Blockchain and real estate leases: concrete future or technological gimmick?

The promise of blockchain for real estate

Blockchain is often presented as a revolutionary technology for real estate: contracts that execute themselves, a tamper-proof land register, transactions without intermediaries. The reality is more nuanced, especially in the Belgian context.

For real estate leases, blockchain promises three things: securing the contract (tamper-proof, timestamped), automating obligations (rent, indexation) via smart contracts, and transparency for all parties. But between the technological promise and practical application in a country where lease registration is done via MyRent, the road is still long.

Smart contracts applied to leases

The concept

A smart contract is a computer programme that executes automatically when predefined conditions are met. Applied to a lease, it could:

• Debit rent automatically on the 1st of each month
• Apply indexation on the anniversary date (by querying an oracle providing the health index)
• Release the rental deposit automatically if no dispute is reported at the end of the lease
• Trigger an automatic formal notice in case of late payment

Credible use cases

The two most credible short-term use cases are timestamping (proving a document existed at a given date) and archiving (guaranteeing a document has not been modified). These are features that qualified electronic signatures already offer, but that blockchain reinforces.

Decentralised registration: an alternative to MyRent?

The current model

In Belgium, lease registration is done with FPS Finance via MyRent. It is a centralised register, managed by the State, which gives the lease enforceability against third parties.

What blockchain could bring

A decentralised lease register on blockchain would offer:

• Immutability: impossible to modify or delete a registered lease
• Transparency: anyone can verify the existence of a lease (if the register is public)
• Automation: registration could be triggered automatically when the smart contract is signed

Why this is not happening soon

• The Belgian legal framework does not recognise blockchain as a registration method
• FPS Finance has no project in this direction
• The question of privacy is critical: a lease contains sensitive personal data (GDPR) that cannot be stored on a public blockchain
• The governance of a property blockchain is complex: who validates, who corrects errors, who handles disputes?

Concrete limitations in Belgium

Adoption

Blockchain requires parties to use digital wallets and understand basic mechanisms. In 2026, fewer than 5% of Belgians own cryptocurrencies, and the proportion that understands smart contracts is infinitely smaller.

Legal framework

Belgian lease law is regionalised and relies on human mechanisms: the justice of the peace settles disputes, FPS registers leases, bailiffs enforce judgements. Blockchain cannot replace these actors.

Cost-benefit ratio

For a landlord managing 3 to 10 properties, existing solutions (electronic signing, MyRent, rental management software) already offer the benefits of digitalisation without the complexity of blockchain.

Realistic horizon for leases in Belgium

For the Belgian landlord in 2026, blockchain is not an operational tool. The priorities remain:

• Sign leases electronically (eID, itsme)
• Register via MyRent within the deadlines
• Use a rental management tool to automate tracking
• Archive documents securely

Blockchain may complement these tools in 10 years, probably transparently (like HTTPS secures your web browsing without you thinking about it). In the meantime, focus on the available and proven tools: digital lease, electronic signing and centralised management.
