In some insurance contracts, you benefit from a "legal protection" guarantee, which allows you to be defended and represented in certain cases. You may also have a specific legal protection contract. In this case, your insurer can reimburse you for the costs of the action. More info here. Please note that the guarantee generally covers limited areas of intervention (for example road accidents, joint ownership claims, etc.). Be aware that everything depends on the insurance contract and the company. Do not hesitate to call the legal assistance service of your insurance in order to see with them directly, with regard to the subject of the action, if the costs can be covered. If this is the case, most of the time you just need to send them the invoice, possibly accompanied by the fee agreement, to be reimbursed.
