The Missouri Petition To Decrease Authority of Fiduciary is a legal document filed with the court by a fiduciary, such as an executor, administrator, or guardian, to request a reduction in the authority they have been given. This could be due to the fiduciary no longer needing the full scope of authority, or because they are unable to handle it. It outlines the current authority they have and what they are asking to reduce. There are two types of Missouri Petition To Decrease Authority of Fiduciary: 1) for an executor or administrator, and 2) for a guardian. The petitioner must provide details in the petition about why they are asking for a reduction in their authority. The court will then review the petition before granting the request.
