A private trust company is a company a family forms so that company can serve as trustee of that family’s trusts. It is not a bank trust department, and it is not a trustee you hire from a list. The family, or a trust the family already has, usually owns it. Directors and committees then do the trustee’s work under written rules.
Talk with Von Rock Law about a private trust company
Families in San Francisco and the wider Bay Area ask about this often. A living trust may hold a business, several properties, or a concentrated stock position. No relative wants the trustee job alone. The question is not whether trusts are useful. It is whether this family should build its own trustee.
California does not treat that choice as a casual one. A company that engages in the trust business needs authority from the state’s financial regulator, unless a specific exemption applies. This guide explains the idea, the California rules that matter, and the questions to settle before anyone files papers.
What Is a Private Trust Company?
A private trust company, often called a PTC or a family trust company, is an entity created for one purpose. Estate-planning writers describe it the same way: a family trust company used to preserve wealth, not a firm that takes on the public. It acts as trustee for one family, or for a small group of related trusts. It does not advertise trust services to the public. It does not take on strangers as clients.
Think of it as a permanent seat at the trustee’s desk. People come and go. The company stays. A parent can sit on an investment committee now. A niece can join later. The trust document can keep naming the same trustee, which is the company, even as the people change.
Most PTCs are corporations or limited liability companies. A board oversees the company. Separate committees often handle investments, distributions, and records. Some families also hire an administrative firm to keep books, pay bills, and prepare reports. The PTC remains the trustee. The helpers do not replace it.
That split is the point. A traditional corporate trustee bundles custody, investing, distributions, and paperwork into one institution. A private trust company lets the family unbundle those jobs. The people who know the operating business can sit on the investment side. People with no personal stake in a payout can sit on the distribution side.
Two labels get mixed up in search results, so it helps to separate them:
- Family PTC. Formed by one family to trustee its own trusts. This is the structure this article covers.
- Commercial firm that uses the name. Some national companies are named “The Private Trust Company” and serve many unrelated clients. That is a public trust business, not a family PTC.
If a website invites any advisor’s clients to open a trust account, you are looking at the second kind. A true private trust company has no public clients.
Who Owns a Private Trust Company, and Who Runs It?
Ownership and control are different jobs, and mixing them up is a common planning mistake.
The owner is often the family, a senior generation, or an existing trust. Ownership decides who holds the equity and who can sell or dissolve the company. It does not, by itself, decide who approves a distribution to a beneficiary.
Control sits with the board and the committees. A typical layout looks like this:
| Role | Who often serves | What they decide |
|---|---|---|
| Owner. | Family members or an existing family trust. | Who holds the equity and major company changes. |
| Board. | A mix of family and outside advisors. | Oversight, officers, and big-picture risk. |
| Investment committee. | Family members plus an advisor. | How trust assets are invested. |
| Distribution committee. | People who are not the recipients. | Whether and when to pay beneficiaries. |
| Administrator. | Family office or outside firm. | Books, bills, tax coordination, and files. |
The distribution committee is the piece tax counsel watches most closely. If the person who receives a payment is also the only person who can approve it, the tax treatment of an irrevocable trust can be at risk. Many families put disinterested relatives or outside advisors in that seat on purpose.
None of this is automatic. The operating agreement, the bylaws, and the trust itself have to say who may serve, who must step aside, and what a deadlock looks like. A lawyer should draft those rules with the family’s tax advisor, not after the company is already acting as trustee.
How Is This Different From Hiring a Corporate Trustee?
A corporate trustee is an outside institution you appoint. A private trust company is an institution you build. Both can serve as trustee. They solve different problems.
Families usually compare three paths:
- An individual trustee. A spouse, an adult child, or a friend. Personal knowledge is high. Continuity and free time are not.
- A hired corporate trustee. A bank trust department or a public trust company. Systems and staff are built in. The family gives up day-to-day control, and some institutions will not hold a family business.
- A private trust company. The family’s own entity. Control and continuity stay inside the family. Cost, governance, and licensing questions stay there too.
Von Rock Law’s guide to a corporate trustee in California walks through the hired-institution path. This article stays on the family-owned path. Many families use both ideas over time. They hire a corporate trustee now, and they revisit a PTC when the next generation is ready to take seats on a board.
A PTC does not remove fiduciary duty. The company, once it accepts the trust, still has to follow the trust instrument and California trust law. Directors do not get a free pass because they share a last name with the beneficiaries. If you want the baseline duties spelled out, see California trustee duties under the Probate Code.
What Does California Law Say About the Trust Business?
California’s trust-company rules live in the Financial Code, not only in the Probate Code. The practical gate is Financial Code section 1550. It says no corporation shall engage in the trust business unless three things are true. Its articles meet the statute’s content rules. It holds a certificate of authority from the commissioner, or, if it is a bank, the commissioner has authorized the trust business. And it has deposited money or securities with the State Treasurer as the statute requires.
The commissioner is the head of the Department of Financial Protection and Innovation, the state agency that licenses trust companies and banks. “Trust business” is a defined term. It is not a synonym for “helping with a family trust.” A company that holds itself out as a trustee for hire is in different territory from a relative who serves under one trust document.
Section 1553 lists people who are exempt from that licensing rule. The exemptions that families actually bump into are:
- A natural person serving as trustee of one or more trusts, if at least one trustor is a family member of that trustee. The statute defines family member, and the list is specific. It is not “anyone we consider family.”
- A California lawyer or certified public accountant, or their professional corporation. They must be acting as trustee of a trust they set up for a client. They also must not advertise a trust business in the state.
- A nonprofit, when acting as trustee is incidental to the purpose it was organized for, and other nonprofit limits still apply.
- A person a court appoints as receiver, trustee, or other fiduciary, acting under that appointment.
- A person licensed as a professional fiduciary under the Business and Professions Code.
Read that list closely. The family exemption is for a natural person, meaning a human being, not a corporation or an LLC. Forming a company to act as trustee can take you out of the exemption that would have covered Uncle David serving in his own name.
That is why “we will just have our LLC be the trustee” is not a complete plan. It may be the right structure. It may also be an unlicensed trust business. The difference depends on what the company does, whose trusts it serves, and whether an exemption actually fits. Those are questions for counsel who can read the Financial Code against the real facts, not for a template.
Probate Code section 83 defines “trust company” for probate purposes as an entity that has qualified to engage in and conduct a trust business in this state. Probate Code section 300 then says a trust company may be appointed as a trustee in the same manner as an individual. The appointment rule does not replace the licensing rule. A company still has to be the kind of entity the statute is talking about.
Other states market lighter PTC regimes. Wyoming, Nevada, New Hampshire, South Dakota, and Tennessee are the names that come up most often. A Bay Area family that forms the company elsewhere still has California issues if the trusts, the real estate, the beneficiaries, or the decision-makers are here. Situs is a legal conclusion, not a mailing address. Do not pick a state from a blog chart.
When Does a Private Trust Company Make Sense?
A PTC is a tool for a narrow set of facts. It is usually discussed when the family is already in ultra-high-net-worth territory, often with several trusts, an operating business, or assets a public trustee will not hold. Cost is the filter. Formation, legal drafting, tax opinions, a board, insurance, and annual administration are ongoing, not a one-time filing fee.
The situations where families and their advisors look at it seriously:
- The trust owns an operating company, and outside trustees will not hold a controlling stake or will bury ordinary decisions in due diligence.
- The trust holds real estate, a concentrated stock lot, or other assets a bank’s approved list does not cover.
- No single relative can serve for the decades the trust is meant to last, but the family does not want a stranger as sole trustee.
- The senior generation wants the next generation to learn governance by sitting on a real board, with outside advisors in the room.
- Distributions, investments, and family employment need to be separated so one person is not grading their own homework.
It is a poor fit when the estate is a house, a brokerage account, and a modest living trust. In that case an individual successor trustee, or a short-term professional, is usually simpler. Start with Von Rock Law’s page on what a trustee is. The firm’s trustee services page shows how outside help differs from a family-owned company.
It is also a poor fit when the family cannot fill the seats. A PTC with one overworked sibling and no outside member is an individual trustee wearing a corporate name. You still need people who will show up, keep minutes, and say no.
What Should a Bay Area Family Review First?
Work through the decision in order. Skipping ahead to “which state” wastes the legal budget.
- Name the problem. Write down what the current trustee cannot do. If the issue is a missing deed or an unfunded account, a PTC will not fix it. Trust administration might.
- Read the trust. Some documents name a specific successor and make a change hard. Others allow the family to appoint a corporate trustee. The paper controls.
- List the assets. A family business, out-of-state property, and retirement accounts raise different issues. Note what a public trustee has already refused.
- Map the people. Who can serve on a board for ten years? Who must not approve their own distribution? Who is the backup if someone dies or moves?
- Ask about licensing. Have a California lawyer tell you whether this company would be in the trust business under section 1550, and whether any exemption in section 1553 could apply. Get that answer in writing before you form the entity.
- Price the whole stack. Include formation, a tax opinion, annual legal and accounting help, fiduciary insurance, and any outside administrator. Compare that number with the fee quote from a hired corporate trustee.
- Decide who drafts what. The operating agreement, the committee charters, and any trust amendment should be drafted together. They have to match.
Bring the trust, a current asset list, and the names of the people you would actually appoint. A consultation is more useful with those three things on the table.
If the real need is help administering a trust after a death, rather than building a new trustee, start with trust administration and probate services. A PTC is a planning structure. It is not the first step in settling an estate.
What Can Go Wrong?
The structure fails in predictable ways. Knowing them early is cheaper than unwinding them.
Licensing drift. The company starts as “our family’s trustee” and later accepts a cousin’s separate trust, or a friend’s. One extra client can change the analysis under the trust-business rules. So can a website that invites the public in.
Tax-sensitive control. The wrong person on the distribution committee can undermine the reason the irrevocable trust was created. This is a tax question. Have the tax advisor in the draft, not at the signing.
Paper trustee, human reality. If the board never meets and one person signs everything, beneficiaries can argue there was no real governance. Minutes, reports, and a real process are part of the duty, not decoration.
Situs theater. Forming the company in a famous trust state while every meeting, every property, and every beneficiary stays in California does not, by itself, move the trust. Courts and tax authorities look at facts.
No exit. Someone needs the power to resign, to replace a director, and to hand the trusts to a successor if the PTC should be wound down. Build that path while everyone is still speaking.
A private trust company can also be the right answer. Families with complex assets and a real bench of people use them to keep decision-making close without asking one sibling to carry a thirty-year fiduciary job. The test is whether you can staff it, license it correctly, and pay for it after the novelty wears off.

Frequently Asked Questions
What is a private trust company?
It is a company formed to act as trustee only for one family’s trusts. It does not offer trust services to the public. The family usually owns it, and a board and committees carry out the trustee’s work.
Who owns the private trust company?
Often the family, members of an older generation, or an existing family trust. Ownership is not the same as the power to approve distributions. Distribution power usually sits with a committee of people who are not the ones receiving the money.
Does California let a family corporation serve as trustee without a license?
Not as a blanket rule. Financial Code section 1550 requires a corporation in the trust business to hold state authority and to make a required deposit. Section 1553 exempts certain natural persons, lawyers, accountants, nonprofits, court appointees, and licensed professional fiduciaries. A family LLC is not on that list by name. Whether your facts fit an exemption is a legal question, and you should have it answered before the company accepts a trusteeship.
How much does it cost to set up a private trust company?
There is no single California price. Families should budget for entity formation, trust amendments, a tax opinion, annual accounting, fiduciary liability coverage, and often an outside administrator. For many households that total is higher than hiring a corporate trustee. Ask both sides for a written scope before you choose.
Is a private trust company the same as a family office?
No. A family office manages investments, bills, and staff for the family. A private trust company is the trustee of the family’s trusts. Some families have both. The office may do the paperwork. The PTC still holds the fiduciary role.
