If your father left the home to you in a Will and it does not need to be sold to pay his debts, the executor of his Will should record a Distribution Deed into your name. If your father did not leave a Will and your brother has been appointed by the court to be administrator of your father's estate, it is his duty to evict you in order to sell the house, pay the debts and distribute what remains according to the state's laws of inheritance.
