And hope the old bag doesn't live long enough to use up her money, that she doesn't leave a chunk of whatever is left to charity, or directly to all her grandkids, or to a trust. Or that she doesn't have medical and nursing home bills plus burial expenses that equal the estate value. If his dad is still alive, everything could go to dad. if there is anything. In other words, don't start counting on Grandma to payoff the arrearage. If you are liucky and there is an estate of some value, and if she leaves a chunk to sonny boy, and if she hasn't racked up medical and nursing expenses, it may work out.
