The dragging-on divorce and custody battle between Brad Pitt and Angelina Jolie is set to go to a trial next month because they can't agree about the future of their six children despite two years of lawyering and leaking.

Axar.az reports that if Pitt and Jolie have their way, it will all happen behind closed doors. If it happens at all.

The couple could still reach an agreement out of court and put the messy breakup of their family behind them but lately, their ability to see eye-to-eye seems to have deserted them.

Still, a source familiar with the situation but not authorized to speak publicly said both sides "are still working together to find an out-of-court settlement.”

The two stars' legal teams have been in fierce negotiations since September 2016, when Jolie filed for divorce citing irreconcilable differences and "the health of the family" after 12 years together, two of those years in what we later learned wasn't wedded bliss.

Their custody dispute comes down to this: She wants sole physical custody of their six kids, ranging in age from 10 to 17; he wants to share physical custody.

Now, according to a document filed Monday in Los Angeles County's Family Court, Pitt and Jolie have asked for an extension to June 30, 2019, on the appointment of retired Judge John Ouderkirk as a temporary "private" judge in their case.
