Once again, it is best to break down the larger issue into smaller components. If you do your research and planning carefully, arranging your ceremony can be a fulfilling, pleasant, and even a spiritual experience. Begin by deciding the type of ceremony you wish to have. Whether you want the ceremony to be held by a Village or Town Justice of the Peace, clergy person, or other officiator, find and reserve that person early. If you have a civil ceremony , most justices are open to performing the ceremony in any number of different kinds of locations, as long as it is within their and your State.
Different states require different licensure and have different legal requirements.
Discuss the parameters and requirements of such a service with your officiator. Practicing Catholics tend to prefer the former. Once that decision is made, the parameters are fairly well laid out by tradition. Changes and additions may be made, but the priest is the final arbiter of what is and is not appropriate. There are a variety of interpretations for this tradition, just one of which is the addition to every happy event, a bit of sadness that recalls the destruction of the Temple in Jerusalem.
