A notary public is a partial witness with a special commission from a state or county government that allows him or her to acknowledge the official witnessing of another person's signature on a document having a signature on a contract notarized is important for a few reasons. One of the most important ones is that under the Federal Rules of Evidence, a notarized document is considered "self-authenticating." The same is true under the rules of evidence in effect in each state, although there are a few states that don't follow this norm. When a document is self-authenticating, the signers of the contract do not need to testify in court to verify the authenticity of their signatures. That saves a lot of time and money. Having a document notarized is "a huge strategic advantage" in litigation.
While the duties of public notaries might be simple to execute, they are extremely important. First, a notary cannot attest to witnessing a signature unless the signer signs the document in their presence. To ensure the parties signing the document are the real people who are supposed to do so, some states require signers to present identification to the notary. The notary must also ascertain whether people are signing the document voluntarily or under duress. This is especially crucial when a senior citizen or someone with limited English skills is signing a document. In some states, notaries are required to maintain a journal of the documents they notarize. The journal details the type of identification presented to the notary and a basic description of the document he or she notarized.
