Perseverantia voluntatis e furor

Abstract

In Roman law, we find the terms voluntas or consensus with the adjective perseverans, and for example the expression in eadem voluntate perseverare. In fact, there are two kinds voluntas, a first one that could be called "initial", and a second one which implicates the durability, the time that goes on. This leads to a question: what are the consequences when someone, part of a juridical act, became furiosus, whereas his perseverantia voluntatis is longer required?
