Prenuptial Agreements for Mixed Marriages in Bali: Property and Inheritance
Why a prenup matters when marrying an Indonesian: joint property, Hak Milik, Constitutional Court Decision 69/PUU-XIII/2015 postnups, notarisation and registration. Updated November 2026.
Updated November 2026
Short answer: Yes, if you marry an Indonesian and want them to keep or buy freehold (Hak Milik), you need a prenuptial or postnuptial agreement that separates your property. Without it, assets acquired during the marriage are joint property, and because a foreigner cannot hold freehold, the Indonesian spouse can lose the right to hold Hak Milik bought during the marriage. Since Constitutional Court Decision 69/PUU-XIII/2015 the agreement can be made before or during the marriage. It must be made as a notarial deed and registered with the civil registry or KUA.
Key points
- Basis: Marriage Law Article 29, as read by Constitutional Court Decision 69/PUU-XIII/2015.
- Form: notarial deed, registered with the civil registry (non-Muslims) or KUA (Muslims).
- Timing: before the wedding or during the marriage.
- Foreign prenups: may need to be redone or registered in Indonesia to protect Indonesian assets.

Without a prenup, every Indonesian-foreign marriage in Bali automatically pools all assets into joint marital property and freezes the foreign spouse out of every land title. Here is how foreign couples actually protect themselves in 2026.
Under Indonesian Marriage Law No. 1 of 1974 (as amended by Law No. 16 of 2019), any mixed-nationality marriage that does not have a prenuptial agreement falls into the default community-property regime. That means the moment you say “ya,” every asset either spouse owns or buys becomes jointly owned. For a foreign spouse trying to hold land in Bali, this is catastrophic, Indonesian law forbids foreigners from holding freehold land, and joint ownership infects the Indonesian spouse’s title.
What the 2015 Constitutional Court ruling actually unlocked
For decades, Indonesian marriage law only recognised prenups signed before the wedding. The 2015 Constitutional Court ruling (Putusan MK 69/2015) opened the door to postnuptial agreements as well, meaning couples already married can still execute one. The ruling has been embraced by the Ministry of Home Affairs and the Civil Registry (Dukcapil), and the registration process is now routine in Bali.
The catch: a postnup is only enforceable against assets acquired after registration. Assets already in your joint marital pool before you sign stay in it. That makes timing critical, the earlier you register, the more you can protect.
Why every mixed-nationality couple in Bali needs one
Hak Milik (freehold) and Hak Guna Bangunan (right to build) can only be held by Indonesian citizens. If an Indonesian wife buys property in her name during a marriage with no prenup, that property is legally a marital asset jointly owned with her foreign husband. The Agrarian Court has consistently struck down those titles since the 1996 Supreme Court precedent, leaving the Indonesian spouse holding nothing and the foreign spouse with no claim either.
A properly drafted prenup or postnup separates property completely, pisah harta, so each spouse owns what they buy in their own name. The Indonesian spouse can then hold Hak Milik land without the foreign spouse’s interest tainting the title.
What clauses a Bali prenup must contain
A registrable prenup in Bali typically includes complete separation of property (pisah harta murni), separation of debts and liabilities, a clear schedule of pre-marriage assets each spouse brings in, treatment of inherited assets received during the marriage, business income separation, and language confirming the Indonesian spouse retains exclusive ownership over any land titles registered in their name.
The most modern drafts also add a forum-selection clause picking Indonesian courts for any Indonesian-asset disputes, plus optional mediation clauses to avoid the public divorce courts.
What affects the cost
The total depends on the documents you already have, how many parties are involved, the government charges that apply at the time, and how much drafting or follow-up the matter needs. Government charges are set by regulation and change from time to time, so we confirm the current figures in writing before you commit. Contact us for an exact quote.
The four-step Bali prenup process
Step one is the consultation: the lawyer reviews each spouse’s nationality, assets and intended property plans. Step two is the draft, which is bilingual Indonesian and English with the Indonesian version as the controlling text. Step three is the notarial deed, signed in person before a notary with two witnesses. Step four is registration: the deed is submitted to the Civil Registry (Dukcapil) where the marriage is or will be recorded, after which a notation is added to both spouses’ marriage certificate.
For postnups, the timing requirement is strict: registration must happen within 30 days of signing the notarial deed. Miss that window and the agreement loses enforceability for new assets.

Frequently asked questions
Can my Indonesian spouse buy Hak Milik land after we sign a postnup?
Yes. Once the postnup is registered at Dukcapil, your Indonesian spouse may purchase Hak Milik land in her own name, financed and owned exclusively by her. The foreign spouse must not contribute funds directly or the Agrarian Court may treat the title as a nominee structure.
Do I need to sign in Indonesia?
Yes. Both spouses must sign before an Indonesian notary in person. We arrange flexible notarisation in Denpasar, Ubud or Canggu and coordinate with the Dukcapil where your marriage is registered.
Does a foreign prenup signed abroad work in Indonesia?
No. A prenup must be in Indonesian notarial form and registered in the Indonesian Civil Registry to bind Indonesian assets. We can adapt a foreign prenup into a compliant Indonesian deed.
What are the steps to make a prenup in Bali?
- Agree the property terms with independent advice for each partner.
- The notary drafts the deed, with a sworn translator if needed.
- Both sign before the notary.
- Register the agreement with the civil registry or KUA, and note it on the marriage record.
