David, 53, is about to walk down the aisle with his 24-year-old girlfriend, Brooke. His 19-year-old daughter, Bree, claims Brooke is a “scheming gold digger” out for his money. David, who has been married twice before, says this time, he has protected his assets by having Brooke sign a prenuptial agreement.

TELL DR. PHIL YOUR STORY: Is your family a stressed mess?

Ann-Margaret Carrozza, an asset protection attorney and author of the book Love & Money: Protecting Yourself from Angry Exes, Wacky Relatives, Con Artists, and Inner Demons, joins Dr. Phil to weigh in on the prenup David and Brooke signed, and she offers the couple advice for what their prenup should include.

“This document, Brooke -- and I believe that you meant to show David and possibly Bree that your motives are pure and you're not in it for the money -- but because David gets everything and you get nothing, in the event of a dissolution, this could not be more unbalanced,” Ann-Margaret says. “It is vulnerable to being set aside by a court because it's a winner- take-all type of document.”
