A monetary liability imposed by the California Probate Court against a fiduciary (such as an executor, administrator, trustee, or conservator) personally. Its purpose is to compensate the estate, trust, beneficiaries, or conservatee for financial losses incurred due to the fiduciary’s improper actions or failure to act. A surcharge may be ordered when a fiduciary commits a breach of duty that results in financial loss. Common grounds include negligence in managing assets (e.g., failing to insure property, collect debts, or invest prudently according to the Prudent Investor Act), misappropriation or embezzlement of funds, self-dealing or conflicts of interest that cause harm, failure to make property productive, incurring unreasonable expenses, making improper payments or distributions, or other violations of the fiduciary’s duties of loyalty, care, and prudence under the California Probate Code. A surcharge is typically sought through an objection to the fiduciary’s accounting or a separate petition filed with the court.
