Mike Epps' estranged wife is asking him to fork over six-figures every month to support the fam ... according to new docs.

Mechelle Epps claims Mike makes $3.5 million a year, but recently cut her off from bank accounts and credit cards, leaving her high and dry with zero income. She says Mike never wanted her to work during their marriage, and now she can't land a job because she's too old at 36.

In the docs, Mechelle says she spends several thousand bucks a month on shoes and clothes for their 10 and 12-year-old girls. Plus, the girls have to get their hair braided at an "expensive salon" ... not to mention food, vacations and $72k per year for private schooling.

Mechelle says her mom handles nanny duties for a mere $3,500 monthly, plus another $600 to cover Mom's Mercedes.
