Michigan says it will wait for a Supreme Court ruling in a case challenging gay marriage bans in four states before altering marriage forms, but several clerks say they're prepared to act on their own.

Michigan is among the four states involved in the case. Heard in April, a ruling is expected at any moment and could lead to nationwide marriage equality.

Jennifer Smith, spokeswoman for the Michigan Department of Health and Human Services, said that decisions would not be finalized until after the ruling and she wouldn't commit to saying how long the process might take.

“Right now, we're waiting for the court ruling,” she told The Detroit Free Press. “Any changes necessary to the marriage license form would be reviewed and finalized after the ruling.”

“We're just waiting for the court to make its decision and we'll move forward from there,” she added.

Barb Byrum, clerk of Ingham County, promised to move faster.

“I will only wait for it to be legal,” she said, “I will not wait for direction from the attorney general or any such individual. I will wait for the court to decide and go from there.”

Macomb County Clerk/Register of Deeds Carmella Sabaugh said that her office would alter the wording on the form if the state does not provide updated forms.

Kalamazoo's county clerk, Timothy Snow, said his office was “as ready as we can be.”
