The Kardashian sisters, plus the brother, have taken a win against their stepmother; ending their year-long legal battle to get their late father's diaries back from his widow. The siblings had filed a federal lawsuit against Ellen Pearson, claiming that the widow has been selling off family secrets from Robert Kardashian's diaries to the tabloids.

Some of the excerpts from the journals, including Robert Kardashian's private thoughts about his former wife, Kris, were leaked to U.S. tabloids. This fueled the Diary battle to regain their possession.

The diaries have been passed down to Kim, Khloe, Kourtney, and Rob in their Dad's will.

The complaint filed by the Kardashians in a California federal court sought copyright ownership over a number of heirlooms, including the famed attorney's diary/journal and several Kardashian photos, which they allege Kardashian's third wife has no right to possess.

The E! stars sought at least $500,000 in damages, claiming Pearson secretly hid the material from them to hatch a "despicable and unlawful scheme to hold in secret and convert, and now exploit...private personal and copyright protected" material-specifically property, like the holiday photo that showed the KUWTK stars when they were younger.

Robert Kardashian-best known for being a member of O.J. Simpson's "Dream Team" of lawyers representing him in his murder case-died in 2003 of esophageal cancer two months after tying the knot with Pearson.

According to the Kardashian's lawyers, a settlement has already been reached.

"Kris Jenner and Kimberly, Khloe, Kourtney and Rob Kardashian have settled their lawsuit against Ellen Pearson Kardashian. The diaries and photos have been returned to the Kardashians, and all other terms of the settlement are confidential. Ellen will continue her state court action for defamation," said Attorney Even Spiegel.

The ongoing defamation suit was filed by Pearson against the Kardashians. However, the family has already won a big part of that case and they plan to stick her with their attorneys' fees of more than $300,000.
