Under the United States Electronic Signatures in Global and National Commerce Act (ESIGN Act) and the Uniform Electronic Transactions Act (UETA), electronic signatures, including a click-to-accept agreement, are legally binding and enforceable. These laws recognize that electronic signatures have the same legal standing as handwritten signatures and can serve as a valid method of demonstrating agreement to contract terms.
Additionally, the law recognizes that an "electronic sound, symbol, or process attached to or logically associated with a record and executed or adopted by a person with the intent to sign the record" can constitute an electronic signature. This means that a click-to-accept agreement, where a person clicks on a button indicating their acceptance of contract terms, is legally binding and can serve as an electronic signature.
It is important to note that a signature does not necessarily have to be a handwritten signature, and can instead take various forms, such as an electronic signature. Therefore, a click-to-accept agreement can be just as legally binding as a traditional signature on paper.
