The Indonesian rules below are stated in general terms and are current as at the date published.
An Indonesian family business usually passes to the next generation by inheritance rather than by sale. Indonesian law decides how that happens, and it does not leave the answer to a will. A single death can split one company among a surviving spouse and several children, each owning a share and none able to act alone. So the first question for a family is how the business passes on intact. The second is whether to keep the family’s capital offshore, as many families have, or bring it home as Indonesia builds a route back.
This guide starts with what a family office is, then works through the succession law that names the heirs, the marriage law that fixes what a founder owns, and the structures that carry a business to the next generation. It weighs the offshore option against the onshore one, and ends on the governance that keeps a family together once the arrangements are in place.
What a family office is, in brief
A family office is a private arrangement that runs a wealthy family’s financial and personal affairs in one coordinated place. It looks after the investments, the tax, the succession, and often the philanthropy and the reporting, across the generations. It takes three forms: a dedicated team serving one family, a shared office serving several families, and a function built inside a business the family already owns. Our guide to the family office sets out the forms and the costs in full. In Indonesia the built-in form is the norm: most families run the office inside a group company or a foundation, a yayasan, rather than a separately staffed office. Whether the wealth inside that arrangement survives a generation depends on Indonesian succession law, which decides who inherits whatever form the office takes.
The succession problem: why a will is not enough
Indonesian inheritance law is plural, and which regime applies depends on the person who died, on their religion and their legal status. Three systems run in parallel, each with its own court.
| Regime | Who it applies to | Court | Forced heirship |
|---|---|---|---|
| Civil Code (Kitab Undang-Undang Hukum Perdata) | Chinese-Indonesian families and others historically subject to the Civil Code, and non-Muslims who submit to the civil system | District Court (Pengadilan Negeri) | Yes, the reserved portion (legitieme portie) |
| Islamic inheritance (faraid), through the Compilation of Islamic Law (Kompilasi Hukum Islam) | Muslim Indonesians | Religious Court (Pengadilan Agama) | Yes, fixed shares and a one-third limit on bequests |
| Customary (adat) law | Communities following local custom, including many indigenous non-Muslim families, by region and lineage | District Court (Pengadilan Negeri) | Varies by custom |
Which regime applies is not always obvious. A Chinese-Indonesian family, a mixed-faith marriage, a conversion, or a blended family can fall under a regime the family does not expect, and the applicable regime can itself be contested between heirs, which a review settles before anything else is decided.
Forced heirship reaches non-Muslim families as well as Muslim ones. The Civil Code reserves a portion of a non-Muslim estate for close heirs, independently of any religious rule, and Islamic inheritance sets fixed shares for a Muslim estate. A family that treats a will as decisive is exposed under either regime.
What a founder actually owns: marriage and the business
Marriage determines what a founder owns, and that in turn fixes what passes on a death. Under Article 35 of the Marriage Law (Law 1 of 1974), property acquired during a marriage is joint marital property (harta bersama), owned equally by both spouses whoever earned it. Property brought into the marriage, and anything received during it by gift or inheritance, stays separate property (harta bawaan) under that spouse’s own control.
A family business built during the marriage is therefore presumptively joint. On a divorce, an ex-spouse can claim half the shares and become a co-owner of the company, with the voting rights and access to the accounts that a co-owner has. On a death, the deceased spouse’s half passes into the estate, where it divides among the heirs. A marital-property agreement (perjanjian perkawinan) can change the default and keep the business separate, so a divorce or a spouse’s estate cannot claim a share of it. Historically such an agreement had to be signed before or at the marriage. Since Constitutional Court Decision No. 69/PUU-XIII/2015, pronounced in 2016, it can be made or amended during the marriage, which opens the option to couples who did not sign one at the start. The marital regime and the corporate structure therefore have to be designed together.
Forced heirship: what a will cannot override
Under the Civil Code, the reserved portion (legitieme portie) is the part of an estate that heirs in the direct line, the children and grandchildren, or the parents where there are no children, are entitled to and that the deceased cannot give away by gift or by will. Articles 913 and 914 set it. The reserved portion is a proportion of the share an heir would take on intestacy, that is, if there were no will at all, rather than a proportion of the whole estate. A single child’s reserved portion is one half of that intestacy share, two children take two-thirds each, and three or more children take three-quarters each. A surviving spouse takes no reserved portion under the Civil Code, though the spouse first keeps a half of the joint marital property before the estate is worked out.
Under Islamic inheritance, the heirs take fixed shares set by the Compilation of Islamic Law. Among children, a son takes twice the share of a daughter. A surviving spouse takes a fixed share as well: a widow takes one-eighth of the estate where there are children and one-quarter where there are none, and a widower takes one-quarter or one-half on the same basis. A bequest by will (wasiat) can go to someone who is not an heir, up to one-third of the estate. To add to one heir’s fixed share by will requires the agreement of all the other heirs, so a parent cannot quietly favour one child over the others.
A will operates within these limits under either regime, so on its own it cannot pass the business to the people a founder intends. Ownership and control are arranged in the founder’s lifetime instead, by moving the business into a company, agreeing in advance through a shareholders’ agreement how the shares are owned and voted, and making lifetime gifts, so that on death the outcome is already fixed rather than left to the inheritance rules to decide.
A worked example: one death, four owners
Take a founder with a spouse and three children and a company, a PT, worth IDR 100 billion, built during the marriage. The figures are illustrative and follow the Civil Code.
| Step | Result |
|---|---|
| Company built during the marriage | IDR 100 billion |
| Surviving spouse keeps a half of the joint property | IDR 50 billion, outside the estate |
| The founder’s half forms the estate | IDR 50 billion |
| Estate shared equally by the spouse and three children | IDR 12.5 billion each |
| New owners of the company | the surviving spouse and the three children, four in all |
The surviving spouse keeps a half of the joint property, IDR 50 billion, which never enters the estate. The founder’s half, IDR 50 billion, becomes the estate, and the spouse and the three children inherit it in equal shares of IDR 12.5 billion. A will cannot escape this, because three-quarters of each child’s IDR 12.5 billion share is reserved and cannot be given away. The company that had one owner now has four, the surviving spouse and the three children, and none can act alone. Without a shareholders’ agreement or a buy-out price agreed in advance, the business can deadlock or be forced to a sale. Under Islamic inheritance the shares differ, a widow taking one-eighth or a widower one-quarter, and a son twice a daughter, and the fragmentation of ownership is the same.
The structures Indonesian law provides
Indonesian law gives a family several structures to pass a business on whole.
| Structure | What it does | Limit |
|---|---|---|
| Domestic company, a Perseroan Terbatas (PT) | Converts a business into shares, so the family passes and gifts shares rather than fragmented assets, and can separate control from value through share classes, where some shares carry votes and others only a right to profit | Needs disciplined records and a clean share register, the official record of who owns the shares, to be worth passing on |
| Shareholders’ agreement | Locks in family control through transfer restrictions, pre-emption rights (the family’s first refusal before any share is sold to an outsider), reserved decisions (the items that cannot change without agreed approval), and buy-out and succession mechanics | Contractual; it works alongside the company’s articles, its registered governing rules |
| Foundation, a yayasan | Serves philanthropy and can act as the controlling owner above the family’s companies | Has no members and no owners and cannot distribute to the family, so it does not transfer wealth to individuals |
| Offshore trust, used with the above | Provides the settlor-and-beneficiary structure, the person who places assets in and the family members who benefit, that Indonesian law does not offer at home | Governed outside Indonesia and brings the owner’s cross-border tax and reporting into play |
Indonesia offers no private family trust. A family that wants a trust uses an offshore one, paired with a domestic PT and, where it fits, a yayasan. The 2023 Financial Sector Development and Strengthening Law (Law 4 of 2023, the P2SK Law) introduced a commercial trustee regime under Article 34, supervised by the Financial Services Authority (Otoritas Jasa Keuangan, OJK). That regime is built for commercial and financial-sector use, needs a licensed institutional trustee, and does not replace a private family trust or override the forced-heirship and marital-property rules above.
Onshore or offshore: the decision a family now faces
Indonesian families have long kept wealth and family offices offshore, chiefly in Singapore, for the tax treatment, the settled legal framework, the banking, and the privacy. The scale shows in the tax-amnesty record. A tax amnesty is a government scheme that lets taxpayers declare previously undeclared assets, many of them based abroad, on favourable terms, in the hope that the money is then brought home, or repatriated. The figures below come from the Directorate General of Taxes.
- The 2016 Tax Amnesty drew IDR 4,854 trillion (around USD 365 billion at 2016 rates) in declared assets, of which IDR 1,031 trillion (around USD 78 billion) was based abroad.
- Of that offshore total, only IDR 147 trillion (around USD 11 billion) was repatriated to Indonesia.
- The 2022 Voluntary Disclosure Programme drew IDR 594 trillion (around USD 41 billion at 2022 rates) in total declarations, with IDR 14 trillion (around USD 1 billion) repatriated.
- Both programmes drew large declarations and returned only a fraction of the offshore assets, which is the gap the current initiative is trying to close.
The government is now courting that capital to return. The National Economic Council initiative, linked to the new Indonesia International Financial Centre in Bali, cites an aspiration of up to USD 500 billion, with Danantara, the state-owned investment fund, positioned to put the returning capital to work. A third tax amnesty remains in the legislative programme, though the sitting Finance Minister has ruled it out. A zero-tax incentive for bringing capital home has been proposed and is not yet enacted. The financial centre permits family offices without distinguishing Indonesian nationals from foreigners, though its rates and qualifying tests are set by implementing regulations, the detailed rules that put the law into effect, which have not yet issued. For now, a family structures for the law as it stands and stays ready to move when the incentives issue.
Governance and the next generation
An office exists to solve the human problems of wealth as much as the financial ones. A family constitution and a family council set how decisions are made and how disputes are settled among a growing number of relatives. The constitution can pre-agree the price and the mechanism for buying out an heir, so the company does not deadlock when ownership fragments on a death, as it did in the example above. Succession planning moves both the assets and the responsibility across the generations, and prepares the next generation through involvement rather than surprise. Philanthropy, often run through a yayasan, gives the family a shared undertaking that keeps it together as it grows. An Indonesian family group commonly passes from a founder to a larger and more dispersed second and third generation, which rewards planning done early.
How TraceWorthy helps
The TraceWorthy team are Indonesian lawyers, accountants, tax specialists, and compliance professionals. Indonesian-qualified specialists handle the domestic law: the succession regime that applies, the marital agreements, the PT, and the yayasan. Our founder, Tracy Wilkinson, qualified in Australia with a Bachelor of Commerce in management and marketing psychology and a Master of Applied Anthropology and Participatory Development, and built the team to a standard set against international practice.
We negotiate cross-border deals, advise on cross-border tax, and draft cross-border agreements ourselves, for a family with part of its structure offshore, a base in Singapore or Hong Kong, or tax and treaty questions across two countries. The edge is in the sequencing: we design the marital-property agreement and the corporate structure together, because each decides what the other can protect. We map the succession under the regime that applies, put the agreements in place, build the PT and the shareholders’ agreement, and use a yayasan for philanthropy or control where it fits. Where an offshore trust or hub belongs in the design, we build the onshore parts and work with locally licensed advisers in that jurisdiction.
One accountable team covers the legal, tax, accounting, and compliance work, so a family is not stitching separate firms together.
The first step is a succession and structure review, taken before any company or agreement is put in place, that reads the inheritance regime the family falls under and the marital position of each owner, so the plan is built on the law that will govern it.

Frequently Asked Questions
Does a will decide who inherits a family business in Indonesia?
Not on its own. Indonesian inheritance law reserves fixed shares for close heirs that a will cannot override, through the Civil Code reserved portion for non-Muslim families and the fixed shares of Islamic inheritance for Muslim families. A will operates within those limits, so a founder arranges the ownership and control of the business during their lifetime, through the company and a shareholders’ agreement, rather than relying on the will alone.
Is forced heirship only for Muslim families in Indonesia?
No. Islamic inheritance sets fixed shares for Muslim families, and the Civil Code imposes its own reserved portion on non-Muslim families, independently. Both regimes limit how much of an estate a person may direct away from close heirs, so a non-Muslim family is protected by forced heirship as well.
What happens to a family business on divorce under Indonesian marital-property law?
A business built during the marriage is presumptively joint marital property, owned equally, so on a divorce an ex-spouse can claim half the shares and become a co-owner of the company, with the voting and information rights that carries. A marital-property agreement can change that default and ring-fence the business, and since Constitutional Court Decision No. 69/PUU-XIII/2015, pronounced in 2016, such an agreement can be entered during the marriage as well as before it.
Can an Indonesian family use a trust to pass on wealth?
Not through a domestic Indonesian trust, because Indonesian law does not provide a private common-law trust. The 2023 commercial trustee regime is built for financial-sector use, needs a licensed trustee, and does not replace a family trust. Families that want a trust use an offshore one, paired with a domestic company and, where it fits, a foundation.
What is a yayasan, and can it own family wealth?
A yayasan is a foundation for social, religious, or humanitarian purposes. It can own assets and can act as a control apex above the family’s companies, though it has no owners and cannot distribute to the family. It suits philanthropy and long-term control, rather than passing wealth to individuals.
Should an Indonesian family keep its family office in Singapore or bring it onshore?
It depends on the family’s tax residence, its banking and privacy needs, and its tolerance for a regime still being written. Many families have used Singapore for its settled framework, and Indonesia is now building an onshore route through its financial centre. Because the onshoring incentives are still pending, a family designs for the current law and stays ready to move as the rules issue.
