Key legal question
Whether the husband proved a reimbursement claim for renovation costs and mortgage amortization concerning the wife's villa.
Extracted holding
He did not prove that he paid the claimed renovation expenses or amortization amounts.
Extracted reasoning
Under Art. 8 CC, the claimant bears the burden of proof; the wife had no duty to prove her denials. The cantonal court's assessment that the facts were not proven bound the Federal Court.
