In the docs, obtained by TMZ, Chase attached a bunch of statements from her account to demonstrate she's been behind on payments dating back to Nov. 2022.
The balance, they allege, has only ballooned ... and now, they say they want their dough. Remember, Kroy also got sued by Chase Bank over another credit card account he had with them ... and in that instance, they alleged he owed quite a bit more -- about $13,000.
Speaking of KB, he got hit with a judgment in a completely separate case -- although, it pertains to the same sort of allegations. Discover is suing him over a balance it says he owed, which had grown to $11,275.45 ... and was past due.
Per new legal docs, Kroy never officially filed a response in that suit -- and now, a judge has signed off on a default judgment saying he's gotta fork over that full amount ... plus $111 of court costs.
