Robin Thicke, Paula Patton ... Divorce is a Done Deal

Robin Thicke and Paula Patton have settled their divorce case ... TMZ has learned.

Paula filed legal docs Tuesday declaring they have reached a property settlement as well as a custody arrangement for their 4-year-old son Julian.

The terms of the settlement are private. There's an indication from the legal docs Paula is getting primary custody, but it's not spelled out specifically. They've also agreed on the terms of spousal and child support.

The divorce does NOT become final until April 14, 6 months after Paula filed. At that point they will be officially single, but now it's just a matter of time.
