Boundary Wall Ownership Dispute: Presumption of Party Wall

A landowner filed a claim against a neighboring property owner, alleging that a wall constructed on the boundary was a party wall and demanding that the neighbor contribute to its costs, while the neighbor asserted the wall was exclusively their own. The court of appeal ruled in favor of the neighbor, finding insufficient proof that the wall was shared property, leading the initial claimant to appeal based on the fact that the construction encroached upon the common boundary line. The highest court quashed the lower court's decision, reasoning that a wall built on the boundary line between two properties is legally presumed to be a party wall unless the neighbor can provide proof to the contrary, thereby shifting the burden of proof regarding ownership to the party asserting sole ownership.
