Legal Question in Wills and Trusts in Florida

Since she died without a will, according to Florida State Law, it will pass per stirpes, which means her next of kin, which is you. Without seeing the power of attorney you have, I cannot say whether you can administer her estate. That has to be done by a personal representative, which the court will appoint since your mother did not leave a will appointing one. It seems you and your mother will need to fight it out in court. I suggest you see a probate attorney as soon as possible.
