Master P's estranged wife claims he's worth $200 MILLION ... yet she says he's left her and their 4 minor kids so destitute ... she needs welfare.
Sonya Miller says she's indignant ... because she helped Master P create one of the most successful labels in hip-hop -- No Limit Records -- yet he has cut her off like a bad habit.
Sonya says things have become so desperate ... she had to move in with her adult son, Lil Romeo.
Master P hasn't even responded to her divorce petition. The judge fined him $10K for ignoring the case, but he doesn't seem to care.
Sonya explains in her docs she hooked up with Master P when he didn't have a pot to pee in ... back in '89. They started the label together, and when it exploded, they built an empire, which include clothing manufacturing, sports management, toy manufacturing, and film and TV production.
Oh yeah, they also created an adult erotic phone chatline.
She may be working the phone line if Master P doesn't ante up.
