Civil law — Banking dispute

Banking dispute lawyer in Metz and Luxembourg

Questionable fees, a poorly disclosed loan, abusive listing, refused borrower insurance: disputes with a bank or insurer are common and technical. The challenge is to pinpoint the breach, quantify the loss and choose the most effective route — mediation or court. My role is to restore the balance.

Does this apply to you?


These situations warrant a review of the file — and often a simple lawyer's letter is enough to unblock matters.

  • Your bank charged fees you consider irregular or disproportionate.
  • You dispute a loan's rate (APR) or a failure to inform when it was taken out.
  • You are met with a FICP or FCC listing you consider unjustified.
  • Your borrower insurance refuses to cover a claim (sick leave, disability).
  • You stood as guarantor and the amount claimed seems disproportionate to your income.
  • An insurer (motor, home) refuses to compensate you or applies a questionable exclusion clause.

Identifying the breach and quantifying the loss

A banking dispute is won on precision. The firm reviews the statements, the loan offer, the general terms and the correspondence to characterise the breach: irregular fees, an APR error, a failure to warn a non-expert borrower, a disproportionate guarantee, an unfair term. The loss is then quantified item by item — the condition for both credible negotiation and solid litigation.

Banking mediation, an often mandatory first step

In most cases, banking mediation is a mandatory step before any court action. Free of charge, it often resolves the dispute without trial — provided the file is presented on solid legal grounds. The firm prepares the complaint, refers the matter to the competent ombudsman and follows the process.

Litigation before the judicial court

If the deadlock persists, the matter is brought before the judicial court (representation by a lawyer mandatory above €10,000). The firm handles the specific actions: APR challenge, nullity of a disproportionate guarantee, removal of an unjustified listing, liability for breach of the duty to inform and warn.

Frequently asked questions


What can I do if my bank refuses to acknowledge a breach?

Three steps: 1) a detailed written complaint to customer services; 2) referral to the banking ombudsman (free, mandatory before any court action in most cases); 3) if the deadlock persists, an action before the judicial court with a quantified, supported file. The firm assists with all three.

Can I challenge bank fees or a loan's rate?

Yes. Irregular fees or a miscalculated annual percentage rate can be challenged, as can a failure to inform when the loan was taken out. Reviewing the loan offer and statements determines the exact nature of the breach and the compensable loss.

I am listed with the Banque de France: what can I do?

An unjustified or wrongly maintained FICP or FCC listing can be the subject of a removal request, or even a liability action against the institution. The firm examines the lawfulness of the listing and takes the appropriate step.

Do I necessarily need a lawyer for a banking dispute?

Representation by a lawyer is mandatory before the judicial court above €10,000, and before the Court of Appeal. Below that, assistance remains strongly advised: a poorly presented banking file weakens even a well-founded claim.

Do you act for a dispute with a Luxembourg bank?

Yes. Admitted to the Metz and Luxembourg Bars, I act on both sides of the border. The rules differ (consumer law, mediation), and the cross-border France-Luxembourg practice is integrated from the first meeting.
