What is the rules for a redo wedding? Is it the same as the first wedding? We had a bad wedding day and decided to redo it.

There are no set rules for redo weddings. This is the time for your true creative loving selves to shine! This is the time to really show your love for your spouse. Have fun. Invite whoever you wish. Disinvite whoever you wish. Have a reception for as long as you wish after the ceremony. Enjoy each other as this time you'll do it right (the wedding that is).

If it's been less than years (which would make it an anniversary renewal instead of a do-over), the only change would be no gifts.

Otherwise, Twinkie's right. Enjoy!

Aside from the great advice you have been given I would say no attendants either,unless you have children that you want to be involved.
You don't need an official pastor so you could have a close friend officiate for you,if you choose to have anyone officiate at all.
You can also really mix it up when it comes to the vows! Have a wonderful time!
