Kim Kardashian's Lawyer: Kris Humphries' Lawyer is a Liar

Kris Humphries is threatening to destroy Kim Kardashian's reality TV career, unless he gets what he wants in their divorce case ... this according to legal docs obtained by TMZ.

Disso queen Laura Wasser complains in new docs ... Humphries' lawyer, Lee Hutton, was LYING when he told the judge he didn't tell her he was on a mission to "blow the lid off reality television"

What's more ... Wasser strongly insinuates Humphries and Hutton have been threatening to use the divorce case to "expose" Kim's show, unless they get money and/or an annulment.

As for Hutton's threat, Wasser says he bluntly told her, "The Kardashians or Bunim-Murray [producers of 'Keeping Up with the Kardashians'] do not want that to happen."

Wasser says Hutton has virtually ignored the divorce ... she says 95% of his deposition questions have been about the ins and outs of Kim's show. Among the questions Hutton asked producers:

• "Is any aspect of season 6 [which features Humphries] scripted? If so, who maintains those scripts?"
• "Are storyboards created for season 6?"
• "It's not uncommon for a producer ... to give direction to cast members during a particular scene, is it?"
• "Can you tell me who gave direction to the characters for the Bora Bora episode on what topics they should discuss? [The episode in which Kris finds out Kim had previously been married]."

Ouch.
