Well, it all depends on them. First, you can seat them at totally different places at the reception. This will keep their interaction down to a minimum hopefully. Second, you can talk to them about it prior to the wedding. Sit down with both of them individually and tell them that they need to behave for that one day. Make sure your fiance is the one to talk to them, but be there to support him. Tell them that you (meaning your fiance) really want both of them there to support him on one of the biggest days of his life. Hopefully they can put aside their differences for one day. Good luck!

I'm getting married in June and I'm having my father sit on my fiance's side. My parents also can't stand eachother. I also let them know that this is our wedding day and not their's and they need to respect it. Plus, my brother is a very big protective brother and will escort my dad if he causes any problems! :) Just let them know that this is your day and they had theirs. I hope all works out.
