The format is the same as for any motion. Case caption at the top, style of case (case parties) case number, title of motion - then state your reasons. At the end there is your signature above your address block; and a certification stating that you sent the motion to opposing party/ counsel. The statute states the following:
1.540(b) Mistakes; Inadvertence; Excusable Neglect; Newly Discovered Evidence; Fraud; etc.
On motion and upon such terms as are just, the court may relieve a party or a party’s legal representative from a final judgment, decree, order, or proceeding for the following reasons: (1) mistake, inadvertence, surprise, or excusable neglect; (2) newly discovered evidence which by due diligence could not have been discovered in time to move for a new trial or rehearing; (3) fraud (whether heretofore denominated intrinsic or extrinsic), misrepresentation, or other misconduct of an adverse party; (4) that the judgment or decree is void; or (5) that the judgment or decree has been satisfied, released, or discharged, or a prior judgment or decree upon which it is based has been reversed or otherwise vacated, or it is no longer equitable that the judgment or decree should have prospective application. The motion shall be filed within a reasonable time, and for reasons (1), (2), and (3) not more than 1 year after the judgment, decree, order, or proceeding was entered or taken. A motion under this subdivision does not affect the finality of a judgment or decree or suspend its operation. This rule does not limit the power of a court to entertain an independent action to relieve a party from a judgment, decree, order, or proceeding or to set aside a judgment or decree for fraud upon the court.
