The County Clerk and Recorder’s Office has five major functions: 
(1) Clerk of the County Board and Keeper of the County Records, 
(2) Chief Election Officer for Ogle County, 
(3) Keeper of Vital Records (Births, Civil Unions, Marriages and Deaths), 
(4) Computation of Property Taxes and Redemption of Delinquent Taxes,
(5) Record and maintain all Land Transactions for Ogle County.

The Recorder’s office maintains the index and records of all property transactions. All real estate documents, corporation papers, city and village ordinances and other miscellaneous documents, together with all servicemen/women’s separation and discharge papers, are recorded. The original document is returned to the individual presenting it for recording.

Mechanics’ liens and notices of tax liens, both federal and state, are filed, and the original is retained in a permanent file in the office. Financing statements, indicating liens on chattel property and termination statements thereof, are also filed.

Each document is assigned an official document number at the time it is presented for record and indexed for quick reference for record retrieval.

The Illinois Real Estate Transfer Act is administered through the Recorder’s office. 

In Ogle County, the Recorder also maintains a Book and Page Index of real estate transactions, which indicates the title to the property and any mortgages or liens against it. The chain of title may be traced back to 1837 and the original government grant in these indexes.
