I also ran into this recently. The "trick" is to add a value to your 
checkbox view helper:

<f:form.checkbox property="legalAgreement" value="false"/>

And to annotate the following in your model:

/**
  * @var bool
  * @validate Boolean(is=true)
  */
protected $legalAgreement;


Kind regards,
Helmut
