Assembling a Property Sale File: Essential Documents

A complete property sale file brings together all the documents that the seller must provide to the buyer and the notary to enable signing of the preliminary sales agreement and then the final deed. In Paris, where the majority of transactions involve units in co-ownerships, this file is more extensive than for a detached house. An incomplete file delays the sale and exposes the seller to claims from the buyer.

Which diagnostics are mandatory to sell in Paris?

Six diagnostics for an apartment: the DPE (energy performance certificate), the asbestos report (buildings with planning permission issued before 1 July 1997), the lead risk assessment (buildings constructed before 1 January 1949), the electrical and gas installation reports (installations over 15 years old), and the environmental risk statement (ERP). Gathered in the technical diagnostic file (DDT) appended to the preliminary sales agreement, they cost 300 to 700 euros for an apartment of 50 to 80 m², borne entirely by the seller.

For Haussmann-era buildings, which are heavily represented in Paris, the lead and asbestos diagnostics are virtually systematic. Their validity periods vary: the DPE is valid for ten years, the lead report is unlimited if no risk is found, the asbestos report is unlimited if negative, and the electrical and gas reports are valid for three years.

Which co-ownership documents must the seller provide?

Since the ALUR law of 2014, they must be delivered no later than the signing of the preliminary agreement, and most are obtained from the property manager (syndic). They are the co-ownership regulations and the descriptive division statement, the co-ownership summary sheet, the general meeting minutes from the last three years, the building maintenance log, the amount of the unit’s current charges, and the amount of approved but not yet called works charges.

The property manager typically charges between 300 and 600 euros to the seller for assembling this file (pre-statement of account and statement of account fees). This cost, regulated by law, includes the statements of account that detail the unit’s financial position within the co-ownership.

Reviewing these documents is essential for the buyer. The general meeting minutes reveal approved works (facade renovation, roof repair, lift upgrades), ongoing disputes, and the general atmosphere of the co-ownership. An experienced apartment hunter identifies warning signs in these documents that an uninformed buyer might miss.

Which legal documents go into the file?

Three at a minimum: the title deed, the Carrez surface area certificate and the most recent property tax notices. The title deed, meaning the previous purchase deed, enables the notary to verify the chain of ownership and the absence of charges or mortgages encumbering the property.

The Carrez surface area certificate, mandatory for any co-ownership unit, certifies the private surface area of the property. If the discrepancy exceeds 5% against the buyer, they can request a proportional price reduction within one year of signing the final deed.

The seller must also provide the most recent property tax notices (taxe foncière and taxe d’habitation, if applicable), invoices for works carried out in the property, and co-ownership insurance certificates.

What should the buyer check in the sale file?

First that it is complete from the very first viewing: that is the clearest sign of the seller’s seriousness. Conversely, the inability to consult general meeting minutes or a refusal to disclose the charges amount should raise concerns, all the more so because a missing annex prevents the 10-day cooling-off period from starting to run.

At Home Select, we systematically request the complete file before recommending a property to our clients. Analysing the property diagnostics, the co-ownership regulations, and the co-ownership accounts is an integral part of our mission. This upfront verification avoids the unpleasant surprises that emerge after the preliminary agreement is signed, when it is often too late to turn back without financial loss.
