Uganda High Court: Upholds Proprietary Estoppel, Sets Aside Damages

On October 20, 2026, the High Court of Uganda, acting as an appellate court, upheld a finding of proprietary estoppel for an individual named Gahungu, simultaneously determined that no valid customary marriage existed, and set aside an award of general damages in the case of Banziziki Elina and Another v Batamuliza Felesta.

In this appellate decision, the High Court reviewed a lower court's findings, affirming the application of the equitable doctrine of proprietary estoppel in favour of Gahungu. This doctrine typically prevents a legal owner from asserting their strict legal rights over property when another party has acted to their detriment based on an assurance or expectation concerning that property. Concurrently, the court made a definitive finding that a valid customary marriage had not been established, which carries significant implications for personal status and property rights under Ugandan law. Furthermore, the appellate court intervened in the assessment of damages, specifically setting aside an award for general damages, suggesting that the original award may have been improperly assessed or lacked sufficient legal basis.

This ruling holds substantial legal significance for practitioners engaged in land disputes, family law, and civil litigation within Uganda. The affirmation of proprietary estoppel reinforces its vital role as a mechanism to prevent unconscionable conduct in property matters, particularly where informal agreements or understandings exist. The court's finding on the invalidity of the customary marriage underscores the strict legal and customary requirements for such unions, impacting issues like inheritance, spousal support, and property division upon separation or death. The decision to set aside general damages serves as a crucial reminder to legal professionals about the rigorous standards required for proving and quantifying damages to withstand appellate scrutiny.

The legal context for this case involves the High Court of Uganda exercising its appellate jurisdiction over decisions from lower courts. Proprietary estoppel is a well-established equitable doctrine in common law jurisdictions, including Uganda, applied to protect individuals who have relied to their detriment on assurances regarding property. Customary marriages in Uganda are governed by specific legislation, such as the Customary Marriage (Registration) Act, and various customary laws, which dictate the conditions for their validity. The assessment of general damages in civil cases is guided by principles derived from case law, requiring a clear nexus between the breach or tort and the alleged harm. The key parties involved are Banziziki Elina and Another, and Batamuliza Felesta, with Gahungu being a central figure benefiting from the proprietary estoppel finding.

Practitioners should meticulously advise clients on the stringent requirements for establishing proprietary estoppel, emphasizing the need for clear assurances and demonstrable detrimental reliance. In matters concerning customary marriages, it is imperative to ensure that all legal and customary prerequisites are strictly adhered to, as a finding of invalidity can have profound and far-reaching consequences for individuals and their families. Furthermore, attorneys must pay scrupulous attention to the proper pleading, proof, and quantification of damages, particularly general damages, to ensure awards are robust and defensible on appeal.
