My stepfather passed away before he could divide money from my mother's passing amonst her children. Her will stated a 50/50 split deaths 90 day apart

My mother left a will stating that she wanted any money made available in her passing to be divided equally between her husband and her children 50/50 split. While he was collecting the money to be divided he fell ill from Covid and passed away before he could honor her wishes and divide the money. He also died without a will is there anything my siblings and I can do to recover this money
