Selling a property in Luxembourg requires preparation, and gathering the right documents from the start can help speed up the entire process.

Mandatory documentation:

• Valid identification document (passport or ID card)
• Recent proof of residence
• Deed of sale or property title issued by the notary
• Energy performance certificate (Passeport Énergétique) issued by an authorised technician
• Condominium documents (if applicable), including proof that service charges are up to date

Recommended additional documentation:

• Cadastral plan (required for single-family homes and land, available on the Geoportail cadastral portal or from the local administration)
• Invoices and certificates of works (including guarantees such as the ten-year warranty) for recent renovations or constructions
• Proof of current expenses (electricity, gas, water, insurance, equipment maintenance) to provide greater transparency to the buyer

Having these documents organised from the outset builds trust and helps avoid delays in signing the sales contract.
