Being named trustee and serving as trustee are not the same event.
Families often talk about the trustee role as if it begins automatically when the trust document names someone. That is too loose.
In real trust administration, the office of trustee has entry rules. A person may be designated to serve, may decline, may act in limited ways before accepting, may later resign, may be removed, and may still have turnover duties after leaving office.
In plain English, trusteeship is not just a title. It is a legal office with a start, a set of responsibilities, and a clean handoff requirement at the end.
