A lawyer for Kim Kardashian's estranged husband wants to end his involvement in the former couple's divorce proceedings.

Marshall Waller says irreconcilable differences have arisen between him and Kris Humphries, and he should be allowed to leave the case.

He filed paperwork Thursday, one day before he and Kardashian's attorney are expected to appear in court for a scheduling hearing.

Kardashian is asking a judge to schedule a trial as soon as possible, while Waller has been advocating for more time to prepare.

If Waller is allowed to leave, it could delay a judge's decision on a trial date.
