The retainer allows the client to have a lead Solicitor at a reasonable price. A Solicitor that becomes a part of the client’s particular, professional or commercial activity, which gives a general service but can act specifically in every case. In areas of civil, commercial, corporate, criminal, administrative, labour law, etc., having a Solicitor on a retainer allows the client to have a highly qualified and specialized person always on call for a reasonable monthly fee. For the Lawyer, this allows him to apply an economic scale to the clients’ proceedings, which gives more efficiency with an important reduction in the time invested. This merger is very positive for both parties, also economically, efficiency and makes the client more competitive. The base principal is: “It is not business for this Lawyer, if it is not business for the client”.
