An elderly parent took out a prêt viager hypothécaire, the French lifetime mortgage, to top up their income. On their death, you discover that the debt has caught up with the value of the house and that the original valuation looks high. What can be challenged, and within what time? The decision of the First Civil Chamber of the Cour de cassation (French supreme court for civil and commercial matters) of 19 June 2024 (appeals no. 22-20.533 and 22-21.719) gives precise answers on the place of the property valuation in this contract.
The French lifetime mortgage in brief
The prêt viager hypothécaire is defined by the French Consumer Code (article L. 315-1). A credit institution lends an individual a lump sum or periodic payments, secured by a mortgage on a residential property. Repayment is due only on the borrower’s death, or when the property is sold or its ownership split. Interest is rolled up for the whole term of the contract.
The amount lent depends directly on the value of the property. The Consumer Code provides that this value is estimated by an expert, and the debt due at the end cannot exceed the value of the property at that time. The initial valuation therefore governs both the capital paid out and the balance of the contract for the heirs.
The facts
Two lifetime mortgages had been granted by the same lender in 2007 and 2010. After the borrower’s death, the heirs sought to have the loans annulled for defective consent, arguing that the mortgaged property had been overvalued in the prior valuation. The PARIS Court of Appeal had dismissed their claim by a ruling of 22 June 2022. The Cour de cassation partially quashes that ruling.
The four lessons of the decision
The claim for annulment need not be registered
A claim for annulment of a lifetime mortgage is not subject to the land registration required by articles 28 and 30-5 of the decree of 4 January 1955. The heirs therefore did not have to register their writ with the land registry for their claim to be admissible.
Time runs from the discovery of the mistake
A claim for annulment on the ground of mistake is time-barred after five years. In the case of mistake, that period runs only from the day it was discovered (former article 1304 of the French Civil Code for contracts predating 2016, article 1144 today). The Court of Appeal should have asked on what date the borrower, then the heirs, could have known the full extent of the defect. An overvaluation may come to light only on death, when the debt and the real value of the property are set against each other.
The valuation of the property is decisive for consent
This is the main lesson. For the Cour de cassation, in a lifetime mortgage, the expert valuation of the mortgaged property is necessarily decisive for the borrower’s consent. The Court of Appeal could therefore not reject annulment on the ground that the overvaluation would not have been a decisive mistake. A mistake as to an essential quality of the performance is a ground for annulment (article 1132 of the Civil Code, former article 1110), provided it is excusable.
The lender has two years from identifying the heirs
The lender’s recovery claim is subject to the two-year limitation period applicable to professionals against consumers (French Consumer Code, article L. 218-2). The Court specifies that this period runs from the day the lender learns the identity of the borrower’s heirs. The Court of Appeal had to examine this question.
What the decision means for valuation
A valuation that binds. The prior valuation is not a formality. It sets the capital lent and, according to this decision, it enters into the borrower’s consent. A significant overvaluation can lead to the annulment of the loan, with the restitutions that follow.
A duty of care, but a documented one. The Charte de l’expertise en évaluation immobilière (the French property valuation charter, 6th edition, Title I, §2.2) recalls that the expert’s liability is a duty of care (obligation de moyens), not a guarantee of result. That presupposes a visit to the property, references to comparable sales cited and dated, and a report that sets out the method. This is what makes it possible, years later, to check that the value adopted was consistent with the market of the time.
A basis of value suited to lending. Market value, as defined by the Charte (Title III, §1.1) and by EVS 1 of TEGOVA’s European Valuation Standards, is the estimated amount for which the property would exchange on the valuation date between willing and informed parties. For a loan that will be repaid in ten or twenty years’ time, the lender is also interested in the mortgage lending value and the prudent value, conservative bases founded on the durable characteristics of the property and excluding any anticipation of price rises (Charte, Title III, §1.15 and §1.16; EVS 2 and EVGN 2). A report that clearly separates these bases protects borrower and lender alike.
A long window for challenge. A valuation error is often discovered when the estate is opened. The expert therefore keeps the file, the references and the assumptions well beyond the delivery of the report.
For the heirs
If you have doubts about the original valuation, the useful approach is to reconstruct the value of the property at the date of the loan: the condition of the property at the time, comparable sales of the period, the initial report if it is available. A retrospective valuation built on these elements measures the gap and shows whether it reflects a mere difference of opinion or a clear overvaluation.
