In short
Démembrement (split ownership) of a property means separating the usufruit (usufruct: occupying or letting the property and collecting the rent) from the nue-propriété (bare ownership: the bricks and mortar, which revert to full ownership when the usufruct ends). For tax purposes, the value of each right depends on the age of the usufruitier (usufructuary, the holder of the usufruct): the usufruct is worth 90% of the property before the age of 21 completed years, then loses 10 points for each ten-year bracket, down to 10% beyond 91 (CGI, code général des impôts (General Tax Code), art. 669). A fixed-term usufruct is worth 23% per ten-year period (same article). When the usufruct ends on death or at the end of its term, its reunion with the bare ownership triggers no tax (CGI, art. 1133).
Usufruct and bare ownership: who has which rights?
Usufruct is “the right to enjoy things owned by another, as the owner himself would, but with the obligation to preserve their substance” (code civil (Civil Code), art. 578). Service-public.gouv.fr summarises the division as follows:
| Right over the property | Full ownership | Nu-propriétaire (bare owner) | Usufructuary |
|---|---|---|---|
| Dispose of it (sell) | Yes | Yes, their bare ownership | No (they can transfer their usufruct) |
| Occupy it | Yes | No | Yes |
| Collect the rent | Yes | No | Yes |
The usufructuary can live in the property, let it, and even sell or give away their usufruct (art. 595). However, they cannot alone enter into an agricultural or commercial lease: they need the bare owner’s agreement or, failing that, a court authorisation. Residential leases of more than nine years that they sign alone are binding on the bare owner, when the usufruct ends, only for the nine-year period then running (art. 595).
The sale of full ownership requires the agreement of both. The price is then divided according to the respective value of each right, unless they agree to transfer the usufruct to the sale proceeds; and selling the property without the usufructuary’s agreement does not take away their usufruct (art. 621).
Who pays for what: upkeep, major works, taxes
The Civil Code draws the line: the usufructuary is only liable for maintenance repairs; major repairs remain the owner’s responsibility, unless they result from a failure to maintain (art. 605). Major repairs are those “to main walls and vaults, the restoration of beams and of entire roofs”, as well as of dykes and of retaining and boundary walls in their entirety; “all other repairs are maintenance” (art. 606).
On the tax side, service-public.gouv.fr states that the usufructuary of a property pays the taxe foncière (property tax) and, depending on the value of the property, the impôt sur la fortune immobilière (property wealth tax); if they let it, they are taxed on the rent. They must also draw up an inventory of condition before using a property.
The tax scale in article 669 of the CGI
For registration duties and the taxe de publicité foncière (land registration tax) (gift, inheritance, sale), the value of each right is a fraction of full ownership:
| Age of the usufructuary | Usufruct | Bare ownership |
|---|---|---|
| Under 21 completed years | 90% | 10% |
| Under 31 completed years | 80% | 20% |
| Under 41 completed years | 70% | 30% |
| Under 51 completed years | 60% | 40% |
| Under 61 completed years | 50% | 50% |
| Under 71 completed years | 40% | 60% |
| Under 81 completed years | 30% | 70% |
| Under 91 completed years | 20% | 80% |
| Over 91 completed years | 10% | 90% |
Source: CGI, art. 669, I. Example: a 65-year-old parent gives the bare ownership of a flat valued at €300,000 and keeps the usufruct. They are under 71 completed years: the bare ownership is worth 60%, i.e. €180,000, the basis for gift duties. On the usufructuary’s death, the child recovers full ownership with no further tax (CGI, art. 1133).
For a fixed-term usufruct, the age scale does not apply: the usufruct is valued at 23% of full ownership “for each ten-year period of the duration of the usufruct, without fractions and regardless of the age of the usufructuary” (art. 669, II). A twenty-year usufruct is thus worth 46%.
Where does split ownership come from?
Service-public.gouv.fr cites the most common situations: parents have the usufruct of the property of their children under 16, and the surviving spouse can receive the usufruct of the deceased’s estate, the children becoming bare owners. The Civil Code gives the spouse this choice when the deceased leaves children: the usufruct of all the property, or full ownership of a quarter where all the children are children of both spouses (art. 757). Split ownership can also arise from a will, a court decision or a contract: a gift or sale of a usufruct or a bare ownership.
Buying the bare ownership
Buying only the bare ownership means paying a fraction of the full-ownership price, giving up occupation and rent for the duration of the usufruct, then becoming full owner when it ends. If the usufruct is granted for a fixed term, article 669, II gives the tax basis: 23% per ten-year period for the usufruct, the balance for the bare ownership. When the usufruct comes to the end of its term, the reunion takes place free of any tax or duty (CGI, art. 1133).
During the split, the bare owner bears major repairs (art. 605 and 606) and must let the usufructuary occupy or let the property. Finally, service-public.gouv.fr points out that when the usufruct ends, a settlement of accounts determines what each owes the other, and that the usufructuary cannot claim any compensation for having improved the property.
FAQ
Can the bare owner sell the house without the usufructuary?
They can sell their bare ownership on its own. Selling full ownership requires the usufructuary’s agreement; failing that, the usufructuary keeps their usufruct (Civil Code, art. 621).
Who pays for replacing the roof?
Restoring an entire roof is a major repair, payable by the bare owner (art. 606), unless it results from a failure by the usufructuary to maintain the property (art. 605).
What is the usufruct of a 75-year-old worth?
30% of the value of the property, since they are under 81 completed years; the bare ownership is worth 70% (CGI, art. 669).
Are duties payable when the usufructuary dies?
No: the reunion of the usufruct with the bare ownership on the usufructuary’s death or on expiry of the term gives rise to no tax or duty (CGI, art. 1133), subject to article 1020.
Can the usufructuary let the property?
Yes, they can let it and collect the rent (art. 595). The bare owner’s agreement is only required for an agricultural, commercial, industrial or craft lease.
Which professional to consult
The notaire (the public official who drafts property deeds) draws up the split gift or sale and applies the article 669 scale. The agent immobilier (estate agent) provides the valuation of the full ownership, the basis for the whole calculation. The courtier en crédit (mortgage broker) can look into financing for a bare-ownership purchase.
