The contract to be valid must be for the benefit of one having an insurable interest, otherwise the contract is a wager, which the law condemns. This is sufficient if the person taking the insurance has such an interest arising from his relation to the insured as creditor and surety, or from the ties of blood or marriage that will justify a reasonable expectation of advantage or benefit from the continuation of his life. It is not needful that this expectation or benefit should possess a pecuniary valuation. The mutual legal rights and liabilities of father and minor child are sufficient to create an insurable interest on the part of each in the life of the other; also the relationship of brother and sister, and that of husband and wife. Likewise a man and a woman who are engaged to be married; and a creditor has an insurable interest in the life of his debtor. And this interest covers not only the amount of the indebtedness, but also future advances, and the cost of taking out and keeping up the insurance. A partner who has advanced the capital of the business has an insurable interest in the life of his partner. More generally any person who invests money relying on the efforts of another to produce a return has an insurable interest in such person's life. A surety therefore has an insurable interest in the life of his principal; an executor in the life of a person who has granted an annuity to the testator; a common carrier even may insure against loss from injuries to passengers. But the relationship between uncle or aunt, nephew and niece and that of cousin is not sufficient to support a policy taken by one in the life of the other.
A policy may be assigned to one who has no insurable interest if made in good faith, and not as a cloak for the procuring of insurance by one having no insurable interest. This rule does not prevail everywhere, but the courts which do not accept this rule usually protect the assignee who has paid the premiums to the amount of his payments, while the estate of the insured takes the balance that may come from the insurer, whenever the assignment of the policy is not invalid. An assignment to one who has an insurable interest as relative, creditor and the like, is always valid.
A general agent, says Justice McClain, "may bind the company by an agreement as to rate of premiums, or other terms of the contract, even as against the express provisions of a policy subsequently issued, there being no negligence on the part of the insured in failing to advise himself as to the terms of the policy; but if the want of authority of the agent to vary the terms of the application is brought home to the applicant, oral communications of the insured to the agent are not to be considered in determining the validity of the insurance. If the agent has exceeded his authority as to the terms of the proposed contract, the company cannot reject that part which the agent was without authority to make and enforce the rest, but must accept or reject in toto."
Until a proposition for insurance has been accepted by the company there is no contract. Delay in accepting an application which is subject to approval does not effect an acceptance. There may be a binding contract of insurance as soon as the company has accepted the application, or on the delivery and acceptance of it by the company's agent, when he has authority to do so. In order to complete the contract before issuing the policy there must be an agreement to this effect, and before the death of the applicant. The receipt by an agent for the first premium, or of a note therefor, subject to the approval of the application by the company, does not effect a contract between insurer and insured.
Some states have enacted statutes prescribing requirements for life insurance policies, or standard forms. Delivery to a third person for the insured may be sufficient. The contract becomes complete when the policy is put in the mail, postage prepaid, for delivery in due course to the insured. Delivery to the insured for examination of course does not effect any engagement on the part of the insurer, nor does a delivery on condition.
It is often stated that the delivery shall not be effectual to create a contract unless the insured is alive and in good health when the policy is delivered and the first premium is paid. Indeed, how could it be valid if the insurer is dead? And if the contract is with a person other than the insured as beneficiary, it would be void on the ground of mistake. Likewise, under such a condition, a policy does not become effective, without a waiver, if the insured is in ill health at the time of its delivery or payment of the premium.
Unless waived by the company, there is usually a stipulation to the effect that the company shall not become bound until the first premium has been actually paid and accepted by the company or its authorized agent. But if the premium is actually paid by the agent of the company for the insured by virtue of an agreement between them, this will bind the company. The payment of the premium by a third person without the knowledge of the insured does not have the same effect.
A general agent has authority to waive the stipulation, that the policy shall not take effect until the first premium is paid, though of course he may be restricted in this regard, but a special agent cannot waive this stipulation; though if he acts otherwise and the company ratifies his act, it is bound. A provision also that a policy shall not be valid unless the premium is paid when the insured is in good health may be waived by an agent who has authority to take applications, collect premiums and deliver policies.
Passing to the nature of the contract, if made in violation of a statute, or if contrary to public policy and this is known by both parties, it is void. Thus a stipulation that a policy shall be payable though the insured may be executed for a crime is contrary to public policy and is therefore void. The same is true of a stipulation insuring against death by suicide while sane. It is against public policy to allow one person to have insurance on the life of another without his knowledge. A policy issued on a person beyond a specified age is prohibited by statute.
What is the effect of fraud in negotiating and issuing policies? If the company or its agent perpetrates a fraud whereby one is induced to take out a policy, he can at his option declare it void, unless so negligent in acting as to work an acquiescence of it. But if acting in a proper way and time he can set up fraud as a defense in an action to get the premium for which the contract has stipulated; or he may sue to have the policy declared void and his premiums returned to him; or he may bring an action against the company or its agent, or both, to recover the damages he may have sustained by the fraud that has been practiced on him.
