Me and my sister are both beneficiaries of my dad’s will wear a house is concerned which I live in and have lived in she is the executor of this hous

Until your sister has actually offered your father's Will for probate and been formally appointed as the Executor of his estate by the appropriate probate court, she isn't the Executor of anything. First step, then, is to make sure whether that's already happened. Assuming that your father lived in Georgia at the time of his death, you, as one of his heirs, should have received notice that his Will was being offerered for probate and been given a chance to object. If the Will has been admitted to probate and your sister had the Letters Testamentary appointing her as the Executor, then she can take steps to evict you from the house. However, you have rights as a tenant if you were living there prior to your father's death and have not moved out. You need to find an attorney who can help you understand your rights as a tenant (these are separate from your rights as an heir and a beneficiary under the Will) to ensure that you are protected. You may have to move, but your sister shouldn't just be able to change the locks and dump you out of the house without some process. You may also want to hire an experienced probate attorney to help you understand your rights as a beneficiary under the Will. If your sister does not carry out her job correctly, your rights and interests could be damaged. You are entitled to hire someone to help you protect yourself. Best wishes to you and my condolences on the loss of your father.
