Matthew Knowles will appear in court on Friday (13.12.13) amid allegation she is behind on child support payments for his four-year-old son Nixon.
The showbiz patriarch is reportedly two months behind in maintenance to Alexsandra Wright, the mother of his four-year-old son Nixon - who he has never met - and so their financial row will be heard in a Los Angeles courtroom later this week, RadarOnline.com reports.
Matthew - who used to manage Beyonce - was previously branded a "deadbeat dad" by Nixon's uncle after falling more than three months behind his reported $12,000-a-month payments.
Jonathan Wright, Alexsandra's brother, said: "I find it kind of odd that somebody that's proven as somebody's biological father has never ever seen their son.
"And when they're a wealthy individual, it's odd that they would be a deadbeat dad."
In 2009, Beyonce's mother Tina filed for divorce from Matthew after he reportedly had an affair with Alexsandra, who fell pregnant and requested a paternity test.
Beyonce, 32, and sister Solange, 27, didn't attend their father's wedding when he re-married earlier this year, tying the knot with former model Gena Charmaine Avery in Houston, Texas in June.
