Article 33 of Legal Profession Law

If there is no written agreement on fees, or the written agreement is void, the court that heard the case shall, in the event of disagreement and at the request of the lawyer or client, assess the lawyer’s fees in proportion to the effort he expended and the benefit accruing to the client. The lawyer and the client shall have the right to challenge the assessment order within the fifteen days following service of the order upon him, by summoning his opponent to appear before the court that issued the order. The challenge shall be heard urgently and in chambers (the deliberation chamber). The judgment issued on the challenge shall be final and not subject to appeal. If, however, the disputed fees relate to other work and not to a case heard by the court, the lawyer and the client may bring an ordinary action for their assessment, in which the ordinary rules of the Code of Procedure shall be followed and judgment shall be rendered urgently.
