Kim Zolciak Sued Over Credit Card Debt

Kim Zolciak has been sued yet again for not paying her bills ... this time by Bank of America, which claims she's delinquent on more than $50,000.

According to legal docs, obtained by TMZ, Kim had a $50,000 line of credit over at B of A, and then racked up a bill that reached the limit. B of A claims it sent periodic notices, demanding payment, but got zippo.

With interest and penalties, the balance is now $56,224.07 and growing. So B of A is now the latest in a long line of creditors who have resorted to the legal system to get Kim and Kroy to fork over cash.

BMW just won a case against Kroy over non-payment of a Rolls-Royce. A judge ordered this month that he return the $400,100 SUV to the car company.

Kim and Kroy have also been ordered to pay Simmons Bank approximately $230,000 for defaulting on a home equity line of credit.

Kim was sued back in August by SAKS/CAPITAL ONE for $156,080 ... again, failing to pay her credit card bill.
