Eight gay and lesbian couples on Wednesday filed a lawsuit seeking Missouri recognize their out-of-state marriages.

The couples – two of which are men – are represented by the American Civil Liberties Union (ACLU) of Missouri.

“Because of the many benefits of marriage, Missouri has traditionally recognized lawful marriages performed in other states,” said Jeffrey Mittman, executive director of the ACLU of Missouri. “We know that the people of Missouri are fair-minded and did not intend to harm these eight families and other like them throughout Missouri. But our current laws do harm them.”

Voters in 2004 overwhelmingly (71%) approved Amendment 2, which prohibits same-sex marriages from being performed or recognized in Missouri.

Wednesday's lawsuit, filed in state court in Jackson County, does not seek full repeal of Amendment 2.

Plaintiffs Janice Barrier and Sherie Schild of Olivetter married in 2009 in Iowa. They women were introduced by a mutual friend in the summer of 1981.

Now in their 60s, they worry about their future together.

“We're really concerned that if one of us would end up in a nursing home we might not have the same rights to care for each other in privacy that different-sex married couples enjoy in Missouri,” Barrier . Told Kansas City's KMBC-TV. “It's so very important to us that we're not torn apart at the very end of our lives.”
