Another characteristic of this school is that its teachers do not receive a salary or monetary compensation whatsoever, which is why students only make a symbolic payment used to cover the school expenses.

The motto for Escuela Libre de Derecho is "Ius neque inflecti gratia, Neque perfringi potentia, Neque adulterari pecunia debet", which traduced from Latin means "law cannot be influenced by favor, seduced by power nor adulterated by pecuniary favor".

The building of the Escuela Libre de Derecho has an access from Doctor José María Vértiz street and another one from Arcos de Belén Avenue; said access has a hall with red walls that has transcribed in golden letters the article 6 of the schools regulation that states: "the order and discipline of the School are entrusted to the honor of its students and its teachers", emphasizing that the responsibility of the order inside and outside of the Institution rests in its student body and teachers, who always have in consideration that in Escuela Libre de Derecho everyone act in good faith.

This system is based in having a maximum number of courses a student can fail each year, as long it does not exceeds five courses, failing a sixth course would be cause for definitive discharge from the Institution; the ordinary time to conclude studies in this Institution and according with its study plan is of five years, but it cannot be extended by more than two years, since it would cause definitive discharge of the student.

The grades assigned by the examining jury in each course are unappealable.
