The thesis will be proved according to which the three-year period of advocate training a priori fulfils the condition of acquiring three years of professional experience related to the performance of legal knowledge requiring activities directly related to the provision of legal assistance by the advocate and makes this in a much wider dimension, enriched with many skills, which is deprived of the person applying for enrolment without a completed application.
