Intestate Succession Act 81 of 1987: Who Inherits When There Is No Will in South Africa

What Happens When You Die Without a Will in South Africa

Roughly 70% of South Africans die without a valid will, which means their estate gets divided according to a fixed statutory formula rather than their personal wishes. The Intestate Succession Act 81 of 1987 is the law that dictates exactly who inherits what — and the results often surprise grieving families.

The Act creates a strict hierarchy of inheritance. It does not care about promises you made, verbal agreements with family members, or what anyone assumes they are entitled to. The formula is mathematical, and the Master of the High Court applies it mechanically once Letters of Executorship or Letters of Authority are issued.

The Inheritance Hierarchy Under the Act

The Act distributes assets in a specific order depending on which relatives survive the deceased.

Spouse only, no descendants: The surviving spouse inherits the entire estate. For couples married in community of property, the surviving spouse already owns half the joint estate automatically — so they inherit the deceased's remaining half.

Spouse and descendants: The surviving spouse receives R250,000 or a child's share (the estate divided equally among the spouse and all children), whichever is greater. The remaining balance is divided equally among the descendants. If a child predeceased the deceased but left their own children, those grandchildren step into their parent's share through representation.

Descendants only, no spouse: The estate is divided equally among the children. Grandchildren only inherit if their parent predeceased the deceased.

No spouse and no descendants: If both parents survive, they inherit in equal shares. If only one parent survives, that parent takes half and the descendants of the deceased parent take the other half — unless the deceased parent left no descendants, in which case the surviving parent takes the whole estate. If both parents are deceased, the estate passes to the descendants of the parents (typically siblings and their descendants), with the Act's representation rules applying.

No surviving relatives at all: Only in this case does the estate devolve on the state.

How Matrimonial Property Regimes Complicate Intestate Succession

The matrimonial property regime determines what actually forms part of the deceased estate before the Intestate Succession Act kicks in.

In community of property (the default for marriages without an antenuptial contract), the entire joint estate is frozen. All debts are settled from the joint pool first. The surviving spouse receives their automatic 50% share, and only the remaining 50% is distributed under the Act.

Out of community of property with accrual requires a calculation comparing how much each spouse's estate grew during the marriage. The spouse whose estate grew less has a claim against the other's estate for half the difference — and this claim ranks ahead of any intestate distribution.

Out of community of property without accrual means each estate is entirely separate. The deceased's assets alone form the intestate estate.

Customary Marriages and Polygamous Unions

The Reform of Customary Law of Succession and Regulation of Related Matters Act 11 of 2009 brought customary marriages into alignment with the Intestate Succession Act, abolishing the old rule of male primogeniture that gave everything to the eldest son.

In polygamous customary marriages, each surviving spouse is entitled to receive a child's share or R250,000, whichever is greater. The remaining estate is then divided equally among all descendants from all marriages.

A common complication arises when a customary marriage was never registered with the Department of Home Affairs. The Master's Office will not recognise a surviving spouse without a formal marriage certificate — even though the Recognition of Customary Marriages Act says non-registration does not invalidate the marriage. Families facing this situation must either apply for posthumous registration or approach the High Court for a declaratory order.

Unmarried Partners and the Bwanya Precedent

Until recently, unmarried partners in permanent life partnerships had zero inheritance rights if their partner died intestate. The Constitutional Court changed this in Bwanya v Master of the High Court (2021), ruling that the exclusion violated the rights to equality and human dignity.

Parliament formalised this through the Judicial Matters Amendment Act 15 of 2023 (effective 3 April 2024). Surviving permanent life partners can now claim maintenance and inherit from an intestate estate on the same basis as a married spouse — but they bear a heavy burden of proof. They must demonstrate financial interdependency through evidence like joint bank accounts, shared household expenses, and being named as a dependant on a medical aid.

Why Intestacy Creates Practical Problems

The statutory formula sounds clean on paper, but it regularly causes chaos in practice.

Bank account freezes: Banks freeze all accounts in the deceased's name immediately upon notification. For couples in community of property, this includes accounts in the surviving spouse's name too, cutting off access to grocery money, school fees, and electricity payments.

Master's Office delays: The Master of the High Court typically takes several weeks to issue Letters of Executorship. During this period, no one has legal authority to deal with the estate's assets, but funeral arrangements and daily expenses cannot wait.

Family disputes: Without a will nominating specific beneficiaries, arguments about who gets what are settled by the Act's formula — which frequently conflicts with what the family expected. A surviving spouse who assumed they would inherit everything discovers they must share with adult children. A life partner who assumed the relationship was recognised discovers they must prove its existence through documentation they may not have.

Protecting Your Family From Intestate Succession

A valid will under the Wills Act 7 of 1953 generally determines how the property it validly disposes of is distributed; any undisposed residue may still pass under the Intestate Succession Act. You can nominate an executor you trust rather than leaving the appointment to the Master's Office. You can establish a testamentary trust to protect minor children's inheritance from being paid into the state-run Guardian's Fund.

The South Africa End-of-Life Planning Guide walks through the complete will-drafting process, including the specific witness and signature requirements that invalidate roughly one in five self-drafted wills. It also covers how to structure your estate to minimise executor fees, which are calculated at 3.5% of gross assets (not net equity) — a distinction that regularly catches families off guard.

Planning now costs a fraction of what intestacy costs your family later, measured not just in money but in months of bureaucratic delay and family conflict that a clear will would have prevented entirely.
