To ensure annual returns from every personal representative, it shall be the duty of the probate court to keep a docket of all those who are liable to make returns and, immediately after the ceasing of the January term or as soon thereafter as the court deems practical in each year, to cite all defaulters to show cause for their neglect. A willful and continued failure to make a return shall be good cause for removal.
