What is an Electronic Signature?

An electronic signature (eSignature) is a digital replacement for a handwritten (wet) signature and is just as legally binding.

Traditionally, a signature is used to affix the unique identification mark of an individual to a document as undeniable evidence that they have personally witnessed and certified some or all of the contents of the document.

UK law uses a “technology-neutral” approach, allowing the law to adapt and evolve in line with technology. The same technology-neutral approach is also taken by the EU's Advanced Electronic Signature Standard and US law.

Because the law lays down the criteria for creating a contract, not the technology that must be used, an eSignature is legally binding, just like the wet signatures they are replacing.

Did you know? In the 16th Century, to prove document and contract authenticity, the two parties involved would tear the paper in half. Then, upon a dispute, the perfect fit of a document's halves would prove its authenticity.

In the modern world at Legalesign, we perform this document authenticity by PDF Certification.

Electronic signatures are fast becoming the gold standard for business.

In the age of technology, why not take advantage of it? eSignatures offer a quick, convenient and secure alternative to wet signatures.

With Legalesign, when you send your documents out to be signed, you'll know you're connecting with the right person and retaining complete control of the signing event via single-use links.

Advanced Electronic Signatures With Legalesign

Advanced Electronic Signatures with our software give the issuer and signatory absolute confidence in the authenticity of both the document and signature.

Created as a part of the EU's eIDAS Regulation, an Advanced Electronic Signature must be uniquely linked to the signatory, capable of identifying the signatory, be created using electronic signature creation data that the signatory can, with a high level of confidence, use under his/her sole control and be linked to the data signed therewith in such a way that any subsequent change in the data is detectable.

Legalesign is an electronic signature portal for business that takes care of Advanced Electronic Signature requirements behind the scenes, leaving you with an eSignature tool you can use with absolute confidence in any scenario.
