Occult Law Firm

"Founded in 1791 on ground deconsecrated by the blood of mass murderer Mathias Pavayne, Wolfram & Hart has put roots down in this glamorous city that grow deep, and branches that reach right into the heart of every major corporation, including Yoyodyne, Weyland Yutani and News Corp."

Comic Books

 * Goodman, Lieber, Kurtzberg & Holliway, the law firm that employed She Hulk for a time (although they represented aliens and underground civilizations, too).

Film

 * The Devils Advocate has Keanu Reeves as one for Satan (played by Al Pacino).
 * Winesap and MacIntosh, Louis Cypher's lawyers from Angel Heart.

Literature

 * The law offices of Moorecomb, Honeyplace, and Slant in Ankh-Morpork aren't necessarily 100% occult, but there's no denying they've been in the business longer than anyone else; Mr. Slant is a zombie (and a major player in city politics), and his partners (who never actually appear, but are obviously mentioned whenever the firm is mentioned by name) are both vampires. They don't necessarily specialize in supernatural cases, but then, nor do the firms run by living human lawyers specialize in mundane cases; that's just the kind of world Discworld is.

Live-Action TV

 * Wolfram & Hart from Angel, who start off as just a particularly evil-oriented example of this trope, and are later revealed to be the front organisation of an extremely powerful group of extra-dimensional demons who claim to be responsible for most of the evil on Earth.
 * Cole from Charmed originally posed as an Assistant District Attorney while he was plotting to kill the sisters and, after that collapsed, was employed by various law firms over the course of the series.
 * You were a lawyer and a demon? The jokes write themselves.

Web Comics
"Beware the Creatures of the Night — they have lawyers!"
 * Wolff and Byrd, Counselors of the Macabre, Supernatural Law.

Web Original

 * The law firm in Mack goes to in Tales of MU. Technically all law firms given the high fantasy setting, but this one is played as more willing than most to represent non-humans.
