Life Insurance is a contract. As part of that contract, the owner of the policy designates beneficiaries, and the insurance company pays those beneficiaries per the contract. Normally, if the son is not the beneficiary, the insurance company will not pay the son, only the beneficiary. Insurance is not normally part of the estate.
However, you mention that there is no will. By law, without a will, the son may be entitled to a portion of the estate. Without a will, the estate would not normally go entirely to the wife. Contact a local attorney immediately to discuss this issue.
