Kristin Cavallari and Jay Cutler seemed to be moving along nicely with their divorce, but it's stalling ... and we're told it's because he wants a piece of her company.
Sources close to the ex-couple tell TMZ ... the reason it's taking a while to finalize their divorce is because Jay's seeking 50 percent ownership of Uncommon James, Kristin's chic jewelry and apparel line.
We're told Cutler's insisting he should get a stake in UJ because Kristin launched it while they were married ... and well before he filed for divorce in April, 2020.
