What do I need to demonstrate in order to prove lack of ability?

In the state of Florida, the examination to determine mental capacity for signing estate planning papers consists of three parts. First, the individual must comprehend the rightful beneficiaries of their assets, which includes knowing and recognizing their family members. Second, the testator must have knowledge and comprehension of their property’s nature and extent. Lastly, the testator must comprehend the practical consequences of the estate planning papers. If the testator fails to understand any of these factors, or fails to understand at least one of the three factors, then the document may be declared invalid.
