U.S. Bankruptcy Judge Jay Cristol Monday approved the division plan subject to the court's supervision, CNN reported.
Last month, Fred Goldman, Ron Goldman's father, won the right to pursue publishing rights of Simpson's alleged hypothetical account of the slayings.
After the hearing Monday, Fred Goldman said his family has spent "13 years of trying to get some justice for Ron" and the latest ruling was "the first time we had any light at the end of that tunnel."
Denise Brown, sister of Nicole Brown Simpson, who sought but did not get a portion of the proceeds, called the account "a manual for murder" that should not be published.
The remaining 10 percent of the proceeds will go to trustees handling creditors' claims against the company whose only asset was the book.
