This thesis addresses both the applicability and the measures necessary to implement a dematerialization process in an Asset Management department. But also the impact of this dematerialization as a lever for optimizing the value of the assets in the portfolio managed by the Asset Manager.

It presents the legal framework for dematerialization by taking up the notion of contract and the conditions of validity of the latter. It then discusses the essential framework of electronic signature, the key to the proper functioning of a dematerialization process. Then, several notions no less essential to the proper functioning of the process, such as the confidentiality of data stored in computer format, the admissibility as evidence of dematerialized documents and the proof conventions to be put in place.

It deals more factually with the tools to be implemented in an Asset Management department for the successful implementation of dematerialization and carries out an opportunity study of this implementation. It analyses the impact of dematerialization on the Asset Manager's business.

Finally, this thesis addresses the question of the valorisation of archive spaces whose obsolescence is imminent by proposing valorisation solutions.
