Halle and Olivier filed for divorce at almost the exact same moment back in October 2015 ... she filed as the petitioner and he also filed as the petitioner seeking a divorce.
Under California law only one person can be the petitioner, and Olivier agreed to give Halle the honor.
Under the settlement, they will share physical and legal custody of 3-year-old Maceo.
For some reason, they decided to only deal with the custody issues and the property settlement is still unresolved. It's weird, because our sources say there's a prenup so there shouldn't be big issues.
