Illinois Marriage License Requirements
In Illinois, couples seeking a marriage license must present a government-issued photo ID and proof of age. The state does not impose a residency requirement, though the marriage ceremony must take place in the same county that issued the license. Applicants must be at least 18 years old to marry without consent. Those aged 16 or 17 may marry with parental consent, while individuals under 16 are not permitted to marry. A blood test is not required.
Two witnesses aged 18 or older must be present at the marriage ceremony. The marriage license becomes valid one day after issuance and is only valid within the issuing county. The license fee is set by the individual county. Couples should confirm all current eligibility requirements and procedures with the county clerk's office in the county where they plan to marry, as requirements may change, and the clerk can provide guidance specific to their circumstances.
