For most people, the answer to this question is yes. If you have children or other people that depend on you, life insurance can provide for them after you pass away, so they can continue to maintain a good quality of life or pay the rent.
Even if you are not the breadwinner in your household, you may still need life insurance to protect your children and family. Consider how much your household budget would need to stretch to pay for services such as childcare if the stay-at-home partner died. Life insurance can cover these costs, allowing the family to carry on as normally as possible.
As life insurance can be very important for protecting your family, you need to carefully consider your needs when buying a policy. Always select a life insurance policy that will give your family enough money to live comfortably if you pass away.
In general, you should buy life insurance if you have people in your life that depend on you and your income, or if you want to preserve your wealth for future generations.
