Common error
Do not use "in unaltered form" when you specifically mean "in natural form". While something in its natural form is usually unaltered, the phrase "in unaltered form" implies a comparison to a previous state or a potential process of change that was avoided. For example, a processed document can be returned to you "in unaltered form", but it is certainly not in its natural form.
