Notarization is the process by which a licensed notary public certifies the authenticity of signatures, documents, or transactions. It involves the notary verifying the identities of the parties involved, ensuring they sign voluntarily and with understanding. Notarization adds legal weight to documents, affirming their validity and deterring fraud. Commonly notarized documents include contracts, deeds, powers of attorney, and affidavits. By affixing their official seal and signature, the notary public confirms that the signatories are who they claim to be and that they acted without coercion. Notarization is crucial for ensuring legal integrity and enforceability in various legal and financial transactions.
