To answer this question requires details you didn't provide. What do you mean by "inherit" the IRA. If he's listed as the beneficiary on the IRA, that's one thing. If he isn't, but you are assuming your husband is listed as the heir in the will (or he's the only possible heir if the parent died intestate), then that's a different thing entirely. Presumably there's something else in the estate other than the IRA? What does the attorney handling the probate say?
