«"Alexis, I'd like to give an apartment to my children to reduce their future inheritance taxes, but I can't afford to lose the rent I receive. What can I do?"»
This issue is central to wealth management engineering. The answer lies in a powerful and age-old legal mechanism: the division of ownership.
At the house of Balmont Conseil, We use this lever as a true keystone of your transmission strategy. As an Augmented Asset Engineer, my mission is to make this technique accessible and to orchestrate it so that it serves your protection and...'tax optimization.
What is the division of ownership rights?
The division of ownership rights is a legal optimization strategy based on the division of property rights, a concept inherited from Roman law. In French law, the <b>full ownership</b> The rights of an asset should not be seen as an indivisible block, but as a bundle of three distinct prerogatives:

Why resort to Split of ownership? Key advantages
Split of ownership is not just a legal concept; it is a tool of estate planning with multiple benefits.
A low-cost transfer of assets
By carrying out a gift with reservation of usufruct, You give the bare ownership to your children while retaining the use of the property.
- The tax benefit: Gift taxes are calculated only on the tax value of bare ownership (which is a fraction of the total value depending on the age of the usufructuary).
- The tax allowance on gifts: You benefit from the legal allowances (€100,000 per parent and per child every 15 years) on a reduced taxable base.
Protection of the surviving spouse
In the case of an inheritance, the surviving spouse in usufruct can remain in the family home and receive investment income, guaranteeing their standard of living, while the children are bare owners.
Optimized taxation (Wealth Tax and Income Tax)
The bare owner is not taxed on the income (since they do not receive it). Furthermore, in the context of a split ownership arrangement, it is generally the usufructuary who is liable for the French Real Estate Wealth Tax (IFI) on the full ownership value of the property.
How does land consolidation work?
THE property consolidation is the culmination of a split of ownership strategy. It is the legal and patrimonial moment when the usufruct (the right of use and receipt of income) merges with the bare ownership (ownership of the building) to reconstitute the full ownership in the hands of the bare owner.

Practical applications: Investment examples
Obligations and allocation of costs
There management of split assets imposes a precise distribution of rights and duties as defined by the Civil Code:
- The usufructuary: He must ensure routine maintenance and pay for charges and repairs Say "maintenance". He also pays the property tax.
- The bare owner: He is in charge of "major repairs" (retaining walls, vaults, complete roofs).
Balmont's expertise: To avoid any conflict between heirs, We recommend drafting a customized ownership division agreement to arrange this distribution.
What are the tax advantages of splitting ownership rights?
The division of ownership rights is one of the most powerful tax tools for transferring assets. Its effectiveness rests on a simple principle: reduce the taxable base while retaining the property's income.
A reduced taxable base thanks to the tax scale
In a gift with reservation of usufruct, gift taxes are not calculated on the total value of the property, but only on the value of the bare ownership.
👉 This value is determined according to an official tax scale based on the age of the usufructuary (article 669 of the French General Tax Code):
- Under 21 years: usufruct 90 % / bare ownership 10 %
- Ages 21 to 30: usufruct 80 % / bare ownership 20 %
- Ages 31 to 40: usufruct 70 % / bare ownership 30 %
- Ages 41 to 50: usufruct 60 % / bare ownership 40 %
- Ages 51 to 60: usufruct 50 % / bare ownership 50 %
- Ages 61 to 70: usufruct 40 % / bare ownership 60 %
- Ages 71 to 80: usufruct 30 % / bare ownership 70 %
- Ages 81 to 90: usufruct 20 % / bare ownership 80 %
- Over 91 years old: usufruct 10 % / bare ownership 90 %
👉 The younger the donor, the more important tax optimization becomes.
Concrete example of tax gain
Let's take a simple case:
- Property value: €500,000
- Donor aged 65 → bare ownership = 60 %
👉 Taxable base = €300,000 (instead of €500,000)
By applying the parent-child allowance of €100,000:
- Final taxable base = €200,000
👉 Result:
- Without split of ownership: taxation on €500,000
- With split of ownership: taxation on €200,000
➡️ A massive reduction in gift taxes
| Situation | Taxable base | Taxation |
|---|---|---|
| Without split of ownership | 500 000 € | High |
| With split of ownership | 200 000 € | Greatly reduced |
The tax savings can amount to several tens, or even hundreds of thousands of euros.
A tax optimization with a double effect
The split of ownership is not limited to an immediate reduction:
1. Freezing of tax value
👉 The taxes are calculated at the time of the gift
👉 All future appreciation of the property is tax-exempt
2. Tax-free transfer through land consolidation
👉 Upon termination of the usufruct (death or end of the period):
- The bare owner regains full ownership
- Without paying any additional fees
Key points to remember
The division of ownership rights allows for:
- Reduce the taxable base immediately
- Anticipating transmission
- Avoiding taxation on future valuation
- Transferring assets with minimal tax costs
It is an essential lever for any optimized wealth management strategy.
