It's possible to find life insurance if you are 87 years old, but it may be difficult to qualify for a traditional policy. Age is a big factor in determining premiums, and since you are getting toward the end of life expectancy, the insurance company may consider you too much of a risk.
To try and find a policy, you'll likely have to shop around and compare different options. You may be able to qualify for a burial insurance policy or a whole life insurance policy that doesn't require a medical exam. These policies typically offer coverage of $10,000 or less and last until you pass away.
You could also consider a final expense insurance policy, which is designed to provide money to cover burial expenses. The criteria to qualify for this type of policy is usually more relaxed, so it might be easier to get coverage. Most policies cover between $3,000 and $15,000.
If you don't need a large death benefit and just want to leave money for your family, you could also look into setting up a trust that would provide a lump-sum payout when you pass away.
