A contract of brokerage is a contract whereby one of the parties agrees to inform the other party of the occasion to constitute a contract, or to act as intermediary for the conclusion of a contract, and such other party agrees to pay him remuneration.

Remuneration is deemed to have been agreed upon, if from the circumstances the broker is not to apply the information for the conclusion of the contract or to act as an intermediary for it without remuneration.
If the amount of the remuneration is not specified, it shall be paid according to the tariff. If there is not a tariff, the remuneration shall be paid according to custom.

The broker is bound to accurately to each party report the circumstances of the proposed transaction, so far as he knows them. He shall not act as intermediary for a person who is notoriously insolvent or whom he knows to have no capacity to enter into the proposed contract.
A business broker has duty of investigation about the circumstances of the proposed transaction and the solvency or capacity of each party to enter into the proposed contract.

The broker is entitled to his remuneration only if the contract is constituted through his intermediary or due to the information supplied by him.
When the contract is constituted under a suspenseful condition, the broker shall not claim the remuneration until the condition is fulfilled.

The broker is entitled to claim reimbursement for expenses incurred by him only if such reimbursement has been agreed upon.
The provisions of the preceding paragraph shall be applied even if no contract is constituted after the broker has supplied the information or acted as an intermediary.

Unless otherwise provided for by contract or by custom, each party to the contract shall bear an equal part of the remuneration to which the broker is entitled for having acted as intermediary.

The broker forfeits his rights to remuneration and to reimbursement of expenses if he acts in the interest of the other party contrary to his obligations to the principal, or if he accepts from such other party advantages under such circumstances as violating the rules of good faith.

If the agreed remuneration is not proportionate to the actual value of the services rendered by the broker to such an extent that unfairness of the transaction appears, the court may at its discretion, on the application of the person who is responsible for the remuneration, reduce it to a reasonable amount. But no claim shall be made for the return of the remuneration already paid.

An agreement promising remuneration for matrimonial brokerage, the claim of remuneration is not enforceable.

A broker has no authority to make or to receive on behalf of the parties prestations concerning the contract entered into through his intermediary.

The broker is bound, if so instructed by one of the parties, not to disclose the name of such party or of such party's firm to the other party in the contract.
When the broker does not disclose to one of the parties the name of the other party or of the other party's firm, he is personally liable for the performance of the obligations of such other party resulting from the contract and he has authority to receive prestations on behalf on such party.
