What is a presumption of undue influence in the state of Florida?

In Florida, the presumption of undue influences occurs when an individual contesting a will can demonstrate three key factors: firstly, that the individual who applied the undue influence is a significant beneficiary of the estate planning documents; secondly, that the individual who applied the undue influence had a confidential relationship with the person who signed the estate planning documents; and finally, that the individual who applied the undue influence actively participated in obtaining the estate planning documents.
