Richard Williams, tennis champs, Serena and Venus Williams’ 75-year-old father has filed for divorce from his much younger wife in West Palm Beach, Florida.

In his petition, the 75-year-old tennis coach often credited for training his daughters in their younger years and laying the foundations that eventually made them into tennis superstars, believes his 38-year-old wife of seven years, Lakeisha Williams, is an alcoholic.

He also claims she is stealing his social security checks and transferred ownership of their cars and a house to herself by forging his signature.

Williams, who married Lakeisha in 2010, also claims she moved out last year and left their now 5-year-old son, Dylan, in his exclusive care.

Lakeisha is barely older than his two daughters – Serena is 35 and Venus will turn 37 on Saturday.

Richard Williams also alleges she left him for ‘a new person’ who has ‘serious criminal, felony charges pending who could impose a danger to the minor child,’ the document reads.

Sandy Becher, Lakeisha’s Miami lawyer, called Richard’s petition “outrageous.” 

“We categorically deny each and all the allegations he has made in the petition,’ Becher said. “When the issues come before the court, they’ll be proven to be patently false.”

DailyMail.com called Serena and a woman claiming to be  one of her assistants picked up her cell phone and promised to leave a message for Serena to comment.

Richard is currently overseas and didn’t return calls for comment and neither did his lawyer, Reginald Sessions.

The divorce petition, however, alleges plenty about his relationship with Lakeisha, and includes an unusually graphic litany of complaints against Lakeisha, a nurse’s assistant by trade.
