Viager: Selling and Buying French Property on a Life Annuity

The Parties and the Basic Structure

The vente en viager is a property sale where the price is paid wholly or partly as a periodic life annuity (rente viagère) rather than as a lump sum. The contract is governed by C. civ. Art. 1968 et seq. The two parties have specific names that recur throughout the legal and tax framework:

The viager is sometimes described as an aliénation à fonds perdus — an alienation without recovery — because when the seller dies, their heirs recover neither the property nor any residual consideration: the rente simply ceases.

Viager Libre and Viager Occupé

Viager libre

In a viager libre, the seller transfers full ownership immediately and completely. The buyer can use the property straight away — by occupying it personally, by letting it, or by any other means. There is no démembrement of ownership rights: the seller simply no longer has any right to the property once the sale is concluded.

Viager occupé

In practice, the viager occupé is by far the more common form. The sale involves a démembrement of the property: the seller transfers bare ownership (nue-propriété) but retains either the usufruct (usufruit) or a droit d'usage et d'habitation (DUH).

The choice between usufruit and DUH matters significantly. Where the seller retains the usufruit, they may occupy the property personally or let it to a third party and collect the rents (C. civ. Art. 595). The possibility of a sitting tenant at the time of the seller's death is a disadvantage for the buyer, who cannot be sure of immediate vacant possession. This explains why the droit d'usage et d'habitation is more common in practice: the DUH gives the seller the right to occupy the property personally but prohibits them from letting it to a third party (C. civ. Art. 631). The buyer therefore knows that the property will be vacant on the seller's death.

The Contract: Key Elements

Form and content

A viager sale is first and foremost a property sale. It must satisfy all conditions for a valid property sale under C. civ. Art. 1582 et seq. — including notarisation and registration in the land register (fichier immobilier). It is almost always preceded by a preliminary contract (avant-contrat — promesse de vente or compromis) setting out all the terms. The preliminary contract must include: the price, distinguishing the bouquet (if any) from the rente; any démembrement arrangements; a reversibility clause for the surviving spouse if the rente is constituted on two lives; the allocation of maintenance and major repair obligations; and provisions for expropriation or destruction of the property.

The bouquet and the rente

In most viager transactions, a portion of the price is paid upfront in cash — the bouquet — and the remainder is converted into a periodic annuity payable for life. The bouquet is optional. The larger the bouquet, the lower the rente, and vice versa. The rente is freely set by the parties (C. civ. Art. 1976), but it must correspond to the real value of the property. If it does not, the contract may be annulled for lack of price. The courts have confirmed that a rente equal to or below the rental income the property would have generated is so low as to destroy the aleatory character of the contract and justify annulment.

The following elements are taken into account when calculating the rente:

• The market value of the property and its expected rental yield
• The existence and amount of the bouquet
• The life expectancy of the person on whose life the rente is constituted (based on mortality tables)
• Any reversibility clause (full or partial) in favour of a surviving spouse
• Whether the viager is libre or occupé (and whether the seller retains usufruit or DUH), since the value of the retained right reduces the basis for the rente

The Aleatory Requirement: When the Contract Is Void

The life annuity contract is fundamentally an aleatory contract: it is valid only if it involves genuine uncertainty (aléa) about the total price the buyer will pay. Without uncertainty, there is no cause and the contract is null. The Civil Code creates three specific nullity rules:

• Seller already dead at signing: A contract where the rente is constituted on the life of a person who had already died at the date of the contract is absolutely null (C. civ. Art. 1974).
• Death within 20 days of a pre-existing illness: A contract is also null where the person on whose life the rente is constituted dies within 20 days of the contract date from an illness they had at the time of the sale (C. civ. Art. 1975). This nullity is absolute.
• Buyer knew death was imminent: Even where death occurs more than 20 days after the sale, the courts may annul the contract if it is proved that the buyer knew the seller's death was imminent — regardless of the 20-day limit.

However, where the rente is constituted on two lives and only one of them dies within the 20-day period while the rente remains fully reversible and payable until the death of the last survivor, the contract is not void.

Paying the Rente: Mechanics and Obligations

Periodicity and payment terms

The parties freely determine the periodicity of payments — monthly, quarterly, or otherwise. Payment may be in arrears or in advance. The rente extinguishes automatically on the death of the person on whose life it is constituted. Where constituted on two lives (as is common for couples), it extinguishes on the death of the last survivor. By default, the rente is halved on the death of the first; a reversibility clause can modify this proportion, including providing for full continuity of the rente until the last survivor's death (C. civ. Art. 1973).

The buyer's obligations are perpetual — to their heirs

The débirentier must continue paying the rente until the crédirentier's death, regardless of the total accumulated cost (C. civ. Art. 1979). The buyer may not unilaterally redeem the rente — redemption requires the seller's agreement. Crucially, the death of the débirentier does not end the contract: their heirs must continue paying the rente. Similarly, if the débirentier sells the property to a third party, the original débirentier remains guarantor of the rente payments unless the crédirentier expressly releases them.

The seller's right to waive

The crédirentier may validly renounce receipt of the rente and release the débirentier from future payments. However, this renunciation is never presumed — it must be express. Where the sale deed provides that the seller may renounce a DUH by registered letter with six months' notice, a tacit renunciation is insufficient.

Payment Guarantees

The seller has two main protections against non-payment of the rente.

First, the privilège du vendeur: the seller's vendor's privilege is registered at the land registry (service chargé de la publicité foncière). This gives the crédirentier a security right over the property, enabling them to have it seized and sold if arrérages are not paid.

Second, and typically stipulated expressly in the sale deed: two automatic termination clauses (clauses résolutoires de plein droit) enabling the seller to have the sale annulled in the event of non-payment — one for the bouquet, one for the rente. In the event of annulment, the parties are restored to their pre-sale positions, but the courts generally accept that a portion of the arrérages already paid will remain with the seller as damages. The sale deed may also include a clause pénale stipulating this in advance — though the court may revise it upward or downward if it is excessive or derisory.

Indexation of the Rente

Viager rentes are almost always indexed. This contractual indexation benefits from a specific exemption: rentes viagères are assimilated to alimentary debts for the purposes of C. mon. fin. Art. L 112-2, which means the choice of index is free — a viager rente may, for example, be indexed to the general consumer price index.

Indexation is subject to a ceiling: it must not have the effect of raising the arrérages above an amount whose capitalised value exceeds the value of the property transferred (Loi 49-420 du 25 mars 1949, Art. 4, al. 1). A statutory floor also applies: regardless of what contractual indexation has been agreed, the arrérages must at minimum receive the mandatory annual uplifts fixed each year by ministerial order (Loi 51-695 du 24 mai 1951, Art. 2). The débirentier may obtain relief from the mandatory uplift if their personal financial situation does not allow them to bear its financial consequences.

Where the economic equilibrium of the contract is disrupted by new economic circumstances, the rente may in certain cases be subject to judicial correction. In principle, judicial revision actions may only be brought once per contract. In practice however, each new ministerial order setting the mandatory uplift rates reopens the period for bringing revision actions — so multiple revision actions are possible over the life of a long-running viager contract.

Tax Treatment — the Crédirentier (Seller)

Transfer duties

Like all property sales, a viager sale triggers payment of registration duties (droits d'enregistrement) under the ordinary rules. The duty base is the capital value of the rente as expressed in the deed, plus any bouquet.

Capital gains tax

The seller's capital gain is calculated in the ordinary way for private real estate disposals, with one specific rule for the price of cession: where a property is sold en viager, the disposal price to be used in the capital gains calculation is the capital value of the rente — excluding the interest component — plus any bouquet (CGI Art. 150 VA, I). Even though payments will be received over many years, the capital gain is computed and taxed entirely in the year of the sale, not spread over the years of payment.

Income tax on the rente received — the Art. 669 taxable fractions

The rente viagère received by the crédirentier is taxable income — but only on a fixed fraction of each payment, determined once and for all at the time the rente begins, based on the seller's age at that date (CGI Art. 669). The fraction is:

This fraction is fixed permanently at the age at the time the rente first becomes payable — it does not change as the crédirentier ages. A seller who begins receiving their rente at age 72 will always have 30% of each arrérage taxed, even decades later. The income tax on the rente is collected by withholding at source in the form of advance payments (acomptes).

Tax Treatment — the Débirentier (Buyer)

Income tax

The débirentier has no special income tax deduction for the rente paid. Because the rente constitutes the purchase price of an asset — not a gift or an alimentary obligation — it generates no deductible charge against the buyer's income. The débirentier must however declare to the tax authorities, before 1 February each year, the total arrérages paid during the preceding year together with the identity of the beneficiary — mandatorily by electronic declaration. Failure to declare, or late declaration, attracts a penalty of 5% of the amounts not declared or declared late (CGI Art. 1736, III).

Capital gains on resale of a viager-acquired property

If the débirentier later sells the property, the capital gain is calculated as the difference between the resale price and the acquisition cost. Determining the acquisition cost requires care:

• Standard rule: the acquisition price is the capital value of the rente at the time of original purchase, plus any bouquet.
• Alternative method (BOI-RFPI-PVI-20-10-20-10 n° 80): the buyer may choose to use as acquisition cost the total of (i) arrérages actually paid up to the resale date, plus (ii) the capital value of the rente remaining to be paid at the resale date, plus (iii) any bouquet — if the crédirentier is still alive at resale; or simply total arrérages paid to date plus any bouquet — if the crédirentier has since died.

IFI (Wealth Tax) Treatment

The débirentier's IFI position

The débirentier must include the value of the acquired property in their IFI base. In a viager occupé, the débirentier holds only bare ownership, so it is in principle only the value of the nue-propriété that must be declared — subject to any applicable IFI exemption. The débirentier may deduct from their IFI base the capital representative value of the rente still owed to the crédirentier.

The crédirentier's IFI position

The capital representative value of the rente is not included in the crédirentier's IFI base: it is not a real property right or interest falling within the scope of the tax. However, if the crédirentier has retained an usufruit or a droit d'usage et d'habitation over the property (viager occupé), they must include the value of that right in their IFI base, evaluated using the actuarial tables of CGI Art. 669 — unless the débirentier is considered a presumptive heir of the crédirentier within the meaning of CGI Art. 751. If they are, the crédirentier must declare the full market value of the property in full ownership rather than just the value of their usufruit or DUH (CGI Art. 968, 2°).

Taxe Foncière

In a viager occupé where the seller has retained only a droit d'usage et d'habitation (not a full usufruit), it is the buyer (débirentier) who is the legal taxpayer for taxe foncière on built properties — not the seller who continues to occupy the property.

This article covers the French vente en viager framework based on applicable French legislation as cited. The mandatory uplift table (Arrêté ECOB2234192 du 23 décembre 2022) gives the rates applicable from 1 January 2023 — a new ministerial order is published each year and the applicable table should always be verified. The CGI Art. 669 taxable fractions apply specifically to rentes viagères constituted "à titre onéreux" (as consideration for an asset transfer). The IFI provisions cite CGI Art. 968, 2° and CGI Art. 751 on the presumptive heirs rule. Taxe foncière liability in the DUH case references BOI-IF-TFB-10-20-20 n° 100.
