Cook County Vital Records
The Cook County Clerk's office is the official record keeper for births, marriages, civil unions and deaths that occur in Chicago and suburban Cook County. Cook County Vital Records provides copies of these documents to eligible individuals upon request.
Cook County Vital Records also offers specialty certificates for marriages and civil unions. Commemorative certificates are art-quality canvas certificates in a frame-ready size. Wallet certificates are ideal for carrying in your wallet or pocket as proof of your union.
In addition, Cook County Vital Records maintains a genealogy website, certifies notary public commissions approved by the Illinois Secretary of State, and registers the assumed names of businesses.
