A church wedding calls for a few more documents than a civil one. First, you’ll need a certificate proving you’ve completed a premarital course—a prerequisite for submitting your birth and residence certificates as a couple.
Next comes a second set of church-specific documents: certificates of baptism and confirmation; a Church freedom-to-marry certificate (stato libero ecclesiastico); and an ecclesiastical clearance (nulla osta) if you plan to marry outside your home parish. While the baptism and confirmation certificates show you’ve received those sacraments, the freedom-to-marry document proves you haven’t been married before in the Church, and the ecclesiastical clearance authorizes a wedding in another parish.
Finally, you must publish the marriage banns—official announcements confirming there are no objections to your union. These banns allow the parish priest to grant religious consent at the end of the ceremony. After the wedding, you receive an official marriage certificate, a copy of which the church forwards to the municipality where the ceremony took place.
