The ranking of schools is subjective, and anyway, you want a lawyer, not a pedigree. Graduation from a given law school simply does not insure that this lawyer can handle your legal matter. Any lawyer who claims never to have lost a case simply hasn't tried enough of them. This kind of statistic is meaningless unless you get deeply into the facts of each case. As a client, you don't have time to do this.
Most lawyers belong to many organizations with highfalutin names.
But nearly all the organizations that a lawyer belongs do will accept as members anyone who can pay the membership fee, so membership doesn't guarantee anything. Yet requiring a lawyer to be members of these invitational bodies doesn't solve the problem, either, because they usually require a greater amount of trial or appellate experience than most lawyers can get these days, and you may be shortchanging yourself. Many fine lawyers have never won an award because they've been too busy representing their clients and raising their families to devote the kind of networking necessary to win such awards. As a client, you don't have the time to investigate the backgrounds of the awards to determine if they really mean anything. Picking a qualified lawyer is among the hardest decisions the client has to make in a case.
