City of Chicago, I think we paid $65 for the license.
We don't get anything automatically after the wedding so when I call to request certified copies for insurance, social security, etc, I believe I need to pay a fee per copy.
Serenity, I believe it actually varies by county. I was married in Hartford county where it is 50. Not that it really matters too much. I don't know if other states vary by county at all, but Maryland seems to.
Ours is pretty rediculous...$150 in the city, $120 if you get it 45 minutes outside the city and $100 if you drive an hour to get it. I'm in Ottawa, Canada
