Hi,My father and his four sisters, who

Hi,My father and his four sisters, who are all Italian citizens, have recently inherited a property in Italy. Sadly there is a dispute regarding the property. The dispute surrounds the four sisters who want to sell the property, but my father does not want to sell, as he wants to keep the property in the family. They all have an equal share of the property. My question is, in Italian law, can the property be sold as there is a majority i.e. four to one in favour of a sale, or does everyone need to agree before the property can be sold? Your guidance would be very much appreciated.Kind regardsGiovanni
