Kim Kardashian and Kanye West can't get married, because their prenup is still being hashed out ... TMZ has learned.
Sources connected with Kim and Kanye tell TMZ ... the prenup won't be signed until next week -- probably Wednesday at the earliest. We're told the marriage will NOT take place until both sign on the dotted line.
Our sources say -- unlike Kim's prenup with Kris Humphries -- the current negotiations are friendly ... there's no fighting. We're told there's just a lot to work out, and it got complicated by the fact that Kanye recently changed management.
As for the wedding ... it's looking like Paris ... around Memorial Day.
