Ariel Winter's Dad Now Controls Her Estate

Ariel Winter's dad now has control over her estate -- namely her finances -- which was part of the settlement struck today outside the courtroom ... BUT the dad can't make a move without dealing with a group of professional advisers who work directly for Ariel.

Glenn Workman just got the green light from the judge to manage Ariel's money. Interesting ... considering Glenn filed a declaration in the case calling Ariel "my retirement surprise child." But here's the deal ... Glenn can't make business decisions without first discussing them with Ariel's lawyer, Blair Berk and others. If he disagrees with the advisers, a judge is the tiebreaker.

Under the terms of the settlement, Ariel's sister, Shanelle, will remain the guardian of Ariel, meaning Ariel's mom, Chrystal, has been cut out of everything.

The move is temporary, but could become permanent in March.

The settlement was struck before a court fight over the guardianship ... a fight that promised to be ugly.

After today's settlement, Ariel's brother Jimmy Workman told reporters his family would be seeking therapy and counseling to get back together. Jimmy said his father is "happy and thrilled" with the settlement and so is his mom.
