The first Martindale books were published in 1868, the principal one being Martindale’s United States Law Directory and later Martindale’s American Law Directory.

In 1930, the publishing rights to Hubbell’s Legal Directory were purchased by the Martindale Company and ever since have been known as the Martindale-Hubbell Law Directory.


A combination of a Legal Ability Ratings and General Ethical Standards Rating determines the Peer Review Rating. Unless a rating is established in both categories, no rating will be published.

Legal Ability Ratings: Rated on a scale of 1 to 5 (with 5 being the highest).

AV Preeminent (4.5-5.0) – Highest level of professional excellence rating

BV Distinguished (3.0-4.4) – Excellence rating

Rated (1.0-2.0) – Lowest level of professional rating

General Ethical Standards Rating is: “V” (Very High)


Generally, a law firm will be accorded the rating of its highest-rated principal.

In some instances, lawyers may be asked to submit names of lawyers and judges with whom they have had professional involvement. Inquiries are then directed to those sources in addition to sources developed by Martindale-Hubbell.

Field Representatives of Martindale-Hubbell visit tens of thousands of law offices on an annual basis. They make oral rating inquiries during these calls and submit written reports. However, a written review must occur before any rating is established, advanced, lowered, or withdrawn.


Based on the standard of ability for the area where the lawyer practices, it takes into consideration experience, nature of practice and qualifications relevant to the profession. Where a lawyer’s practice is limited or specialized, rating opinions are made on the basis of performance in those Fields of Law.


Embraces faithful adherence to professional standards of conduct and ethics of the legal profession, professional reliability and diligence, and standards relevant to attorney’s discharge of his or her professional responsibilities.
