This would especially be true if the cause of your death was something that you lied about on your application when applying for the life insurance.
The life insurance company usually returns all the premiums paid in, but will not pay the death benefit, in cases where the cause of death of the insured person was lied about on the application during the contestable period.
This means, if for instance, you say on the application that you don't smoke and have never smoked, then you get insured, and 18 months later you die from lung cancer as a result of smoking, the insurer will likely not pay out a claim on your life insurance policy because the lie was a material misrepresentation that would have impacted how your life insurance application was underwriter, rated, and approved or turned down for coverage.
