Laura Dern/Ben Harper Divorce Docs

10/12/2010 2:33 PM PDT
TMZ has obtained a copy of the divorce documents Ben Harper filed Friday, asking for a divorce from Laura Dern.

As we first reported, Ben claims he's been separated from Laura since January. Now we know the specific date -- Harper claims the date of separation is New Year's Day.

What's weird -- the couple has been living and traveling together all this year.

The significance of the date of separation is all about $$$.  When a couple is legally separated, their earnings become separate.  We're told Harper out-earns Dern by a lot.
