Walmart Heiress' Hubby Wants $400K

The man who's getting divorced from Walmart heiress Paige Laurie says he's become accustomed to their lifestyle and needs around a quarter of a million bucks a month to keep the yacht afloat.

Patrick Dubbert -- who separated from Paige after less than 6 years of marriage -- says in legal docs obtained by TMZ, he misses his life and she needs to fork over between $210K and $240K a month.

 AFTER TAXES (gross would be just over $400K a month) for necessities that include:

-  Rental home -- between $40K and 60K a month
-  Furniture -- $10K a month
-  Personal chef -- $6,700 a month
-  Clothes -- 5K a month
-  Personal trainer -- $2,500 a month
-  Vacations $30K a month (but that includes NetJets)
-  Entertainment $80K a month
-  Personal stylist -- $1K a month
-  Driver -- $4K a month

Dubbert complains he was living with Paige in their $11 million home, and now he's stuck in a Santa Monica apartment half of the year. He spends the other 6 months with his parents in Jefferson City, MO.

Dubbert's argument -- he's worked for her company, and he needs some time to get back into the job market -- and money -- to get back on his feet.

And he says, the law is the law and he's become accustomed to their lavish lifestyle, which included yacht parties that costs $500K a pop, travel in the Walmart private jet, and on and on.

He says Paige rakes in $872K a month just from stocks and dividends, so she can more than afford to pay him.

Here's the hardest one to swallow. He wants HER to pay him $2,500 so he can make charitable donations.
