What Is a Private Fiduciary?

A private fiduciary is a licensed professional who is paid to manage the financial and personal affairs of another person — acting as trustee, conservator, guardian, agent under a power of attorney, or personal representative of an estate. Unlike a bank trust department or a large financial institution, a private fiduciary is typically an individual or small practice — a real person with a license, a case load, and a direct relationship with their clients. Unlike a family member serving in the same role, a private fiduciary is professionally trained, legally accountable to a state licensing authority, and has no personal financial stake in the outcome of the decisions they make.

For tech workers building an estate plan that includes a special needs trust for a child with a disability, the private fiduciary is often the most important person in the plan after the attorney who drafts it. The trust can be perfectly structured — the right distribution standard, the right beneficiary protections, the right tax provisions — and still fail if the person managing it after the parents are gone lacks the knowledge, objectivity, or longevity to do the job well. A private fiduciary is specifically trained to do exactly this, for the full duration of a beneficiary's life.

What Private Fiduciaries Do

A private fiduciary can serve in multiple legal capacities, often simultaneously for the same client:

Trustee is the most common role in estate planning contexts. As trustee of a special needs trust, a private fiduciary manages the trust's assets, makes distribution decisions in accordance with the trust's terms, files annual tax returns for the trust, maintains records, and coordinates with the beneficiary, their care team, and other professionals. For a special needs trust that may operate for 40 or 50 years after the parent's death, the trustee role requires sustained professional engagement — not a one-time act.

Conservator is a court-supervised role in which the fiduciary manages either the financial affairs (conservator of the estate) or the personal care decisions (conservator of the person) of someone who has been determined by a court to lack capacity to manage their own affairs. Adults with intellectual or developmental disabilities who are not capable of managing their own finances may have a conservator of the estate in addition to a special needs trust trustee — sometimes the same person serves both roles.

Guardian is similar to conservator but typically applies to the care and custody of a minor child. After the parents of a child with a disability die, a guardian manages the child's daily life and personal decisions. The guardian and the trustee may be different people — the guardian focuses on the person, the trustee focuses on the assets.

Agent under durable power of attorney allows the fiduciary to manage financial transactions, sign documents, and act on behalf of a client who has granted the authority — without court involvement.

Personal representative (executor) manages the administration of a deceased person's estate — gathering assets, paying debts, filing final tax returns, and distributing the estate according to the will.

Private Fiduciary vs. Family Member Trustee

Most parents instinctively name a sibling, close friend, or other trusted family member as the trustee of their child's special needs trust. The impulse is understandable — they want someone who loves their child to manage the trust. But the role of trustee is a legal and financial one, not simply an emotional one, and the qualities that make someone a caring family member are not the same qualities that make someone an effective trustee.

The case for a family member: Loves the beneficiary deeply. Understands their history, preferences, and personality. Available informally. No professional fees.

The case against a family member: May lack knowledge of SSI and Medicaid rules — one distribution mistake can disqualify the beneficiary from benefits. Faces conflicts of interest if they are also a remainder beneficiary who inherits whatever the trust doesn't spend. May predecease the beneficiary or become incapacitated themselves. Has no professional accountability — no license to lose, no regulator to answer to. Bears the psychological burden of managing a loved one's affairs without professional support.

The case for a private fiduciary: Trained specifically in trust administration, government benefits rules, and fiduciary law. Professionally licensed and regulated. Has no personal stake in how much or how little the trust distributes. Carries professional liability insurance. Will not predecease a young beneficiary if a corporate entity or successor arrangement is in place. Can be removed and replaced if performance is unsatisfactory.

Many families use a co-trustee model: a family member serves as co-trustee to maintain the personal relationship and knowledge of the beneficiary, while the private fiduciary serves as co-trustee for professional oversight and technical compliance. This structure captures the emotional intelligence of family involvement alongside the professional accountability of a licensed fiduciary.

Licensing in California: The Professional Fiduciaries Bureau

California has one of the most developed professional fiduciary licensing systems in the country, administered by the Professional Fiduciaries Bureau (PFB), a division of the California Department of Consumer Affairs. The Bureau was established by Senate Bill 1550 in 2006 and began licensing fiduciaries in 2008.

To obtain a California professional fiduciary license, an applicant must hold at least a bachelor's degree or demonstrate equivalent fiduciary experience, complete 30 hours of approved pre-licensing education (including at least 1 hour in cultural competency), pass a state licensing examination, pass a fingerprint-based background check, and pay a $600 application fee plus a $1,300 initial licensing fee. Once licensed, fiduciaries must renew annually at $1,300 and complete 15 hours of continuing education each year — of which at least 2 hours annually must cover ethics or cultural competency.

The Bureau maintains a public license lookup at fiduciary.ca.gov where anyone can verify whether a specific individual holds a valid California license and review any disciplinary history. Before engaging a private fiduciary, always verify their license status directly through the Bureau's website.

The Professional Fiduciary Association of California (PFAC) — pfac-pro.org — is the primary professional association for California licensed fiduciaries. PFAC membership is voluntary but indicates a fiduciary's commitment to professional development and peer accountability. PFAC's member directory is a useful starting point for finding licensed fiduciaries by region.

Licensing in Other States

California's licensing system is among the most rigorous in the country, but other states have their own frameworks. There is no federal licensing standard for private fiduciaries. In states without a dedicated licensing statute, a private fiduciary may operate under broader financial professional or trust company regulations, or may be subject to court oversight in conservatorship and guardianship matters rather than a dedicated regulatory regime.

For tech workers in Washington, Oregon, or Texas — other states where significant concentrations of tech industry employees live — the regulatory environment differs from California. Washington has a rigorous court-based certification system for professional guardians and conservators — the Certified Professional Guardian and Conservator (CPGC) program, governed by Washington Supreme Court General Rule 23 and administered through the Washington Courts CPGC Board. Candidates must complete the University of Washington's certificate program and pass a stringent certification process. The system is judicial rather than consumer-protection-oriented, which means CPGCs operate as officers of the court rather than under a licensing bureau. Oregon has no standalone bureau but courts increasingly require national certification through the Center for Guardianship Certification (CGC). Texas does not have a standalone professional fiduciary licensing law; fiduciaries in Texas typically operate under court supervision or as bank trust departments.

If you are naming a successor trustee who will manage a special needs trust in a state other than California, confirm what licensing or credentialing framework applies in that state before finalizing the appointment.

How to Find a Private Fiduciary

PFAC member directory (California). The Professional Fiduciary Association of California maintains a searchable directory of members at pfac-pro.org. Filter by county to find licensed fiduciaries who serve your geographic area.

California Professional Fiduciaries Bureau. The Bureau's license lookup at fiduciary.ca.gov lists all active California licensees and allows verification of license status and disciplinary history.

Special Needs Alliance referrals. The Special Needs Alliance (specialneedsalliance.org) is a national network of attorneys who specialize in special needs planning. Member attorneys work with private fiduciaries regularly and can provide referrals to experienced fiduciaries in your area who have specific SNT experience.

The SNT drafting attorney. The attorney who drafts the special needs trust will typically have relationships with private fiduciaries they have worked with on other clients' trusts. This is one of the most reliable referral channels because the attorney can assess both technical competence and communication style.

Interview process. Before naming a private fiduciary in a trust document, conduct a direct interview. Key questions: How many special needs trusts do you currently administer? Are you familiar with SSI's in-kind support and maintenance rules? How do you handle benefit redeterminations? What is your succession plan if you retire or become incapacitated? What are your fees?

Costs: What to Expect

Private fiduciary fees vary by region, complexity of the trust, and the scope of services required. Common structures:

Percentage of assets under management: Most common for trust administration. Typically ranges from 0.75% to 1.5% of trust assets annually. On a $1,000,000 SNT, this translates to $7,500–$15,000 per year. Some fiduciaries also charge a minimum annual fee regardless of asset size.

Hourly rate: More common for conservatorship and guardianship work where time spent on personal care decisions does not scale with asset value. In California in 2026, licensed professional fiduciaries typically charge $180–$250 per hour for their own time, with support staff billed at $65–$130 per hour depending on the firm. Rates below $150/hour for a licensed fiduciary are uncommon and generally reflect only administrative or support-level work. Rates vary by market — Bay Area and Los Angeles fiduciaries trend toward the higher end of the range.

Flat annual fee: Some fiduciaries offer a flat fee for defined services, particularly for simpler trust structures with predictable distribution patterns.

Fiduciary fees are a legitimate and often deductible expense of trust administration — they are paid from trust assets, not by the beneficiary personally, and do not count as income to the beneficiary for SSI purposes.

One important note: a private fiduciary's fee is an ongoing cost that should be modeled when sizing the trust. A trust funded with $500,000 paying 1.0% annually in fiduciary fees is spending $5,000 per year in fees before any distributions to the beneficiary. For a trust intended to last 40 years, total fee costs matter alongside investment returns and distribution patterns.

The Co-Trustee Model in Practice

The most functional arrangement for many special needs trusts is a co-trustee structure pairing a family member with a licensed private fiduciary. The family co-trustee brings personal knowledge of the beneficiary — their daily routines, their relationships, their preferences for how money is spent. The professional co-trustee brings legal and financial expertise, compliance knowledge, and accountability.

In practice, the co-trustees typically divide responsibilities: the family co-trustee identifies distribution needs and advocates for the beneficiary's quality of life; the professional co-trustee reviews distributions for SSI/Medicaid compliance, manages investments, files tax returns, and maintains records. Disputes between co-trustees are governed by the trust agreement — most SNTs include a tiebreaker provision or a process for resolving disagreements.

The co-trustee model also provides continuity. If the family co-trustee dies or becomes incapacitated, the professional co-trustee continues administering the trust without interruption. A successor family co-trustee can then be appointed according to the trust's terms.
