This is a common question with many factors to consider. The first thing you need to determine is if your insurance policy covers dependents. Most insurance policies have language that specifically exclude coverage for parents. However, some insurance policies have language that will provide coverage for parents if they are financially dependent on the policyholder.
If your insurance policy does not cover dependents, you may be able to purchase a rider that would cover your parents. A rider is an add-on to your insurance policy that provides additional coverage. Riders are typically more expensive than a standard insurance policy, so you would need to weigh the cost of the rider against the cost of buying a separate insurance policy for your parents.
Another factor to consider is whether or not your parents live with you. If they do not live with you, they are not considered to be financially dependent on you and would not be covered under your policy.
If you have questions about whether or not your parents can be covered under your insurance policy, you should contact your insurance company or agent for more information.
