Have an Illinois document that needs to be used internationally? We handle the apostille process from start to finish, including document review, submission preparation, notarization if required, Secretary of State processing, and return coordination, so your documents are handled correctly and efficiently.
If your documents are intended for use outside the United States, they may require an apostille or authentication before they will be accepted internationally. This process is technical, time-sensitive, and highly specific to the document type, issuing authority, and destination country.
Onyx Notary & Apostille provides professionally managed apostille and document legalization services, guiding clients through the process accurately and efficiently from start to finish.
What is an Apostille?
An apostille is an official certificate issued by a Secretary of State or federal authority that verifies the authenticity of a document for use in another country that is a member of the Hague Apostille Convention.
If the destination country is not a Hague member, the document will require authentication and legalization, which may involve additional state, federal, and consular processing.
We handle state apostille requests in all 50 states, federal document authentication through the U.S. Department of State, and document legalization support for non-Hague countries. If you are unsure which path applies to your documents, we help determine that before anything is submitted. We review the document type, issuing authority, and destination country before submission so we can identify the appropriate process for you.
Documents Commonly Requiring Apostille or Authentication
We regularly assist with apostille and authentication for personal, academic, legal, and corporate documents, including:
• Birth, marriage, and death certificates
• Powers of attorney and affidavits
• Sworn statements and notarized declarations
• Educational records, diplomas, and transcripts
• FBI background checks
• Court filings and legal documents
• Corporate records and business documents
• Estate planning paperwork
If your document isn’t listed, we’ll review it and confirm the correct process.
Certified Translation Services
Some documents must be translated before they can be accepted by a foreign authority.
Onyx Notary & Apostille offers certified translation services commonly required for international use, including translations of vital records, educational documents, legal paperwork, and official reports. Certified translations are arranged and managed to meet the standards and acceptance requirements of the receiving authority.
Translation needs are confirmed during the intake review to avoid delays or rejections.
Need certified translation without apostille service?
If you only need certified translation, you may complete our translation request form here. If your documents will also require apostille or legalization for international use, please use the apostille intake form so translation and document processing can be coordinated correctly from the start.
Our Process
Apostille and legalization work requires accuracy at every step. Our process is intentionally structured to eliminate guesswork.
1. Intake & Review
You’ll complete a short intake form and submit your documents for review. We confirm notarization requirements, issuing authority rules, translation needs, and destination country requirements.
2. Preparation & Submission
We prepare the required submission and personally coordinate delivery to the appropriate Illinois competent authority. If a document requires notarization, certification, translation, or another step before it is eligible for apostille, we help to identify that before submission.
3. Tracking & Communication
We monitor the process and provide clear updates so you always know the status of your documents.
4. Completion & Return
Once finalized, documents are returned securely by your preferred method or prepared for next-step use, including courier delivery when applicable.
