Without prejudice to the exercise resulting from the legal subrogation of the guarantee fund in the rights which the creditor of the compensation has against the tortfeasor or the insurer, the guarantee fund shall also be entitled to claim from the debtor of the compensation : on the one hand, interest calculated at the legal rate from the date of payment of the compensation where this has been fixed by a court, or from the date of the formal notice sent by the guarantee fund where the compensation has been fixed by a settlement; on the other hand, a fixed allowance intended to cover the costs of recovery, the amount of which is fixed on the basis determined by a decree issued on the proposal of the Minister for the Budget.
Where applicable, the guarantee fund also recovers from the debtor of the compensation the contribution referred to in 4° of article R. 421-27.
If the person responsible for the damage intends to exercise the right to dispute provided for in article L. 421-3, he must bring his action before the competent court within three months of the formal demand for reimbursement sent by the guarantee fund.
The formal notice provided for in the above paragraphs is sent by the fund by registered letter with acknowledgement of receipt.
