What Are The Requirements for Cohabitation in South Africa?

Cohabitation in South Africa has no statutory requirements and creates no automatic legal relationship — there is no “common law marriage” and no automatic “universal partnership” that attaches to live-in couples after any period of time. The Constitutional Court addressed the position of unmarried partners in Bwanya v Master of the High Court, Cape Town (CCT 241/20) [2021] ZACC 51, declaring unconstitutional the exclusion of surviving permanent life partners from the Intestate Succession Act. The legal protections cohabitants do have come from separate pieces of legislation: the Domestic Violence Act 116 of 1998 (which qualifies cohabitants for protection orders), the Children’s Act 38 of 2005 (parental responsibilities and rights for parents of children of the relationship), the Maintenance Act 99 of 1998 (child maintenance claims), and any notarial cohabitation agreement the couple chooses to execute. Couples who want enforceable obligations — on property, support, or next-of-kin rights — must put them in writing, because the law does not infer them from living together.

The Short Answer: Cohabitation Has No Legal Requirements

South African law does not recognise cohabitation as creating a marriage or any equivalent status, regardless of the length of the relationship. There are no formalities to enter into cohabitation, no registration step, and no automatic legal duties that arise from it. There is no period of cohabitation after which a couple becomes “married by operation of law,” and no automatic community of property, duty of support, or inheritance right that arises simply from living together. Couples who want enforceable obligations must create them themselves, either by signing a notarial cohabitation agreement or by invoking specific statutory protections designed for unmarried families.

Why There Is No “Common Law Marriage” in South Africa

Unlike some other jurisdictions, South Africa has no equivalent of English common law marriage. Cohabitation does not convert into a marriage after a fixed period, regardless of how long the couple lives together or whether they present themselves publicly as spouses. Two points are frequently misunderstood:

• No “common law marriage” by lapse of time. A couple does not acquire marital status by living together for any length of time. South African courts have consistently rejected the argument that long cohabitation, by itself, generates a marriage.
• “Universal partnership” is not automatic. The universal partnership doctrine requires a commercial or profit-sharing partnership, not a romantic household — it does not attach to every unmarried relationship.

The practical result: cohabitants carry no automatic duty of support to one another, no automatic inheritance on death, and no automatic medical-decision authority for an incapacitated partner.

The Four Legal Layers That Do Apply to Cohabitants

Cohabitation does not by itself create legal duties, but four specific bodies of law do apply to cohabiting couples. Each layer is opt-in or condition-specific — it protects a defined interest rather than the relationship as a whole.

Legal layer	What it does	Who it protects
Cohabitation agreement (notarial contract)	Sets out property rights, financial contributions, treatment of joint debt, and what happens on breakdown.	The couple, while the agreement is in force.
Domestic Violence Act 116 of 1998	Defines a “domestic relationship” to include people living together in a relationship resembling marriage, qualifying them for protection orders.	An abused cohabitant against an abusive partner.
Children’s Act 38 of 2005	Gives parents of children of the relationship a route to parental responsibilities and rights (care, contact, guardianship).	The children of the relationship and their parents.
Maintenance Act 99 of 1998	Entitles a child of a cohabiting relationship to claim maintenance from either parent, on the same footing as a child of married parents.	The child of the relationship.

None of these layers creates a marriage or its equivalent. Each addresses one defined slice of what would otherwise be a legal vacuum.

Entering a Formal Cohabitation Agreement

A cohabitation agreement is a notarial contract — both parties must sign it before a notary public for it to be enforceable. It is the principal tool cohabitants have for creating the property and financial obligations that the law will not infer from living together.

Typical clauses cover:

• Ownership of, and contributions to, the joint home
• Carve-outs for separate property brought into the relationship
• Treatment of joint debt, including bond, vehicle finance, and credit cards
• Household-expense contributions and a default split
• What happens to shared assets on breakdown — division, buy-out, sale
• Recognition of contributions by a homemaker or stay-at-home parent as economic, not gratuitous
• Treatment of assets on death of either party

The agreement is not a marriage. It terminates on breakdown or death unless renewed. Notarial services in the South African market commonly quote between R1,200 and R1,700 for drafting and notarisation. Fees are quoted per file after review; complex estates can vary above this band.

The firm has a Notary and Conveyancer on staff (Amanda le Roux in Bedfordview) and handles cohabitation-agreement drafting as part of its notarial and family-law work.

Children of the Relationship

Cohabiting parents carry the same legal obligations to their children as married parents. The route by which each parent acquires parental responsibilities and rights differs:

Parent	How parental responsibilities and rights are acquired
Mother	Automatically, from birth (section 18 of the Children’s Act 38 of 2005).
Married father	Automatically, if married to the mother at the time of conception or birth.
Unmarried biological father — cohabited with the mother	Automatically, if he lived with the mother at the time of the child’s birth or at any time thereafter (section 22 of the Children’s Act 38 of 2005).
Unmarried biological father — never cohabited	Must apply to the Children’s Court for an order, or conclude a parental responsibilities and rights agreement with the mother registered with the Family Advocate or made an order of court.

Burger Huyser Attorneys’ Family Law practice, headed by Director Anna-Mi Nel, advises on parental responsibilities and rights applications and on parental responsibilities and rights agreements for unmarried fathers, with Family Court work run from the Sandton, Roodepoort, Bedfordview, and Pretoria branches.

If the relationship ends, the Children’s Court deals with care, contact, and guardianship disputes involving the children; the Maintenance Court deals with child maintenance on the same footing as any other child.

What Happens When the Relationship Ends

There is no “divorce” process for cohabitants — the relationship simply ends, and any property and financial claims are governed by the cohabitation agreement if one was signed.

• With a cohabitation agreement: the agreement’s breakdown clauses govern the division of property, treatment of joint debt, and any agreed maintenance between the partners.
• Without a cohabitation agreement: cohabitants have no automatic claim to joint property or assets accumulated during the relationship. The universal partnership doctrine requires evidence of a joint commercial enterprise, not a romantic household, and will not be inferred from cohabitation alone.
• Children-related disputes (care, contact, maintenance) follow the Children’s Court and Maintenance Court processes.
• Domestic violence allegations follow the Protection Orders process under the Domestic Violence Act.

Inheritance, Estate, and Next-of-Kin Issues

A surviving cohabitant does not inherit from a deceased partner through intestate succession. The Intestate Succession Act 81 of 1987 sets out the order of intestate heirs (spouse, descendants, parents, siblings, and more remote relations), and “cohabitant” is not on that list. Without a valid will, a surviving cohabitant can be left with no enforceable claim against the deceased’s estate — even after decades of living together and shared contribution to a household.

Two further estate and next-of-kin points are worth noting:

• Medical-decision authority. A cohabitant has no automatic right to consent to medical treatment for an incapacitated partner. The practical tool is a medical power of attorney or a living will naming the partner as the decision-maker.
• Practical step. Each cohabitant should have a valid will naming the other as heir (or at least acknowledging the relationship), and the will should be paired with a cohabitation agreement that addresses what happens on death.

Practical Steps for Couples Considering Cohabitation

Couples who want the kind of protection that marriage provides automatically can build it up themselves in advance. The list below is the practical equivalent of a marriage-like safety net for a couple who has chosen not to marry.

1. Discuss and document expectations around finances, property, and debt before moving in together.
2. Execute a notarial cohabitation agreement if either party wants enforceable property or financial rights.
3. For couples with children, ensure both parents have documented parental responsibilities and rights — particularly unmarried fathers who have never cohabited with the mother.
4. For couples where one partner is financially dependent, agree on a maintenance arrangement and document it.
5. Each partner should have a valid will naming the other appropriately.
6. Each partner should consider a medical power of attorney and an enduring power of attorney.

Frequently Asked Questions

Does cohabitation create a “common law marriage” in South Africa?

No. South African law does not recognise cohabitation as creating a marriage or any equivalent status, regardless of how long the couple lives together. The Constitutional Court’s decision in Bwanya v Master of the High Court, Cape Town confirmed no universal partnership arises automatically from long-term cohabitation. Cohabitants have only the protections they explicitly create through contract or that specific statutes (Domestic Violence Act, Children’s Act, Maintenance Act) give them.

How long do you have to live together to be recognised as a couple in South Africa?

There is no fixed period. No length of cohabitation converts the relationship into a marriage or creates automatic legal duties. Couples who want enforceable obligations must put them in writing through a notarial cohabitation agreement.

Are children born to cohabiting parents treated the same as children of married parents?

Yes. An unmarried biological father automatically acquires parental responsibilities and rights if he lived with the mother at the time of the child’s birth or at any time after (section 22 of the Children’s Act 38 of 2005). Where he has not cohabited with the mother, he must apply to the Children’s Court or conclude a parental responsibilities and rights agreement. The mother has automatic parental responsibilities and rights at birth.

Can a cohabitant inherit from a deceased partner?

Not automatically through intestate succession. Cohabitants are not on the intestate succession list under the Intestate Succession Act 81 of 1987. A surviving cohabitant inherits only if the deceased left a valid will naming them.

Can a cohabitant get a protection order against an abusive partner?

Yes — the Domestic Violence Act 116 of 1998 defines a “domestic relationship” to include people living or having lived together in a relationship that resembles marriage, qualifying cohabitants for protection orders on the same footing as spouses.

Can a cohabitation agreement be made legally binding?

Yes — both parties must sign it before a notary public for it to be enforceable. The agreement typically covers property, financial contributions, joint debt, and what happens on breakdown or death. Notarial services in the South African market commonly quote between R1,200 and R1,700 for drafting and notarisation.

While the legal answer to “what are the requirements for cohabitation” is that there are essentially none, the practical protections cohabitants commonly need — a notarial cohabitation agreement, parental responsibilities and rights for an unmarried father, a will naming the partner — are the kind of work Burger Huyser Attorneys’ Family Law practice handles across its Gauteng branches.
