Our commitments
Clarté reactivity Humanity
Before your first meeting, gather all relevant documents (contracts, emails, formal notices, identity documents) and draw up a clear timeline of the events: key dates, contact persons, amounts involved. Write down your objectives (amicable resolution, legal action, securing a document) and prepare your questions to clarify fees, deadlines, and chances of success. Finally, list the solutions already considered and remain transparent: the confidentiality of the meeting allows you to share everything so that the lawyer can develop the most effective strategy.
Prevention rather than cure
Long-term client support with a decreasing hourly rate to assist them throughout their construction project with legal issues.
Freliability Transparency Sincerity
DETERMINATION OF FEES
Fees are set according to custom, based on the client's financial situation, the difficulty of the case, the lawyer's expenses, his reputation and his diligence. The lawyer in charge of a case may request fees from his client even if the case is withdrawn from him before its conclusion, to the extent of the work accomplished.
ELEMENTS OF REMUNERATION
The lawyer's remuneration depends, in particular, on each of the following elements in accordance with custom:
- the time spent on the case, the research work, the nature and difficulty of the case,
- the importance of the interests involved,
- the impact of the costs and charges of the firm to which he belongs,
- his reputation, his titles, his seniority, his experience and the specialization he holds,
- the benefits and results obtained for the benefit of the client through his work, as well as the service provided to him, the financial situation of the client.
11.3 PROHIBITED METHODS OF REMUNERATION
Art 11.3 amended and renumbered by DCN n°2015-003, CNB AG of 12-12-2015, Published in the Official Journal by Decision of 14-01-2016-Official Journal February 16, 2016
The lawyer is prohibited from setting his fees by a quota litis pact.
The quota litis pact is an agreement made between the lawyer and his client before a final court decision, which exclusively sets the entirety of his fees based on the legal outcome of the case, whether these fees consist of a sum of money or any other property or value.
The lawyer may only collect fees from his client or from an agent of the latter.
Remuneration for business contributions is prohibited.
