Other things to know
- Missouri law regulates notaries. We will not notarize documents that do not follow such laws and regulations. Notaries will not prepare or complete documents for you, nor can they give legal advice on a matter.
- Per Missouri law, notaries will not provide service if the document or circumstances of the request for notary service raise any question of authenticity, ambiguity, doubt, or uncertainty for the library. In this event, the notary may decline to provide notary service at their sole discretion.
