California Trust Law: What Every Trust Holder Needs to Know

California has its own set of trust rules, and they don't follow the Uniform Trust Code that most other states use. If you have a trust in California, or if your trust holds California real estate, the rules here are specific, detailed, and carry real deadlines. Missing them can create serious problems for your family.

This guide covers what matters most to you as a trust holder or trustee in California. No legal jargon where we can avoid it, and plain explanations where we can't.

This guide applies to both revocable and irrevocable trusts in California, though certain requirements (especially notice deadlines) only kick in when a trust becomes irrevocable, typically after the trust creator passes away.

Where California trust law lives

California trust law is in Probate Code Division 9, sections 15000 through 19403. It was enacted in 1986, more than a decade before the Uniform Trust Code even existed. California's rules were actually so influential that the people who wrote the UTC used California's code as a model.

This matters because when you search online for trust guidance, most of what you find is based on UTC rules. California does things differently in several important areas, especially around notice requirements, contest deadlines, and accounting obligations.

What California trustees are required to do

If you're serving as trustee of a California trust (even if you're the person who created it), you have specific legal duties.

Act in the best interest of the beneficiaries. Section 16002 says you must manage the trust "solely in the interest of the beneficiaries." You can't use trust assets for your own benefit or make decisions that favor one beneficiary over another unless the trust document specifically allows it.

Invest carefully. California adopted the Prudent Investor Act (sections 16045 through 16054), which means you need to look at the trust's investments as a whole portfolio, not one investment at a time. You should diversify unless there's a good reason not to, and you need to consider things like the trust's purposes, the beneficiaries' needs, and general economic conditions. If you have professional investment experience, you're held to a higher standard than someone without that background.

Keep beneficiaries informed. Under section 16060, you have to keep beneficiaries "reasonably informed of the trust and its administration." This is a broad obligation. It means answering reasonable questions, not hiding information, and providing formal accountings (more on that below).

Keep good records. You need to track income, expenses, distributions, and assets. Keeping trust property separate from your personal property isn't optional. It's the law under section 16009.

TrustHelm tip: TrustHelm's dashboard organizes your trustee duties by state, tracks your deadlines, and keeps a complete record of trust assets and financial activity. If you're a California trustee, the platform flags your annual accounting deadline and tracks what needs to be included.

The annual accounting requirement

California is strict about this. Under section 16062(a), trustees must provide a formal accounting at least once a year to every beneficiary who is currently receiving distributions or is eligible to receive them. You also have to provide an accounting when the trust ends or when a new trustee takes over.

The accounting isn't just a summary. Section 16063 spells out what it has to include: all receipts and disbursements of principal and income, a list of trust assets and their values, trustee compensation, any agents you hired and what you paid them, and a notice that beneficiaries have the right to petition the court.

California doesn't set a specific calendar deadline like "within 90 days of the fiscal year end." The law says "at least annually," so best practice is to tie it to the trust's fiscal year and deliver the accounting within a reasonable time after each year ends.

One thing that catches people off guard: the trust creator cannot waive the trustee's duty to provide trust terms to beneficiaries. Section 16068 says any such waiver in the trust document is void. Even if the trust says "the trustee doesn't have to tell the beneficiaries anything," California law overrides that.

The 60-day notice and 120-day contest window

This is California's most distinctive requirement, and it's the one most often missed.

When a trust becomes irrevocable (usually when the trust creator dies), section 16061.7 requires the trustee to send a formal notice to every beneficiary and every legal heir within 60 days. The deadline is 60 days from the date the trust becomes irrevocable, or 60 days from the date you accept your role as trustee, whichever comes later.

The notice has to include specific information: the trust creator's name, the date the trust was signed, the trustee's name and contact information, and where the trust is being administered.

Here's the critical part. The notice must contain a boldface warning in at least 10-point type telling beneficiaries they have 120 days to contest the trust. If a beneficiary wants to challenge the trust, they have 120 days from the date they received the notice, or 60 days from the date they received a copy of the trust terms, whichever is later.

The trust creator cannot waive this notice requirement. Even if the trust document says "no notice is required," section 16061.7(i) makes that waiver void. The notice has to happen.

If you miss this 60-day window, you face personal liability as trustee, and the 120-day contest period doesn't start running. That means beneficiaries could potentially contest the trust for years.

How trustee compensation works in California

If the trust document specifies what the trustee gets paid, that's what controls. If the trust is silent on compensation, section 15681 says the trustee is entitled to "reasonable compensation under the circumstances."

California does not have a statutory fee schedule like New York does. There's no set percentage. Instead, courts look at factors from a case called Estate of Nazro: the trust's gross income, how well the trustee managed things, whether unusual skill was required, how much time the trustee spent, what's customary in the community, the risk involved, and how complex the work was.

For family trusts where a family member serves as trustee, compensation is often modest or waived entirely. Professional trustees (banks, trust companies) typically charge 0.5% to 1.5% of trust assets annually, depending on the trust's size and complexity.

Statute of limitations for trust claims

If a beneficiary believes the trustee did something wrong, they generally have 3 years to bring a claim after receiving an accounting that adequately discloses the issue (section 16460). If the accounting didn't adequately disclose the problem, or if no accounting was provided at all, the 3-year clock starts from the date the beneficiary discovered (or should have discovered) the issue.

The trust document cannot set an objection period shorter than 180 days (section 16461(d)).

This is why annual accountings matter so much. Each time you provide a thorough, complete accounting, you start a 3-year clock for claims related to that period. If you never account, the clock never starts.

California-specific rules that catch people off guard

Proposition 19 changed everything about inherited property taxes. Before February 2021, children could inherit a parent's home and keep the parent's low property tax assessment with no limit. Now, under Revenue and Tax Code section 63.2, the parent-child exclusion only applies if the child uses the property as their primary residence, and there's a $1 million cap on how much the assessed value can increase. If you're inheriting California real estate through a trust, this is a major financial consideration.

Community property stays community property in a trust. If a married couple puts community property into their trust, it remains community property during the marriage (Family Code section 761). This matters because community property gets a full stepped-up tax basis when one spouse dies, potentially saving the surviving spouse significant capital gains taxes. If the trust accidentally converts community property to separate property, that tax benefit disappears.

The Heggstad petition can save an unfunded trust. If the trust creator forgot to transfer an asset into the trust before dying, California has a unique remedy under section 850. A Heggstad petition lets beneficiaries ask the court to confirm that the asset belongs to the trust based on evidence of the creator's intent (like a schedule of assets attached to the trust document). This can avoid a full probate proceeding for the missed asset.

No-contest clauses are limited. Under sections 21310 through 21315, a no-contest clause in a California trust only applies to direct contests filed without probable cause. Beneficiaries can petition the court for a determination of whether their proposed action would trigger the no-contest clause before they actually file it. This is more protective of beneficiaries than most states.

TrustHelm tip: TrustHelm tracks whether your trust assets are properly funded. If you bought a new home or opened a new account after creating your trust, the platform reminds you to retitle it into the trust so your family doesn't need a Heggstad petition later.

The most common California trust mistakes

Not funding the trust. Section 15200 requires that a trust actually hold property to be valid. Creating a trust but never transferring your assets into it is the number one mistake. Your family ends up in probate anyway.

Missing the 60-day notice deadline. When the trust becomes irrevocable, the trustee has 60 days to notify all beneficiaries and heirs. Missing this deadline creates liability and leaves the contest window open indefinitely.

Forgetting to retitle property after refinancing. When you refinance your home, the lender often requires you to take the property out of the trust temporarily. After closing, you need to transfer it back. Many people forget, and the house ends up outside the trust when they pass away.

Ignoring Proposition 19. Families who assumed their children would inherit property with the parent's low tax assessment are discovering the rules changed dramatically in 2021. Planning around Proposition 19 is now essential for any California trust that includes real estate.

Skipping annual accountings. Every year you don't provide an accounting is a year where the 3-year statute of limitations doesn't start running on potential claims. This protects the trustee when done right, and exposes them when skipped.

Not filing Form 541. After the trust creator dies and the trust becomes irrevocable, the trust becomes a separate tax entity. The trustee must file a California Fiduciary Income Tax Return (Form 541) annually. Many successor trustees don't realize this obligation exists.

How California compares to other states

California is one of only about 14 states that have not adopted the Uniform Trust Code. Most online trust guidance assumes UTC rules, which don't fully apply here. A few key differences:

Accounting is mandatory, not optional. Many UTC states only require accounting when a beneficiary specifically asks for it. California requires it automatically, at least once a year.

The 60-day notice requirement is unique. Most states don't have anything as structured as California's section 16061.7 notice-and-contest framework. If you're reading general trust advice online, it probably won't mention this deadline.

Trusts default to revocable. In California, a trust is assumed to be revocable unless the document says otherwise. In some states like Texas and New York, the default is irrevocable. This matters if your trust document is ambiguous.

California is expensive for trusts. With a top state income tax rate of 13.3%, strict notice and accounting requirements, and a 90-year rule against perpetuities, California is not considered a favorable trust jurisdiction. That's why some families with large trusts move them to states like Nevada or South Dakota. If you're considering that, talk to your attorney first because the process has its own compliance requirements.

When to talk to an attorney

This guide gives you the foundation, but California trust law is complex enough that certain situations call for professional help. You should consult a California trust attorney if: you've just become a successor trustee and the trust creator has passed away, you need to send the section 16061.7 notice and want to make sure it's done correctly, you're dealing with real estate and Proposition 19 implications, a beneficiary is threatening to contest the trust, or you need to modify an irrevocable trust.
