Is a term stating the contract can only be changed in writing, valid?
<p>For example <a href="https://www.lawinsider.com/clause/no-modification" rel="nofollow noreferrer">https://www.lawinsider.com/clause/no-modification</a></p>

<blockquote>
  <p>No Modification. This Agreement may be changed only by a writing
  signed by both parties.</p>
</blockquote>

<p>I know a contract is still binding without a signature, and even if it's not in writing. So are these types of terms enforceable? </p>

<h2>Absolutely</h2>

<p>Clauses requiring variations to be in writing are common and enforceable.</p>

<p>Of course, the parties can agree verbally to vary that clause - but if they agree it was varied, why are they in dispute?</p>

<p>It varies by jurisdiction. In Colorado, such terms are completely invalid. Some jurisdictions honor them.</p>
