The Court always has the inherent right to modify child support based on the Florida Child Support Guidelines, despite any prior agreement of the parties to the contrary, including prior agreed upon deviations. A settlement agreement cannot divest the Court of jurisdiction to modify child support.
See Guadine v. Guadine, 474 So. 2d 1245 (Fla. 4th DCA 1985).
