Illinois marriage license guide

How to get a marriage license in Illinois

Illinois requires a one-day waiting period (the license is issued same-day but cannot be used until the next calendar day) and is valid for 60 days only in the county where issued. Fees vary widely — Cook County charges $60, smaller counties as little as $15. One witness is required. Illinois abolished common-law marriage in 1905; pre-1905 marriages and those formed in recognizing states are still honored.
