Can I Inherit from My Cohabitating Life Partner If They Die Without a Valid Will in South Africa?

No. If your cohabiting life partner dies without a valid will in South Africa, you inherit nothing under the Intestate Succession Act 81 of 1987. The Act distributes a deceased estate to legal spouses, blood relatives and, in limited cases, adopted family. A life partner, however long the relationship, is not on that list.

South African law does not recognise common-law marriage, no matter how many years a couple lived together. Unless you married, registered a civil union, or are covered by a recent court ruling on permanent life partnerships, the estate passes you by entirely.

This guide explains who does inherit, the court challenges that are slowly changing the position, the claims a surviving partner can still bring, and how to protect yourself now.

Who Inherits Under the Intestate Succession Act

When there is no valid will, the estate is distributed in a fixed order of priority. The table shows where a cohabiting partner stands, which is nowhere.

Order of priority	Heir	Share
1	Surviving legal spouse and descendants	Spouse takes a child’s share or a fixed minimum, descendants take the rest
2	Descendants only	Equal shares per stirpes
3	Surviving legal spouse only	Whole estate
4	Parents	Equal shares, or their descendants
5	Siblings	Equal shares
6	Next of kin by blood	Closest degree wins
7	State	Estate escheats if no blood relatives are found

A cohabiting partner appears in none of these categories. The practical result is harsh: a partner of thirty years can watch the entire estate, including the shared home, pass to a distant cousin while they are left with nothing.

The Court Decisions Changing the Position

The courts have begun recognising permanent life partnerships in specific contexts. In Paixao v Road Accident Fund, the Gqeberha High Court read the word “spouse” to include partners in a permanent opposite-sex life partnership, and the Constitutional Court declined to reopen that ruling. The effect was that a surviving life partner could claim like a spouse in that case.

Treat this as developing law, not settled protection. The rulings turned on proof that the partnership was permanent, that the partners shared a duty of support, and that both knew the unmarried partner would not inherit. Nothing in these judgments replaces a valid will as the safe, cheap and certain route.

Claims a Surviving Partner Can Still Bring

Even without inheritance rights, a surviving partner is not always without remedies. Three routes exist, each dependent on facts and evidence:

• Universal partnership claim. If the couple ran their financial lives as a partnership, with a contribution, a joint enterprise, and profit sharing, the surviving partner can claim a share of partnership assets from the estate. The evidentiary bar is high.
• Contractual claims. A cohabitation agreement, joint ownership of property, or a beneficial interest the deceased acknowledged in writing can support a claim against the estate.
• Life-partnership equality claims. Where the partnership was permanent with a shared duty of support, constitutional arguments based on the developing case law may be open, but litigation is costly and the outcome uncertain.

These claims are lodged against the estate through the executor, with the Master’s Office supervising. They do not happen automatically; someone must assert them.

How to Protect Your Position Now

1. Execute valid wills. Each partner signs a will leaving assets to the other. Review the wills after children, property purchases or separation.
2. Sign a cohabitation agreement. Record who owns what, how household expenses are shared, and what happens on death or separation.
3. Put assets in both names where intended. Joint ownership with right of survivorship passes outside the estate and beats an intestate scramble.
4. Keep financial records. Proof of shared expenses, contributions to property and joint accounts supports a universal partnership claim if the worst happens.
5. Name the partner on policies and pensions. Beneficiary nominations on life policies and retirement funds fall outside the estate.

Common Mistakes to Avoid

• Believing in common-law marriage. It does not exist in South Africa. Years of cohabitation create no automatic inheritance rights.
• Relying on the deceased’s verbal promises. “She said the house is mine” is not a will. Only a valid written will, properly executed and witnessed, counts.
• Assuming engagement changes anything. A promise to marry creates no inheritance rights until the marriage is concluded.
• Delaying claims against the estate. An estate is wound up on a timetable; a claim lodged after the liquidation and distribution account has been finalised may be too late.
• Ignoring the antenuptial trap. Even a spouse married out of community of property without accrual inherits, but check what the will says. Cohabiting partners have no such floor at all.

Frequently Asked Questions

Can I inherit from my cohabiting life partner if they die without a will in South Africa?

No. The Intestate Succession Act 81 of 1987 gives a deceased estate to legal spouses and blood relatives only. A cohabiting partner inherits nothing unless there is a valid will, a proven universal partnership, or a successful claim under the developing life-partnership case law.

Does South Africa recognise common-law marriage after living together for years?

No. There is no common-law marriage in South African law, however long a couple has lived together. Only a civil marriage, customary marriage or registered civil union creates spousal inheritance and maintenance rights.

What is a universal partnership claim against an estate?

It is a claim by a surviving cohabiting partner that the couple ran their affairs as a partnership, each contributing to a joint enterprise with benefit sharing. If proved, the partner can claim a share of the partnership assets from the deceased estate.

How can cohabiting partners protect each other?

Sign valid wills leaving assets to each other, conclude a cohabitation agreement, register major assets jointly where survivorship is intended, and name each other as beneficiaries on life policies and retirement funds.
