Oksana Grigorieva In Bankruptcy Court -- Expenses Challenged ... Gopher Patrol?

Oksana Grigorieva isn't getting her massive debts excused that easily ... the person overseeing her bankruptcy case is scoffing at her expenses ... especially items like $90 a month for gopher patrol.

Oksana is asking the bankruptcy judge to cut her a massive break with a $438,000 hole she dug for herself with various creditors.

Her justification for getting a pass -- she has lots of necessary monthly expenses.

But the bankruptcy trustee begs to differ, saying some of the items are downright frivolous, including:

-- $2,000 a month in home maintenance
-- $750 in electricity and heating
-- $300 cell phone
-- $300 personal care
-- $90 a month for gopher patrol

And the trustee notes something suspicious ... just before filing for bankruptcy, Oksana ran up her credit card bill from zero to more than $51,000.
