When individuals create their estate plans, they typically name a person to be in charge of the affairs that will need handling after their passing. This person is usually referred to as the executor and will address the final tasks of the estate as it goes through the probate process.
Your loved one may not have named you as the executor of his or her estate, but you did not have a problem with that. However, you do have concerns about how the current executor is handling his or her duties. In fact, you may think that he or she is not acting appropriately.
