Second-to-Die Policy
A second-to-die life insurance policy, also called survivorship life insurance, covers two lives — typically a married couple — and pays the death benefit only when the second insured person dies, making it a cost-effective tool for estate planning and wealth transfer.
Under federal estate tax law, assets passing between spouses at death generally qualify for the unlimited marital deduction, meaning no estate tax is due when the first spouse dies. The estate tax liability crystallizes when the surviving spouse dies and the combined estate passes to the next generation. A second-to-die policy is specifically designed to match this liability timeline by paying out at the second death — exactly when the funds are needed.
Because the policy does not pay until the second insured dies, the insurer bears less immediate mortality risk compared to individual coverage on a single life of the same age. This lower risk translates into lower premiums relative to two separate single-life policies. The premium savings can be substantial, particularly if one spouse has health impairments that would make individual coverage expensive or unavailable, since the underwriting risk is shared across two lives.
Second-to-die policies are almost always held in an Irrevocable Life Insurance Trust (ILIT) to exclude the proceeds from both spouses' taxable estates. Without the ILIT structure, the death benefit might be included in the survivor's estate when they die, defeating the purpose of the arrangement.
Beyond estate tax liquidity, survivorship policies are used to fund charitable bequests, provide inheritance equalization when one heir inherits a business or illiquid asset, fund special needs trusts for a dependent child, and create wealth for subsequent generations.
When both insureds are relatively young and in good health, the long expected policy duration allows for substantial cash value accumulation, which can be accessed if circumstances change and the policy is no longer needed for its original estate planning purpose.
