Law firms: Rule 7.1 of the North Carolina Rules of Professional Conduct
A lawyer may not make a false or misleading communication about the lawyer or the lawyer's services. The rule's own examples include statements likely to create an unjustified expectation about results and comparisons with other lawyers that cannot be factually substantiated. In practice, ad headlines like "#1 attorney" or "we win each case" are risky unless they can be substantiated.
