The first thing to consider is to try to resolve any concerns with the executor of the estate. It is also possible to apply for an inventory and account for information about the extent of the estate. As a last resort, you can apply to remove or replace an executor if they are acting unreasonably in the administration of an estate. The removal of an executor would involve a court hearing and evidence would need to be provided about the way the administration of the estate has been handled if the executor will not agree to stand down voluntarily.
