In order to answer this question and in the absence of any specific provisions in the Labour Code, it is necessary to rely on what the parties agreed in the employment contract or, where applicable, the collective agreement.
If the employment contract or the collective agreement contains a clause granting an allowance for travel costs, then the employee will be entitled to payment of that allowance if he travels on behalf of the employer and at the employer’s request, using a private vehicle belonging to the employee.
In the absence of a clause providing for an allowance for travel costs, the employee may not claim payment of such an allowance.
Pursuant to Article 1315 of the Civil Code: “Any person calling for the performance of an obligation must prove its existence”, so that, if an employer challenges the obligation to compensate for an employee’s travel costs, it is incumbent upon the employee to produce evidence of that obligation.
