You will need to contact an attorney in your area who specialised in probate law. They will be able to assist you in determining who the property belongs to.
Yes, a half sister can share in her fathers estate if she was the blood daughter of the father.
No. It doesn't belong to your sister until the estate distributes it. The estate will split the money/value as directed by the will or the intestacy laws. You will get your share and your sister will get her share. The IRS can place a lien on her share.
Upon your father's death, his half of the joint bank account would typically pass directly to your sister as the surviving account holder. It would not be included in his estate and would not go through probate.
If your father is deceased, it is a refusal to accept any proceeds.
You need to speak with an attorney who can provide the specialized legal advice you need in this situation. Your sister is an heir and is entitled to her share of the estate by law. However, if she is receiving any government benefits that share may change her status. She may lose benefits and need to reapply until her inheritance is depleted. If done properly, your father should have left her share in trust to keep it out of her own estate. There are many different legal aspects to your situation and you need to consult with an attorney who specializes in such matters ASAP.
The property is now part of your sister's estate.
Your sister has no power to sell any property your father devised to you in his will. A power of attorney is extinguished when the principal dies. If she had a power of attorney for your father it is no longer effective. Real estate must pass through probate in order for title to pass to the heirs. She has no authority to sell real estate unless she has been appointed the executor, the will gives her the authority to sell the real estate or the court has granted her a license to sell the real estate. You should seek the advice of an attorney, especially if real estate is involved.
If your father died intestate then his property passed to his next of kin according to the laws of intestacy in the state where he lived. If you and your sister were his only next of kin then you each would inherit a half interest in his property both real and personal. However, in order for title to real estate to pass to the heirs his estate must be probated. If you were the court appointed administrator of your father's estate you would need a license from the court to make any changes in the ownership of the real estate. If you obtained a license from the court to transfer the property to your name and your sister assented to that license then it's too late for her to change her mind. However, if the estate was not probated and you had no authority and license to transfer title then all your sister needs to do is petition the court to be appointed administrator of the estate. Any actions you took regarding the transfer of title would be null and void due to your lack of authority. When a person dies and there is real property or solely owned accounts in the estate an attorney who specializes in probate law should be consulted to initiate a probate proceeding. The average person has no background in probate law and errors made by a non-professional can be costly down the road.
