No-one likes to think about the worst that could happen. But proper life insurance cover could protect your family, providing them with the means to cope financially should you pass on. Life insurance cover is divided into three main types. Here is our jargon-busting guide to de-mystifying what they are, and what they mean:

· First we have the level term policy. This pays a one-off cash payment when you die. The amount is agreed when you take out the policy and does not change.

· An increasing term policy is also known as indexed insurance and the amount paid out changes with inflation. Some policies of this type may have premiums that rise with inflation too, but some do not.

· Lastly a decreasing term policy pays out an amount on death that decreases through time, getting smaller as the policy progresses. A long-lived customer may even outlive the point where the policy pays anything at all.

These policy types often form part of loan or mortgage deals. There are benefits to each type, depending on the loan or mortgage it is being used to safeguard.

Level term policies are most usually used with interest only mortgages. This type of mortgage does not reduce the capital you borrowed with time – you only pay off the interest. When you die, the capital amount is paid off by the insurance policy payout. Whatever may happen with inflation, it does not change.

Increasing term policies cost more, but offer protection against inflation.

Decreasing term policies are usually used with repayment mortgages. In this type of mortgage the capital is paid off along with the interest, decreasing the amount you owe. This type of insurance has lower premiums than level term insurance.

Term policy payments can be settled in two ways: either as a single or “lump” sum, or as “family income benefit”. This second method means that an agreed amount is paid to your family as an income for the remaining duration of the policy. The method you use affects the cost of the premium you will have to pay. If you consider that the longer a policy holder lives, the fewer family income payments an insurance company will have to make, you can see why this type is cheaper.

So far, we have only discussed insurance for mortgages and loan payments. These are both useful, but there are other things you can do to ensure peace of mind.

A typical, average family, it is estimated, will need insurance for both parents worth at least £150,000 in insurance for each child, in addition to any death-in-service benefits you may expect ( these usually come with your employment). Taking the option of family income benefit, it's recommended that you should allow for an income of £20,000 to £25,000 a year for each child.

There is another alternative form of life insurance. It pays out a guaranteed sum on the death of the policy holder (the sum assured), and is known as whole of life. The terms for this type of insurance vary.

You can also buy life insurance bundled with your pension fund. This gives you the opportunity of getting tax relief on the premiums you pay. A higher rate tax payer can get £100 worth of life insurance for only £60, which makes this an attractive method to some. On the downside, higher administration costs for this type mean higher premiums overall, so basic tax rate payers may prefer to shop around and compare to make sure they get the best deal.

Some couples take out a joint policy covering both at once, but it's better to take out individual insurance. The reason for this is that a joint policy pays out only once, when the first partner dies, but individual policies pay out for each partner.
