How to get a document notarized for someone in Cook County Jail

Find the person's booking number, get the document ready but unsigned, confirm with the jail (or the person's attorney) how an outside notary visit and the paperwork must be scheduled, make sure the person's ID is available, then book a mobile notary. Since 2023 the Cook County Sheriff's office has restricted visitors from bringing paper into the jail, so plan ahead.

Why jail notarizations take planning

Cook County Jail is run by the Cook County Sheriff's Office at 2700 S. California Ave. in Chicago. Families need notarized documents for real reasons: a power of attorney so someone can pay bills, a vehicle title, a lease, guardianship papers for children, or an affidavit for a court case.

The notarization itself takes a few minutes. Getting the notary, the document and the ID into the same room is the hard part. Every facility sets its own rules, and those rules change. No notary can promise access to a jail, and I won't pretend otherwise.

What I can do is explain the process honestly, show up with my journal and seal when the visit is approved, and handle the notarization correctly. My jail notary service page covers pricing and what I bring.

How to get a document notarized at Cook County Jail, step by step

  1. Find the person and their booking numberUse the Sheriff's online Individual in Custody Locator or call the jail's information line at 773-674-5245. Write down the full name exactly as the jail has it, the booking number and the housing division.
  2. Get the document finished, but unsignedAll blanks filled in, every page present, signature lines empty. If it's a legal document, have the person's attorney or the party requesting it prepare it. I can't fill it in or choose the form.
  3. Ask how an outside notary gets inCall the jail, or better, ask the person's defense attorney or public defender. Ask how a notary visit is approved, when it can happen, and how the paper document must be submitted ahead so staff can inspect it.
  4. Sort out identificationThe signer needs government-issued photo ID that's valid at the time of signing. Their ID is often in their property from booking. Ask whether staff can make it available for the visit. A jail wristband usually isn't enough; see my Illinois notary ID guide.
  5. Arrange witnesses if the document needs themSome documents, like a power of attorney for property, need a witness as well as a notary. The witness has to be approved to enter too, so ask about that at the same time.
  6. Book the visit with meCall (708) 787-8868 with the booking number, the facility's instructions, the document type and the number of signatures. I'll quote the total before I go.
  7. Sign, notarize, and get the document outThe person signs in front of me, I complete the certificate and record it in my journal. Ask in advance how the signed original leaves the jail: with me, with the attorney, or by mail.

What to have ready before you call me

  • The person's full legal name and booking number.
  • The name of the jail and division, plus whatever the facility or attorney told you about scheduling.
  • The finished document, unsigned, and how many signatures need notarizing.
  • Where the person's ID is, and whether it's current.
  • The name of any witness who will attend.
  • Who will receive the signed original afterward.

Documents families commonly need notarized at a jail

  • A power of attorney for property, so a family member can manage bank accounts, bills, a lease or a car. In Illinois it needs a witness and a notary.
  • A vehicle title transfer or a letter authorizing someone to pick up a vehicle.
  • Consent or guardianship papers for the person's children, usually prepared by an attorney or the court.
  • Affidavits and sworn statements for a court case, prepared by the person's attorney.
  • Bank, insurance or employer forms that the institution says must be notarized.
  • Whatever the document, the same rules apply as anywhere else. The signer needs valid ID, must understand what they're signing, and must sign willingly. See what a notary can and cannot do.

Do you really need a notary?

Before you go through all of this, ask the person or office requesting the document whether a notarized signature is actually required. Courts, attorneys and agencies sometimes accept other forms for people in custody. Only they can answer that, and a short call can save you a trip.

If it does need notarizing, a power of attorney is the most common jail document I see. It lets a family member handle bank accounts, bills or a car while the person is in custody.

Other jails near Chicago: MCC Chicago, Will County and DuPage County

MCC Chicago. The Metropolitan Correctional Center downtown is a federal jail run by the Bureau of Prisons, and federal rules apply. Start with the person's attorney, who usually knows how legal paperwork is handled there. Call me once the attorney has confirmed an outside notary visit is possible.

Will County Adult Detention Facility. The Will County jail is at 95 S. Chicago St. in Joliet. Call the facility first to ask how outside notaries and documents are handled.

DuPage County Jail. The DuPage County Sheriff runs the county jail in Wheaton. Same advice: confirm the facility's process before booking.

Suburban police lockups usually hold people only briefly. If someone is in a local lockup, it's often quicker to wait until they're transferred or released, unless the document truly can't wait.

How much does a jail notary cost?

Questions people ask

Can a notary go into Cook County Jail?

Sometimes, when the facility approves the visit. The jail sets its own rules for outside visitors and paper documents, and they change. Ask the jail or the person's attorney how a notary visit is approved before booking.

How do I find someone's booking number at Cook County Jail?

Use the Cook County Sheriff's online Individual in Custody Locator or call the jail's information line at 773-674-5245. You'll need the booking number for mail, visits and most paperwork.

Can I bring the document with me to the jail?

Don't assume so. In 2023 the Sheriff's office restricted visitors from bringing paper into the jail, and WBEZ reported paper had to be scheduled ahead so staff could inspect it. Confirm the current rule before the visit.

What ID does an inmate need to sign a notarized document?

Illinois requires government-issued photo ID with a signature that's valid at the time of signing, unless the notary personally knows the signer. The person's driver's license or state ID is often in their property from booking, so ask whether staff can make it available. A jail wristband usually isn't enough.

Can I mail a document to someone in Cook County Jail to sign?

Mail goes to the person's name and booking number at 2700 S. California Ave., Chicago, IL 60608, and it's inspected. But mailing it doesn't get it notarized; the person still has to sign in front of a notary.

How much does a jail notarization cost?

My jail visits start at $150: a $145 travel and service fee plus $5 for the first notarized signature. Each additional notarized signature is $5, and you get an itemized receipt.

Can you get my document notarized at MCC Chicago?

MCC Chicago is a federal facility with its own procedures. Start with the person's attorney, and call me if they confirm an outside notary visit can happen.
