Notarisation is a process of verifying a document by a notary public or any other authorized individual. It helps to prove the authenticity of the document and its signatories. However, there are other synonyms that mean the same as notarised. These include validated, certified, attested, witnessed, verified, and endorsed. Each word may be used in the context of validating the authenticity of a document such as a contract, deed, or agreement. These words can be used interchangeably and are often used to add legal weight to the document. Whichever word is used, the main purpose is to ensure that the document is legally binding and that the signatories are who they claim to be.
