So a little background, FI and his family are Catholic and my family and myself are Mormon. FI said his priest wouldn't marry us because I'm not Catholic but my Bishop said he would do what my church calls a civil marriage (one done outside the temple) and that he would do it for free. Since neither one of us cares who performs the ceremony, we decided that free was the best option and were planning on having my Bishop perform the wedding.
Last night FMIL asked if we could get a JP to perform the ceremony, to keep it neutral for religion since we are different religions. I don't have a problem with a JP performing the ceremony, I have a problem with the cost. We have a budget but are trying to stay under it. I just don't like that she wants us to pay for a JP when we had someone lined up that was free so we didn't put that in the budget, we were planning on getting my Bishop and his wife a gift certificate to a restaurant for a night out but a JP will be a lot more then the thank you gift we were planning.
Should I fight FMIL on this since we are paying for our wedding, or should I just suck it up and cut from someplace else to pay for a JP? I like FMIL and we get along well but this irks me. We have a small budget to begin with and I've already moved the ceremony to during the day followed by a brunch reception with no dj/dancing and limited decorations and flowers to cut the budget that I don't really want to cut it more to pay for a JP.
I want to stress that I'm only oppose to a JP because of cost, if FMIL paid for it I would be fine with a JP instead of my Bishop because then it would be free again.
