Recently the 3rd DCA in the Florida case of Lorenzo v. Medina ruled that the anti-lapse statute must be strictly construed and that gifts to in-laws are not saved and lapse unlike a gift to a close family member.
This means a gift to a sister-in-law who predeceases the testator is not honored while a gift to a predeceased sister would go to her children. If you are involved with trying to save assets for the families of non-relatives you should talk with a Florida Estate Planning Lawyer how simple changes to your Florida Will or Florida Revocable Trust can ensure that your intentions are carried out.
