Following the death of our parents, my brothers and I became joint owners of a property located in a condominium. The general meeting of co-owners is due to be held soon. Can each of us take part in the vote, given that we don't get along?

No. When a condominium is held by undivided co-owners, the indivision as a whole is represented by a joint agent chosen by the undivided co-owners. In the case of a disagreement, the representative is appointed by the president of the court to which the matter has been referred either by one of the undivided co-owners or by the syndic (art. 23 al. 2 law n°65-557 of July 10, 1965).
