All filings must contain the required attachments listed below, unless not applicable (exempt from taxation properties). 

• Attach a completed Continued Use Affidavit form (available from the Assessor’s Office) if exemption on any new parcel should continue. We will process a division/consolidation request impacting an Exempt status parcel without this form accompanying it.
• Attach recorded warranty deeds showing ownership of all parcels to be divided.
• Attach individual legal descriptions of all parcels to be divided. The Map Department of the Cook County Clerk provides non-certified legal descriptions for a fee.
• Attach legal descriptions of all new parcels desired. Each new legal description must be labeled with the tract number that corresponds to each owner’s signature.
• Attach a plat of survey showing acreage if the division involves metes and bounds legal descriptions.
• Attach a survey for legal descriptions using horizontal elevations. All elevations must refer to Chicago City Datum (CCD).
• Attach a completed Plat Act Affidavit if:
  • the existing property is not subdivided, and
  • any desired new parcel of land will be smaller than five (5) acres, but
  • the owner of the existing property is not required by law to record a plat of subdivision with the Cook County Clerk Recording Division.
  • If a division is required for a Condominium, Subdivision, or any other recorded document, you must file one (1) original document plus seven (7) copies with the Cook County Clerk’s Recording Division.
• All filings must be complete in both submission contents and fees at the time of submittal unless it is submitted via email.  Due to staffing constraints on the importance of placing new parcels on the assessment rolls, CCAO Division Staff may only contact you once as a reminder of missing documentation, errors in the filing, or fee issues.  It is the responsibility of the filer to make sure their submission is complete; if the submission is incomplete or in error and the filer does not resolve any issues with the Divisions Department promptly after contact, that filing is subject to be rolled over to the next assessment year and/or canceled.
• If submitted by email, you have 5 business days from the invoice date to submit payment on your filing.
