Fidelity National Financial is touting an alternative to traditional title insurance for home-equity loans and second mortgages. Dubbed “Master Lien Protection,” the product is being billed as the first “pool” insurance policy offered by a title insurer, in which coverage for the lender is provided by a master policy, with certificates on individual loans issued at closing. Like title insurance, the Fidelity product is designed to protect against liens and encumbrances.
