The New Jersey Supreme Court Committee on Attorney Advertising has restricted lawyers’ use of some modern marketing tools: catchy Web site addresses and testimonials from happy clients.

In two opinions published May 23, the committee says law firms are free to adopt Web addresses describing their practice specialties like “njtortlawyer.com” but may not identify themselves in ads with the Web address in lieu of the firm name, and law firms may not include in their advertising satisfied clients’ endorsements about the effectiveness of representation but may include endorsements limited to the quality of attorney-client interaction.
