Conservatorship vs. Trust Administration in California

If your parent has a properly funded living trust, you usually do not need a conservatorship to manage their money once they lose capacity: the trust’s successor trustee provision already does that job, privately, without a judge. Conservatorship is a separate, court-supervised tool for what a trust cannot reach: medical decisions, personal care, and assets that were never moved into the trust in the first place.

A parent loses capacity, and the family’s first instinct is often “we need a conservatorship.” Sometimes that’s right. Often, if the parent already has a properly funded trust, it’s not necessary at all, and pursuing one wastes time, money, and court oversight that a trust was specifically designed to avoid. Knowing the difference matters before you file anything.

What trust administration does when a parent loses capacity

A funded trust is built to hand off financial control without ever going near a courtroom. If your parent created a revocable living trust and moved their major assets into it (their house, investment accounts, bank accounts retitled in the trust’s name), the trust likely already names a successor trustee to take over the moment your parent can no longer manage their own affairs.

Most well-drafted trusts include an incapacity provision: a mechanism, often requiring one or two physician letters confirming incapacity, that triggers the successor trustee’s authority automatically, with no court involvement. Once triggered, the successor trustee steps in and manages trust assets for your parent’s benefit: paying bills, managing investments, handling real estate, distributing income for their care.

No judge has to approve routine decisions. No annual court accounting is required unless the trust itself demands one or a beneficiary later requests one. This is, by design, the private, low-friction alternative to court supervision.

What conservatorship does that a trust can’t

Conservatorship is a court proceeding, filed under Probate Code section 1800 and following sections, where a judge appoints someone (a conservator of the estate, the person, or both) to manage the affairs of someone the court finds substantially unable to manage their own financial resources or resist fraud and undue influence, or to provide for their own personal needs.

Unlike trust administration, conservatorship involves ongoing court supervision: an initial court investigator review, letters of conservatorship, and typically annual accountings filed with and reviewed by the probate court.

Conservatorship covers ground a trust simply can’t. A trust only controls assets actually inside it. It has no authority over medical decisions, housing decisions, or assets your parent never transferred into the trust, like a car, or an account someone forgot to retitle. If your parent has significant assets outside the trust, or needs someone with authority over medical and personal care decisions, conservatorship may be necessary regardless of what the trust says.

When you need both

These tools aren’t always either-or. A person can have a fully funded trust handling their financial life through a successor trustee, and still need a conservatorship of the person if they require someone with legal authority over medical decisions and living arrangements, and no valid, sufficiently broad advance health care directive exists. In that scenario, the trustee handles the money; the conservator of the person handles the care decisions. They run in parallel, addressing different halves of the same problem.

When conservatorship becomes necessary despite a trust

A trust doesn’t solve every problem, even when it’s well drafted. A few situations push a family toward court regardless of how the trust is written.

No workable successor trustee

If the named successor trustee is unwilling or unable to serve, and there’s no workable backup named in the document, court involvement may become necessary to get someone with authority in place.

Family disputes over capacity or control

If family members are fighting over whether your parent actually lacks capacity, or over who the rightful successor trustee is, a conservatorship (or a Probate Code section 17200 petition to the trust court) may be the only way to get a binding answer.

Suspected financial exploitation

If there’s reason to believe someone is exploiting your parent financially, a conservatorship can provide court-supervised oversight that a private trust administration doesn’t automatically include.

The overlap with trust litigation

Capacity questions sit at the center of both systems. The same medical evidence that supports, or defeats, a conservatorship petition often matters just as much in a lack of capacity challenge to a trust amendment signed around the same time. And if you’re worried that the person now controlling trust assets, whether formally appointed or not, is mismanaging or exploiting your parent, that concern may point toward trustee removal, a conservatorship petition, or both, depending on what’s actually happening day to day.

Getting the right tool for the actual problem

Filing for a conservatorship when a trust already handles everything wastes money and invites court oversight your parent’s estate plan was built to avoid. Skipping a needed conservatorship because “there’s a trust” can leave nobody with legal authority over medical decisions when it matters most. The right answer depends on what’s actually in the trust, what’s actually still outside it, and what kind of decisions your parent can no longer safely make.

The honest caveat

Neither tool is a complete solution by itself, and the paperwork doesn’t tell you the whole story until someone reads it against your parent’s actual situation. A trust that looks airtight on paper can still leave a car, a small side account, or a timeshare outside its reach. A conservatorship, once filed, is public, slower to set up than most families expect, and comes with court fees and ongoing reporting obligations that don’t disappear once the conservator is appointed. If your family is already in conflict over capacity or control, neither route avoids that fight, it just moves it into a courtroom where a judge decides instead of the family sorting it out privately.

Frequently asked questions

Does my incapacitated parent need a conservatorship if they already have a trust?

Not necessarily. If your parent’s trust is funded and includes an incapacity provision, the named successor trustee can usually take over financial management with no court involvement. Conservatorship becomes necessary when assets sit outside the trust, when someone needs authority over medical or personal care decisions, or when there’s a dispute the trust can’t resolve on its own.

What triggers a successor trustee’s authority when a parent loses capacity?

Most well-drafted trusts include an incapacity provision, often requiring one or two physician letters confirming the person can no longer manage their own affairs. Once that’s satisfied, the successor trustee steps in automatically. No judge approves it, and no annual court accounting is required unless the trust itself demands one.

Can a trust cover medical decisions the way a conservatorship does?

No. A trust only controls property that was actually transferred into it. It has no authority over medical decisions, housing decisions, or personal care. If no valid advance health care directive covers those decisions and someone needs legal authority over them, a conservatorship of the person may be necessary even with a fully funded trust in place.

What does conservatorship cost that trust administration avoids?

Conservatorship under Probate Code section 1800 involves an initial court investigator review, letters of conservatorship, and typically annual accountings filed with and reviewed by the probate court. Trust administration by a successor trustee generally requires none of that unless the trust document or a beneficiary specifically demands an accounting.

Can someone need both a conservatorship and a successor trustee at the same time?

Yes. A person can have a fully funded trust with a successor trustee managing their financial life, and still need a conservatorship of the person if someone requires legal authority over medical decisions and living arrangements and no sufficient advance health care directive exists. The trustee handles the money, the conservator handles the care decisions.
