At Etienne Botha Attorneys, we frequently consult with clients who are ending long-term relationships where they lived together but never legally married. A widespread myth in South Africa is the concept of a "common-law marriage" the belief that if you live with a partner for a certain number of years, your relationship automatically converts into a legal marriage with automatic rights to assets or spousal maintenance. Under South African law, this concept does not exist. No matter how long you live together, cohabitation does not grant you the automatic statutory rights enjoyed by couples married under the Marriage Act or the Civil Union Act.
If you separate after years of living together without a signed, written Cohabitation Agreement, the baseline legal position is harsh: what is yours remains yours, and what is your partner's remains theirs. If the family home or vehicles are registered solely in your partner’s name, you have no automatic right to claim a share of them, nor do you have any claim against their pension fund or future financial support. A cohabitation separation does not pass through the family courts via a standard divorce action; instead, it is treated as a civil dispute over property ownership.
To claim a share of accumulated assets when no agreement exists, a separating partner must launch a formal civil action in the High Court or Regional Court. The most common action brought is a claim based on a universal partnership (societas universorum bonorum). To succeed, you must legally prove that you and your partner formed an implied partnership. This requires proving three strict elements: that both parties contributed to a common enterprise (either financially or through labor), that the enterprise was carried out for the joint benefit of both parties, and that the ultimate objective was to make a profit or accumulate joint wealth.
Proving a universal partnership is a complex, evidence heavy, and costly legal process. The court will closely examine historical bank statements, joint accounts, financial contributions to bond payments, and even domestic arrangements to see if a true commercial like partnership existed. While this litigation unfolds, partners do not have access to swift interim financial relief mechanisms (like a divorce Rule 43 application), making these separations highly unstable if not handled by an experienced legal team.
Please note that while spousal rights do not exist automatically in cohabitation, child care and maintenance laws remain unaffected. Both biological parents retain their strict legal obligations toward their children, regardless of whether they were married, cohabiting, or separated.
