Swiss Franc Loans in Alsace – Lawyer for Cross-Border Workers - DANA Avocats

Swiss franc loans in Alsace

Updated September 28, 2026

Around Mulhouse, Saint-Louis and the Sundgau, cross-border workers employed in the Basel region often took out Swiss franc mortgage loans with regional banks. Many of these contracts contain indexation clauses whose transparency can be challenged.

The firm analyzes the contract and the pre-contractual documents, then decides on the strategy: action on the merits, negotiation, or appeal against a decision already handed down.

Disputes fall in particular within the jurisdiction of the Judicial Courts of Mulhouse, Colmar and Strasbourg, and on appeal of the Colmar Court of Appeal.
