The ius honorarium is a term originating from Latin roots, whose meaning describes that series of rules, precepts or norms provided in the Edicts of the magistrates and mainly of the Praetors in Ancient Rome. That is to say that they were laws that were developed in edicts published by the praetors during the Republic and the beginning of the Empire, to help, complete or modify the existing rules or procedures of ius civile. It was completed in the 2nd century AD in the Edictum Perpetuum. The procedures developed by the praetors (the form system) were superseded in the 3rd century by cognitons.
The ius honorarium was established in Ancient Rome, created according to the Roman jurisconsult Papiano or Aemilius Papinianus in Latin, with the purpose of correcting, helping or supplementing the ius civile. And according to Papiano, civil law is the one that originates other sources compared to honorary or praetorian law, we speak of sources such as imperial constitutions, plebiscites, senateconsults, laws and interpretations of jurisconsults.
In classical times, the nucleus of norms that make up the ius civile occupies a position of supremacy as regards the ius honorarium, which is subordinate and complementary. Then for the post-classical period the fold of the ordinances disappears, and both civil and honorary law form a single system cataloged as Roman Civil Law.
Therefore, the honorary right begins to reform or cement the existing civil law in Ancient Rome, and ends up doing so in this post-classical era marked with the character Salvio Juliano for the year 129 AD.
