Here is something that almost nobody warns affluent couples about, even when they are spending tens of thousands of dollars a year on sophisticated estate planning.
The more carefully you have structured your wealth to protect it from estate taxes, the more vulnerable you may be in a divorce. The trusts, the family limited partnerships, the GRATs and the SLATs and the QPRTs, all of those elegant tax planning vehicles you set up over the years, they were designed to protect your family's wealth from the IRS. They were not designed to be unwound under the time pressure of a divorce, and unwinding them often comes with consequences nobody anticipated when the plan was being built.
A high net worth divorce attorney recently described top end estate planning as estate planning 2.0 or 3.0. Sophisticated, layered, multi entity, designed to last for generations. When divorce hits, the question becomes how do we separate them. What are the tax consequences as a result of separating, or blowing apart, that estate plan.
That phrase, blowing apart, is the right one. This article walks through what actually happens when carefully constructed estate plans collide with a divorce, why the most expensive mistakes in high net worth divorce happen in this category, and what to know if any of these vehicles are part of your own picture.
Couples with significant wealth do not just open a brokerage account and call it a day. By the time a family has accumulated ten or twenty or fifty million dollars in net worth, the financial structure they are sitting on usually includes a layered set of vehicles designed to do three things. Reduce estate taxes that would otherwise apply to their estate. Protect assets from creditors and lawsuits. And transfer wealth to children and grandchildren in a controlled, tax efficient way.
These vehicles have names that sound like alphabet soup:
Each of these vehicles has a legitimate purpose. Each is the product of careful planning by estate attorneys, CPAs, and wealth advisors working together. And each was almost certainly built without divorce as the primary concern.
That last point is the one that catches people off guard. Estate planners are paid to think about death, taxes, and asset protection from third parties. They are not paid to think about what happens when the two people at the center of the plan stop being a couple. When that happens, the structures often have to be unwound, repositioned, or worked around, and the unwinding process is where the surprises live.
Most affluent couples have a revocable living trust as the foundation of their estate plan. It typically holds the home, the brokerage accounts, sometimes the business interests, and other major assets. The trust is revocable, which means either spouse, or both jointly depending on the structure, can change it, amend it, or dissolve it at any time. It is effectively a wrapper around the assets, designed primarily to avoid probate and provide for orderly succession.
In a divorce, a revocable living trust gets dissolved or restructured. The assets inside it are still subject to division according to whether they are marital or separate property. The trust itself does not really protect anything from the divorce. It is the underlying ownership of the assets that matters, and that gets determined under family law rules, not trust rules. The mechanics of unwinding the trust are usually manageable. The bigger conversation is just about what assets get allocated to whom.
The irrevocable trust problem is fundamentally different.
An irrevocable trust, by design, cannot be revoked or modified by the person who created it. That is the whole point. The grantor gives up control of the assets in exchange for the assets being legally separated from their estate, which provides tax benefits and creditor protection.
In a divorce, this creates a question that is much harder to answer cleanly. If the trust assets are no longer owned by the grantor in any meaningful sense, are they marital property. If the trust was created during the marriage and funded with marital assets, can the non grantor spouse claim a share. Does it matter if the spouse was a named beneficiary. Does it matter if the trust was created in a state with favorable trust laws. Does it matter if the family relied on distributions from the trust to fund their lifestyle.
The honest answer is, it depends, and the analysis is intricate. Different states have come to different conclusions. There are cases where irrevocable trusts have been protected entirely from divorce claims, and there are cases where courts have effectively unwound them or treated them as part of the marital estate. There are also cases in between, where the trust assets were not directly divided but the existence of the trust was considered when allocating other assets.
A family law attorney experienced in your state's case law on trusts is essential here. So is the estate attorney who built the structure in the first place. They need to be talking to each other, and they need to be talking to a Certified Divorce Financial Analyst who can model the financial consequences of different approaches.
One specific vehicle has caused more divorce friction in recent years than almost any other. The spousal lifetime access trust, or SLAT.
A SLAT is an irrevocable trust that one spouse creates for the benefit of the other. The grantor spouse, often the higher earning one, transfers assets into the trust. The beneficiary spouse can receive distributions during their lifetime. After the beneficiary spouse passes, the remainder typically goes to the children or grandchildren. The structure is popular because it removes assets from the grantor's estate for tax purposes while still allowing the family to indirectly access those assets through distributions to the beneficiary spouse.
The structure works beautifully as long as the couple stays married. The grantor spouse no longer owns the assets, but the beneficiary spouse can still draw from them, so the household effectively retains access. The estate tax exclusion has been used. Everyone is happy.
The problem with SLATs in divorce is straightforward. The grantor spouse irrevocably gave the assets to a trust for the benefit of the other spouse. The grantor cannot get those assets back. The beneficiary spouse, who is now the soon to be former spouse, is the one entitled to distributions for the rest of their life.
Cases involving SLATs sometimes see the grantor spouse spend six and seven figures on legal work trying to argue that the divorce should somehow undo the trust, that the original intent had been a joint family vehicle, that the assets should be brought back into the marital estate. Sometimes those arguments succeed in part. Often they do not, or they succeed only with substantial settlement offsets in other categories. The SLAT was designed not to be undone, and it works as designed even in this scenario, which is exactly the problem.
If you and your spouse have a SLAT and you are contemplating divorce, please understand that the conversation about it needs to happen early, with the right attorneys, before any decisions are locked in. This is a category where good professional advice is not optional.
The irrevocable life insurance trust, or ILIT, is another vehicle that surfaces often in these cases and is frequently overlooked.
An ILIT is a trust that owns a life insurance policy on the grantor. The death benefit, when it pays out, passes to the trust beneficiaries free of estate tax. ILITs are extremely common in high net worth estate plans, particularly for couples with large estates who want to provide liquidity to pay estate taxes when they die.
In a divorce, the ILIT becomes a curious question. The policy is still in force. The premiums continue to be due. The former spouse may still be a beneficiary, depending on how the trust was structured. The grantor's death will still trigger the death benefit, paid out according to the trust terms. The asset is a policy, but the policy is held by an irrevocable trust, so it cannot simply be cashed out and divided.
The mechanics of how an ILIT gets handled in a divorce vary by the trust language, the state, and the case. Sometimes the trust can be modified by agreement of all the parties involved. Sometimes it cannot, and the divorce settlement has to work around it. Sometimes the premium obligations become a negotiation point on their own.
If you find yourself unwinding sophisticated estate planning in a divorce, a few things matter.
The team. A high net worth divorce involving sophisticated estate structures requires more than a family law attorney. You need the estate attorney who designed the structure, ideally the original one if possible. You need a CPA who specializes in trust and estate taxation, because the tax consequences of different unwinding approaches vary enormously. You need a forensic accountant or business valuation expert if business interests or partnership interests are in play. And you need a Certified Divorce Financial Analyst to tie the financial picture together across all of these professionals.
Timing. The unwinding work cannot be rushed. The structures were built over years. The decisions about how to address them in a divorce settlement have multi decade consequences. Settlements that move quickly because one or both spouses want closure are often the settlements where these vehicles get handled poorly.
Documentation. Every original trust document, every amendment, every funding transaction, every distribution history, every tax filing related to the structures. All of it needs to be assembled. The professionals you bring in cannot give you good advice without seeing the full picture.
Honesty about what is recoverable. Some of these structures were genuinely designed not to be undone. Trying to undo them anyway is sometimes the right strategy, and sometimes it is throwing money down a hole. A good team will tell you which is which.
Many of these sophisticated structures were built with the next generation in mind. Dynasty trusts, generation skipping trusts, family limited partnerships with units gifted to children over time. The divorce conversation, in those families, is not just about the two spouses. It is about the broader family system. The children may have their own interests in the partnerships. The grandchildren may be remainder beneficiaries in the trusts. The estate plan reflects a multigenerational design.
In those cases, the divorce settlement can affect not only the two divorcing spouses but the inheritance and economic position of children and grandchildren who had nothing to do with the marriage ending. Settlements that fail to consider this dimension can create unintended consequences that play out over decades. The best teams hold the entire family system in view during the settlement conversation, not just the two people whose names are on the divorce filing.
Some couples, when they realize that their sophisticated estate planning is now creating divorce complications they had not anticipated, ask whether a postnuptial agreement can fix the problem. The answer depends on the state, the timing, and the specifics, and it is a conversation for your family law attorney. But it is worth raising as a possibility if the divorce conversation is still in the contemplation phase and not yet in active litigation. A well structured postnup, done with full disclosure and independent counsel for both spouses, can sometimes resolve the most contentious estate planning interactions before they become contested.
The estate planning that has served your family well for decades does not stop being important when a divorce begins. It just changes character. The vehicles that were designed to protect wealth from the IRS now have to be navigated under family law rules, in a setting they were not built for. The work is doable. It just requires the right team, the right time, and a clear eyed view of what you are dealing with.
If you and your spouse have a sophisticated estate plan and divorce is becoming a possibility, please reach out before any decisions are made. The conversations that happen at this stage shape outcomes for the rest of your life, and for the lives of the children and grandchildren the plan was originally built for.
