8 Documents for What Documents to Sell a Property

You've found a buyer, but the sale is already losing momentum. The DPE has expired, the title deed is incomplete, or the copropriété records haven't arrived from the syndic. The buyer is ready to proceed, yet the notary can't prepare the file without the right documents.

That's why the practical answer to what documents to sell a property isn't one universal list. The required file depends on the building's age, its gas and electrical installations, its location, its energy rating, its ownership history, and whether it belongs to a copropriété or has been rented out. The seller pays for the required property diagnostics, and the documents form part of the legal information package given to the buyer.

This guide follows the preparation workflow rather than presenting a loose pile of paperwork. You'll see how to prove ownership, arrange the main diagnostics, check validity periods, identify the right professionals, budget for the work, and spot property-specific variations before signing. For a broader comparison with another seller disclosure system, see this California seller disclosure guide.

1. Energy Performance Diagnostic DPE

Before publishing the property, prepare its Energy Performance Diagnostic, known as the DPE. This report evaluates energy use and environmental impact, then places the home on a scale from A to G. A indicates the most efficient performance. For a buyer, the rating works like a first filter: it helps compare properties and anticipate possible heating or insulation work.

Book a certified, insured diagnostician and gather the information needed for an accurate report. Check the seller's name, address, floor area, heating and hot-water systems, and greenhouse-gas rating as soon as you receive it. Keep the complete document, not only the page displaying the letter. The stated validity period is 10 years, but ask the diagnostician or notary to confirm whether a newer report is required for your transaction. The French public service explains the DPE and its validity rules.

Practical rule: Before using the rating in an advertisement, confirm that the report describes the property, equipment, and floor area you are actually selling.

How to prepare a weak rating

A low rating may affect buyer interest, negotiation, and the sale timetable. Treat the recommendations as a preparation list. Collect quotations, invoices, and completion records for work already planned or carried out. Present those documents as evidence of the property's situation, without promising a future rating that has not yet been assessed.

The DPE forms part of the DDT, or Technical Diagnostic File. This is the technical information file provided to the buyer. The notaries' guidance explains that it may contain up to 12 documents, depending on the property and its circumstances. The notaries' guidance on technical property diagnostics also indicates that an energy audit can be required for homes rated F or G under the stated rules.

For an agent, copy the same DPE details into the listing, brochure, and property description. Clear information reduces inconsistencies when the file passes from the seller to the buyer and notary.

2. Electrical Compliance Certificate Consuel

The Consuel certificate and the electrical diagnostic serve two different needs. The Consuel generally certifies that a new or extensively renovated installation has been inspected according to applicable technical requirements, including the NF C 15-100 standard. For an installation over 15 years old, the sales file may also require an electrical safety diagnostic.

Start by searching for the original certificate in the renovation file. Also check the electrical panel, invoices, completion reports, and documents provided by the electrician. If the certificate is missing, contact the professional who worked on it to see if a duplicate exists, then ask the notary what verification is suitable for the sale.

The indicative cost provided for a Consuel procedure is €150 to €300, with a possible timeframe of four to six weeks. Confirm these details before placing any order, as the amount and schedule depend on the installation and the procedure chosen.

Correct anomalies before passing to the notary

A certificate or report describes the state of the installation at the time of inspection. It does not finance repairs and does not automatically confirm the compliance of every subsequent modification. A qualified electrician must carry out corrective work. Then keep the quote, invoice, and end-of-work documents in the property file.

A recent renovation is not enough to establish the current situation. Compare the scope of the work with the installation in place and ensure that the certificate covers the relevant elements.

• Search for the original file: check titles, renovation binders, invoices, and previous exchanges with the notary.
• Contact the electrician promptly: ask if the existing certificate is sufficient or if a new inspection is necessary.
• Allow for technical margins: request the document before putting it on the market if the status of the installation remains uncertain.
• Present the result accurately: a certificate number can support the file, but it does not replace the report itself.

3. Risk and Pollution State ERP

The Risk and Pollution State, or ERP, informs the buyer of risks related to the property's address. Depending on its location, it may present natural and technological risks, soil pollution, seismic information, and other data required by regulation.

Prepare this document based on the exact address, like an identity sheet for the land. Consult official information, note the date of establishment of the ERP, and file it with the other diagnostics in the sales dossier. A property located in a flood zone or near an industrial site requires careful verification of consistency between the advertisement, the preliminary contract, and the final file.

The seller must provide an updated ERP. Its standard validity is six months. Therefore, compare its date with the one scheduled for the signing of the deed. The document must also be transmitted early enough for the buyer to review it. The provided preparation guidelines foresee a handover at least seven days before the signing of the deed. Check the current official requirements on the French public service website before using an old form or report.

Verify the ERP before signing

A risk indicated in the ERP does not automatically mean that the property is uninhabitable. It describes a situation related to the sector. The buyer can thus ask questions and make their decision with the same information as the notary.

Keep the official document. A simplified wording in the advertisement does not replace it. If the property is rural or technically difficult to understand, ask the notary or a qualified professional to explain the practical consequences of the mentioned risks.

The ERP is not a commercial obstacle. It helps the buyer assess the address and leaves a clear trace in the sales file.

4. Asbestos Diagnostic for Older Buildings

Before booking any inspection, verify the building's regulatory history. The asbestos diagnostic concerns buildings whose planning permission was issued before 1 July 1997. This threshold depends on the official history of the property, not only on the seller's estimate of its completion date. Check the title file, planning records, or notary's documents for an older house or flat.

A certified diagnostician examines materials that may contain asbestos and records their condition in the report. Removal or treatment requires a separate specialist company. Depending on the material and its condition, the report may recommend monitoring, further assessment, or remedial work.

The supplied budgeting guide places this diagnostic at €150 to €300. The final amount depends on the property and the scope of the inspection. Check the report date and conclusion because validity depends on the result and report type. The guide to selling a house can also help organise the wider preparation file.

Prepare the asbestos file

A property from the 1970s, 1980s, or 1990s deserves early review because asbestos-containing materials may be present in several areas. Use the report's exact wording. Describe the property as “asbestos-free” only when the document supports that conclusion.

• Confirm the construction history: Establish whether the pre-1997 threshold applies before commissioning the diagnostic.
• Book the inspection early: Allow time to access roof spaces, service areas, outbuildings, and shared parts when relevant.
• Check the professional: Use a certified diagnostician and keep the inspection details with the report.
• Keep the complete document: File the conclusions, supporting observations, and recommendations in the sale dossier.
• Request a specialist estimate if needed: A quotation shows the buyer what treatment could involve without suggesting that work has already been completed.

The report should remain available alongside the other diagnostics before signing. A negative result can reassure buyers when presented accurately. If asbestos is identified, disclose it and gather any related assessments, quotations, work orders, or invoices so the buyer can understand the current situation.

5. Lead Diagnostic for Buildings Before 1949

A property in Paris dating from 1920, for example, should prompt an early check of its construction date and existing diagnostic file. The Lead Exposure Risk Diagnostic, known as the CREP, applies when the building's planning permission was issued before 1 January 1949. It examines lead, especially in painted surfaces, so the buyer can assess potential exposure from deteriorating paint.

Start by confirming the building date, then book a qualified property diagnostician. Keep the report available from the beginning of marketing. Families with young children may examine this document closely, and late disclosure can create concern during negotiations.

The supplied budgeting reference is €100 to €200. The validity period varies according to the presence of lead and the report's conclusion. Check both the issue date and the result instead of applying one expiry rule. The French public service's property diagnostic information sets out the relevant lead threshold and validity approach.

Make the result usable

The CREP report documents current conditions. A remediation plan requires separate specialist assessment and documentation. If lead is identified, ask a qualified professional to examine the affected surfaces and advise on safe treatment. Keep quotations, work orders, invoices, and completion evidence. Describe the issue as resolved only when completed work is documented.

Prepare these three items before negotiations advance:

1. Building-date evidence, showing why the CREP applies.
2. The complete CREP, including its conclusion and recommendations.
3. A practical response, such as a specialist assessment or documented treatment plan when appropriate.

A negative result may appear in marketing material if the wording follows the report. A positive result should be disclosed clearly and supported by the available records. This gives the buyer information to consider during the decision, rather than leaving the issue to emerge during a late notarial review.

6. Termite and Other Pest Diagnostic

Before ordering this diagnostic, verify whether the property's commune is in an area covered by a local termite order. The requirement applies according to location, not automatically to every French property. Ask the mairie or the notary to confirm the address. Areas such as Aquitaine and Charente require particular attention, although the exact commune remains decisive. The French public service explains the location-based nature and validity of termite reports.

The report may also cover other wood-boring insects when the applicable inspection requires it. A qualified diagnostician examines accessible parts of the property and records the condition observed on the inspection date. Treat the report like a dated snapshot, not a permanent guarantee about the building.

The supplied cost guide is €100 to €150. The standard validity reference for termite information is six months, so check the report's issue date before signing. A report from an earlier transaction may no longer be usable.

Turn findings into an organised file

If termites are reported, contact a specialist treatment company for a quote. Gather previous treatment contracts, monitoring records, guarantees, and invoices. Put these documents in date order so the buyer can distinguish a current finding from earlier treatment.

Accurate wording matters: “Negative termite report” and “treated property” describe different situations. Use the wording supported by the current report and treatment records.

Treatment history can answer practical questions, but it does not justify claiming that the building is permanently pest-free. Disclose the current report and explain what the available records show. Avoid assurances that go beyond the diagnostician's conclusion.

Complete the preparation in this order:

• Confirm the commune: Ask the mairie or notary whether the area is designated.
• Order the report when required: Check that its date will remain valid through the sale process.
• Gather treatment evidence: Keep contracts, monitoring records, guarantees, and invoices together.
• Describe the result precisely: Separate an observed infestation, a treatment history, and a negative current report.

7. Property Ownership Certificate and Title Deed

Start the seller's file with proof of ownership. The title deed identifies the owner, the house, flat, parcel, or lot concerned, and the rights attached to it. It may mention easements, charges, or other restrictions that influence the sale. The notary verifies the deed and completes the legal checks. Finding the available records early can shorten the preparation.

For a purchase, locate the notarial deed signed at the time of acquisition. For an inheritance, gather the documents showing how the succession transferred the rights. The notary may request a succession file, an acte de notoriété, which formally identifies the heirs, or other supporting records. Holding the keys does not establish a complete ownership history.

Read the deed carefully and compare it with the property as it exists:

• Seller identity: Check names, marital status, and ownership shares.
• Property description: Confirm the address, parcel references, lot number, and stated boundaries.
• Rights and restrictions: Look for rights of way, easements, covenants, and access arrangements.
• Security interests: Report known mortgages or charges to the notary.
• Completeness: Locate every page, annex, plan, and document mentioned in the deed.

Let the notary review the history early

An inherited property may require more documents than a property bought by its current seller. Several owners, an unresolved succession, or an indivision arrangement can mean additional signatures and evidence. Indivision means that several people hold rights in the same property. Identify every person whose consent or signature may be needed.

A right-of-way easement also deserves precise attention. Describe how it affects access, parking, gardens, or services, and make the related document available. This prevents the deed, the diagnostics, and the preliminary contract from describing different rights.

The wider seller file may contain identity and civil-status documents, the title deed, the DDT, plans, a precise property description, and evidence of works completed during the relevant period. This notarial list of documents to provide shows how ownership, works, and rented-property records fit into the transaction file.

Before signing the preliminary contract, compare its property description with the deed and diagnostics. A model promesse de vente can help identify the information to assemble. The notary should draft or validate the legal document.

8. Gas Diagnostic for Installations Over 15 Years Old

Start by checking the age of the gas installation. The gas diagnostic concerns a natural-gas or propane installation more than 15 years old. A diagnostician examines the visible pipework, appliances, ventilation, and possible leaks. The report records the condition observed on the inspection date, much like a technical snapshot for the buyer.

For example, a home whose gas-heating system was installed in 1995 should be assessed before the sale advances. A ventilation defect can require prompt attention. Its presence may also influence the buyer's decision or lead to a request to renegotiate.

The supplied cost guide is €150 to €250, and the standard validity reference is three years. The official French public service page lists the age threshold, diagnostic scope, and validity rules. Check the report date, address, and property description before adding it to the sale file.

Separate inspection from repair

The diagnostician reports the condition. A qualified heating or gas professional handles repairs, replacement, or compliance work. Booking an appointment does not mean that a defect has been corrected. Keep the quotation, invoice, and completion certificate so the notary and buyer can distinguish planned work from completed work.

If the installation's age is unclear, arrange the inspection before accepting an offer. This leaves time to investigate a ventilation issue before the buyer has organised financing and formed firm expectations.

Use precise wording in the listing. Identify the type of gas installation inspected, state the report date when useful, and present significant findings consistently. The report is one part of the seller's preparation workflow: verify the installation, check the document's validity, confirm the issuing professional, and record any related costs before signing. That preparation gives the buyer a clear basis for deciding whether the property suits their needs.

Turn the Checklist Into a Delay-Proof Sale

The best answer to what documents to sell a property is a preparation system built around the property, not a copied checklist. Ask the notary for the complete seller-file requirements at the start. Then identify the building's age, the age of the gas and electrical installations, the energy class, the location-based risks, and the ownership history.

Order the short-validity documents at the right point in the workflow. An ERP and termite report may need attention close to the transaction because each has a six-month reference period. The DPE has a stated 10-year validity, while gas and electrical requirements depend on installation age. The notary can confirm whether a report remains usable for the planned preliminary contract and final deed.

Create one digital folder with clear file names. For every diagnostic, record:

• Document type: DPE, ERP, asbestos, lead, termite, gas, or electrical.
• Issue date: The date shown on the report.
• Expiry information: The stated validity or the condition affecting validity.
• Property details: Address, building, flat, lot, or parcel references.
• Professional details: The diagnostician's identity, certification information, and insurance details where supplied.

Then add the ownership and transaction records. Include the title deed, identity and civil-status documents, plans, the recent property tax notice, and evidence for works completed during the relevant period. Permits, invoices, insurance, and guarantees can help the notary verify the property's history. A rented property needs its own lease chain, including the lease, entry inventory, recent rent receipts, and notices connected with the sale or termination of the tenancy.

Check the property profile before listing

A flat in a copropriété may require documents about the building, the lot, the rules, charges, and the syndic. A property in a lotissement can require documents connected with that development. Recent building work may require planning permissions, completion records, invoices, and insurance evidence. An inherited property may need succession documents and confirmation of every owner's rights.

New builds and properties with recent renovations also deserve a separate check for completion, guarantees, insurance, and planning records. Don't assume that the eight core documents replace the wider notarial file. The official notary guidance describes the DDT as a legal bundle whose contents vary with the property's type, age, location, and circumstances. This explanation of when and how property diagnostics are required is useful when a generic online list doesn't answer your situation.

Send the complete folder to the notary early. Verify that names, addresses, surfaces, lot numbers, and dates match across the documents. If a report will expire before signing, renew it before the deadline becomes a negotiation problem.
