dont assume anything. My life insurance policy, for example pays out a reducing sum and will pay out on my death, if it is in the next 21 years. If i do die, that money will be distributed as per my will, not to a named beneficiary of the policy. The money will be paid to my estate. If i then wanted to leave it to the cats home, i could. If i wanted to stop paying this policy at any time over the next 21 years i could, but i wont get anything from it. That is just 1 type of LI policy (bear in mind it becomes less valuable with a reducing payout every year)
The only person who can change or "cash in" a LI policy the named person isnt it?
