Title insurance is a form of indemnity insurance predominantly found in the United States which insures against financial loss from defects in title to real property and from the invalidity or unenforceability of mortgage loans. Title insurance is principally a product developed and sold in the United States as a result of an alleged comparative deficiency of land records in that country. It is meant to protect an owner's or a lender's financial interest in real property against loss due to title defects, liens or other matters. It will defend against a lawsuit attacking the title, or reimburse the insured for the actual monetary loss incurred, up to the dollar amount of insurance provided by the policy. The first title insurance company, the Law Property Assurance and Trust Society, was formed in Pennsylvania in 1853. The vast majority of title insurance policies are written on land within the United States.
Typically the real property interests insured are fee simple ownership or a mortgage. However, title insurance can be purchased to insure any interest in real property, including an easement, lease or life estate.
