Carmelo Anthony and La La are hashing out a temporary custody agreement in which she will get primary custody of their son ... TMZ has learned.
Sources close to the former couple tell us 10-year-old Kiyan will live with La La in NYC. He'll spend a couple of days a week with Carmelo.
We're told the 2 believe they can work out all the details without going to court ... it being done with their lawyers.
Both Carmelo and La La agree it's important they work out a structure for Kiyan so he's not whipsawed from place to place while they end their marriage.
