Additional interest

A person or business with a financial stake in the insured property, such as a lienholder, listed on the policy to get notices but not coverage.

Also called: additional interest endorsement, HO 04 10, interested party

An additional interest is a party other than the policyholder that has a financial stake in the property and is listed on the policy so the insurer will notify it. The most common one is the primary mortgage lender, but that lender is listed as the mortgagee and has stronger rights. Typical additional interests are a home equity lender, a contract-for-deed seller, a trust, or a landlord. The ISO endorsement Additional Interests, Residence Premises (HO 04 10) is the usual way to list them.

Listing an additional interest tells the insurer where to send notice if the policy is canceled or not renewed. It does not make that party an insured, and it generally does not entitle the party to claim money unless the policy also names it as a loss payee or mortgagee. That is the difference from an additional insured: the interest gets a letter, the insured gets coverage.

Keep the list current. After a refinance, the old lender should come off and the new one go on. A stale entry can delay claim checks or send cancellation notices to a company that no longer cares. If a second lender wants protection, ask your agent whether it should be listed as a mortgagee instead; see why your mortgage company is on the claim check.
