If you could even find that paper [marriage certificate] anymore, after decades and many moves.

Might want to keep it in a known (to you, to spouse, to responsible child) location. Some institutions, viz., brokerages and banks, want to see proof of spouse-hood to take control of a newly-deceased spouse's account; these institutions accept the marriage certificate as proof enough.
