Master P: Battle Over Kids Getting Abusive ... Estranged Wife Claims

The war between Master P and his estranged wife Sonya Miller has reached a new level -- she's accusing him of verbal and physical abuse ... while plotting to turn their kids against her.

Miller was granted a temporary restraining order against P back in October, and a hearing is scheduled for Tuesday to make the order permanent.

According to court documents, Miller claims P has "brainwashed" their kids to go against her and used his money and power to wield influence over them. She also describes an incident from "long ago" where Master P allegedly hit her in the face and dragged her across the floor. She says she ended up in the hospital.

As of now, Master P must stay 100 yards away from Sonya. We'll see what happens in court on Tuesday. He responded to the allegations, telling us ... "I will pray for my ex. This is a sad day for our family, but we will get past this. After 5 years, all her attorneys can come up with are false accusations."
