Trust Administration in Hidden Hills

Trust Administration in Hidden Hills

Serving as successor trustee of a Hidden Hills estate is a significant undertaking. These are complex estates with multiple properties, business interests, entertainment industry assets, intellectual property, investment portfolios, and beneficiaries who have resources to pursue disputes if they feel the administration is going wrong. The stakes of getting it wrong are high. Personal liability for a trustee who missteps in a Hidden Hills estate can be financially devastating.

I am an estate planning attorney serving Hidden Hills and the surrounding area. I do this work over Zoom or phone, and a mobile notary comes to you for the signing. Hidden Hills is in Los Angeles County, and trust disputes go to the LA County Superior Court. I keep trustees out of that courthouse. For the planning side, see the Hidden Hills estate planning page.

The 60-day notice that cannot be missed

Cal. Prob. Code §16061.7 requires notice to every beneficiary and statutory heir within 60 days of the settlor’s death. In Hidden Hills estates with complex family situations, prior marriages, children from different relationships, and beneficiaries in different states, identifying every required notice recipient correctly matters. The notice starts a 120-day contest window. If it is not sent, that shortened period never begins, so the general limitation rules apply instead and a beneficiary may be able to challenge the trust after distribution is complete. I make sure the notice is prepared correctly and sent to everyone who is required to receive it.

1. Within 60 days of the settlor’s death, send the Prob. Code § 16061.7 notice to every beneficiary and statutory heir.
2. The notice starts a 120-day contest window. If it isn’t sent, the window never begins.
3. File the change in ownership statement with the county recorder or assessor within 150 days after the date of death (Rev. & Tax. Code § 480(b)).
4. Keep beneficiaries reasonably informed throughout the administration (Prob. Code § 16060).
5. Account at least annually, and again on a change of trustee or termination of the trust (Prob. Code § 16062).
6. Document each decision about business interests, royalty streams and other major assets as you make it.

Managing entertainment and business assets during administration

A Hidden Hills estate may include an interest in a production company, royalty rights from intellectual property, or other assets that require active management decisions during administration. The trustee must make those decisions prudently, document them carefully, and avoid any self-dealing or favoritism. At Hidden Hills estate values, beneficiaries have the financial incentive to pursue the trustee personally if they believe decisions were made improperly. I help trustees understand what they can and cannot do, when they need court approval, and how to document every significant decision. This connects to high-net-worth estate planning for ongoing structural questions. For assets outside the trust, see probate.

The ongoing duties that protect the trustee, and the beneficiaries

Beyond the initial notice, Cal. Prob. Code §16060 requires the trustee to keep beneficiaries reasonably informed of the trust and its administration on an ongoing basis, and Cal. Prob. Code §16062 requires the trustee to account to beneficiaries at least annually, and again on a change of trustee or termination of the trust. For a Hidden Hills trust holding production company interests, real estate, and investment accounts, the accounting has to reflect all of it accurately, with supporting documentation the trustee can produce if questioned. A trustee who administers the trust properly under §16060 and §16062 builds a paper trail that protects against exactly the kind of challenge Cal. Prob. Code §15642 authorizes: a beneficiary petition to remove a trustee for breach of trust. Consistent, documented compliance with the informing and accounting duties is the best defense against a §15642 petition ever succeeding.

What administration replaces: the probate schedule as a yardstick

A trust administration has no statutory fee schedule and no court order approving fees. If the trust doesn’t set the trustee’s pay, the trustee is entitled to reasonable compensation under the circumstances (Prob. Code § 15681). That’s a flexible standard, so it helps to know the number the probate schedule would have produced for the same asset.

On the Zillow Home Value Index for August 2026, the typical Hidden Hills home is worth $5,134,415. The schedule in §§ 10800 and 10810 would allow $64,344 to the executor and the same to the attorney, or $128,688 together.

Slice of the estate	Rate	Fee for each of the executor and the attorney
First $100,000	4%	$4,000
Next $100,000	3%	$3,000
Next $800,000	2%	$16,000
Remaining $4,134,415	1%	$41,344
Total, each		$64,344

These figures assume an estate of only the typical home, figured on gross value with no deduction for a mortgage (§ 10810(b)). A trustee isn’t bound by them. The yardstick still helps: a trustee who bills far above it should have a reason written down. See trustee compensation in California for how the reasonableness standard works.

The 150-day county filing after a death, and what it does to a Hidden Hills tax bill

When the settlor of a trust dies, the trustee files a change in ownership statement with the county recorder or assessor within 150 days after the date of death (Rev. & Tax. Code § 480(b)). For a Hidden Hills home that’s the Los Angeles County recorder or assessor. If the assessor mails a written request and the statement isn’t filed within 90 days, the penalty is the greater of $100 or 10% of the taxes on the new base year value, capped at $5,000 for a home with the homeowners’ exemption and $20,000 without it, when the failure isn’t willful (§ 480(c)).

The filing decides the tax bill. A child who moves into the parent’s home within one year and files for the homeowners’ exemption within a year can claim the exclusion under § 63.2. The taxable value stays at the parent’s, plus market value above the parent’s taxable value plus $1,044,586 (the cap for transfers from February 16, 2025 to February 15, 2027). This table uses a parent taxable value of $1,800,000, which is my example, for illustration only, and not a Los Angeles County figure or a prediction.

Scenario	Parent’s taxable value plus the cap	Value added	New taxable value
Child moves in, home worth $5,134,415	$2,844,586	$2,289,829	$4,089,829
Home isn’t the child’s principal residence	Exclusion doesn’t apply	Full reassessment	$5,134,415

The Proposition 19 calculator and the guide to filing the exclusion take it from there.

Selling or holding the house inside the gate

The Hidden Hills Community Association governs the whole community from its office at 24549 Long Valley Rd. Before a trustee lists the house or distributes it to a beneficiary, ask the association for its governing documents and any approval or transfer steps. I don’t assume what they say.

A buyer’s title company will ask for proof that the trustee can sign. A certification of trust does that without handing over the trust: the trustee presents it in place of the trust instrument, it can confirm the trustee’s powers and the legal description, and it doesn’t have to include the dispositive terms (Prob. Code § 18100.5). A signed certification can be recorded with the county recorder. Three gatehouses control access to the community, so plan appraiser, broker, and inspector access with the association ahead of time. Certification of trust in California explains what goes in it.

Questions Hidden Hills clients ask

The estate includes production company interests. How do I manage those as trustee?

The trustee steps into the settlor’s ownership position in the company. You have whatever rights the ownership interest carries. Major decisions about the company may require coordination with other owners and may have implications for the company’s operations. Business counsel familiar with entertainment company governance is important alongside the trust attorney.

There are horses on the property. Who is responsible for them immediately?

The trustee has immediate authority and responsibility for trust assets, including horses. Decisions about their care cannot wait for probate proceedings. Document all care decisions and expenses from day one. If the horses are a business asset, additional considerations apply.

A beneficiary is threatening to challenge the trust. What do I do?

Call an attorney before making any distributions and before responding to threats. Threats of challenge do not by themselves stop administration, but they need to be taken seriously and handled correctly. Making the wrong distribution in response to a threat can create problems. Making a wrong distribution that triggers the actual challenge is worse.

How often do I actually have to account to the beneficiaries, and what happens if I do not?

Under §16062, an accounting is required at least annually, and also when the trust changes trustees or terminates. A trustee who fails to account or provide information under §16060 gives beneficiaries grounds to petition for removal under §15642, and can be held personally liable for losses the failure caused.

Can a beneficiary actually get me removed as trustee, and on what grounds?

Yes. Under §15642, a beneficiary can petition the court to remove a trustee for breach of trust, including failure to account, self-dealing, or mismanagement of trust assets. Documented, prudent administration under §16060 and §16062 is the trustee’s strongest protection against such a petition succeeding.

How much can the trustee charge on a $5 million estate?

If the trust doesn’t set the compensation, the trustee is entitled to reasonable compensation under the circumstances (Prob. Code § 15681). The probate fee schedule doesn’t govern a trust. On a $5,134,415 home, though, it would allow $64,344 to each of the executor and the attorney, which makes a useful comparison point.

How long after the death do we have to tell the county assessor?

The trustee files a change in ownership statement within 150 days after the date of death (Rev. & Tax. Code § 480(b)). Missing it after the assessor’s written request can add a penalty. If a child wants the Proposition 19 exclusion for a parent’s home, a separate claim is required under § 63.2.

Will the title company make me hand over the whole trust?

Not if you give it a certification of trust. Prob. Code § 18100.5 lets the trustee present a certification in place of the trust instrument, and it doesn’t have to include the terms that say who gets what. All currently acting trustees sign it.
