Halle Berry's checkbook is about to get a workout ... she's going to start paying baby daddy Gabriel Aubry $16,000/month in child support -- which comes to almost $200K a year.
A judge signed off on a settlement involving their custody dispute over 6-year-old Nahla.
L.A. Superior Court Judge Scott Gordon also ordered Berry to pay Aubry a retroactive payment of $115,000. And get this ... she also has to pay him $300,000 in attorney's fees.
Who knew ... lawyers are more expensive than kids.
