This document is intended to provide all trial attorneys with a jurisprudential compilation of evidential aspects that differentiate commercial agency contracts from any other type, like supplies or distribution ones. To aim for this, at first, the essential and also most controversial elements of agency contracts will be listed and subsequently briefly defined. After this, different mechanisms will be established to work as evidence for any judge that has to solve the battle where its determined whether such contracts were well set up or not. In parallel, sentences that have resolved several hypothesis that turned out to be controversial will be examined as well as some specific cases that will work as reference to determine different lines of case-law that have been created around those.
