When it comes to buying a life insurance policy there's no set age limit that the insurance companies have to follow to sell you a life insurance policy.
However most life insurance companies set an age limit as to when they will sell you a life insurance policy.
The age limits for life insurance policies is between ages 70 to 85 years old.
So it's best to get life insurance if you need it well before 70 years old because it takes a few years of having the life insurance policy before they will actually pay out upon your death.
So you want to get the life insurance while you're 50 years old or younger if possible to allow a lot more time to get the insurance policy built up so they will pay out upon your death.
If you have no family that needs the money to pay your bills etc then you only need to either pay your funeral or have burial insurance.
