I'm going to assume that we're talking about a single checkbox (an "I agree to the terms" checkbox).
First, remember that unchecked is not the same as "blank", it is "false", so "blank=False" is subject to interpretation. There are two places where you might insist that the box be checked: in the browser; and in the form processing. You *must* provide at least the latter, since the first depends on JavaScript (since, as you've discovered, the required attribute of a checkbox input doesn't always work across browsers), which is disable-able and otherwise circumventable. The js approach is to disable the submit button on load (stays enabled if js is disabled or the page is otherwise broken) and attach an on change handler to the checkbox that enables or disables the submit button based on whether the checkbox is now checked or not. But the mandatory part is to add a validator to the field (see https://docs.djangoproject.com/en/1.4/ref/forms/validation/ ) that fails with a suitable error message if the checkbox field value is False.
