Dr. Paul Nassif wants way more than the custody arrangement he just settled for -- which gives Adrienne Maloof the lion's share of time with their 3 kids -- we've learned he's gunning for a 50/50 split.
We broke the story, Nassif and Adrienne Maloof reached a temporary deal Monday ... in which Adrienne gets weekdays and every other weekend with the children.
As part of the deal, Maloof agreed to drop the temporary restraining order against Nassif that barred him from interacting with the kids without a monitor present.
Short story -- while Adrienne's allegations were pending, Paul was in a tight spot. Although he denies the claims ... he had to cut a deal now, or not see the kids.
Sources familiar with the situation tell TMZ ... Paul is getting his ducks in a row to fight any lingering allegations against him, and he's going back to court in January with the end game of joint custody.
