Agoura Hills Estate Planning: When the Documents You Signed Stop Matching Your Life

Agoura Hills is in Los Angeles County, and a good share of the trusts I review for clients here were signed a decade or more ago: sound documents at the time, drafted for a family, a property list, and a set of laws that have since moved on. I’m Eric Ridley, an estate planning attorney serving Ventura, Santa Barbara, and Los Angeles counties. Most of the calls I get from Agoura Hills aren’t from people who never planned. They’re from people whose plan went quiet years ago and nobody told them it needed another look.

A trust doesn’t expire, but it does go stale. Named trustees move away or pass on. A house gets bought or sold. A marriage ends or begins. And twice in the last two years, California changed the underlying law in ways that quietly invalidated assumptions built into earlier plans. None of that arrives as a letter. It sits until someone dies or loses capacity, and the family finds the plan assumed a version of the world that no longer exists.

No-cost 30-minute call, by phone or video. No pitch, just straight answers about whether your plan still fits.

What actually happens to a plan that “went stale”

Nobody drafts a bad plan on purpose. A stale plan was a good plan once: the right trustee for the family you had then, the tax rules of the year it was signed, the assets you owned at the time. What makes it dangerous is the silence afterward. The document sits in a drawer looking exactly as valid as the day it was signed, until someone tries to use it and discovers the trustee named on page four died years ago, or the house it was supposed to cover was refinanced and never retitled back into the trust.

Seven moments that should send you back to your attorney

Most people don’t revisit an estate plan on a schedule; they revisit it, if at all, when something happens to remind them. These events should trigger a review whether or not they happen to:

A move to or from California. Community property rules and trust situs change at the border. A will drafted for another state’s law doesn’t automatically translate.
A marriage or a divorce. A former spouse named as trustee, agent, or beneficiary doesn’t disappear from the document just because the marriage ended. Some designations for an ex-spouse are revoked by statute and some aren’t, depending on how the document is written.
A death among the people you named. Every trust and set of incapacity documents names successor trustees, executors, and agents in order. When one dies, the document doesn’t reorder itself.
A birth. A new child or grandchild is rarely covered by a plan drafted before they existed, and an outdated guardian nomination is often the piece nobody thinks to fix.
A new property or business. An asset acquired after the trust was signed has to be titled into it on purpose. It is the single most common reason a family with a trust still ends up in probate.
A child reaching adulthood. At 18, a parent loses automatic legal authority to make medical or financial decisions for that child. Without a health care directive and a power of attorney from the new adult, a parent facing a hospital’s questions can be told, correctly, that they have no legal standing to get answers.
Changes in the law itself. Nothing in your life has to change for your plan’s assumptions to become wrong. Two recent examples make the point concretely.

Proposition 19 replaced the exclusion your trust may still assume

Before 2021, a parent could leave a child a home, a rental, or a vacation property, and the child kept the parent’s old, much lower property tax assessment, on any property, of any value. Proposition 19 replaced that rule. A lot of Agoura Hills trusts predate 2021, and any of them drafted with the old rule in mind is planning around an exclusion that no longer works the way it used to.

The parent-child exclusion now applies only if the home was the parent’s principal residence and the child moves in and makes it their own principal residence, filing for the homeowners’ exemption to prove it. Even then the protection isn’t unlimited: it covers the old assessed value plus an amount adjusted every two years, currently $1,044,586 for transfers occurring February 16, 2025 through February 15, 2027. Market value above that combined figure gets added to the new assessed value. A rental, a second home, or a property a child doesn’t move into gets reassessed to full market value, with no exclusion at all, exactly what a trust signed in 2015 or 2018 had no way to anticipate.

The Medi-Cal asset test came back on January 1, 2026

California eliminated the Medi-Cal asset test in 2024, and for about a year and a half, planning advice, some of it correct at the time, said assets no longer mattered for long-term care eligibility. That advice expired. Under AB 116 (2025) § 59, the asset test returned on January 1, 2026: $130,000 for an individual applicant, plus $65,000 for each additional household member, so $195,000 for a couple. Anyone told during the gap that asset planning was unnecessary is now working from an assumption the legislature reversed.

One related rule hasn’t changed: estate recovery, the state’s ability to collect back what it paid out, reaches only the probate estate, not a properly funded trust (SB 833, 2016, codified at Welfare & Institutions Code § 14009.5). That’s why a funded trust still matters here even though it doesn’t shelter assets from the eligibility test itself. See Medi-Cal and your living trust: the 2026 rules.

What it costs to let the plan lapse into probate instead

A stale plan doesn’t always mean no plan. Sometimes it means a trust that was never fully funded, so the assets left outside it go through probate anyway, in Los Angeles County, since that’s where Agoura Hills sits. California sets probate fees by statute, not negotiation. Prob. Code § 10810 gives the attorney a fee, and § 10800 gives the personal representative the same schedule, charged twice, once to each. Both are calculated on the estate’s gross appraised value, not equity: a house with a mortgage is counted at its full appraised value, debt included.

The schedule: 4% of the first $100,000, 3% of the next $100,000, 2% of the next $800,000, 1% of the next $9,000,000, 0.5% of the next $15,000,000, and a reasonable amount set by the court above $25,000,000. On a $1,500,000 gross estate: 4% of $100,000 is $4,000, 3% of $100,000 is $3,000, 2% of $800,000 is $16,000, and the remaining $500,000 at 1% is $5,000. That’s $28,000 for the attorney, and the personal representative gets the same $28,000, a combined $56,000 before extraordinary services are even discussed. That’s the bill for assets a stale plan never got around to funding into the trust. See how probate works, use the probate fee calculator, and see fees for planning ahead of that.

The three places an old plan quietly breaks

The problem is almost never the trust document itself. It’s one of three things sitting quietly outside it.

Trust funding

A trust only controls what has actually been retitled into it. A house that was refinanced, a new account, or a business interest that was never assigned all sit outside the trust and go through probate regardless of what the trust says. It’s the single most common defect I find in an otherwise well-drafted plan. See trust funding in California.

Incapacity documents

A durable power of attorney and an advance health care directive signed years ago may still name an agent who has since died, moved away, or is simply no longer the right person for the job. These are the documents a hospital or a bank actually asks for during a crisis, and the ones people forget to update because nobody reads them until there’s an emergency. See incapacity planning in California.

Beneficiary designations

A retirement account, a life insurance policy, and a payable-on-death account all pass by whatever form is on file with the institution, not by the trust or will. That form controls even when it contradicts the rest of the plan, and it’s rarely reviewed after the initial paperwork. See the beneficiary designation audit.

Questions Agoura Hills clients ask

My trust was signed before 2021. Does Prop 19 mean I need to redo it?

Not necessarily, but it needs a review, particularly if the trust holds a rental or vacation property you intend to pass to your children.

I moved to Agoura Hills from another state. Is my old will still valid?

Often it’s still legally valid, but that doesn’t mean it still fits. California’s community property rules and how its courts treat a trust drafted under another state’s law make a move across state lines one of the clearest reasons for a review rather than an assumption.

Which county handles probate for Agoura Hills?

Agoura Hills is in Los Angeles County, so an unfunded estate here goes through the Los Angeles County Superior Court on the statutory fee schedule described above.

How do I know if my plan is actually stale?

If any of the seven events above have happened since you signed, or you can’t remember the last time an attorney looked at the documents, that’s the answer. A short review is far cheaper than finding out at the wrong moment.
