Law is not an area where you must see specific credentials to feel comfortable with a practitioner. The law degree and license speak volumes about someone having achieved the minimum standards for competency.

Still, there are some legal specialties, such as a "certified tax lawyer" or "certified civil trial lawyer." While there are major trade groups like the American Trial Lawyers Association that have developed credentials, most national specialty law groups are membership organizations, rather than education/credentialing institutions.

Thus, you may need to distinguish between whether the lawyer is a member or a certificant.
