Where I attended ceremonies (Romania, Switzerland) the priests will only marry you "officially" if you present them a civil marriage certificate, so ceremonies are usually arranged right after the visit to the city hall. I said "officially" because you'd surely find some willing monk if you elope, but I'm not sure even the church would afterwards recognize that marriage without some hassle.
