Wills

I have a sister who passed away leaving four daughters. She has full brothers and sisters. She made a verbal will leaving the inheritance to her daughters. What is the ruling of Islamic law concerning this will and how is the estate to be divided?

My mother made a bequest in which she directed that her land is to be divided up equally among her sons and daughters. Is this bequest permissible?

Before my husband passed away, he bequeathed to me an apartment and a store in a five storey building which he had erected. The bequest was notarized. Am I entitled to take this bequest and am I entitled to inherit in my husband's estate?

Before passing away, my husband instructed his son that I am to receive his cash money upon his death. He repeated this on many occasions in public and many of our acquaintances know of it. I used to work and give my earnings to my husband who would put the money in the bank. What is the ruling for this?

My father passed away leaving a wife and children. He left a notarized property which he had bequeathed to all of his heirs except one son who, unlike the other heirs, had taken many things from his father during his lifetime. The father wanted the estate to devolve on the other heirs for the sake of equity. Is this will valid?
