You don't buy and estate. An estate is created after death. Yes, there is an estate and it will be distributed according to the laws of intestacy in the state or country in question.
It is a bit hard for anyone other than the estate to cash the checks, so yes, they are reported to the estate.
They do not, however, they cannot inherit anything until the estate has resolved all debts.
No one automatically has any rights to the decedant's property. If a person dies without a will they are said to have died "intestate." In that case the decedant's estate will be probated by the court and divided according to court order.
Was this property bought before or after marriage? Either way, if you are married and want to sell real estate or a car or such, both spouses have to sign their consent to the transaction. So if your husband sold something behind your back, you might have a case. If it was bought before that, there's room for argument.
The executor should never pay the bills themselves. They should have the estate do it. Yes, with proper receipts, there should be no problem with getting the money back.
The estate is responsible for the decedant's debts. You should consult a probate attorney and open an estate to settle any debts and distribute assets, even if you don't think there are any assets, you might be surprised.
If the decedent owned any property at the time of death that property makes up her/his estate. If they had no will the property will be distributed as intestate property according to the laws of intestacy in the decedent's state. Some qualified person must petition the probate court to be appointed the administrator of the estate. Once they have been appointed they will have the power and authority to settle the decedent's estate under the supervision of the court. The decedent's debts must be paid before any property can be distributed to the heirs.
A living trust is set up for a specific purpose, with rules for what is to be done with the assets while the individual is living. They key to many is that it can also transfer the contents without going through probate. An estate is the property of a decedant that is going through probate.
It would go to his spouse
Marriage may have an effect on land ownership depending on your state or country. You should consult with an attorney in your area to determine the effect of local laws regarding marriage and real estate.
In the absence of a will, the property passes according the rules of intestate succession in the state the spouse died in. As far as I know, every state gives the estate to the surviving spouse, or the spouse and children in some proportion. Any will executed before the marriage is null and void as of the date of marriage, though you should consult an estate attorney on that state.
In order to file anything on an estate, for anyone's sister or kids, is to talk to a lawyer. If the husband will not give them back their things, after 2 years of marriage, he could be forced to by the law.
