'Welcome to Plathville' Season Premiere: See Inside Kim's Surprising New Home Amid Separation (Exclusive)

As Kim put it on 'Welcome to Plathville,' "It's sort of a less expensive way of having waterfront property."

Still, it's an adjustment for her youngest daughters, Cassia, Amber, and Mercy, as they maneuver around the tight living quarters -- including two beds doubling as couches -- and take turns with a tiny bathroom. In the divorce filing, obtained by ET, Kim is seeking primary custody of their three minor children with a request that Barry pay child support. Added Kim and Barry, "We have been through many highs and lows in our 24 years of marriage and as we navigate this new chapter in our lives, we will co-parent our amazing children."
