The Sales Agreement in Luxembourg: Complete Guide 2026

The sales agreement (compromis de vente) is the crucial step that legally binds seller and buyer in a property transaction in Luxembourg. Unlike a simple purchase offer, it creates legal obligations for both parties.

What is a Sales Agreement in Luxembourg?

The sales agreement is a bilateral contract whereby the seller commits to sell and the buyer commits to purchase a property at an agreed price. In Luxembourg, it has the force of a sale from the moment of signing, subject to conditions precedent.

• Identity of the parties (seller and buyer)
• Precise description of the property (address, cadastral reference, surface area)
• Sale price and payment terms
• Any conditions precedent
• Deadline for signing the notarial deed

Difference Between Sales Agreement and Notarial Deed

The sales agreement is a private contract between parties, while the notarial deed is drawn up and signed before a notary. In Luxembourg, only the notarial deed enables official property transfer and land registry registration.

Essential Clauses

Conditions Precedent

The most common conditions precedent in Luxembourg:

• Mortgage approval: the buyer typically has 4 to 6 weeks to obtain financing
• No easements: verification that no easements prevent normal use
• Planning compliance: the property complies with planning regulations
• No mortgages: the property is free of encumbrances

The 10% Deposit

In Luxembourg, the buyer traditionally pays a 10% deposit upon signing the sales agreement. This sum is held by the notary in an escrow account.

Completion Deadline

The agreement sets a maximum deadline for signing the notarial deed, generally between 3 and 6 months.

Role of the Notary

Although the agreement can be signed privately, it is strongly recommended to involve a notary. The notary verifies the legal status of the property and protects both parties' interests.

FAQ

Can you withdraw after signing a sales agreement in Luxembourg?

Unlike France, there is no legal cooling-off period in Luxembourg for property sales between private parties. Only the non-fulfillment of a condition precedent allows cancellation without penalty.

What happens if the buyer cannot obtain a mortgage?

If the agreement contains a mortgage condition precedent and the bank refuses financing, the agreement is voided. The buyer receives their full deposit back.
