If you didn't want to create your own custom validator and still wanted to use existing attributes in the model you could use:

[Range(typeof(bool), "true", "true", ErrorMessage="You must accept the terms and conditions.")]

This ensures that the range of the boolean value is between true and true. However, whilst this method will work, I would still prefer to use a custom validator in this scenario. I just thought i'd mention this as an alternative option.
