What is a common mistake made by notaries regarding signatures?

Overlooking necessary signatures from all parties is a common mistake made by notaries because it can lead to the invalidation of a document. In many legal transactions, especially those involving multiple parties, every required signature needs to be present for the document to be legally binding. If a notary fails to ensure that all necessary parties have signed the document, it can result in complications or disputes later on. This oversight can undermine the integrity of the notarization process and can hinder the enforceability of the agreement or contract being notarized. Notaries have a responsibility to be thorough in their review of documents to ensure compliance with legal requirements, which includes confirming that all appropriate signatures are obtained before proceeding with the notarization.
