Marriage licenses are issued in person by the county clerk in the country in which the couple will be married. The couple must visit the clerk's office together, present
valid forms of identification, and pay a marriage license fee (currently $60 in Cook County). They are issued while you wait, are effective the day after they are issued (you can't get married the same day), and are valid for a period of sixty (60) days. In Cook County, couples may complete a marriage license application online, but still must appear in person to finalize the application process.
