The fallen sports star, who once dated Madonna and was briefly married to model Carmen Electra, cannot keep up with payments to his third wife Michelle Rodman.
According to her attorney, Jack Kayajanian, Rodman owes her over $800,000 (£500,000) in child support and more than $51,000 (£32,000) in spousal support.
But Rodman's lawyer, Linnea Willis, maintains her client can barely cover his living expenses, and cannot afford to hand over almost $5,000 (£3,100)-a-month to his ex.
He can't even pay his legal fees - Willis has revealed she is working for free.
Rodman faces 20 days in jail for failure to pay spousal and child support.
