The couple, who are going through divorce proceedings, was scheduled for a conference management hearing on Wednesday where Judge Thomas Anderele denied Baumgartner’s request to move out of the home in August, according toFox NewsandYahoo.

The meeting comes after PEOPLE obtained court documents filed on June 30, in which Costner’s legal team claimed that Baumgartner allegedly “grasps at straws with one baseless argument after another,” as to why she should be allowed to stay in his Santa Barbara home.

Christine arrived by limousine at the Santa Barbara Courthouse and is met by a woman presumed to be her lawyer.

Costner, 68, “respectfully requests that Christine be ordered to vacate his separateproperty residenceforthwith and no later than July 13, 2023," the document states.

Baumgartner has reportedly remained in the home since filing for divorce on May 1, despite a clause in her prenuptial agreement that he claims requires her to leave within 30 days. That deadline has since passed.
