If there is someone who would suffer economic hardship if you died, then the answer is yes... you need life insurance! Families with young children have a clear need for life insurance. If both spouses work, the loss of one income will cause the family immediate economic hardship and make it harder for them to realize future goals, such as paying for the children's' education. But even if one spouse works "inside the home" and doesn't bring in a formal income, his or her death will require the surviving spouse to hire child care, housekeepers and other professionals to help run the household - and that can be a significant new expense.
If you are married without children or single, then you may need life insurance to protect your partner or surviving family members against the costs associated with your death. Funeral expenses, probate and administrative fees, outstanding debts, special obligations to charities, and federal and state taxes are costs that all of us must consider. And, they can add up quickly. Unless you already have sufficient financial resources, your survivors will probably need life insurance to cover these expenses.
