In a recent blog post, we wrote about how the Second Circuit found the arbitration clause in a web service’s terms and conditions unenforceable because the user did not have reasonable notice of the terms that were communicated via a hyperlink in a post-sale email. In contrast, a New York district court recently upheld an arbitration clause in Coinbase’s account registration process and granted its motion to compel arbitration concerning claims brought by a user (Sultan v. Coinbase, Inc., No. 18-934 (E.D.N.Y. Jan. 24, 2019)).

This case sheds further light on the do’s and don’ts of online electronic contracting and the enforceability of app-based terms and conditions. The decision reinforces the point that for purposes of establishing a binding agreement with a user – particularly in the context of a mobile app – simplicity and clarity of the user interface is desired. And, in particular, this case reinforces the point that has been illustrated in many cases before that the design of user registration pages should be done with the input of legal analysis as to likely enforceability.
