Clicking I Agree: How an Online Agreement Is Formed

The points below about agreements concluded by clicking rather than signing are ordered by how much difference they make, not by how often they get repeated.

Assent without paper

The elements a legal system looks for in an agreement do not disappear because the transaction happened on a screen. There must still be something offered, something accepted and, in many systems, an exchange of value between the parties. Clicking a button can express acceptance perfectly well, since legal systems have never required any particular physical ritual.

The difficulties arise around what exactly was accepted, given that almost nobody reads the terms attached to the button. Courts have generally been unsympathetic to the argument that not reading a document prevents being bound by it.

When the terms were put in front of you

Whether terms form part of an agreement usually turns on whether they were reasonably available before the moment of acceptance. Terms presented after payment, or reachable only through an obscure link, are on weaker ground than terms shown in the flow. A design requiring a deliberate action, such as ticking an unticked box, produces a much clearer record of assent.

A design where terms sit behind a small footer link is more vulnerable to argument, though outcomes vary by jurisdiction. The distinction is about notice rather than about actual reading, which is why interface design has become a legal question.

Particularly onerous terms

Several systems require unusual or burdensome clauses to be highlighted rather than merely included among the rest. The reasoning is that a person agreeing to standard terms expects standard content and is not on notice of surprises. Automatic renewal, restrictions on bringing claims and unusual charges are the sorts of provisions that attract this treatment.

How far the requirement goes, and what counts as sufficient prominence, differs between countries and is still developing. The safest reading is that presentation matters, not that any particular presentation guarantees a clause will hold.

Terms that change after you agreed

Most online services reserve the right to amend their terms, sometimes with notice and sometimes with none at all. A clause allowing one party to rewrite the bargain unilaterally sits awkwardly with the idea of agreement between two sides. Some systems restrict such clauses, especially in consumer contracts, and may require meaningful notice and a right to leave.

Continuing to use a service after notice of a change is commonly treated as acceptance, though not universally. Whether a specific change binds a specific user is a question about local consumer law rather than about the clause alone.

Records and proof

The party relying on an online agreement generally has to show what was displayed, when, and what the user did. Systems that log the version of terms shown and the moment of acceptance are far better placed in a dispute. Screenshots taken by a user at the time of purchase can be similarly valuable when terms are later amended.

Because interfaces change frequently, reconstructing what a page looked like months earlier is often impossible for either side. Evidence, not principle, decides most of these arguments, which is a pattern that repeats across contract disputes generally.

An area still in motion

Rules on electronic signatures, digital consent and cross-border online sales have changed rapidly and continue to change. Some transactions still require particular formalities that a click cannot satisfy, and land and succession documents are common examples.

For most everyday situations, which transactions those are is entirely a matter of local law and cannot be inferred from how other countries treat them. Businesses selling internationally often face several sets of rules at once, applying differently depending on where the buyer is. Anyone building or challenging an online contracting process should take advice in each jurisdiction that matters to them.

6. An area still in motion. Rules on electronic signatures, digital consent and cross-border online sales have changed rapidly and continue to change.

The takeaway

The button is the signature, and the layout around it is the argument. General information only; this is not legal advice.

Most disputes are settled by whoever kept the better record.
