If you are not marrying in your home parish, you will need a recent copy of your baptismal certificate to show you are free to marry in the Catholic Church. Interview with a priest or deacon. During this interview you will be asked if you are free to marry, and about your understanding of the commitment you are making and your ability to live it out. This is a good opportunity for you to ask questions, too. Learn about or perhaps help plan your wedding liturgy.
Local customs vary on who selects music, plans the liturgy and so on.
Your parish staff will tell you what the next steps are for you. Consult your parish staff for further guidance on each of these practical points. Thomas Richstatter, O.F.M., Th. D. , teaches sacramental theology at St. Meinrad School of Theology. His doctorate in liturgy and sacramental theology is from the Institut Catholique of Paris.
