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

When someone dies without a valid will in South Africa, the state does not simply hand everything to the spouse or the eldest child. Instead, the Intestate Succession Act 81 of 1987 takes over — a rigid statutory framework that distributes the estate according to prescribed rules, regardless of what the deceased may have verbally wanted. If your family is navigating this right now, understanding these rules quickly is essential, because the distribution formula is not what most people expect.

The Basic Distribution Formula

The Act calculates inheritance using the concept of a "child's share", which is the gross estate value divided by the number of people who qualify — specifically, the surviving spouse(s) plus the number of children.

Here is how it works in practice:

No spouse, only children: The estate is divided equally among the children. If a child has predeceased the deceased but left children of their own (grandchildren of the deceased), those grandchildren share their parent's portion equally.

Spouse but no children: The surviving spouse inherits the entire estate.

Spouse and children: This is where the formula matters. The estate is divided by the number of people in the pool — one spouse plus the number of children. Each person receives one child's share. However, the surviving spouse is guaranteed a minimum floor of R250,000 (adjusted by regulation from time to time) if their calculated share falls below that amount.

Example: Estate worth R1.8 million. Surviving spouse plus three children. The pool is four people. Each child's share is R450,000. The spouse receives R450,000; each child receives R450,000. If the estate were only R600,000 — each person's calculated share would be R150,000, which falls below the spouse's minimum floor. In that case, the spouse takes the full R250,000 minimum, and the remaining R350,000 is divided among the three children.

What "Children" Means Under the Act

The Intestate Succession Act was amended in 1988 to remove distinctions between legitimate and illegitimate children. All biological children inherit equally, regardless of whether their parents were married. Adopted children also inherit from their adoptive parents as if born to them.

Importantly, a child's death before the deceased does not cut off that branch of the family tree. Grandchildren step into their deceased parent's share through the principle of per stirpes distribution — they share among themselves what their parent would have received.

Customary Marriages and the Intestate Rules

The Recognition of Customary Marriages Act 120 of 1998 gave full legal recognition to marriages concluded under African customary law. Critically, registration at Home Affairs is not required for the marriage to be valid. A customary marriage is legally valid if both parties were over 18, consented, and the marriage was negotiated and celebrated according to customary law.

This creates real-world complications for intestate estates. When the deceased had both a customary wife and a civil wife — or when the extended family disputes whether lobola negotiations were complete — the Master of the High Court cannot simply decide who is married. The Master will convene a formal family meeting to attempt to establish the facts. If the dispute cannot be resolved informally, it escalates to High Court litigation, which can run for years and consume a substantial portion of the estate in legal fees.

A surviving customary spouse who is not on a marriage certificate must submit evidence to the Master: a lobola letter, photographs of the traditional ceremony, or affidavits from family elders who were present at the negotiations.

Muslim Marriages: The Daniels and Hassam Constitutional Court Rulings

For many years, spouses in Muslim marriages had no inheritance rights under the Intestate Succession Act because Islamic marriages were not recognized in South African common law. This was corrected by a series of landmark Constitutional Court decisions, most significantly Daniels v Campbell and Hassam v Jacobs.

The Court ruled that spouses in both monogamous and polygynous Muslim marriages are fully recognized as "spouses" for intestate succession purposes. In a polygynous marriage where the husband dies without a will, the estate is divided equally among the surviving wives and the children — every surviving wife has the same standing as any other spouse under the formula above.

Despite these rulings, application on the ground remains challenging. Home Affairs officials are not always trained to recognize unregistered Islamic marriages, and surviving widows often face resistance from in-laws who dispute the marriage's validity. Having documentary evidence of the Islamic ceremony, witnesses, and any formal records is essential when dealing with the Master's Office.

Unmarried Life Partners: The Bwanya Case Changes Everything

Until 2021, an unmarried partner — regardless of how many years you lived together — had no right to inherit intestate. The law treated cohabiting partners as legal strangers.

The Constitutional Court changed this in Bwanya v Master of the High Court, ruling that excluding surviving permanent life partners from intestate succession was unconstitutional. If you and your partner had undertaken reciprocal duties of support — shared finances, cohabitation, a mutual intention to form a marriage-like union — the surviving partner can now inherit intestate and claim maintenance from the estate.

To establish this to the Master's satisfaction, the surviving partner must submit Form MBU 19: an affidavit confirming the duration of cohabitation, financial interdependence, and the mutual intention of the relationship.

This applies to both heterosexual and same-sex life partnerships.

When Minors Inherit: The Guardian's Fund Problem

If a minor child (under 18) inherits cash through intestate succession and there is no testamentary trust in a will — because there is no will — the executor is legally prohibited from paying that cash directly to the minor or to the surviving parent.

The money must be paid into the Guardian's Fund, administered by the Master of the High Court and invested with the Public Investment Corporation. Accessing these funds for the child's school fees, medical expenses, or clothing requires submitting Form J341, undergoing biometric fingerprint verification, and providing detailed quotations for every expense. The bureaucratic delays in this process are severe and well-documented.

This is one of the most compelling reasons to have a properly drafted will that establishes a testamentary trust for minor children — it keeps their inheritance under private management rather than state administration.

What Happens Next After Intestacy Is Confirmed

Once it is established that there is no valid will, the heirs must formally nominate an executor — known in South African law as an executor dative — by submitting a Nomination Form to the Master. All the major heirs must agree on who this person will be. If they cannot agree, the Master can appoint someone.

Under Chief Master's Directive 9 of 2023, if the nominated executor is a layperson (rather than an attorney or trust company) and the estate exceeds R250,000, the Master requires that layperson to formally appoint a qualified professional agent — such as a registered attorney or chartered accountant — to assist with the administration. The professional agent must confirm their appointment in writing to the Master.

The full estate administration process then follows: reporting the estate, obtaining the Letter of Executorship, opening an "Estate Late" bank account, advertising for creditors, drafting the Liquidation and Distribution account, and obtaining the SARS Deceased Estate Compliance letter before the estate can be closed. For most estates this takes between 9 and 15 months.
