Definition - What does Disclaimer mean?
A disclaimer is a notification tool that individuals or companies use to try to limit their liability in relevant matters. Disclaimers generally tell customers or other people that the party involved is only responsible for certain aspects of the product, service, etc., and not liable for others. For example, a car dealership may give a disclaimer that a vehicle is being sold 'as-is.' This means they aren't liable for any problem that the new owner may discover after the purchase.
