I am in joint ownership (indivision) with my brothers over a real estate property located in Corsica, following the death of our mother. I understand that if my brother buys out our shares, we may be exempt from the partition duty. Is this correct?

Reminder: The partition duty is levied by the French tax administration when co-owners agree to terminate the joint ownership by allocating the jointly owned property to one of them. Except in specific cases, this duty is set at 2.5% of the net value of the assets being divided.
Answer: Yes. Article 750 bis B of the French General Tax Code provides for an exemption from the partition duty, subject to the following conditions:

The partition must benefit members originally part of the joint ownership, their spouses, ascendants or descendants, or the universal beneficiaries of one or more of them;
The transaction must take place between 1 January 2017 and 31 December 2037;
The property being divided must be located in Corsica.
