South African law on correcting an unintended matrimonial property regime, section 21 MPA applications, spouse consent, and negligence claims against attorneys.
Written by Roy Bregman, an admitted attorney with over 51 years' experience in South African family and
matrimonial property law.
A client asked: “Can a court correct a matrimonial property regime where
both spouses intended to conclude an antenuptial contract, but it was not
executed or registered due to attorney negligence—and can one spouse be
compelled to participate in such a correction?”
Can You Force Your Spouse to Change Your Matrimonial
Property Regime After Attorney Negligence?
Key Takeaways
- South
African law allows spouses to correct an unintended matrimonial property
regime caused by attorney or notarial negligence, but only with a joint
High Court application and no prejudice to creditors.
- Section
21(1) of the Matrimonial Property Act 88 of 1984 is the primary mechanism
to change the matrimonial property system after marriage, and it expressly
requires both spouses’ consent.
- If
one spouse refuses to cooperate (for example, because they benefit from
being married in community of property), the court will not impose a new
regime unilaterally.
- The
aggrieved spouse’s realistic remedy is usually a professional negligence
claim against the attorney or notary whose failure caused the wrong
matrimonial regime.
South African Legal Framework on Matrimonial Property
Systems
Legal
principles: correcting an unintended matrimonial property system
Default regimes and antenuptial contracts
South African law starts from the principle that, absent a
valid ANC executed and registered before marriage, spouses are married in
community of property by default. Where the parties in fact intended to marry
out of community (with or without accrual), but attorney or notarial negligence
prevented a valid ANC from coming into effect, the law provides two broad
routes to seek correction.
First, if an ANC was validly executed before the marriage
but not registered timeously due to error or oversight, the High Court can
authorise condonation of late registration under the Deeds Registries Act, with
retrospective effect, provided creditors are notified and not prejudiced.
Second, if no valid ANC exists and the parties wish to change the system after
marriage, section 21(1) of the Matrimonial Property Act 88 of 1984 permits a
joint application to change the matrimonial property regime, again subject to
sound reasons and protection of creditors.
Section 21(1) Matrimonial Property Act: Postnuptial
change
Statutory
framework: section 21 of the Matrimonial Property Act
Section 21(1) of the Matrimonial Property Act is the central
statutory authority for postnuptial changes to the matrimonial property regime.
It allows a husband and wife, after their marriage, to jointly apply
to the High Court for leave to change their matrimonial property system,
provided there are sound reasons, proper notice to creditors, and no prejudice
to creditors or third parties.
Courts have repeatedly used section 21 to give effect to the
spouses’ true intention where the wrong regime resulted from mistake or
professional negligence. However, the wording “husband and wife may jointly
apply” is crucial: the statute provides no basis for a unilateral application
by only one spouse to change the regime against the will of the other.

Regimes
Case
law: intention, negligence and postnuptial correction
Applications based on mistake and negligence
Several reported decisions illustrate how the courts have approached
these applications. In cases such as Ex parte Oosthuizen, Ex
parte Spinazze and Another and Ex parte Burger, the courts
granted leave to change the matrimonial property regime where the parties
intended to marry out of community but failed to execute or register the ANC
correctly. The courts emphasised two key elements: the genuine common intention
of both spouses, and the absence of prejudice to creditors.
Rectification where an ANC exists
Rectification is also available where an ANC exists but does
not reflect the spouses’ true intention because of a common mistake. In PV
v EV (SCA), the court confirmed that an antenuptial contract, as a
written agreement, can be rectified where the written terms do not reflect the
parties’ actual agreement, provided sufficient evidence of the common intention
is placed before the court. Rectification, however, presupposes a valid ANC;
where there is none, spouses must use section 21.
Must Both Spouses Consent to the Change?
The
joint-application requirement: can one spouse be compelled?
Why the court requires a joint application
The decisive issue in the client’s question is whether a
husband can compel his wife to join a court application to change the regime
where she now benefits from the existing system. Both the condonation route
(late registration of a validly executed ANC) and a section 21(1) application
are premised on a joint approach by both spouses and on the proposed regime
reflecting their shared intentions.
Because section 21(1) expressly requires that “a husband and
wife may jointly apply”, the courts have consistently treated the change of
matrimonial regime as a consensual adjustment of the patrimonial consequences
of marriage. If the wife refuses to cooperate because she prefers the more
favourable consequences of being married in community of property, the husband
cannot force her to support the application, and the court will not impose a
new regime unilaterally.
Practical consequences and the husband’s remedy
What if one spouse refuses?
Where one spouse refuses to participate, the marriage
remains governed by the existing matrimonial property regime, usually in
community of property if no valid ANC was executed and registered. The
husband’s frustration with this outcome does not create a power to override his
wife’s autonomy or to compel her participation in a joint application.
Attorney or Notary Negligence: The Claim for Damages
In practice, the aggrieved spouse’s realistic remedy lies in
a professional negligence claim against the attorney or notary whose failure to
execute or register the ANC properly caused the loss. South African courts have
recognised such claims, for example in Van Heerden Brummer Inc v Bath (SCA),
where an attorney was sued because an invalid ANC left the client worse off on
divorce; the measure of damages is typically the financial difference between
the intended regime and the regime that actually applies.
Conclusion
South African law recognises that attorney or notarial
negligence can result in spouses being married under a matrimonial property
regime they never intended, and it provides mechanisms to correct this by way
of court-approved, postnuptial changes. However, those mechanisms are
inherently consensual: both late registration of an ANC and a section 21(1)
application to change the matrimonial property system require a joint
application by both spouses, and the courts will not impose a new regime
against the will of one spouse.
If a wife is content to remain married in community of
property because it benefits her, the husband cannot compel her to support a
High Court application to alter the regime, even if the original intention was
to marry out of community under an ANC. His primary remedy is instead to
explore a professional negligence claim against the practitioner whose failure
deprived him of the intended matrimonial protection.
FAQ section
Q1: We intended to marry out of community, but no ANC was
signed or registered. Are we married in community of property?
Yes. If no valid ANC was executed and registered before the marriage, the
default position in South African law is a marriage in community of property.
Q2: Can I bring a section 21 application without my
spouse’s consent?
No. Section 21(1) of the Matrimonial Property Act requires a joint application
by both spouses; the court will not grant relief on a unilateral application.
Q3: What if my spouse refuses because they benefit from
the current regime?
If your spouse refuses to join the application, the existing matrimonial
property regime remains in place, even if it was not your original intention.
Q4: Is there any remedy if the problem was caused by
attorney negligence?
Yes. You may have a professional negligence claim against the attorney or
notary whose failure to execute or register the ANC caused you financial loss.
If you and your spouse are married under a regime you
never intended because of attorney or notarial negligence, or if your spouse is
