Kanye West DEPOSED In Kim Kardashian / Kris Humphries Divorce

Kanye West has officially been dragged into the longest, most ridiculous divorce case ever -- Kris Humphries made Kim's rapper/bf sit for a deposition ... TMZ has learned.

Kim's lawyer, disso-queen Laura Wasser, is in court right now, essentially asking the judge to make Kris either s**t or get off the pot. As Wasser put it, "She [Kim] is now handcuffed to Mr. Humphries."

Wasser mentioned Kris and his lawyers are now raising issues over the prenup he signed, which we know gives him squat.

Wasser also expressed frustration that Kris is dragging his feet -- he hasn't even deposed Kim yet. Wasser calls the whole thing a "fishing expedition."
