Extrajudicial conciliation in Colombia exhibits unique characteristics concerning the diverse parties eligible for participation, stemming directly from regulations governing this alternative conflict resolution method. This work of research aims to employ critical analysis, bibliographic review and documentary examination to identify the specific features of the process that directly or indirectly influence the eligibility of parties to engage in the conciliation hearing within the judicial process. It is evident that the presence of conflicting parties at the conciliation hearing is obligatory. Additionally, legal representatives and those summoned as guarantors may also attend. However, unofficial agents possess limited authority in the process, lacking the necessary rights to ensure their involvement in the conciliation hearing.
