Are Digital Signatures Legally Valid?

Most countries accept digital or electronic signatures, provided you follow specific conditions. Always check your local laws to ensure your esignature is accepted as valid.

If you are in the United States, take a closer look at the E-Sign Act, also known as the Electronic Signatures in Global and National Commerce Act. This federal law was enacted in 2000. It establishes the legal validity of electronic signatures and records, making them as enforceable as paper documents with handwritten signatures.

Digital Signatures: The Best Option for Online Transactions

Here are some of the reasons digital signatures are the preferred option for signing PDFs and other documents.

  • First, they’re more secure than traditional signatures. A digital signature is like a fingerprint — it’s unique to the person signing the document. Thanks to encryption, it’s difficult to forge an electronic signature.
  • Using digital signatures is more convenient than traditional signatures. You don’t have to be in the same place as the person you’re signing a document with. With the right esignature, you can even sign forms online.
  • Finally, digital signatures are legally binding in most countries. So if you’re signing a contract or agreement, you can rest assured that it will be upheld in court.

Switch to digital signatures today and enjoy the convenience and security they offer. View, edit, and insert esignatures online without printing anything on paper.
