Abstract
The Code of Obligations of 1933 provided for the most significant regulation of an ordinary mediation agreement in Poland. The current regulations of the Civil Code do not solve the fundamental problems of this institution. An ordinary mediation agreement has not been so far subject of complex considerations in the civil law science; neither the jurisprudence provides for plausible material for analysis. Those reasons justify choice of this subject. The article presents the institution of an ordinary mediation agreement on the basis of the German Civil Code (Bürgerliches Gesetzbuch), the Swiss Law of Obligations (Obligationenrecht), Italian Civil Code (Codice civile). The article also describes an ordinary mediation agreement in the common law systems. Moreover, subject of analysis is an ordinary mediation agreement as set out in the Draft Common Frame of Reference (under mandate contracts). The article reviews as reference sources the Polish as well as English, German and Italian literature and normative acts and judicature.
