The messy divorce of Kim Zolciak and Kroy Biermann: legal battles, finances, and restraining orders.

Kim Zolciak and Kroy Biermann's divorce may turn nasty as Biermann seeks sole legal and physical custody of their four children, while Zolciak asked for primary physical custody and joint legal custody in her petition. The couple is also reportedly in financial trouble, owing $1.1 million in unpaid taxes and their Georgia mansion going into foreclosure earlier this year. A legal expert says that the request for sole custody indicates a potentially nasty divorce, as it is rarely granted unless one parent is unwilling or unable to parent.
