Legal Protection Insurance: How to use it effectively

Most drivers have 'Legal Protection' insurance coupled with their car or home insurance, often without even knowing it. It is your best weapon against manufacturer's legal departments.

Triggering Coverage

From the first refusal of coverage by the manufacturer, contact your legal protection. They will open a file and cover the costs of an independent expert (often mandatory to go to court) as well as lawyer fees.

Don't let your own insurance discourage you

Insurance lawyers tend to filter cases to minimize their costs. If they feel your case is 'difficult', provide them with our technical documentation and proof that a collective action is underway. Insist that they appoint an automotive expert.

Are you affected by this problem?

Join the national registry to defend your rights under the warranty of hidden defects (Art. 1641).
