Prepare the four documents
1) Affidavit of Default
2) Motion of Cancellation
3) Order of Cancellation
4) Certificate of Service

* It also appears under Rule 1.500, Defaults and Final Judgments, per the Authors' Comment--1967 in F.S.A., that the Soldiers' and Sailors' Relief Act of 1940, 50 U.S.C.A.App. § 520, requires that, upon a default, an affidavit to the fact of whether or not the defendant is not in military service. (That seems reasonable, to protect someone unavailable to make an appearance because he's overseas somewhere, so he he does come back to find he's lost property in a civil process while he was gone.) There are two forms for this: a "Memoradum For Certificate of Military Service," with which to request this information from six military establishments, and then a "Nonmilitary Affidavit." These can be purchased from your local court clerk. The instruction from the Authors' Comment reads in part:

"Under the Act, which applies to both federal and state courts, before a judgment based upon a default by the defendant may be entered, the plaintiff must file either: (1) an affidavit setting forth facts showing that the defendant is not in the military service, or (2) an affidavit setting forth that the defendant is in military service or that the plantiff is unable to deetermine whether or not the defendant is in such service."

See noted on making a NonMilitary Affidavit.

Also include a SASE to mail the signed order or cancellation (copy) back to you...
