Kroy Biermann and Kim Zolciak are bickering over finances again ... and this time it's all about the money he thinks she's making from selling her designer gear.
According to new legal docs, obtained by TMZ, Kroy says his estranged wife's been selling off her expansive collection of designer purses, shoes and clothes ... but he says it's unclear what she's doing with the profits and whether any of the stuff being sold is marital property, as opposed to her separate stuff.
