Kris Humphries Wants Kim Kardashian to Fess Up ... How Much $$$ Did We Make?

Kris Humphries has filed legal docs ... asking a judge to reinforce the obvious -- that Kim Kardashian has a duty to disclose how much money the couple raked in during their 72-day marriage. But Kris is also challenging Kim's right to give away money that represents what they made in wedding gifts.

Kris' lawyer wants the court to reinforce that Kim has a duty to deal with him fairly and in good faith ... and that includes giving him a full accounting of the assets and liabilities accumulated during the marriage.

In the docs, Kris' lawyer writes, "A spouse may not make a gift of community personal property, or dispose of community personal property for less than fair and reasonable value, without the written consent of the other spouse."

It appears the lawyer is referring to Kim keeping the wedding gifts but giving double the value to charity.
