Can I pick somone else to be my witness at my wedding instead of my maid of honor?

I am getting married next year. My maid of honer is my sister. I didn't want her to be my maid of honor but she threw a hissy fit because I didn't pick her originally. I picked my best friend first but my sis got upset so I picked her.I luv my sisters kids to death. So I picked the older two to be the flower girls %26amp; they are counting the days to my wedding. Last week I found out from my sis that she does not like my fiance one bit. When I my fiance %26amp; I were having issues in the past I confided in her. My fiance confided in his family too. His best friend who is his best man was against our relationship so was my sister. Now my sis %26amp; his best friend are the best man %26amp; the maid of honor. I don't want my sis to be a witness at my wedding so I chose my fiances uncle %26amp; my fiance wants his father to be the other witness. But my mom says usually the parents or the siblings don't be a witness. Is that true? Because I don't want my sis or his best friend to be a witness. I am catholic.

Can I pick somone else to be my witness at my wedding instead of my maid of honor?
sweet heart this is YOUR wedding you let your sis. throw a hissy fit and pick whom U want as your maid of honor and as your witness. don't let the tantrum trap you, you will regret it forever. think about it. what right does she have being your maid of honor (is she standing beside you?, happy for you? NO) I say go with the best friend and if you can't then yes pick best bud as witness. And if I were you I would make up a new title for my b-friend "Lady in Waiting" and have her come out right after you. That way your sis is still the maid of honor but only on paper. And you get to enjoy your wedding because it is Your day.
Reply:On our marriage license, we had both of our mothers sign. But it can be anyone there.
Reply:You poor thing! Your sister should be ashamed of herself. My sister and I are very close, but I chose to have my best friend be my maid of honor and my sister was a brides maid. She never said a word about it if she was upset by this. It is not to late to change your plans and have your wedding day be what you and your fiance' want it to be! As far as the witnessing goes, do what YOU want. If it is a problem with the preist/church then they will inform you, but I don't know why it would be. It is your day! Don't be bullied or pressured my insensitve family members.
Reply:you can pick anyone you want to because this is your day
Reply:You can pick whoever you want. Just because something isn't normal doesn't make it wrong. My moom was a witness because my maid of honor was a minor, she couldn't sign. Congratulations and good luck





P.S. my wedding was Catholic too
