The binding legal principle established is that: (1) An unregistered customary law union is not, on its own, a cause of action at common law for the distribution of assets acquired during cohabitation; (2) Where a party to an unregistered customary union seeks distribution of assets, a recognized cause of action must be properly pleaded, such as unjust enrichment, tacit universal partnership, or joint ownership; (3) The pleading must contain factual assertions (not mere conclusions or legal submissions) that establish the elements of the chosen cause of action; (4) Defective pleadings that fail to disclose a proper cause of action cannot be remedied by evidence led at trial - the defect must be cured by amendment before trial; (5) Courts should not treat unregistered customary unions as if they were marriages subject to the Matrimonial Causes Act for purposes of asset distribution.
