An unexpectedly trivial feud erupted among five siblings, each promised a $10 million mansion during a dramatic family “trust reveal.”

These anonymous heirs were spotlighted in a recent Wall Street Journal article that delves into the timing and manner in which the ultra-wealthy disclose their inheritance plans to their children.

Jen Galvagna, who leads the trust, estates, and tax division at the Bank of America, shared details of the anonymous family’s discord.

She explained to the publication that each of the five heirs was assigned one of their family’s global residences. Three of these properties were valued at about $10 million each, selected to maintain an appearance of fairness by the parents.

To preempt any familial disputes, the parents structured the trust so that if one sibling received a pricier home, their portion of liquid assets would decrease accordingly.

Despite these efforts, Galvagna noted that tensions quickly escalated, with insults and accusations being exchanged.

‘People were questioning why they got this house, and not the other house’, she told the outlet. 

The ungrateful siblings nitpicked over the location of their respective mansions – with one on water the most sought after – as well as how well they’d been renovated.

HBO’s hit drama Succession saw the offspring of media magnate Logan Roy (played by Brian Cox, center) locked in a series of petty and personal squabbles over their inheritance. And the super-rich behave just the same way in real life, experts say 

The enviable drama calls to mind HBO’s hit series Succession, in which the cosseted and lazy children of media magnate Logan Roy (Brian Cox) fought over what they perceived to be their dues. 

According to those who spoke with the Journal, the most popular structure for the uber rich involves a dynasty trust. 

Those trusts enable their holders to move wealth down through a potentially infinite number of generations in a way that can legally avoid estate and inheritance taxes.

Galvagna told the outlet that she worked with a trust that was set up specifically to help fund a child’s equestrian hobby. 

The fund was filled with $75 million and allowed the client’s daughter to buy and stable horses, cover medical bills, hire instructors and insure the animals. 

Galvagna said the trust allowed for further distributions tied to the girl’s education, health and other expenses. 

Another family put an emphasis on money being paid out of their fund specifically for travel, in the hopes that their children would see the world. 

Galvagna said that the fund allowed for a $300,000 annual disbursement just for vacations.

Other experts say ultra-rich parents are keen to provide for their children while emphasizing the need for them to work hard and contribute to society.  

Some trusts will match an heir’s existing income to motivate them to progress through their career and climb the ladder.

Others pay out bonuses if a heir graduated with a certain grade average, or if they earned a four-year degree.  

They are typically stuffed with stocks, bonds, cash, properties and family heirlooms but some occasionally contain businesses or other assets. 

Sunil Tolani, a hotel entrepreneur, told the outlet that a Holiday Inn Express he owns and other hotels are all in a trust fund for his sons. 

As well as the properties, his personal homes, gold jewelry, watches and his wife’s Hermes handbags are all included. 

Tolani said: ‘The biggest gift you can give to the people you love is to create an estate plan.’

Luke Jernagan works with families in breaking the news of the value of their trust funds to their children.

He told the outlet that he helps write scripts for them and his firm will actually host the meeting, saying: ‘I’ve never been to one of those where people weren’t teary.’

According to the outlet, one of the reasons families start to disclose the true values of the funds is if they suspect one of their children is on the verge of marrying. 

Failing to have that talk can prove difficult, a Fidelity survey found this year that 68 percent of parents hadn’t told their children what they would inherit. 

Over half hadn’t discussed their net worth with their kids, fearing that their may blow the money.  

According to Cerulli Associates, over $100 trillion will be passed down to younger generations and to charities until 2048.  Around $62 trillion will come from high-net-worth individuals. 

Trusts and estates have already generated $290 billion in income for beneficiaries this year alone.  If that figure keeps on track, it will blow a record that dates back to 2003, according to tracker IBISWorld.
