If Patrick takes out a life assurance policy on the life of his wife, Emma, what is this policy called?

When an individual takes out a life assurance policy on someone else's life, such as a spouse, this type of policy is referred to as "life of another." This designation clearly indicates that the policyholder, in this case, Patrick, has a financial interest in the life of the insured person, Emma, which is a requirement for such a policy to be valid. This type of policy is essential because it provides the policyholder with the ability to receive a death benefit should the insured pass away, thereby protecting their financial interests.

The other options do not accurately describe the nature of the policy in this scenario. An "own life" policy pertains to coverage on the policyholder’s own life, while "joint life" refers to a policy that covers two people, usually providing a payout upon the death of one. "Dual life" is not a standard term used in life insurance and can create confusion, as it isn't widely recognized or utilized in practice.
