Electronic signature and electronic seal for Monegasque professionals issued by the Direction de l’Expansion Economique (DEE)

Professional electronic certificates (corresponding to a digital identity card (1)) enabling an electronic signature (natural person representing the legal entity) or an electronic seal (on behalf of the legal entity) to be affixed are issued by the State of Monaco in its capacity as a trusted third party, and delivered to companies registered in the Monegasque RCI (2) by the Direction de l’Expansion Économique (DEE – Economic Development Department) in its capacity as Registration Authority.

These are only intended for professional documents (contract, order form or delivery form, invoice, commitment document, declaration, pay slip…), excluding personal documents.

Electronic certificates are valid for 3 years from the date of issue (renewable before their expiry date). The fee of €120 (three-yearly amount) collected for the benefit of the Treasury must be paid as from the filing of the request for the issuance of an electronic signature or seal.

Our law firm can act as a certification agent (mandataire de certification) in order to manage your company’s fleet of electronic certificates during their life cycle: registration process including the control of the file and the identity of the holder, renewal and revocation process with the DEE.  

As a reminder, the Civil Code guarantees that digital documents (provided that the person from whom they originate can be duly identified and that they are drawn up and stored in conditions that guarantee their integrity) and paper documents have equivalent probative value. (3)

The electronic signature is the essential tool for digital documents, just as the handwritten signature is for paper documents. Reserved for natural persons, it makes it possible to identify the signatory of a document and guarantee its integrity, for the signatory to express his or her consent, and to carry out administrative or commercial acts at a distance. The use of the electronic signature is an option for Monegasque professionals, who retain the possibility of signing their documents by hand.

The electronic seal is the more elaborate digital version of the company stamp. It allows to prove that an electronic document has been issued by a legal person by guaranteeing the origin and integrity of the document, but unlike the electronic signature for natural persons, it does not allow the legal person to express its consent. The use of an electronic seal is an option for companies, in order to seal and reinforce the legal value of their dematerialised business documents, by providing the additional guarantee that they have not been modified.
