I understand why people have mixed feelings about prenuptial agreements. The word “prenup” can sound cold, suspicious, or even unromantic. You are preparing to marry someone you love, and then a lawyer asks you to discuss divorce, debt, property, and inheritance. Not exactly the candlelit dinner most couples imagined.
Still, I would not treat a prenup as a declaration of distrust. In Indonesia, a well-drafted prenuptial agreement can be a practical way to protect both spouses, especially when the marriage involves different nationalities, children from earlier relationships, businesses, or valuable Indonesian property.
So should you love or hate prenups in Indonesia? My honest answer is: love the idea, but do not sign one blindly.
What Is a Prenuptial Agreement?
Under Indonesian law, a prenuptial agreement is generally called a perjanjian perkawinan. It is an agreement made by prospective spouses to regulate the legal and financial consequences of their marriage.
The agreement can address property ownership, debts, business interests, financial responsibilities, inheritance planning, and other matters connected to the marriage. It is not supposed to control every personal aspect of married life. A clause attempting to regulate matters unrelated to property or legal marital rights may be challenged if it violates law, religion, morality, or public order.
The main purpose is to avoid uncertainty. Without an agreement, Indonesian law generally applies a default marital-property regime. That default may be acceptable for some couples, but it may be a poor fit for others.
The 1974 Marriage Law and Marital Property
Law No. 1 of 1974 on Marriage remains the central legal foundation, although it has been amended, including by Law No. 16 of 2019.
Article 35 divides property into two (2) broad categories. Property acquired during marriage is generally treated as joint marital property. Property brought into the marriage, or received individually as a gift or inheritance, is generally controlled by the spouse who owns or receives it, unless the spouses agree otherwise.
Article 36 provides that actions involving joint property generally require the consent of both spouses. Each spouse may generally control property belonging to that spouse individually.
Article 37 provides that the division of marital property after divorce is determined according to the relevant law, including religious law, customary law, or other applicable rules.
These provisions may sound straightforward, but real life is not. What counts as property acquired during marriage? What happens when one spouse uses inherited money to buy a house? What if a business started before marriage grows substantially during the marriage? What if a bank account contains both separate and joint funds?
A prenup can answer those questions before the family is dealing with conflict.
Article 29: The Legal Basis for the Agreement
Article 29 of the Marriage Law recognizes marriage agreements. The agreement must be made in writing and should not violate religious principles, law, or public morality. It must also be recorded or approved through the legally recognized process.
The Constitutional Court later changed the practical meaning of Article 29 through Decision No. 69/PUU-XIII/2015. Before that decision, the usual understanding was that the agreement had to be made before or at the time of marriage. The Court expanded the rule, allowing spouses to enter into an agreement before marriage, at the time of marriage, or during the marriage.
That decision is especially important for couples who did not sign a prenup before the wedding. A postnuptial agreement is now possible, although the drafting and registration process can still be complicated.
For a couple planning to marry, however, a prenup remains the cleaner option. It establishes the property regime before the marriage begins and avoids disputes about what happened between the wedding date and the date of a later postnup.
Why Prenups Matter in Mixed Marriages
A prenup can be particularly important where one spouse is Indonesian and the other is a foreign national.
The 1960 Agrarian Law, or Law No. 5 of 1960 on Basic Agrarian Regulations, limits the ownership of certain land rights to Indonesian citizens. Article 21 generally restricts Hak Milik, or ownership rights, to Indonesian citizens, subject to limited statutory exceptions. Article 36 regulates Hak Guna Bangunan, or building-use rights, and also restricts who may hold those rights.
A foreign national generally cannot own Indonesian land under the same ownership rights available to an Indonesian citizen. The issue becomes more complicated when the foreign national is married to an Indonesian citizen.
Why? Because property acquired during marriage may be treated as joint property. If the Indonesian spouse buys land during the marriage without a valid separation-of-property agreement, the authorities may question whether the foreign spouse has an indirect marital interest in that property.
A properly prepared prenup can establish that the Indonesian spouse’s property remains separate. This can help preserve the Indonesian citizen’s ability to hold land rights that are legally unavailable to the foreign spouse.
But let me be clear: a prenup is not a magic trick. It does not allow a foreigner to own restricted land. It cannot be used to create a nominee arrangement. It cannot hide the real beneficial owner of property. The transaction must still comply with the Agrarian Law and other land regulations.
The Constitutional Court’s Important Contribution
Constitutional Court Decision No. 69/PUU-XIII/2015 came from a case involving an Indonesian citizen married to a foreign national and the effect of marital property rules on land ownership.
The Court recognized that the old interpretation of Article 29 could unfairly limit an Indonesian citizen’s constitutional property rights. It therefore allowed marriage agreements to be made during the marriage as well as before it.
The decision also emphasized that a marriage agreement can affect third parties. In other words, the agreement may matter not only to the husband and wife but also to creditors, banks, buyers, business partners, and government agencies.
That is why registration matters. A private agreement sitting in a desk drawer may not provide the protection you expect. The agreement should be made in the correct form and recorded with the relevant marriage-registration authority.
For couples who have already married without a prenup, the Constitutional Court’s ruling provides a valuable second chance. But I would still prefer a prenup whenever possible. It is much easier to agree on the rules before financial entanglements become complicated.
What the Islamic Compilation Law Adds
For Muslim couples, the Compilation of Islamic Law, or KHI, is also relevant. The KHI was disseminated through Presidential Instruction No. 1 of 1991 and is used as a material legal reference in the Religious Courts.
Articles 45 through 52 of the KHI deal with marriage agreements. Article 45 recognizes agreements in the form of taklik talak and other agreements that do not contradict Islamic law. Article 47 allows spouses to make an agreement concerning the position of property in the marriage, including the separation or combination of property, provided the agreement does not violate Islamic principles.
The KHI also recognizes joint marital property, known as harta bersama. Articles 85 onward address property acquired during marriage, while Article 97 traditionally provides that each spouse receives half of the joint property after divorce, unless another arrangement applies.
A prenup can therefore be consistent with the KHI, provided the terms are lawful and do not undermine mandatory religious rules. It can identify each spouse’s separate assets, explain how future property will be treated, and reduce uncertainty if the marriage ends through divorce or death.
There is an important practical issue, though. The KHI’s original framework was developed before the Constitutional Court recognized postnuptial agreements during the marriage. This can create administrative uncertainty for Muslim couples seeking to make an agreement after the wedding. A prenup made before marriage is usually easier to process because it fits more comfortably within the traditional framework.
Is a Prenup Unfair?
Some people dislike prenups because they believe the agreement shows that one spouse is planning for divorce. I understand that reaction, but I think it misses the point.
A prenup does not cause divorce. Poor drafting, unfair bargaining, incomplete disclosure, and pressure can create problems, but discussing financial expectations does not destroy a healthy marriage.
The unfair prenup is the one that one spouse signs without understanding, without financial disclosure, or without independent legal advice from lawyer like Wijaya & Co. A contract that gives one spouse everything and leaves the other with no meaningful protection may later be challenged.
Both spouses should understand what they are signing. Each should disclose significant assets and debts. Each should have enough time to review the terms.
The agreement should also be written in language both spouses understand. If one spouse is more comfortable in Indonesian and the other in English, the document should be prepared or translated properly. A language barrier is not a minor technicality when the agreement may affect a home, business, inheritance, or retirement savings.
What Should a Good Prenup Cover?
A useful prenup should be specific rather than dramatic. It may cover property owned before marriage, future income, bank accounts, business ownership, debts, investments, gifts, inheritances, and real estate.
For a mixed marriage, it should address Indonesian land restrictions and make clear that the agreement is not intended to circumvent the Agrarian Law. If either spouse owns a business, the agreement should explain whether the business and its growth remain separate or become partly joint.
The agreement should also address what happens if one spouse dies. A prenup is not the same as a will, and it cannot replace estate planning. If you want a stepchild, child, or other person to receive property, you may need a valid will, gift, or other lawful arrangement.
A prenup should also be reviewed alongside tax, immigration, business, and inheritance planning. A document that solves one problem while creating three others is not good legal planning.
My Final View
I do not hate prenups in Indonesia. I hate bad prenups, rushed prenups, secret prenups, and one-sided prenups.
A fair agreement can protect both spouses. It can preserve the Indonesian spouse’s property rights, clarify responsibility for debts, protect a family business, reduce disputes over inherited assets, and give both people a clearer understanding of their financial future.
The legal foundation is strong enough to make prenups worthwhile. The 1974 Marriage Law recognizes marriage agreements and marital property rules. The KHI provides an Islamic framework for agreements and joint property. The 1960 Agrarian Law explains why property separation is especially important in mixed marriages. Constitutional Court Decision No. 69/PUU-XIII/2015 makes the system more flexible by allowing agreements during the marriage.
So, love or hate? I would choose love the protection, question the wording. Discuss the agreement honestly, prepare it with qualified Indonesian legal professionals like Wijaya & Co, obtain independent advice, and complete the registration process. Romance and legal planning are not enemies. In fact, the right prenup can help you spend less time fighting about money and more time building the life you actually got married to enjoy.
