In interpleader proceedings, a claimant must prove ownership of attached property on a balance of probabilities by setting out facts and allegations which constitute proof of ownership. The common law presumption that possession proves ownership of movables does not operate where surrounding circumstances raise doubt about the claimant's ownership and suggest possible collusion with the judgment debtor. In such circumstances, the claimant must lead clear and satisfactory evidence of ownership beyond mere possession, including documentary proof such as receipts, registration books, or agreements of sale. Failure to produce such documents, particularly where the claimant has averred their existence, or to explain their non-availability, will result in dismissal of the claim.
