What is the role of a trustee in a generation skipping trust

I recently had a client, Emily, come to me in a complete panic. Her father had passed away six months earlier, and she’d recently discovered his codicil to his trust was deemed invalid because it wasn’t properly witnessed and filed. The result? A trust designed to benefit her grandchildren now faced significant tax implications, costing her family over $250,000 in unexpected estate taxes. This scenario, unfortunately, is more common than you might think, and it highlights the critical importance of a knowledgeable trustee.

What Responsibilities Does a Trustee Have?

As an estate planning attorney and CPA with over 35 years of experience, I often explain to clients that a trustee’s job is far more complex than simply holding assets. It’s a fiduciary duty, meaning the trustee must act solely in the best interests of the beneficiaries – in this case, the grandchildren – and with the utmost care and diligence. Beyond the basic administration of the trust, a truly effective trustee proactively navigates a minefield of potential pitfalls. This includes understanding distribution guidelines, managing investments, and staying current with ever-changing tax laws.

How Does a CPA Benefit the Trust?

That’s where my CPA background comes in. Many trustees, while well-intentioned, lack the financial expertise to optimize the trust for tax efficiency. The power of a “step-up in basis” is frequently lost on those unfamiliar with capital gains taxes and the nuances of valuation. For example, if the trust owns a successful business, accurately valuing it at the time of transfer to the grandchildren is crucial. Failing to do so can lead to inflated tax liabilities when those assets are eventually sold. I’ve personally saved clients tens of thousands of dollars by ensuring proper valuation methods are used, leveraging my expertise in both tax and estate planning.

What About the 90-Year Rule and Trust Duration?

Another frequent concern is the duration of the trust itself. Unlike ‘dynasty friendly’ states like South Dakota, California is bound by the Uniform Statutory Rule Against Perpetuities (USRAP), which generally limits the trust’s lifespan to 90 years unless specific savings clauses are used. A trustee needs to be aware of this limitation and incorporate appropriate language to maximize the trust’s longevity, if that is the settlor’s intent. Otherwise, the trust could terminate prematurely, forcing an unintended distribution to the beneficiaries while they may not be financially prepared.

What Happens to Real Estate Held in the Trust?

Real estate within a GST trust presents unique challenges. Under Prop 19, transferring a home to grandchildren via a GST Trust almost always triggers a property tax reassessment to current market value, as the ‘grandparent-grandchild’ exclusion is severely restricted compared to the old Prop 58 rules. However, if the property needs to be quickly transferred to the trust after the settlor’s death, and is valued up to $750,000, a ‘Petition for Succession’ under AB 2016 (Probate Code § 13151) may be used. Remember, this is a “Petition” (Judge’s Order), NOT an “Affidavit,” and requires specific court approval.

What if the Settlor Has Business Interests?

If the trust holds business interests, especially in LLCs, compliance with federal regulations is paramount. While domestic U.S. LLCs held in the trust are exempt from BOI reporting as of March 2025, trustees managing foreign-registered entities must still file updates with FinCEN within 30 days to avoid federal fines. A proactive trustee understands these requirements and ensures the trust remains in good standing.

Don’t Forget Digital Assets!

Finally, with the increasing prevalence of digital assets, trustees must address the issue of access and control. Without specific RUFADAA language (Probate Code § 870) in the GST Trust, service providers can legally block your trustee from accessing crypto wallets or cloud accounts intended for future generations. This can render a significant portion of the trust assets inaccessible, defeating the entire purpose of the trust.

What separates a successful California trust distribution from a costly battle over interpretation and accounting?

Success in trust administration depends on more than just the document; it requires active management of assets, precise accounting to beneficiaries, and careful navigation of tax rules. Whether dealing with a blended family or complex real estate, understanding the mechanics of trust law is the only way to ensure the grantor’s wishes survive scrutiny.

To close a trust administration smoothly, the trustee must complete the steps of trust settlement, ensure no pending beneficiary claims exist, and distribute assets according to the revocable living trust.

Ultimately, the success of a trust depends on the details—proper funding, clear terms, and a trustee willing to follow the rules. By anticipating friction points and documenting every step of the administration, fiduciaries can protect the estate and themselves from liability.

Verified Authority on California Generation-Skipping Trust (GST) Administration

• GST Tax Exemption (OBBBA): IRS Estate & GST Tax Guidelines
  Reflects the OBBBA update effective January 1, 2026, which sets the GST Tax Exemption at $15 million per person. Proper allocation of this exemption is the only way to shield trust assets from the flat 40% tax on distributions to grandchildren.
• Trust Duration Limits (USRAP): California Probate Code § 21205 (90-Year Rule)
  California follows the Uniform Statutory Rule Against Perpetuities. This statute generally limits a Generation-Skipping Trust’s validity to 90 years, preventing “forever” trusts common in other jurisdictions.
• Property Tax Reassessment (Prop 19): California State Board of Equalization (Prop 19)
  Critical for GST planning. Prop 19 severely limits the “grandparent-grandchild” exclusion, meaning most real estate transfers to grandchildren will trigger a property tax increase to current market value.
• Primary Residence Succession (AB 2016): California Probate Code § 13151 (Petition for Succession)
  If a home intended for the GST trust was accidentally left out, this statute (effective April 1, 2025) allows a “Petition for Succession” for residences valued up to $750,000, avoiding a full probate.
• Digital Legacy (RUFADAA): California Probate Code § 870 (RUFADAA)
  The authoritative statute for digital assets. Without specific RUFADAA provisions in the trust, multi-generational access to cryptocurrency and digital files can be legally denied by custodians.
• Business Compliance (FinCEN): FinCEN – Beneficial Ownership Information (BOI)
  As of March 2025, domestic U.S. LLCs are exempt from mandatory BOI reporting. However, trustees managing foreign-registered entities must still comply with strict reporting windows to avoid penalties of $500/day.
