Local Procedures at the Circuit Court

Probate filings use the Fourteenth Circuit's approved probate forms, numbered P-1A through P-145, with inapplicable alternatives struck before filing. A filing that is not on an approved form or does not follow the rule needs leave of court. Every estate representative files an annual report or account, the first due by the first Monday of the month after one year from the issuance of letters and then on each anniversary until the estate closes. Each report gives the attorney's and representative's contact details, a schedule for closing the estate and any problems delaying it.
