I recently had to deal with this here in the UK when selling my mother's house. She's 94, far into dementia and bed-bound, was a stay-at-home mom all her life. She had no photo ID of any sort, and since she'd been in a home for quite a while, no utility bills or any of the other things needed to prove identity in the modern world.

It took quite a while to work out something that would be accepted for the title transfer.
