Good day! My grandfather had 4 daughters. A few days ago, my mother and I learned that my great-aunt from America, when she was alive, left an inheritance to all her relatives from Ukraine. My question: How do I find out if my grandfather received an inheritance? The aunts do not say anything and keep everything quiet as they have been living with him for the last few years. Thanks in advance.
