Cook County FAQs
Can I view deed images online for Cook County?
You can typically search the recorded documents index online by name or number; image downloads may require an account or purchase, and certified copies must be requested from the recorder.
How do I find the parcel number if I only have an address?
Use the assessor’s parcel search by street address to retrieve the parcel number, then use that identifier in recorder and tax searches.
Which office handles property taxes versus assessments?
The treasurer/tax collector maintains bills and payment history; the assessor maintains ownership reference, characteristics, and assessed values.
Are online records official for legal use?
Online data and images are useful for research, but certified copies from the issuing office are required for legal or official use.
