We’ve all heard of someone who hit the Enter key too quickly and sent an email he later regretted sending. Unfortunately, in some cases, the result is that the correspondents are deemed to have entered into a contract, without a formal writing and even in the face of evidence that the parties intended to later sign a formal contract. That was the case a few years ago when counsel for Amazon.com sent a one-word reply (“Correct”) to an email from opposing counsel outlining several specific terms of a settlement of a lawsuit. A Pennsylvania court faced a similar case in 2006, when it enforced an unsigned settlement agreement between Commerce Bank and First Union National Bank after concluding that the signing of the agreement was a mere formality since the parties had already evidenced their intent to be bound.
