Yes, electronic signatures are valid for Belgian leases

Quick answer

A qualified electronic signature (QES) via itsme or eID has the same legal value as a handwritten signature under the eIDAS Regulation and Belgian law. An electronically signed lease is fully enforceable and can be registered on MyRent.

Belgian law does not require a handwritten signature for a lease to be valid. The Code of Economic Law (Article XII.15) explicitly recognises the legal equivalence of qualified electronic signatures with manuscript signatures.

This means a lease signed electronically via itsme, eID, or any certified qualified signature provider is:

  • Legally binding between the parties
  • Registrable with the SPF Finances via MyRent
  • Admissible as evidence in court proceedings
  • Opposable to third parties once registered

Which type of electronic signature is accepted?

There are three levels of electronic signature under eIDAS:

LevelExamplesValid for a lease?
SimpleClick-to-sign, email confirmationNot recommended — weak legal certainty
Advanced (AES)DocuSign, Adobe Sign with identity verificationAccepted by Belgian courts
Qualified (QES)itsme, Belgian eIDRecommended — full legal equivalence

The qualified electronic signature (QES) offers the strongest legal protection. It is the only level that has automatic legal equivalence with a handwritten signature, without needing to prove its reliability.

BailBelgique tip

BailBelgique integrates itsme and eID signing directly into its lease creation workflow. Both landlord and tenant can sign remotely with a qualified signature.

Registration and court validity

An electronically signed lease can be registered via MyRent just like a traditionally signed lease. The SPF Finances accepts PDF files with embedded electronic signatures.

In court proceedings, a lease bearing a qualified electronic signature cannot be challenged on the grounds of its electronic form. The judge must treat it as equivalent to a handwritten signature. For advanced electronic signatures (AES), the court may request additional proof of the signatory’s identity.

The inventory of fixtures can also be signed electronically using the same methods.
