Adrienne Maloof & Paul Nassif -- Money Truce in Divorce

Adrienne Maloof and Paul Nassif agreed ... they would not try to screw the other out of money in their divorce ... striking a deal that essentially leaves both parties with whatever they came into the marriage with ... TMZ has learned.

We broke the story ... the 'Real Housewives' stars settled their divorce this morning after a breakup that got downright nasty.

Sources tell us the agreement was reached after both families stepped in to help mediate ... with Paul's brother, Chris Nassif, and Adrienne's brother, Joe Maloof leading the charge.

Of course, money COULD have been a major issue ... since they're both incredibly wealthy. But sources close to the former couple tell us the two hammered out a deal that will allow them to each keep the assets they brought into the union ... and split everything else they acquired during the marriage right down the middle.

As for custody of the couple's 3 sons ... we're told Adrienne and Paul agreed to a deal that is "very close to 50/50 custody."

One source close to the couple tells us, "They're both happy ... and they just want to move on with their lives."
