New Florida Statutes §732.806, which is effective October 1, 2013, makes an improper gift to a lawyer in a will or other estate instrument void.
The new statutory provision is here: http://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0732/Sections/0732.806.html
The new Florida statute in effect tracks 4-1.8(c), Rules Regulating The Florida Bar and incorporates it into the probate code, and makes a violation of the statute a basis for voiding any part of a will, trust or other written instrument which makes an improper client gift to the drafting lawyer or a person related to the lawyer. The statute also provides exceptions to this prohibition, including gifts where the lawyer or other person is related to the person making the gift as well as title to property acquired for value from a person who receives the property which violated the statute.
