Why a Testamentary Trust Under a Last Will & Testament Probably is NOT Your Best Option

March 18, 2025 by Autumn Bryant

When planning your estate, you'll likely encounter the concept of a testamentary trust—a trust created through your Last Will and Testament that only takes effect after your death. While testamentary trusts serve specific purposes, they come with significant limitations that many people overlook. Here's why a testamentary trust might not be the optimal solution for your estate planning needs.

When planning your estate, you'll likely encounter the concept of a testamentary trust—a trust created through your Last Will and Testament that only takes effect after your death. While testamentary trusts serve specific purposes, they come with significant limitations that many people overlook. Here's why a testamentary trust might not be the optimal solution for your estate planning needs.

It Does Not Avoid Probate

Perhaps the biggest misconception about testamentary trusts is that they help avoid probate. This is not true. Since a testamentary trust is established through your Will, the entire Will must go through probate before the trust can even be created.

Probate is the court-supervised process of authenticating your Will, paying debts and taxes, and distributing assets. This process can be:

  • Time-consuming: Typically lasting 6-12 months, but potentially years in complex cases
  • Expensive: Court costs, attorney fees, executor commissions, and other expenses can consume 3-7% of your estate's value
  • Public: Probate proceedings create public records, exposing your financial affairs and beneficiaries to public scrutiny
  • Subject to challenges: The public nature of probate makes it easier for disgruntled relatives to contest your Will

Since your testamentary trust doesn't exist until after probate concludes, all assets destined for the trust must first pass through this process.

Jointly Owned Assets and Beneficiary Designations Bypass Your Will Entirely

Another critical limitation is that testamentary trusts only control assets that pass through your Will. Many valuable assets may bypass your Will completely:

  • Jointly owned property with right of survivorship automatically transfers to the surviving owner(s)
  • Life insurance policies pass directly to named beneficiaries
  • Retirement accounts (401(k)s, IRAs) go to designated beneficiaries
  • Payable-on-death accounts transfer immediately to named beneficiaries
  • Transfer-on-death deeds for real estate pass property outside probate

This means that regardless of what your Will specifies, these assets will never become part of your testamentary trust. This can inadvertently lead to uneven distributions among beneficiaries or completely undermine your estate planning goals.

Other Significant Drawbacks

Besides failing to avoid probate and lacking control over non-probate assets, testamentary trusts have additional limitations:

  • Court oversight: Unlike living trusts, testamentary trusts often remain under court supervision, requiring regular accountings and potentially court approval for distributions
  • Inflexibility: Once established through probate, testamentary trusts can be difficult and expensive to modify if circumstances change
  • Disability Planning: With all Will-based plan, there is a lack of disability planning for you and no guidance regarding what your intent is regarding a long-term disability situation
  • No immediate access for beneficiaries: Your loved ones must wait until probate concludes before receiving any benefits

Better Alternatives to Consider

For most estate planning goals, revocable living trusts offer significant advantages:

  • They avoid probate entirely
  • Assets can be transferred into the trust during your lifetime
  • They provide immediate management of assets if you become incapacitated
  • They offer greater privacy protection
  • They can be amended as needed during your lifetime

Conclusion

Testamentary trusts often fall short of meeting many people's primary objectives. Understanding that they don't avoid probate and don't control jointly owned or beneficiary-designated assets is crucial when determining the right approach for your estate plan.
