Setting up a trust on your deathbed would see HMRC ignore the trust.
However for the purpose of this thread s102 Care Act 2014 is relevant, and places the cost burden on the life tenant of the trust.
Apropos of your final point, most trusts have provisions for either new beneficiaries or the termination of the trust and who are absolutely entitled to the assets.
