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.
Mandatory technical diagnostics
The technical diagnostic file (DDT) must be appended to the preliminary sales agreement. In Paris, the mandatory diagnostics for an apartment are 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 installation report (if the installation is over 15 years old), the gas installation report (if over 15 years old), and the environmental risk statement (ERP).
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.
The total cost of diagnostics for a Parisian apartment of 50 to 80 m2 is between 300 and 700 euros, borne entirely by the seller.
Co-ownership documents
Since the ALUR law of 2014, the seller must provide a set of co-ownership-related documents, most of which are obtained from the property manager (syndic). The main documents 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.
Title deed and legal documents
The seller must provide their title deed (previous purchase deed), which 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 fonciere and taxe d’habitation, if applicable), invoices for works carried out in the property, and co-ownership insurance certificates.
The buyer’s perspective
For the buyer, the completeness of the sale file determines the quality of their decision-making. A complete file delivered from the first viewing is a 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.
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.

Frequently asked questions
How long does it take to assemble a complete sale file in Paris?
On average, two to four weeks. Technical diagnostics are carried out in a few days, but obtaining co-ownership documents (general meeting minutes, maintenance log, summary sheet) can take longer if the property manager is not responsive. Requesting these documents as soon as the property goes on the market avoids delaying the preliminary agreement.
Who pays for the mandatory property diagnostics?
The seller. The technical diagnostics (DPE, asbestos, lead, electrical, gas, termites, ERP) are entirely at their expense. The average cost for an apartment in Paris is between 300 and 700 euros depending on the size and number of diagnostics required.
Can a buyer refuse to sign the preliminary agreement if the file is incomplete?
Yes, and it is even advisable. The ALUR law requires the delivery of co-ownership documents no later than at the signing of the preliminary agreement. The absence of these documents can invalidate the buyer's cooling-off period, effectively postponing the start of the 10 days. An incomplete file is a warning sign that a property hunter spots immediately.
