I've had a will for several years now and updated it twice. I have to update it again due to the passing of my husband in December. But it's set up so that if an heir dies, his or her share automatically goes to my (or their) next in line. So now that my husband is gone, my son (not his biological child) gets his share and God forbid my son would predecease me, his share gets split evenly between his 5 children. I still want to revise my will again though. My son, his children, his wife, my honorary son (son's BFF who's so good to me), honorary granddaughter and my former DIL (also very good and like a daughter to me) stand to inherit money. Brokerages have their own beneficiary designations so distributing what's due heirs are through them. My bank accounts are payable on death (POD or TOD)...most to my son and one to his ex. There's a special will attachment that lets me name and update on my own, who gets certain of my personal belongings. My son, oldest grandson, y granddaughter, my DIL, former DIL, sister and 2 nieces are named there.
