Our licensed professional notary public services are here to make life easier. Once your documents are notarized, we will help you make any necessary copies and send them where they need to go.

Why do documents need to be notarized? A notary public acts as an impartial third-party witness to not only the signature of a document, but also that all parties who signed a document did so willingly and under their own free will.

Types of documents that may require notarization:
  • Wills
  • Trusts
  • Deeds
  • Contracts
  • Affidavits

Bring a valid, government issued photo ID with you when you visit De Soto Public Library for notary services.
