while Thailand has a de facto moratorium since 2018. Thai cannabis decriminalisation has no relevance to Saudi law. |
| Defamation Law | Criminal offence under Criminal Code Sections 326-333 + Computer Crime Act for online speech. | Anti-Cybercrime Law 2007 + Counter-Terrorism Law. Criminal defamation, blasphemy, and lèse-majesté-style offences (insulting King/Royal Family) carry severe penalties. | Both criminalise defamation and protect heads of state; Saudi penalties for online speech and religious offences are among the most severe globally. |
| Property / Land Ownership | Foreigners cannot own land. Condos limited to 49% foreign quota. | Foreigners (non-GCC) generally cannot own real estate except in designated investment zones and with Premium Residency visa. GCC nationals have broader rights. | Both restrict foreign land ownership; Saudi rules are tighter overall but more open in designated investment zones. |
| Tax | Worldwide remittance basis from 2024. Tax resident at 180+ days. Top rate 35%. | No personal income tax. 20% corporate tax for foreign-owned companies. Zakat for Saudi/GCC nationals (2.5%). 15% VAT. No DTA with Thailand in force. | Saudi Arabia has no personal income tax; Thai tax residents face full Thai tax on remitted worldwide income. No DTA — consult a cross-border specialist. |
| Family Law | Community property default. Civil marriage at Amphur (อำเภอ). Prenups must be registered with marriage. | Personal Status Law 2021 codifying Sharia. Polygamy permitted for Muslim men (up to four wives). Sharia inheritance shares apply. | Thailand uses secular community property; Saudi Arabia applies Sharia personal status, recently codified in 2021. |
Important Notes
Saudi nationals enjoy 60-day visa-free entry from 15 July 2024 following the 2022 diplomatic restoration
No Saudi-Thailand DTA in force — but Saudi Arabia has no personal income tax, so practical double-taxation risk is low for individuals
Halal certification and Islamic finance matters in Thailand are handled by the Central Islamic Council of Thailand (สำนักงานคณะกรรมการกลางอิสลามแห่งประเทศไทย)
Saudi nationals are a major medical-tourism source market — premium Bangkok hospitals cater extensively to GCC patients and provide Arabic-language support
