When my grandpa died, my dad took my grandma to get all the bank accounts changed over to her name and a new credit card, since the card she had been using basically all of her adult life was in my grandpa's name. The bank originally wouldn't give her one. At that point my grandma was 75, never had an actual job or any reportable income, her name was never on the mortgage, a car loan, credit card, cell phone, phone bill, nothing. Zero credit history.
Took some convincing by the bank manager to someone at Visa to get her a card - "She's got $xxxK sitting in her account, she'll pay it, don't worry!"
