I speak to many couples who tell me that they have a friend or a relative who is going to get a one day license to perform their marriage.  Do you really want to take a chance on an unprepared friend or family member who has never performed a Wedding?  

Marrying a couple requires training. Is your Wedding the right place to let Aunt Martha practice to be a Wedding Officiant? I hear horror stories of entire parts of ceremonies being skipped or performed incorrectly, using friends or relatives. If your friend or relative is a professional Officiant, then having them perform your Vows is an awesome idea.

However if they are not a professional, let me include Aunt Martha or Cousin Larry in your ceremony. They get to be an honored guest, enjoy your Wedding and not be responsible for running the whole show.
