Selling a property: which documents are mandatory?

Selling a property: which documents are mandatory?

Are you a homeowner thinking of selling your house or flat? Be aware that this is not something you can improvise. It is essential to put together a complete and legally valid sale file, otherwise the transaction could be jeopardised. In Liège, the estate agency BIV Immobilier gives you a clear overview of the documents you need to gather to sell with complete peace of mind and in compliance with the rules in force.

The title deed

As its name suggests, the title deed is the document that proves you really are the owner of the house or flat in question. It corresponds to the notarial deed.

The energy performance certificate (EPC – PEB)

This document shows your property’s energy rating, in other words its level of energy consumption. It must be included in the sale listing and be drawn up by an approved EPC (PEB) assessor. You can easily find one in your region: Brussels, Wallonia, Flanders.

The soil certificate

This certificate is issued by the regional administration (Brussels Environment, BDES, OVAM) and sets out detailed information on the condition of the soil. In particular, it indicates whether the soil is polluted, has been remediated or is being remediated.

The electrical installation inspection report

This document certifies that the electrical installation complies with the standards in force. It must be drawn up by an approved inspector. If the installation does not comply, the sale can still go ahead, but the buyer will have to carry out the work needed to bring it into compliance within 12 or 18 months of signing the deed, depending on whether the installation dates from after or before October 1981.

Planning information (RU)

Issued by the municipal administration, the planning information (renseignements urbanistiques) brings together all the information relating to the property: intended use, permits issued, planning certificates, cadastral data and other information relevant to the sale.

The post-intervention file (DIU)

The DIU lists all the work carried out in your house or flat since 1 May 2001. It must be carefully kept up to date and include the quotes, invoices, any plans and photos of the work.

Specific cases

  • If the property is let

You must provide the documents relating to the lease (contract, inventory of fixtures, proof of deposit of the rental guarantee, etc.). The new owners will have to respect the terms of the current lease.

  • If the property is part of a co-ownership

You must hand over the minutes of the general meetings (GMs) for the last 3 years, the co-ownership regulations and the financial information: the amounts in the working capital fund and the reserve fund, as well as any arrears payable by the seller. You can obtain these from your property manager (syndic).

  • If you have oil-fired heating

If your tank has a capacity of 3,000 litres or more, it must be inspected by an approved heating engineer
who will give you a certificate.
