The executor does not have any rights or responsibilities before the person dies. Being paid makes no sense and is not a legal right.
I get it.
It depends on who the home is willed to.
No, but if it is offered for probate, it will be public information.
No
No, the property was left to the son. What he does with it is his business.
If an heir of an estate dies who entitled to that portion of the money?
Social Security Death Benefits until age 18.
No. Until a testator dies their will is private and no one is entitled to access to it.
They may be entitled to a portion of his estate under the state laws of intestacy. You can check your state laws at the related question link below.
Not if the will says otherwise.
Of course, laws are different in different places and you should ask an attorney about the specifics of your situation. However, in general you are entitled to inherit from your sister-in-law if your brother dies before her only if your brother made a provision in his will that some of his estate pass to you after his wife dies, or if she includes a provision for you in her will.
Yes and No, it depends entirely on how the will is written and 'if' the person making the will wants to or not. Some people do not even know they are executors until after the person passes away.
