California Dynasty Trust Lawyer 2026: Perpetual Wealth Transfer Under Probate Code § 21205

California dynasty trust lawyer helps families build perpetual wealth. Leverage the $13.61M GSTT exemption (2026), California’s perpetual trust law, and decanting. Free consultation.

“Key Takeaways”

  • California dynasty trusts are limited to 90 years. Under Probate Code § 21205, California follows the Uniform Statutory Rule Against Perpetuities (USRAP). A trust can last either 90 years after its creation or 21 years after the death of a “life in being” at the time of creation. This is not perpetual, but still allows multi‑generational wealth transfer.
  • The 2026 GSTT exemption is $15 million per person, permanently indexed. The One Big Beautiful Bill Act (OBBBA), signed in July 2025, repealed the sunset and set the lifetime exemption (and GSTT exemption) at $15 million, adjusted for inflation. There is no longer a “sunset cliff” dropping the exemption.
  • Dynasty trusts can be flexible through decanting and modification. Under Probate Code § 19530 (decanting) and § 15409 (modification), California trustees can adapt trusts to changing family needs, investment strategies, and tax laws—even within the 90‑year limit.
  • AB 565 (2026) introduces virtual representation, but does not eliminate court approval. Virtual representation under Probate Code § 15804 allows a parent to represent minor children and a guardian to represent a ward, streamlining consent. However, if the trust instrument does not grant independent modification power, a court petition is still required.
  • San Diego trust litigation is now at the Central Courthouse (1100 Union St). As of 2026, the Probate Division has moved from the Hall of Justice to the Central Courthouse. We handle dynasty trust disputes under Probate Local Rule 4.3.2 and file using Form PR‑160.

California Dynasty Trust Lawyer: The 2026 Guide to Multi‑Generational Wealth

Introduction: The $20 Million Estate That Could Have Lasted 90 Years

When Richard, a San Diego real estate developer, died in 2024, he left his three children a $20 million estate. His will split the assets equally, free of trust. Within one generation, the estate was reduced by 40%—state and federal estate taxes consumed nearly $8 million. By the time his grandchildren received their shares, the wealth had dwindled further. Richard’s dream of building a family legacy evaporated in just two generations.

Richard’s mistake was not using a dynasty trust. A properly drafted dynasty trust can shield assets from estate taxes for up to 90 years, providing for children, grandchildren, great‑grandchildren, and beyond—within California’s statutory limits.

At Leeran S. Barzilai, A Prof. Law Corp. , we help San Diego families build lasting legacies. This guide will walk you through how dynasty trusts work under California’s 90‑year rule, the 2026 tax landscape, and how to create a trust that adapts to future generations.

Part One: What Is a Dynasty Trust? The California Framework

The Core Concept

A dynasty trust is an irrevocable trust designed to hold wealth for multiple generations. It uses the generation‑skipping transfer tax (GSTT) exemption to shield assets from estate taxes each time the wealth passes to a new generation.

How It Works:

  • You transfer assets to an irrevocable trust during life or at death.
  • You allocate a portion of your GSTT exemption to the transfer.
  • The trust continues for your children, grandchildren, and future descendants for up to 90 years.
  • Distributions to beneficiaries are subject to income tax, but the trust principal is not subject to estate tax at each generation.

California’s 90‑Year Limit – Probate Code § 21205

Unlike “perpetual” dynasty trust states like South Dakota or Delaware, California limits the duration of trusts under the Uniform Statutory Rule Against Perpetuities (USRAP). Probate Code § 21205 provides:

“A nonvested property interest or a power of appointment is invalid unless, when the interest is created, it is certain to vest or terminate no later than 90 years after its creation.”

What This Means: A California dynasty trust cannot last forever. It must either:

  • Terminate no later than 90 years after its creation, or
  • Be based on a “life in being” (e.g., the settlor’s youngest descendant) plus 21 years.

We draft dynasty trusts to maximize the 90‑year period, ensuring that multiple generations benefit without violating the rule.

Part Two: The 2026 GSTT Landscape – $15 Million Exemption (Permanent)

The One Big Beautiful Bill Act (OBBBA)

The federal generation‑skipping transfer tax (GSTT) exemption for 2026 is $15 million per individual, permanently indexed for inflation. This follows the enactment of the One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, which repealed the prior sunset provisions.

Key Points:

  • The $15 million exemption applies to both the estate tax and the GSTT.
  • Married couples can effectively shield up to $30 million using portability.
  • There is no sunset—the higher exemption is permanent under current law.

How to Allocate GSTT Exemption

Under Internal Revenue Code § 2632, the GSTT exemption is automatically allocated to certain transfers unless you elect out. For dynasty trusts, we typically affirmatively allocate the exemption on a timely filed gift tax return (Form 709).

Example: You transfer $10 million to a dynasty trust in 2026. You allocate $10 million of your $15 million GSTT exemption. The trust is now fully exempt from GSTT. The remaining $5 million exemption can be used for other gifts.

Part Three: The Flexible Dynasty Trust – Decanting and Modification

Why Flexibility Matters

A dynasty trust must last up to 90 years. Family circumstances change; tax laws change; investment strategies evolve. A rigid trust that cannot adapt is a liability, not an asset.

Decanting – Probate Code § 19530

Under Probate Code § 19530, a trustee may decant an irrevocable trust—pour assets into a new trust with updated terms—if the trust instrument authorizes decanting. Decanting can:

  • Change distribution terms
  • Add spendthrift protections
  • Adjust to new tax laws
  • Move trust administration to a different jurisdiction

Strategic Note: We draft dynasty trusts with decanting power built in, giving future trustees flexibility without court approval.

Trust Modification – Probate Code § 15409

Even without decanting power, a trustee may petition the court to modify an irrevocable trust under Probate Code § 15409 for changed circumstances. This is more costly than decanting but provides a safety valve for trusts lacking decanting authority.

Part Four: Virtual Representation Under AB 565 – Streamlining Multi‑Generational Consent

The 2026 Game‑Changer

Effective January 1, 2026, AB 565 amends Probate Code § 15804 to allow virtual representation in trust proceedings. For a dynasty trust with dozens or hundreds of beneficiaries—including minors, unborn, and unknown—this is transformative.

How It Helps:

  • A parent may represent minor children.
  • A guardian may represent a ward.
  • A trustee may represent trust beneficiaries (if no conflict).
  • A holder of a power of appointment may represent potential appointees.

Important Limitation: Virtual representation does not eliminate the need for court approval when the trust instrument does not grant independent modification power. If you need to modify a dynasty trust under § 15409 (because the trust lacks decanting authority), you must still petition the court. Virtual representation streamlines the process by reducing the number of beneficiaries who must be individually noticed or consent, but it does not bypass the statutory requirement for judicial oversight when required.

Practical Use: When you need to decant or modify a dynasty trust, virtual representation can eliminate the need to track down and obtain consent from every remote beneficiary. We prepare declarations establishing virtual representation and either file them with the court (if a petition is required) or keep them as part of the trust records.

Part Five: Tax Considerations – Income Tax, Capital Gains, and Basis

Grantor Trust Status

Most dynasty trusts are drafted as grantor trusts for income tax purposes. This means the grantor pays the income tax on trust earnings, allowing the trust assets to grow free of that tax drag. Under current law, a grantor trust is not treated as a completed gift for estate tax purposes, which can create complexities; we carefully structure to balance income tax benefits with GSTT allocation.

Capital Gains and Basis

When the trust sells assets, capital gains tax is due. Unlike estate tax, capital gains are not avoided by the dynasty trust. However, if the trust is a grantor trust, the grantor pays the tax—effectively making a tax‑free gift to the trust.

Strategic Note: We often combine a dynasty trust with a family limited partnership or LLC to allow valuation discounts, further leveraging the GSTT exemption.

Part Six: San Diego Superior Court – New Central Courthouse Location

Venue: Central Courthouse, 1100 Union St

As of 2026, the San Diego Superior Court Probate Division has moved from the Hall of Justice to the Central Courthouse at 1100 Union Street, San Diego, CA 92101. All trust‑related matters, including dynasty trust disputes, are now heard here.

Local Procedures

  • E‑filing: Under Probate Local Rule 4.3.2, all trust‑related filings must be e‑filed.
  • Case Cover Sheet: We use Probate Case Cover Sheet (Form PR‑160) to ensure the case is properly designated for the Probate Division.
  • Proof of Service: Form SDSC PR‑001.

At Leeran S. Barzilai, A Prof. Law Corp. , we have extensive experience handling dynasty trust matters in San Diego courts, from routine accountings to complex GSTT allocation disputes—all at the new Central Courthouse.

Part Seven: Client Document Collection Checklist

If you are considering a dynasty trust, gather:

  • List of assets (real estate, investments, business interests, cash)
  • Current estate planning documents (wills, existing trusts)
  • Gift tax returns (to track prior GSTT allocation)
  • Names and dates of birth of children, grandchildren, and future descendants
  • Financial statements (balance sheet, cash flow)
  • Information about any existing trusts that may be merged or decanted

Frequently Asked Questions

What is a California dynasty trust?

A dynasty trust is an irrevocable trust designed to pass wealth to multiple generations without incurring estate taxes at each generation. In California, it is limited to 90 years under Probate Code § 21205, but can still provide for children, grandchildren, and great‑grandchildren.

What is the generation‑skipping transfer tax (GSTT)?

The GSTT is a federal tax imposed on transfers to beneficiaries who are two or more generations below the transferor. The 2026 exemption is $15 million per person, permanently indexed under the One Big Beautiful Bill Act.

Can a California dynasty trust last forever?

No. California follows the Uniform Statutory Rule Against Perpetuities, which limits nonvested interests to 90 years (or 21 years after a life in being). We draft trusts to maximize this period, but they are not perpetual.

How do I allocate my GSTT exemption to a dynasty trust?

You allocate the exemption by filing a gift tax return (Form 709) for the year of the transfer. We prepare and file these returns to ensure proper allocation.

Can a dynasty trust be changed after it is created?

Yes. California trusts can be decanted under Probate Code § 19530 or modified under § 15409. We build decanting power into dynasty trusts to give future trustees flexibility without court involvement. If decanting is not available, a court petition may be required.

How does virtual representation (AB 565) help dynasty trusts?

AB 565 (effective January 1, 2026) allows a parent to represent minor children, a guardian to represent a ward, and a trustee to represent beneficiaries (absent conflicts). This streamlines obtaining consent for modifications or decanting, but does not eliminate court approval when the trust lacks independent modification power.

Where are dynasty trust disputes heard in San Diego?

They are heard in the Probate Division at the Central Courthouse, 1100 Union Street, San Diego, CA 92101. We file all documents using e‑filing under Probate Local Rule 4.3.2 and Form PR‑160.

Can I use a dynasty trust to hold my business or real estate?

Yes. A dynasty trust can own LLC interests, real estate, and other business assets. We often combine dynasty trusts with family limited partnerships to obtain valuation discounts.

What are the income tax consequences of a dynasty trust?

Most dynasty trusts are drafted as grantor trusts, meaning the grantor pays the income tax. This allows the trust assets to grow free of that tax burden, effectively making additional tax‑free gifts to the trust.

Do you offer services in other languages?

Yes. We provide dynasty trust planning services in Spanish, Hebrew, and Chinese to serve San Diego’s diverse community. Contact us to schedule a consultation in your preferred language.
