Kim Kardashian filed for divorce Monday morning, after 72 days of not-so-wedded bliss to Kris Humphries ... TMZ has learned, and now we have the documents.

We're told even though the marriage was short, she is not seeking an annulment. It's a garden variety divorce, in which Kim cites "irreconcilable differences."

The date of separation is listed as today, Oct. 31, 2011. According to the docs, Kim wants Kris to foot his own lawyers' fees and she'll pay hers. And, she wants the court to reject any move by Kris to get spousal support.

And, the docs list the length of the marriage as a measly 2 months.
