Kris Humphries
 has filed legal documents in his divorce case appointing himself as his own lawyer … TMZ has learned.

Kris — who makes $8 mil a year with the New Jersey Nets — wanted his Minnesota business lawyer to rep him in the Kim Kardashian divorce. But in California, an out-of-state lawyer must have a local attorney by his side. So Kris hired a Los Angeles lawyer.

But we found out the L.A. lawyer has withdrawn from the case, so the Minnesota lawyer doesn’t have a sponsor anymore. Translation: Mr. Minnesota is persona non grata in court.
