What does joint ownership mean?
Joint ownership of immovable property in South Africa is the situation where two or more parties hold the same property in prescribed shares. Those shares may be equal (the default) or unequal — the title deed will record the split. Every form of joint ownership in SA falls into one of two categories: ownership derived from a matrimonial regime (in community of property; out of community, with or without accrual), or ownership derived from a co-ownership arrangement between unmarried parties.
The distinction is not a technicality. The matrimonial regimes are governed by the Matrimonial Property Act 88 of 1984 and the Divorce Act 70 of 1979; co-ownership is governed by common-law principles supplemented by whatever co-ownership agreement the parties put in writing. The decisions each type of owner must make on a sale — whose consent is needed, whose signature goes on the transfer, how the proceeds are split — follow from which category the ownership falls into. Get this wrong and you risk a transfer being rejected at the Deeds Office.
Marriage in community of property
A marriage in community of property — the default SA matrimonial regime where the spouses did not sign an antenuptial contract (ANC) before the wedding — creates a single joint estate. Every asset either spouse owned before the marriage, and every asset acquired during the marriage, falls into the joint estate and is owned in equal undivided shares. So does every debt. The spouses cannot hold separate estates while married in community.
Section 15 of the Matrimonial Property Act is the critical provision for property transactions. It requires written spousal consent before one spouse can alienate or encumber immovable property forming part of the joint estate. Spousal consent is not optional, and it cannot be implied. On a sale, both spouses must sign the OTP (or one must hold a written power of attorney). On a transfer, both sign the transfer documents. On a bond registration, both sign the mortgage bond.
Skipping spousal consent is a common and serious error. A transaction entered into without the required consent is voidable at the instance of the non-consenting spouse under s 15(9) of the Act — meaning the aggrieved spouse can have the sale or bond set aside, with all the disruption that implies for an innocent purchaser. The Deeds Office will not register a transfer or bond without clear evidence of consent, so in practice the error surfaces early, but it is the buyer and the attorney who bear the cost of unravelling.
Marriage out of community — ANC without accrual
An antenuptial contract without accrual — sometimes called a “pure” or “cold” ANC — creates fully separate estates. Each spouse owns their own assets, contracts their own debts, and can deal with their own property without the other’s consent. There is no sharing of growth on divorce or death; what each spouse owned before the marriage, and what each acquired during, stays theirs.
For property transactions this is the simplest regime. The spouse whose name is on the title signs the OTP and the transfer documents alone. The other spouse is a stranger to the transaction. A s 15 spousal consent is not required — the Matrimonial Property Act’s consent regime applies to “joint estates” and “estates governed by community of property”, not to fully separate estates.
Marriage out of community — ANC with accrual
An antenuptial contract with accrual is the most common SA matrimonial regime for marriages entered into since the Matrimonial Property Act came into force in 1984. During the marriage, each spouse owns their own assets and contracts their own debts — so it behaves like an ANC-without-accrual regime for day-to-day transactions. But on divorce or death, the growth in each estate during the marriage is calculated, and the spouse whose estate grew less is entitled to half the difference. That equalisation claim is the “accrual”.
For property transfers, the position is identical to ANC without accrual: each spouse signs for their own property, no s 15 consent is required, and the transfer runs through the Deeds Office in the selling spouse’s name alone. The accrual mechanics only crystallise on divorce or death, and they are a monetary obligation rather than a real right in the property.
Civil unions and same-sex partnerships
The Civil Union Act 17 of 2006 permits two people, regardless of sex, to solemnise a civil union — legally equivalent to a marriage under the Marriage Act. Civil-union partners may choose the same matrimonial regime options as heterosexual couples: in community of property (the default), out of community without accrual, or out of community with accrual. The Matrimonial Property Act applies in identical terms — so civil-union partners married in community need the same s 15 spousal consent, and civil-union partners married out of community transact independently.
Life partners who have not solemnised a civil union are treated as unmarried co-owners for property law purposes, notwithstanding the length or commitment of the relationship. SARS, the Deeds Office and the banks look at the legal status, not the domestic arrangement. If you are in a long-term same-sex or different-sex partnership and you are buying property together without solemnising a civil union, draft a co-ownership agreement — it is the only framework that will protect both parties.
Co-ownership (non-married)
Two or more unmarried parties — friends, siblings, business partners, life partners — can hold a property together as co-owners in undivided shares. The default is equal undivided shares unless the title deed records otherwise. Co-owners share all the attributes of ownership pro rata: rights of use, rent, capital gain, and liability for rates, levies and maintenance.
| Issue | Default position | What a good agreement should do |
|---|---|---|
| Shares | Equal undivided | Match to deposit / bond contribution |
| Rates & levies | Pro rata to shares | Who pays; penalty for arrears |
| Maintenance | Pro rata to shares | Approval thresholds; builder selection |
| Sale of one share | Free to sell; other co-owners not protected | Right of first refusal to co-owner(s) |
| Exit / buy-out | Partition action in court | Valuation mechanism; cooling-off |
A co-ownership agreement is the single most valuable piece of paper in a multi-owner transaction. Draft it before transfer, not after — amendment requires agreement from every co-owner, which is precisely what gets hard when the relationship is strained.
Partition: what if co-owners fall out?
South African common law gives every co-owner the right to claim partition — the termination of co-ownership — at any time. Partition is a last-resort remedy, not a negotiation tactic. Where the property can be physically divided (e.g. adjoining farms) the court may order physical division; where it cannot (a single house, a sectional-title unit) the court orders a sale by auction and division of the net proceeds per each co-owner’s share. The actio communi dividundo is the formal name for the partition action.
See our broader Offer to Purchase guide for how a buy-out is typically structured where one co-owner sells their share to the other.
Frequently asked questions
Yes. Unmarried partners, including long-term life partners, can acquire property together as co-owners in undivided shares — typically 50/50 unless the title deed records other fractions. There is no statutory recognition of a common-law marriage in South Africa, so the co-owners are treated as strangers for transfer-duty and matrimonial purposes. That means: each signs the OTP and transfer documents separately; the bank runs affordability and FICA on each separately; and, critically, if the relationship ends, the property is divided under co-ownership law, not matrimonial law. Put a co-ownership agreement in place before the transfer: cover how instalments are split, who pays rates and maintenance, what happens on a break-up, and whether one co-owner has first refusal if the other wants out.
If you are married in community of property, the joint estate is divided equally on divorce — the property is either sold and the net proceeds split 50/50, or one spouse buys out the other at an agreed value. If you are married out of community with accrual, the property belongs to whichever spouse it was registered to, but the accrual calculation may require an equalisation payment. If you are married out of community without accrual, ownership simply follows registration — the spouse on the title keeps the property. If you are unmarried co-owners, the property is divided per the co-ownership agreement (or if none exists, per the respective shares in the title deed); either co-owner can compel a sale by instituting a partition action.
Yes. A co-ownership agreement is cheap insurance — typically R2,000 to R6,000 to draft, and it addresses every major friction point before the relationship or friendship is under pressure. Without one, South African common law fills the gaps: equal shares (even if one co-owner contributed more deposit), each co-owner free to force a partition at any time, no first refusal, no maintenance-cost allocation, no mechanism for one co-owner to buy out the other. Every one of those defaults is the opposite of what most co-owners actually want. Draft the agreement before transfer — amending after registration is possible but awkward, because any shift in the registered shares is itself a transfer for Deeds Office purposes.
Separately, in every case. South Africa taxes each spouse as an individual taxpayer regardless of matrimonial regime. Rental income from a jointly-owned property is apportioned by ownership share; transfer duty on acquisition is calculated on each co-owner’s share separately (and each co-owner has their own R1,210,000 zero-rated bracket); capital gains tax on disposal is computed on each co-owner’s share. The significance: two co-owners each pay transfer duty on their own 50% share, so the total duty on a R2,400,000 acquisition (R1,200,000 per share) is zero — whereas a single purchaser pays duty on the R1,190,000 slice above the threshold. Co-ownership is thus a modest transfer-duty benefit at the entry level.
