Illinois Secretary of State Apostille

Apostille vs. Notarization — They're Not the Same Thing

A notarization verifies a signer's identity and witnesses their signature on a document. An apostille is a separate authentication certificate that verifies the notary's own signature and seal are legitimate, so the document can be recognized in a foreign country.

For a notarized document, the notarization comes before the apostille request, but having a document notarized doesn't automatically make it valid abroad. Foreign governments and institutions need the apostille as proof that the notary who signed was actually commissioned by the State of Illinois.

Who Issues Apostilles in Illinois

The Secretary of State Index Department in Springfield is the sole issuing authority. Since July 1, 2022, county clerks no longer issue Certificates of Authority to verify notary signatures — that function moved entirely to the state level.

This is a common point of confusion. Before 2022, notaries or their clients would take documents to the county clerk's office for authentication. That path is closed. Everything routes through the Secretary of State now.

When You Need One

An apostille is required when a notarized document needs to be used in a country that's party to the Hague Apostille Convention. Common scenarios include:

• Real estate transactions in another country
• Adoption proceedings with foreign courts
• Business formation documents for international ventures
• Academic transcripts headed to foreign universities
• Powers of attorney for overseas family matters

If the destination country isn't part of the Hague Convention, you may need a full embassy or consular legalization instead, which is a longer process.

The Process

The general sequence for obtaining an Illinois apostille:

1. Have your document notarized by a commissioned Illinois notary public
2. Submit the notarized document to the Secretary of State Index Department
3. The Index Department verifies the notary's commission status and signature against their records
4. If everything checks out, they attach the apostille certificate to the document

Submit the notarized document to the Secretary of State Index Department using its current apostille instructions.

What Notaries Need to Know

As a notary, you don't issue apostilles. Your role ends at the notarization. But understanding the apostille process matters because clients regularly ask about it, and giving wrong information about who issues them or how long they take creates problems.

The key boundaries:

• Direct clients to the Secretary of State Index Department for apostilles
• Never represent yourself as able to issue or expedite apostilles
• Ensure your notarization is properly completed before the client submits for authentication
