How Much Money is Arnold's Love Child Entitled To?

ET sits down with family attorney Robert Brandt to examine how much of Arnold Schwarzenegger's fortune his love child could get and to explore the possibility that the actor payed hush money to his mistress.

"Child support guidelines will determine the amount of monthly child support that must be paid to this child," said Brandt, an attorney at Feinberg, Mindel, Brandt & Klein in Los Angeles. "The court might take into account Arnold's lifestyle, but for the most part they'll take into account his income."

Schwarzenegger's child was fathered out of wedlock more than a decade ago and Brandt said that fact makes it a very likely there was some agreement between the actor and the child's mother to keep the event quiet. "In these types of cases, when you're talking about a public figure, a celebrity, it is not uncommon at all for there to be a side agreement, an understanding, a confidential agreement between the parties that would keep it out of court, in which there would be some payment made by Arnold to the mother of the child, and an understanding that she would keep it quiet, that she wouldn't go public."

The attorney said given the fact that Schwarzenegger and Maria Shriver are both huge celebrities, they will probably try to settle the matter out of the media. "I think the key in this case is we're talking about two incredibly public figures. We're talking about a child of the Kennedy family, the Kennedy clan, the Kennedy legend. We're talking about Arnold Schwarzenegger, one of the most well-known actors in the world. My guess is they're going to do everything they can to keep this as confidential, as quiet as possible, work it out and settle."
