Yes, the Belgian eID allows you to legally sign a lease

Quick answer

The Belgian electronic identity card (eID) allows you to sign a lease with a qualified electronic signature, the highest level under the eIDAS Regulation. This signature has the same legal value as a handwritten signature.

The Belgian eID card contains two electronic certificates: an authentication certificate and a signature certificate. It is the latter that enables you to sign documents with qualified legal value. Article XII.15 of the Belgian Code of Economic Law confirms this equivalence with a handwritten signature.

The eID signature is accepted by all Belgian public services, including the SPF Finances for lease registration. Courts also fully accept documents signed with an eID.

How to sign a lease with eID

To sign a lease using your Belgian eID, you need:

  1. A card reader compatible with the Belgian eID (USB readers cost around 10-15 EUR)
  2. eID middleware installed on your computer (available free from eid.belgium.be)
  3. Your PIN code (the one you set when collecting your eID card)
  4. A signing platform that supports qualified electronic signatures

The process is straightforward:

  • Insert your eID into the card reader
  • Open the document to be signed on the platform
  • Enter your PIN code to confirm your identity
  • The platform generates a qualified signature attached to the document
