"Saved the best for last... happy (late) Father's Day to Jay," Cavallari wrote in the caption of a throwback photo of the kids. "We had a beautiful day yesterday at my new house," Cavallari continued. "Modern family? Co-parenting? Whatever you want to call it, we are navigating it the best way we know how." In May, a source confirmed to PEOPLE that the former couple had reached a custody agreement after filing for divorce. Cavallari and Cutler agreed to be named "joint primary residential parents," each spending 182.5 days with the kids a year and alternating time on a week-on, week-off basis, according to court documents obtained by PEOPLE. They will alternate Easter and Thanksgiving, as well as fall and spring breaks, and will split the Christmas holiday. The agreement also notes that each parent will have the right to two phone calls and two FaceTime or Skype calls per week while the children are with the other parent.

"Right now, Kristin and Jay are 'bird-nesting' in terms of custody, where the kids stay put in one home and the parents rotate in and out," the source explained at the time. "This new main property would be perfect as a 'nest' for the kids and when it's Jay's turn to be with [them] in the main house, Kristin would happily be able to stay in the second house, which has plenty of privacy from the main house." "She'd love it if it could work out that way, though it remains to be seen if Jay will agree to that," the source added. Kristin Cavallari, Jay Cutler.

According to the documents, Cavallari began looking for a new home as early as November 2019 and said Cutler did not object to her doing so. In the filing, Cavallari said she told Cutler she had found a new house for herself and their kids, but claimed Cutler refused to release the money from their joint account. PEOPLE later confirmed that Cutler had agreed to release the funds for Cavallari to purchase her own home amid the split.
