What is Third-Party Notification Enrollment – Cook County, IL?
The Third-Party Notification Enrollment is the Cook County Treasurer's Office form used to designate another person or organization to be contacted if the applicant's taxes become delinquent. The Treasurer's website presents it as the Application for a Third Party Notification Request.
The form is tied to one property. It asks for the Volume and Property Index Number (PIN), the owner's name, the property address, and the owner's e-mail and phone. A second block collects the name, organization, address, e-mail and phone of the notification party.
What it does is stated in the form: if the owner's taxes are ever published for tax delinquency and may be offered at tax sale, the Treasurer's Office will also notify the named party, in addition to the standard notices the owner would receive.
The form also sets limits. Third-party notification enrollment is designed for family members or relatives, not mortgage companies or banks. The owner is entitled to notice of delinquency only as prescribed by state statutes. The request is not a contract with the Cook County Treasurer's Office, and if the Treasurer does not honor it, the taxes can still be sold if they become delinquent. A new enrollment supersedes any earlier third-party notification authorization on file for the same PIN and property.
Who needs to file Third-Party Notification Enrollment – Cook County, IL?
Owners of Cook County property who want a family member, relative or another trusted person or organization to be notified if their taxes become delinquent complete this form. The form says that the person signing is the owner, or an authorized agent or power of attorney for the owner.
Points the form makes about who the notification party should be:
- The enrollment is designed for family members or relatives.
- It is not designed for mortgage companies or banks.
Keep in mind that the form covers one property, identified by its Volume and PIN. An owner who has already named a notification party for that PIN can submit a new form: the new authorization replaces any previous one on file for the same PIN and property.
The form does not create a right to more notice than the law gives. The owner remains entitled to notice of delinquency only as prescribed by state statutes.
When to file Third-Party Notification Enrollment – Cook County, IL
The form refers to a future event: taxes that are ever published for tax delinquency and may be offered at tax sale. It prints no due date of its own, so an owner submits it whenever they want a contact named for that property, as the form is about who is notified if delinquency happens.
If you later want to change the person or organization on file, submit a new form for the same PIN: it supersedes any previous third-party notification authorization the Treasurer's Office holds for that PIN and property. The form states that the Treasurer's failure to honor the request will not prevent taxes from being sold if they become delinquent, so the enrollment does not replace paying taxes on time.

- Mailing the form without a signature and date; the owner's certification is made by signing.
- Having someone sign who is not the owner, an authorized agent or a power of attorney for the owner.
- Treating the enrollment as a contract or a guarantee; the form says it is not a contract and the taxes can still be sold if the Treasurer does not honor it.
- Expecting notice beyond what state statutes prescribe; the owner is entitled only to notice of delinquency as the statutes provide.
- Forgetting that a new form supersedes any previous third-party notification authorization on file for the same PIN and property.
- Leaving off the Volume or Property Index Number (PIN), the entries that identify the property.
- Mailing the form to a different room or address than the one printed on it: Cook County Treasurer, Third-Party Notification, 118 N. Clark Street – Room 112, Chicago, IL 60602.
