1. Where the broker's fee is not fixed in the Law or the agreement, it shall be determined according to the customs. In the absence of a custom, the judge shall estimate it according to the transaction value, the effort exerted by the broker and the time spent by him while carrying out the task assigned to him. 2. The judge may reduce the fee agreed if it is not commensurate with the nature of the transaction and the effort exerted by the broker. No reduction may be decided if the fee was agreed upon or if it was willingly paid by the customer after the conclusion of the contract brokered by the broker.
