When someone messes with the legacy of Jimmy Buffett, especially after 46 years of marriage, you better believe it’s gonna get loud.

According to court documents obtained by PEOPLE, Jane Buffett, Jimmy’s longtime wife and the current beneficiary of his $275 million estate, is taking legal action to remove co-trustee Richard Mozenter for what she says is a blatant mishandling of the trust. And not just mishandling. We’re talking wasting money, dodging transparency, and straight-up retaliating with lawsuits like it’s a boardroom turf war instead of a trust meant to protect Buffett’s widow.

Jane’s had enough. And she’s not backing down.

In a July 21 filing in Florida, she accused Mozenter of launching a retaliatory legal campaign using trust funds without even asking her permission. Let that sink in. He allegedly spent money earmarked for Jimmy’s widow to fight Jimmy’s widow in court. If that’s not the most corporate, cold-blooded nonsense imaginable, what is?

The documents claim Mozenter has shown “little interest in sparing Marital Trust assets from the high cost of litigating three separate actions.” Three lawsuits. Funded from the very pool Jimmy Buffett set aside to take care of Jane. This isn’t a misunderstanding. This is scorched-earth, lock-the-doors litigation. And Jane’s lawyer made it crystal clear where she stands.

“Jane will not play into Mr. Mozenter’s hands by litigating this dispute in two separate courts across the country,” said attorney Matt Porpora to PEOPLE. “Instead, Jane is bringing the fight to Florida, where she and Jimmy called home.”

Mozenter was reportedly appointed co-trustee after Jimmy’s death, but Jane says he hasn’t acted like someone looking out for her best interests. In fact, she claims he’s been downright adversarial. According to earlier court filings, Mozenter and his attorney have allegedly refused to provide her with basic financial details about the trust and have treated her with open hostility.

Jane didn’t want this. She tried to do it the quiet way. According to sources close to the matter, she sent Mozenter the original California petition before she filed it and gave him time to step down voluntarily. Instead, he beat her to the punch and filed his own lawsuit to have her removed as co-trustee. That’s when Jane shifted the legal fight to Florida, the state where Jimmy spent most of his life and where she plans to finish this battle.

This whole thing reeks of greed and control. Mozenter’s side claims Jimmy wanted him in charge because he didn’t trust Jane to handle the finances. But if you know anything about the Buffetts, you know how close they were. Jimmy didn’t build Margaritaville with strangers. He leaned on Jane for decisions big and small for decades. If someone’s trying to paint her as unfit now, it’s hard to see that as anything but a power grab.

What we’re seeing play out here isn’t just a legal battle. It’s a blow to the image of what should have been a peaceful, well-earned retirement era for Jane Buffett. She stood beside Jimmy while he built an empire. Now she’s forced to fight to protect what’s rightfully hers because a guy her husband once trusted seems more interested in flexing legal muscle than honoring that legacy.

Sources close to Jane told PEOPLE that she “will not abide the waste of Jimmy’s money, which Jimmy expressly directed to be used to take care of her.” That’s the heart of it. Jane’s not out here trying to grab more than what was given. She just wants what her husband left her, without watching it get burned up in legal fees and ego games.

There’s a hearing set for August 14. Until then, this standoff keeps simmering. But one thing’s clear: Jane Buffett’s not going quietly. And if Jimmy were still here, he’d probably be pouring a margarita and telling someone to stop screwing around with his wife’s future.
