Authentic Deed of Sale: The Complete Guide

The authentic deed of sale is the notarized document that finalizes the transfer of ownership of a property. Signed at the notaire’s office, it typically occurs 2 to 3 months after the preliminary contract and grants the buyer full ownership of the property along with the handover of keys.

Introduction

For any Parisian buyer, signing the authentic deed represents the culmination of several months of searching, negotiation and administrative steps. In 2026, with approximately 35,000 property transactions per year in Paris, notaire offices handle a considerable volume of files. Timelines can vary and the documents to provide are numerous.

Since 2011, our apartment hunters have supported more than 1,200 clients through this final step. This guide details the signing process, the documents to prepare and the key points to be aware of.

What is the authentic deed of sale

The authentic deed is a legal document drafted and signed by a public officer, the notaire. Unlike the preliminary contract, which is a pre-contract committing the parties, the authentic deed effects the actual transfer of ownership.

This document carries enhanced evidentiary value: it is presumed accurate until challenged through a specific judicial procedure known as inscription de faux. Concretely, the information it contains (identity of the parties, description of the property, price, conditions) is presumed exact and enforceable against third parties.

The authentic deed is mandatory for any property sale in France. It cannot be replaced by a private agreement. The notaire who drafts it bears professional liability for the accuracy of the legal checks they have carried out.

In Paris, the buyer and seller may each choose their own notaire. The two notaires then share the fees at no additional cost to the parties. This practice is common and allows each party to benefit from independent counsel.

The timeline between preliminary contract and authentic deed

The standard timeline between signing the preliminary contract and the authentic deed is 2 to 3 months in Paris. This timeline, which may seem long, corresponds to essential steps that cannot be shortened.

Clearing the urban pre-emption right (DPU) takes 2 months. The City of Paris has this period to decide whether it wishes to acquire the property first. In practice, effective pre-emptions represent less than 1% of transactions, but the timeline must be observed.

Obtaining financing typically requires 4 to 6 weeks after the preliminary contract is signed. The conditions precedent in the preliminary contract set a specific deadline, usually 45 to 60 days, for obtaining the loan offer.

Notarial checks include the mortgage status of the property, the co-ownership situation (article 20 certificate under the 1965 law), technical diagnostics and any easements. The notaire also verifies the absence of ongoing legal proceedings affecting the property.

In 2026, the growing digitization of notarized deeds in Paris is accelerating certain steps. Electronic signing of the authentic deed is now common and allows geographically distant buyers, particularly expats, to sign remotely using a notarized power of attorney.

Documents to prepare before the signing

The buyer must provide several documents to the notaire in the weeks preceding the signing. A valid form of identification (national ID card or passport) is essential. A proof of address less than 3 months old is also required. The family record book or marriage certificate is needed if the buyer is married or in a civil partnership.

The final loan offer, signed and for which the 10-day reflection period has been observed, must be submitted. The mortgage insurance certificate completes the financing documentation. If the buyer has used a bridging loan, the corresponding documents are also needed.

The notaire also requests the buyer’s full bank details for the wire transfer of funds. The total amount, purchase price, notaire fees, and any property hunter fees, must be available in the notaire’s escrow account on the day of signing.

On the seller’s side, the notaire will have collected the title deed, the full technical diagnostics package (EPC, asbestos, lead, termites, Carrez law, etc.), the co-ownership regulations and the minutes from the last three general meetings.

The signing process at the notaire’s office

The signing of the authentic deed follows a codified procedure. The appointment typically lasts between 1.5 and 2.5 hours.

The notaire begins by reading the entire deed aloud. This reading, required by law, may seem tedious but is essential. It allows the parties to verify every element: identity, property description, net seller price, sale conditions, any easements.

The notaire then details the appendices: technical diagnostics, mortgage status, co-ownership certificate, Carrez law surface attestation. Each appendix is initialed by both parties.

Then comes the actual signing. The buyer and seller sign each page and the final page of the deed. If the signing is electronic, it is done on a tablet with a digital identity certificate.

The notaire then proceeds to release the funds. The sale price, previously wired to the notaire’s escrow account, is transferred to the seller. The deposit made at the time of the preliminary contract is deducted from the price.

The day itself: payment and key handover

Payment for the property takes place on the day of signing. The buyer must have wired the full amount (personal contribution + mortgage disbursement) to the notaire’s account at least 48 hours before the appointment. Any delay in the wire transfer may result in a postponement of the signing.

Notaire fees, approximately 7% to 8% of the net seller price for older properties, are also paid to the notaire on the day of signing. In 2026, for an apartment purchased for 700,000 euros in Paris, notaire fees amount to approximately 50,000 to 56,000 euros.

Key handover takes place in principle on the day of signing, unless a deferred possession is stipulated in the preliminary contract. The buyer receives all keys (front door, cellar, mailbox, bin storage, gate) as well as access badges and parking remote controls where applicable.

The notaire provides the buyer with a provisional ownership certificate on the same day. The definitive title deed is sent within 3 to 6 months, after registration with the land registry.

Meter readings (water, electricity, gas) are taken on the day of signing or on the day of key handover to enable the transfer of energy contracts.

The apartment hunter’s role during the signing

At Home Select, our support does not end with the price negotiation. Our apartment hunters follow the file through to the signing of the authentic deed and, in most cases, attend the signing in person.

This presence serves a concrete purpose. The property hunter verifies that the authentic deed conforms to the preliminary contract and to the negotiated conditions. They ensure that the appendices (diagnostics, Carrez surface area, co-ownership status) match the information communicated during the sale. They flag any anomaly to the notaire.

For foreign or expatriate buyers, the property hunter can coordinate the signing with the various parties involved: both notaires, bank, insurer, and facilitate the process when signing is done by power of attorney.

This end-to-end support, from the first viewing to the key handover, is at the heart of our commitment. Our case studies illustrate this approach on recent transactions.

FAQ

What is the timeline between the preliminary contract and the authentic deed?

The usual timeline between signing the preliminary contract and the authentic deed is 2 to 3 months in Paris. This period allows the notaire to gather administrative documents, the buyer to obtain financing and to clear the urban pre-emption right. Delays can extend this timeline to 4 months.

Can the signing of the authentic deed be postponed?

Yes, a postponement is possible if both parties agree. Common causes include a delay in obtaining the mortgage, a missing administrative document or a pre-emption right not yet cleared. The postponement is formalized by an amendment to the preliminary contract. An unjustified unilateral postponement may trigger contractual penalties.

What happens if the buyer does not show up for the signing?

If the buyer fails to appear without legitimate reason, the seller can serve formal notice through a bailiff, then request the cancellation of the sale and retain the security deposit (generally 5% to 10% of the price). In some cases, the seller may also claim additional damages before the court.
