A marital trust, also called a marital deduction trust, is a cornerstone estate planning tool that helps married couples secure financial support for the surviving spouse and preserve wealth for future generations. This guide will help readers understand what a marital trust is, how it operates, why it matters, and how LegacyBridge’s wealth management expertise can help clients leverage this strategy for lasting family security.

Understanding Marital Trusts

A marital trust is a legal entity established by one spouse, transferring assets into the trust so that the surviving spouse receives financial benefits after the trust creator’s death. It is irrevocable, meaning the terms cannot be changed after creation. The primary purpose is to provide income and, sometimes, principal payments to the surviving spouse while ultimately directing assets to children, grandchildren, or other designated beneficiaries after both spouses have passed.

Key Characteristics

  • Provides structured income and support for the surviving spouse.

  • Preserves and protects assets to benefit children and other heirs after both spouses have died.

  • Can shield family assets from probate, creditors, and sometimes taxes.

  • Utilizes the unlimited marital deduction, allowing assets to transfer tax-free to the surviving spouse at the time of the first spouse’s death.

How Does a Marital Trust Work?

A marital trust goes into effect when the first spouse dies. Here’s an overview of the process.

  • The trustor (“grantor” or “settlor”) establishes the trust, naming the surviving spouse as the primary beneficiary and other heirs as eventual beneficiaries.

  • Upon the death of the grantor, specified assets are moved into the trust.

  • The surviving spouse is entitled to all income generated by these assets and, depending on the trust’s terms, may receive principal as needed.

  • When the second spouse dies, any remaining assets are then transferred to the named heirs (children, grandchildren, charities, etc.).

Example of Marital Trust Structure

A couple creates a marital trust. When one spouse passes, their investments and real estate enter the trust. The surviving spouse receives quarterly income. Afterward, the family home and remaining investments go to their children, ensuring both a surviving spouse’s welfare and a clear legacy path for future generations.

Types of Marital Trusts

There are several structures within marital trusts, each with distinct benefits to address various family needs.

Common Types:

  • QTIP Trust (Qualified Terminable Interest Property): Gives the surviving spouse income for life but restricts their ability to redirect the trust principal, protecting children from previous marriages or blended family scenarios.

  • General Power of Appointment Trust: Grants the surviving spouse broader access to trust assets, including the ability to direct them upon their own death.

  • Estate Trust: Income and principal may be available to the surviving spouse, with full disposition to heirs after their death.

Who Should Consider a Marital Trust?

Marital trusts are especially effective for:

  • Blended families, where asset distribution among biological and stepchildren needs clear direction.

  • High net worth couples seeking to minimize estate taxes and probate.

  • Spouses who want to ensure the surviving partner is protected but that specific assets eventually reach chosen heirs.

  • Anyone whose goals include preserving wealth across multiple generations.

Benefits of a Marital Trust

  • Tax Savings: Leverages the unlimited marital deduction, delaying estate taxes until the death of the second spouse.

  • Asset Protection: Shields inherited assets from creditors and legal claims during the surviving spouse’s lifetime.

  • Clear Asset Distribution: Ensures that remaining assets go directly to chosen beneficiaries after both spouses’ deaths.
  • Probate Avoidance: Trust assets generally pass outside the often lengthy and expensive probate process.

Limitations and Considerations

  • Marital trusts are irrevocable, making their terms difficult—sometimes impossible—to change after establishment.

  • When the second spouse passes, assets in the trust are generally included in their estate, potentially triggering estate taxes at that point.

  • Careful drafting is required to balance the interests of the surviving spouse and other beneficiaries, especially in blended families.

LegacyBridge works closely with clients and their legal advisors to ensure marital trusts are structured for maximum family benefit and aligned with broader wealth management and legacy goals.

Frequently Asked Questions About Marital Trusts

1. What are the biggest advantages of a marital trust for families?

A marital trust provides tax benefits by enabling the unlimited marital deduction, delaying or eliminating estate taxes until the death of the second spouse. It provides ongoing income and occasionally principal support for the surviving spouse while protecting the original family wealth for children and future generations. The trust design can prevent assets from being mismanaged or claimed by creditors, and it offers a clear path for inheritance, making wealth transfer predictable and efficient. Additionally, marital trusts help families avoid probate, which can save time, legal fees, and maintain privacy in the estate process.

2. How does a QTIP trust differ from a basic marital trust?

A QTIP (Qualified Terminable Interest Property) trust is a type of marital trust that provides income to the surviving spouse for life but allows the original trust creator to specify how the remaining assets are to be distributed after that spouse dies. This means the surviving spouse cannot redirect the principal to new beneficiaries or a new spouse, protecting interests of children from previous marriages or blended family situations. A QTIP trust is ideal for those who want to provide for a spouse while ensuring that ultimate asset control remains with the original family line. In contrast, a general power of appointment marital trust gives the surviving spouse much greater flexibility with the assets.

3. Can establishing a marital trust help avoid probate?

Yes, assets held in a marital trust generally avoid probate upon the death of both spouses. Probate can be time-consuming, expensive, and public. By using a marital trust, families can pass assets privately and efficiently to surviving spouses and then to their intended next-generation beneficiaries. This is one of the defining efficiency and privacy benefits of marital trusts as part of a LegacyBridge wealth management strategy. However, proper titling and funding of the trust are critical to fully realizing these benefits. LegacyBridge helps clients ensure both initial setup and ongoing management support probate avoidance and maximize value for heirs.
