Apostille Services
Apostille Authentication
for Missouri Documents
We help individuals and businesses authenticate U.S. documents for use in foreign countries — guiding you through every step.
What Is an Apostille?
An apostille is an internationally recognized certificate that verifies the authenticity of a public document for use abroad. If you need a U.S. document accepted in another country — for a marriage, adoption, employment, school enrollment, or business transaction — you likely need an apostille.
The apostille certifies documents for countries that are members of the 1961 Hague Convention. For non-member countries, embassy legalization may apply instead.
Documents Commonly Apostilled
- Birth, death, and marriage certificates
- Divorce decrees
- Educational transcripts and diplomas
- Criminal background checks (FBI & state)
- Powers of attorney
- Adoption documents
- Corporate documents and articles of incorporation
- Notarized affidavits and agreements
- Court documents and judgments
The Apostille Process — Step by Step
1
Identify Your Document Type
We help determine whether your document is state-level or federal — which determines whether the Missouri Secretary of State or the U.S. Department of State issues the apostille.
2
Prepare & Notarize If Required
Some documents must be notarized before receiving an apostille. We can handle notarization as part of the process.
3
Submit to the Correct Authority
Missouri state documents go to the Missouri Secretary of State. Federal documents require submission to the U.S. Department of State in Washington, D.C.
4
Receive Your Apostilled Document
Once the apostille is affixed, your document is ready for international use. We'll advise on any additional destination-specific requirements.
FBI Background Checks & Apostille
If you need an FBI background check apostilled — common for international adoption, immigration, or employment — we can help coordinate both the fingerprinting process and the apostille submission to the U.S. Department of State.
Frequently Asked Questions
How long does the apostille process take? +
The Missouri Secretary of State typically processes apostilles within 2–5 business days. Federal apostilles may take several weeks without expediting. We'll give you a realistic timeline based on your situation.
Do I need an original document or can I use a copy? +
In most cases, the apostille is attached to the original or a certified copy. Uncertified photocopies are generally not accepted. We'll advise you on your specific document.
What countries accept an apostille? +
Over 120 countries are members of the Hague Apostille Convention, including most of Europe, Mexico, many South American nations, and Australia. If your target country is not a member, we'll explain the legalization process instead.
Can you handle the entire process for me? +
Yes. We guide you through the full process — identifying requirements, notarizing documents when needed, and providing clear submission instructions. Contact us to discuss your situation.

Remote Online Notary (RON)
Notarize Documents
From Anywhere in the World
Get legally notarized documents via secure video session — no travel required. Available to clients worldwide, any day of the week.
What Is Remote Online Notarization?
Remote Online Notarization (RON) allows you to have documents notarized through a live, real-time audio-visual session over the internet. The notary and signer meet via secure video call, identity is verified electronically, and the document is signed and notarized digitally — fully legal under Missouri law.
Because Cornerstone Signatures holds a Missouri notary commission, RON sessions can be conducted with signers located virtually anywhere in the world. Whether you're a Missouri resident traveling abroad, a U.S. expat needing documents notarized, or an international client requiring a U.S.-commissioned notary, we can help.
How the RON Process Works
1
Book Your Appointment
Schedule your remote session online or by phone. We'll send a confirmation with everything you need and instructions for joining the secure video platform.
2
Identity Verification
Before the session, you'll complete a secure identity proofing process using knowledge-based authentication (KBA) questions and credential analysis of your government-issued photo ID.
3
Live Video Session
We connect via secure video platform in real time — from wherever you are in the world. The session is recorded and retained as required by Missouri law.
4
Electronic Signing & Notarization
You sign digitally, the notary applies an electronic signature and seal, and you receive your completed, legally notarized document instantly.
Who Can Use Our RON Service?
- Missouri residents anywhere in the world
- U.S. citizens living or traveling abroad
- International clients needing a U.S.-commissioned notary
- Military personnel and families stationed overseas
- Business professionals requiring notarized U.S. documents remotely
- Anyone who prefers the convenience of online notarization
What You Need for a RON Session
- A computer, tablet, or smartphone with a working camera and microphone
- A reliable internet connection
- A valid, unexpired government-issued photo ID
- Your document(s) in digital format
Documents Notarizable via RON
- Powers of attorney
- Affidavits and sworn statements
- Contracts and agreements
- Real estate documents (where accepted)
- Business and corporate documents
- Medical directives and healthcare documents
- Financial and banking documents
Important Considerations
While RON is legally valid and accepted by most institutions, some documents — such as wills or certain real estate recordings — may have specific requirements or may not be accepted remotely by all parties. We'll advise you upfront if any issues may arise for your document type.
If you have questions about whether a receiving party will accept a RON-notarized document, we recommend confirming with them before booking.
Wherever You Are, We Can Help.
