Disclaimer Trusts

Disclaimer-trust calls come from couples planning around an uncertain future. The federal estate-tax exclusion is at a historically high level today, but the surviving spouse may face dramatically different tax exposure depending on when the first death occurs and what the law looks like at that time. The surviving spouse may need all the assets for living expenses, or may not. The blended family dynamics may make full outright transfer to the surviving spouse complicated. The high-net-worth couple wants flexibility to optimize the marital and credit-shelter portions of the estate based on what circumstances actually present at the first death.

A disclaimer trust addresses exactly this uncertainty. The basic structure leaves assets outright to the surviving spouse, with a backup provision that any assets the surviving spouse disclaims under N.J.S.A. 3B:9-1source et seq. drop into a credit-shelter trust for the children. The surviving spouse has a limited nine-month federal disclaimer window after the first death, so the plan needs to be drafted in advance and counsel should be contacted immediately after death if a disclaimer may be useful. The work is drafting the disclaimer provisions to actually work the way they're intended when the time comes.

What Is a Disclaimer Trust?

A disclaimer trust is an estate planning structure that gives the surviving spouse the ability to direct assets into a trust after the first spouse's death, rather than receiving everything outright. The surviving spouse "disclaims" (refuses to accept) a portion of the inheritance, and the disclaimed assets pass into a trust created under the deceased spouse's will or trust document. This mechanism provides flexibility that traditional A/B trust structures do not, because the decision about how much to fund the trust is made after the first death, when the surviving spouse has full information about the tax laws, the size of the estate, and their own financial needs.

Disclaimer trusts are particularly useful for New Jersey families because the federal estate tax exemption has changed significantly and repeatedly over the past two decades. A plan that locks in a specific funding formula based on today's exemption amounts may produce results that are suboptimal or even harmful under future tax law. A disclaimer trust avoids this problem by deferring the key decision to the time when it can be made with certainty.

How a Disclaimer Trust Works

The mechanism is simple to state but deliberate in its timing. Every step is built so that the single decision that drives the tax result — how much, if anything, to move into the trust — is deferred until the surviving spouse can see the estate, the law, and their own circumstances clearly. The five steps below trace that arc from drafting to the second death:

• Step 1: The estate plan (will or revocable trust) includes a provision creating a disclaimer trust. The trust terms are fully drafted and ready to receive assets, but the trust is not funded during the couple's joint lifetime
• Step 2: When the first spouse dies, the surviving spouse inherits the estate under the terms of the will or trust
• Step 3: Within nine months of the first spouse's death, the surviving spouse may disclaim some or all of the inherited assets. The disclaimed assets pass into the disclaimer trust rather than to the surviving spouse outright
• Step 4: The disclaimer trust holds and manages the disclaimed assets for the benefit of the surviving spouse and other beneficiaries (typically children) according to the trust terms
• Step 5: Upon the surviving spouse's death, the assets in the disclaimer trust pass to the ultimate beneficiaries (typically children or grandchildren) without being included in the surviving spouse's taxable estate

Tax Planning Benefits

The primary tax advantage of a disclaimer trust is that it allows the surviving spouse to take advantage of the deceased spouse's federal estate tax exemption without committing to a specific funding amount in advance. If the exemption is high at the time of the first death and the estate is well below the threshold, the surviving spouse may choose to disclaim nothing and inherit everything outright. If the exemption is lower or the estate has grown substantially, the surviving spouse may disclaim a larger amount to help ensure that the deceased spouse's exemption is fully utilized.

Although federal portability now allows a surviving spouse to use the deceased spouse's unused exemption without a trust, a disclaimer trust offers additional advantages that portability does not:

• Protection from future appreciation: Assets in the disclaimer trust, including all future growth, are excluded from the surviving spouse's taxable estate. With portability alone, the deceased spouse's exemption amount is fixed at the date of death and does not grow
• Creditor protection: Assets in the disclaimer trust are generally protected from the surviving spouse's creditors
• Generation-skipping tax planning: The deceased spouse's GST tax exemption can be allocated to the disclaimer trust, which is not possible through portability alone
• State tax planning: Although New Jersey eliminated its estate tax, residents with ties to other states or property in states with estate taxes may benefit from state-level tax planning through a disclaimer trust

Requirements for a Valid Disclaimer

Under both federal tax law (IRC § 2518source) and New Jersey law (N.J.S.A. 3B:9-1 et seq.source), a disclaimer must meet specific requirements to be legally effective:

• The disclaimer must be in writing
• It must be delivered to the personal representative, trustee, or holder of the property within nine months of the date of death
• The disclaimant must not have accepted the interest or any of its benefits before disclaiming
• The disclaimed interest must pass without any direction on the part of the disclaimant to either the surviving spouse's trust or to other beneficiaries as specified in the estate plan

The nine-month deadline is strict and cannot be extended. This means that the surviving spouse should contact legal and financial advisors promptly after the first spouse's death to evaluate the financial and tax situation and determine the optimal disclaimer amount.

When a Disclaimer Trust Makes Sense

A disclaimer trust earns its place when the right amount to shelter at the first death genuinely cannot be known in advance — because the estate may grow, the law may change, or the surviving spouse's needs may shift. In those situations the flexibility is not a luxury; it is the difference between a plan that fits the facts as they actually unfold and one that locks in a guess. The profiles below are the ones where that flexibility tends to matter most:

• Married couples whose combined estate may or may not exceed the federal estate tax exemption, depending on when the first spouse dies
• Families who want flexibility to respond to future changes in tax law
• Couples where the surviving spouse is financially sophisticated and will work with professional advisors to make an informed post-death decision
• Situations where the couple does not want to irrevocably commit assets to a credit shelter trust during their joint lifetimes
• Blended families where the surviving spouse's needs must be balanced against the interests of children from a prior marriage

Limitations and Considerations

A disclaimer trust is not the right choice for every family. It requires the surviving spouse to make a consequential financial decision during a period of grief and transition. If the surviving spouse fails to act within nine months, the opportunity is lost. For families where one spouse is less financially engaged or may not have access to professional advisory support, a mandatory credit shelter trust may be more appropriate because it operates automatically without requiring any post-death action.

The honest trade-off, then, is flexibility against the burden of a deadline. A disclaimer trust hands the surviving spouse the most informed possible decision — but it hands it to them at the hardest possible time, and it does nothing on its own if they let the nine months pass. A credit shelter trust reverses that trade: it gives up the post-death choice in exchange for funding that happens automatically, with no action required from a grieving spouse. Neither is categorically better. The right answer depends on how much the family values flexibility, how confident they are that the surviving spouse will have capable advisors at the ready, and how much uncertainty surrounds the estate's future size and the law itself. We work through that comparison with each family rather than defaulting to one structure.

The Nine-Month Disclaimer Window: What the Surviving Spouse Must Do

The nine-month deadline imposed by IRC § 2518source and N.J.S.A. 3B:9-1 et seq.source is the most critical operational element of a disclaimer trust. Contact counsel immediately after death; during this period, the surviving spouse must:

• Assess the estate: Work with the estate planning attorney and financial advisor to determine the total value of the estate, including retirement accounts, life insurance, real property, and investment accounts
• Evaluate the tax landscape: Determine the current federal estate tax exemption, whether portability should be elected (by filing Form 706), and whether a disclaimer provides benefits beyond what portability alone would offer
• Determine the disclaimer amount: Decide how much of the inherited estate to disclaim into the trust. This decision depends on the surviving spouse's own financial needs, the size of the estate relative to the exemption, the ages and needs of other beneficiaries, and the surviving spouse's comfort level with having assets held in trust rather than owned outright
• Execute the disclaimer in writing: The disclaimer must be delivered in writing to the personal representative, trustee, or other holder of the property. It must be an irrevocable and unqualified refusal to accept the interest
• Avoid accepting benefits: The surviving spouse must not have accepted the disclaimed interest or any of its benefits before making the disclaimer. This means the surviving spouse should not deposit inherited funds into their personal account, use inherited property, or exercise control over assets they intend to disclaim

The nine-month clock begins on the date of death, not the date of probate or the date the surviving spouse learns of the inheritance. There are no extensions, even for good cause. Families who choose a disclaimer trust strategy must understand that the surviving spouse will need to make a consequential financial decision during a period of grief, and they should identify the advisory team who will help make that decision well before it is needed.

New Jersey-Specific Tax Considerations

New Jersey eliminated its estate tax effective January 1, 2018, which significantly changed the calculus for disclaimer trusts in the state. Before 2018, New Jersey imposed an estate tax with an exemption of only $675,000, making credit shelter and disclaimer trusts essential for middle-class families. Today, the primary tax driver for disclaimer trusts in New Jersey is the federal estate tax, with its 2026 basic exclusion amount set at $15 million per individual under the OBBBA and indexed after 2026.

However, New Jersey still imposes an inheritance tax under N.J.S.A. 54:34-1 et seq.source, with the beneficiary classes and rates set by N.J.S.A. 54:34-2source. The inheritance tax applies to transfers to certain categories of beneficiaries:

• Class A (exempt): Spouse, children, grandchildren, parents, and grandparents are fully exempt from the NJ inheritance tax
• Class C: Siblings and spouses/civil union partners of the decedent's children receive a $25,000 exemption, with rates of 11-16% on the excess
• Class D: All other beneficiaries (friends, business partners, non-relatives) pay 15-16% with no exemption on transfers over $500

Because the inheritance tax turns on the relationship of the ultimate beneficiary to the decedent, a disclaimer trust funded with assets that will ultimately pass to Class A beneficiaries (children, grandchildren) ordinarily falls outside the New Jersey inheritance tax. Where trust provisions can direct assets to Class C or D beneficiaries, however, the inheritance tax becomes a real factor and should be weighed in the disclaimer decision — one more reason the disclaimer amount is best set with counsel rather than by default.

Disclaimer Trusts Compared to Other Trust Structures

Understanding how a disclaimer trust compares to other common estate planning structures helps families make informed decisions:

• Disclaimer trust vs. credit shelter (bypass) trust: A credit shelter trust funds automatically at the first death, typically using a formula tied to the federal exemption amount. The funding amount is locked in by the trust terms, regardless of the circumstances at the time of death. A disclaimer trust provides the same tax benefits but gives the surviving spouse the choice of whether and how much to fund. The trade-off is that the disclaimer trust requires the surviving spouse to act within nine months, while the credit shelter trust operates automatically
• Disclaimer trust vs. portability: Portability (electing to transfer the deceased spouse's unused exemption to the surviving spouse via Form 706) is simpler than a disclaimer trust and requires no action by the surviving spouse beyond filing the estate tax return. However, portability does not capture future appreciation, does not provide creditor protection, cannot shelter assets from the GST tax, and can be lost if the surviving spouse remarries. A disclaimer trust provides all of these additional protections
• Disclaimer trust vs. SLAT: A spousal lifetime access trust (SLAT) is an irrevocable trust created during the couple's joint lifetime that removes assets from the taxable estate while providing the beneficiary spouse with access to trust distributions. Unlike a disclaimer trust, a SLAT requires a lifetime gift and an irrevocable commitment. A SLAT is a more aggressive planning tool; a disclaimer trust is more conservative and flexible

Practical Scenarios

Scenario 1: The Estate Is Well Below the Exemption

A couple has a combined estate of $4 million. The first spouse dies. The surviving spouse evaluates the estate and determines that there is no federal estate tax exposure. The surviving spouse disclaims nothing and inherits the entire estate outright. The disclaimer trust remains unfunded. The plan worked exactly as intended: the flexibility was available if needed, but the simplest outcome (outright inheritance) was the right choice.

Scenario 2: The Estate Has Grown Significantly

A couple has a combined estate of $22 million at the time the first spouse dies. The surviving spouse works with their attorney and financial advisor and determines that disclaiming approximately $13 million into the disclaimer trust will fully utilize the deceased spouse's federal exemption and protect that amount plus all future appreciation from inclusion in the surviving spouse's estate. The surviving spouse retains $9 million outright, which is more than sufficient for their needs. The disclaimer trust provides for the surviving spouse during their lifetime and can pass the remaining assets to the children outside the surviving spouse's taxable estate.

Scenario 3: Uncertainty About Future Tax Law

A couple creates their estate plan during a period of legislative uncertainty about the future of the federal estate tax exemption. Rather than locking in a formula that depends on a specific exemption amount, they choose a disclaimer trust. If the exemption remains high at the first death, the surviving spouse may disclaim little or nothing. If Congress reduces the exemption before the first death, the surviving spouse can disclaim the maximum amount to protect assets. The disclaimer trust gives the family flexibility to respond to legislative changes that cannot be predicted at the time the plan is drafted.

Frequently Asked Questions

Can the surviving spouse disclaim only part of an inherited asset?

Yes. Under IRC § 2518source, a disclaimer may apply to an undivided portion of an interest in property. For example, the surviving spouse could disclaim 60% of an inherited investment account and retain 40% outright. The disclaimed portion passes into the disclaimer trust. This partial disclaimer gives the surviving spouse precise control over how much goes into the trust and how much they retain. However, the disclaimer must cover a specific, identifiable portion of the property interest, not selected individual assets from a larger group.

What if the surviving spouse is incapacitated and cannot make the disclaimer decision?

If the surviving spouse lacks the capacity to make a disclaimer decision within nine months, their agent under a durable power of attorney may be able to make the disclaimer on their behalf, provided the power of attorney specifically authorizes the agent to make disclaimers. This is one of the reasons the Simon Law Group includes disclaimer authority in every durable power of attorney we draft. Without this authority, the nine-month deadline may pass, and the disclaimer opportunity is lost.

Does a disclaimer trust work for non-citizen spouses?

The unlimited marital deduction under IRC § 2056source is generally not available for transfers to a non-citizen spouse. In that situation a qualified domestic trust (QDOT) under IRC § 2056Asource is ordinarily used to defer estate tax until distributions are made from the trust. A disclaimer trust can be structured to work in conjunction with a QDOT, but the planning is more involved and calls for careful coordination across estate planning counsel and the family's immigration circumstances.

Can I change my mind after making a disclaimer?

No. A qualified disclaimer under both federal law (IRC § 2518source) and New Jersey law (N.J.S.A. 3B:9-1source) is irrevocable. Once the disclaimer is executed and delivered, it cannot be revoked or modified. The surviving spouse cannot later decide to take back the disclaimed property. This irrevocability is what makes the disclaimer effective for tax purposes, so the decision should be made with counsel and with full understanding of the consequences.

Contact Simon Law Group

A disclaimer trust is one of the more elegant tools in estate planning precisely because it commits to nothing today and preserves every option for the day it is actually needed. But it only works if the disclaimer provisions are drafted to operate cleanly under IRC § 2518source and N.J.S.A. 3B:9-1 et seq.source, and only if the surviving spouse knows to act inside the nine-month window. Simon Law Group helps New Jersey families decide whether that flexibility fits their situation, drafts the provisions so they function when the time comes, and stands ready to guide the surviving spouse through the disclaimer decision itself.

Frequently Asked Questions

What is a disclaimer trust?

A trust structure that gives the surviving spouse the ability to direct assets into a trust AFTER the first spouse's death, rather than during their joint lifetimes. The surviving spouse 'disclaims' (refuses) a portion of the inheritance within 9 months, and the disclaimed assets pass into a trust. This provides flexibility because the funding decision is made when the surviving spouse has full information about tax law, estate size, and their financial needs.

How long do I have to make a disclaimer?

Under both federal law (IRC § 2518) and NJ law (N.J.S.A. 3B:9-1 et seq.), a valid disclaimer must be made in writing within nine months of the date of death. The deadline is strict and cannot be extended. The disclaimant must not have accepted the interest or any of its benefits before disclaiming.

What is the advantage of a disclaimer trust over portability?

A disclaimer trust captures future appreciation outside the surviving spouse's estate (portability does not). It also provides creditor protection for trust assets, allows allocation of the GST tax exemption (which cannot be ported), and offers state tax planning benefits. Portability is simpler but a disclaimer trust provides more comprehensive protection.

Do I need a disclaimer trust if the exemption is $15 million?

For most families, the OBBBA-set $15M exemption for 2026 means federal estate tax is not a concern. However, a disclaimer trust can still provide creditor protection, GST planning, and protection against future legislative changes. It is most useful for families whose combined estate may approach or exceed $15M over time.

What happens if the surviving spouse does nothing within 9 months?

If no disclaimer is made within the 9-month deadline, the surviving spouse inherits everything outright. The disclaimer trust remains unfunded and has no effect. The opportunity to use the deceased spouse's exemption through the trust is lost (though portability may still be available if Form 706 is filed).
