Terms That Actually Bind: Online Contract Formation, Arbitration Clauses, and Why Courts Refuse to Enforce Your Terms of Service
By Casey Scott McKay ·
A company's terms of service are worth exactly as much as its ability to prove a particular user agreed to a particular version on a particular day, and most companies cannot. This article explains the formation doctrine courts actually apply - reasonably conspicuous notice plus an unambiguous manifestation of assent - and why that test turns on interface design rather than on drafting. It walks the spectrum from clickwrap through sign-in wrap to browsewrap, the specific design failures that sink each, and the modification problem that voids terms nobody was told had changed. It covers arbitration clauses and class waivers, the delegation question, and the mass-arbitration economics that have made a winning clause expensive. It closes with the evidentiary record a platform must build before it ever needs one, and the regulatory overlay that now polices the same screens.
