Jerry Buss structured his estate to keep the Los Angeles Lakers in the family after his death. But some of the safeguards meant to preserve that legacy have driven his children apart, according to trusts and estates attorneys.

Five of Buss’ six adult children want to sell the family’s remaining stake in the basketball team, valued by a separate recent transaction at $12.5 billion. Meanwhile, their sister Jeanie contends that her siblings do not have the legal authority to give up ownership and is opposing the sale, which would result in Jeanie Buss losing her position as governor of the Lakers.

The Buss stake in the franchise is owned by a family trust, which includes a “last man standing” clause, as described by sister Janie Buss to ESPN in 2017. That provision transfers a sibling’s equity upon their death to their surviving siblings rather than their own children, incentivizing the siblings to sell during their lifetime, Janie Buss told ESPN at the time.

Steven Fox, partner at Buchalter, said it’s common for parents passing down a business to want to limit the number of stakeholders. However, this type of clause is unusual, he said.

“I rarely draft that into estate plans, because just because one sibling has cancer and all of a sudden is going to die young, it’s not fair for their children to be divested,” he said. Fox, like the other attorneys who spoke to CNBC, has not seen the terms of the Buss family trust.

While few family businesses are like the Lakers, the broad strokes of the Buss family’s predicament are familiar, according to lawyers who spoke to CNBC. These succession conflicts are also likely to grow more common with the great wealth transfer underway and baby boomers passing on businesses to their children, said Sean Weissbart, partner at Blank Rome LLP.

Trusts and estates attorneys pointed to three steps that can make family business transitions smoother.

According to a letter written by Jeanie Buss’ lawyer, the trust requires two of Jeanie’s siblings and her co-trustees, Janie and Joey, to vote in a way that keeps her ownership above the 15% minimum for team governors.

Lawyers for Jeanie Buss and her siblings did not respond to requests for comment.

It’s common for parents to be torn between wanting to treat their children equally while acknowledging that one child is best-suited to run the business, Weissbart said. However, dividing decision-making power may not be in the children’s best interest, he added. He suggested allocating voting rights to one or two children who are best equipped to run the business while dividing the economic interest equally.

“Giving people the say over a multibillion-dollar business who don’t know how to actually manage it is detrimental to the business,” he said.

Weissbart and Fox both recommended placing the family business in a trust and naming only one child as trustee with the ability to make managerial decisions.

The shares are pooled into one so-called pot trust, and in the event of a sale, the proceeds are distributed to the individual siblings’ trusts, according to Fox. He said he sometimes adds an independent co-trustee such as an advisor from a bank or an advisory committee.

“It’s so much easier just to have one person dealing with it than to have to gain approvals from various children’s trusts or children themselves,” he said. “Siblings are difficult. We’re talking about a lot of bad blood.”

Still, Fox said most of his clients prefer a majority-rule approach, which he believes can worsen family ties.

“I always tell clients you’re going to destroy the relationship between your children. Once three of them gang up on one of them, the one that gets outvoted — and the business then gets sold — is going to harbor bad feelings the rest of their life against these three siblings,” he said.

Though Fox and Weissbart were largely in agreement, there isn’t widespread consensus.

George Taylor, partner at Brinkley Morgan, said instead of concentrating power with one sibling, he would recommend giving each child an equal say. Each sibling would be the trustee of an individual trust with equal shares of the business, and they could act through majority when selling.

“Obviously it’s more common than not that one child is left in control,” he said, “but this would be the ‘let’s get along, Kumbaya’ approach.”
