Kim Zolciak has filed court documents accusing estranged husband Kroy Biermann of child neglect and physical abuse during their ongoing divorce proceedings.These allegations claim that Biermann subjected children to verbal tirades and inappropriate environments while maintaining primary custody of their four minor children.While Biermann previously secured decision-making authority after accusing Zolciak of parental misconduct, the court is now reviewing these fresh claims regarding the children's welfare.
