Frequently Asked Questions

Questions Commonly Asked of a St. Louis Missouri Notary Public

Notary Meeting

Can a Missouri notary public notarize in the state of Illinois?

Unfortunately, no. 

With the State of Illinois just a short drive from downtown St. Louis, it would make sense that a Notary Public City of St. Louis could legally notarize for clients who are physically located in Illinois. However, it would be against the law for a Missouri Notary Public to notarize a document in the state of Illinois. According to the Illinois Secretary of State, “every applicant to be appointed and commissioned to perform notarial acts in Illinois must be a resident of Illinois or have full time employment in the State of Illinois.” So unfortunately, we are unable to help out our friends in Illinois.

Can a Missouri mobile notary notarize documents created in the state of Illinois, but are to be notarized in the state of Missouri?

Yes, as long as the notarial act is taking place in the State of Missouri, we can legally perform the notarization. 

Sometimes we get calls from concerned customers that the document that they need to be notarized was created in an Illinois County and that the notarial language on the document refers to both the Illinois County and The State of Illinois. That’s not a problem. It would be a simple two-step process. First, we would cross out the name of the Illinois County, initial the change and replace it with the name of the Missouri County where the actual notarization is taking place. Secondly, we would cross out Illinois, initial the change and replace it with Missouri. It is that simple. The same process can take place with every state and county in the United States as long as the notarization is taking place in the State of Missouri.

Our Notary Public stamp says St. Louis County on it, can we notarize in St. Louis City?

Yes. Let’s take a closer look at the language on a Clayton Mobile Notary’s notary stamp, because it contains several important pieces of information. 

At the top of the stamp it gives the notary’s full name as registered with the State of Missouri. The second line on the stamp lists the notary’s title, ‘Notary Public’, and identifies this stamp as being that individual notary’s Notary Seal. The third line lists ‘St. Louis County-State of Missouri’. 

If you are a resident of St. Louis County, you must be sworn in by the St. Louis County Clerk in order to be commissioned by the State of Missouri. If you move to another County in the State of Missouri, you would be required to be sworn in by the County clerk of your new residence. For example, if you move just a few miles away from the County to be a Notary Public City St. Louis, the Circuit Clerk with St. Louis City would swear you in. You would also be required to obtain a new notary stamp to reflect the new residency. But as a St. Louis County notary, you can notarize any document in St. Louis City or any county in the State of Missouri.
