The online marriage application must be completed before the couple comes to the office. Marriage licenses are issued Monday to Friday 8:00 a.m. to 4:00 p.m. only, and no appointment is necessary. Licenses become effective the day after they are issued and the Clerk states plainly that it cannot waive the one day waiting period. A license issued in DuPage County cannot be used in any other county, state or country, so couples must confirm the venue address falls inside DuPage. The physical license is handed over at the counter, but it does not become effective until the next day.
