There is a form you can use here:http://www.doh.state.fl.us/planning_eval/vital_statistics/DH...
I usually just send a letter with my name, address and phone #, along with name, exact date of death, county and file # if I have it. If death is more than 50 years ago, you will get cause of death. If it is less than 50 years, ago, you can get cause of death, but will have to provide relationship and photocopy of your driver's license. If less than 50 years, I would use the form so they can easily see what you need.
