Discovered my oldest brother fraudulently forged my deceased father's signature and sold my parents' property in Florida. What can I do?

Prosecute the SOB. There are far too many "family members" acting for elderly parents who literally steal an honest siblings inheritance. Sorry, your comment made me angry. Jeannegibbs is correct, we really do need more info. Question, did you want to purchase the property from the estate, or do you just want your share of the proceeds? How did he do this without a properly executed POA?

i know a guy doing 5 years in prison for one of these didos. now wheres that lady who was trying to make a federal case out of a few missing pills earlier?

Give us a little more information. Did you father leave a will? Who was the property to go to? What has your brother done with the money? Was your brother the executor of the will? Is he planning to divide the money among the heirs?
