How the Apostille Process Works for Cook County Documents
Cook County is the most populous county in Illinois, and the volume of document requests from this area is the highest in the state. Documents issued by Cook County agencies must be authenticated through the Illinois Secretary of State in Springfield before they can receive an apostille.
