The person who gives the mandate, the mandator, must cooperate with the person who accepts it, the mandatary, and at the mandatary’s request must:
- advance any sums required to execute the mandate;
- reimburse the mandatary for all reasonable expenses incurred in executing the mandate;
- pay any remuneration to which he or she is entitled.
If the mandatary had the car’s transmission replaced but was unable to complete the sale, the mandator would still have to reimburse the mandatary for the cost of the repairs, plus interest.
Interest is calculated from the day on which the money was disbursed.
