Florida Probate RULE 5.440, provides the process to remove the personal representative of an estate as follows:

• (a) Commencement of Proceeding. The court on its own motion may remove, or any interested person by petition may commence a proceeding to remove, a personal representative. A petition for removal shall state the facts constituting the grounds upon which removal is sought, and shall be filed in the court having jurisdiction over the administration of the estate.
• 
  
• (b) Accounting. A removed personal representative shall file an accounting within 30 days after removal.
• 
  
• (c) Delivery of Records and Property. A removed personal representative shall, immediately after removal or within such time prescribed by court order, deliver to the remaining personal representative or to the successor fiduciary all of the records of the estate and all of the property of the estate.
• 
  
• (d) Failure to File Accounting or Deliver Records and Property. If a removed personal representative fails to file an accounting or fails to deliver all property of the estate and all estate records under the control of the removed personal representative to the remaining personal representative or to the successor fiduciary within the time prescribed by this rule or by court order, the removed personal representative shall be subject to contempt proceedings.

The proceeding to remove is similar to a divorce action. It is heard entirely by a judge, and requires a trial concerning the personal representative's acts and omissions. If the petitioner proves that the personal representative has been misappropriating funds, then the court will order the appropriated assets returned. If the assets are already wasted, then the court can award damages against the personal representative, in the amount of the wasted assets. Additionally, a new personal representative will be appointed.
