Frequently Asked Questions

A digital signature is an electronic version of a traditional handwritten signature. It’s used to authenticate the sender’s identity of a message or document and ensure that the contents of the message or document have not been tampered with.

Individual users can sign documents electronically using various methods, including typing their name, drawing their signature, or using a fingerprint or other biometric.

Businesses also use digital signatures, often in conjunction with traditional handwritten signatures. For example, a bank may require both a customer’s handwritten signature and a digital signature on a loan agreement.

This process helps to ensure that the agreement is binding and that the customer cannot later claim that they did not sign it. Digital signatures are also used in various other contexts, from signing contracts to filing tax forms.

A digital signature offers a convenient and secure way to authenticate identity and protect against tampering with documents. Users can use mobile apps and platforms like Fill to create a digital signature.

Fill lets users sign documents on smartphones, tablets, and computers. Its intuitive features allow users to sign documents in a few seconds.

Yes, you can sign documents online.

With electronic signatures, you can add your signature to an electronic document just as you would add your signature to a paper document. That signature is then binding, just as if you had signed the paper document.

How does it work? When you electronically sign a document, you create an encrypted digital signature. Most premium electronic signature services use strong encryption to protect your signed documents and legally comply.

What makes it legally binding? Electronic signatures have the same legal weight as traditional signatures on paper documents. If you sign a contract electronically, you are legally bound by that contract just as if you had signed it on paper.

There are many benefits to signing documents online. It is convenient and allows you to sign documents from anywhere, and it is also fast and easy to do.

However, it is crucial to ensure that you are using a reputable digital signature app and that the person receiving the document is also using reputable software.

The legal status of digital signatures has been the subject of much debate, but there is now a general consensus that they are binding and enforceable in court. This is because digital signatures satisfy all the requirements of a valid signature under common laws.

In the United States, a digital signature is legally binding as long as it meets the requirements of the Uniform Electronic Transactions Act (UETA) and the federal Electronic Signatures in Global and National Commerce Act (ESIGN). The United Kingdom has supported electronic signatures since 2000 with the Electronic Comms Act and the E-Sign Act.

For a digital signature to be valid under UETA, it must be attached to or logically associated with the electronic record it intends to sign. It must be used by the person who signed the document to indicate their approval of the contents. The digital signature must also be unique to the person signing the document, meaning that it cannot be reused by anyone else.

Under ESIGN, a digital signature has the same legal force as a handwritten signature if it is affixed to or logically associated with an electronic record and used by a person with the intent to sign the document.

To be legally binding, a digital signature must contain the four elements:

1. The signer must have the intent to sign the document.

2. The signer must have the ability to control the electronic signature technology used.

3. The electronic signature must be attached to or logically associated with the document.

4. There must be a way to verify that the signature is authentic and has not been tampered with.
