Combination and survivorship life plans

One Contract, Two Lives

Most life policies insure one person. A few plan designs put two or more people on a single contract and then make the payout depend on the order in which those people die. Two of them carry this objective: the joint life plan, sold as first-to-die and often marketed as a combination plan, and the survivorship life plan, sold as second-to-die or last-survivor.

Everything else about these products follows from one question: which death releases the money?

Joint Life (First-to-Die)

A joint life policy covers two or more insureds and pays the full face amount the first time any one of them dies. It pays once. The contract then ends, and the surviving insureds have no coverage left under it.

The pricing follows from that single obligation. Two individual policies on the same two people represent two full death benefits the insurer may eventually have to pay; a joint life policy represents one. That is why the joint premium lands below the combined cost of two separate policies at the same face amount -- not because the insurer expects to pay later, but because it only ever pays once. In fact it expects to pay sooner, since the first of two deaths arrives earlier than either death considered on its own.

The classic use is a buy-sell agreement. Two co-owners agree in advance that when one of them dies, the survivor will buy the deceased owner's share from the estate. The survivor needs cash at the first death -- which is exactly when this policy pays.

Survivorship Life (Second-to-Die)

A survivorship policy insures two people and pays only after both have died. The first death produces no benefit whatsoever; the policy simply stays in force, and premiums generally remain due until the second death.

Deferring the payout to the later of two deaths pushes the insurer's expected payment date further out than either life's alone. That is why survivorship premiums typically run below the cost of two individual policies, and why they can undercut even a single policy on one of the two insureds. The same logic drives an underwriting quirk worth knowing: because the benefit never depends on any one insured dying, an insurer may issue survivorship coverage when one of the two proposed insureds is rated, or is uninsurable on their own.

The classic use is estate liquidity. Property passing to a surviving spouse generally escapes federal estate tax at the first death through the marital deduction, so the tax bill, where there is one, lands at the second death. A survivorship policy delivers cash at precisely that moment, rather than leaving heirs to sell an illiquid asset -- a family business, a farm, real estate -- to raise money on the government's timetable. These policies are frequently owned by an irrevocable life insurance trust, so that the proceeds fund the tax instead of enlarging the estate that generated it.

Combination Plans in the Broader Sense

"Combination plan" is also used more loosely for a contract that blends coverage types rather than lives -- most often a family plan, in which permanent insurance on one adult carries term riders covering the spouse and the children. One contract, one premium, several coverages each sized to a different job.

Insurable Interest Still Applies

Putting two lives on one contract relaxes nothing about insurable interest. Each insured must be tied to the others by an interest the law recognizes at the time the contract is made: spouses and close family by blood or marriage, co-owners by the buy-sell contract they have with one another. That requirement is what makes these designs available to couples and business partners, and unavailable to strangers pooling a wager on each other's lives.
