Joint ownership of French property: indivision, tontine & SCI

Welcome to the French joint property law system! Whether you are looking to acquire a luxury chalet in the ski resorts of the French Alps (such as Val Thorens, Alpe d’Huez, or the surrounding regions of Salins-Fontaine, Segny, and Grenoble), a premium apartment in Paris, or a villa on the Côte d’Azur, purchasing real estate is an important wealth management move.

However, when purchasing a property with a partner, family members, or business associates, choosing the right legal framework is a critical step.

Actes Alliances Notaire has offices in the heart of the French Alps including Salins-Fontaine, Segny, Val Thorens, Alpe d’Huez, and Grenoble.

For international investors, expatriates, and non-French buyers, local property and inheritance laws can look quite different from what they are used to at home. In France, the structure you select at the outset dictates how your property is managed, how decisions are made, and how the asset is passed on to your heirs.

Failing to plan for these aspects early on can lead to unexpected tax exposure, administrative reclassifications, or property disputes. Understanding the tax, legal, and inheritance implications of the three main joint ownership structures—Indivision, Tontine, and Société Civile Immobilière (SCI)—is therefore highly recommended.

2. What are the 3 Types of Joint Property Ownership?

Indivision (Undivided Ownership)

• Definition: This is the default ownership structure under French law. Co-ownership involves partners holding distinct, undivided shares in the property (e.g., 50/50 or 70/30) without any physical division of the premises.
• Typical use cases: It is commonly chosen by family members, unmarried couples, or friends who wish to purchase property together in a straightforward manner.
• Decision-making: Day-to-day management generally involves a two-thirds majority, but major decisions, such as selling the property, require the unanimity of all co-owners.
• Key risks: According to French law, no one can be forced to remain in an indivision structure. If one co-owner wishes to sell their shares and the others cannot afford to buy them out, the entire property may face a forced court sale.
• Inheritance implications: Upon a co-owner’s death, their share automatically enters their estate and is distributed to their legal heirs. This means an unmarried surviving partner could find themselves owning the property jointly with their late partner’s family or children.

Tontine (clause d’accroissement)

• Definition: A tontine is a specific contractual clause inserted directly into the purchase deed. Through a legal fiction, the last surviving co-owner is retroactively deemed to have been the sole owner of the entire property since the day of purchase.
• Typical use cases: Frequently utilized by unmarried couples or international buyers to ensure that the surviving partner automatically retains full ownership of the property upon death.
• Key risks: The tontine structure is quite rigid. All owners must agree on every major decision during their lifetimes. If a relationship breaks down, a co-owner cannot easily force a partition or a sale, unlike in an indivision layout.
• Tax and inheritance considerations: It bypasses standard French forced heirship rules for that specific asset, shielding the surviving partner from immediate claims by other heirs. However, the tax implications can be significant: for unmarried couples, the survivor may face a transfer tax rate of up to 60% on the deceased partner’s share.

SCI (Société Civile Immobilière)

• Definition: An SCI is a fully incorporated French civil property company established specifically to hold and manage real estate assets on behalf of its shareholders.
• Typical use cases: Highly recommended for long-term family holdings, investment properties, and complex cross-border wealth management.
• Structure: The property belongs to the company, and the investors hold corporate shares. It is governed by customized bylaws (“statuts”) and managed by a designated manager.
• Tax benefits: An SCI provides the flexibility to choose between the standard Income Tax (Impôt sur le Revenu – IR) or Corporate Tax (Impôt sur les Sociétés – IS), which can help optimize rental income and capital gains exposure depending on your investment profile.
• Inheritance flexibility: Shares can be progressively gifted or transferred to heirs over time, allowing parents to retain control and use of the property (via a life interest or “usufruit”) while reducing future inheritance tax burdens.

4. Practical Considerations for Buyers

When planning an acquisition across the French Alps, Paris, or the south of France, several practical variables should guide your choice:

• Contribution and Share Allocation: Especially within an Indivision, it is important to clearly define ownership percentages in the deed to match each buyer’s actual financial contribution. If allocations do not mirror the real funding layout, the French tax administration may view it as an undisclosed gift.
• Relationship Status: Married couples, civil partners (PACS), and unmarried co-owners do not receive the same legal protections under French law. The choice of structure should actively compensate for these legal differences.
• Long-Term Intentions: If you intend to run a holiday rental (such as a furnished ski chalet), note that a classic SCI taxed under the IR system cannot habitually carry out furnished lettings without being automatically reclassified under corporate tax (IS), which carries specific fiscal consequences.
• Financing & Mortgages: French banks routinely grant mortgages secured by property held in an Indivision or via an SCI. However, introducing a tontine clause can sometimes make banks more reluctant to lend, as the unpredictable nature of the clause complicates the registration of standard bank guarantees like mortgages. Note that when a loan is finalized at the moment of acquisition, the bank can benefit from a Legal Special Mortgage (HSPD), which is exempt from land registration tax and therefore more economical than a conventional mortgage.

5. Common Pitfalls in Joint Ownership and How to Avoid Them

• Failing to choose the correct structure early on: Attempting to alter your ownership setup after the final deed is signed can generate unnecessary transfer taxes and legal costs that could have been avoided with early planning.
• Overlooking administrative duties in an SCI: An SCI requires active corporate upkeep. If you fail to hold annual general meetings, maintain transparent accounts, or handle the necessary legal secretariat work, the tax authority may declare the company “fictitious”, canceling your tax planning benefits.
• Misunderstanding cross-border tax treaties: Non-residents often assume their home country’s tax rules apply. In reality, French property taxes, wealth tax (IFI), and inheritance rules interact closely with international tax treaties, creating risks of double taxation if not anticipated.
• Using informal agreements or standard internet templates: Relying on basic, uncustomized contracts downloaded online can leave co-owners exposed, as generic models often feature clauses that are legally void or poorly adapted to unique family situations.

6. The Role of the Notaire in Joint Ownership Structures

In the French legal system, a notaire is a public officer who ensures the compliance, validity, and security of real estate transactions. Only a notaire is authorized to authenticate a property sale in France. Hiring your own notaire does not increase your costs, as the regulated fees are simply shared between the two acting professionals.

When setting up your purchase, our specialized departments provide deep expertise backed by official legal guidelines:

• For Indivision: The notaire drafts the purchase deed, explains how undivided interests work, and can implement an official convention d’indivision to structure management and outline clear rules for financial contributions or eventual exit strategies.
• For Tontine: The notaire evaluates whether the necessary criteria for a tontine are met, inserts the clause safely into the deed, and advises on the long-term tax exposure for the surviving partner.
• For SCI: The notaire acts as a legal architect, drafts customized bylaws, defines the scope of the manager’s powers, protects founding partners with custom approval clauses (clauses d’agrément), and registers the entity with the proper corporate authorities.
• For Financing: The notaire coordinates directly with your bank to draft and register clear, legally sound security deeds (such as mortgages or HSPD), ensuring a smooth release of funds. Crucially, a notarized deed provides an enforceable title (titre exécutoire), allowing lenders or landlords to enforce their rights directly via a bailiff without requiring a lengthy court judgment.

7. Case Studies / Worked Examples

Example 1: A married couple purchasing via Indivision

An international couple married under a separate property regime purchases a premium apartment in Grenoble. One partner contributes 65% of the capital, and the other provides 35%. The notaire ensures these exact proportions are documented in the authentic deed. In the event of a future separation, the sale proceeds will be divided transparently according to these figures, protecting both parties’ initial financial injections.

Example 2: Unmarried partners utilizing a Tontine clause

A British couple buying a holiday home in the resort of Val Thorens opts for a tontine clause to ensure that if one passes away, the survivor automatically becomes the sole owner of the chalet, keeping the asset safe from external estate claims. Our office alerts them to the fact that, as an unmarried couple, the survivor will face a 60% taxation rate on the inherited share under French law, making additional estate planning highly advisable.

Example 3: Multi-generational wealth management via an SCI

A family establishes an SCI to purchase a luxury chalet in Alpe d’Huez. The parents gradually gift bare ownership (nue-propriété) of the company shares to their children every 15 years, taking full advantage of tax-free allowances. The parents remain the managers, retaining full operational control over the property while smoothly reducing their future estate tax exposure.

Example 4: Resolving an Indivision stalemate through Notarial Mediation

Following a relationship breakdown, two unmarried co-owners of a property in the region reach a complete standstill regarding the value of their shared home and how to split their assets. One partner wishes to buy out the other’s share but cannot agree on a fair price. By instructing a notaire, the parties benefit from an independent, legally recognized valuation of the property using the PERVAL database—a real-time network updated directly by authentic deeds signed across France.

Acting as a neutral mediator, the notaire drafts a formal buyout agreement (rachat de soulte) based on objective market facts, successfully resolving the dispute and saving both parties from an expensive, lengthy court process.

8. Which Structure Fits Your Project?

• Choose Indivision if: You want a low-cost, straightforward setup without administrative corporate overhead, and you are comfortable with standard unanimity rules for major property sales.
• Choose Tontine if: You are an unmarried couple looking to guarantee that the surviving partner automatically takes full ownership of the property, and you do not mind a rigid operational structure during your lifetimes.
• Choose SCI if: You are planning a long-term investment, want to optimize your property tax options, wish to avoid potential indivision blockages, and intend to pass shares down to your children over time.

Each real estate investment in France involves distinct financial, legal, and family variables. It is highly recommended to get in touch with a notaire who has deep knowledge of the French Alps real estate market to create a global, confidential analysis tailored to your personal situation.
