How to Become a Notary in Missouri (2026)

Requirements to Become a Notary in Missouri

Becoming a notary public in Missouri requires meeting several key qualifications set by the state. Here is a detailed overview of what you need:

• Minimum age: 18 years old
• Residency: Must be a legal resident of Missouri
• Surety bond: Required — $10,000
• Education: No mandatory education requirement
• State exam: Not required

Missouri notaries serve an essential role in preventing fraud by verifying the identity of individuals signing important documents. Whether you plan to work as a mobile notary, a signing agent for loan documents, or simply add notary services to your current role, understanding these requirements is the critical first step.

Missouri Notary Application Process

The application process in Missouri involves submitting your application through the Missouri Secretary of State. Here is a step-by-step overview:

1. Verify you meet all eligibility requirements listed above.
2. Purchase a surety bond in the amount of $10,000 from an authorized surety company.
3. Submit your completed application and the filing fee of $25 to the Missouri Secretary of State.
4. Once approved, purchase your official notary stamp/seal and begin your commission.

Processing times vary, but most applicants receive their commission within 4 to 8 weeks of submitting a complete application.

Missouri Notary Fees

Missouri sets maximum fees that notaries may charge for their services. Here are the current fee guidelines:

Mobile notaries in Missouri often charge additional travel fees on top of the per-signature fee. These travel fees are negotiable and vary based on distance, time of day, and urgency. Many successful mobile notaries in Missouri earn between $75 and $200 per signing appointment.

Commission Length in Missouri

A notary public commission in Missouri is valid for 4 years. It is important to track your expiration date and begin the renewal process well in advance to avoid any lapse in your commission.

An expired commission means you cannot legally perform notarizations. Any notarial acts performed after your commission expires are invalid and could expose you to legal liability.

How to Renew Your Missouri Notary Commission

Submit renewal application and new bond to the Secretary of State before commission expires.

We recommend starting the renewal process at least 60 days before your commission expires. This ensures there is no gap in your ability to perform notarial services. If your commission lapses, you may need to go through the full application process again.

Common Mistakes to Avoid

New and experienced notaries alike can fall into common pitfalls. Here are the top mistakes Missouri notaries should watch out for:

• Not filing commission with county recorder
• Using expired seal
• Failing to properly identify signers
• Providing legal advice — notaries are NOT attorneys (unless separately licensed)
• Not understanding the difference between an acknowledgment and a jurat
