Binder

A binder is a temporary contract of insurance, issued by the carrier or by a producer on the carrier's behalf, that provides immediate proof of coverage while the formal policy documents are being prepared and delivered. Binders typically last 30 to 60 days, after which the actual policy takes over.

The binder lists the same core elements as the eventual policy: the named insured, the coverages, the limits, the deductible, and most importantly the effective date. During the binder period, if a covered loss happens, the carrier handles the claim as if the formal policy was already issued. The binder is legally enforceable.

Binders are common in three situations: closing on a house (lenders require proof of insurance before funding, and the binder serves that purpose), buying a new car (the binder confirms coverage before you drive off the lot), and switching carriers (the new carrier issues a binder to ensure no gap between the old policy ending and the new one starting).

Two important details about binders. First, the effective date on the binder is what determines when coverage starts, not the date you signed the application. If the binder shows noon tomorrow, you are not covered between signing and noon. Second, a binder can be cancelled by either party with proper notice, just like a policy. Carriers occasionally rescind a binder during underwriting if they discover the risk is outside their appetite.
