A notary is a certified witness who validates signatures on official documents. Notaries must obtain licensing and become certified in the state where they are employed. A notary can authenticate the signing of contracts between individuals and the government, or between two individuals.
Notary services are necessary during the home buying and selling process. A notary signing agent is always present during the transfer of real estate to verify signatures on various documents. For example, a notary would verify the signatures on a deed.
