An apostille is an international certificate that verifies the authenticity of your Illinois notary's signature and seal. It allows your Power of Attorney to be recognized in any of the 120+ Hague Convention member countries without additional certification.
Your Illinois Power of Attorney must meet ALL of these requirements:
Multiple signers: Each signature needs its own notary certificate.
RON (Remote Online Notarization): Illinois accepts RON since 2022. Electronic notarizations are apostillable.
Name changes: Attach supporting documents (marriage certificate, court order) if requested by the foreign office.
Have an Illinois Notary Public notarize your Power of Attorney with a complete acknowledgment certificate. Ensure the notary includes their commission number, expiration date, and a clear seal impression.
Download the Illinois Secretary of State apostille request form. Include your contact information and the destination country (this is required for the apostille wording).
Include a check or money order for $2 per apostille, made payable to 'Secretary of State'. Cash is accepted for walk-in only.
Mail: Illinois Secretary of State, Index Department, 111 E. Monroe St., Springfield, IL 62756. Include a prepaid return envelope with tracking. Walk-in: Same address, Monday-Friday 8:00 AM - 4:30 PM (excluding holidays).
The Illinois Secretary of State will attach the apostille certificate to your notarized POA and return it via your chosen method. Processing takes 5-10 business days by mail, same-day for walk-in.

Problem: Wrong state: Sending Illinois POA to U.S. Department of State instead of Illinois SOS
Solution: Illinois-notarized documents must be apostilled by Illinois Secretary of State, not federal DoS.
Problem: Incomplete notary certificate: Missing commission number, expiration date, or seal
Solution: Return to the notary and have them complete the certificate properly or issue a new acknowledgment.
Problem: Non-Illinois notary: POA notarized by an out-of-state notary
Solution: Illinois SOS can only apostille documents notarized by Illinois notaries. Re-execute with IL notary.
Problem: Submitting photocopies: Sending a plain photocopy instead of original
Solution: Submit the original notarized POA. If you need to keep the original, have a notary create a certified copy.
Problem: Missing destination country: Not specifying which country the POA is for
Solution: Always include the destination country on your apostille request form.
