Notary and Mortgage Renewal: Beware the Extent of Their Duty

Imagine: you sell your house in Bricquebec, in the Manche department. The notary drafts the deed, collects the price, but you have not been paid in full. Your vendor's lien (the security that allows you to be paid in priority if the buyer does not pay) is registered for five years. If no one thinks to renew it before the deadline, your security vanishes. Whose fault is it? The notary's, who should have warned you? This is precisely the question the Court of Cassation decided on 25 May 1982.

This decision, little known to the public, answers a question any property owner might ask: "Is the notary required to take all useful steps to protect my interests, even without specific instructions?" The judges' answer is clear: no, unless given a special mandate. In other words, if you did not expressly entrust the notary with renewing the registration, they do not have to do it on their own initiative.

In this article, we will dissect this case, understand the reasoning of the judges, and see concretely what it means for you, whether you are a seller, buyer, or property professional. And I will give you four tips to ensure you never find yourself in the situation of that unfortunate seller.

The Facts: A Story That Happens Every Day

In 1974, the company Sovac granted a loan to Mr X, secured by a registration of a vendor's lien on a property located in Lessay. The registration was valid for five years, until 1979. In 1976, Mr X resold the property to a third party. The notary drafted the sale deed and the price was paid partly in cash, partly in instalments. Sovac was not fully paid off: it was still owed 76,850 francs.

However, at the expiry of the registration, no one renewed it. The lien was extinguished. When the order proceedings (distribution of the price among creditors) were opened, Sovac found itself without security and could only be paid from the surplus, which was far less than its claim. Furious, it sued the notary for negligence, arguing that the notary should have renewed the registration on its own initiative – or at least warned it of the need to do so.

The Court of Appeal ruled in favour of Sovac: in its view, the notary, as drafter of the deed, had a duty to advise and should have carried out the necessary formalities to preserve the seller's rights. But the Court of Cassation quashed this judgment. It held that the notary was not obliged to renew the registration, because Sovac had given no mandate to that effect. Moreover, the loan deed specified that the release (cancellation of the registration) was only given to the extent of payment, which did not imply an obligation of automatic renewal.

The Reasoning of the Court — Dissected

The Court of Cassation relied on Article 1382 of the Civil Code (now 1240), which sets out the principle of liability for fault. For a notary to be held liable, there must be a fault, a breach of their duty to advise. But what is the content of this duty? The Court recalled that the notary is not a universal insurer. Their duty to advise extends to what is necessary for the effectiveness of the deed they draft, but no further, unless there is an express mandate.

In this case, the sale deed contained no clause entrusting the notary with the task of renewing the registration. Sovac, although a creditor, had also given no instructions to that effect. Therefore, the notary did not have to intervene. The Court of Appeal had considered that the notary should have drawn the parties' attention to the approaching deadline. But the Court of Cassation held that this duty of information did not go so far as to require a positive act of renewal. In other words, the notary must explain, but not act on the client's behalf without authorisation.

This decision confirms previous case law: the notary is not the general guardian of their clients' interests. They have a duty to advise, but this duty has limits. The judges distinguish here between advice (informing, warning) and execution (carrying out formalities). Without a mandate, execution does not fall on them. One may see some strictness, but also logic: the notary cannot guess what their client wants. Perhaps the seller wanted to let their security lapse? Perhaps they had another arrangement?

What This Means for You — Concretely

If you are a seller: you have sold a property and part of the price remains unpaid. You benefit from a vendor's lien, registered at the land registry for five years. If you want it maintained beyond those five years, it is up to you to request renewal. The notary will not do it automatically. And if you forget, you lose your priority ranking. For example, in Lessay, a seller who had an unpaid balance of €50,000 found themselves trumped by another creditor because their registration had not been renewed. They lost everything.

If you are a buyer: this decision also protects you, because it prevents the notary from renewing registrations without your consent, which could block the sale. But be vigilant: always check, before buying, that prior registrations have expired or been cancelled.

If you are a property professional (agent, developer): know that the notary is not your permanent legal assistant. If you want them to follow a case over time (renewal of securities, cancellations, etc.), you must give them a written mandate. A simple email may suffice, but a clause in the deed is better.

Four Tips to Avoid This Type of Dispute

• Give a written mandate to the notary: if you sell on credit, expressly ask the notary to renew the mortgage registration at its expiry. Specify the terms in a separate deed or a clause in the sale deed.
• Note the expiry date in your diary: the registration lasts five years. Mark the date in your calendar and, six months before, contact your notary to check if a renewal is necessary.
• Require a statement of registrations before the sale: ask the notary for a schedule of mortgages. This will allow you to know which securities are about to expire and take the necessary measures.
• Include a reiteration clause: in the sale deed, insert a clause obliging the notary to inform you of any important deadlines in the months following the sale.

Further Reading: Related Case Law and Developments

This 1982 decision is part of a consistent line. A few years earlier, the Court of Cassation held that the notary is not required to check the existence of a non-apparent easement (Civ. 1re, 1975). More recently, in 2015, it recalled that the notary's duty to advise does not include detecting a miscalculation of the price by the buyer (Civ. 1re, 2015, No. 14-17.123).

The trend is therefore clear: the notary must advise, but not compensate for the client's negligence. Since 1982, case law has even reinforced this idea by requiring an express mandate for any material act (renewal, cancellation, etc.). For the future, one can expect courts to continue in this direction, unless the legislature intervenes to impose a broader obligation. In the meantime, the best advice remains: do not rely on the notary to do for you what you can do yourself.

Checklist Before Acting

• Have I given a written mandate to the notary to renew the registration? If not, do so today.
• What is the expiry date of my mortgage registration? Check on the loan deed or ask for a statement from the land registry.
• Have I included a clause in the sale deed for the notary to alert me of deadlines? If not, add it by addendum before signing.
• In case of doubt, should I consult a lawyer? Yes, especially if the amount at stake is large (over €10,000). A lawyer specialising in property law can advise on precautions to take.
