Questão jurídica principal
Whether the chalet at Nendaz had been proved to be the husband's separate property rather than an acquêt.
Decisão extraída
The husband failed to prove separate-property status; the legal presumption of acquêt under Art. 200 al. 3 CC therefore applied.
Fundamentação extraída
The Federal Court held that once proof of the property's matrimonial mass failed, the lower court correctly treated it as an acquêt. The husband's attack was largely directed against factual findings and evidence assessment, which is not reviewable in reform proceedings.
