A trust can be hundreds of pages long. It can involve multiple trustees, generations of beneficiaries, carefully drafted distribution standards, and sophisticated tax planning.
And yet, the person whose wealth it governs may still struggle to answer a basic question:
What actually happens under this trust if my life changes?
That question is getting a very public stress test in New Jersey.
Two Sigma co-founder John Overdeck and his estranged wife, Laura Overdeck, are in the midst of what Laura’s attorney has described as the largest contested divorce in New Jersey history. The couple married in 2002, after Two Sigma was founded in 2001, and the central issue in their divorce trial is whether John’s ownership interest in the investment firm is marital property. Laura is seeking a share of the stake that her attorney values at approximately $6.2 billion. John’s attorney disputes both her claim to the stake and that valuation, and has said John proposed $723 million in tax-free equitable distribution.
But another dispute surrounding the divorce raises an important issue for anyone involved in sophisticated estate planning.
In separate litigation, Laura alleges that she signed documents in 2018 that allowed assets to be moved from New Jersey trusts into new irrevocable trusts in Wyoming. According to her complaint, she believed the restructuring was primarily intended to produce tax benefits. She later alleged that the new trust provisions had consequences she did not understand, including removing her as a beneficiary if either spouse initiated divorce proceedings. The law firm involved has disputed her claims, and the litigation remains ongoing.
The courts will ultimately determine what happened, which assets were involved, what the parties understood, and whether anyone acted improperly.
For advisors, the more durable lesson has nothing to do with who wins.
A technically sophisticated estate plan is not necessarily a well-understood estate plan.
“Irrevocable” does not mean “nothing can ever change”
The word itself sounds permanent.
When clients hear irrevocable trust, many understandably assume the document has been locked, the assets are untouchable, and the terms can never change.
The reality is more nuanced.
An irrevocable trust generally cannot be freely revoked or amended by the person who created it in the same way a revocable living trust can. But irrevocable trusts come in many forms and can be designed for many different purposes. Their tax treatment, beneficiary rights, trustee powers, creditor protections, and flexibility depend heavily on the trust’s language and applicable law.
Even the tax consequences are not as simple as “irrevocable means outside the estate.” Depending on the powers or interests retained by a grantor, some or all trust property may still be included in the grantor’s estate for federal estate tax purposes.
And, under the right circumstances, certain irrevocable trusts can be modified, reformed, divided, merged, or even decanted.
Trust decanting generally involves exercising authority under applicable law and the governing instrument to move assets from an existing irrevocable trust into another trust with different terms. The Uniform Law Commission describes its Trust Decanting Act as a mechanism for reforming or modernizing an irrevocable trust, although the rules and availability vary by jurisdiction.
That flexibility can be enormously valuable.
A trust created decades ago may need to respond to changes in tax law, family circumstances, asset composition, state law, or a beneficiary’s needs.
But flexibility creates another responsibility: clients need to understand when the economics or consequences of their plan have changed, even if the documents still contain the word “irrevocable.”
The trust document is only part of the plan
Imagine an advisor reviewing a client’s balance sheet and seeing: Irrevocable Trust: $18,400,000
That tells you remarkably little.
- Who created it?
- Who funded it?
- What assets are inside?
- Who are the current beneficiaries?
- Who are the remainder beneficiaries?
- Who can make distributions?
- Can the grantor replace the trustee?
- Does a spouse have an interest?
- What happens to that interest after divorce?
- What happens if a child dies?
- What happens if a beneficiary develops creditor problems?
- Which state’s law governs the trust?
- Are there powers of appointment?
- Can the trust be modified or decanted?
For many families, those questions matter more than the trust’s current account value.
An irrevocable trust is not simply another container on the household balance sheet. It is a set of instructions for how ownership, control, access, and inheritance should work across time.
If the client cannot explain those instructions, there may be a gap between having an estate plan and understanding the estate plan.
Life events are where trust design gets tested
Estate planning often begins with a snapshot.
A married couple has three children. The business is worth $10 million. Everyone lives in the same state. The children are minors. The couple has certain tax exposures. Family relationships are stable.
Then life happens.
- The business becomes worth $100 million.
- A child gets married.
- A beneficiary moves overseas.
- A spouse dies.
- Someone remarries.
- Tax laws change.
- A family moves from one state to another.
- A beneficiary develops special needs.
- A business is sold.
- A marriage ends.
The trust may continue operating exactly as drafted while the family around it becomes completely different.
That is why sophisticated planning should not be treated as a one-time drafting exercise.
It should be periodically stress-tested against the lives clients are actually living today.
Jurisdiction matters, but it is not a substitute for good planning
The Overdeck litigation also puts a spotlight on the increasingly important role of trust jurisdiction.
Families are not always limited to establishing trusts in their home states. Depending on the circumstances, planners may consider jurisdictions with laws designed to support long-duration trusts, asset protection, trust administration, privacy, or favorable tax treatment.
Wyoming, for example, has enacted laws allowing qualified spendthrift trusts and has eliminated certain traditional limitations on the duration of noncharitable trusts.
These features can be useful planning tools. But a favorable jurisdiction should not be confused with a force field.
Changing the state governing a trust does not eliminate the need to understand how assets were transferred, who the beneficiaries are, what powers were granted, what duties trustees and other fiduciaries have, or how the structure interacts with other areas of law.
The more sophisticated the strategy becomes, the more important the explanation becomes with it.
Clients should understand consequences, not clauses
Most clients will never become trust and estate attorneys.
They should not have to.
The goal is not for a client to explain the finer points of discretionary distribution standards or recite provisions of a 90-page trust agreement.
They should understand the consequences.
An advisor reviewing an irrevocable trust with a client might start with questions such as:
- Who benefits from this trust today?
- Who controls investment and distribution decisions?
- What can you still control, and what have you permanently given up?
- Under what circumstances could you or your spouse stop being a beneficiary?
- What happens when you die?
- What happens when your spouse dies?
- What changes if either of you remarries?
- How are your children protected if they divorce?
- Can future descendants become beneficiaries?
- What happens if the trustee can no longer serve?
- Which provisions can potentially be changed, and which cannot?
- When was the last time this trust was reviewed against your current goals?
A client who can confidently answer those questions is in a very different planning position from a client who simply knows that “the attorneys set up a trust.”
Advisors can help close the understanding gap
Financial advisors are not substitutes for estate planning attorneys, nor should they be interpreting legal documents beyond the boundaries of their professional role.
But advisors are uniquely positioned to recognize when the legal architecture of a client’s estate no longer appears aligned with the rest of the financial picture.
They often see the changes first.
They know the business has appreciated dramatically.
They know a daughter is getting married.
They know the client moved from New York to Florida.
They know a spouse recently died.
They know the family sold a company.
They know an old trust has become one of the largest assets on the family’s balance sheet.
Those are opportunities to bring the client’s attorney, tax professional, and other specialists back into the conversation.
Technology can make that process easier by helping advisors move beyond simply cataloging that a trust exists. Modern estate planning tools can help surface ownership structures, beneficiaries, trustees, distribution provisions, and relationships across a family’s broader estate plan, making it easier to identify questions worth revisiting with counsel.
Because the question should not stop at: “Do you have an irrevocable trust?”
The better question is: “Does your client understand what that trust will actually do when life changes?”
Complexity should create clarity, not obscure it
The outcome of the Overdeck litigation is still unknown. Allegations remain disputed, and the courts will determine the legal and factual issues involved.
But advisors do not need to wait for a verdict to take something useful from the case.
Families are using increasingly sophisticated strategies to transfer wealth across generations, reduce taxes, protect beneficiaries, manage concentrated assets, and preserve family legacies.
That sophistication can be powerful.
It can also create distance between the documents clients sign and the outcomes they believe they are creating.
The best estate planning should do the opposite.
The more complex the structure, the clearer the client should be about what it means.
For advisors, that creates an opportunity to turn estate planning from a stack of documents into an ongoing planning conversation, one that evolves alongside the family it was designed to serve.
