It has always been my understanding that any assets I hold jointly with my husband would go to him when I die. A few months ago, you printed a column that said if there was a plane crash and no way of determining who died last “each member of a couple who die together will be presumed to survive the other so both Wills would be followed”. What happens to joint assets in that scenario?

Under the Wills, Estates and Succession Act, the joint ownership is severed and your estates would each own 50% of each previously held joint asset outright.
