Eight gay and lesbian couples on Thursday filed a federal lawsuit seeking Florida recognize their out-of-state marriages.

The couples are represented by the American Civil Liberties Union (ACLU) of Florida.

“Each of these couples has their own story of how the state's discriminatory refusal to recognize their marriages has impacted their lives,” Daniel Tilley, attorney for the ACLU of Florida, said in a statement. “These eight couples have all the rights and responsibilities of marriage in the states where they exchanged vows, and the federal government recognizes their marriages as well. It's time for Florida to stop the harmful practice of treating committed couples as if they are strangers.”

Plaintiff couple Christian Ulvert and Carlos Andrade were married in Washington, D.C. in 2013. The couple, together four years, lives in Miami and is considering starting a family.

The lawsuit asks a judge to force Florida to recognize their marriages.

Florida's 2008 voter-approved constitutional amendment limiting marriage to heterosexual couples is being challenged in a lawsuit filed earlier this year.

Similar suits asking for recognition have been filed in Kentucky and Missouri.
