Indeed, consumers and businesses are often quite surprised and, in some cases, worried when they learn that seemingly casual conversations, which contain relevant language, may be enough to create a legally binding contract or even a guarantee. If you know your customer is picky and only finds excuses not to pay, dig into your emails. They find one where they say how much they love their new product. Can you use this email as evidence in court? Of course. In a recently published notice, the Texas First District Court of Appeals opened a court of law and ruled that while an email was not signed by the sender, the name or email address in the “von” box is a symbol logically related to the email, thus meeting the UETA signature requirement.
