Washington state's historic same sex marriage law took effect at midnight and moments after that, the first couple took their vows.
About 140 same-sex couples are getting married at Seattle's City Hall on Sunday - the first day weddings can take place.
Public school elementary teachers Sarah and Emily Cofer were the first to get married at midnight at the King County Courthouse in Seattle. The couple has been together for 10 years.
Judge Mary Yu conducted the ceremony while several cameras clicked in the background.
Eleven other couples got married overnight. Each waited to take their vows at 30-minute intervals with Judge Yu.
Marjorie Lynn and Susan Hopkins finally know what it feels like during those last few moments before tying the knot.
"I am nervous but very excited," said Hopkins as she checked to make sure she had the ring and a crumpled copy of her vows. "I'm so happy."
It's not like their lives will dramatically change. The two said they woke up Sunday morning the same way they have for the last 16 years, together, in love. But weddings were always something for their straight friends, an experience they could only watch from the outside.
It was the same story for the other 139 couples welcomed to say their vows at Seattle City Hall on Sunday. There were individual wedding settings set up all over the building. Applause burst out after each "I do."
Outside, hundreds of well wishers applauded couples they have never met and showered them with support, rice and flowers.
Washington voters approved Referendum 74 in November with 54 percent of the vote. The measure asked voters to either approve or reject the state law legalizing same-sex marriage that legislators passed earlier this year.
The law took effect on Thursday, but state law says couples have wait three days to marry after picking their marriage licenses.
Mayor Mike McGinn said opening city hall on Sunday underlines that the city stands behind the partnership of same-sex couples.
