How long would it take for your dependents to be come self-sufficient? If your children are almost out of college, they may not need much additional income. If they're younger, remember that dependent spouses caring for young children can usually return to work at some point, and some kids may get at least partial scholarships.

Once you perform this exercise, you may find that your dependents may need little additional income from life insurance. But if you have young children, you may find that it makes sense to buy an affordable amount of life insurance. For more information, see Using Life Insurance to Provide for Your Kids.

Short-Term Needs

Now, assess whether you need life insurance for short-term needs:

What assets will be available to take care of your dependents' immediate financial needs? You might leave some money in joint or pay-on-death bank accounts, or place marketable stocks in joint tenancy or register them on beneficiary (transfer-on-death) forms.

After you die, how long will it be before your property is turned over to your inheritors? If most of your property will avoid probate, there's usually little need for insurance for short-term expenses, unless you have no bank accounts, securities, or other cash assets. By contrast, if the bulk of your property is transferred by will, and therefore will be tied up in probate for months, your family and other inheritors may need the ready cash insurance can provide. While a probate court will usually promptly authorize a family allowance or otherwise allow a spouse or other inheritor access to estate funds, it can still be nice to have insurance proceeds available.

Will your estate owe substantial debts and taxes after your death? Lawyers and financial advisors call cash and assets that can quickly be converted to cash "liquid." If your estate has almost all "non-liquid" assets (real estate, collectibles, a share in a small business, jewelry), there may be a significant financial loss if these assets must be sold quickly to raise cash to pay bills, as opposed to what they could be sold for later if there had been enough liquid money from insurance or other sources to meet all pressing bills. Obviously, if your estate has significant funds in bank accounts or marketable securities, you won't need insurance for this purpose. Fortunately, federal estate taxes aren't due until nine months after death, so cash to pay them doesn't have to be raised immediately.
