Cohabitation has become a deliberate and popular lifestyle choice for many South African couples. Long‑term partners often share homes, expenses, investments, and future goals, functioning much like a married household.
However, from a legal and financial planning perspective, cohabitation and marriage are not treated the same. This disconnect creates a number of planning gaps that can have serious financial consequences if the relationship ends or one partner passes away.
Regularly financially savvy individuals are unknowingly exposed to risk simply because they assume the law provides protection where it does not.
Cohabitation Is Not a Legal Status
South African law does not recognise “common-law marriage.” Living together, even for decades, does not automatically create:
- A matrimonial property regime
- A reciprocal duty of support between partners
- Automatic inheritance rights
- A statutory framework for dividing assets on separation
While courts have occasionally intervened to prevent unfair outcomes, these remedies are limited, uncertain, and usually require costly litigation. In practice, couples may appear financially organised but remain legally vulnerable.
Where the Law Does Offer Limited Recognition
Cohabiting partners are not entirely excluded from the legal system. Certain legislation recognises permanent life partnerships, but only for specific purposes. This fragmented recognition often creates a false sense of security.
Key areas of partial recognition include:
Medical Schemes
Medical schemes may allow a cohabiting partner to be registered as a dependant, subject to the scheme’s rules and sufficient proof of partnership. This enables families to share healthcare cover, but it does not extend to broader legal or financial protections.
Tax Treatment
Tax legislation adopts a more inclusive definition of “spouse,” recognising permanent heterosexual or same‑sex relationships of indefinite duration. This can result in meaningful benefits, such as:
- No donations tax on transfers between partners
- Estate duty exemptions on assets left to a surviving partner
- Capital gains tax rollover relief
However, favourable tax treatment does not equate to family‑law protection, particularly on separation.
Life Insurance and Beneficiary Nominations
Cohabiting partners can be nominated as beneficiaries on life policies and investments. Precision is critical, beneficiaries should be clearly identified by name and relationship to avoid disputes or delays at claim stage.
Children and Maintenance
When children are involved, marital status is irrelevant. Both parents have a legal duty to support their children, regardless of whether they are married, cohabiting, separated, or were never in a formal relationship.
Retirement Fund Death Benefits
Life partners may qualify as financial dependants under the Pension Funds Act. That said, retirement fund trustees must consider all dependants, and the ultimate allocation of death benefits is discretionary and evidence‑based.
Where the Real Financial Risks Arise
Outside these specific areas, the legal safety net falls away, often with significant consequences.
Property Ownership
If a shared home is registered in one partner’s name, that partner is the legal owner and may sell or encumber the property without consent. Claims based on unjust enrichment or “universal partnership” are possible but complex, expensive, and highly dependent on proof.
Household Assets
Movable assets typically belong to the person who paid for them unless agreed otherwise. Over time, informal arrangements blur ownership, making disputes difficult to resolve fairly.
Day‑to‑Day Finances
On separation, informal financial arrangements quickly unravel. Bank accounts, leases, debts, and service contracts remain with the named individual, often leaving one partner exposed and without recourse.
No Automatic Maintenance Rights
Unlike divorce under the Divorce Act, cohabiting partners generally cannot claim spousal maintenance on separation. While recent court decisions have expanded some protections for permanent life partnerships, these remedies are not automatic and require detailed substantiation.
Death and Intestate Succession
Dying without a will is particularly risky for cohabiting couples. Although intestate succession law has evolved, relying on post‑death litigation is emotionally and financially draining, and outcomes are never guaranteed.
Retirement Savings on Separation
There is no automatic right to share in a partner’s pension interest on separation. Where retirement assets are accumulated in one name, this can leave the other partner financially disadvantaged after years of contribution to the household.
The Practical Planning Solution
For couples who choose to live together, assumptions are not a strategy. The most effective protection comes from intentional, documented planning.
Cohabitation Agreements
A properly drafted cohabitation agreement can clarify:
- Ownership of property and assets
- Responsibility for liabilities
- Contributions to shared expenses
- Treatment of retirement savings
- Maintenance expectations
- Arrangements for pets and shared commitments
This significantly reduces uncertainty and conflict should the relationship end.
Estate and Financial Planning
Cohabiting partners should ensure their financial plans accurately reflect their intentions by:
- Drafting valid, up‑to‑date wills
- Aligning beneficiary nominations across policies and funds
- Appointing appropriate executors and trustees
- Providing for minor children through guardianship and fiduciary structures
Final Thoughts
Living together does not reduce the need for financial planning, it intensifies it. Without the automatic legal protections that accompany marriage, cohabiting couples must rely on clarity, consistency, and professional advice to protect what they are building together.
If you or your partner are cohabiting, now is the time to review your financial and estate plans to ensure they reflect the reality of your relationship, not the assumptions.
