Sapata has an ordinary life insurance policy on her life and a fire insurance policy on her house. Both policies have been in force for a number of years. Sapata’s life insurance names her son, Rory, as beneficiary. Sapata has specifically removed her right to change beneficiaries, and the life insurance policy is silent on the right of assignment. Sapata is going on a one-year European vacation and borrows money from Leonard to finance the trip. Leonard takes an assignment of the life insurance policy as security for the loan, as the policy has accumulated a substantial cash surrender value. Sapata also rents out her house to Leonard and assigns her fire insurance policy to him. Discuss fully whether Sapata’s assignment of these policies is valid.
