Italy is a very bureaucratic state and often the road to obtain all the documentation needed is long and tiring, having somebody in the country to help you out through this process will make everything easier and less stressful. To plan your wedding ceremony in Italy it is better to start 10-12 months in advance, as usually the more fashionable locations need to be booked one year before, especially for Spring or Summer Seasons. For the documentation needed for the Wedding Ceremony specifically, it is very important to not start too early as the documents will have a 6-month window of validity.
