Lawyers tell CBS News the family will file a lawsuit in Los Angeles Tuesday, claiming Simpson still got paid, seeking to undo all the transactions related to the deal and, where appropriate, recover money for the Goldman family.
The Early Shownational correspondent Hattie Kauffman spoke exclusively with Goldman's sister, Kim.

The suit claims Simpson set up a bogus company so he could hide the money he received for "If I Did It," the book that was never released.
"He was given a book advance, as many authors are given when they write books," Goldman told Kauffman. "He was forwarded, I believe it was somewhere in the $800,000 range."
The suit asserts Simpson created a company "for the sole purpose of spiriting money from the hands of creditors," including the Goldmans.
"We believe there was a company called Lorraine Brook Associates. … The company is named after the middle names of both of his children, the killer's children."
The suit names Simpson and Lorraine Brook as defendants.
The book was to be published by Judith Regan, and the deal was to include a Fox TV special. But after a huge public outcry last month, the deal was cancelled last month.
Jonathan Polak, a Goldman family attorney, explained to Kauffman, "This lawsuit sets the stage for going after who we perceive to be the real villains in this: News Corp., Judith Regan, Regan Publishing."
The fallout from the book deal and other matters
"We believe that there were many people who were involved, including Judith Regan, who knew that this was going on," Goldman says.
"Look," Polak added, "the whole purpose of this book deal, the way it was set up, was to prevent the Goldmans and other creditors from being able to get at the money that was paid to Simpson."
The Goldman's have been pursuing Simpson for ten years. After his acquittal in the murders of Ron Goldman and Simpson's wife, Nicole Simpson, they won a civil suit against Simpson, but have never collected a penny.
Asked if she thinks this suit will lead to her family collecting any money, Kim Goldman responded, "Honestly, at this point, my family and I take much pride in the moral victories that we've been able to accomplish over the last 12 years."
During that time, Simpson's business deals, such as signing autographs for cash, amounted to small change.
In this case, he acknowledged in a radio interview that he made significant money, saying, "I was able to secure my homestead, pay off a whole lot of bills, and put my kids in a position to have their financial future totally secured."
Those words may now come back to haunt him, Kauffman points out.
Says Goldman, "He loves the fact that he can live his life and snub us, so at some point, if we are able to recover funds, good for us."
