We reverse and remand the trial court’s order which reaffirmed the final judgment of adoption. The so-called “consent” was neither properly sworn nor executed within the presence of the notary. It contained an acknowledgment, not a jurat, as required in a sworn document. See Neff v. Adler, 416 So.2d 1240, 1241 n. 2 (Fla. 4th DCA 1982).
