Please note that certain records may not exist in our files, as many records, especially those from the earliest available dates, were never recorded with the Will County Clerk.

Genealogical requests should be submitted in the same manner as requests for all Vital Records. Please see the specific page for instructions for requesting each record type:

We do NOT recommend using VitalChek for a genealogical research. VitalChek is an expedited processing and shipping service provided by a third-party partner that includes significant additional costs. Researchers may incur fees for searches through VitalChek for older records that do not exist. We recommend using VitalChek only for records the Will County Clerk’s Office is certain to have on file.
