Sources connected to all three men tell TMZ, they never papered their financial and custodial arrangements. We're told Travis Scott and Kylie don't have anything in writing regarding custody or support of their newborn daughter. Same goes for Tristan Thompson and Khloe Kardashian, although that may be a bit premature since she hasn't given birth.
More interesting, perhaps, is that we're told Scott Disick doesn't have a written custody agreement with Kourtney Kardashian.
