According to court documents, Brad Pitt is seeking joint custody of his six children in his split from Angelina Jolie.

The move comes after Angelina Jolie asked for full physical custody of all the children, who are aged 8 to 15.

Angelina Jolie cited “irreconcilable differences” when she filed to end the marriage on September 19.

Reports suggest that Brad Pitt is being investigated over an incident with his eldest son Maddox on a plane.

According to media, a child welfare agency in LA is examining what happened during the incident on a private flight in mid-September.

Angelina Jolie and Brad Pitt have reached a temporary agreement so the actor can visit his children while the welfare investigation continues.

California divorce courts generally favor joint custody, but the outcome of the plane row could affect the judge’s decision. Angelina Jolie and Brad Pitt may also hammer out a deal privately to avoid the matter being aired in public.

Brad Pitt’s custody request was included in his response to Angelina Jolie’s divorce petition. He revealed that they separated on September 15, one day after the alleged plane altercation.

The stars have been together since 2004 but only wed in August 2014, at their children’s urging. They grew close while filming the 2005 Mr. & Mrs. Smith, in which they played a couple in a stagnant relationship.

It was Brad Pitt’s second marriage, after a divorce from Jennifer Aniston, and Angelina Jolie’s third after Billy Bob Thornton and Jonny Lee Miller.

Brad Pitt, 52, and Angelina Jolie, 41, have six children together – Maddox, Pax, and Zahara, who are adopted, and biological children Shiloh and twins Knox and Vivienne.

They married privately at their French estate in Provence. Their children served as ring bearers and helped illustrate Angelina Jolie’s white Versace dress with their drawings.
