Rossdale and Stefani's divorce was finalized last month
, after 13 years of marriage. ET learned that Stefani likely wasn't too happy with the terms of the settlement, specifically with regard to the section regarding the family's house. According to documents obtained by ET, Stefani and Rossdale will split the profits made from the sale of their home in Beverly Hills, although Stefani made significant upgrades to the property, including an entire new wing and a guest house. Selling the house also means she will have to uproot their three children -- Kingston, 9, Zuma, 7, and Apollo, 2 -- whom the two share joint physical and legal custody of.
