Halle Berry and Olivier Martinez plan to enter mediation.
The estranged couple - who separated recently filed for divorce after two years of marriage - are eager to keep their split as amicable as possible for the sake of their two-year-old son, Maceo, and have already agreed to seek professional help to iron out a fair custody agreement.
A source said: "There's zero bitterness."
The 49-year-old French actor is currently staying at the Oscar winner's second home in LA's Benedict Canyon.
The source added to Us Weekly magazine: "They want Maceo to have a place to be with Olivier. They want what's best for their son."
The 'Extant' actress reportedly decided to finally pull the plug on their romance after an LAX airport employee recently filed a $5 million lawsuit against them, claiming the 'Dark Tide' actor allegedly shoved him to the ground with a baby car seat in January.
A source previously said: "When she found out about the lawsuit, she was done."
California also came between the duo, as Olivier was very disappointed when a judge blocked Halle from relocating to Paris with him because of her seven-year-old daughter Nahla with ex-boyfriend Gabriel Aubry.
