Legality of digital signatures refers to the legal recognition and use of electronic, or digital, documents that are signed using digital signatures. Digital signatures protect the authenticity of the documents, ensuring that the document is legally binding and enforceable, just like a traditional hand-signed paper contract. They also provide a way for parties to prove the identity of signers and guarantee the precision and completeness of the document. In other words, digital signatures provide legal protection to both businesses and individuals who choose to use them.
