Are you making these costly estate planning mistakes? Experts reveal how to avoid financial disaster

When it comes to estate planning, the hope is simple: our wishes will be honored, our loved ones cared for, and our legacy preserved.

Ideally, all this will happen without confusion, drama, or a courtroom showdown.

Yet, as the old saying goes, "The best-laid plans of mice and men often go awry."

Even the wealthy and powerful, surrounded by teams of experts, can find themselves tangled in expensive, public estate battles.



If you think estate planning is only for the ultra-rich, think again. With nearly $70 trillion expected to transfer between Baby Boomers and their heirs by 2042, according to Cerulli Associates, the stakes have never been higher. And as Americans live longer, face cognitive decline, and accumulate more complex assets, the potential for family feuds and legal disputes only increases.

Lessons from the big names: What went wrong?​

Consider Rupert Murdoch, the media mogul, whose attempt to shift control of his empire to his favored son ended in a legal mess. Or Jimmy Buffett, whose $275 million estate is now embroiled in lawsuits between his widow and longtime business manager. If billionaires with armies of lawyers can go wrong, it’s a wake-up call for the rest of us.

What happened in these cases? Murdoch tried to alter an irrevocable trust designed to give his four children equal voting rights, aiming to give his eldest son full control instead. The court ruled this as “bad faith,” finding that the change prioritized one child’s interests over the others.

In Buffett’s case, naming co-trustees with equal authority but no clear way to resolve disputes led to gridlock and legal battles.

The most common estate planning mistakes—and how to avoid them​

  1. Assuming family harmony will last forever
    It’s natural to hope your heirs will always get along, but money and grief can bring out the worst in even the closest families. "Effective estate planning accounts for the moment when family members no longer see eye to eye, rather than assuming harmony will last," says Kevin Ghassomian, partner at Venable LLP.

  2. Naming multiple co-trustees without a tie-breaker
    Many parents try to treat their children equally by naming them all as co-trustees. However, attorney Joseph Fresard warns that “Each additional trustee greatly increases the chance of litigation, as disagreements between trustees often need court intervention to resolve.” Instead, consider naming one trustee or adding a neutral third-party tie-breaker.
  1. Overlooking the importance of structure and governance
    A well-drafted trust isn’t just about naming beneficiaries and trustees. It should also include decision-making processes, deadlock resolution methods, and contingency plans. "Even well-intentioned people can disagree, and when they do, the document should offer a way forward that protects both relationships and the administration of the trust," says Ghassomian.
  1. Not understanding the limits of irrevocable trusts
    Irrevocable trusts can be powerful tools for asset protection and tax planning, but as the name suggests, you give up control over the assets. Be sure you understand what you're giving away and that you’re comfortable with it.

  2. Ignoring state laws and tax implications
    Trust laws and tax rules vary widely by state. Some states, like Nevada, offer strong asset protection, no state income tax, and more flexible trust laws. It may be worth consulting an expert to see if setting up a trust in another state could benefit your family.


A will is a great start—it specifies who gets what when you’re gone. But it’s just one piece of the estate puzzle. Trusts provide greater control over how and when your assets are distributed, help you avoid probate, and protect assets from creditors.

However, trusts aren’t one-size-fits-all. There are different kinds of trusts like irrevocable trusts, which generally can’t be altered. Choosing the right one depends on your goals, assets, and family dynamics.

Communication is one of the most overlooked aspects of estate planning. Surprises are great for birthdays, not inheritances. Consider holding family meetings to explain your wishes, reasoning, and the roles you’ve assigned. This can help manage expectations and head off conflicts before they start.

Estate planning is complex, and the stakes are high. A qualified estate planning attorney and a trusted financial advisor can guide you through the options, avoid common pitfalls, and craft a plan that reflects your values and protects your loved ones.
