  • What is an electronic signature?

    An electronic signature is an electronic indication of a person’s intent to agree to the content of a document or a set of data to which the signature relates. Like its handwritten counterpart in the offline world, an electronic signature is a legal concept capturing the signatory's intent to be bound by the terms of the signed document.

    When to use an electronic signature?

    Electronic signatures can be used in a variety of situations. As their legal effects are equivalent to the ones of handwritten signatures, qualified electronic signatures can be used in any situation, even cross-border, where handwritten signatures are used, such as:

    • Contracts (sales, employment, lease, insurance, etc.)
    • Transactions (e-commerce, online banking, etc.)
    • Administrative procedures (tax declarations, requests for birth certificates, etc.)

    Who provides electronic signatures in Europe?

    Electronic signatures can be used in a variety of situations. As their legal effects are equivalent to the ones of handwritten signatures, qualified electronic signatures can be used in any situation, even cross-border, where handwritten signatures are used, such as:

    Qualified trust services provided in Europe (e.g. issuance of qualified certificates for electronic signatures or seals, qualified timestamping services) are listed in national ‘trusted lists’ in all European Union and European Economic Area member-states.

    Those lists can be accessed through the Trusted List Browser, an online tool provided by the European Commission to ease the process of finding trust services.
