What are the 3 Types of Cohabitation Agreements in South Africa?

Cohabitation agreements in South Africa fall into three distinct legal forms: a notarial cohabitation agreement, executed before a Notary Public and capable of being registered against immovable property under the Alienation of Land Act 68 of 1981; a contractual cohabitation agreement, a written agreement between the partners that governs financial and personal arrangements without notarial execution; and a universal partnership agreement, which can be express (written into a cohabitation agreement) or tacit (implied from the couple’s conduct and recognised by the Constitutional Court). The form chosen determines whether the agreement is enforceable against third parties, whether it can be registered against fixed property, and how the contract is interpreted at dissolution.

Why the “Type” Matters in South African Law

Common-law cohabitation in South Africa carries no automatic matrimonial property regime. There is no default accrual system, no default duty of support, and no statutory sharing of assets on breakdown — the protections that apply automatically to a married couple under the Matrimonial Property Act do not extend to unmarried partners simply because they live together.

That gap is precisely why the form of the agreement matters. A couple’s choice of document determines whether the arrangement survives contact with property law, third-party creditors, and the dissolution process. Choosing the wrong form — or omitting a written agreement altogether — leaves the relationship governed only by what the courts can infer from conduct, which is where the universal partnership doctrine enters.

The Constitutional Court’s recognition of the tacit universal partnership in matters such as Beadica 231 CC v Trustees, ITCO (Pty) Ltd and Women’s Legal Centre v President of the Republic of South Africa means that a couple can end up with a partnership-style claim at separation even without a written agreement. Understanding the three legal forms is therefore not merely an academic exercise — it is a protective step, not a discretionary one.

Type 1: Notarial Cohabitation Agreement

A notarial cohabitation agreement is executed before a Notary Public — a separate admission from attorney admission — who verifies the identity of the parties, confirms their legal capacity, witnesses their signatures, and retains the original in the Notary’s protocol. From there the agreement can be lodged against the title deed of immovable property under the Alienation of Land Act 68 of 1981.

Registration against the title deed does two things at once. It gives the agreement priority over later creditors and bondholders, and it puts third parties (future buyers, executors on death, a trustee in a partner’s subsequent insolvency) on notice of the partners’ respective claims over the property. That notice function is what distinguishes the notarial form from a private written contract.

In Gauteng, the going drafting fee for a standard notarial cohabitation agreement currently sits in the R1,200 to R1,700 all-inclusive band, covering the Notary’s professional fee, the drafting of the agreement, and execution. The fee rises where the document is unusually long, where it includes trust structuring, or where the property being registered against is itself subject to an existing bond that requires the bondholder’s consent.

The notarial form is the only one of the three types capable of binding the parties’ matrimonial-property position in a way that affects land registration. It is the form to choose where the couple owns immovable property together or individually, or where one party is contributing to the other’s bond or capital repayments.

Type 2: Contractual Cohabitation Agreement (Written but Not Notarial)

A contractual cohabitation agreement is a written agreement between the partners, signed by both and usually witnessed, but not executed before a Notary Public and not registered against any title deed.

It governs the internal relationship: contribution of household expenses, treatment of joint assets acquired during the cohabitation, ownership of each party’s separate property brought into or kept outside the relationship, allocation of debt, and what is to happen on separation or death. In effect, it is a private commercial contract between two people who happen to share a household.

The agreement is enforceable between the parties under ordinary South African contract-law principles — capacity, consensus, lawful object, and a sufficiently certain undertaking. It is not, however, binding on a third party who takes without notice of it. A bondholder, a creditor of one partner, or a later purchaser of immovable property is not obliged to give effect to a private contractual arrangement they have never been shown.

The contractual form is the most common on the South African market for couples who want certainty about day-to-day financial arrangements without the cost of notarial execution. It can be drafted by an attorney who is not a Notary, which widens the pool of available practitioners and reduces the cost relative to the notarial form.

Type 3: Universal Partnership Agreement (Express or Tacit)

A universal partnership is a common-law partnership covering all of the joint commercial activity between the parties, or covering the relationship itself where the couple has held itself out as a commercial enterprise. It comes in two sub-forms.

The express form is written into a cohabitation agreement, expressly acknowledging that a universal partnership exists between the parties and stating how its assets and liabilities are to be divided on dissolution. The express form gives the couple certainty on the same point that a tacit universal partnership claim would otherwise be litigated.

The tacit form arises from the conduct of the parties without any written agreement at all. The Constitutional Court has held that a tacit universal partnership can exist between cohabiting partners if three elements are met:

1. Each party contributes something — money, work, or skill.
2. The purpose of the joint activity is to make a profit or to jointly accumulate.
3. The parties intend to share that profit or accumulation.

If all three are established, a partnership exists as a matter of law, and on dissolution its assets are split — the starting point being equal shares, adjusted for actual contributions. Because the claim can be raised by either party in the absence of any written document, this is the form most likely to be litigated at separation. It is also the form most often overlooked while the relationship is intact.

What Each Type Cannot Do

None of the three types converts a cohabitation into a marriage. There is no common-law marriage by cohabitation in South Africa, and the Recognition of Customary Marriages Act and the Civil Union Act do not extend to unmarried cohabitants. A cohabitation agreement, in any form, does not create a duty of maintenance between former partners (unless specifically contracted) and does not give automatic parental rights over a partner’s child.

A notarial cohabitation agreement also does not, on its own, affect the matrimonial-property system of any later marriage. It sits alongside, not in place of, an antenuptial contract. Couples who intend to marry and want to vary the default marriage regime still need an ANC, executed and registered within the timeframes set by the Matrimonial Property Act, in addition to (or instead of) any cohabitation document.

Frequently Asked Questions

What is the most common type of cohabitation agreement in South Africa?

The contractual (written, non-notarial) form is the most common because it is the cheapest and the simplest to draft, but it does not bind third parties. Where the couple owns immovable property together or individually, the notarial form is the only one that can be registered against the title deed.

Can a cohabitation agreement be registered against property in South Africa?

Only if it is executed before a Notary Public. The agreement is then lodged in the Notary’s protocol and can be registered against the title deed under the Alienation of Land Act 68 of 1981, giving third parties (bondholders, buyers, executors) notice of the partners’ claims over the property.

Do cohabiting partners have a universal partnership even without a written agreement?

Yes. The Constitutional Court has held that a tacit universal partnership can be established between cohabiting partners if each contributed something, the purpose was to jointly accumulate, and the parties intended to share the accumulation. The claim is raised at dissolution if there is no written agreement to govern the split.

Is a cohabitation agreement the same as an antenuptial contract?

No. An antenuptial contract (ANC) is signed before marriage and varies the matrimonial property regime that applies to the marriage. A cohabitation agreement governs the period of unmarried cohabitation only. Each has its own legal framework and its own form requirements.

How much does a notarial cohabitation agreement cost?

A standard notarial cohabitation agreement in Gauteng currently drafts in the R1,200 to R1,700 all-inclusive band, which covers the Notary’s professional fee, the drafting of the agreement, and execution. The fee rises if the agreement is unusually long, includes trust structuring, or needs to be registered against a property that is itself bonded.

Can a single person cohabiting with a partner draft a one-sided agreement?

Yes, but it carries risk. An agreement drafted entirely by one party’s attorney, signed by the other without independent legal advice, can be challenged for duress, undue influence, or unconscionability if the terms are grossly one-sided. The defensible practice is for each party to take independent legal advice before signing, which the Notary will usually require in any event.
