What Is a Spousal Lifetime Access Trust (SLAT) and How Does It Work in California?

Posted by Mark Ruiz | May 02, 2026 | 0 Comments

Over the years, I have had clients in California who are looking for more advanced estate planning strategies to reduce potential estate tax exposure while still maintaining some level of access to their assets during their lifetime. One strategy that often comes up in these discussions is the Spousal Lifetime Access Trust, commonly referred to as a SLAT. While this type of trust can be an effective tool in the right situation, it is important to understand how it works and whether it fits within your overall estate plan.

UNDERSTANDING A SLAT IN SIMPLE TERMS

A SLAT is an irrevocable trust created by one spouse for the benefit of the other spouse. In many cases, the idea is to transfer assets out of the taxable estate of the donor spouse while still allowing indirect access to those assets through the beneficiary spouse.

In California, SLATs are often used as part of broader estate tax planning strategies for high net worth families.

HOW A SLAT WORKS

In a typical SLAT arrangement, one spouse transfers assets into an irrevocable trust. The other spouse is named as a beneficiary of that trust. The trustee of the SLAT can then make distributions to the beneficiary spouse for health, education, maintenance, and support depending on how the trust is drafted.

This structure allows the couple to potentially benefit from the trust assets while still removing those assets from the taxable estate of the spouse who created the trust.

KEY BENEFITS OF A SLAT

There are several reasons why SLATs are used in California estate planning:

  • Potential reduction in federal estate tax exposure
  • Ability to shift appreciating assets out of the taxable estate
  • Indirect access to trust assets through the beneficiary spouse
  • Flexibility in managing long term wealth transfer strategies

However, these benefits must be carefully weighed against the limitations and risks involved.

IMPORTANT RISKS AND LIMITATIONS

While SLATs can be powerful, they are not without risk. One of the most significant considerations is what happens if the spouses later divorce or if the beneficiary spouse passes away unexpectedly.

Additional considerations include:

  • Irrevocable nature of the trust, meaning it cannot easily be undone
  • Loss of direct control over transferred assets
  • Potential gift tax implications when funding the trust
  • Complexity in drafting and administration

Because of these issues, SLATs require careful coordination with an experienced estate planning attorney.

SLATS IN CALIFORNIA COMMUNITY PROPERTY CONTEXT

California's community property laws add an additional layer of complexity. When community property is used to fund a SLAT, careful planning is required to properly characterize and transfer assets.

Improper structuring can lead to unintended tax consequences or disputes regarding ownership of trust assets.

FINAL THOUGHTS

A Spousal Lifetime Access Trust can be a valuable estate planning tool for certain California families, particularly those with significant assets or anticipated estate tax exposure. However, it is not appropriate for everyone and must be carefully structured to avoid unintended consequences.

If you are considering advanced estate planning strategies, it is important to evaluate how a SLAT fits into your overall goals, your family structure, and California property laws.
