When someone manages money, property, or business decisions for you, the relationship carries more than ordinary responsibility. A trustee may control trust assets, a power of attorney agent may access your accounts, and an LLC manager may make decisions affecting the company and its members. California law expects that person to put the protected party or entity first and to act with appropriate care.
If you are serving in one of these roles, or believe someone has misused it. Von Rock Law can help you evaluate the facts and plan a practical next step. Learn about trustee services or contact the firm for guidance tailored to your situation.
A fiduciary duty is the legal obligation to act loyally and carefully for the benefit of another person or entity. In California, that can require avoiding conflicts, protecting property, making prudent decisions, and accounting for how assets or opportunities were handled. The exact standard depends on the relationship and the governing law, so a trustee, agent, LLC member, or manager may face different duties.
Those differences matter. The relationship establishes who must be protected, what conduct is expected, and what remedies may be available when trust is broken. Start with the basic meaning of the duty, then apply it to the California roles most likely to affect your family or business.
What Is a Fiduciary Duty?
A fiduciary duty is the legal responsibility to put another person’s interests first when you have been entrusted to manage their money, property, or important legal affairs. In plain English, you are not free to treat that property as your own. You must use sound judgment, act honestly, and make decisions for the benefit of the person or entity you represent. The Consumer Financial Protection Bureau describes a fiduciary as someone entrusted to manage money or property for someone else and required to act in the beneficiary’s best interest.
That responsibility usually includes two central obligations: the duty of care and the duty of loyalty. The exact rules depend on your role and the governing document or law, but these duties provide a useful framework for understanding what is expected of you.
What does the duty of care require?
The duty of care requires you to handle another person’s property carefully and make informed, reasonably prudent decisions. You should gather the information needed to make a decision, keep accurate records, protect assets from avoidable loss, and follow the instructions that apply to your role. For example, a California trustee must administer trust property with appropriate care and skill under California Probate Code section 16040. An agent acting under a power of attorney must also observe the standard of care a prudent person would use when dealing with someone else’s property under section 4231.
Care does not mean that every decision must produce a perfect result. It means your process should be responsible and connected to the interests you are required to protect. Ignoring known risks, failing to keep records, or making major decisions without adequate information can raise concerns even when the outcome was not intentional.
What does the duty of loyalty require?
The duty of loyalty requires you to act for the benefit of the beneficiary, principal, or entity rather than for your personal advantage. You must identify and manage conflicts of interest, avoid self-dealing, and not divert an opportunity or profit that belongs to the person or entity you serve. California Probate Code section 16002, for example, requires a trustee to administer a trust solely in the interest of its beneficiaries. Section 4232 similarly requires an attorney-in-fact to act solely in the principal’s interest and avoid conflicts.
These duties can apply to trustees, personal representatives, agents under a power of attorney, and certain business owners or managers. If you are unsure what your role permits. Reviewing the governing documents and getting advice before acting can help you protect the person you serve and meet your legal responsibilities. Von Rock Law helps Bay Area families and business owners understand these obligations in the context of trusts, estates, and business relationships.
| Duty | What it requires | What it guards against |
|---|---|---|
| Duty of care | Make informed, reasonably prudent decisions and keep reliable records for the person or entity you serve. | Careless handling of assets, uninformed decisions, and avoidable losses. |
| Duty of loyalty | Act for the benefit of the beneficiary, principal, or entity rather than for personal advantage. | Self-dealing, undisclosed conflicts of interest, and diverted profits or opportunities. |
Together, these two duties form the core of most fiduciary relationships in California. The table above is a starting point. But the precise obligations on you and the remedies available to the person you serve depend on the role, the governing document, and the applicable statute.

What Fiduciary Duties Does a California Trustee Owe?
Serving as trustee means managing property for the benefit of someone else, not treating the trust as an extension of your own finances. California law requires a trustee to make decisions with care, loyalty, fairness, and accountability. The details matter because a reasonable decision can still create questions if the trustee cannot explain the decision, document the transaction, or show how it served the beneficiaries.
Duty of loyalty: Whose interests come first?
Under California Probate Code section 16002, a trustee has a duty to administer the trust solely in the interest of the beneficiaries. In practical terms, you must identify and avoid conflicts between your personal interests and the trust. You cannot use trust property for your own profit or for a purpose unrelated to the trust. You also should not take part in a transaction in which you have an interest adverse to a beneficiary. Read more about the fiduciary duty of a trustee before entering a transaction that could benefit you, a family member, or a related business.
California Probate Code section 16004 creates an important warning sign: a transaction between a trustee and beneficiary that gives the trustee an advantage is presumed to violate the trustee’s fiduciary duties. Even when a transaction appears fair, obtain informed consent only after providing complete information and consider independent legal advice.
Duty of care: What does prudent administration require?
Probate Code section 16040 requires a trustee to administer the trust with the care, skill, and caution that a prudent person would use in managing another person’s property. That usually means reviewing the trust terms, protecting assets, evaluating investments and expenses, paying valid obligations, and keeping reliable records. The standard is not perfection or hindsight. It is a disciplined process that takes the trust’s purposes, beneficiaries, assets, and circumstances into account.
Impartiality and accounting to beneficiaries
A trustee may owe duties to beneficiaries with different needs and interests. You should administer the trust impartially rather than favoring one beneficiary without a reason grounded in the trust document or California law. Clear accountings help demonstrate that the trustee is meeting that obligation. Keep statements, invoices, distribution records, valuations, tax documents, and written explanations for significant decisions. Beneficiaries may have rights to information and reports, and prompt, accurate responses can prevent a misunderstanding from becoming a dispute.
For a broader overview of fiduciary obligations during trust administration, review the trust terms and the records before taking an action that affects beneficiaries or trust property. When a conflict or contested transaction is involved, trustee-specific guidance can help you understand the risks before acting.
What Fiduciary Duty Does a Power of Attorney Agent Owe?
When you name someone as your agent under a California durable power of attorney, you give that person authority to act on your behalf. You do not give the agent permission to treat your money or property as their own. The agent, also called an attorney-in-fact, must use that authority for your benefit and within the limits of the power of attorney.
California Probate Code section 4232 states that an attorney-in-fact has a duty to act solely in the interest of the principal and to avoid conflicts of interest. In plain English, the agent must put your interests first. For an overview of how this arrangement works, see Von Rock Law’s fiduciary duty under a power of attorney.
What does acting in your best interest require?
An agent should make decisions based on your needs, instructions, and financial circumstances, not on the agent’s personal convenience or financial gain. That can include paying your bills, managing investments, handling real estate, or protecting assets when you cannot manage those matters yourself. The agent should keep your property separate from their own, maintain accurate records, and be able to explain transactions made under the power of attorney.
The agent also should not use your authority to benefit themselves, a relative, or another person at your expense. For example, transferring your property to the agent without proper authority, borrowing your funds, or steering a transaction toward the agent’s own business may raise a conflict-of-interest concern. Whether a particular transaction is authorized depends on the power of attorney and the surrounding facts.
What standard of care applies to the agent?
Under California Probate Code section 4231, an attorney-in-fact must observe the standard of care that a prudent person would use when dealing with someone else’s property. This does not require perfect judgment or guarantee a particular financial result. It does require the agent to act reasonably, pay attention to the consequences of decisions, and avoid careless handling of your assets.
A serious misuse of authority can also become relevant in a financial elder-abuse matter when the principal is an older adult or dependent adult. If you suspect unexplained withdrawals, pressure, self-dealing, or missing records, preserve account statements and other documentation promptly. Von Rock Law can help you evaluate the power of attorney, the agent’s conduct, and possible next steps under California law.
What Fiduciary Duties Do LLC Members and Managers Owe?
California law generally imposes duties of loyalty and care on members of a member-managed LLC. These duties help protect the company and the other owners from self-dealing, misuse of company opportunities, and seriously careless conduct. The operating agreement may shape how an LLC is managed, but it cannot be read in isolation from the statutory rules in California Corporations Code section 17704.09.
What does the duty of loyalty require?
The duty of loyalty requires an LLC member to put the company’s interests ahead of personal gain in situations covered by the statute. Under section 17704.09, a member must account to the LLC for property, profits, or benefits received from the use of company property or an LLC opportunity. The member also must avoid dealing with the company on behalf of an adverse party and may not compete with the LLC in the conduct of its business.
In practical terms, a member should not quietly divert a valuable client. Purchase a business opportunity that belongs to the LLC, or use company funds for a personal venture. Conflicts should be identified and handled transparently. Your operating agreement may provide procedures for disclosure, approval, or consent, so review those provisions before taking action that could affect the company.
What does the duty of care require?
The statutory duty of care is narrower than a requirement to avoid every business mistake. Section 17704.09 limits it to refraining from grossly negligent or reckless conduct, intentional misconduct, or a knowing violation of law. A disappointing business result does not automatically establish a breach. The question is whether the conduct crossed the legal threshold described in the statute.
The same statute also requires members and managers to act consistently with the obligation of good faith and fair dealing. That obligation does not create a blanket promise that every owner will agree with every decision. It does require honest performance of the LLC agreement and fair exercise of contractual rights.
How do member-managed and manager-managed LLCs differ?
In a member-managed LLC, these fiduciary duties generally apply to the members in their management role. In a manager-managed LLC, section 17704.09 provides that the duties apply to the manager, not to a member solely because that person owns an interest. The distinction matters when assessing who made the decision, who controlled the information, and who owed the statutory obligation.
If you are forming or revising an LLC, an agreement should clearly address management authority, conflicts, company opportunities, and approval procedures. Von Rock Law’s fiduciary duty in an LLC guidance can help you identify issues to discuss with California counsel.

What Happens When a Fiduciary Breaches Their Duty in California?
A fiduciary breach is more than a disagreement about whether someone followed a contract. A contract usually sets the obligations of parties dealing at arm’s length. A fiduciary, by contrast, has accepted a position of trust and must put the beneficiary’s, principal’s, or estate’s interests ahead of personal gain. That higher standard matters when a trustee, personal representative, agent, or business fiduciary makes a conflicted decision.
For example, a trustee may breach that duty by loaning trust money to themselves on favorable terms. Or by directing trust assets to an agent as a gift without proper authority. California Probate Code section 16004 prohibits a trustee from using trust property for the trustee’s own profit or for a purpose unrelated to the trust. It also addresses transactions in which the trustee has an adverse interest. A transaction that gives the trustee an advantage over a beneficiary may be presumed to violate the trustee’s fiduciary duties. Read California Probate Code section 16004.
What remedies can a beneficiary or estate seek?
The available remedy depends on the fiduciary’s role, the conduct, and the resulting harm. A court may order the fiduciary removed, particularly when continuing in the role would place assets or beneficiaries at risk. The court may also require a formal accounting, which is a documented explanation of money received, spent, invested, or transferred. An accounting can help identify whether the fiduciary acted for a legitimate trust or estate purpose.
If the evidence shows a loss, the court may order restitution or a surcharge. In plain English, that can require the fiduciary to restore money or property lost through the breach. The remedy may also address an improper profit, even when the fiduciary’s conduct did not cause a simple dollar-for-dollar loss. For a personal representative, California Probate Code section 9601 provides that a breach can result in liability for loss or depreciation in the estate. Profit made through the breach, or profit that would have accrued to the estate. The statute also refers to interest on appropriate losses or profits. Review California Probate Code section 9601.
Can a fiduciary avoid liability?
Not every poor outcome is automatically a breach. Under section 9601, a court may, in its discretion. Excuse a personal representative from all or part of liability when the representative acted reasonably and in good faith under the circumstances, and excusing liability would be equitable. That is different from saying that a fiduciary may ignore conflicts or skip documentation. If you are evaluating a suspected breach, preserve account statements, transaction records, communications, and the governing trust or appointment documents. A focused review of the fiduciary duty of a trustee can help clarify what information may matter before seeking court relief.
