For inheritances in the United States, the laws of each state establish who owns the assets of a person after their death. Or, to me more precise, who acquires the ownership of the real estate, money, rights and debts of the deceased, and in what percentage.
However,
there are legal aspects that apply to the entire country and principles that
must be known, such as the types of will, the rights of the spouses and
children, succession rules and applicable taxes.
