Title insurance premiums are not principally calculated on the basis of actuarial science, as is true in most other types of insurance. Instead of correlating the probability of losses with their projected costs, title insurance seeks to eliminate the source of the losses through the use of the recording system and other underwriting practices. As a result, a relatively small fraction of title insurance premiums are used to pay insured losses. The great majority of the premiums are used to finance the title research on each piece of property and to maintain the title plants used to efficiently do that research. There is significant social utility in this approach as the result conforms with the expectations of most property purchasers and mortgage lenders. Generally, they want the real estate they purchased or loaned money on to have the title condition they expected when they entered the transaction, rather than money compensation and litigation over unexpected defects.
It is important to note the maximum liability of a title insurer is limited by the face amount of the title policy regardless of any appreciation in the value of the real property occurring after the issuance of a title policy.
