A California professional fiduciary is a state-licensed individual hired to manage the personal, financial, or legal affairs of someone who cannot handle those matters alone. The profession is regulated under the Professional Fiduciaries Act, enacted in 2006, and overseen by the Professional Fiduciaries Bureau within the Department of Consumer Affairs.1California Legislative Information. SB-1550 Professional Fiduciaries Act Families typically bring one in to serve seniors, people with disabilities, or minors when relatives are unavailable, unwilling, or in conflict with one another.
Roles a Professional Fiduciary Fills
A professional fiduciary steps into positions that would otherwise fall to a family member, a trusted friend, or a public agency. The common thread is that someone needs a responsible person to act on their behalf, and no suitable volunteer exists. Licensed fiduciaries serve in five main capacities:2Professional Fiduciaries Bureau. What Is a Professional Fiduciary
- Conservator, appointed by a court to manage the personal care, finances, or both for an adult who can no longer make safe decisions about their own welfare or property.
- Guardian, court-appointed to oversee the personal and financial affairs of a minor whose parents cannot care for them.
- Trustee, managing trust assets and carrying out distributions according to the trust document.
- Agent under a durable power of attorney, making financial or healthcare decisions for someone who has become incapacitated, as authorized in a document signed while the person still had capacity.
- Personal representative of a decedent’s estate, handling probate administration and asset distribution after a death.
Why Families Hire an Outsider
The value a professional fiduciary brings is neutrality. In families with complex assets, blended households, or long-standing disagreements about care, a licensed outsider can make decisions without the emotional entanglement that derails family-member fiduciaries. Neutrality matters most in conservatorships, where relatives sometimes disagree about whether a loved one needs help at all.
Hiring a professional also brings expertise. A fiduciary who has handled dozens of conservatorships knows the court reporting cycle, understands how to inventory assets, and has working relationships with the attorneys, accountants, and care managers a complicated case tends to require.
Duties and Standards of Care
A licensed professional fiduciary is legally required to act in the client’s best interest at all times. That means managing assets carefully, protecting the client’s well-being, and making decisions that reflect what the client would have wanted. The fiduciary must consider the client’s ethnic, religious, and cultural values when making care decisions.2Professional Fiduciaries Bureau. What Is a Professional Fiduciary
Conflict-of-interest avoidance is foundational. A professional fiduciary cannot personally benefit from transactions involving the client’s estate or trust. Self-dealing, dual relationships, and any arrangement in which the fiduciary’s interests compete with the client’s are prohibited. A fiduciary who rents estate property to a relative or invests estate funds in a personal business has crossed the line.
Day-to-day, the fiduciary inventories assets, pays legitimate expenses, and prepares regular accountings. In court-supervised matters such as conservatorships, the fiduciary submits formal financial accountings and personal status reports to the judge. A trustee answers to the beneficiaries and follows the trust document’s terms rather than a court’s standing orders.
Fiduciaries often hire attorneys, accountants, and investment managers to handle specialized tasks at the estate’s expense. Delegation does not shift responsibility. The fiduciary remains accountable for the quality of that work, and a poor hiring decision that causes losses falls on the fiduciary.2Professional Fiduciaries Bureau. What Is a Professional Fiduciary
Before a court issues letters of conservatorship or guardianship, the appointed fiduciary must post a bond that protects the estate against mismanagement. The amount reflects the value of personal property, estimated annual income, and expected public benefit payments, and the premium is generally paid from the estate.3California Legislative Information. California Probate Code 2320 (2025) Many fiduciaries also carry errors-and-omissions insurance covering claims of negligent management or poor selection of outside professionals.
What It Costs
Professional fiduciaries in California typically charge hourly rates, though some use flat fees for simpler engagements. Rates vary with the complexity of the estate, the level of personal care involved, and the fiduciary’s experience. For conservatorships covering both personal and financial management, hourly rates of roughly $150 to $350 are common, with higher rates in major metropolitan areas. Courts review and approve fiduciary fees in conservatorship cases, which provides a check against excessive charges.
Fees are generally paid from the estate or trust rather than out of pocket by the client’s family. For smaller estates, those costs can still consume meaningful assets. When interviewing candidates, ask specifically about the hourly rate, which tasks are billable, and how the fiduciary handles fees charged by outside professionals they hire. Clarity on billing up front heads off the most common source of family complaints.
How to Find and Appoint One
The Bureau maintains an online license verification tool where you can look up any licensed professional fiduciary and check for disciplinary actions.4Professional Fiduciaries Bureau. Licensing Application Package Information Probate attorneys and local court referral lists are other common starting points. When interviewing candidates, focus on experience with your specific situation. A fiduciary who has spent years managing conservatorships for elderly clients may not be the right choice for administering a complex trust with commercial real estate holdings.
Court Appointment
For conservatorships and guardianships, appointment happens through a court proceeding. Someone files a petition asking the court to establish the conservatorship, and the court assigns an investigator to interview the proposed conservatee, the petitioner, and sometimes other family members. The investigator files a report with the judge assessing whether the conservatorship is necessary and whether the proposed conservator is suitable.5California Courts. Conservatorship Investigation and Reports The judge makes the final appointment, and the conservator must post the bond before letters are issued.6California Courts. Conservatorships
Private Naming
Trustees and agents under a power of attorney are not appointed by courts. They are named in the legal document itself. A trust document identifies the successor trustee, and a power-of-attorney form names the agent who steps in if the principal becomes incapacitated. If you are drafting these documents, contact the professional fiduciary before naming them to confirm they are willing to serve. A nomination means nothing if the person declines when the time comes.
If Something Goes Wrong
When a fiduciary mismanages assets, the court can order a surcharge, meaning the fiduciary personally owes money back to the estate or trust. It is restitution to the people the fiduciary was supposed to protect, not a fine paid to the government, and it comes from the fiduciary’s own funds if the estate cannot be made whole otherwise. Excessive fees, unauthorized expenditures, reckless investments, and unaccounted-for spending are the usual triggers.
You can also file a complaint with the Professional Fiduciaries Bureau, either online through the Department of Consumer Affairs website or on a printed form.7Professional Fiduciaries Bureau. Filing a Complaint Against a Professional Fiduciary The Bureau investigates violations of the Professional Fiduciaries Act and its regulations, and a fiduciary is prohibited by law from billing you or the estate for time spent responding to a Bureau complaint.
The Bureau’s authority has real limits. It cannot remove a fiduciary from an appointment, interpret or enforce the terms of a trust or conservatorship, order repayment of misused funds, or override a court order. Those actions require going back to the court that made the appointment. If the conduct looks criminal, the Bureau refers the matter to law enforcement rather than investigating it itself.7Professional Fiduciaries Bureau. Filing a Complaint Against a Professional Fiduciary For most serious problems, expect to work through both channels: the court to fix the appointment and recover funds, the Bureau to address the license.
