10:12 AM PT -- According to the police affidavit, obtained by TMZ, cops say Michael told them Jules punched and scratched him in the face ... all while Michael recorded the encounter on his phone. Cops say they reviewed Michael's footage and say it backs up his claims. Cops also said they noticed a reddish mark on his left cheek and a small scratch on his nose.
The incident went down Sunday morning in what was supposed to be a simple custody exchange. Michael was dropping off the kids with Jules. Cops say Michael told them he started recording Jules because he felt threatened from a previous argument over the phone about child support payments.
Then there's this ... cops say Michael told them when Jules got out of her car, she pulled a baseball bat from her backseat but immediately placed it on the floor. Cops say when they talked to Jules she admitted to pulling the bat and putting it down on the ground before approaching him, telling them "I was angry" and "I smacked him."
'Real Housewives of New York' star Jules Wainstein is in hot water down in Florida ... and we ain't talking hot tub.
According to docs, obtained by TMZ, Jules was busted Sunday in Boca Raton for domestic battery. It's unclear at the moment who the alleged victim is. Jules spent the night in jail and was released Monday under her own recognizance.
She's scheduled to return to court Tuesday. In docs, Jules was found indigent ... which means she can't afford a lawyer. A public defender will be assigned to her case.
Jules is no stranger to domestic disturbances. As we reported back in 2016, Jules called 911 after getting into an angry argument with her estranged hubby, Michael. Their divorce case was pretty nasty.
