In Lambertville, N.J., the marriage certificate of Beth Asaro and Joanne Schailey allowed only for a “bride” and a “groom,” so Ms. Asaro — in a pink suit — was listed as the groom, and Ms. Schailey — in a black suit — as the bride.

The same went for the marriage license application that Karen and Marcye Nicholson-McFadden filed in Aberdeen a few hours before they were due to marry on the Boardwalk in Asbury Park a minute after midnight. “It’s just going to list one of us as groom and one of us as bride, and we’re just going to wing it,” Marcye Nicholson-McFadden said breathlessly.

And in Elizabeth, Marsha Shapiro’s walk down the aisle was only minutes away when she realized she had forgotten something very important — or two somethings. “We need a ring bearer,” she said, as bottles of Champagne popped around her. “And I need to put my lipstick on.”

So it went on Sunday night in towns across New Jersey, where a judge’s ruling that the state must allow same-sex couples to marry went into effect just after midnight on Monday, capping a weekend-long frenzy of flower-arranging, Champagne-spraying, hair-styling, ring-buying and cake-baking. The six women were some of hundreds of people who rushed to make wedding arrangements over the weekend, after the State Supreme Court denied on Friday a request from the administration of Gov. Chris Christie for a stay on marriages until an appeal was settled.
