Dismemberment of ownership — an ancient civil law concept in the service of modern wealth planning

The dismemberment of property finds its source in Article 578 of the French Civil Code: usufruct is the right to enjoy things belonging to another person, subject to preserving their substance. Full ownership therefore splits into two distinct rights — usufruct (right of use and enjoyment) and bare ownership (right of disposal) — which naturally reunite upon extinction of the usufruct.

While viager dismemberment (linked to a person’s lifetime) is the best-known form, it is fixed-term temporary dismemberment that attracts sophisticated investors today. In this structure, an institutional usufructuary — a social housing organisation, a specialist operator or an intermediate housing provider — acquires the usufruct of a property for an agreed period, typically 15 to 20 years. It lets the property, collects rents, handles maintenance and manages vacancy. The investor purchases only the bare ownership at a price necessarily lower than the full ownership value.

The principal operators in the French market include CDC Habitat (subsidiary of Caisse des Dépôts), ICF Habitat, Batigest, and specialists such as PERL and Kyaneos. The quality of the dismemberment depends critically on the financial solidity of the usufructuary — a social housing organisation backed by a public guarantee is infinitely preferable to an unrated private operator.

The acquisition discount — fiscal calculation and market reality

The discount applied to bare ownership results from the value attributed to the temporary usufruct, assessed in accordance with Article 669 of the General Tax Code. For a fixed-term usufruct, the fiscal value is 23% of full ownership value per started 10-year period. Therefore, a 20-year temporary usufruct is fiscally worth 46% of full ownership — and the corresponding bare ownership, 54%.

In practice, market discounts incorporate an additional risk premium reflecting capital lock-up and uncertainty over the property’s future value. Investors actually transact at:

The financial mechanics are compelling. Consider an apartment valued at €500,000 in full ownership, acquired as bare ownership on a 17-year dismemberment at 61%: you invest €305,000. If the property appreciates modestly at 2% per year in nominal terms, it will be worth approximately €685,000 at extinction. Your gross gain amounts to €380,000 on €305,000 invested — a total return of 124%, generated entirely without a single euro of taxable rental income during the period.

Triple tax shield — rental income, IFI and capital gains

Zero rental income during the dismemberment

The bare owner receives no rent — it belongs to the usufructuary. Consequently, no rental income is taxed during the entire dismemberment period: neither income tax (flat rate of 30% or marginal rate up to 45%) nor social levies at 17.2%. For an investor in the 45% marginal tax bracket, the annual saving compared with a conventional buy-to-let generating €15,000 of gross rent exceeds €9,000 per year — more than €135,000 over 15 years, compounded.

Full IFI exemption

This is arguably the most decisive advantage for taxpayers subject to the real estate wealth tax. Under Article 968 of the General Tax Code, the usufructuary alone is liable to IFI on the total full ownership value of the property. The bare owner declares nothing — their bare ownership falls entirely outside the IFI base for the duration of the dismemberment. For investors with an already substantial property portfolio, bare ownership enables capital to compound structurally without further increasing IFI exposure.

Favourable capital gains allowances

Upon sale after extinction of the dismemberment, the capital gain calculation takes the original date of bare ownership acquisition as its starting point. Duration allowances under Article 150 VC of the General Tax Code therefore apply from that original date: 6% per year from year 6 to year 21 for income tax (19%), and 1.65% per year from year 6 to year 21 for social levies (17.2%). For a property acquired in bare ownership in 2026 on a 17-year usufruct, a sale in 2043 will benefit from substantial allowances, reducing the effective combined rate well below the nominal 36.2%.

Bare ownership vs buy-to-let vs SCPI — the decision dashboard

A rational comparison of these three approaches must integrate not only headline returns but also the full tax burden, administrative load and the risks associated with property management.

The table illustrates the singular risk/return profile of bare ownership: no current income, but structural appreciation guaranteed by the initial discount, without any management burden or annual tax exposure. The investor is essentially buying a real estate zero-coupon bond — an instrument that compounds without distributing, ideally suited to portfolios already generating substantial income from other sources.

Key risks and success factors

Beyond these three principal risks, the condition of the property at the extinction of the dismemberment deserves close attention. The usufructuary is required by Article 589 of the Civil Code to return the property in good working order. Institutional bare ownership contracts include guarantee clauses and sometimes provision for works upon exit. Read these clauses carefully before signing. Finally, location remains paramount: central Paris, Bordeaux, Lyon and the Mediterranean coast (Nice, Cannes, Antibes) are the markets where long-term appreciation is most predictable.
