With the way families are set up these days, I think it's very important to allow either the primary or the secondary parent access to the Financial details for an account. Often, one parent (e.g. the mother) will take the lead on arranging time and care for a child, but the other parent (e.g. the father) will pay the account. It's important to allow both parents on an account access to review and pay outstanding amounts and set up direct debits.
