Prenuptial Agreements in Indonesia: Why Mixed Marriages Need Them

So, you came to Indonesia for a holiday, fell in love with the endless coconuts, beach walks, and nasi goreng — and then fell in love with someone special. Now you’ve decided to get married. What’s next? 

If you’re planning to marry an Indonesian citizen and invest in land, property, or a business, a prenuptial agreement (perjanjian pranikah) is not just a formality — it is essential for protecting your assets and complying with Indonesian law. 

Can foreigners own property in Indonesia?

Under Indonesian law, foreigners cannot own freehold land (Hak Milik). Instead, investments are typically structured through: 

• PT PMA (foreign-owned company) ownership – the most secure legal route. 

• Leasehold (Hak Sewa) – long-term leases that offer usage rights without ownership. 

• Hak Pakai (Right to Use) – possible but difficult to obtain and subject to strict conditions. 

• Nominee agreements – not legally recognised and highly risky. 

When a foreigner marries an Indonesian citizen, property ownership becomes even more complex — especially without a prenuptial agreement. 

What happens if you marry without a prenuptial agreement?

In a mixed marriage without a prenup, Indonesian law assumes a joint marital property regime. That means any assets acquired during marriage — including land, businesses, and income — are co-owned. 

If your Indonesian spouse holds land or a business in their name, and you don’t have a prenup separating assets, it can: 

• Invalidate their right to own freehold land, as it is considered jointly owned with a foreigner 

• Create legal issues for inheritances, sales, or transfers 

• Complicate your rights in divorce or inheritance scenarios 

What does a prenuptial agreement do?

A legally notarised prenup allows you to establish separate property ownership during the marriage. This ensures: 

• The Indonesian spouse to retain full rights over land or shares 

• The foreign spouse to structure investments through legal channels (e.g., PT PMA) 

• Proper asset planning that complies with Indonesian law 

Can I create a postnuptial agreement?

Since 2015, postnuptial agreements (perjanjian pisah harta setelah menikah) have been allowed. However: 

• They must be approved by a notary. 

• They may not fully resolve ownership issues retroactively. 

• A prenup remains the safest option to prevent future disputes. 

Common mistakes to avoid:

• Skipping the prenup out of trust or discomfort. 

• Signing informal agreements that are not notarised. 

• Making property or business investments before legal agreements are in place. 

These mistakes often lead to costly disputes and even the loss of ownership rights. 

Final thoughts

Love may be simple — but the law is not. 

If you're planning to marry an Indonesian citizen and invest in land or a business, don’t skip the prenup. It’s not about mistrust — it’s about compliance, clarity, and protecting your shared future.
