Mustufa Rangwala
Add checkbox on template/page like contact us form and make it mandatory:
=========================================================
<div class="form-group form-field o_website_form_required_custom"> 
<input type="checkbox" id="opt_out" name="opt_out" t-attf-value="#{opt_out or ''}" required="required"/>  
</div>
=========================================================
Add script inside form tag (Before </form>).
<script type="text/javascript">
$(document).ready(function (e) { 
$('.o_website_form_send').click(function() {
if (!$("#opt_out").is(":checked")) { 
e.preventDefault(); 
});
}); 
</script>
