An endorsement is an amendment or modification to a title insurance policy. Endorsements cannot be issued except in connection with a title insurance policy. Endorsements may increase the liability of the Company under the policy.

Endorsements, unlike title insurance policies, have only limited uniformity. There are land title association endorsements, such as the ALTA and CLTA endorsements, and endorsements filed by rating bureaus or promulgated in other states. However, many "scrivener" or specific endorsements also may be available on particular transactions, with underwriter approval. Stewart Title Guaranty Company, for example, has an array of endorsements available to both owners and lenders. Some endorsements, because of local custom, are exclusively used in certain areas and not in others.
