Kardashian cited "irreconcilable differences" as the reason for the split and requested Humphries pay his own lawyers' fees for the divorce proceedings, TMZ said.
She also requested Humphries be denied spousal support.
The couple got engaged last May after about six months of dating, and tied the knot in August. A special called "Kim's Fairytale Wedding: A Kardashian Event" aired on E! this month.
