What to know about the Hall & Oates legal fight, and the business at stake behind all that music

After more than a half-century of making music together, Daryl Hall is suing John Oates over a proposed sale of his share of a Hall & Oates business partnership that Hall says he hasn’t approved

NASHVILLE, Tenn. — After more than a half-century of making music together, Daryl Hall is suing John Oates and arguing in arbitration that he can't sell his share of a Hall & Oates business partnership without Hall's permission.

Public court filings have revealed just how wide the rift has grown between the duo famous for hits in the 1970s and ’80s, including “Maneater,” “Rich Girl” “Kiss on My List” and “I Can’t Go for That (No Can Do).”

Hall has accused Oates of blindsiding and betraying him, saying their relationship and his trust in Oates have deteriorated. Oates has said he is «deeply hurt» that Hall is making “inflammatory, outlandish, and inaccurate statements” about him.

A Nashville judge recently paused the sale of Oates' stake in Whole Oats Enterprises LLP to Primary Wave IP Investment Management LLC until an arbitrator weighs in, or until Feb. 17.

Here are some recent developments.

The dispute went public on Nov. 16, when Hall filed a lawsuit in a Nashville chancery court asking a judge to stop the sale by Oates so a separate, private arbitration could begin. Hall's lawsuit contends that going to court was the only way to ensure the sale by Oates and others involved in his trust didn't close before an arbitrator could weigh in. Hall filed for arbitration on Nov. 9.

Still, the pair's private business holdings and their agreements are largely blocked from public view, even after a judge unsealed many filings. Oates' attorneys have argued that he lived up to his contractual obligations and didn't go behind Hall's back.
