The origin of the institute of procedural substitution in Bulgarian law

The article strives to analyse the origin of the institute of procedural substitution (for the lack of a better term) in Bulgaria through historic overview, starting with the law of Ancient Rome, going through ius commune and finishing with the contemporary legal regime. From a procedural standpoint, the conclusion is that the institute came into being at the end of the XIX and beginning of the XX century. While manifestations of procedural substitution can be found in the Roman law, this is not an indication of a formulation of the legal institute itself.
