N.j. Ct. R. RPC 7.5
Official Comment to RPC 7.5(e) by Supreme Court (July 27, 2015)
By way of example, "Millburn Tax Law Associates, John Smith, Esq." would be permissible under the trade name provision of this rule, as would "Smith & Jones Millburn Personal Injury Lawyers," provided that the law firm's primary location is in Millburn and its primary practice area is tax law or personal injury law, respectively. "John Smith Criminal Defense and Municipal Law" would also be permissible. However, neither "Best Tax Lawyers" nor "Tax Fixers" would be permissible, the former being comparative and the latter being suggestive of the ability to achieve results. Similarly, "Budget Lawyer John Smith, Esq." is not permissible as it is comparative and likely to be misleading; "Million Dollar Personal Injury Lawyer John Smith, Esq." is not permissible as it suggests the ability to achieve results; and "Tough As Nails Lawyer John Smith, Esq." is not permissible as it purports to describe the lawyer and does not describe the nature of the firm's legal practice.
