Last but not least…
What type of ceremony you have chosen for your wedding?
Civil, symbolic, or religious ceremony?
The documents you need for the paperwork have validation of just 3 months. Make sure that in the last 3 months before the wedding you have completed all the bookings, so you can focus on the paperwork and the last details.
For a symbolic ceremony wedding ideally, you can start the planning process 8-10 months.
For legal ceremonies (civil or religious) make sure you start a little bit earlier to have enough time for the paperwork… ideally 10-12 months before the Big Day.
