In interpleader proceedings, a claimant bears the onus of proving ownership on a balance of probabilities. While a vehicle registration book alone does not suffice as proof of ownership, when combined with an agreement of sale and corroborating conduct (such as immediate efforts to prevent execution by family members), it can constitute prima facie proof of ownership. The absence of a receipt does not automatically defeat a claim where other satisfactory documentation of purchase exists. Where a claimant and judgment debtor are closely related (such as brothers), the court must adopt a higher degree of circumspection and be alert to the possibility of collusion, but must decide the case on the evidence presented rather than on stereotypes or preconceived notions. Mere suspicions of forgery or collusion, without substantive evidence, are insufficient to defeat a properly documented claim.
