2:13 PM PT -- A rep for Antonio tells TMZ Sports ... "His mother has been paying the mortgage on the house since 2011. That's the deal they have in place."
"It wasn't until June that she refused to make any payments."
The rep says Antonio's children are his priority financially -- and he adamantly believes his mother and her husband have the funds to support themselves.
The mother of NFL star Antonio Cromartie claims her son is trying to evict her from the Florida home he bought for her back in 2007 ... and it's all over money.
TMZ Sports spoke with Cromartie's little sister, LaQuinta Gardner ... who says their mother was served with an eviction notice on Thursday and the family is pissed.
Gardner claims ... Cromartie bought the house and paid for everything for years -- but the gravy train stopped in February when he asked his mother to pay the $700 per month mortgage bill.
We're told the mother refused -- insisting Cro, who's made millions in his career, should pay since the house was supposed to be a gift.
Both sides dug in ... culminating in the eviction papers, which say Cro's mother needs to be out by August 15th ... UNLESS she forks over a check for $2,310 in back payment.
Gardner says she has set up a GoFundMe page to raise money for her mother.
We reached out to Cromartie for comment -- so far, no word back.
By the way, Cromartie is currently unemployed -- and has 12 kids ... and that ain't cheap!
