Jeff Younger has been battling his ex-wife Dr Anne Georgulas in a Dallas family court as part of their bitter custody fight over whether their child James has gender dysphoria.
Judge Kim Cooks ruled on Thursday that the divorced parents will have joint conservatorship over their child.
It means they will have to make joint medical decisions regarding their child, which includes whether James should undergo hormone replacement therapy to transition to a girl.
They will also have to jointly agree on haircuts for the child, as well as dental and psychiatric care.
The decision comes after a jury ruled earlier this week in favor of giving sole managing guardianship of James and twin brother Jude to their mother.
Georgulas, who is a pediatrician, has argued that James is transgender and wants the child to transition to a girl named Luna.
Her ex-husband, however, doesn’t believe James has gender dysphoria and that his child is just experiencing some confusion with gender.
He has accused Georgulas of forcing James to socially transition into a girl by making the child wear dresses.
Just moments before the judge’s decision was handed down, Younger told DailyMail.com outside court that he didn’t expect the proceedings to go in his favor. Watch video.
