Key legal question
Whether the husband’s claim for repayment of funds secured by a mortgage on foreign immovable property is a real or personal action for jurisdiction purposes.
Extracted holding
The claim was personal, not real or mixed, because only the debt was sought, not enforcement of the mortgage right itself.
Extracted reasoning
Contractual or debt-based claims are personal even if they concern land; a mixed real action exists only when the claimant seeks both determination of the lien and payment. Since the husband claimed only the debt, Swiss courts had jurisdiction over the monetary claim.
