A marriage license is both the first step towards getting legally married in Illinois, as well as a document that confirms the legal marriage between two persons.
In order to get married, you and your partner must first apply for a marriage license together at an approved location BEFORE solemnizing the marriage, which requires the following:
presenting identification with proof of your age
filing out and signing a marriage application form; and
paying a $60 filing fee, unless you qualify for a fee waiver
