Fiduciary describes a standard of conduct, not a particular job. Executors, trustees, agents under a power of attorney, guardians, and conservators are all fiduciaries. What unites them is that each holds power over someone else's property or wellbeing, and the law responds by demanding they exercise it for that person rather than themselves.
The duties are usually described in a few parts: loyalty, meaning no self-dealing and no conflicts you have not disclosed; care, meaning reasonable prudence in decisions; impartiality among beneficiaries where more than one exists; and accounting, meaning records good enough to demonstrate what you did and why. It is the highest standard of conduct the law routinely imposes on private individuals.
Most breaches are not theft. They are the trustee who parks estate cash in a non-interest-bearing account for two years, the executor who sells the house to their own brother at a friendly price, the agent who mixes their mother's money with their own for convenience. Casual handling of somebody else's money is the ordinary failure mode.
Liability is personal, which is the point most people appointed to these roles do not fully register when they agree. A fiduciary who breaches can be surcharged — required to repay the loss from their own funds — and removed. Good records and a willingness to hire professionals are the standard defenses.
Frequently asked
- What actually counts as a breach?
- Acting in your own interest, or being careless with someone else's. Buying estate property yourself without disclosure and consent, lending trust funds to a relative, commingling accounts, favoring one beneficiary over another, or simply letting assets sit uninvested and lose value. Note that a bad outcome is not automatically a breach — fiduciaries are judged on the prudence of the process, not on whether an investment happened to fall.
- Can I be a fiduciary and a beneficiary at the same time?
- Yes, and it is extremely common — the child who inherits half the estate is often also the executor. The conflict is structural, not disqualifying. What it demands is transparency: disclose decisions that affect your own share, document valuations with independent evidence, and get consent or court approval for anything that looks self-interested. Estates blow up when the fiduciary-beneficiary handles their own share quietly and the other beneficiaries learn about it afterward.
- Should I hire professionals or handle it myself?
- The duty of care generally expects you to seek help where the matter exceeds your competence, and the cost of appropriate professional advice is normally payable from the estate or trust rather than your pocket. A fiduciary who files a complicated tax return badly to save a fee has taken on personal risk to protect assets that were never theirs. Doing routine work yourself is fine; guessing at the complicated parts is not.
