Jimmy Buffett built an empire around the laid-back “Margaritaville” lifestyle, but his $275 million estate has become anything but relaxing for his family. The legendary musician’s widow and longtime business manager are now locked in a high-stakes legal battle that might have been avoided with better planning and—most importantly—better communication.
This story is a powerful reminder that having legal documents in place is only part of a truly effective estate plan. In this article, we’ll unpack what went wrong in the Buffett estate, the overlooked piece that led to this heartbreaking family conflict, and how a proactive and comprehensive approach to planning can protect your family from the same fate.
What Happened
To be clear, Jimmy Buffett didn’t completely neglect his estate planning. In fact, he did many things right. Reports indicate he created a will over 30 years ago and updated it regularly—including just months before his death in 2023. He also created a marital trust intended to provide for his wife, Jane Buffett, during her lifetime, with the remainder to go to their three children.
Buffett named both his wife, Jane, and his longtime accountant and business manager, Richard Mozenter, as co-trustees of the trust.
But things quickly unraveled.
In June 2025, Jane Buffett filed a lawsuit seeking to remove Mozenter as co-trustee. She alleged he was “openly hostile and adversarial,” refused to provide her with basic financial information, and was collecting $1.7 million annually in management fees that she felt were undeserved. Jane also claimed her projected income from the trust was only $2 million per year—an alarmingly low figure for a $275 million estate, representing less than a 1% return.
Mozenter fired back with his own lawsuit, alleging that Jimmy Buffett had intentionally structured the trust to limit Jane’s control due to longstanding concerns about her financial management. He claimed Jane had been uncooperative and disruptive to his efforts to manage the trust.
Now, a trust designed to care for Jane and honor Buffett’s legacy is at the center of a legal war—costing millions in fees, eroding family unity, and casting a long shadow over Buffett’s memory.
Why Legal Documents Aren’t Enough
So what went wrong?
It wasn’t that Jimmy Buffett failed to plan. It’s that his planning focused on documents instead of communication.
The core of this conflict lies not in legal errors but in a lack of shared understanding. Jane appears to have been blindsided by the level of control (or lack thereof) she had over the trust. Mozenter, on the other hand, believes he’s honoring Buffett’s wishes by limiting Jane’s influence.
Whether or not Jimmy explicitly told either party what to expect is unclear—but what is clear is that the lack of open conversation led to wildly different interpretations of his intentions.
And this is where many estate plans break down.
You can have perfectly executed legal documents—wills, trusts, powers of attorney, and more—but if the people involved don’t understand their roles, the purpose of the plan, or each other’s expectations, the plan is vulnerable to dispute. In many cases, that leads directly to the courthouse.
The Emotional and Financial Toll of Conflict
Estate disputes like this one are far from rare. In fact, they’re becoming more common as massive generational wealth transfers take place. According to Cerulli Associates, approximately $124 trillion will be passed down through estates between now and 2048.
And without thoughtful, relationship-centered planning, much of that wealth could be lost to legal fees, taxes, and infighting.
In the Buffett case, the financial costs are already mounting. Jane’s trust is paying $1.7 million per year to a trustee she is now suing. Additional millions will be spent in legal fees. And the emotional toll—public court battles, strained relationships, stress, and grief—is immeasurable.
