Genealogy Records

The Cook County Clerk's office provides non-certified copies of vital records for the purpose of genealogical research.


To order online, visit the Clerk's website Genealogy Online.

Please note, the Chicago Fire of October 8, 1871 destroyed all county vital records prior to that date.

Under Illinois law, genealogical records are defined as:

  • Birth certificates older than 75 years.
  • Marriage certificates older than 50 years.
  • Death certificates older than 20 years.

All genealogical records issued by the Clerk's office are considered non-certified documents and stamped "For Genealogical Purposes Only."

  Document   Cost
  Birth   $15; and $4 for each additional copy 
  Marriage   $15; and $4 for each additional copy
  Death   $17*; and $6* for each additional copy
  *Effective July 1, 2012 per PA 97-0679


If you are uncertain of the exact date of birth, marriage or death and want us to search more than one year, include $1.00 for each additional year you want searched, up to a maximum of 10 years.
