What is an Electronic Signature or eSignature?

The Electronic Signature & Records Association (“ESRA”) defines an electronic signature as:

“an electronic sound, symbol or process that is attached to or logically associated with a record and executed or adopted by a person with the intent to sign the record.”

In layman’s terms, an electronic signature is a string of virtual fingerprints that are used to verify the identity of a signer and validate their intent to sign the document.

Why should I use an online electronic signature tool?

We are all familiar with the old-fashioned way of requesting client signatures: Print. Sign. Scan. Repeat. After all of the hard work preparing the required forms, this seemingly simple process can lead to agonizing delays.

With Mango’s eSignature services, you can get documents signed electronically by your clients at anytime and from anywhere.  You just upload the document and it is delivered to your client to sign instantly.


Are electronic signatures legally binding?

The Uniform Electronic Transactions Act (“UETA”) and the Electronic Signature in Global and National Commerce Act (“ESIGN”) provide legal guidelines for ensuring the validity of electronic records and signed documents online.


Together, these pieces of legislation allow eSignatures to be recognized as legally binding if the following requirements are met:

  1. The signer’s identity can be confirmed or authenticated using a digital marker, like an IP address.
  2. The parameters of the transaction are communicated and the signer undeniably intended to undergo the method of signing.
  3. The signature associated with the document is verifiable and has evidentiary documentation.


Mango provides a digital audit trail that compiles the following unique identifying information so you can validate the identity of a signer and prevent tampering:

  • IP addresses
  • OS and browser information
  • Geographic coordinates
  • Time and date stamps

eSignatures FAQ's

Digital signatures work by leveraging an encrypted system that is based on a standard technological framework called the Public Key Infrastructure (PKI).

Many eSignature services provide static KBA methods that allow users to select security questions (like “What street did you grow up on?”) and provide answers that are stored by a company and accessed later, usually when a password needs to be retrieved or reset.

Dynamic KBA goes a step further by generating questions that apply only to the intended end user and do not require a previous relationship with the customer. These types of questions have also been called “out-of-wallet” as the content is generated from information within a person’s credit history or public records.

When it comes to electronic signature management, dynamic KBA is the preferred electronic signature option because of its increased security.

With electronic signature software, the questions are generated from the user's credit history or public records. Many regulatory bodies, including the IRS, require that eSignature users be authenticated using dynamic KBA. The best eSignature software will provide you with dynamic KBA authentication options (for example, with questions like "Which of these addresses do not represent somewhere you've lived?").

To qualify as an enforceable electronic signature, there must be evidence of the signer's intent to execute or accept the agreement. With business eSignature software, digital signature services typically accomplish this by requiring the signer to take affirmative action, like typing their name or drawing a digital signature using a mouse or touchscreen.

An electronic signature is a digital form of a wet ink signature that is legally binding and secure. A digital signature is a secured signature that works with eSignature technology and relies on Public key infrastructure.

Today, electronic notarization of electronic signatures is legally authorized in all states by E-SIGN and/or UETA. However, as of October 2020, only 29 states had laws that empowered their notaries to conduct remote notarizations.

The states that have implemented Remote Online Notarization (“RON”) statutes are Alaska, Arizona, Colorado, Florida, Hawaii, Idaho, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio, Oklahoma, Pennsylvania, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, and Wisconsin.

To qualify as an enforceable electronic signature, there must be evidence of the signer's intent to execute or accept the agreement. This is typically accomplished by requiring the signer to take affirmative action, such as ticking a box, typing their name, or drawing their signature.
