Once you've decided that you need life insurance and how much, it's time to start shopping. Consider the financial health of the company you choose and be sure to re-evaluate the policy whenever you have a life-changing experience -- such as a marriage or the birth of a child.

Shopping for life insurance is tricky. You're buying a product that you might not use for several decades, so select a company that's in good financial shape. (Check out how A.M. Best Company rates the company.) To compare insurance policies and quotes, visit Insureme.com, a Bankrate company.

Some states supply consumer information or log complaints, which also can help with your decision. Try your state's office of insurance or consumer affairs.

If you work with a financial professional (for example, a CPA or a financial planner) who knows your situation but doesn't profit from selling insurance, ask advice on how much insurance you should carry and what type might be best for you.

Once is not enough

When you first married, you may have bought a policy that gave your spouse enough to pay off the mortgage. But 20 years later, you've traded up two houses, have a couple of teenagers heading off to college and your financial needs are different.

Who will benefit?
