Essential documents to keep

Quick answer

Every landlord should maintain a complete file for each tenancy, containing: signed lease, registration proof, inventory of fixtures, deposit certificate, rent receipts, correspondence, insurance certificates, and mandatory reports (EPC, electrical installation). These documents are essential evidence in case of disputes.

A comprehensive rental file should include:

  1. Lease and addenda: original signed copies, any amendments
  2. Registration proof: confirmation from the FPS Finance
  3. Inventory of fixtures: entry and exit, with photos
  4. Deposit certificate: bank account details, blocked account confirmation
  5. Rent receipts: monthly payment records
  6. Correspondence: formal notices, repair requests, all important letters
  7. Insurance: landlord liability, building insurance
  8. Certificates: EPC, electrical installation report, gas conformity
  9. Tax documents: rental income declarations, property tax notices

Organising your files

Recommended structure

Create one folder per property, with sub-folders per tenancy. Within each tenancy folder: lease, inventory, deposit, correspondence, payments, certificates. Use consistent naming conventions with dates.

Suggested folder structure:

Warning

Belgian law requires landlords to keep rental documents for at least 5 years after the end of the tenancy (general limitation period for contractual claims). Tax-related documents should be kept for 7 years.

Digital versus physical filing

Both approaches are legally valid in Belgium. Digital documents have the same probative value as physical ones, provided they meet certain conditions:

  • Digital signatures: valid under the eIDAS Regulation
  • Scanned copies: admissible as evidence, though originals have stronger probative value
  • Cloud storage: recommended for backups, but ensure data protection compliance (GDPR)
  • Email correspondence: has probative value as a written document

The advantages of digital filing are clear: accessibility from anywhere, automatic backups, easy sharing with tenants or property managers, and space savings. This is particularly valuable for remote property management.

However, it is advisable to keep original signed leases and registered documents in physical form as well.
