Mount Prospect Marriage Records
Mount Prospect marriage records are on file with the Cook County Clerk, not the Village of Mount Prospect. Many residents assume they can get a marriage license or a copy of a marriage certificate at the Mount Prospect Village Hall on South Emerson Street. That office handles village business, but marriage records fall under county control in Illinois. If you need to search for a marriage license, request a certified copy, or apply for a new license in Mount Prospect, the Cook County Clerk is the office to contact. The process is the same for all Cook County cities and villages.

Getting a Marriage License in Mount Prospect
Both people must show up in person at a Cook County Clerk location to apply. You cannot do this by mail. The fee is $60, and the office accepts cash, checks, and cards. An online pre-application is available on the Cook County website, which can save time at the counter, but you still have to go in to finish the process. Mount Prospect couples often use the Rolling Meadows suburban office since it is closer than the downtown Chicago location.
Each person needs a valid photo ID. A state ID, driver's license, or passport works. If either person was married before, bring a certified copy of the divorce decree or death certificate. Under 750 ILCS 5/203, both people must be at least 18. Applicants who are 16 or 17 need parental consent and a court order. No blood test is needed. There is no residency rule, so out-of-state couples can also get a license in Cook County. Once issued, a 24-hour wait kicks in before the license is valid. It then stays good for 60 days.
The license can only be used for a ceremony in Cook County. If Mount Prospect residents want to marry in a different county, they need a license from that county. After the ceremony, the officiant signs the license and sends it back to the clerk for recording. The marriage record then stays on file with Cook County permanently. Mount Prospect couples can request copies at any point after that.
Mount Prospect Marriage Certificate Copies
Certified copies of Mount Prospect marriage records come from the Cook County Clerk. The first copy costs $15. Extra copies in the same order are $4 each. These have a raised seal and work for legal use. You can request them at the Clark Street office or at the Rolling Meadows suburban branch. Mail requests are also accepted if you send a check made out to the Cook County Clerk with a self-addressed stamped envelope.
To request a copy, give the full names of both spouses and the date of the marriage. Under 410 ILCS 535/25, the Illinois Vital Records Act sets rules on who can get certified copies. The people named on the record, their children, parents, legal reps, or anyone with notarized consent can request them. Marriage records on file 75 or more years fall under less strict rules and may be available for genealogy work. The Cook County Genealogy Online portal has older records you can search for free.
The Illinois Department of Public Health can also verify a marriage for $5. This is not a certified copy. It just confirms the marriage took place. The IDPH covers records from 1962 forward. For marriages before 1962 in Mount Prospect, the county clerk is the only source.
The screenshot below shows the Illinois Department of Public Health marriage records page, which explains state-level options for verifying a marriage.
While the IDPH can provide a verification letter, most Mount Prospect residents will want a certified copy from Cook County for legal or personal use.
