Common Pitfalls

- Do not confuse with доверенное лицо (trusted person) or агент (agent), as these lack the specific legal weight of fiduciary. Closest conceptual equivalent is фидуциарный, but it is a direct loanword with limited native recognition.
Common Mistakes
- Using 'fiduciary' to mean simply 'financial' (e.g., 'fiduciary advice' vs. 'financial advice'). Mispronouncing it as /faɪˈdjuːʃəri/. Using it without the necessary context of legal trust.
