A viager (life-annuity sale) lets a buyer acquire French property at a discount in exchange for paying the seller an annuity for life. For a foreign buyer, the mechanism looks like a bargain: a Paris flat worth 600,000 euros might change hands for an upfront payment of 180,000 euros plus a monthly annuity. But the discount has a legal explanation, and the risks are real: if the price structure leaves the buyer with no genuine risk, courts annul the sale; if the seller dies within twenty days, the sale collapses; and if the buyer stops paying the annuity, the seller’s remedies depend entirely on clauses the parties thought to insert. This guide explains how the price is built, who pays for what, and where foreign buyers most often go wrong.
I. How a Viager Sale Works and What the Foreign Buyer Actually Pays For
A. Occupied and free viager: who lives in the property and who pays what
A viager is a sale of real estate in exchange for a rente viagère (life annuity): the buyer, called the débirentier (annuity debtor), pays the seller, called the crédirentier (annuitant), a periodic sum until the seller’s death, sometimes plus a lump sum paid at signing called the bouquet. When the seller dies, the annuity ends and the buyer holds the property free of any further formality. As with every sale of French real estate, the deed must be an acte authentique (notarial deed) drawn up by a notaire (French public officer conveyancer). A private agreement alone cannot transfer the property.
The first choice the parties make is between a viager occupé (occupied life-annuity sale) and a viager libre (unoccupied life-annuity sale), and this choice determines everything about enjoyment, rental income and running costs. In an occupied viager, the seller keeps either the usufruit (usufruct, the right to use the property and collect any rental income from it) or a droit d’usage et d’habitation (personal right of use and occupation) until death. The distinction matters in practice: an usufructuary may live in the flat or let it and keep the rent, while the holder of a mere right of use may live there personally but may not let it. In a free viager, the buyer takes possession immediately, may move in or let the property and keeps any rent from day one.
Who pays for maintenance, repairs and taxes follows the occupancy pattern, and the default rules come from the Civil Code provisions on usufruct. The usufructuary bears only routine maintenance, while major structural work stays with the bare owner, since Article 605 of the Civil Code provides that the usufructuary is liable only for réparations d’entretien (routine maintenance) and that grosses réparations (major structural repairs) remain the owner’s burden. The same Code defines those major repairs in Article 606 of the Civil Code as work to main walls and vaults, the restoration of beams and entire roofs, and entire dykes, retaining walls and fences. Annual charges follow the fruits: Article 608 of the Civil Code makes the usufructuary liable during enjoyment for all annual charges of the property, such as contributions and others treated as charges on the fruits. In practice, the French administration’s guidance confirms this split for occupied viagers: absent a clause to the contrary, the seller pays routine repairs, energy bills, the taxe foncière (French property tax) and household waste collection tax, while the buyer funds the major structural repairs; in a free viager, the buyer pays everything. Foreign buyers should nevertheless read the deed carefully, because the Code default on annual charges is not a matter of public policy: the Cour de cassation has held that buyers of the nue-propriété (bare ownership) of a building in exchange for a life annuity, having become legal possessors from the day of the sale through the usufructuary, must reimburse her the property taxes where the contract so stipulates, the parties being free to depart from Article 608 (Cass. 1re civ., 3 June 1997, no. 95-16.484). Whatever the deed says about charges binds the buyer, so the negotiation of these clauses is as important as the price itself.
One fine distinction deserves attention from any buyer of an occupied viager: a reserved droit d’habitation (right of occupation) is strictly personal to the seller, yet it still allows family life. The Cour de cassation approved a court of appeal which held that a sale deed granting a right of occupation personally to the seller alone did not derogate from Article 632 of the Civil Code, under which the holder of such a right may live in the house with her family, so the seller committed no fault by accommodating her son, daughter and grandson (Cass. 3e civ., 7 Dec. 2005, no. 04-15.218). A foreign buyer who expects a solitary elderly occupant should therefore understand that grandchildren may lawfully move in, and should verify exactly which right, usufruct or mere use and occupation, the deed reserves. For an overview of how French ownership structures affect foreign purchasers generally, the real estate practice in Paris regularly assists international buyers with these deed clauses before signature.
B. Bouquet and rente: how the price is calculated and indexed
The price in a viager normally has two components: the bouquet paid cash at signing, which is optional and freely agreed, in practice often around 30 percent of the total value, and the life annuity itself, which may be paid to one or more sellers, monthly, quarterly or annually. Where several sellers share the annuity, the deed provides either for a rente réversible (reversible annuity, paid in full to the survivor) or a rente réductible (reducible annuity, reduced on the first death). The total cost to the buyer is inherently uncertain because it depends on the seller’s lifespan, which is precisely the point of the transaction: the price is estimated from the seller’s age and life expectancy, the market value of the property, the amount of any bouquet, and the rental value the property would yield if let. The notaire computes the annuity using actuarial scales available from insurers and notarial bodies.
French law gives the parties wide freedom to set the annuity: Article 1976 of the Civil Code states that a life annuity may be constituted at whatever rate the contracting parties choose to fix. Freedom does not mean arbitrariness, however, because the annuity must reflect a genuine life risk, a point developed in Part II below. Parties commonly add an clause d’indexation (indexation clause) tying the annuity to a published index such as the consumer price index of the INSEE, the French national statistics institute, so that inflation does not erode the seller’s income over a long life. Indexation has real legal teeth: the Cour de cassation has ruled that indexation is a component of the life annuity itself, so that the right to indexation can only be extinguished by the thirty-year limitation period together with the right to the annuity service itself (Cass. 1re civ., 5 Dec. 2006, no. 03-15.414). A buyer who neglects indexation arrears for years cannot therefore treat them as time-barred independently of the annuity; the limitation period for the indexation runs with the underlying right to the annuity, and the thirty-year period cited by the Court applies to that extinction.
Tax follows the two components separately, and foreign buyers must budget for both sides of the equation. Only a fraction of each annuity payment is subject to income tax in the seller’s hands, with the taxable fraction falling as the seller’s age at the first payment rises: 70 percent where the first payment occurs before age 50, 50 percent between 50 and 59, 40 percent between 60 and 69, and 30 percent beyond 69, according to the French administration’s published guidance. The bouquet is not treated as income but falls under the capital gains regime on real estate, which may be fully exempted, notably where the property sold en viager is the seller’s principal residence. For a non-resident buyer, the acquisition itself triggers the usual French registration duties and notarial costs on the stated price, and a later resale falls under the non-resident capital gains framework, including the possible appointment of a représentant fiscal (accredited tax representative) depending on the seller’s residence at the time of resale. These fiscal signals are not tax advice: rates, allowances and treaty relief change, and any buyer should have the numbers verified for the year of the transaction before signing.
II. The Legal Risks and Remedies: Alea, Nullity, Non-Payment and Exit
A. The alea requirement: when courts annul a viager for lack of genuine risk
Every viager is a contrat aléatoire (aleatory contract), meaning a contract whose economic outcome for each side depends on an uncertain event, here the date of the seller’s death. The current definition, found in Article 1108 of the Civil Code, states that a contract is aleatory where the parties accept to make its effects, in terms of resulting advantages and losses, depend on an uncertain event: “Il est aléatoire lorsque les parties acceptent de faire dépendre les effets du contrat, quant aux avantages et aux pertes qui en résulteront, d’un événement incertain.” If that uncertainty is missing, because the seller is already dying or the price structure guarantees the buyer a profit whatever happens, there is no viager in the legal sense, and courts annul the sale.
The consequences of genuine alea protect the buyer as much as the seller. Where a court of appeal finds, in the exercise of its sovereign assessment, that a sale of a building in exchange for a life annuity is aleatory in character, it rightly concludes that the sale cannot be rescinded for lésion (gross undervalue): the aleatory character of a contract excludes any finding of imbalance between the parties’ reciprocal performances (Cass. 1re civ., 14 June 1977, no. 76-11.458). A foreign buyer who pays annuities for thirty years and ends up paying twice the market value therefore has no claim for undervalue, just as the seller’s heirs have no claim if the seller dies a month after signing. The risk cuts both ways, and that symmetry is the legal justification for the discounted entry price. Conversely, the price must be real and serious from the outset: seised of an action for nullity for lack of a serious price in a sale of buildings in exchange for a life annuity and benefits in kind, a court of appeal does no more than use its sovereign power of assessment in holding, by comparing the income of the property sold and the interest on the capital it represents with the lower value of the benefits provided, that the price lacked reality and that the buyers exposed themselves to no risk in exchange for acquiring ownership (Cass. 3e civ., 9 Feb. 1977, no. 75-14.987).
The courts apply this test concretely to the numbers in the deed. In a leading case, judges noted that the market value of the building, stated in the deed at 2,200,000 francs, was in reality close to 4,860,000 francs, and that the annuity, computed with regard to the age of both annuitants, the reservation of the right of enjoyment and the burden of major repairs, exceeded by more than double the annuity provided for; they lawfully annulled the sale for lack of a real and serious price, holding on sovereign grounds that the annuity was derisory and the sale devoid of alea, the buyer being certain of a gain well beyond the annuitants’ life expectancy (Cass. 3e civ., 12 June 1996, no. 94-16.988). Foreign buyers should draw a practical lesson: an annuity that looks attractively low can destroy the very sale it was meant to secure, because the seller’s heirs may later have it annulled and recover the property. The assessment also accounts for exactly what enjoyment the seller kept: where a viager sale reserved enjoyment to the seller until her definitive departure to a retirement home or her death, the Cour de cassation quashed a ruling that had compared the monthly annuity with the interest the capital would yield, noting that the capital to consider is not simply that of the bare ownership, since the reserved enjoyment disappeared when the seller left for the home, and that where the seller reserved enjoyment, alea and price seriousness are assessed by comparing the annuity with the interest the capital represented by the encumbered property would yield (Cass. 3e civ., 16 July 1998, no. 96-12.720). Every reservation clause, departure to care, reversionary annuity or retained charge changes the actuarial balance, which is why the computation should be documented by the notaire rather than agreed informally.
Good faith at the time of signing completes the picture. Where a sale of buildings is made for a price consisting partly of a cash payment and partly of a life annuity, and the trial judges find proof that the buyer did not know of the imminence of the seller’s death, they may sovereignly hold the sale aleatory in character, the price being fixed as Article 1591 of the Civil Code requires, determined and designated by the parties (Cass. 3e civ., 22 Mar. 1977, no. 76-10.045). A buyer who knew the seller was dying takes the opposite risk: the absence of genuine uncertainty exposes the sale to annulment at the heirs’ suit. Diligence before signing, including verification that the seller’s state of health is not known to be terminal, is therefore not morbid curiosity but a condition of the transaction’s legal survival. Foreign buyers negotiating at a distance should mandate verifications on site rather than relying on an intermediary’s assurances.
B. Death within twenty days, unpaid arrears and practical remedies
Two black-letter prohibitions frame every viager, and both concern death. Article 1974 of the Civil Code provides that any life-annuity contract created on the life of a person who was already dead on the day of the contract produces no effect. Article 1975 of the Civil Code extends the rule to the seller who was already ill: “Il en est de même du contrat par lequel la rente a été créée sur la tête d’une personne atteinte de la maladie dont elle est décédée dans les vingt jours de la date du contrat.” In other words, where the annuity was created on the life of a person suffering from the illness from which she died within twenty days of the contract date, the contract is treated the same way, without effect. The Cour de cassation gives this nullity the strongest possible status: the fact that the cash fraction of the price and the first annuity instalment were paid by the buyer in accordance with the deed does not deprive the heir of the annuitant who died within twenty days of the contract date of the right to invoke the nullity of public policy enacted by Article 1975 (Cass. 3e civ., 10 Nov. 1992, no. 90-21.417). Because the nullity is a matter of ordre public (public policy), the parties cannot waive it in advance, and even full performance by the buyer, bouquet and first arrears paid on time, cannot save the sale. The heir claims nullity before the court, and the twenty-day period runs from the date of the contract, as the decisions consulted in this article consistently state; no consulted decision extends, suspends or resets that period, and any argument to that effect would need its own source.
The mirror risk is non-payment of the annuity, and here the default law surprises many buyers: mere default does not undo the sale. Article 1978 of the Civil Code provides that the mere failure to pay the annuity arrears does not entitle the annuitant to demand repayment of the capital or to re-enter the property transferred: “Le seul défaut de paiement des arrérages de la rente n’autorise point celui en faveur de qui elle est constituée à demander le remboursement du capital, ou à rentrer dans le fonds par lui aliéné : il n’a que le droit de saisir et de faire vendre les biens de son débiteur et de faire ordonner ou consentir, sur le produit de la vente, l’emploi d’une somme suffisante pour le service des arrérages.” The seller’s default remedy is therefore seizure and sale of the buyer’s assets to fund the annuity, not recovery of the flat. In practice, deeds routinely correct this imbalance with a clause résolutoire (termination clause) allowing the seller to repossess the property if several instalments go unpaid, often combined with a clause pénale (penalty clause) letting the seller keep the bouquet already paid. The Cour de cassation accepts such derogations from Article 1978 but polices their operation strictly: while the action for resolution of the life-annuity contract, opened to the annuitant by a stipulation derogating from Article 1978, passes to her heirs, it does so only on condition that she accomplished in her lifetime the formalities provided by that clause (Cass. 1re civ., 15 June 1994, no. 92-14.907). A seller who never served the required formal notice before dying leaves her heirs without the resolution action, whatever the deed says. Foreign buyers should read the termination clause as the true security package of the transaction: its triggers, notice periods and forfeiture of the bouquet determine what a payment difficulty really costs.
Consumer protection adds a final layer that directly concerns foreign buyers approached outside an agency. The Cour de cassation has held that the sale of a building en viager concluded following doorstep canvassing is subject to the provisions of the Consumer Code on canvassing, so that a sale promise lacking the notice and the form allowing the seller to exercise the right of renunciation, as required by the applicable consumer provisions, is void (Cass. 1re civ., 3 July 2008, no. 06-21.877). Intermediaries who contact elderly owners at home and then present a foreign investor as the buyer operate inside this protective regime, and a missing withdrawal form annuls the preliminary agreement. The decision cited states the principle of nullity for a non-compliant promise; it does not fix any particular withdrawal period, and no period should be assumed from it. Buyers should also note the succession dimension without mistaking this article for estate advice: Article 918 of the Civil Code subjects property transferred either subject to a life annuity or with reservation of usufruct to one of the line successors to a presumption relevant to the disposable portion, a mechanism whose operation depends on family circumstances and on the 2006 reform of successions. Anyone buying en viager within a family arrangement needs dedicated succession analysis, which lies outside the scope of this conveyancing guide. The Paris real estate team examines these deed, termination and capacity points before funds are committed, while the transaction is still negotiable.
Conclusion
A viager rewards the buyer who understands that the discount is the price of uncertainty. Choose the occupancy regime deliberately, because usufruct, mere use and free possession allocate rents, taxes and major repairs differently and the deed can lawfully shift the statutory defaults. Have the notaire document the actuarial balance between bouquet, annuity, age and encumbered value, because a derisory annuity does not make a bargain but a nullity, while a genuine alea shields the sale even from claims of gross undervalue. Verify the seller’s situation in good faith, since death within twenty days from the contract date annuls the sale as a matter of public policy regardless of sums already paid. And negotiate the termination clause as carefully as the price, since without it the seller cannot recover the property for unpaid arrears, while with it the heirs can only act if the contractual formalities were completed in time. Built on these four checks, a viager remains what it has been since 1804: a demanding but coherent way to acquire French property, including from abroad.
