The trial court’s findings that appellee overcame the presumption of undue influence by coming forward with a reasonable explanation for her active role in the testatrix’s affairs, especially in the preparation of a new will, is supported by competent and substantial evidence and thus, will not be disturbed. See In re Estate of Carpenter, 253 So.2d 697 (Fla. 1971); In re Estate of Blakey, 363 So.2d 630 (Fla. 3d DCA 1978).

Affirmed.
