Lawyer's must inform their clients how their fees are structured (Article 11 of the National Bar Rules), which implicitly requires transparency.
This transparency can be embodied by a fee agreement, which express the agreement between lawyers and their clients on how their compensation is calculated.
This agreement is compulsory for divorce cases since January 1st 2013.
Where no agreement exists, a lawyer's compensation is set according to standard practice, in other words with regard to the client's financial situation, complexity of the case, the costs incurred by the lawyer and the lawyer's reputation and duties. Setting fees based on the result alone is prohibited.
