A home is often the largest single investment any of us ever make. Title insurance protects against loss of value from defects that may exist in the title, or arguments made by others that such defects exist. These defects or problems include fraud, forged signatures on deeds, unknown heirs or previous owners, liens and documentation errors. If you were uninsured and your right to the title is challenged, you could lose significant money defending yourself you could even lose your home.
