Is an electronic signature legally binding if one of the parties is hosting the contract?
<p>When is an electronic signature (IP address, timestamp, and checkbox or PNG of the signature) on a contract legally binding? Can a contract be legally binding if it is hosted by one of the parties and said party can modify its contents at any time?</p>

<p><strong>Contracts do not have to be signed to be legally binding!</strong></p>

<p>They do not even have to be written down!</p>

<p>What is required (among other things) is that the parties demonstrate their intention to be bound by the contract. If one person offers a contract (in whatever form) and the other person consents to its terms (in whatever form) then they have a contract.</p>

<p>When it is done in such a way that it signifies a consent to be legally bound.</p>

</blockquote>

<p>Yes.</p>

<p>If the contract one party the power to modify it unilaterally then it can be modified unilaterally within the scope of that power and that contract (you would be an idiot to sign such a contract for anything significant). All contracts can be modified bilaterally by agreement.</p>

<p>If one party changes the contract when they do not have the agreement of the other or the power to do so unilaterally then that is fraud and does <strong>not</strong> change the terms of the contract.</p>
