What it means to be an executor/executrix
Being named an executor means that someone who's passed away is relying on you to handle the tasks of transferring their assets to the right people—like family members or relatives who are identified in legal documents (a will, for example). In some cases, Vanguard can only take direction from an executor: we need to know who, legally speaking, is authorized to tell us where to move a deceased person's assets.
Sometimes, an executor will need to play a more active role to coordinate the transfer of assets (like when there are no beneficiaries listed on the accounts). Other times, they'll play a more passive role (like when there are beneficiaries listed on the accounts). It really depends on the circumstances. The information here outlines the process, in a general way, for executors who need to play a more active role.
