Introduction
The intervention of a notary is an essential step in any real estate purchase in France. As a public officer appointed by the Keeper of the Seals, the notary secures the transaction, guarantees its legal validity, and protects the interests of both parties. His role goes beyond simply drafting documents: he accompanies the buyer and seller from initial discussions through to the handover of keys. Understanding his duties allows the buyer to anticipate procedures, manage timelines, and optimize the overall cost of the acquisition. This article details the notary's legal obligations, his concrete duties, and best practices for collaborating effectively with him.
The Notary as Guarantor of Transaction Legal Security
The notary acts as a public officer delegated authority by the State. In accordance with Ordinance No. 45-2590 of November 2, 1945, he authenticates the documents he drafts, which gives them enforceability and a certain date. In a real estate purchase, this authentication is mandatory for any property transfer, under Article 4 of the Decree of January 4, 1955 relating to property publicity.
Before signing, the notary performs thorough verifications: the seller's title of ownership, absence of hidden mortgages or easements, urban compliance of the property (certificate of urbanism, urban right of first refusal), compliance with mandatory technical reports (Energy Performance Certificate, asbestos, lead, termites, Electrical Installation Safety Report). He also ensures that both parties have the legal capacity to contract.
The Notary's Concrete Duties During the Purchase
The notary's interventions take place in several stages. He first drafts the offer or promise to sell, a document that sets the final conditions of the transaction. During the 10-day withdrawal period provided for in Article L.271-1 of the Construction and Housing Code, the buyer may withdraw without penalty.
Between the offer and the authentic deed (usually 2 to 3 months), the notary collects mandatory documents: mortgage status, civil status certificate, property tax situation, co-ownership documents if applicable (Article L.721-2 of the CCH). He also calculates the transfer tax (approximately 5.80% of the price for existing property) and prepares the final deed.
On signing day, he reads the authentic deed aloud, collects funds, hands over keys, and publishes the sale with the property register office within one month following signature.
Notary Fees and Charges
Contrary to popular belief, "notary fees" do not entirely go to the notary's office. They break down into three parts: rights and taxes (approximately 80%), returned to the State and local authorities; the notary's fees (approximately 10%), regulated according to Decree No. 2016-230 of February 26, 2016; and outlays (expenses advanced to obtain documents and certificates).
Since the Macron Law of August 6, 2015, notaries may grant discounts of up to 20% on their fees for transactions exceeding 100,000 euros, which is worth negotiating.
Practical Examples
Example 1 – Purchase of an apartment in a condominium in Lyon: For an older property at 350,000 €, the buyer signed an offer with his notary. The notary detected an easement of passage not initially mentioned and had the price renegotiated down by 8,000 €, preventing future litigation.
Example 2 – Acquisition of new construction (off-plan sale): During a sale in a state of future completion, the notary verified the developer's financial guarantee of completion (Article L.261-11 of the CCH) and secured phased payment calls according to construction progress.
Example 3 – Purchase with bridge loan: The notary coordinated the discharge of the old mortgage and the establishment of the new guarantee, allowing synchronized signature of both transactions.
Conclusion
The notary is far more than a mere document drafter: he is a neutral legal advisor who secures your entire real estate project. Choosing your own notary (free of charge, since fees are shared between the two offices in case of dual representation) allows you to benefit from personalized advice. Do not hesitate to consult him before the offer to anticipate tax, asset, or succession issues related to your purchase.
