Jeanie Buss, the governor of the Los Angeles Lakers, has filed a legal petition in Los Angeles Superior Court seeking to prevent her five siblings from selling the family’s minority stake in the team. The move escalates a long-simmering family feud over the future of the franchise founded by their father, the late Jerry Buss.

The Buss Family Trust holds approximately 66% of the Lakers’ equity, split among Jerry Buss’s six children. Jeanie, who has run the team since her father’s death in 2013, controls the largest single share but not a majority. Her siblings—Jim, Johnny, Janie, Joey, and Jesse—voted earlier this month to sell their combined stake, which amounts to roughly 45% of the trust’s holdings. The vote, according to court documents, was 5-1, with Jeanie opposed.

In her filing, Jeanie argues that the trust’s explicit language requires unanimous consent for any sale of Lakers shares. “The trust was created to preserve the family’s legacy and ensure stable, long-term ownership of the Lakers,” the petition states. “A forced sale against the wishes of one beneficiary would contravene my father’s intent.”

Jeanie’s legal team is asking the court to issue an injunction blocking any transfer of shares until the trust’s terms can be clarified. They also seek a declaratory judgment that any sale requires her approval. The siblings, represented by attorney Mark H. Epstein, have countered that the trust permits a majority vote to liquidate assets. “The beneficiaries have a fiduciary duty to maximize value,” Epstein said in a statement. “A sale at current market prices, estimated at $5 billion for the team, would benefit all family members.”

The dispute has been brewing for years. Jim Buss, who previously served as executive vice president of basketball operations, was ousted from that role in 2017 after a series of poor draft picks and free-agent misses. Since then, Jeanie has consolidated power, hiring LeBron James in 2018 and winning the NBA championship in 2020. But the financial strain of the pandemic and rising player salaries have put pressure on the family’s liquidity.

Industry analysts say the Lakers’ value has skyrocketed from roughly $600 million when Jerry Buss died to an estimated $6.4 billion today, according to Forbes. A sale of the siblings’ stake could net each of them more than $500 million. Jeanie, however, has repeatedly stated she wants to keep the team in the family for generations.

The court will hear arguments on September 15. Legal experts note that trust disputes often hinge on nuanced language. “The key is what the trust says about sales,” said UCLA law professor Sarah H. L. Brown. “If it requires unanimity, Jeanie has a strong case. If not, the siblings may prevail.”

Meanwhile, the Lakers are preparing for the 2026-27 season, with a roster built around young stars Anthony Davis and Austin Reaves. The legal battle has not yet affected team operations, but sources close to the organization say morale is uneasy. “Everyone wants stability,” a team insider said on condition of anonymity. “This is a distraction nobody needs.”

Jeanie’s petition also requests that the court appoint a neutral trustee to oversee the trust’s administration until the dispute is resolved. The siblings have opposed that measure, arguing it would be an unnecessary expense.

The case, Buss v. Buss et al., is being watched closely by the NBA and other sports owners. The league’s bylaws require any sale of a controlling interest to be approved by the board of governors. But the sale of a minority stake does not require approval, unless it triggers a change in control.

If the siblings win, the new buyers could be a consortium of private equity firms or wealthy individuals. The Lakers have a long history of high-profile minority owners, including Magic Johnson and Philip Anschutz. But Jeanie has made it clear she wants to avoid that scenario.

“This is about more than money,” she said in a brief statement after filing. “It’s about honoring my father’s dream. The Lakers are not just a business; they are a part of Los Angeles’s soul.”

The courtroom battle is set to begin next month, with both sides preparing for a lengthy legal fight. For now, the Buss family’s internal war is spilling into public view, threatening to fracture one of sports’ most iconic dynasties.
