The Ugandan Court of Appeal, in the case of Kevin Musisi v Tom Mugerwa and Another, Civil Appeal No. 17 of 2023, delivered a significant ruling on November 2, 2026. This judgment, identified as [2026] UGCA 340, clarifies crucial aspects of property law in Uganda, particularly concerning agency, co-ownership, and property occupation. The court's decision provides definitive guidance on the enforceability of property transactions conducted by agents and the rights and limitations of joint tenants.

The core of the dispute in Kevin Musisi v Tom Mugerwa power of attorney revolved around the validity of a sale conducted by an agent and the authority of a joint tenant to act unilaterally. The appellate court meticulously examined the legal requirements for such transactions, ultimately setting precedents that reinforce the need for strict adherence to established legal procedures in property dealings. This ruling is poised to influence how property lawyers and individuals approach sales and co-ownership arrangements across the country.

A primary finding of the court was that any sale of property executed by an agent without a properly registered power of attorney is legally unenforceable. This emphasizes the critical requirement for formal documentation and registration when an agent acts on behalf of a principal in property transactions in Uganda, ensuring that all parties are protected and the transaction holds legal weight. The absence of a registered power of attorney renders an agent's sale invalid, highlighting a fundamental safeguard in Ugandan property law.

Furthermore, the court unequivocally stated that a joint tenant cannot unilaterally bind a co-owner in property matters. This principle underscores the distinct nature of joint tenancy, where each owner holds an undivided interest, and significant decisions, especially those affecting the ownership or disposition of the property, typically require the consent or involvement of all co-owners. This ruling reinforces the collective nature of joint ownership and prevents individual tenants from making decisions that could prejudice the interests of others.

Finally, the judgment clarified that excessive occupation of a property constitutes trespass. This aspect of the ruling addresses situations where an individual occupies land or premises beyond their rightful entitlement or agreed-upon terms. It establishes that such prolonged or unauthorized presence is not merely a breach of contract but a direct infringement on property rights, legally categorized as trespass, thereby providing property owners with a clear legal recourse against unauthorized occupants.

The pronouncements in [2026] UGCA 340 carry significant implications for legal practitioners and property owners alike. Lawyers advising on property transactions in Uganda must ensure that any agent acting on behalf of a principal has a properly registered power of attorney, as sales without one are unenforceable. This necessitates thorough due diligence to verify the authenticity and registration status of such instruments before proceeding with any sale or transfer.

Moreover, practitioners should counsel joint tenants on the limits of their authority, as they cannot unilaterally bind co-owners. This requires clear communication regarding the need for collective decision-making in matters affecting jointly owned property. Additionally, the ruling serves as a crucial reminder to clients that excessive occupation of property can constitute trespass, providing a strong legal basis for addressing unauthorized or prolonged occupancy issues in Uganda.
