My husband & I got married in a registry office in England. The minimum time our office would allow (and methinks it is universal) is 2 weeks from when you ask to ceremony date, because they "post" your intention to marry for 2 weeks, or something like that. ANYWAY, once you're married you're married, and we walked away with the license. Then went back to America a few months later and had the big wedding show, but it was just a vow renewal ceremony. But we did vows, rings, flower girls... the whole 9 yards. Both weddings were really lovely, and a registry wedding can be really, really nice.
