Professional Fiduciary Cost: What to Expect and When It's Worth It

What Professional Fiduciaries Charge

Professional fiduciaries — individuals or corporate trustees who manage estates, trusts, or conservatorships on behalf of families — may charge using different fee structures:

Percentage of estate value. One Los Angeles fiduciary's published schedule sets fees for ongoing trusts and post-death administration case by case, at 1% to 2% of trust or estate value annually, or according to the governing document.

Hourly rates. One Los Angeles fiduciary's published schedule lists professional fiduciary rates of $225 to $295 per hour and support staff rates of $125 to $200 per hour. Rates depend on the provider, staff, and matter.

Flat fees. Some fiduciaries offer a flat fee for defined-scope work — a simple estate administration with few assets, for instance. Ask the provider for a written quote covering the agreed scope.

Corporate trustees (bank trust departments) generally charge less per dollar managed on large estates but impose minimum asset thresholds — often $500,000 to $1 million — and layer on transaction fees for real estate sales, tax preparation, and account closures.

When Hiring a Professional Fiduciary Makes Sense

Not every estate needs one. A professional fiduciary earns their fee in specific situations:

No willing or capable family member. If the named executor has declined, is incapacitated, or lives overseas with no ability to manage a U.S. estate, a professional fiduciary steps in without the emotional entanglements.

High-conflict families. When siblings are fighting over the estate, a neutral third party with no personal stake can make decisions without accusations of favoritism. The cost of a professional fiduciary is almost always less than the cost of litigation — estate mediation alone runs $3,000 to $8,000, and contested probate can easily exceed $50,000 in attorney fees.

Complex assets. Estates with rental properties, business interests, mineral rights, or assets in multiple states or countries require specialized knowledge that most family executors don't have.

Conservatorships and guardianships. Courts frequently appoint professional fiduciaries to manage the finances of incapacitated adults, particularly when family members have conflicts of interest or a history of financial mismanagement.

Executor burnout. Some families start the process themselves and bring in a professional fiduciary midway through when the workload becomes unmanageable. This is perfectly legal — the existing executor can petition the court to appoint a co-executor or successor.

How to Find and Vet a Professional Fiduciary

Licensing. California licenses non-family professional fiduciaries covered by the Professional Fiduciaries Act through the Professional Fiduciaries Bureau. Other states use different frameworks; check your state's requirements.

Bonding and insurance. A reputable professional fiduciary carries errors-and-omissions insurance and is bonded. Ask for proof before signing an agreement.

References. Request at least three references from attorneys or accountants who have worked with the fiduciary on previous estates.

Fee transparency. Get the full fee schedule in writing before engagement. Ask specifically about additional charges: Are court appearances billed separately? Is there a fee for preparing the estate accounting? What about mileage and administrative overhead?

Regulatory history. In California, use the Professional Fiduciaries Bureau lookup to verify an active license and review any posted disciplinary documents. For corporate trustees, check the regulator for the bank's charter, such as the OCC, FDIC, or a state banking department; use FINRA BrokerCheck for an individual registered broker.

Professional Fiduciary vs. Family Executor

The decision often comes down to a cost-benefit analysis. A family executor typically waives compensation or takes a modest statutory fee — California's sliding scale starts at 4% of the first $100,000, and New York's starts at 5%. A professional fiduciary charges market rates on top of that.

But a family executor who makes mistakes — distributing assets before creditor claims are resolved, missing tax deadlines, or commingling estate funds — can face personal liability that dwarfs any professional fiduciary's fee. If your estate involves complexity or conflict that exceeds your comfort level, the cost of professional management is often the cheaper path.
