I want to contest a will in Bradenton, FL., I live in Lakeland. FL

Will drawn up by parents in 2003; since then mother and father both became senile before death; sister present at will, named executor and only she knew content. Parents told us there was $100k life insurance policy and house, divided 1/3, sister, me, brother.. Parents became senile, sister took over their affairs and somehow the life insurance payments stopped being made and she said it would cost me $3k to get it going again; I didn't have the money. Turns out sister lied to us all along, that she gets the house and we forfeited the life insurance cos we didn't pay for it. My brother died 2 weeks after my dad, and she has claimed his inheritance and his possessions. There was also $20k in cash, which she had already spent $4k, which was to be divided 3 ways; and a vehicle and jewelry. The jewelry disappeared; she claimed the vehicle which is in her name even tho dad made the payments and insured it, etc., and has refused to divide the cash in half, rather claiming 2/3.
