If insurance benefits are paid to a beneficiary who does not have an insurable interest, that beneficiary holds the proceeds for the benefit of those entitled by law to the proceeds according to a 1894, Texas Supreme Court opinion styled, Cheeves v. Anders. This proposition was upheld in a Tyler Court of Appeals opinion from 1998, styled, Stillwagoner v. Travelers Insurance Co.
An insurer that knows of an adverse claim but pays the proceeds to someone without an insurable interest may be liable to the proper beneficiary or to the insured’s estate for the full amount of the benefits.
While Texas law requires that the designated beneficiary have an insurable interest, it is not essential to the validity of the contract, and the insurance company may not raise the beneficiary’s lack of an insurable interest as a defense of payment. When an insurer issues a policy to someone without an insurable interest, the insurer must pay, and the law will decide who gets the proceeds. This is also from the Cheeves case and the Stillwagoner opinions.
