The point is, do it slowly and gently so he'll understand you need to know these things and won't feel like you're trying to take over. Then when he starts to have diminished capacity, you'll be in a position to gently challenge his decisions and, if necessary, take the real decision making away from him.
This is something all couples need to think about. A person who handles all the family finances can die suddenly in an accident when they're 25 and leave their spouse helpless and baffled because they don't know what needs to be done or how.
