Joan Marie Muller and Another v Cara Dorothy Masureik and Others

Joan Marie Muller (first applicant) was married out of community of property with accrual to Howard Alexander Muller. Divorce proceedings were initiated in June 2010 but remained pending 15 years later. Mr Muller was the sole registered owner of their matrimonial property, purchased in 2003. On 19 March 2022, Mr Muller sold the property to the respondents. The first applicant's attorney was informed but no interdict was filed. Transfer occurred on 24 June 2022. The respondents made several offers to facilitate vacant possession, including offering the first applicant R300,000 plus an additional R100,000, which were rejected. The respondents then brought eviction proceedings under the PIE Act. The first applicant opposed eviction claiming quasi-proprietary rights arising from her accrual claim and invoking the doctrine of notice. The second applicant, Astrid Muller Equestrian (a business operated by the couple's daughter), also occupied the property and relied on the first applicant's grounds. The high court granted the eviction order on 14 December 2023. Leave to appeal was refused by both the high court and two judges of the SCA. The applicants then applied for reconsideration under s 17(2)(f) of the Superior Courts Act.

• Whether a spouse married out of community of property with accrual has a vested right in the other spouse's assets during the subsistence of the marriage
• Whether an accrual claim pending divorce constitutes a quasi-proprietary right enforceable against third-party purchasers
• Whether the doctrine of notice applies to protect a spouse's contingent accrual rights against a purchaser with knowledge of those rights
• Whether the sale and transfer of matrimonial property during divorce proceedings is contrary to public policy or constitutional rights
• Whether the threshold requirements for reconsideration under s 17(2)(f) of the Superior Courts Act have been met
• Whether eviction under the PIE Act was just and equitable in the circumstances
• What is the correct form of order when a s 17(2)(f) application fails to meet the jurisdictional threshold

The order of dismissal by the two judges of the SCA refusing leave to appeal was confirmed. The applicants were ordered to pay the respondents' costs jointly and severally, the one paying the other to be absolved.

A spouse married out of community of property with accrual has only a contingent right to share in the accrual of the other spouse's estate, which vests only upon dissolution of the marriage. This contingent right is not a proprietary right (real or personal) and cannot be enforced against third-party purchasers, even where such purchasers had knowledge of the pending divorce and potential accrual claim. The doctrine of notice does not apply where the claimant has no proprietary right in the property. A spouse has no vested right in the other spouse's assets during the subsistence of the marriage and no general right to prevent the other spouse from dealing freely with their own property. The threshold under s 17(2)(f) of the Superior Courts Act (as amended) requires demonstration that a grave failure of justice would result or the administration of justice would be brought into disrepute before reconsideration is warranted.

The majority judgment (Kgoele JA) made extensive obiter remarks on the proper form of order in s 17(2)(f) applications, preferring confirmation of dismissal over striking from the roll, and emphasizing principles of finality. Kgoele JA observed that reconsideration under s 17(2)(f) is not a parallel appeal process or mechanism to revisit merits, but a residual safeguard to prevent miscarriage of justice. The minority (Keightley JA) expressed the view that s 17(2)(f) involves a two-stage procedure: first establishing jurisdictional facts, then considering merits. Without satisfying the jurisdictional requirements, the Court has no power to confirm or dismiss and must strike the matter from the roll. The majority also commented that developing the common law as proposed would require a complete overhaul of matrimonial law and existing jurisprudence on the right to adequate housing. The Court noted that any right the first applicant may have had to reside in the property was an incident of the duty of support owed by the husband, which became nugatory upon sale and transfer of the property.

This case clarifies the legal nature of accrual rights under the Matrimonial Property Act, confirming that such rights are contingent and do not vest until dissolution of the marriage. It establishes that contingent accrual rights do not constitute proprietary rights capable of founding a defence based on the doctrine of notice against third-party purchasers. The judgment also addresses the interpretation of s 17(2)(f) of the Superior Courts Act following its 2024 amendment, with the majority and minority differing on the correct form of order when threshold requirements are not met. The case demonstrates the limits of constitutional arguments in matrimonial property disputes and reaffirms that matrimonial property rights during the subsistence of a marriage out of community of property do not prevent a spouse from freely dealing with their own property.
