We are having a destination wedding with just our parents and my aunt and uncle. We've asked my aunt and uncle to sign our wedding cert. So, they have taken on the role of best man and maid of honor, right? I'm new to this and need to know what other things they should do so I dont step on any toes. For the most part they'll just be the attendants at the wedding only since we are not having a reception, bridal party, etc.
Don't worry about stepping on any toes. There really is no reason to have any attendants. They are signing as witnesses. You could simply ask them to stand with you as you are getting married.
