How long should you keep lease documents?

Quick answer

Keep all leases and related rental documents for at least 10 years after the end of the lease. This corresponds to the general limitation period for personal actions under Belgian civil law (article 2262bis of the Civil Code). Digital archiving with timestamping is the safest approach.

The 10-year rule covers the vast majority of potential claims: unpaid rent, deposit disputes, damage claims, and contractual liability. Some tax-related documents must be kept even longer (up to 7 years for tax purposes, overlapping with the civil deadline).

In practice, it is strongly recommended to keep documents for the entire duration of the lease plus 10 years after its termination, to be fully protected against late claims.

Best practices for archiving

The most reliable method is a combination of physical and digital archiving:

  1. Scan all documents in PDF format (lease, inventories, registered letters, rent receipts)
  2. Use a secure cloud with automatic backup and timestamping
  3. Organise by property and by tenant to retrieve documents quickly
  4. Keep proof of registered letters (sending receipts, tracking numbers)
  5. Store originals in a safe or fireproof cabinet for critical documents

Which documents to keep

Beyond the lease itself, several categories of documents should be archived:

  • The lease and all amendments or addenda
  • Entry and exit inventories (critical for deposit disputes)
  • Rent receipts and payment records
  • Registered letters (notices, demands, termination letters)
  • Works and repair invoices (to prove maintenance was performed)
  • Insurance certificates (tenant’s liability insurance)
  • EPC certificates and compliance documents

If a dispute arises years after the lease ends, these documents may be the only evidence available. Without them, proving your case before the justice of the peace becomes significantly harder.
